Abstract

<P>PROBLEM TO BE SOLVED: To reduce a pinching load during a tilt-closing motion of a roof opening/closing body by changing torque during the tilt-closing motion, without the use of an oscillation device for oscillating a voltage input into a motor part. <P>SOLUTION: A sunroof opening/closing control unit 10 brings about the tilt-closing motion of a roof opening/closing body 86 by the switching and rotational drive of the first and second motor parts 20 and 22 different in output torque from each other. Thus, the torque during the tilt-closing motion of the roof opening/closing body 86 can be changed without the use of the oscillation device for oscillating the voltage input into the first and second motor parts 20 and 22. Additionally, the second motor part 22 with low output torque makes the tilt-closing motion of the roof opening/closing body 86, until a traveling speed of a vehicle 80 reaches a predetermined speed (100 km/h). This enables a reduction in the pinching load during the tilt-closing motion of the roof opening/closing body 86. <P>COPYRIGHT: (C)2007,JPO&INPIT

It is determined whether 86 has reached the fully closed tilt position (step S16). At this time, when the control unit 56 determines that the roof opening / closing body 86 has not reached the tilt fully closed position (step S16: NO), the control unit 56 returns to the process of step S11.
