ABSTRACT:
A first restrict value calculating unit obtains a first restrict value Im1on the basis of the integration value (Id2+Iq2) of a d-axis current detection value and a q-axis current detection value. A second restrict value calculator50calculates a second restrict value Im2on the basis of the maximum value of the integration values of the squares Iu2, Iv2, and Iw2of 3-phase current detection values. A target current value It calculated by a target current calculating unit21is restricted by so that a current value limiter so as to be not greater than the first restrict value Im1and the second restrict value Im2. By using the two restrict value restricting the motor driving current, it is possible to control properly the motor driving current in accordance with a general driving condition and various steering conditions.
