Electric vehicle drive control apparatus and method and program thereof
DRIVE
February 12, 2003
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; battery voltage detection means for detecting the battery voltage; and electric machine torque restriction processing means for determining whether the battery voltage is higher than a threshold value, and for restricting 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.
