A controller for controlling vehicle stability, the controller having first and second drive modes and including a processor for switching between the drive modes, the processor being configured to: receive 610 steering angle, vehicle speed, yaw rate, vehicle direction, and brake input signals; determine 615, 620, 625 whether the steering angle, vehicle speed, and yaw rate signals exceed a predetermined threshold; determine 630 whether the direction of travel of the vehicle is backward, based on the vehicle direction signal or reverse gear being engaged; and switch the controller from the first drive mode to the second drive mode if the vehicle speed, steering angle, and yaw rate signals exceed their respective predetermined thresholds and the direction of travel of the vehicle is backward; and apply 640 a braking force at a front axle of the vehicle so as to substantially lock front wheels of the vehicle. This can provide the advantage that the vehicle may perform a j-turn. Also provided is a method of controlling vehicle stability.
