Abstract: A lane-keeping-assist system suitable for use on an automated vehicle includes a camera, a steering-actuator, and a controller. The camera detects a lane-marking of a travel-lane traveled by a host-vehicle. The steering-actuator controls a travel-direction of the host-vehicle. The controller is in communication with the camera and the steering-actuator. The controller determines a lane-width of the travel-lane and determines a centerline of the travel-lane based on the lane-marking. The controller further determines an offset-position of the host-vehicle within the travel-lane based on the lane-marking. The controller further determines a clearance between the host-vehicle and the lane-marking based on the offset-position. The controller further determines an adaptive-threshold based on the lane-width. The controller further determines that the host-vehicle is approaching the lane-marking when the clearance is less than the adaptive-threshold, and activates the steering-actuator to steer the host-vehicle toward the centerline of the travel-lane.

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.
