An autonomous vehicle is a vehicle that travels to a given destination by recognizing the surrounding environment without the driver's intervention, judging the driving situation, and controlling the vehicle. In an autonomous driving vehicle, the MDPS system is a system that performs a steering function by receiving an operating command of an autonomous driving system that the vehicle judges and drives completely independently of the driver. The risk of accidents is very high in case of failure of the steering device in the autonomous driving stage 3 or more without obligation of the driver. Therefore, a Full Redundancy MDPS system that requires normal steering function even when MDPS system fails is needed. The control system of the Full Redundancy MDPS can produce a normal 100% output with a double designed motor each output 50%. If one of the dual designed control systems fails, it can generate 50% of the output, so the MDPS system can maintain the steering force even in case of failure. In this paper, the method for producing 100% power even if one of the torque sensors fails among the dual-design control systems was described and the system was applied through the actual vehicle to proceed.
