1. A lane centering system for use in a vehicle driving in a lane on a road, the lane centering system comprising:

  • a camera disposed behind a windshield of a vehicle and having a field of view through the windshield and forward of the vehicle that encompasses the road ahead of the vehicle and being travelled on by the vehicle;

    wherein the camera captures image data;

    a controller;

    wherein the controller comprises a processor that processes image data captured by the camera to detect lane delimiters on the road ahead of the vehicle;

    wherein, based on processing by the processor of image data captured by the camera, the controller determines the position of a left lane delimiter on the road on a left side of the vehicle and the position of a right lane delimiter on the road on a right side of the vehicle;

    wherein the controller is operable to control a steering system of the vehicle that is configured to steer the vehicle;

    wherein the controller is operable to determine a target path for the vehicle based on processing by the processor of image data captured by the camera;

    wherein the determined target path maintains the longitudinal centerline of the vehicle centered between the left lane delimiter and the right lane delimiter;

    wherein the lane centering system is enabled responsive to at least one of (i) a user input and (ii) speed of the vehicle exceeding a threshold level; and

    wherein the lane centering system is disabled when a collision avoidance system of the vehicle that determines a collision may occur has been triggered in order to permit maneuvering of the vehicle to avoid a collision without interference from the lane centering system.
