VEHICLE CONTROL SYSTEM AND CONTROLLING METHOD THEREOF

Disclosed herein are a vehicle control system and controlling method thereof. The vehicle control system includes a plurality of sensors configured to measure a wheel speed, a steering angle, a yaw rate, and acceleration value, and a controller estimating the state of a vehicle based on the wheel speed, the steering angle, the yaw rate, and the acceleration value and updating a front and rear wheel stiffness of the vehicle when it is determined that the vehicle is running on an asymmetric friction surface from the estimated state of the vehicle.
