Abstract
The vehicle drive system includes a motor that has a stator and a rotor provided in the stator and that drives a drive wheel of a vehicle by rotation of the rotor. The rotor has: plural secondary conductors that are aligned in a circumferential direction in a radially outer portion; and plural permanent magnets that are aligned in the circumferential direction in a portion on a radially inner side of these plural secondary conductors. An ECU and a motor ECU capable of switching a drive mode of the motor between a synchronous operation mode and an asynchronous operation mode are further provided. Based on required output for the motor, the ECU and the motor ECU are configured to switch the drive mode of the motor from the synchronous operation mode to the asynchronous operation mode.
