ABSTRACT:
An electric vehicle drive control apparatus has an electric machine; a battery; an inverter that is driven in accordance with a drive signal, and that receives DC current from the battery and produces phase currents, and that supplies the phase currents to the electric machine; a battery voltage detection device that detects the battery voltage; and an electric machine torque restriction processing device that determines whether the battery voltage is higher than a threshold value, and restricts the electric machine torque if the battery voltage is higher than the threshold value. If the battery voltage becomes higher than the threshold value, the electric machine torque is restricted. Therefore, increases in the load on the inverter can be prevented.
