摘要： Current detecting circuits are provided for all phases of a motor driving circuit. A motor control portion is provided with a correction value calculating unit for calculating a correction value by dividing a total sum of motor current values based on detecting signals detected by the current detecting circuits of all the phases by a number of the phases of a motor and a motor current value correcting unit for correcting the motor current values by subtracting the correction value from the motor current values based on values of currents actually flowing in the respective phases of the motor. Thereby, the motor is driven.

摘要： The torque sensor outputs a sinusoidal first alternating signal the phase of which changes in accordance with change in the rotation angle of a first shaft, and a sinusoidal second alternating signal the phase of which changes in accordance with change in the rotation angle of a second shaft capable of performing relative rotation, elastically, with respect to the first shaft. A phase difference correspondence signal the waveform of which changes in accordance with change in the phase difference between the first alternating signal and the second alternating signal is output. A value corresponding to the torque transmitted by the first and second shafts is determined from the phase difference correspondence signal. This value corresponding to the transmitted torque is corrected on the basis of a value corresponding to the difference between a first distortion indicator value which changes in accordance with the waveform distortion in the first alternating signal and a second distortion indicator value which changes in accordance with the waveform distortion in the second alternating signal.

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.
