PURPOSE: To prevent the damage of an inverter by the counter-electromotive force during the regenerative drive of the motor of a motor car. CONSTITUTION: An electronic control unit 10 for controlling an inverter 6 provided between the main battery 3 and a motor 1 of a motor car has feedback control means 27 for bringing the real power calculated from a current IPDU and a voltage VPDU input to the inverter 6 into coincidence with the target power calculated from number of revolutions of motor Nm, an accelerator opening θAP and a shift position P. When the circuit between the battery 3 and the motor 1 is opened during the regenerative drive of the motor 1 to allow the charging of the battery 3 by the regenerative power to become impossible with the result that the voltage VPDU increases over a predetermined value, regeneration inhibiting means 26 inhibits the regenerative drive of the motor 1 to prevent the damage of the inverter 6 due to the counter-electromotive voltage of the motor 1. |
