Abstract:
An object-detection system (10) suitable for use in an automated vehicle includes a transceiver (20), and object-detector (28), and a controller (36). The transceiver (20) is suitable to install on a host-vehicle (12). The transceiver (20) is used to receive an indicated-location (22) of an object (26) proximate to the host- vehicle (12). The object-detector (28) is suitable to install on the host-vehicle (12). The object-detector (28) is used to detect a relative-location (30) of the object (26) relative to the host-vehicle (12). The controller (36) is in communication with the transceiver (20) and the object-detector (28). The controller (36) determines a confirmed-location (40) of the object (26) relative to the host-vehicle (12) based on the indicated-location (22) and the relative-location (30). Determining the confirmed-location (40) of the object (26) allows for selecting from a variety of optimized algorithms to better track subsequent expected motion of the object (26), and reducing the risk of unnecessary or erratic action by the host-vehicle (12) caused by hacking of the wireless-transmission (24) or deliberate malicious content in the wireless-transmission (24).
Abstract:
An infrastructure-device status-verification system (10) suitable for use by an automated vehicle includes a transceiver (20), an object-detector (28), and a controller (32). The transceiver (20) is suitable to install on a host-vehicle (12). The transceiver (20) is used to receive an indicated-status (22) of an infrastructure-device (26). The object-detector (28) is suitable to install on the host-vehicle (12). The object-detector (28) is used to determine a detected- status (30) of the infrastructure-device (26). The controller (32) is in communication with the transceiver (20) and the object-detector (28). The controller (32) determines a confirmed-status (34) of the infrastructure-device (26) based on the indicated-status (22) and the detected-status (30). The system (10) provides for increased confidence and security regarding information about the status of an infrastructure-device (26) such as the traffic- signal (42) (e.g. red, yellow, and green), thereby avoid miss-information caused by, for example, hacking or spoofing of V2I communications from the infrastructure-device (26), and overcome instances when the field-of-view (36) between the object-detector (28) and the infrastructure-device 26 becomes occluded after the confirmed- status (34) has been established or determined.
Abstract:
A route-planning system (10) suitable for use on an automated vehicle (12) includes a memory (20) and a controller (30). The memory (20) is used to store map-data (22) indicative of a plurality of possible-routes (24) to a destination (26). Each possible- route is characterized by a difficulty-score (28). The controller (30) is in communication with the memory (20). The controller (30) is operable to select from the memory (20) a preferred-route (52) from the plurality of possible-routes (24). The preferred-route (52) is selected based on the difficulty-score (28).
Abstract:
An operation-security system (10) for an automated vehicle includes an object- detector (20) and a controller (40). The object-detector (20) includes at least three sensors. Each sensor is one of a camera (22) used to determine an image-location (32) of an object (18) proximate to a host-vehicle (12), a lidar-unit (24) used to determine a lidar- location (34) of the object (18) proximate to the host-vehicle (12), and a radar-unit (26) used to determine a radar-location (36) of the object (18) proximate to the host-vehicle (12). The controller (40) is in communication with the at least three sensors. The controller (40) is configured to determine a composite-location (46) based on a comparison of locations (32) indicated by the at least three sensors. Information from one sensor is ignored when a respective location indicated by the one sensor differs from the composite-location (46) by greater than an error-threshold (48). If a remote sensor (78) not on the host-vehicle (12) is used, V2V or V2I communications may be used to communicate a location to the host-vehicle (12).
Abstract:
A lane management system (10) for operating an automated vehicle includes a navigation-device (20), a vehicle-detector (34), and a controller (40) suitable for use on a host-vehicle (12). The navigation-device (20) is used to determine a preferred-route (22) to a destination (16) of the host-vehicle (12). The vehicle-detector (34) is used to determine a relative-location (36) of an other-vehicle (38) proximate to the host-vehicle (12). The controller (40) is in communication with the navigation-device (20) and the vehicle-detector (34). The controller (40) is configured to determine an alternate-route (44) when the relative-location (36) is such that a preferred-lane (46) of the preferred-route (22) is obstructed whereby the host-vehicle (12) is unable to follow the preferred- route (22). Alternatively, the controller (40) is configured to determine an initiate-time (48) to perform a lane-change (52) necessary to maneuver the host-vehicle (12) into a preferred-lane (46) of the preferred-route (22) so the host-vehicle (12) can follow the preferred-route (22), wherein the initiate-time (48) is determined based on the relative-location (36).
Abstract:
An intent-indication system (10) includes an intersection-detector (14), a vehicle-detector (20), and a controller (24). The intersection-detector (14) is suitable for use on a host-vehicle (12). The intersection-detector (14) is used to determine that the host-vehicle (12) is stopped at an intersection (16). The vehicle-detector (20) is also suitable for use on the host-vehicle (12). The vehicle-detector (20) is used to detect a presence of an other-vehicle (22) proximate to the intersection (16). The controller (24) is in communication with the intersection-detector (14) and the vehicle-detector (20). The controller (24) is configured to operate host-headlights (26) of the host-vehicle (12) to provide an indication of intent of the host-vehicle (12) to the other-vehicle (22) when the host-vehicle (12) and the other-vehicle (22) have been stopped at the intersection (16) for more than a time-threshold (28).
