1. An electric vehicle drive control apparatus, comprising:

  • a drive source;

    a battery;

    an inverter that is driven in accordance with a drive signal, and that receives a direct current from the battery, and produces a phase current, and supplies the phase current to the drive source;

    a battery voltage detection device that detects a battery voltage; and

    a drive source torque restriction processing device that determines whether the battery voltage is higher than a threshold value, and restricts a drive source torque if the battery voltage is higher than the threshold value to prevent applying an increase in a voltage to the inverter.
