Embodiments of the present disclosure relate to vehicle detection and, in particular, to vehicle detection and identification subject to an emergency alert.
Self-driving or otherwise autonomous vehicles require the ability to be able to detect one or more objects and/or potential hazards within the environment of the vehicle in order to safely and efficiently navigate the environment and prevent possible collision. These vehicles include detection mechanisms (e.g., cameras, radar, LiDAR, etc.) configured to enable these vehicles to perform these functions.
In addition to detecting these objects, the detection mechanisms could be programmed to detect identifiable features (e.g., license plate number, color, make, model, etc.) of one or more objects in order to not only detect the objects, but also to identify the objects based on these one or more detected identifiable features.
Identifying objects (e.g., identifying a particular vehicle) can be used to help authorities track down certain vehicles for one or more investigative purposes. For example, in the event of an emergency alert (e.g., an Amber Alert), the detection mechanisms of a self-driving or otherwise autonomous vehicle may be used to image the license plate of a vehicle in order to determine if the vehicle matches a vehicle description identifies in the emergency alert.
However, privacy concerns make reading license plates from an autonomous vehicle a contentious issue, given that drivers may feel that giving autonomous vehicles carte blanche to analyze all identifiable features for every vehicle within the environment of the autonomous vehicle is a violation of privacy.
For at least these reasons, systems and methods are needed to enable autonomous vehicles to identify vehicles in the event of an emergency alert, taking into account the urgency of emergency alerts, while increasing protections of privacy for vehicles not identified within the emergency alert.

The analyzing includes, for each character of the license plate 160 of the detected vehicle 155, determining the character of the license plate 160 of the detected vehicle 155, and determining whether the character of the license plate 160 of the detected vehicle 155 matches a respective character of the license plate of the wanted vehicle. According to various embodiments, when the character of the license plate 160 of the detected vehicle 155 matches the respective character of the license plate of the wanted vehicle, and when there is a subsequent character of the license plate 160 of the detected vehicle 155, the license plate 160 of the detected vehicle 155 is analyzed for the subsequent character. According to various embodiments, when the character of the license plate 160 of the detected vehicle 155 does not match the respective character of the license plate of the wanted vehicle, the analyzing of the license plate 160 of the detected vehicle 155 ends.
The vehicle 105 may include a vehicle detection and identification system 200 as shown, for example, in
According to various embodiments, the vehicle detection and identification system 200 may include one or more detection mechanisms (e.g., one or more cameras 125) configured to capture one or more images of the autonomous vehicle's surrounding environment, one or more location detection systems 145, and/or one or more transceivers 165. The vehicle detection and identification system 200 may include an emergency alert module 205 configured to analyze one or more images captured by the one or more cameras 125.
The emergency alert module 205 may include one or more color detection modules 210, configured to detect and/or determine one or more colors of a detected vehicle 155 based on the input from the one or more detection mechanisms, one or more make/model detection modules 215, configured to detect and/or determine the make and/or model of a detected vehicle 155 based on the input from the one or more detection mechanisms, one or more plate reader modules 220, configured to detect and/or determine a location associated with a license plate 160 of a detected vehicle 155 and/or one or more characters of the license plate 160 of a detected vehicle 155, and/or other suitable vehicle identification modules. The emergency alert module 205 may be contained within and/or in electronic communication with the one or more computing devices 130. According to various embodiments, the emergency alert module 205 is in an off state until an active emergency alert is received.
The emergency alert may be generated and sent via a wireless emergency alert system 300 as shown, e.g., in
The wireless emergency alert system 300 may be configured to receive and/or generate an emergency alert, and may be configured to send the emergency alert, via, e.g., a central dispatch 305, to one or more appropriate autonomous vehicles (e.g., AVs 105a, 105b, 105c, 105d, and 105e). The central dispatch 305 and the one or more appropriate autonomous vehicles (e.g., AVs 105a, 105b, 105c, 105d, and 105e) may be configured to communicate with each other, enabling a transfer of information to and from the central dispatch 305 and the one or more appropriate autonomous vehicles (e.g., AVs 105a, 105b, 105c, 105d, and 105e).
According to various embodiments, the wireless emergency alert system 300 may be configured to determine the appropriate autonomous vehicles based on a geographic location/region of each vehicle as compared to the geographic location/region designated by the emergency alert, thereby only relaying the emergency alert to vehicles that are located within the geographic location/region designated by the emergency alert.
According to various embodiments, upon receiving the emergency alert, a state of an autonomous vehicle's emergency alert module 205 is set to an on state, enabling the autonomous vehicle to analyze one or more vehicles within the surrounding environment of the vehicle in order to determine if the wanted vehicle is within the surrounding environment of the autonomous vehicle.
According to various embodiments, when a vehicle (e.g., AVs 105a, 105b, 105c, 105d, and/or 105e) makes a positive identification for a wanted vehicle, the identification can be sent, from the vehicle, back to the central dispatch 305 to send a response to one or more appropriate agencies and/or authorities 310 that are responsive to the emergency alert. The wireless emergency alert system 300 may be configured to generate and/or send (via, e.g., the central dispatch 305) one or more inactive commands to all vehicles (e.g., AVs 105a, 105b, 105c, 105d, and/or 105e) that were otherwise active in the search. According to various embodiments, once an autonomous vehicle receives an inactive command, the state of the autonomous vehicle's emergency alert module 205 is set to an off state.
According to various embodiments, once a positive identification of the wanted vehicle is made, the wireless emergency alert system 300 may be configured to generate and/or send (via, e.g., the central dispatch 305), a command to remain active to any vehicles within a geographic region of the positively identified vehicle until receiving a subsequent inactive command.
According to various embodiments, the central dispatch 305 may comprise one or more processors 135, memory 140, transceivers 165, user interfaces, displays, and/or other suitable components. The transceiver 165 may be configured to receive a positive identification signal generated from an autonomous vehicle, the positive identification signal indicating that a wanted vehicle has been positively identified. The memory 140 may be configured to store programming instructions that, when executed by the processor 135, cause the processor 135 to identify a location of the autonomous vehicle, locate one or more other autonomous vehicles that are searching for the wanted vehicle, subject to an emergency alert, and generate, using the processor 135, and/or send, by the transceiver 165, a search halt command to some or all of the one or more other autonomous vehicles searching for the wanted vehicle, the search halt command configured to cause the one or more other autonomous vehicle to cease a search for the wanted vehicle.
According to various embodiments, the transceiver 165 may be further configured to receive velocity information regarding the wanted vehicle. The programming instructions, when executed, may be further configured to cause the processor 135 to determine which of the one or more other autonomous vehicles are less than a threshold distance from the autonomous vehicle that generated the positive identification signal, and, based on the velocity information, generate, using the processor 135, and/or send, using the transceiver 165, a command to stay active in the search for the wanted vehicle to the one or more other autonomous vehicles that are less than a threshold distance from the autonomous vehicle that generated the positive identification signal.
The programming instructions, when executed, may be further configured to cause the processor 135 to generate, using the processor 135, and/or send, using the transceiver 165, a command to stay active in the search for the wanted vehicle to the autonomous vehicle that sent the positive identification signal until the wanted vehicle is no longer within a field of vision of the autonomous vehicle that sent the positive identification signal.
According to various embodiments, the wireless emergency alert system 300, the central autonomous vehicle dispatch 305, the one or more appropriate agencies and/or authorities 310, and/or the autonomous vehicles (e.g., AVs 105a, 105b, 105c, 105d, and/or 105e) are in electronic communication with each other via one or more wire and/or wireless connection such as, e.g., the cloud 315.

According to various embodiments, an emergency alert module of an autonomous vehicle may remain inactive until an active emergency alert has been received. The emergency alert may include a geographic region associated with the emergency alert and one or more identifiable markers of a wanted vehicle. According to various embodiments, the one or more identifiable markers may include one or more of one or more license plate characters of the wanted vehicle, a location associated with a license plate of the wanted vehicle, a make of the wanted vehicle, a model of the wanted vehicle, a color of the wanted vehicle, and/or other suitable identifiable markers.
At 402, it is determined whether an active emergency alert has been received. If no active emergency alert has been received, at 414, the emergency alert module remains inactive. If an active emergency alert has been received, then, at 404, the emergency alert module of the autonomous vehicle is activated and, at 406, a geographic region of the autonomous vehicle is determined. According to various embodiments, the geographic region of the autonomous vehicle is determined using one or more location detection systems coupled to the autonomous vehicle.
At 408, it is determined whether the geographic region of the autonomous vehicle is within the geographic region associated with the emergency alert. For example, if the geographic region of the autonomous vehicle is not within the geographic region associated with the emergency alert then, at 416, the plate reader module may remain inactive. In another example, if the geographic region of the autonomous vehicle is within the geographic region associated with the emergency alert then, at 410, a vehicle (a detected vehicle) may be detected and identified, within an environment of the autonomous vehicle, using one or more detection mechanisms of the autonomous vehicle. According to various embodiments, when the autonomous vehicle is within the geographic region associated with the emergency alert, for each identifiable marker, is it determined whether the detected vehicle matches the identifiable marker.
At 412, it is determined whether the make and/or model of the detected vehicle matches the make and/or model of the wanted vehicle in the emergency alert. For example, if the make and/or model of the detected vehicle does not match the make and/or model of the wanted vehicle in the emergency alert then, at 416, the plate reader module may remain inactive. If the make and/or model of the detected vehicle matches the make and/or model of the wanted vehicle in the emergency alert then, at 418, the plate reader module may be activated which detects and identifies the license plate on the detected vehicle and, at 420, a location associated with the license plate of the detected vehicle may be determined. The location associated with the license plate of the detected vehicle may be, e.g., a state or territory in which the detected vehicle is registered/licensed.
At 422, it is determined whether the location of the license plate of the detected vehicle matches the location associated with the wanted vehicle in the emergency alert. When the location associated with the license plate of the detected vehicle does not match the location associated with the license plate of the wanted vehicle in the emergency alert then, at 436, the analysis of the detected vehicle ends. When the location associated with the license plate of the detected vehicle matches the location associated with the license plate of the wanted vehicle in the emergency alert then, at 424, the license plate of the detected vehicle is analyzed and a character of the license plate of the detected vehicle is identified and determined.
At 426, it is determined whether the character of the license plate of the detected vehicle matches respective corresponding character of the wanted vehicle in the emergency alert. If the character of the license plate of the detected vehicle does not match the respective corresponding character of the license plate of the wanted vehicle in the emergency alert then, at 436, the analysis of the detected vehicle ends. If the character of the license plate of the detected vehicle matches the respective corresponding character of the license plate of the wanted vehicle in the emergency alert then, at 428, it is determined whether there are any subsequent characters remaining on the license plate of the detected vehicle. If there are subsequent characters remaining on the license plate of the detected vehicle then, for each subsequent character, steps 424, 426, and 428 are repeated. This process enables the license plate of the detected vehicle to be analyzed one character at a time, preventing the entire license plate of the detected vehicle to be analyzed if any one character of the license plate of the detected vehicle does not match the respective corresponding character of the license plate of the wanted vehicle in the emergency alert.
If there are no subsequent characters of the license plate of the detected vehicle then, at 430, it is determined whether the identifiable markers of the wanted vehicle have been met by the detected vehicle. According to various embodiments, if the identifiable markers have not been met by the detected vehicle then, at 436, the analysis of the detected vehicle ends. If the identifiable markers have been met by the detected vehicle then, at 432, the autonomous vehicle generates a positive identification signal, identifying the detected vehicle as the wanted vehicle of the emergency alert and, at 434, the positive identification signal is transmitted to one or more appropriate recipients. The positive identification signal may include information related to the location of the wanted vehicle, as well as information related to the speed of the wanted vehicle. Additionally, if one or more of the sensors have captured any information related to the occupants of the vehicle (e.g., whether a suspect and/or victim appear to be in the wanted vehicle, any identifying characteristics of the occupants, such as, e.g., clothing, and/or other suitable information related to the occupants of the vehicle), then such information may also be transmitted to the authorities as part of the positive identification signal.

For example, the on-board computing device 620 may be configured to control: braking via a brake controller 622; direction via a steering controller 624; speed and acceleration via a throttle controller 626 (in a gas-powered vehicle) or a motor speed controller 628 (such as a current level controller in an electric vehicle); a differential gear controller 630 (in vehicles with transmissions); and/or other controllers.
Geographic location information may be communicated from the location sensor 644 to the on-board computing device 620, which may then access a map of the environment that corresponds to the location information to determine known fixed features of the environment such as streets, buildings, stop signs and/or stop/go signals. Captured images from the cameras 646 and/or object detection information captured from sensors such as LiDAR 648 is communicated from those sensors to the on-board computing device 620. The object detection information and/or captured images are processed by the on-board computing device 620 to detect objects in proximity to the vehicle. Any known or to be known technique for making an object detection based on sensor data and/or captured images may be used in the embodiments disclosed in this document.
The features and functions described above, as well as alternatives, may be combined into many other different systems or applications. Various alternatives, modifications, variations or improvements may be made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
