Abstract
A control device supplies electric power to a shift-by-wire system to a sub power supply until starting of an engine by automatic start control is completed after the engine has been stopped by automatic stop control. The control device performs a stopped range switching process in response to outputting of a signal for requiring switching of a shift range from a selection device when electric power is supplied from the sub power supply to the shift-by-wire system. In the stopped range switching process, the shift range is switched to a selected shift range when a voltage of the sub power supply is equal to or greater than a threshold value. On the other hand, the shift range is switched to a neutral range when the voltage of the sub power supply is less than the threshold value.
