Abstract:
A learning system (10) for an automated vehicle to learn local traffic customs includes a location-detector (16), and object-detector (20), and a controller (24). The location-detector (16) indicates a location (34) of a host-vehicle (12) on a digital-map (18). The object-detector (20) detects a lane-marking (14) and other-vehicles (22) proximate to the host-vehicle (12). The controller (24) is in communication with the location-detector (16) and the object-detector (20). The controller (24) is configured to determine when an observed-behavior (32) of the other-vehicles (22) is not in accordance with the lane-marking (14) present at the location (34), and operate the host-vehicle (12) in accordance with the observed-behavior (32).
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).
Abstract:
A roadway (18)-infrastructure-maintenance system (10) using automated-vehicles to maintain a roadway (18) includes an image-device and a controller (32). The imaging-device (14) is suitable to mount on a host-vehicle (12). The imaging-device (14) is used to detect an infrastructure-feature (16) proximate to a roadway (18) traveled by the host-vehicle (12). The controller (32) is in communication with the imaging-device (14). The controller (32) is configured to determine a need-for-maintenance (30) of the infrastructure-feature (16). The system (10) may include a digital-map (34) that indicates an expected-presence (36) of the infrastructure-feature (16), and the need-for-maintenance (30) may be indicated when the infrastructure-feature (16) is not-detected (66) as expected. The system (10) may also include a transmitter (42) in communication with the controller (32). The transmitter (42) may be used to communicate the need-for-maintenance (30) to a maintenance-organization (44).
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:
A driving-rule system (10) suitable to operate an automated includes a vehicle- detector (16) and a controller (20). The vehicle-detector (16) is suitable for use on a host- vehicle (12). The vehicle-detector (16) is used to detect movement of an other-vehicle (14) proximate to the host-vehicle (12). The controller (20) is in communication with the vehicle-detector (16). The controller (20) is configured to operate the host-vehicle (12) in accordance with a driving-rule (22), detect an observed-deviation (24) of the driving-rule (22) by the other-vehicle (14), and modify the driving-rule (22) based on the observed- deviation (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.
