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 safe-to-proceed system (10) for operating an automated vehicle proximate to an intersection (14) includes an intersection-detector (18), a vehicle-detector (20), and a controller (24). The intersection-detector (18) is suitable for use on a host-vehicle (12). The intersection-detector (18) is used to determine when a host-vehicle (12) is proximate to an intersection (14). The vehicle-detector (20) is also suitable for use on the host- vehicle (12). The vehicle-detector (20) is used to estimate a stopping-distance (22) of an other- vehicle (16) approaching the intersection (14). The controller (24) is in communication with the intersection-detector (18) and the vehicle-detector (20). The controller (24) is configured to prevent the host-vehicle (12) from entering the intersection (14) when the stopping-distance (22) indicates that the other-vehicle (16) will enter the intersection (14) before stopping.

Abstract:
A brake control system (10) for operating brakes (18) of an automated vehicle at slow speed includes a motion-detector (22) and a controller (34). The motion-detector (22) detects relative-movement (24) of a host-vehicle (12) relative to a stationary-feature (26) located apart from the host-vehicle (12). The controller (34) is configured to operate brakes (18) of the host-vehicle (12). The controller (34) determines a vehicle-speed (36) of the host-vehicle (12) based on the relative-movement (24) when the vehicle-speed (36) is less than a speed-threshold (40), and regulates brake-pressure (36) of the brakes (18) based on the vehicle-speed (36).
Abstract:
A navigation system (10) for an automated vehicle includes a receiver (14), a three-dimensional-model (3D-model (26)), and a controller (40). The receiver (14) detects signals (16) from satellites (18) for determining a location (20) of a host-vehicle (12) on a digital-map (22). The 3D-model (26) depicts objects (28) in an area (30) proximate the host- vehicle (12). The controller (40) is in communication with the receiver (14) and the 3D-model (26). The controller (40) ignores a signal (38) of a satellite (34) detected by the receiver (14) when the satellite (34) is determined to be hidden (50A) by an object (28A) in the 3D-model (26).
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).
