Abstract:
A sunroof controlling device for controlling a sunroof of a motor vehicle comprising:a first switch for generating a slide open-tilt down signal;a second switch for generating a slide close-tilt up signal;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 for driving a sunroof lid of the motor vehicle in a slide-opening direction, a slide-closing direction, a tilt-downward direction or a tilt-upward direction; anda control unit electrically connected to said first and second switches and said electric motor of the actuator, and including a first rotation signal generating means for generating a first rotation signal according to rotation of said armature shaft of the electric motor, a second rotation signal generating means for generating a second rotation signal with phase difference from said first 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 roof position counting means for counting the first and second rotation signals generated from said first and second rotation signal generating means and the output shaft rotation signal generated from said output shaft rotation signal generating means and storing count value as position data of said sunroof lid;wherein said control unit executes an initial mode for resetting the count value of said roof position counting means to initial value when said counting value of the roof position counting means is not in a predetermined range on referring to an edge in the output shaft rotation signal generated from said output shaft rotation signal generating means.
