Abstract

PURPOSE:To perfectly prevent the influence of the rotor inertia in an electric motor by adding the accelerating speed obtained on the basis of the steering angle detected by an angle sensor onto a steering torque output signal. CONSTITUTION:An angle sensor 22 is connected with an angle signal processing circuit 38 and an angle sensor anomaly detecting circuit 39, and said anomaly detecting circuit 39 is connected with an OR gate 35. The angle signal processing circuit 38 is connected with the first differential circuit 40, and the first differential circuit 40 is connected with the second differential circuit 41, and said second differential circuit 41 is connected with an addition circuit 37. Further, the angle signal processing circuit 38 is connected with a reversal circuit 42 in parallel with the first differential circuit 40, and the reversal circuit 42 is connected with the addition circuit 37 through a limitter circuit 43. A signal for controlling a motor driving circuit 44 is outputted from the addition circuit 37, and an electric motor (m) is controlled by said signal.
