Abstract
An electric motor such as a driving source of an electric vehicle is controlled by the microcomputer. The microcomputercalculates a target torque Req_trq according to a throttle opening degree α, and outputting induction values (a current instruction value I and a angle instruction value θ) obtained referring to a map MP based on the target torque Req_trq (a motor rotational number Nm and a battery voltage Vb), the microcomputerperforms a torque control of an SR motor. The motor rotational number Nm detected from the SR motoris passed through a band pass filter. Passing by the band pass filter, a signal data of the extracted 0.1-50 Hz is executed a PD calculation process, the calculated corrected amount PD_out is subtracted from the target torque Req_trq.
