Method and apparatus for vehicle path tracking with error correction
A method for vehicle path tracking with error correction comprises steps of: acquiring vehicle instant information and a target path; developing a predictive path in accordance with the vehicle instant information; determining a vehicle yaw rate threshold value in accordance with the vehicle instant information; calculating a steering angle corresponding to the vehicle yaw rate threshold value; estimating a lateral error correction value corresponding to the steering angle; determining whether the lateral error correction value is not greater than an error value between the target path and the predictive path; controlling a vehicle to turn the steering angle corresponding to the lateral error correction value when the lateral error correction value is less than the error value; and controlling the vehicle to turn the steering angle corresponding to the error value when the lateral error correction value is greater than the error value.
