Abstract
There is provided a failsafe device for a shift-by-wire system, including: a parking range operation unit with which a diver inputs a request to shift to a parking range; a control unit that changes the state of an automatic transmission to a parking range state in response to the shift request from the parking range operation unit; a failure determination unit that determines whether or not the actual state of the automatic transmission is the parking range state; and a brake device that brakes wheels of a vehicle with an actuator. The control unit brakes the wheels with the brake device when the failure determination unit determines that the actual state of the automatic transmission is not the parking range state after the request to shift to the parking range has been issued from the parking range operation unit.
