Summary:PROBLEM TO BE SOLVED: To exhibit energy-saving effect during high-speed running, and to comfortably steer a steering wheel during low-speed running. SOLUTION: A steering angle θ and a solenoid current command value I1 are determined on the basis of a theoretical value such that the relationship between the steering angle θ and a control flow QP have linear characteristic. The relationship between a steering angle speed ω and a solenoid current command value I2 is determined on a basis of a theoretical value such that the steering angle speed ω and the control flow QP have linear characteristic. However, there is provided a dead zone where both of the command values I1 and I2 output zero, unless the steering angle θ and the steering angle speed ωare above a preset value. In the dead zone, the preset value is changed according to the car speed (v).
