Abstract

A vehicle includes an electric motor to move the vehicle. A motor driver is configured to convert direct-current power supplied from a voltage converter to an alternating-current power and to convert the alternating-current power supplied from the electric motor to direct-current power. Circuitry is configured to drive the electric motor with a first current value to generate a drive force to consume excess electric power. The first current value is different from a minimum current value to generate the same drive force. The circuitry is configured to drive the electric motor with a second current value smaller than the first current value to decrease the electric power consumption of the electric motor when a temperature of the electric motor exceeds a first threshold temperature or a temperature of the motor driver exceeds a second threshold temperature.
