Zusammenfassung:	PROBLEM TO BE SOLVED: To perform highly accurate positional detection, while following up inertial rotation of a motor after tripping power supply for the motor by counting pulse signals generated continuously from a pulse generator for a time set with a timer after tripping the power supply. SOLUTION: A control unit ECU takes pulse signals Pa, Pb of respective phases generated from a pulser into an external interruption input for a time which is preset in an internal timer, after a battery power supply BAT is tripped from a motor M by turning a master switch M/SW off and continues pulse count until an external interrupt is prohibited upon waiting for the expiration of the set time. When the timer is set with a time, while taking account of the time being elapsed before the motor M is stopped perfectly after tripping the battery power supply BAT, open/close position of an window glass which charges by the rotation of the motor inertia after tripping the battery power supply BAT can be detected accurately. Furthermore, miscount due to external noise can be prevented.
