Abstract:
A sunroof controlling device for controlling a sunroof of a motor vehicle comprising:an actuator provided with an electric motor having an armature shaft, a reduction gear driven by rotation of the armature shaft of said electric motor and an output shaft combined with said reduction gear;a switch for generating a command signal to drive the electric motor of said actuator; anda control unit electrically connected to said switch and said electric motor of the actuator, and including an armature shaft rotation signal generating means for generating an armature shaft rotation signal according to rotation of said armature shaft of the electric motor, an output shaft rotation signal generating means for generating an output shaft rotation signal according to rotation of said output shaft of the actuator, and a counting means for counting the armature shaft rotation signal generated from said armature shaft rotation signal generating means and the output shaft rotation signal generated from said output shaft rotation signal generating means;wherein said control unit starts current supply to said electric motor of the actuator in response to the command signal supplied from said switch, and interrupts the current supply to the electric motor of said actuator when the count value of said counting means amounts to predetermined value,wherein said counting means starts counting pulses of the armature shaft rotation signal generated from said armature shaft rotation signal generating means when a pulse edge of the output shaft rotation signal generated from said output shaft rotation signal generating means is detected.
