PROBLEM TO BE SOLVED: To improve a feeling in a steering wheel operation at determining a turning angle so as to be similar to a feeling in a constitution in which a steering wheel and a dirigible road wheel are mechanically coupled to each other. SOLUTION: A difference angle ΔH between the steering wheel and the dirigible road wheel is calculated (S140), and a motor output command value Dm depending on the difference angle ΔH is calculated (S150, and S180 to S200). At the moment of turning the steering wheel operation or of stopping of steering (S100), steering wheel positioning information is made to correspond to positioning information of the dirigible road wheel (S110). Accordingly, the difference angle ΔH is reset to be zero, and the output command value Dm is set to '0' thereby stopping driving of a power steering motor. |
