A drive control system for driving an electrically driven window or sun roof is disclosed. A control unit drives a vehicle mounted device until it reaches a limit position when an ignition key is not inserted and when a door of the vehicle closes. Accordingly, a usual operation by a driver of the vehicle which occurs when he stops and gets out of the vehicle involves stopping the engine, withdrawing the ignition key, opening the door to get out of the vehicle, and closing the door. When it is desired to leave the window or sun roof in a half-open condition in order to prevent the parked car from overheating, the control unit stores any drive of a vehicle mounted device in response to an input when the ignition key is not inserted into the receptacle of the ignition switch, and controllably drives the vehicle mounted device until it reaches a limit position in response to a combination of the absence of the ignition key inserted into the receptacle, a closing of the door and the absence of stored information. Also an alarm unit is provided in combination with means which energizes the alarm unit whenever an induced current through a motor of a drive mechanism, when it is not energized, exceeds a given value. In this manner, an alarm is produced when a side window or sun roof is tampered open while the vehicle is parked.
