摘要： A lane tracking system for tracking the position of a vehicle within a lane includes a camera configured to provide a video feed representative of a field of view and a video processor configured to receive the video feed from the camera and to generate latent video-based position data indicative of the position of the vehicle within the lane. The system further includes a vehicle motion sensor configured to generate vehicle motion data indicative of the motion of the vehicle, and a lane tracking processor. The lane tracking processor is configured to receive the video-based position data, updated at a first frequency; receive the sensed vehicle motion data, updated at a second frequency; estimate the position of the vehicle within the lane from the sensed vehicle motion data; and fuse the video-based position data with the estimate of the vehicle position within the lane using a Kalman filter.

摘要： A lane tracking system for a vehicle includes a front steering controller, a rear steering controller, and a lane tracking processor. The front steering controller is configured to rotate a front wheel of the vehicle through a front steering angle in response to a front steering torque command, and the rear steering controller is configured to rotate a rear wheel of the vehicle through a rear steering angle in response to a rear steering torque command. The lane tracking processor is configured to determine a desired course of the vehicle along a roadway, estimate a trajectory of the vehicle based on sensed vehicle motion, compute an error between the determined desired course and the estimated trajectory, and provide a front steering torque command to the front steering controller, and a rear steering torque command to the rear steering controller to minimize the computed error.

A region of feasible starting locations for successfully performing a parallel parking maneuver is determined by a processor. A position of the vehicle relative to the region of feasible starting locations is determined. A determination is made whether the vehicle is in a zero heading position. The vehicle is guided along an initial target path by controlling a steering actuator until the vehicle is in a zero heading position relative to the road of travel in response to the vehicle is not in the zero heading position. A planned path is generated that includes two arc-shaped trajectories extending between the vehicle at the zero heading position and a position within the region of feasible starting locations as determined by the processor.
