Abstract
An electric vehicle includes drive systems, a control apparatus that controls the drive systems, and wheels. Each drive system includes a motor and an inverter coupled by wires. The wires of the drive systems are coupled by first bypass lines. Each inverter converts direct current power supplied from a corresponding power supply into alternating current power and supplies the alternating current power to the corresponding motor. Each motor drives the corresponding wheel. When an abnormality occurs in the supply of the alternating current power from the inverter to the motor in one drive system, the control apparatus performs control (i) to stop the supply of the alternating current power from the inverter of the one drive systems, and (ii) to supply the alternating current power supplied from the inverter to the motor in another drive system, to the motor of the one drive system via the first bypass lines.
