The intent to exit a vehicle when a driver attempts to exit a vehicle is detected by an exit intent detection unit, and regardless of whether or not the shift range other than the parking range is detected by a shift range detection unit, a securing control unit controls a vehicle securing unit and secures the vehicle when an intent to secure is detected by a securing intent detection unit. Thus, unintended vehicle movement after exiting is suppressed by securing the vehicle in a stopped state during exiting.
