PROBLEM TO BE SOLVED: To provide a comfortable riding feeling for an automobile. SOLUTION: A main ECU 10 outputs a steering angle indication value, for example, with a 50 msec interval. An interpolation circuit 21 of a steering ECU 20 interpolates the indication value from the main ECU 10 to compute a target steering angle value, for example, in every 2.5 msec interval. A steering angle of a steering mechanism 30 is automatically controlled by a PID control part 23, a PWM control part 25 and the like based on the target steering angle value. Steering angle change is smoothened thereby to eliminate jolting behavior of a vehicle. |
