Automated vehicles are developed to automate, adapt, or enhance vehicle driving capabilities with limited human intervention. When parking, automated driving vehicles can maneuver into a designated parking space, drive around continuously, or return home. In populated areas, the majority of the curbs and side streets appear available as parking spaces to the sensors attached to the automated vehicles, but are actually unavailable for parking due to the ingress and egress access points from buildings or structures that must be kept clear or due to parking signage, hazard zones, or private property. These impermissible parking areas must remain freely accessible in order for cars, trucks, and other moving objects to move in and out of the designated area.
To easily identify the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced.
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of some example embodiments. It will be evident, however, to one skilled in the art that the present disclosure may be practiced without these specific details.
As the rise in automated driving vehicles become increasingly popular, automated vehicles can now fully drive themselves without human interaction. Automated driving vehicles (ADVs) have no need to park close to their destination, or even permanently park at all. Instead, ADVs can seek out free on-street parking, return home, or cruise (circle around). The suggested course of action here is to modernize the idea of parking to also include empty cruise time. These solutions do not resolve issues of energy consumption and road congestion by the ADVs as they cruise around various areas while searching (or idling) for a parking space.
In both rural and urban areas, empty spaces that are not officially designated as available parking spaces can in fact be utilized as temporary parking spaces for ADVs. These empty spaces include curbs and side streets that intersect with a driveway, walkway, or pathway and also, open areas that have been designated as “non-parking” by an authorized parking official, municipality, or private property owner. For curbs and side streets that intersect with a driveway, walkway, or pathway, the issue arises when the ADV parks in an unavailable parking space, the ADV obstructs the exit or entrance of moving objects, such as cars, motorcycles, bicycles, or any other objects, essentially restricting the flow of the moving objects and preventing them from exiting or entering an area due to the parked ADV blocking the passage of the driveway.
In at least one example, a system is provided that enables an ADV to unilaterally identify an empty space, that may or may not be available, on a roadway and instruct the ADV to park into the parking space and drive away from the parking space when moving objects approach. For instance, using on-board sensors, the system verifies the physical dimensions of the curb, the roadway marker on the roadway, the curb type, parked vehicles and other structural characteristics within the vicinity of the empty space, and when the empty space has been verified, the system autonomously parks the ADV into the empty space, which can be in front of a driveway meant for ingress and egress by other vehicles. While the ADV is parked in the empty space, the system identifies when another vehicles, objects, or moving objects are approaching and immediately reacts by moving the ADV out of the empty parking space in order to allow the moving object to enter or exit the driveway.
In another example, the system can communicate with a central management platform application in order to determine which parking spaces within a selected area have been designated as available and/or unavailable parking spaces. The system uses the information from the central management platform to identify places and hours where the ADV can park and autonomously move away based on the information. In another example, while the ADV is parked in the empty space, the system can also receive requests from other vehicles, such as non-ADVs, governmental vehicles, or emergency vehicles, to vacant the empty space based on detecting hazard lights, headlight flashes, and other traffic indicators emitted from the approaching vehicle.
The ADV 102 may operate at in a manual mode where the driver operates the ADV 102 conventionally using pedals, including the brake pedal and acceleration pedal, steering wheel, and other controls. At other times, the ADV 102 may operate in a fully autonomous mode (e.g., the ADV 102 operating without user intervention). In addition, the vehicle 104 may operate in a semi-autonomous mode (e.g., where the vehicle 104 controls many of the aspects of driving, but the driver may intervene or influence the operation using conventional steering wheel and non-conventional inputs such as voice control).
The ADV 102 includes a sensory array interface 104, which may include various forward, side, and rearward facing cameras, radar. LIDAR, ultrasonic, or similar sensors. Forward-facing is used in this specification to refer to the primary direction of travel, the direction the seats are arranged to face, the direction of travel when the transmission is set to drive, or the like. Rear-facing or rearward-facing is used to describe sensors that are directed in a roughly opposite direction than those that are forward or front-facing. It is understood that some front-facing camera may have a relatively wide field of view, even up to 180-degrees.
Similarly, a rear-facing or front facing camera that is directed at an angle (perhaps 60-degrees off center) to be used to detect traffic or approaching vehicles in adjacent traffic lanes or within the vicinity of the ADV 102, may also have a relatively wide field of view, which may overlap the field of view of the front-facing camera. Side-facing sensors are those that are directed outward from the sides of the vehicle. Cameras in the sensor array may include infrared or visible light cameras, able to focus at long-range or short-range with narrow or large fields of view.
Further, the ADV 102 includes an on-board diagnostics system to record vehicle operation and other aspects of the vehicle's performance, maintenance, or status. The ADV 102 may also include various other sensors, such as driver identification sensors (e.g., a seat sensor, an eye tracking and identification sensor, a fingerprint scanner, a voice recognition Module, or the like), occupant sensors, or various environmental sensors to detect wind velocity, outdoor temperature, barometer pressure, rain/moisture, or the like.
Components of the occlusion prevention subsystem 108 may communicate using a network, which may include local-area networks (LAN), wide-area networks (WAN), wireless networks (e.g., 802.11 or cellular network), the Public Switched Telephone Network (PSTN) network, ad hoc networks, personal area networks (e.g., Bluetooth), vehicle-based networks (e.g., Controller Area Network (CAN) BUS), or other combinations or permutations of network protocols and network types. The network may include a single local area network (LAN) or wide-area network (WAN), or combinations of LANs or WANs, such as the Internet. The various devices coupled to the network may be coupled to the network via one or more wired or wireless connections.
In operation, the ADV 102 detects sensory information via sensory array interface 104 from forward-facing sensors to detect an object, moving object, structural characteristics, traffic signage, road markings, curb types, curb dimension information, or potential collision hazard. The forward-facing sensors may include radar, LIDAR, visible light cameras, or combinations. Radar is useful in nearly all weather and longer range detection, LIDAR is useful for shorter range detection, cameras are useful for longer ranges but often become less effective in certain weather conditions, such as snow. Combinations of sensors may be used to provide the widest flexibility in varying operating conditions.
In one example, based on the sensory information, a processor 106 integrated in the occlusion prevention subsystem 108 includes machine learning algorithmic programming that enables the system to detect an empty space, such as a parking space with a curb and size and space dimensions, detect roadway markers associate with the parking space, determine that the parking space is available or unavailable based on the roadway markers, execute plausibility checks (discussed below), determine whether a possible collision may occur, instruct communication with a third party application, such as a centralized platform, identify and detect approaching objects. Based on this determination, the occlusion prevention subsystem 108 may initiate braking of the ADV 102 and/or automated guiding into the parking space by utilizing the brake 110 and acceleration operations of the brake 110 and accelerator 112. The processor 106 interfaces with interrupt controller 114, brake 110, and accelerator 112 to initiate autonomous detection and moving of the ADV 102 according to the configuration of the occlusion prevention subsystem 108.

As such, the wireless communication controller 118 may be a 4G or 5G wireless controller or other radio-based controller to support vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-anything (V2X), or other types of communication. The wireless communication controller 118 may be in communication with other vehicles on the roadway, a centralized platform application, cloud-based databases, or other static installations, such as radio towers, roadside monitors, smart traffic lights, or emergency personnel.
In one example, the camera VPU 120 is used to detect, capture, and analyze images, content, structures, objects, vehicles, and other imagery detected from one or more forward-facing, side-facing, or backward-facing cameras. When the camera VPU 120 is used to detect, capture, and/or analyze an empty space, a moving object approaching the ADV 102, structural characteristics, a roadway marker, a general hazard in the road or other potential hazard, or a traffic indicator, the wireless communication controller 118 asserts one or more specific interrupts to signal the interrupt controller 114. As one or more interrupts are asserted, the processor 106 reads status registers or memory (e.g., from memory 116), to obtain further information about the interrupt. The processor 106 executes rules and routines to determine an appropriate response.
In some examples, responses include, but are not limited to, guiding the ADV 102 into a parking space, initiating an application of brakes with a braking force, initiating an actuated force of acceleration of the ADV 102 and guiding the ADV 102 in the direction away from the parking space, alerting a driver of the ADV 102 of the unavailability of a parking space or incapability of the parking space dimensions for the ADV 102. In one example, the actuated force of acceleration represents automatically or autonomously activating the accelerator 112 and other structural components of the ADV 102 to drive, move, guide, and accelerate the ADV 102 in a direction. In another example, initiating an application of brakes represents applying the ADV 102 parking brake 110. The braking force represents the force applied to the brake 110 by a driver (if in manual mode) or autonomously (e.g., by the ADV 102 to autonomously slow or stop the vehicle). Additionally, the processor 106 may transmit a signal using the wireless communication controller 118 to receive traffic and parking space availability and unavailability information from the centralized platform application.
In another example, the occlusion prevention subsystem 108, upon activation, detects a moving object approaching from a direction toward the automated driving vehicle. The moving object includes a heading as described above. The occlusion prevention subsystem 108 determines that the heading of the moving object is pointing toward the automated driving vehicle, along with a distance between the moving object and the automated driving vehicle. If the distance between the moving object and the automated driving vehicle is less than the threshold value, the occlusion prevention subsystem 108 initiates an actuated force of acceleration of the automated driving vehicle and guides the automated driving vehicle in the direction away from the available space. For example, the occlusion prevention subsystem 108 moves the vehicle out of the available space or away from the available space.

The phrase “realistic trajectory” represents the angle in which the approaching vehicle 202 can reasonable use to turn into a parking space, structural characteristic, or empty space based on the location of the ADV 102 and the length of the approaching vehicle 202, the size of the approaching vehicle 202, and the speed of the approaching vehicle 202. The evaluation of the corridor angle trajectory that an approaching angle of the vehicle will converge to 90 in relation to the main driving direction of the road in order to minimize time and distance for crossing the road. As shown in
In another example, the valid corridor angle trajectory 404 represents a turning diameter orthogonal to a 90° angle associated with the automated driving vehicle. Once the ADV 102 determines that the corridor angle trajectory 404 is valid, the occlusion prevention subsystem 108 initiates the actuated force of acceleration of the ADV 102. The occlusion prevention subsystem 108 also determines invalid corridor angle trajectory 402. After determining invalid corridor angle trajectory 402, the occlusion prevention subsystem 108 instructs the ADV 102 to remain parked or in a static (e.g., still) state. In another example, after determining invalid corridor angle trajectory 402, the occlusion prevention subsystem 108 instructs the ADV 102 to initiate an application of brakes with the braking force.
The method commences with operation 502, during which the occlusion prevention subsystem 108, via the sensory array interface 104, detects a parking space, the parking space includes a curb and a space dimension. The space dimensions represents space characteristics including the width, length, and depth dimensions of the parking space. As with a parking space, an open area, empty space, or the like can also be detected. In another example, the space dimension is an area that is larger than the ADV 102.
In operation 504, the occlusion prevention subsystem 108 detects a roadway marker associated with the parking space. In one example, the roadway marker is a visual layout overlaid on the roadway representing a combination of words, shapes, or polygonal arrangements that indicate available and non-available parking spaces. The roadway marker can also include road markings associated with a permissible parking space, a series of signs, and various forms of signage within the proximity of the detected parking space. In operation 506, the occlusion prevention subsystem 108 determines that the parking space is available based on the roadway marker and the space dimension.
The sensory array interface 104 verifies the suitability of an empty parking space or area for parking by recognizing the dimensions of the parking space, parked vehicles within the immediate vicinity of the parking space, walkways and pathways around the parking space, the curb type, and other structural characteristics within the vicinity or area near the detected parking space. In response to determining that the parking space is available based on the roadway marker and the space dimension, the occlusion prevention subsystem 108 continues with operation 508, in which the occlusion prevention subsystem 108 guides the automated driving vehicle into the parking space and initiates the application of brakes with the braking force (e.g., parks the car into the parking space).
In some examples, the occlusion prevention subsystem 108 communicates with a computing device and retrieves and transmits the parking space characteristics to the computing device. The computing device includes a third party server or client computing device integrated into an automated driving vehicle. In one example, the occlusion prevention subsystem 108 communicates with a centralized management platform application (e.g., MOOVIT®) in order to retrieve space availability information and parking space occupancy data representing the specified area, time, and location of parking spaces or empty spaces that a non-automated vehicle (or automated vehicle) is prohibited from using. For instance, a parked vehicle or a house owner may input to the platform that his vehicle or garage entrance is typically not used from 9:20 am until 4:30 pm. Automated vehicles may then use this service to identify places and hours where they could park and autonomously move away if needed (in-front of garage or in 2nd row). The occlusion prevention subsystem 108 receives parking space occupancy data, from the computing device, based on the parking space characteristics and determines that the parking space is unavailable based on the parking space occupancy data. In response determining that the parking space is unavailable, the occlusion prevention subsystem 108 guides the automated driving vehicle in a direction away from the parking space.
In another example, after detecting an available parking space, the processor 106, after receiving user input, transmits and registers the parking space occupancy data with a third party application stored on a third party computing device, e.g., MOOVIT®, as well as, space registration information regarding the available parking space. In one example, space registration information represents the specified area, time, dimensions, and location of parking spaces or empty spaces that a non-automated vehicle (or automated vehicle) is prohibited or allowed to use.
The processor 106 determines, via the sensory array interface 104, if the detected parking space is occupied 608 by another vehicle or object. If the detected space is occupied, the processor 106 instructs the ADV 102 via the accelerator 112 and brake 110 to exit 610 (e.g., guide or drive away from the occupied space). If the processor 106, via the sensory array interface 104 or based on receiving parking space occupancy data from the third party application, determines that the parking space 608 is not occupied 612, the processor 106 determines if the space is permanently unavailable 614.
As further shown in
Upon detecting a parking space 704, the processor determines signage 706, roadway markers 708, and parking space availability 710. In one example, the roadway marker is a visual layout overlaid on the roadway representing a combination of words, shapes, or polygonal arrangements that indicate available and non-available parking spaces. The roadway marker can also include road markings associated with a permissible parking space, a series of signs, and various forms of signage within the proximity of the detected parking space. The signage represents traffic signs, banners, illustrations, or traffic imagery that indicates available or unavailable parking spaces, hazards, or road conditions, roadway markers also include a unique symbol indicating that the ADV 102 can move away autonomously, a machine readable code (e.g., barcode or QR image), or cleartext instructions directed to how to approach and signal the ADV 102 to move into the available parking space.
The processor 106 includes specialized circuit which includes a tarmac signage detection algorithm based on a machine learning algorithm specifically designed to recognize new road markings and detect explicitly allowed parking locations. At decision block 712, if roadway markers are detected, the processor 106 determines whether the ADV 102 is prohibited from parking in the detected space via the processes utilizing the sensory array interface 104 as discussed above or by communicating with the third party application. e.g., centralized management platform. In decision block 714, if the ADV 102 is prohibited from using the parking space, the ADV 102 will continue to drive in search for another available parking space.
If the ADV 102 is permitted to use the parking space, it is considered a free space detected 716 and the ADV 102 is instructed via the processor 106 to slow down and activate the turn signal 720. Upon executing decision block 720, the ADV 102 slowly passes and captures parking space dimensions. e.g., width, length, depth of the parking space 722. If the ADV 102 determines, via the processor 106 and sensory array interface 104 that the parking space dimensions do not correspond with the size of the ADV 102, the ADV 102 will continue to drive in search for another available parking space. If the ADV 102 determines, via the processor 106 and sensory array interface 104, that the parking space dimensions correspond with the size of the ADV 102, the processor 106 executes a plausibility check algorithm.
The plausibility check algorithm is based on a machine learning algorithm and is designed to determine the structural characteristic of the area surrounding or within the immediate vicinity of the parking space (block 728), the curb type and size (block 730), and vehicles parked within the vicinity of the detected parking space (block 732). A free-space detection algorithm is further utilized to detect vehicles that are just about to approach or leave through the detected curb type.
In one example, the plausibility check machine learning algorithm is designed to recognize the appearance of different exits and entrances from buildings, stores, schools, or compounds (structural characteristics). A measurement algorithm using data from the sensory array interface 104 detects the depth measurements (e.g., radar. LIDAR, stereo cameras, or a combination thereof) to identify the shape of the curb. The curb type that is determined by the plausibility check 726 corresponds to detecting an exit curb type, an intersection curb type, or standard undecided curb type. An exit curb type is assigned a strong confidence score (e.g., value), e.g., 10. An intersection curb type is assigned a medium confidence score, e.g., 5. A standard or undecided curb type is assigned a low confidence score, e.g., 1.
The processor 106 combines (block 734) or aggregates the results of each allocated confidence score determined from the detected curb types generated by the plausibility check 726. If the confidence score is high (block 736) and above a predetermined threshold, the ADV 102 will park 738 and activate the brake 110 and stop (block 740). The predetermined threshold can be a confidence score of 5 or higher. In another example, if the confidence score is 10 or greater and there is no detection of another vehicle parked within the vicinity of the ADV 102, the processor 106 will instruct the ADV 102 to park. If the confidence score is low (block 736) and below a predetermined threshold, the ADV 102 will continue driving 718.
