Abstract: A cross traffic detection system suitable for use on an automated vehicle includes an object-detector, an alert-device, and a controller. The object detector is used to determine locations of moving objects relative to a host vehicle. The alert device is used to alert an operator of the host vehicle to the location of the moving objects. The controller is in communication with the object detector and the alert device. The controller determines a first trail of a first moving object based on the locations of the first moving object, and determines a road model based on a polynomial of the first trail. The controller also determines a second trail of a second moving object, assigns a lane number to the second moving object based on the road model, and activates the alert device when the path of the second moving object resides in the lane-number overlain by a conflict zone.

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-control system suitable for use on an automated vehicle comprising a camera, a lidar-sensor, and a controller. The camera captures an image of a roadway traveled by a host-vehicle. The lidar-sensor detects a discontinuity in the roadway. The controller is in communication with the camera and the lidar-sensor and defines an area-of-interest within the image, constructs a road-model of the roadway based on the area-of-interest, determines that the host-vehicle is approaching the discontinuity, and adjusts the area-of-interest within the image based on the discontinuity.

Abstract: An environmental sensing system relating to vehicle lane position includes first and second sensors respectively configured to provide first and second signals indicative of a vehicle lane position. A steering system achieves a desired lane position in response to a command from a controller to keep the vehicle in its lane, for example, during autonomous control of the vehicle. The controller uses the first signal if the first sensor provides a desired lane marker confidence. The controller switches to the second sensor and uses the second signal if the first sensor cannot provide the desired lane marker confidence and the second sensor can provide the desired lane marker confidence.

Abstract: A driver-fatigue warning system suitable for use in an automated vehicle includes a camera, an alert-device, and a controller. The camera renders an image of a lane-marking and of an object proximate to a host-vehicle. The alert-device is operable to alert an operator of the host-vehicle of driver-fatigue. The controller is in communication with the camera and the alert-device. The controller determines a vehicle-offset of the host-vehicle relative to the lane-marking based on the image. The controller determines an offset-position of the object relative to the lane-marking based on the image. The controller determines that a lane-departure has occurred when the vehicle-offset is less than a deviation-threshold. The controller does not count occurrences of lane-departures when the offset-position is less than an offset-threshold, and activates the alert-device when the count of the occurrences of lane-departures exceeds a crossing-threshold indicative of driver-fatigue.
