Referring now to FIGS. 1, 3-6, 10-12B, and 14-17, a vehicle 10 is illustrated. In FIG. 1, the vehicle 10 is an SUV. It is contemplated that the vehicle 10 may be one of a variety of types of vehicles (e.g., SUV, crossover, truck, sedan, van, coupe, etc.), in various embodiments. The vehicle 10 includes a cabin 12 for receiving passengers of the vehicle 10. The vehicle 10 includes a closure panel 14. In various embodiments, the vehicle 10 includes a plurality of closure panels 14. For example, in some implementations, the vehicle 10 may include side doors, windows, sunroofs, rear cargo doors, a trunk door, and/or a tailgate. The closure panel 14 may be operable between open and closed positions. In some embodiments, opening the closure panel 14 may provide access to the cabin 12 of the vehicle 10. In other words, in some embodiments, the cabin 12 of the vehicle 10 may be in fluid communication with an exterior environment 16 of the vehicle 10 if the closure panel 14 is in the open position. In an exemplary embodiment, wherein the closure panel 14 is a window disposed within a driver's side door of the vehicle 10, opening the window provides access to the cabin 12 of the vehicle 10.

In some embodiments, opening the closure panel 14 may provide access to a cargo area 18 of the vehicle 10. The cargo area 18 may be an area of the vehicle 10 for receiving cargo for storage therein. In some implementations, the cargo area 18 may be positioned within the cabin 12 of the vehicle 10. For example, the vehicle 10 may include a rear storage area 20 that is accessible via opening a lift gate of the vehicle 10. In some implementations, the cargo area 18 may be positioned outside of the cabin 12 of the vehicle 10. For example, the vehicle 10 may be a pickup truck, the cargo area 18 may be a bed of the truck, and the closure panel 14 may be a tailgate of the truck that gives access to the bed. In another example, the vehicle 10 may be an electric vehicle, the cargo area 18 may be a front trunk, and the closure panel 14 may be a hood that is moveable to an open position to provide access to the front trunk.

In various embodiments, the closure panel 14 may be operable to pivot about a pivot axis 22 between the open and closed positions. It is contemplated that, in various embodiments, the closure panel 14 may be operable to move between the open and closed positions in at least one of a variety of ways (e.g., translation, sliding, pivoting, etc.). In some embodiments, one or more closure panels 14 of the vehicle 10 may be operable to be power actuated between the open and closed positions via operation of one or more actuators 24 coupled to the vehicle 10. Various types of actuators 24 configured to move one or more closure panels 14 are contemplated (e.g., electric motor, pistons, solenoid, etc.).

In various embodiments, the vehicle 10 includes a rear gate assembly 26. The rear gate assembly 26 may be positioned at a rearward end 28 of the vehicle 10 and may be operable to selectively provide access to at least one of the cabin 12 of the vehicle 10 and the cargo area 18 of the vehicle 10. In some embodiments, the rear gate assembly 26 may include a single closure panel 14. For example, the rear gate assembly 26 may include a single trunk door operable to provide access to a trunk of the vehicle 10 in the open position. In another example, the rear gate assembly 26 may include a single tailgate of a truck operable to provide access to the bed of the truck in the open position. Further, in some examples, the rear gate assembly 26 may include a single-door lift gate that pivots to the open position to provide access to the rear storage area 20 positioned within the cabin 12 of the vehicle 10.

In some embodiments, the rear gate assembly 26 includes a plurality of closure panels 14. For example, in some embodiments, the rear gate assembly 26 may include a first closure panel 14 in the form a lift gate door, and a second closure panel 14 in the form of a rear glass panel 30 coupled to the lift gate door and operable to move relative to the lift gate door between the open and closed positions. In some embodiments, the first closure panel 14 is operable to pivot about a first pivot axis 32 a first direction from the closed position to the open position and the second closure panel 14 is operable to pivot about a second pivot axis 34 a second direction from the closed position to the open position, wherein the second direction is opposite the first direction. For example, in some embodiments, the rear gate assembly 26 includes a top gate panel 36 and a bottom gate panel 38 vehicle-downward of the top gate panel 36, wherein the first closure panel 14 comprises the top gate panel 36 and the second closure panel 14 comprises the bottom gate panel 38. The top gate panel 36 pivots a first direction (vehicle-upward) about the first pivot axis 32 from the closed position to the open position. The bottom gate panel 38 pivots a second direction (vehicle-downward) about the second pivot axis 34 that is opposite the first direction from the closed position to the open position. As illustrated in FIG. 6, the top gate panel 36 and the bottom gate panel 38 are coupled to each other in their respective closed positions.

In various embodiments, the closure panel 14 may include a distal end 40 that is located distally relative to the pivot axis 22 about which the closure panel 14 pivots between open and closed positions. In some implementations, wherein the vehicle 10 includes first and second closure panels 14, the first and second closure panels 14 may each include distal ends 40. For example, as illustrated in FIG. 1, the top gate panel 36 of the rear gate assembly 26 includes the distal end 40 that is located distally from the first pivot axis 32, and the bottom gate panel 38 of the rear gate assembly 26 includes the distal end 40 that is located distally from the second pivot axis 34. As illustrated in FIG. 6, the distal ends 40 of the top and bottom gate panels 36, 38 are proximate and/or in contact with each other in the closed positions of the top and bottom gate panels 36, 38. As further illustrated in FIGS. 1 and 3, the top gate panel 36 of the rear gate assembly 26 includes the rear glass panel 30.

Referring now to FIG. 3, a support feature 42 may be coupled to the rear gate assembly 26. The support feature 42 may facilitate cabin 12 and/or cargo area 18 ingress and/or egress. In some embodiments, the support feature 42 is coupled to at least one closure panel 14 of the rear gate assembly 26 that is operable to pivot vehicle-downward from the closed position to the open position (e.g., tailgate of a truck, bottom gate panel 38, etc.). The support feature 42 may be operable to move relative to the at least one closure panel 14 between a retracted position and a deployed position. In various embodiments, the position of the support feature 42 in the deployed position is further vehicle-downward than the position of the support feature 42 in the retracted position. In some implementations, the support feature 42 is concealed while in the retracted position. For example, in some implementations, the support feature 42 is concealed within the at least one closure panel 14 to which the support feature 42 is coupled while in the retracted position. The support feature 42 may be utilized for ingress and egress while in the deployed position.

In the embodiment illustrated in FIG. 3, the support feature 42 is a ramp 44 that extends out of the bottom gate panel 38 from the retracted position to the deployed position. The ramp 44 includes a first section 46 and a second section 48 operable to translate relative to the first section 46. The second section 48 being translatable relative to the first section 46 allows the ramp 44 to be concealed within the bottom gate panel 38 of the rear gate assembly 26 while in the retracted position, yet still extend from the bottom gate panel 38 to the ground in the deployed position. A variety of types of support features 42 operable to facilitate ingress and/or egress are contemplated. For example, in some embodiments, the support feature 42 may be a portion of a tailgate of a truck that is generally flush with the tailgate in the retracted position and forms one or more steps that extend generally downward from the tailgate if the tailgate is in the open position and the support feature 42 is in the deployed position. In some embodiments, the support feature 42 of the vehicle 10 may be operable to be power actuated between the retracted and deployed positions. One or more actuators 24 of the vehicle 10 may be configured to move the support feature 42 between the retracted and deployed positions. Various types of actuators 24 for moving the support feature 42 between the retracted and deployed positions are contemplated.

Other forms of input devices 62, such as one or more joysticks, digital input pads, buttons, dials, or the like, may be used in place of or in addition to touchscreen 64, in various implementations. In some embodiments, the system 50 may communicate via wireless communication with another embodiment of the HMI 58, such as with the portable electronic device 56. The portable electronic device 56 may also include the display 60 for displaying one or more images and other information to the user U. The portable electronic device 56 may be further able to receive user inputs via touchscreen 64 circuitry and/or other means. In addition, the portable electronic device 56 may provide feedback information, such as visual, audible, and tactile alerts.

Referring to FIGS. 2 and 4, the system 50 for the vehicle 10 may include a microphone 68 that detects sound. In various embodiments, the microphone 68 may be coupled to the vehicle 10. In some embodiments, the microphone 68 may be disposed within the cabin 12 of the vehicle 10. For example, the microphone 68 may be positioned within an overhead console of the vehicle 10 generally proximate to the driver of the vehicle 10.

The microphone 68 may be coupled to an exterior 70 of the vehicle 10, such that the microphone 68 is configured to detect sound originating outside of the cabin 12 of the vehicle 10. In some embodiments, the microphone 68 may be coupled to the portable electronic device 56. For example, in some embodiments, the microphone 68 may be integrated into a smartphone that is incorporated into the system 50 for the vehicle 10.

Referring still to FIGS. 2 and 4, the system 50 for the vehicle 10 may include a sensing system 72. The sensing system 72 includes at least one sensor 74. In various embodiments, the sensing system 72 may include various sensors 74 and/or devices that obtain or otherwise provide information pertaining to a status of the vehicle 10 and/or various other entities (e.g., user U of the vehicle 10, living being L in proximity to the vehicle 10, a trailer 130 attached to the vehicle 10, etc.), as described further herein. For example, in some instances, the sensing system 72 may include one or more imagers 76 or any other vision-based device. In some implementations, the sensing system 72 may include one or more imagers 76 that are disposed within the cabin 12 of the vehicle 10 and configured to capture an image of the cabin 12 of the vehicle 10. In some implementations, the sensing system 72 may include one or more imagers 76 that are configured to capture an image of the exterior environment 16 of the vehicle 10. For example, the sensing system 72 may include one or more of a center high-mount stop light (CHMSL) imager, a rear imager 78 coupled to or above at least one closure panel 14 of the rear gate assembly 26, a forward imager 80 proximate to a forward end 82 of the vehicle 10, a left-side side-view imager 84, and/or a right-side side-view imager 86. The one or more imagers 76 may include an area-type image sensor, such as a CCD or a CMOS image sensor, and image-capturing optics that capture an image of an imaging field of view defined by the image-capturing optics.

In some instances, various imagers 76 included in the sensing system 72 may be positioned to generally overlap in their respective fields of view. In this manner, image data from two or more of the imagers 76 may be combined into a single image or image patch, via an image processing routine. In such examples, the image data may be used to derive stereoscopic image data that can be used to reconstruct a three-dimensional scene of the area or areas within overlapped areas of the various fields of view including any objects (e.g., trailer 130, living being L, etc.) therein.

In some examples, the use of two images including the same object can be used to determine a location of the object relative to the two imagers 76, given a known spatial relationship between the imagers 76, through projective geometry of the imagers 76. In this respect, known programming and/or functionality may be utilized in an image processing routine to identify an object within the image data from the various imagers 76 within the sensing system 72. The image processing routine may include information related to the positioning of any of the imagers 76 present on the vehicle 10, including relative to a center of the vehicle 10.

Referring still to FIGS. 2 and 4, the sensing system 72 may include at least one of a host of types of sensors 74 operable to sense a proximity and/or position of one or more objects within the cabin 12 and/or in the exterior environment 16 of the vehicle 10. For example, in various embodiments, the sensing system 72 may include, but is not limited to, one or more of an ultrasonic sensor, a radio detection and ranging (radar) sensor, a sound navigation and ranging (SONAR) sensor, a light detection and ranging (LIDAR) sensor, a vision-based sensor, and/or any other type of sensor known in the art.

In various embodiments, the sensing system 72 includes at least one radar sensor 88. In some embodiments, the at least radar sensor 88 may include a plurality of radar sensors 88 that cooperate to provide imaging radar. For example, four radar sensors 88 (e.g., Texas Instruments AWR6843 Single Chip 60-GHz to 64-GHz automotive radar sensor) may be incorporated into a single printed circuit board, and the data collected by the four radar sensors 88 may be utilized to produce imaging radar. The at least one radar sensor 88 may emit a radar beam 90. The radar beam 90 may have different beam widths at different distances from the radar sensor 88. For example, the radar beam 90 may have a beam width of 180 degrees within three meters of the at least one radar sensor 88, and the radar beam 90 may have a beam width of 120 degrees at 100 meters from the at least one radar sensor 88. In some implementations, the beam width of the radar beam 90 may be adjusted via a controller 92, as described further herein. For example, the controller 92 may be operable to adjust the beam width of the radar beam 90 from 180 degrees within three meters of the at least one radar sensor 88 to 60 degrees within three meters of the at least one radar sensor 88, in some implementations.

In various embodiments, the sensing system 72 may include one or more temperature sensors 94. The one or more temperature sensors 94 may be operable to detect a temperature within the cabin 12 of the vehicle 10 and/or a temperature in the exterior environment 16 of the vehicle 10.

In some embodiments, the sensing system 72 may be operable to sense sunlight. It is contemplated that one or more of a variety of types of sensors 74 of the sensing system 72 may be utilized to sense sunlight. For example, in some embodiments, the sensing system 72 may include an optical sensor 96 configured to sense sunlight by converting optical energy introduced to the optical sensor 96 into an electric signal. The optical sensor 96 may absorb optical energy and sense sunlight using photoelectric effects that refer to discharge of electrons caused by absorption of optical energy. The optical sensor 96 may transmit the converted electric signal to the controller 92 of the sensing system 72, which may calculate the quantity of light based on the electric signal converted from the sensed sunlight. In some implementations, the sensing system 72 may be operable to sense how much light is entering the cabin 12 and/or a portion of the cabin 12. It is contemplated that, in various embodiments, the controller 92 may make a determination as to how much and/or at what locations sunlight is entering the vehicle 10 based on the sensing system 72 sensing one or more effects associated with sunlight. For example, the controller 92 may determine that sunlight is entering a portion of the cabin 12 based on image data received from at least one imager 76 of the vehicle 10 that reveals an illuminated portion of the vehicle 10 adjacent to a shaded portion of the vehicle 10.

The controller 92 may include the microprocessor 98 and/or other analog and/or digital circuitry for processing one or more routines. Further, the controller 92 may include the memory 100 for storing one or more routines.

It should be appreciated that the controller 92 may be a stand-alone dedicated controller 92 or may be a shared controller 92 integrated with other control functions, such as integrated with the sensing system 72, the portable electronic device 56, and/or other conceivable onboard or off-board vehicle control systems. It should further be appreciated that certain functions may be carried out by a dedicated processor. For example, image processing may be carried out by a dedicated processor, and the results of the image processing may be output to other components and systems of vehicle 10, including the microprocessor 98.

Referring now to FIGS. 1, 5, and 6, in some embodiments, wherein the vehicle 10 includes first and second closure panels 14 that are operable between open and closed positions, at least one sensor 74 may be coupled to the first closure panel 14 and configured to detect an obstruction 102 in a pivot path of the second closure panel 14. In other words, the at least one sensor 74 may be coupled to the first closure panel 14 and configured to detect an obstruction 102 in the path that the second closure panel 14 pivots between the open and closed positions. It is contemplated that, in various implementations, the at least one sensor 74 coupled to the first closure panel 14 may be operable to detect the obstruction 102 in the pivot path of the first closure panel 14 as well as detect the obstruction 102 in the pivot path of the second closure panel 14. In some implementations, wherein the at least one sensor 74 coupled to the first closure panel 14 is operable to detect the obstruction 102 in the pivot path of the second closure panel 14, the first closure panel 14 is operable to pivot about the first pivot axis 32 a first direction from the closed position to the open position, and the second closure panel 14 is operable to pivot about the second pivot axis 34 a second direction that is opposite the first direction from the closed position to the open position. Further, in some embodiments, the first closure panel 14 includes the distal end 40, which is located distally from the first pivot axis 32, and the at least one sensor 74 is coupled to the first closure panel 14 proximate to the distal end 40.

In the embodiment illustrated in FIGS. 1 and 5, the vehicle 10 includes the rear gate assembly 26. In the illustrated embodiments, the rear gate assembly 26 includes the first closure panel 14 in the form of the top gate panel 36, and the second closure panel 14 in the form of the bottom gate panel 38. The top gate panel 36 is operable to pivot vehicle-upward about the first pivot axis 32 from the closed position to the open position, and the bottom gate panel 38 is operable to pivot vehicle-downward about the second pivot axis 34 from the closed position to the open position. As illustrated in FIGS. 1 and 5, the at least one sensor 74 is coupled to the top gate panel 36 proximate to the distal end 40 of the top gate panel 36. The at least one sensor 74 coupled to the top gate panel 36 is configured to detect the obstruction 102 in the pivot path of the bottom gate panel 38, as illustrated in FIG. 5.

It is contemplated that the at least one sensor 74 coupled to the first closure panel 14 may include one or more of a variety of types of sensors 74 operable to detect the obstruction 102 in the pivot path of the second closure panel 14. For example, the at least one sensor 74 may include one or more of the sensor types of the sensing described herein (e.g., LIDAR, imager 76, SONAR, etc.). In some embodiments, the at least one sensor 74 may include at least one radar sensor 88. As described herein, the at least one radar sensor 88 may emit the radar beam 90. In some embodiments, the radar beam 90 emitted by the at least one radar sensor 88 coupled to the first closure panel 14 may be emitted into the cabin 12 of the vehicle 10 and the exterior environment 16 of the vehicle 10 in the closed position of the first closure panel 14. For example, as illustrated in FIG. 10, the at least one radar sensor 88 is coupled to the distal end 40 of the top gate panel 36 and is configured to emit the radar beam 90 into the cabin 12 and exterior environment 16 of the vehicle 10 in the closed position with the bottom gate panel 38 in the open position. Further, as illustrated in FIG. 6, the at least one radar sensor 88 coupled to the top gate panel 36 is configured to emit the radar beam 90 into the cabin 12 and exterior environment 16 of the vehicle 10 in the closed position of the top gate panel 36 and the bottom gate panel 38. In some implementations, radar beam 90 is emitted wholly into the exterior environment 16 of the vehicle 10 in the open position of the first closure panel 14. For example, as illustrated in FIG. 17, the radar beam 90 of the at least one radar sensor 88 coupled to the open top gate panel 36 is emitted generally vehicle-rearward, such that the radar beam 90 does not intersect with the cabin 12 of the vehicle 10.

In various embodiments, the controller 92 receives data from the at least one sensor 74 coupled to the first closure panel 14 and prompts a vehicle action based on the received data. In some embodiments, the controller 92 may control operation of the first closure panel 14 and/or the second closure panel 14 based on the data received from the at least one sensor 74. For example, the at least one sensor 74 coupled to the first closure panel 14 may detect an obstruction 102 in the pivot path of second closure panel 14 as the second closure panel 14 is being power actuated by one or more actuators 24 from the open position to the closed position. In response to receiving the data from the at least one sensor 74 indicating the detection of the obstruction 102, the controller 92 may control operation of the second closure panel 14 by prompting the actuator 24 to halt movement of the second closure panel 14. It is contemplated that the controller 92 may control operation of one or more closure panels 14 by prompting a variety of actions (e.g., locking, unlocking, moving toward the open position, moving toward the closed position, halting movement, etc.).

In the exemplary embodiment illustrated in FIG. 5, the vehicle 10 includes the rear gate assembly 26, which includes the top gate panel 36 and the bottom gate panel 38. At least one radar sensor 88 is coupled to the top gate panel 36 and emits the radar beam 90 that intersects the pivot path of the bottom gate panel 38 with the top gate panel 36 in the open position. In operation, the user U may attempt to close the bottom gate panel 38 remotely via entry of an input into the portable electronic device 56 (e.g., key fob). The controller 92 then controls operation of the bottom gate panel 38 by not moving the bottom gate panel 38 to the closed position as requested based on data received from the at least one radar sensor 88 indicating detection of the obstruction 102 in the pivot path of the bottom gate panel 38, as illustrated in FIG. 5. In various implementations, the controller 92 may prompt additional vehicle actions to alert the user U that the request to close the bottom gate panel 38 was denied. For example, the controller 92 may prompt the sound source device 52 to emit an audible alert if a requested action is not executed.

Referring now to FIG. 6, in some embodiments, the at least one sensor 74 coupled to the first closure panel 14 and operable to detect the obstruction 102 in the pivot path of the second closure panel 14 may be further operable to detect the obstruction 102 in the travel path of the vehicle 10. In some implementations, the at least one sensor 74 may be operable to detect the obstruction 102 in the travel path of the vehicle 10 with the first and second closure panels 14 in the closed positions. In various embodiments, the at least one sensor 74 may detect an obstruction 102 in the pivot path of the first and/or second closure panels 14 in a first vehicle state, and the at least one sensor 74 may be operable to detect the obstruction 102 in the travel path of the vehicle 10 in a second vehicle state. Further, the controller 92 may interpret and/or respond to data received from the at least one sensor 74 differently in the first vehicle state than the second vehicle state. The presence and/or absence of a variety of vehicle conditions may determine whether the vehicle 10 is in the first vehicle state or the second vehicle state (e.g., position of closure panels 14, whether the vehicle 10 is turned on, whether the vehicle 10 is in gear, whether a command to open the closure panel 14 has been entered, speed of the vehicle 10, etc.). In an exemplary embodiment, the first vehicle state may occur if the vehicle 10 is in a reverse gear, and the second vehicle state may occur if the vehicle 10 is not in reverse and a closure panel 14 operation request (e.g., open the closure panel 14, close the closure panel 14, etc.) is received.

In various embodiments, the controller 92 may prompt a vehicle action based on the at least one sensor 74 detecting the obstruction 102 in the travel path of the vehicle 10. For example, the controller 92 may prompt the HMI 58 to display a visual alert, the sound source device 52 to emit an audible alert, and/or a vehicle brake system to apply a brake in response to the at least one sensor 74 detecting the obstruction 102 in the travel path of the vehicle 10. Various vehicle actions are contemplated.

In an exemplary embodiment, the vehicle 10 includes the rear gate assembly 26, which is comprised of the top gate panel 36 and the bottom gate panel 38. At least one radar sensor 88 is coupled to the top gate panel 36 and emits the radar beam 90. In operation, the user U of the vehicle 10 reverses the vehicle 10 with both the top gate panel 36 and the bottom gate panel 38 in the closed positions, as illustrated in FIG. 6. While the vehicle 10 is reversing, a portion of the radar beam 90 of the at least one radar sensor 88 is emitted vehicle-rearward into the exterior environment 16 rearward of the vehicle 10. As the vehicle 10 approaches an object in the travel path of the vehicle 10, the at least one radar sensor 88 senses the obstruction 102 and transmits data to the controller 92. The controller 92 receives the data indicating the presence of the obstruction 102 in the travel path of the vehicle 10 and prompts the sound source device 52 to emit an audible warning. Hearing the audible warning, the driver stops the vehicle 10 short of the obstruction 102, parks, and turns the vehicle 10 off. When the driver later attempts to remotely open the rear gate assembly 26, the at least one radar sensor 88 coupled to the top gate panel 36 senses whether any obstructions 102 are present in the pivot path of the top gate panel 36 and the bottom gate panel 38 and transmits data to the controller 92. The controller 92 prompts the top and bottom gate panels 36, 38 to open based on the data received from the at least one radar sensor 88 indicating that no obstructions 102 are present.

Referring now to FIGS. 7 and 8, in some embodiments, the sensing system 72 may sense at least one characteristic of the user U positioned in the exterior environment 16 of the vehicle 10, and the controller 92 may determine a load carrying condition of the user U based on the at least one characteristic of the user U sensed by the sensing system 72. The controller 92 may be operable to prompt various vehicle actions based on the determined load carrying condition. In various embodiments, the controller 92 is configured to control operation of at least one closure panel 14 of the vehicle 10 based on the determined load carrying condition. For example, the controller 92 may prompt actuation of a first closure panel 14 from the closed position to the open position based on a determination of a first load carrying condition of the user U, and the controller 92 may prompt actuation of the first closure panel 14 and a second closure panel 14 from the closed positions to the open positions, respectively, based on a determination of a second load carrying condition of the user U.

The sensing system 72 may be configured to sense a variety of characteristics of the user U in the exterior environment 16 of the vehicle 10. In some embodiments, the sensing system 72 may sense at least one characteristic of at least one hand of the user U. For example, the sensing system 72 may sense the position of one or both of the hands of the user U (e.g., at the user's side, in front of the user U, etc.) as the user U approaches the vehicle 10, movement of one or both of the user's hands as the user U walks, and/or the shape of the user's hands (e.g., open, closed, etc.). Further, the sensing system 72 may sense at least one characteristic of a gait of the user U. For example, the sensing system 72 may sense the speed that the user U is walking, the position of various portions of the user U (e.g., head, shoulders, etc.), and/or the posture of the user U approaching the vehicle 10 (e.g., whether the user U is standing up straight or hunched over). In some implementations, the sensing system 72 may sense at least one characteristic of an object 104 held by the user U. For example, the sensing system 72 may sense the shape, size, and/or position of the object 104 held by the user U. It is contemplated that the sensing system 72 may sense a plurality of characteristics (e.g., object 104, gait, hands, etc.) simultaneously, in some embodiments. Further, a variety of other characteristics may be sensed by the sensing system 72, in some embodiments.

It is contemplated that various types of sensors 74 and devices of the sensing system 72 may be utilized to sense the at least one characteristic of the user U in the exterior environment 16 of the vehicle 10. For example, one or more LIDAR sensors, imagers 76, SONAR sensors, and/or radar sensors 88 of the sensing system 72 may be utilized to sense the at least one characteristic of the user U. In some embodiments, the sensing system 72 may utilize at least one radar sensor 88 to sense the at least one characteristic of the user U. For example, a plurality of radar sensors 88 that in cooperation produce imaging radar, as described herein, may be utilized in some embodiments. In some implementations, one or more imagers 76 of the sensing system 72 may be utilized to sense the at least one characteristic of the user U. For example, the rear imager 78 may capture image data of the at least one characteristic of the user U. It is contemplated that a plurality of types of sensors 74 of the sensing system 72 may be utilized to sense the at least one characteristic of the user U cooperatively via sensor fusion, in various implementations.

Referring now to FIGS. 7 and 8, the controller 92 may determine the load carrying condition of the user U based on the characteristics of the user U sensed by the sensing system 72. In some embodiments, the controller 92 may determine a first load carrying condition of the user U based on the data gathered by the sensing system 72 while the sensing system 72 is sensing the user U with at least one free hand. For example, the controller 92 may determine the first load carrying condition of the user U based on the sensed swinging movement of the hand as the user U walks and/or the sensed shape of the open-palmed hand that occurs when the user U approaches the vehicle 10 with at least one hand free. The controller 92 may determine a second load carrying condition of the user U based on the data gathered by the sensing system 72 while the sensing system 72 is sensing the user U with both hands full. For example, the controller 92 may determine the second load carrying condition of the user U based on the sensed positions of the hands in front of the user U and/or the sensed shape of the closed fists of the user U that occurs when the both hands of the user U are full.

In some embodiments, the controller 92 may determine the load carrying condition of the user U based on the data gathered by the sensing system 72 while the sensing system 72 is sensing the gait of the user U. For example, the controller 92 may determine a first load carrying condition based on data from the sensing system 72 indicating the user's gait conforms to a natural gait of the user U, wherein the user U is unencumbered or not carrying a load. Further, the controller 92 may determine a second load carrying condition based on data from the sensing system 72 that indicates the gait of the user U is not natural and/or conforms with a load carrying gait. For example, the sensing system 72 may sense the user U walking slowly with slumped shoulders, and the controller 92 may determine a second load carrying condition of the user U as a result.

In some embodiments, the controller 92 determines the load carrying condition of the user U based on at least one sensed characteristic of the object 104 held by the user U. For example, the controller 92 may determine a first load carrying condition based on the object 104 held by the user U being smaller than a predetermined size threshold. The controller 92 may determine a second load carrying condition based on the object 104 carried by the user U being above the predetermined size threshold. In an exemplary embodiment, the controller 92 may determine a first load carrying condition of the user U based on the sensing system 72 sensing the user U holding an object 104 of a first size, and the controller 92 may determine a second load carrying condition of the user U based on the sensing system 72 sensing the user U holding an object 104 of a second size, wherein the second size is greater than the first size. It is contemplated that, in various embodiments, the controller 92 may determine the load carrying condition of the user U based on a plurality of sensed characteristics of the user U. For example, the controller 92 may determine the load carrying condition of the user U based on the sensed characteristics of the user's hands, gait, and/or the object 104 held by the user U. A variety of other user U characteristics are contemplated.

In various embodiments, the controller 92 may be operable to prompt various vehicle actions based on the determined load carrying condition of the user U. In an exemplary embodiment, the vehicle 10 includes the rear gate assembly 26, which includes the top gate panel 36 and the bottom gate panel 38, as illustrated in FIG. 1. In operation, the user U approaches the rear gate assembly 26 by walking with a natural gait while carrying a handbag with one hand and no items in the other hand, as illustrated in FIG. 7. The sensing system 72 senses the user U approaching in this manner and transmits data indicative of one or more of these characteristics of the user U to the controller 92. The controller 92 determines, based on data received from the sensing system 72, a first load carrying condition of the user U. In response to the determination of the first load carrying condition of the user U the controller 92 prompts movement of the top gate panel 36 from the closed position to the open position. The bottom gate panel 38 remains in the closed position. Later, the user U approaches the rear gate assembly 26 by walking with an encumbered gait, wherein the user's shoulders are hunched over, while carrying a box with both hands, as illustrated in FIG. 8. The sensing system 72 senses the user U approaching in this manner and transmits data indicative of one or more of these characteristics of the user U to the controller 92. The controller 92 determines, based on the received data, a second load carrying condition of the user U. In response to the determination of the second load carrying condition of the user U, the controller 92 prompts movement of the top and bottom gate panels 36, 38 from the closed positions to the open positions.

Referring now to FIG. 9, a method 106 for providing access to the vehicle 10 is disclosed. The method 106 for providing access to the vehicle 10 includes the step 108 of sensing the user U positioned in the exterior environment 16 of the vehicle 10 with the sensing system 72. In some implementations, the step 108 of sensing the user U positioned in the exterior environment 16 of the vehicle 10 comprises sensing the user U approaching the vehicle 10. The step 108 may comprise sensing the user U approaching a rear portion of the vehicle 10, such as the rear gate assembly 26 of the vehicle 10.

The method 106 for providing access to the vehicle 10 may further include the step 110 of determining a load carrying condition of the user U with a controller 92 based on data from the sensing system 72. As described herein, in various embodiments, the controller 92 may determine the load carrying condition based on at least one sensed characteristic of the user U, such as one or more characteristics of the hands of the user U, the gait of the user U, and/or an object 104 carried by the user U. For example, if the user U has a free hand, as illustrated in FIG. 7, the controller 92 may determine a first load carrying condition. Conversely, if the hands of the user U are full, as illustrated in FIG. 8, the controller 92 may determine a second load carrying condition of the user U.

The method 106 of providing access to the vehicle 10 may further include the step 112 of opening at least one of a first closure panel 14 of the vehicle 10 and a second closure panel 14 of the vehicle 10 based on the determined load carrying condition of the user U. In various embodiments, the first closure panel 14 is opened if the first load carrying condition is determined by the controller 92, and the first and second closure panels 14 are opened if the second load carrying condition is determined by the controller 92. In some implementations, the first closure panel 14 forms at least a portion of the rear gate assembly 26 of the vehicle 10. For example, the first closure panel 14 may be an openable rear glass panel 30 coupled to a lift gate, in some embodiments. In another embodiment, the first closure panel 14 may be the top gate panel 36 of the rear gate assembly 26 that includes the top gate panel 36 and the bottom gate panel 38. In some embodiments, the first closure panel 14 is operable to pivot about the first pivot axis 32 a first direction from the closed position to the open position and the second closure panel 14 is operable to pivot about the second pivot axis 34 a second direction from the closed position to the open position, wherein the second direction is opposite the first direction. In some embodiments, the first and second closure panels 14 are top and bottom gate panels 36, 38 of the rear gate assembly 26 of the vehicle 10, respectively. The bottom gate panel 38 is positioned vehicle-downward of the top gate panel 36 and the first and second closure panels 14 are coupled to each other in the closed positions, as illustrated in FIG. 6.

Referring now to FIGS. 2 and 10-12B, in some embodiments, the sensing system 72 may detect a living being L. The living being L may be the user U, as described herein, or an animal. In some implementations, the living being L may be a four-legged animal, such as a dog or a cat. At least one of a variety of types of sensors 74 included in the sensing system 72 may be utilized to sense the living being L. For example, one or more LIDAR sensors, imagers 76, SONAR sensors, and/or radar sensors 88 of the sensing system 72 may be utilized to sense the living being L, in some embodiments.

Referring still to FIGS. 2 and 10-12B, as described herein, the sensing system 72 transmits data to the controller 92. The controller 92 may authenticate the identity of the living being L and/or determine the position of the living being L based on the data received from the sensing system 72. In some embodiments, image data transmitted from at least one imager 76 of the sensing system 72 may be utilized by the controller 92 to authenticate the identity of the living being L. In some implementations, the controller 92 may process the image data and/or utilize otherwise processed image data to perform a facial recognition analysis of the living being L to authenticate the identity of the living being L. It is contemplated that various other biometric comparisons may be performed to authenticate the identity of the living being L, in various implementations. For example, the size, color, shape, and/or position of living being L and/or one or more portions thereof, as sensed by the sensing system 72, may be utilized to authenticate the identity of the living being L. It is contemplated that the data collected by the sensing system 72 may be compared against reference data stored within memory 100. For example, one or more reference images of the living being L may be stored in memory 100 and compared to image data of the living being L collected by the at least one imager 76 of the sensing system 72 to authenticate the identity of the living being L.

As described herein, the controller 92 may determine the position of the living being L based on the data received from the sensing system 72. In some embodiments, the controller 92 may determine the position of the living being L relative to the vehicle 10 and/or a portion of the vehicle 10. In some embodiments, the controller 92 determines the position of the living being L relative to the rear gate assembly 26 of the vehicle 10. As described herein, a variety of sensors 74 of the sensing system 72 may be utilized to sense the proximity and/or position of the living being L, in various embodiments. In an exemplary embodiment, the rear gate assembly 26 of the vehicle 10 includes top and bottom gate panels 36, 38, and at least one radar sensor 88 is coupled to the top gate panel 36. The controller 92 may determine the position of the living being L based on data received from the at least one radar sensor 88.

Referring still to FIGS. 2 and 10-12B, the controller 92 may control operation of the rear gate assembly 26 of the vehicle 10 based on the determined position of the living being L and/or the authenticated identity of the living being L. In such embodiments, the rear gate assembly 26 of the vehicle 10 may include at least one closure panel 14 that is operable to pivot vehicle-downward from the closed position to the open position. The closure panel 14 may selectively provide access to the cabin 12 of the vehicle 10 and/or the cargo area 18 of the vehicle 10, in various embodiments. For example, in some embodiments, the vehicle 10 is a truck and the at least one closure panel 14 is the tailgate of the truck that pivots vehicle-downward from the closed position to the open position to provide access to the cargo area 18 of the vehicle 10, which is the bed of the truck. In another exemplary embodiment, the rear gate assembly 26 of the vehicle 10 includes the top gate panel 36 and the bottom gate panel 38, as illustrated in FIG. 1. The bottom gate panel 38 is operable to pivot vehicle-downward from the closed position to the open position to provide access to the cabin 12 of the vehicle 10. Various types of rear gate assemblies 26 are contemplated.

In various embodiments, wherein the controller 92 is configured to control operation of the rear gate assembly 26 based on the determined position of the living being L and/or the authenticated identity of the living being L, the rear gate assembly 26 of the vehicle 10 includes the support feature 42. As described herein, the support feature 42 may be coupled to the at least one closure panel 14 that is operable to pivot vehicle-downward from the closed position to the open position. The support feature 42 may move relative to the at least one closure panel 14 between the retracted position and the deployed position. As illustrated in FIGS. 10 and 11, in the open position of the at least one closure panel 14, the position of the support feature 42 in the deployed position is further vehicle-downward than the position of the support feature 42 in the retracted position. In the illustrated embodiment, the support feature 42 comprises the ramp 44 that extends out of the at least one closure panel 14 from the retracted position to the deployed position. As described herein, various types of support features 42 operable to move between the retracted and deployed positions are contemplated.

In various embodiments, the controller 92 may control operation of the rear gate assembly 26 by controlling movement of the closure panel 14 and/or the support feature 42 via one or more actuators 24 based on the determined position of the living being L and/or the authenticated identity of the living being L. In an exemplary embodiment, the controller 92 may receive data from the sensing system 72 and determine that the living being L is positioned within a predetermined distance from the at least one closure panel 14 of the rear gate assembly 26 of the vehicle 10. Further, the controller 92 may authenticate the identity of the living being L by determining that the identity of the living being L matches an identity profile stored in memory 100. In response, the controller 92 may move the at least one closure panel 14 from the closed position to the open position and move the support feature 42 from the retracted position to the deployed position via the one or more actuators 24. It is contemplated that, in some embodiments, one of the at least one closure panel 14 of the rear gate assembly 26 and the support feature 42 coupled with the closure panel 14 may be operated in response to the controller 92 authenticating the identity of the living being L and/or determining the position of the living being L. For example, in some embodiments, the at least one closure panel 14 may move from the closed position to the open position. In other embodiments, the at least one closure panel 14 may be in the open position, and the support feature 42 may move from the retracted position to the deployed position.

In various embodiments, the controller 92 may control operation of the rear gate assembly 26 based on the determined position of the living being L relative to a portion of the vehicle 10. In some embodiments, the controller 92 may control operation of the rear gate assembly 26 based on the position of the living being L relative to the rear gate assembly 26 of the vehicle 10. For example, the controller 92 may control operation of the rear gate assembly 26 based on the proximity of the living being L to the rear gate assembly 26. In some embodiments, the controller 92 may control operation of the rear gate assembly 26 based on the determined position of the living being L within the cabin 12 of the vehicle 10. For example, the imager 76 disposed within the cabin 12 of the vehicle 10 may collect image data of the living being L positioned inside of the cabin 12 of the vehicle 10 and transmit the image data to the controller 92. The controller 92 may determine that the living being L is positioned within a predetermined proximity to the rear gate assembly 26 of the vehicle 10 and prompt one or more actuators 24 to move the support feature 42 from the retracted position to the deployed position.

In some embodiments, the controller 92 may control operation of the rear gate assembly 26 of the vehicle 10 based on the position of the living being L in the exterior environment 16 of the vehicle 10. For example, at least one radar sensor 88 of the sensing system 72 of the vehicle 10 may detect the living being L in the exterior environment 16 of the vehicle 10 and transmit corresponding data to the controller 92. The controller 92 may determine that the living being L is within a predetermined proximity of the rear gate assembly 26 of the vehicle 10 based on the data received from the at least one radar sensor 88. In response, the controller 92 may prompt one or more actuators 24 to move the support feature 42 from the retracted position to the deployed position.

Referring now to FIGS. 10-12B, in an exemplary embodiment, the rear gate assembly 26 of the vehicle 10 includes the top gate panel 36 and the bottom gate panel 38. The support feature 42 is coupled to the bottom gate panel 38. At least one radar sensor 88 is coupled to the top gate panel 36. A first imager 76 is coupled to the exterior 70 of the vehicle 10, and a second imager 76 is positioned within the cabin 12 of the vehicle 10. The first imager 76 has a field of view generally vehicle-rearward of the rear gate assembly 26 of the vehicle 10. The second imager 76 has a field of view that generally encompasses the rear storage area 20 within the cabin 12 of the vehicle 10. In operation, a dog is initially within the rear storage area 20 of the vehicle 10 while the top and bottom gate panels 36, 38 of the rear gate assembly 26 are open. Next, the dog moves onto the open bottom gate panel 38 from the rear storage area 20. The second imager 76 captures image data of the dog positioned on the open bottom gate panel 38 and transmits the image data to the controller 92. The controller 92 determines the position of the dog based on the image data received from the second imager 76 and prompts movement of the support feature 42 from the retracted position to the deployed position based on the determined position, as illustrated in FIG. 12A. Next, the dog walks down the support feature 42 and onto the ground in the exterior environment 16 of the vehicle 10, and the controller 92 prompts movement of the support feature 42 from the deployed position back to the retracted position, as illustrated in FIG. 12B. The dog subsequently leaves the immediate vicinity of the vehicle 10 and then returns, as illustrated in FIG. 10. As the dog approaches the rear gate assembly 26, the first imager 76 collects image data of the dog, and the at least one radar sensor 88 senses the dog proximate to the bottom gate panel 38. The image data from the first imager 76 and the data from the at least one radar sensor 88 is transmitted to the controller 92. The controller 92 authenticates the identity of the dog by comparing the captured image data with an identity profile stored in memory 100, and the controller 92 determines the position of the dog based on the data received from the at least one radar sensor 88. Next, the controller 92 prompts movement of the support feature 42 from the retracted position to the deployed position based on the authentication of the identity of the dog and the determined position of the dog. The dog is then able to climb onto the support feature 42 and return to the cabin 12 of the vehicle 10, as illustrated in FIG. 11.

Referring now to FIG. 13, a method 114 for providing access to the vehicle 10 is illustrated. The method 114 for providing access to the vehicle 10 may include the step 116 of detecting the living being L with the sensing system 72 of the vehicle 10. In some embodiments, the living being L may be a four-legged being, such as a dog or a cat. As such, the method 114 for providing access to the vehicle 10 may include the step 116 of detecting a four-legged living being L with the sensing system 72 of the vehicle 10. As described above, the sensing system 72 may employ a variety of sensors 74 to sense the four-legged living being L (e.g., imagers 76, radar sensors 88, etc.). In some embodiments, the sensing system 72 may sense the living being L in the exterior environment 16 of the vehicle 10, the cabin 12 of the vehicle 10, and/or the cargo area 18 of the vehicle 10.

The method 114 for providing access to the vehicle 10 may include the step 118 of authenticating the identity of the living being L. The step 118 of authenticating the identity of the living being L may be performed by the controller 92 in response to receiving data from the sensing system 72. The controller 92 may authenticate the identity of the living being L in a variety of manners (e.g., facial recognition, biometric comparison, etc.) as described above, in various implementations. In some embodiments, the step 118 of authenticating the living being L may include the step 120 of determining the size of the living being L. The step 120 of determining the size of the living being L may be performed by the controller 92 via the processing of data received from the sensing system 72. In an exemplary embodiment of the method 114 for providing access to the vehicle 10, at least one imager 76 of the sensing system 72 of the vehicle 10 collects image data of the living being L, and the controller 92 processes that image data to determine the size of the living being L. It is contemplated that a variety of other characteristics of the living being L may be determined in the step 118 of authenticating the identity of the living being L, in some implementations (e.g., color, shape, etc.).

The method 114 for providing access to the vehicle 10 may further include the step 122 of determining the position of the living being L. In some embodiments, the step 122 of determining the position of the living being L may include determining the position of the living being L relative to the vehicle 10 and/or a portion of the vehicle 10. For example, the position of the living being L relative to the rear gate assembly 26 of the vehicle 10 may be determined. In some embodiments, the position of the living being L in the exterior environment 16, the cabin 12, and/or the cargo area 18 of the vehicle 10 may be determined. The position of the living being L may be determined via the controller 92 based on data received from the sensing system 72 of the vehicle 10. As described herein, one or more of a variety of types of sensors 74 of the sensing system 72 may be utilized to determine the position of the living being L.

The method 114 for providing access to the vehicle 10 may further include the step 124 of detecting a gesture of the living being L. The gesture may be detected with the sensing system 72. In some examples, at least one radar sensor 88 of the sensing system 72 coupled to the top gate panel 36 of the rear gate assembly 26 may detect the gesture of the living being L when the living being L is proximate to the rear gate assembly 26 of the vehicle 10. A variety of gestures are contemplated. For example, in some embodiments, wherein the living being L is a human user U of the vehicle 10, the gesture that is detected may be pointing with the user's U hand/or swinging of the user's U foot. In some embodiments, wherein the living being L is a four-legged animal, the gesture that is detected may include standing on the hind legs, jumping, and/or swiping at the air with a front leg.

The method 114 for providing access to the vehicle 10 may further include the step 126 of operating the rear gate assembly 26 of the vehicle 10. The step 126 of operating the rear gate assembly 26 may include movement of at least one closure panel 14 of the rear gate assembly 26 of the vehicle 10 between the open and closed positions and/or movement of the support feature 42 between the retracted and deployed positions. For example, in some embodiments, wherein the rear gate assembly 26 includes the top gate panel 36, the bottom gate panel 38, and the support feature 42 operably coupled to the bottom gate panel 38, the step 126 of operating the rear gate assembly 26 may include at least one of pivoting the top gate panel 36 vehicle-upward from the closed position to the open position, pivoting the top gate panel 36 vehicle-downward from the open position to the closed position, pivoting the bottom gate panel 38 vehicle-downward from the closed position to the open position, pivoting the bottom gate panel 38 vehicle-upward from the open position to the closed position, moving the support feature 42 from the retracted position to the deployed position, and moving the support feature 42 from the deployed position to the retracted position. In some embodiments, the step 126 of operating the rear gate assembly 26 of the vehicle 10 may include at least one of pivoting at least one closure panel 14 of the rear gate assembly 26 vehicle-downward from the closed position to the open position and moving the support feature 42 coupled to the at least one closure panel 14 from the retracted position to the deployed position, wherein, in the open position of the at least one closure panel 14, the position of the support feature 42 in the deployed position is further vehicle-downward than the support feature 42 in the retracted position.

In various embodiments, the step 126 of operating the rear gate assembly 26 of the vehicle 10 may be controlled by the controller 92. In some implementations, the controller 92 may control operation of the rear gate assembly 26 of the vehicle 10 based on authentication of the identity of the living being L, the position of the living being L, and/or based on a detected gesture of the living being L. In some embodiments, the controller 92 may control operation of the rear gate assembly 26 of the vehicle 10 based on the determined size of the living being L. In an exemplary embodiment, the rear gate assembly 26 may be operated based on the size of the living being L and the detected gesture of the living being L.

Referring now to FIGS. 14 and 15, in some embodiments, the vehicle 10 includes first and second closure panels 14 that are operable between open and closed positions, and at least one sensor 74 that is coupled to the first closure panel 14 and configured to detect precipitation 128. In such embodiments, the controller 92 may prompt movement of the first closure panel 14 from a first open position to a second open position based on the detected precipitation 128.

Referring still to FIGS. 14 and 15, in some embodiments, the first closure panel 14 may form at least a portion of the rear gate assembly 26 of the vehicle 10. For example, the first closure panel 14 may be a single-door lift gate that pivots to the open position to provide access to the rear storage area 20 positioned within the cabin 12 of the vehicle 10. The second closure panel 14 may be one of a variety of closure panels 14 of the vehicle 10 (e.g., window, side door, sunroof, etc.). In some embodiments, the second closure panel 14 may form at least a portion of the rear gate assembly 26 of the vehicle 10. In an exemplary embodiment, the first and second closure panels 14 may form portions of the rear gate assembly 26, as described further herein.

Referring now to FIGS. 1, 14, and 15, in some implementations, the first closure panel 14 is operable to pivot a first direction about the first pivot axis 32 away from the closed position, and the second closure panel 14 is operable to pivot a second direction about the second pivot axis 34 away from the closed position, wherein the second direction is opposite the first direction. This is the case in the exemplary embodiment illustrated in FIG. 1, wherein the rear gate assembly 26 includes the top gate panel 36 and the bottom gate panel 38 vehicle-downward of the top gate panel 36; the first closure panel 14 comprises the top gate panel 36 and the second closure panel 14 comprises the bottom gate panel 38. In such embodiments, the first and second closure panels 14 are coupled to each other when the first and second closure panels 14 are in the closed positions.

Referring now to FIGS. 14 and 15, at least one sensor 74 that detects the precipitation 128 may be coupled to the first closure panel 14. It is contemplated that the at least one sensor 74 may be at least one of a host of types of sensors 74 configured to detect precipitation 128, in various embodiments. For example, the at least one sensor 74 may be a rain sensor that emits an infrared light beam and detects precipitation 128 by sensing the amount of light that is reflected back to the rain sensor. In some embodiments, the at least one sensor 74 may include at least one radar sensor 88. The at least one radar sensor 88 may emit the radar beam 90, as described herein. In various embodiments, the at least one radar sensor 88 may be operable to detect the precipitation 128 in the exterior environment 16 of the vehicle 10. In some embodiments, the at least one radar sensor 88 may detect the precipitation 128 entering the cabin 12 of the vehicle 10. For example, as illustrated in FIG. 14, the at least one radar sensor 88 coupled to the open first closure panel 14 emits the radar beam 90, such that a portion of the radar beam 90 is emitted into the cabin 12 of the vehicle 10, and a portion of the radar beam 90 is emitted into the exterior environment 16 of the vehicle 10. The at least one radar sensor 88 may detect the precipitation 128 entering the cabin 12 of the vehicle 10 by detecting the precipitation 128 that coincides with the portion of the radar beam 90 that is emitted into the cabin 12 of the vehicle 10. In some embodiments, the at least one radar sensor 88 may be configured to detect the speed and/or direction of the movement of the precipitation 128, as described further herein.

Referring now to FIGS. 2, 14, and 15, the controller 92 may prompt movement of the first closure panel 14 from the first open position to the second open position based on the at least one sensor 74 detecting the precipitation 128. In various embodiments, the controller 92 may prompt movement of the first closure panel 14 from the first open position to the second open position based on the at least one sensor 74 detecting the precipitation 128 entering the cabin 12 of the vehicle 10. In some embodiments, wherein the at least one sensor 74 includes at least one radar sensor 88 operable to emit the radar beam 90 at least partially into the cabin 12 of the vehicle 10, the controller 92 may prompt movement of the first closure panel 14 from the first open position to the second open position based on the detection of the precipitation 128 that coincides with the portion of the radar beam 90 that is emitted into the cabin 12. In some embodiments, wherein the at least one sensor 74 includes at least one radar sensor 88, the controller 92 may prompt movement of the first closure panel 14 from the first open position to the second open position based on the sensed direction of movement of the precipitation 128 and/or the sensed speed of movement of the precipitation 128. In an exemplary embodiment, the at least one radar sensor 88 may detect the direction of movement of the precipitation 128 and transmit corresponding data to the controller 92. The controller 92 may determine that the precipitation 128 is entering the cabin 12 of the vehicle 10 based on the data received from the at least one radar sensor 88 and prompt movement of the first closure panel 14 in response. In various embodiments, the controller 92 may prompt movement of the first closure panel 14 and/or the second closure panel 14 via actuation of one or more actuators 24 operably coupled with the first and/or second closure panels 14.

Referring now to FIGS. 6, 14, and 15, the position of the first closure panel 14 in the first open position may be further than the position of the first closure panel 14 in the second open position from the position of the first closure panel 14 in the closed position. As illustrated in FIG. 15, wherein the first closure panel 14 is the top gate panel 36, the position of the first closure panel 14 in the second open position is between the position of the first closure panel 14 in the first open position (FIG. 14) and the position of the first closure panel 14 in the closed position (FIG. 6). The first closure panel 14 may move toward the closed position from the first open position to the second open position. In various embodiments, the first closure panel 14 is less open in the second open position than the first open position. In some embodiments, the first closure panel 14 may be substantially fully open in the first open position. It is contemplated that the first closure panel 14 may be operable to be actuated into various positions in addition to the first and second open positions, in some implementations. For example, the first closure panel 14 may be operable to enter a position between the first and second open positions and/or a position between the second open position and the closed position, in some embodiments.

It is contemplated that the controller 92 may prompt movement of the first closure panel 14 to the closed position based on detected precipitation 128, detected precipitation 128 entering the cabin 12, detection of precipitation 128 with a portion of the radar beam 90 that is emitted into the cabin 12 of the vehicle 10, the speed of the detected precipitation 128, and/or the direction of the detected precipitation 128, in various embodiments. Further, it is contemplated that the second closure panel 14 may be operable to move between a plurality of open positions and/or the closed position based on detected precipitation 128, detected precipitation 128 entering the cabin 12, detection of precipitation 128 with a portion of the radar beam 90 that is emitted into the cabin 12 of the vehicle 10, the speed of the detected precipitation 128, and/or the direction of the detected precipitation 128.

Referring now to FIGS. 1, 14 and 15, in an exemplary embodiment, the rear gate assembly 26 of the vehicle 10 includes the top gate panel 36, which is operable to pivot vehicle-downward toward the closed position, and the bottom gate panel 38, which is operable to pivot vehicle-upward toward the closed position. The top gate panel 36 is operable between a first open position, as illustrated in FIG. 14, and a second open position that is nearer to the closed position, as illustrated in FIG. 15. At least one radar sensor 88 is coupled to the top gate panel 36 and is configured to emit the radar beam 90. As illustrated in FIG. 14, the at least one radar sensor 88 is configured to emit a portion of the radar beam 90 into the cabin 12 of the vehicle 10 when the top gate panel 36 is in the first open position. In operation of the exemplary embodiment, precipitation 128 in the form of rain is entering the cabin 12 of the vehicle 10 via the access provided by rear gate assembly 26 when the top gate panel 36 is in the first open position and the bottom gate panel 38 is in the closed position. The at least one radar sensor 88 detects the precipitation 128 with the portion of the radar beam 90 that is emitted into the cabin 12 of the vehicle 10 with the top gate panel 36 in the first open position. Data that indicates the precipitation 128 entering the cabin 12 of the vehicle 10 is transmitted from the at least one radar sensor 88 to the controller 92. The controller 92 prompts movement of the top gate panel 36 from the first open position, as illustrated in FIG. 14, to the second open position, as illustrated in FIG. 15, based on the data received from the at least one radar sensor 88. As illustrated in FIG. 15, the precipitation 128 is blocked from entering the cabin 12 of the vehicle 10 by the top gate panel 36 in the second open position. In various embodiments, moving the top gate panel 36 from the first open position to the second open position, as described herein, may advantageously prevent precipitation 128 from entering the cabin 12 of the vehicle 10, while allowing the top gate panel 36 to remain in an open position.

Referring now to FIGS. 1, 14, and 15, in some embodiments, the vehicle 10 includes first and second closure panels 14. The first closure panel 14 is operable between open and closed positions. The cabin 12 of the vehicle 10 is in fluid communication with the exterior environment 16 of the vehicle 10 with the first closure panel 14 in the open position. The second closure panel 14 is operable between open and closed positions. The cabin 12 of the vehicle 10 is in fluid communication with the exterior environment 16 of the vehicle 10 with the second closure panel 14 in the open position. The sensing system 72 of the vehicle 10 is operable to sense the temperature within the cabin 12 of the vehicle 10. The controller 92 prompts movement of the first closure panel 14 toward the closed position based on the sensed temperature within the cabin 12 exceeding a threshold temperature.

Referring still to FIGS. 1, 14, and 15, in various embodiments, the first closure panel 14 and/or the second closure panel 14 may be one of a variety of types of closure panels 14 of the vehicle 10 (e.g., window, side door, sunroof, etc.). In some embodiments, the first closure panel 14 may form at least a portion of the rear gate assembly 26 of the vehicle 10. For example, the first closure panel 14 may be a single-door lift gate that pivots to the open position to provide access to the rear storage area 20 positioned within the cabin 12 of the vehicle 10. In some embodiments, the second closure panel 14 may form at least a portion of the rear gate assembly 26 of the vehicle 10. In an exemplary embodiment, the first and second closure panels 14 may form portions of the rear gate assembly 26, as described further herein.

Referring now to FIGS. 1, 6, 14, and 15, in some implementations, the first closure panel 14 is operable to pivot a first direction about the first pivot axis 32 away from the closed position, and the second closure panel 14 is operable to pivot a second direction about the second pivot axis 34 away from the closed position, wherein the second direction is opposite the first direction. This is the case in the exemplary embodiment illustrated in FIGS. 1 and 6, wherein the rear gate assembly 26 includes the top gate panel 36 and the bottom gate panel 38 vehicle-downward of the top gate panel 36; the first closure panel 14 comprises the top gate panel 36 and the second closure panel 14 comprises the bottom gate panel 38.

A variety of types of sensors 74 for detecting temperature are contemplated. In some embodiments, the sensing system 72 may be operable to sense sunlight. For example, as described herein, the sensing system 72 may include at least one optical sensor 96 configured to sense sunlight by converting optical energy into an electric signal that is transmitted to the controller 92. In some embodiments, the sensing system 72 is configured to detect sunlight entering the cabin 12 and/or the cargo area 18 of the vehicle 10. For example, the optical sensor 96 may be positioned within the cabin 12 and/or cargo area 18 of the vehicle 10.

Referring now to FIGS. 1, 2, 14, and 15, in various embodiments, the controller 92 may prompt movement of the first closure panel 14 toward the closed position based on the sensed temperature within the cabin 12 of the vehicle 10. In other words, the sensing system 72 may transmit data to the controller 92 pertaining to the sensed temperature within the vehicle 10, and the controller 92 may prompt movement of the first closure panel 14 based on the received data. In some implementations, the controller 92 may prompt movement of the first closure panel 14 toward the closed position based on the sensed temperature within the cabin 12 exceeding a threshold temperature. For example, in some embodiments, wherein the threshold temperature is 80 degrees Fahrenheit, the controller 92 may prompt movement of the first closure panel 14 based on the sensing system 72 sensing a temperature above 80 degrees Fahrenheit within the cabin 12 of the vehicle 10.

Referring still to FIGS. 2, 14, and 15, in some embodiments, the controller 92 may prompt movement of the first closure panel 14 toward the closed position based on the sensed temperature within the cabin 12 of the vehicle 10 and sensed sunlight entering the cabin 12 of the vehicle 10. In an exemplary embodiment, the controller 92 may prompt movement of the first closure panel 14 toward the closed position based on the sensed temperature within the cabin 12 exceeding the threshold temperature and a sensed amount of sunlight exceeding a sunlight amount threshold.

In various embodiments, the controller 92 may prompt movement of the first closure panel 14 from the first open position toward the closed position based on the sensed temperature and/or sunlight within the cabin 12 of the vehicle 10 and terminate movement of the first closure panel 14 at the second open position between the first open position and the closed position. In other words, the controller 92 may prompt movement of the first closure panel 14 toward the closed position and terminate the movement before the closed position is reached. In some embodiments, the controller 92 may prompt movement of the first closure panel 14 toward the closed position based on the sensed temperature and/or sunlight within the cabin 12 of the vehicle 10 and terminate movement of the first closure panel 14 in the closed position. It is contemplated that, in some embodiments, the second closure panel 14 may be operable to move between a plurality of open positions and/or the closed position based on the sensed temperature and/or sensed amount of sunlight within the cabin 12 of the vehicle 10.

Referring now to FIGS. 1, 2, 14, and 15, in an exemplary embodiment, the rear gate assembly 26 of the vehicle 10 includes the top gate panel 36, which is operable to pivot vehicle-downward toward the closed position, and the bottom gate panel 38, which is operable to pivot vehicle-upward toward the closed position. The top gate panel 36 is operable between a first open position, as illustrated in FIG. 14, and a second open position that is nearer to the closed position, as illustrated in FIG. 15. The sensing system 72 of the vehicle 10 includes at least one sensor 74 operable to sense the temperature within the cabin 12 of the vehicle 10, and at least one sensor 74 operable to detect sunlight entering the cabin 12 of the vehicle 10. In operation of the exemplary embodiment, the top gate panel 36 is initially in the first open position, and sunlight is entering the cabin 12 of the vehicle 10 through the rear gate assembly 26 due to the top gate panel 36 being in the first open position. The sunlight entering the cabin 12 of the vehicle 10 raises the temperature within the cabin 12 of the vehicle 10. The sensing system 72 senses the temperature and amount of sunlight within the cabin 12 and transmits corresponding data to the controller 92. The controller 92 determines that the sensed temperature is above the temperature threshold and that the sensed amount of sunlight is above the sunlight amount threshold. In response, the controller 92 prompts movement of the top gate panel 36 toward the closed position from the first open position to the second open position. In the second open position, the top gate panel 36 shades the cabin 12 from the sunlight that was entering the cabin 12 through the rear gate assembly 26 when the top gate panel 36 was in the first open position. Moving the top gate panel 36 to the second open position in this way may advantageously shade the user U and/or another living being L (e.g., dog, cat, etc.) from incoming sunlight when the temperature within the cabin 12 is higher than desired, while keeping the top gate panel 36 partially open to allow for ventilation of the cabin 12 of the vehicle 10.

Referring now to FIGS. 2, 16, and 17, the rear gate assembly 26 may include the first closure panel 14, which may be operable between the open position and the closed position.

For example, the at least one sensor 74 may be the rear imager 78 coupled to the rear gate assembly 26 and configured to collect image data of the exterior environment 16 that is vehicle-rearward of the vehicle 10 where the trailer 130 is positioned while attached to the vehicle 10. In some embodiments, the at least one sensor 74 may include at least one radar sensor 88. The at least one radar sensor 88 may be coupled to the rear gate assembly 26 and configured to emit the radar beam 90 vehicle-rearward into the exterior environment 16 of the vehicle 10 where the trailer 130 is positioned while coupled to the vehicle 10. In the embodiment illustrated in FIG. 16, a plurality of radar sensors 88 are coupled to the top gate panel 36 of the rear gate assembly 26 and cooperate together to form imaging radar, which is used by the controller 92 to determine the proximity of the person relative to at least a portion of the trailer 130, as described further herein. Various types of sensors 74 configured to determine the proximity of the person to the trailer 130 attached to the vehicle 10 are contemplated.

In various embodiments, the controller 92 may prompt execution of the security measure in response to the at least one sensor 74 detecting the person within the predetermined proximity of at least a portion of the trailer 130. In some implementations, the controller 92 may prompt execution of the security measure in response to the at least one sensor 74 detecting the person within the predetermined proximity of any portion of the trailer 130. In some embodiments, the controller 92 may prompt execution of the security measure based on the at least one sensor 74 detecting the person within the predetermined proximity of a tongue 132 of the trailer 130. In some embodiments, the controller 92 may prompt execution of the security measure in response to the at least one sensor 74 detecting the person within the predetermined proximity of a coupler assembly 134 of the trailer 130 and/or one or more components of the coupler assembly 134 (e.g., latch, ball socket, etc.). In an exemplary embodiment, the at least one sensor 74 may detect the person within the predetermined proximity (e.g., three inches) of the coupler assembly 134 of the trailer 130 and transmit the data to the controller 92. The controller 92 may prompt execution of the security measure based on the received data.

Referring now to FIGS. 2, 16, and 17, the controller 92 may be configured to prompt execution of at least one of a variety of types of security measures in response to the at least one sensor 74 detecting the person within the predetermined proximity of at least the portion of the trailer 130. In some embodiments, execution of the security measure may include activation of at least one imager 76 coupled to the vehicle 10. In some embodiments, execution of the security measure may include transmission of an alert to the portable electronic device 56. For example, the controller 92 may transmit an alert signal to the smartphone of the user U, which may emit an audible, tactile, and/or visual alert in response. In some implementations, execution of the security measure may include emission of an audible alert by the vehicle 10. The sound source device 52 of the vehicle 10 may emit the audible alert.
