Claim:
1. A control system for fail safety of a motor driven power steering (MDPS), the control system comprising: a straight motion/turning determination module for determining whether a vehicle is in a straight motion or turning based on a steering angle of a steering wheel, a steering torque of the steering wheel and a vehicle speed of the vehicle; a fail determination module for determining whether an MDPS fail occurs based on a steering torque of a driver and a motor torque of the MDPS, if the straight motion/turning determination module determines that the vehicle is in the straight motion; a fail type determination module for determining a type of the MDPS fail using a yaw rate change rate, if the fail determination module determines that the MDPS fail occurs; and a yaw rate change rate detection module for inputting the yaw rate change rate to the fail type determination module.
