Abstract
A drive system establishes a normal state in which a first switch is ON and a gang switch is OFF, in the case where it is determined that there is no abnormality in the state of a first rotating body driven by a first motor. In this normal state, the first motor is driven by a first inverter, while a second motor is driven by a second inverter. It the case where it is determined that there is abnormality in the state of the first rotating body, a first countermeasure state is established in which the first switch is OFF and the gang switch is ON. In this first countermeasure state, the second motor is driven by both the first inverter and the second inverter.
