Abstract:
A system (10) for automated operation of a host-vehicle (12) includes an object- sensor (16), a global-positioning-system-receiver (GPS-receiver (26)), and a controller (40). The object-sensor (16) is used to determine a first-polynomial (18) indicative of a preferred-steering-path (20) based on an object (22) detected proximate to a host-vehicle (12). The GPS-receiver (26) is used to determine a second-polynomial (30) indicative of an alternative- steering-path (28) based on a GPS-map (32). The controller (40) is configured to steer the host-vehicle (12) in accordance with the first-polynomial (18) when the object (22) is detected, and steer the host- vehicle (12) in accordance with the second-polynomial (30) when the object (22) is not detected. The improvement allows the system (10) to make use of a less expensive/less accurate version of the GPS-receiver (26), and a less complicated GPS-map (32) than would be anticipated as necessary for automated steering of the host-vehicle (12) using only the GPS-receiver (26) and the GPS-map (32).
Abstract:
A humanized steering system (10) for an automated vehicle (12) includes one or more steering-wheels (16) operable to steer a vehicle (12), an angle-sensor (20) configured to determine a steering-angle (18) of the steering-wheels (16), a hand-wheel (22) used by an operator (14) of the vehicle (12) to influence the steering-angle (18) and thereby manually steer the vehicle (12), a steering-actuator (24) operable to influence the steering-angle (18) thereby steer the vehicle (12) when the operator (14) does not manually steer the vehicle (12), a position-sensor (26) operable to indicate a relative-position (28) an object (30) proximate to the vehicle (12), and a controller (32). The controller (32) is configured to receive the steering-angle (18) and the relative-position (28), determine, using deep-learning techniques, a steering-model (34) based on the steering-angle (18) and the relative-position (28), and operate the steering-actuator (24) when the operator (14) does not manually steer the vehicle (12) to steer the vehicle (12) in accordance with the steering-model (34), whereby the vehicle (12) is steered in a manner similar to how the operator (14) manually steers the vehicle (12).
Abstract:
A system (10) for automated operation of a host-vehicle (12) includes a sensor (20), a data-source (24), and a controller (22). The sensor (20) is installed in a host- vehicle (12). The sensor (20) is operable to determine a state-of-awareness (18) of an operator (14) of the host-vehicle (12). The data-source (24) provides route-data (26) used for automated operation of the host-vehicle (12). The route-data (26) includes a map (28) and a control-rule (30) for navigating the map (28). The controller (22) is in communication with the sensor (20) and the data- source (24). The controller (22) is configured to operate the host-vehicle (12) during automated operation of the host- vehicle (12) in accordance with the route-data (26). The controller (22) is also configured to modify the control-rule (30) based on the state-of-awareness (18) of the operator (14).
Abstract:
A tire-wear detection system (10) for an automated vehicle includes a steering- angle-sensor (18), a vehicle-path-detector (24), and a controller (30). The steering-angle-sensor (18) indicates a steering-angle (20) of a host-vehicle (12). The vehicle-path-detector (24) indicates a turning-radius (26) of the host-vehicle (12). The controller (30) is in communication with the steering-angle-sensor (18) and the vehicle -path-detector (24). The controller (30) determines a wear-status (32) of a tire of the host-vehicle (12) based on the turning-radius (26) and the steering- angle (20).
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).
