Title: AUTOMATED VEHICLE STEERING CONTROL SYSTEM WITH LANE POSITION BIAS
Abstract: [0001]    A steering-control system (10) for an automated vehicle includes an object-detector (20) and a controller (22). The object-detector (20) is suitable for use on a host-vehicle (12). The object-detector (20) is used to detect an other-vehicle (18) approaching the host-vehicle (12), and to detect a stationary-object (42) that defines a roadway (40) traveled by the host-vehicle (12). The controller (22) is in communication with the object-detector (20) and adapted to operate the host-vehicle (12). The controller (22) is configured to steer the host-vehicle (12) towards a centered-position (60) of a travel-lane (38) of the roadway (40) when a projected-path (62) of the other-vehicle (18) approaches the host-vehicle (12) to a minimum-distance (64) between the other-vehicle (18) and the host-vehicle (12) greater than a distance-threshold (66). The controller (22) is also configured to steer the host-vehicle (12) towards a biased-position (68) of the travel-lane (38) to increase the minimum-distance (64) when the projected-path (62) approaches the host-vehicle (12) to less than the distance-threshold (66) if the host-vehicle (12) remains in the centered-position (60).

Claims: number: 1
text: A steering-control system (10) for an automated vehicle, said system (10) comprising:
number: 2
text: The system (10) in accordance with claim 1, wherein the stationary-object (42) is one of, a lane-marking (44), a road-sign (46), a guardrail (48), a shoulder (52), and a road-edge (54).
number: 3
text: The system (10) in accordance with claim 1 or 2, wherein the controller (22) is further configured to change a speed (74) of the host-vehicle (12) when the projected-path (62) approaches the host-vehicle (12) to less than the distance-threshold (66) if the host-vehicle (12) remains in the biased-position (68).
number: 4
text: The system (10) in accordance with any one of claims 1 to 3, wherein the controller (22) is further configured to steer the host-vehicle (12) to change the travel-lane (38) of the host-vehicle (12) when the projected-path (62) approaches the host-vehicle (12) to less than the distance-threshold (66) if the host-vehicle (12) remains in the biased-position (68).
