PURPOSE:To enable to maintain preferably riding feeling even when the output voltage of a battery decreases by reducing the current command value in case that the current deviation increases the prescribed value or higher when the voltage of the battery decreases. CONSTITUTION:A CPU4 outputs a current command value i* in response to the voltage from a pedal potentiometer 2. A current controller 6 controls an inverter 8 in response to the current deviation between the current command value i* and the current detected value i. On the other hand, a Schmitt trigger 12 drives a one shot multivibrator 13 when the deviation becomes the set value or higher to set a flip-flop 14. The CPU4 subtracts the current command value by the prescribed value when the flip-flop 14 is set. Thus, the distortion of the input waveform for a motor can be eliminated, and preferably riding feeling can be maintained. |
