The rear wheel steering controller provides steering angle information of the rear wheel for a current steering controller, and the front wheel steering controller. The front wheel controller determines a steering compensation value to compensate Yaw generation if the rear wheel steering angle provided by the rear steering controller is equal to the front wheel steering angle, and then adjusts a front steering angle by adding the steering compensation value to a front gear ratio.

Abstract: Disclosed is a fail safe control method for a variable rack stroke system which normally provides a variable rack stroke control by estimating a steering angle based on encoder signals of an MDPS motor when a steering angle sensor is malfunctioned during the variable rack stroke control using an MDPS. The method includes a step of determining whether or not a malfunction of the steering angle sensor is detected during a drive state in which the variable rack stroke is controlled; a step of determining whether or not a vehicle is straightly driven by applying a yaw rate which is a rotation-angular speed of the vehicle and a vehicle speed when the malfunction of the steering angle sensor is detected; a step of determining a spot where the straight drive of the vehicle is determined as a neutral angle of a handle and setting the spot as a zero point of an encoder; and a step of controlling the variable rack stroke by estimating the steering angle by counting the encoder signals which is set as the zero point and calculating the displacement of the rack stroke according to the estimated steering angle.
