Abstract
A front-vehicle path-following system and a method thereof are applied to a host vehicle. The host vehicle receives front-vehicle information and detects the host-vehicle information of a front vehicle. The system generates two paths, one is a front-vehicle estimation path generated based on the host-vehicle information, and the other is a front-vehicle wheel speed path generated based on the front-vehicle information. The location of the host vehicle currently located on the front-vehicle wheel speed path is matched as a path following start point. A following path decision is made based on the states of the two paths. Finally, control the host vehicle to follow one of the two paths based on the tracking path decision. The present invention can follow the path of the front vehicle to achieve steering and following purposes when failing to detect lane lines.
