A torque sensor fault detection method is provided. When a torque sensor is normal when a vehicle is going straight, the torque sensor points to a torque midpoint, but when the vehicle is going straight on an inclined road, the torque midpoint is offset due to the slope of the road surface, and the torque sensor is mistakenly detected to be faulty. If a direction of a rudder angle is opposite to an offset direction of a detection value of the torque sensor, it may be judged that the torque sensor is faulty. If the two are in the same direction, the vehicle is travelling on the inclined road, and it may be judged that the torque sensor is normal, without being mistakenly detected to be faulty.
