Vehicle lane departure warning system and method

摘要

A vehicle lane departure warning system and method are provided. The system includes a position sensor for sensing position of a vehicle and memory storing learned vehicle path data. The system further includes a controller for processing the position data and determining a stored learned vehicle path that the vehicle is travelling on. The controller comprises logic for comparing the sensed position data to the stored learned vehicle path and determining if the vehicle is sufficiently departing from the stored learn vehicle path. The system further includes an output for providing a warning signal indicative of the vehicle departing from the stored learned vehicle path. The stored learned vehicle path is updated as the vehicle repeatedly travels on the path.
