First a driver model is established, wherein the driver model is established according to a lateral position error of a vehicle being driven and a steering angle generated by a driver for controlling the vehicle. Next, a system identification process is performed on the lateral position error and the steering angle, so as to obtain specific information of the driver model. An estimation process is performed on the specific information and a plurality of raw statistical data, so as to obtain a time to lane crossing (TLC). A decision process is performed on the TLC and a driver drowsiness index, so as to obtain a lane departure warning strategy.
