摘要： A first restrict value calculating unit obtains a first restrict value Im1 on 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 calculator 50 calculates a second restrict value Im2 on the basis of the maximum value of the integration values of the squares Iu2, Iv2, and Iw2 of 3-phase current detection values. A target current value It calculated by a target current calculating unit 21 is restricted by so that a current value limiter so as to be not greater than the first restrict value Im1 and 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.

摘要： When a source consisting of series-connected battery 7 and auxiliary power supply 9 supplies an electric power to a motor 4, a MOS-FET 13 for preventing a current induced by a voltage of the auxiliary power supply 9 from being reversed upstream should be off if it operates normally. Therefore, voltages at the opposite terminals of the MOS-FET 13 should have a difference which corresponds to a voltage of the auxiliary power supply 9. Hence, the voltages at the opposite terminals of the MOS-FET 13 are detected by two voltage detectors 23 and 25 when the electric power from the auxiliary power supply 9 is supplied to the motor 4. If the potential difference between the voltages at the opposite terminals of the MOS-FET 13 is equal to or less than a predetermined value, a control circuit 24 issues a failure signal upon determination that the MOS-FET 13 suffers a short-circuit fault. A MOS-FET 15 is also monitored in the same way.
