When a driver turns on an accelerator, a CPU permits revolution of planetary gears, and a motor rotates a ring gear to drive wheels. Then, when the driver turns off the accelerator, the CPU calculates a target RPM to be output by a Stirling engine according to a depression amount and a depression time of the accelerator. When the RPM output by the Stirling engine reaches close to the target RPM, the revolution of the planetary gears is inhibited, the operation of the motor is stopped, and the Stirling engine rotates the ring gear via a sun gear and the planetary gears to drive the wheels.
