The present invention relates generally to a vehicular vision system for a vehicle and, more particularly, to a vehicular vision system that utilizes one or more cameras at a vehicle.
Use of imaging sensors in vehicle imaging systems is common and known. Examples of such known systems are described in U.S. Pat. Nos. 5,949,331; 5,670,935 and/or 5,550,677, which are hereby incorporated herein by reference in their entireties. Use of imaging sensors in vehicular trailer assist systems is common and known. Examples of such known systems are described in U.S. Pat. Nos. 9,446,713 and 9,085,261, which are hereby incorporated herein by reference in their entireties.
A driving assistance system or vision system or imaging system for a vehicle utilizes one or more cameras (preferably one or more CMOS cameras) to capture image data representative of images exterior of the vehicle, and provides control of a tailgate of the vehicle to limit or preclude fully opening the tailgate when a hitch (including a hitch ball mounted at an extending portion that is configured to be partially received at a hitch receiver of the vehicle) is attached at the hitch receiver of the vehicle. The camera is disposed at a rear portion of the vehicle and captures image data. The tailgate of the vehicle is openable along a downward swing path of the tailgate. An image processor processes image data captured by the camera to detect presence of objects in the field of view of the camera. The image data captured by the camera is processed by the image processor to detect presence of the hitch attached at a hitch receiver of the vehicle or to detect presence of an object behind the vehicle that may interfere with opening of the tailgate. The vehicular vision system, responsive to detection of the hitch attached at the hitch receiver of the vehicle and/or detection of the object that may interfere with opening of the tailgate, limits opening of the tailgate of the vehicle.
These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.
A vehicle vision system and/or driver or driving assist system and/or object detection system and/or alert system operates to capture images exterior of the vehicle and may process the captured image data to display images and to detect objects at or near the vehicle and in the predicted path of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a forward or rearward direction. The vision system includes an image processor or image processing system that is operable to receive image data from one or more cameras and provide an output to a display device for displaying images representative of the captured image data. Optionally, the vision system may provide display, such as a rearview display or a top down or bird's eye or surround view display or the like.
Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle 10 (such as a pickup truck with a tailgate 10a) includes an imaging system or vision system 12 that includes at least one exterior viewing imaging sensor or camera, such as a rearward viewing imaging sensor or camera 14 (and the system may optionally include multiple exterior viewing imaging sensors or cameras, such as a forward viewing camera at the front (or at the windshield) of the vehicle, and a sideward/rearward viewing camera at respective sides of the vehicle), which captures images exterior of the vehicle, with the camera having a lens for focusing images at or onto an imaging array or imaging plane or imager of the camera (
As shown in
Optionally, the system may also be operable to detect presence of an aftermarket step (or other attachment) at the rear bumper of the vehicle (or such as attached at the hitch receiver of the vehicle) that may be in the path of the tailgate if the tailgate is fully opened/lowered. Thus, the same function can work for aftermarket products (e.g., detection of a hitch receiver-mounted pickup bed step, a bike rack received at the hitch receiver or other attachment). In such an application, the bed step or bike rack (or other attachment) is inserted into the hitch receiver. If the bed step or bike rack (or other attachment) is large enough so as to encroach into the swing path of the tailgate, the system will limit or disable opening of the tailgate. However, such aftermarket steps or attachments may have small enough profiles such that they would not encroach into the tailgate swing path. In such an application, the system, which knows the position of the step or other sufficiently small attachment (via image processing of image data captured by the camera) and the tailgate swing path, would allow the tailgate to be fully opened.
Furthermore, the system may be operable to detect presence of an object at or near the rear of the vehicle that is not attached to the hitch, such as a wall or stationary object like a fire hydrant or pile of bricks or a moving object like a pedestrian or animal. In response to detecting presence of the object at or near the rear of the vehicle, the system may determine if the object is within the swing path of the tailgate 10a (i.e., the path along which the tailgate moves between its closed position and its opened position). If the detected object is determined to be in or near the swing path of the tailgate, the system limits or prevents movement of the tailgate 10a from the closed position toward the opened position, such as by preventing release of the latch mechanism to retain the tailgate 10a in the closed position or by limiting movement of the tailgate 10a along the swing path. In other words, other objects that could potentially damage the tailgate or lift gate are considered, including objects that are not attached to the hitch (e.g., a fire hydrant, a bike rack, a pile of bricks sitting on the ground yet in the path of travel of the gate, and the like). That is, the other object detected by the system does not need to be something attached to the hitch 20. Thus, if the driver performs a reversing maneuver and backs the vehicle close to the fire hydrant or other object that is tall enough to interfere with the tailgate travel, the camera may detect the interference condition and restrict or prevent tailgate travel.
The system thus provides a smart rear camera with object detection features capable of identifying a hitch or other object (e.g., a fire hydrant or pile of bricks) in the path of the opening tailgate. The system knows the path of the tailgate relative to the camera (which may be a dedicated camera for this system or may be the rear backup camera of the vehicle or other rearward viewing vehicle camera that includes at least a portion of an attached hitch in its field of view) and can determine if a detected object (e.g., the attached hitch) is in the path of travel of the tailgate. The system or processor or camera identifies if an object or hitch is in the path of the tailgate or tailgate subsystem and the system may interlock or limit or control the tailgate opening process. That is, full tailgate deployment is disabled when the system determines that the hitch or step or other object is in the path of travel of the tailgate when the tailgate opens.
The camera may comprise a camera and object detection software for processing image data captured by the camera. Optionally, the camera may comprise a smart camera that is capable of running the “hitch detection” or “obstruction in tailgate path” software.
During operation (such as when the vehicle is not moving and when opening of the tailgate is attempted), the camera or system detects an object in the tailgate path either before or immediately upon tailgate opening action. Responsive to determination of presence of the hitch (or other object) in the tailgate opening path, the system activates an interlock in the tailgate opening controls. For example, the system may actuate a mechanical interlock that limits or stops or precludes opening movement of the tailgate, such as limiting releasing the tailgate to start opening or stopping downward movement of the tailgate at a location above the hitch. Optionally, the system may control electronic control movement of the tailgate to limit opening of an automatic or powered tailgate. That is, the system may control powered opening of the tailgate based on the detected object and the determined position of the object relative to the tailgate.
The system may operate to detect the hitch and to control or limit opening of the tailgate responsive to actuation of a release handle of the tailgate (or actuation of a control for powered opening of the tailgate). The system, responsive to detection of the hitch when the tailgate is being opened (or at commencement of opening of the tailgate), may limit opening movement and/or may generate an alert to the operator, who may be at the rear of the vehicle (whereby the alert may comprise an audible alert or a flashing light at the tailgate) or in the vehicle cabin (whereby the alert may comprise an audible alert or a flashing light in the cabin or a visual alert at a video display in the cabin that is viewed by the operator).
The tailgate travel path is known in advance. Knowledge of this path and awareness of the hitch (or other object) location is used to determine in advance if a collision will occur between the tailgate and the hitch (or other object). The system can lock out the secondary tailgate travel to limit or stop movement of the tailgate to avoid the collision and prevent damage to the tailgate. In other words, the system may have the tailgate travel path stored in memory and, in determining to limit opening of the tailgate, the system may compare the determined position of the detected object to the known travel path.
Because the camera 14 may be disposed at the tailgate 10a and thus move with the tailgate 10a as the tailgate moves between the closed position and the opened position, determination of whether the detected object is in the path of the tailgate may occur before the tailgate is permitted to move from the closed position to ensure accuracy of the object detection. For example, when the tailgate 10a is in the closed position, the relative position of the camera 14 to the object may be easier to determine than when the tailgate 10a and camera are moving toward the opened position and thus toward the object. Optionally, in response to detecting the object in the captured image data and before the user requests to open the tailgate (e.g., grasps the handle at the tailgate or actuates the input at the keyfob or interior of the vehicle), the system may determine if the object is within the opening path of the tailgate 10a to more quickly react (e.g., prevent opening of the tailgate) when the user requests to open the tailgate.
The system may also capture image data during a reversing maneuver of the vehicle to determine if a trailer hitch is attached at the hitch receiver and to determine if the hitch may impact an object (e.g., another vehicle, a garage wall, a pile of bricks, and the like), rearward of the vehicle during the reversing maneuver. By determining the rearward-most extended position of the hitch, the smart camera may also apply automatic braking or generate an alert (e.g., sound an alarm or display a warning at the vehicle display) prior to collision.
Optionally, the system may use the determined hitch location information to change a sensing range of an ultrasonic sensor system of the vehicle. For example, if the camera detects that the hitch (or other attachment) extends a certain distance beyond the rear bumper of the vehicle, the camera or system can inform the ultrasonic sensing system of the vehicle (via the CAN bus) to adjust the warning zone (the rearward distance at which warning tones or visual warnings are generated when an object is detected rearward of the vehicle) outward by that same distance. The benefit is a reduced likelihood of backing the hitch into another vehicle, a wall, or some other barrier (when the ultrasonic sensing system functions as if the rear bumper is the rearward-most part of the vehicle).
The system thus prevents damage to the tailgate, the hitch, objects attached to the hitch and/or other objects rearward of the vehicle and provides enhanced customer satisfaction. The system may utilize the rear camera of the vehicle that is already installed at the vehicle (e.g., the rear backup camera or other rearward viewing camera of the vehicle).
Therefore, during a reversing maneuver of the vehicle (such as responsive to the vehicle shifting into a reverse gear or reverse propulsion), the rear backup camera operates to capture image data during reversing of the vehicle, whereby image data captured by the rear backup camera is processed for display at a display screen of video images for viewing by the driver during the reversing maneuver and is processed for object detection. When the vehicle is powered, and when the rear backup camera operates and views the hitch ball (which, when mounted at the hitch receiver, extends rearward of the rear bumper of the vehicle, such as by, for example, 4 inches, or 6 inches, or 8 inches or more), the system determines when the hitch ball is present and in the downward swing path of the tailgate. Responsive to determining that the hitch ball is present and in the downward swing path of the tailgate, the system outputs a message on a CAN bus (controller area network) of the vehicle, which generates a signal to the tailgate opening system to disable the tailgate latch from being released and to keep the tailgate from opening (or optionally to allow the tailgate to partially open but limiting its downward travel to a location or orientation that avoids impact with the hitch ball). The system may also convey a message to the operator (such as at the video display screen in the vehicle or to a screen or indicator at the rear of the vehicle) to alert the operator that the tailgate release mechanism has been disabled.
The system may utilize any suitable camera, such as the existing rear backup camera of the vehicle or other rearward viewing camera at the vehicle. For example, the camera (e.g., the rear backup camera) may comprise a RIO Camera provided by Magna Electronics Inc. of Auburn Hills, Michigan. As shown in
The camera 14 may comprise a smart camera that includes processing circuitry, such as the multi-core processor (digital signal processing (DSP) and advanced reduced instruction set computer (RISC) machine (ARM)), and machine vision algorithms may run on the multi-core processor. The camera may provide ISP support and high dynamic range with local tone mapping. A powerful spatial transform engine may provide flexible viewing mode design. Thus, the camera 14 provides a single unit that may provide the features and performance of a system that would typically require the camera and a separate ECU. The camera may include a metal housing for better thermal management. Further, the camera 14 may provide a relatively small size cross-section (such as a front size of about 23 millimeters by 23 millimeters and a rear size of about 23 millimeters by 28 millimeters).
The camera 14 includes a front housing portion or lens holder 22 having an aperture that accommodates a lens barrel 24 that includes one or more lens or optic elements. In the illustrated example of
An imager printed circuit board (imager PCB) 28 includes an imager and is disposed at the lens holder 22 such that the imager is aligned with the lens barrel assembly 24. A connector printed circuit board (connector PCB) 30 is electrically connected to the imager PCB and is disposed at an opposite side of the imager PCB 28 from the imager. A header connector 32 is disposed on the opposite side of the connector PCB 30 from the imager PCB 28 and is configured to connect to a six-way connector 34 disposed in a connector portion 26a of the rear housing 26 when the front and rear housings are joined together. The connector 34 may be disposed at the connector portion 26a of the rear housing 26 with an O-ring seal or gasket circumscribing the connector 34 to preclude entrance of moisture or contaminants into the camera housing. A thermal pad or other suitable thermal element 36 may be disposed at a rear surface of the rear housing 26 and engage the connector PCB 30 to help dissipate heat from the two-board stack and through the metal rear housing 26 of the camera 14. One or more screws or other suitable threaded fasteners 38 may extend through the front housing 22, the imager PCB 28, the connector PCB 30 and be received at threaded receivers of the rear housing 26 to join the camera components together.
The system may utilize aspects of the door control systems described in U.S. Pat. Nos. 11,124,113 and/or 9,068,390, and/or U.S. Publication No. US-2022-0227366, which are all hereby incorporated herein by reference in their entireties.
The camera or sensor may comprise any suitable camera or sensor. Optionally, the camera may comprise a “smart camera” that includes the imaging sensor array and associated circuitry and image processing circuitry and electrical connectors and the like as part of a camera module, such as by utilizing aspects of the vision systems described in U.S. Pat. Nos. 10,099,614 and/or 10,071,687, which are hereby incorporated herein by reference in their entireties.
The system includes an image processor operable to process image data captured by the camera or cameras, such as for detecting objects or other vehicles or pedestrians or the like in the field of view of one or more of the cameras. For example, the image processor may comprise an image processing chip selected from the EYEQ family of image processing chips available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and may include object detection software (such as the types described in U.S. Pat. Nos. 7,855,755; 7,720,580 and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver's awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle.
The vehicle may include any type of sensor or sensors, such as imaging sensors or radar sensors or lidar sensors or ultrasonic sensors or the like. The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, a two dimensional array of a plurality of photosensor elements arranged in at least 640 columns and 480 rows (at least a 640×480 imaging array, such as a megapixel imaging array or the like), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. The imaging array may comprise a CMOS imaging array having at least 300,000 photosensor elements or pixels, preferably at least 500,000 photosensor elements or pixels and more preferably at least 1 million photosensor elements or pixels arranged in rows and columns. The imaging array may capture color image data, such as via spectral filtering at the array, such as via an RGB (red, green and blue) filter or via a red/red complement filter or such as via an RCC (red, clear, clear) filter or the like. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data.
