Abstract: A lane-keeping system suitable for use on an automated vehicle includes a camera, an inertial-measurement-unit, and a controller. The camera is configured to detect a lane-marking of a roadway traveled by a vehicle. The inertial-measurement-unit is configured to determine relative-motion of the vehicle. The controller in communication with the camera and the inertial-measurement-unit. When the lane-marking is detected the controller is configured to steer the vehicle towards a centerline of the roadway based on a last-position, and determine an offset-vector indicative of motion of the vehicle relative to the centerline of the roadway. When the lane-marking is not detected the controller is configured to: determine an offset-position relative to the last-position based on information from the inertial-measurement-unit, determine a correction-vector used to steer the vehicle from the offset-position towards the centerline of the roadway based on the last-position and the offset-vector, and steer the vehicle according to the correction-vector.

Abstract: A steering-control system for an automated vehicle includes an object-detector and a controller. The object-detector is suitable for use on a host-vehicle. The object-detector is used to detect an other-vehicle approaching the host-vehicle, and to detect a stationary-object that defines a roadway traveled by the host-vehicle. The controller is in communication with the object-detector and adapted to operate the host-vehicle. The controller is configured to steer the host-vehicle towards a centered-position of a travel-lane of the roadway when a projected-path of the other-vehicle approaches the host-vehicle to a minimum-distance between the other-vehicle and the host-vehicle greater than a distance-threshold. The controller is also configured to steer the host-vehicle towards a biased-position of the travel-lane to increase the minimum-distance when the projected-path approaches the host-vehicle to less than the distance-threshold if the host-vehicle remains in the centered-position.

Abstract: A lane-changing system suitable for use on an automated host-vehicle includes a camera, an inertial-measurement-unit, and a controller. The camera detects a lane-marking of a roadway traveled by a host-host-vehicle. The inertial-measurement-unit determines relative-motion of the host-host-vehicle. The controller is in communication with the camera and the inertial-measurement-unit. While the lane-marking is detected the controller steers the host-host-vehicle towards a centerline of an adjacent-lane of the roadway based on a last-position and a current-vector, and determines an offset-vector indicative of motion of the host-host-vehicle relative to the current-vector. While the lane-marking is not detected the controller determines an offset-position relative to the last-position based on information from the inertial-measurement-unit, determines a correction-vector used to steer the host-host-vehicle from the offset-position towards the centerline of the adjacent-lane of the roadway based on the last-position and the offset-vector, and steers the host-host-vehicle according to the correction-vector towards the centerline of the adjacent-lane.

Abstract: A lane-change system suitable for use on an automated-vehicle includes a camera, a ranging-device, and a controller. The camera is used to detect an image of a lane-marking on a roadway traveled by a host-vehicle. The ranging-device is used to determine a distance and a direction from the host-vehicle to an other-vehicle proximate to the host-vehicle. The controller is in communication with the camera and the ranging-device. The controller is configured to control a lane-change by the host-vehicle in accordance with the image when the lane-marking is detected, and control the lane-change in accordance with the distance and the direction to the other-vehicle when the lane-marking is not detected.

Abstract: A lane keeping system for a vehicle includes a first roll angle sensor configured to provide a first signal indicative of dynamic vehicle body roll. A second roll angle sensor is configured to provide a second signal indicative of an angle between vehicle sprung and unsprung masses. A lane keeping system (LKS) controller is in communication with the first and second roll angle sensors. The LKS controller is configured to discern a vehicle roll angle in response to the first and second signals based upon effects of a lateral wind force on the vehicle. The LKS controller is configured to produce a correction in response to the determined lateral wind force effects to maintain the vehicle along a desired path.

Abstract: A lane keeping system includes an absolute pressure sensor located in a door on each of opposing sides of a vehicle. Each sensor generates a signal indicative of a door cavity pressure on that side of the vehicle. A safety restraint system (SRS) controller is in communication with the pressure sensor. The SRS controller is configured to determine a collision event in response to the signal (e.g., increased pressure in the door as it is crushed) and activate a safety restraint component in response to the determined collision event. A lane keeping system (LKS) controller is in communication with the pressure sensors. The LKS controller determines a lateral wind force on the vehicle in response to the signal from each pressure sensor. The LKS controller determines a correction in response to the determined lateral wind force to maintain the vehicle along a desired path.
