Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile sunroof drive control device, and more particularly to an automobile sunroof drive control device which is interlocked with a wiper.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional example. The conventional example shown in FIG. 6 includes a wiper system 20 for controlling the wiper and a sunroof system 30 for controlling the opening / closing of the sunroof.

Here, the wiper system 20 has a wiper switch 21 which is on / off controlled by a driver, a wiper relay 22 which outputs a signal according to an on / off state of the wiper switch 21, and a signal from the wiper relay 22. And a wiper motor 23 for driving the wiper.

The sunroof system 30 includes an open switch 31 which is depressed when the driver opens the sunroof, a close switch 32 which is depressed when the driver closes the sunroof, and a sunroof fully closed. A closed limit switch 33 for detecting the state, an open limit switch 34 for detecting the fully open state of the sunroof, a microcomputer 35 for outputting a sunroof control signal based on the state of each switch, and a control signal from the microcomputer 35. Sunroof control relay 36 that outputs a drive signal based on the sunroof control relay 3
The sunroof motor 37 drives the sunroof on the basis of the drive signal from the sunroof 6.

Since the wiper system 20 and the sunroof system 30 are independently configured, the sunroof is opened and closed only by the driver operating the sunroof opening / closing switches 31 and 32, and the wiper is operated by the driver. It operates only by turning the switch 21 on and off.

Therefore, when it suddenly rains, the driver needs to turn on the wiper switch 21 to move the wiper and press the closing switch 32 to close the sunroof.

That is, as shown in the timing chart of FIG. 7, even if it starts to rain and the wiper switch 21 is turned on, the interior of the vehicle is kept for a time A until the close limit switch 33 is turned on by pressing the close switch 32. There was rain infiltration.

[0008]

However, in the above-mentioned conventional example, since the wiper system and the sunroof system are independent of each other, when the rain occurs, as shown in FIG. The switch and the closing switch have to be operated, which is complicated, and there is a disadvantage that rain falls into the vehicle due to the delay in the operation of the closing switch.

Further, when the sunroof is composed of, for example, a manual sunshade and an electric moonroof, if the inner sunshade is closed, the open / closed state of the outer sunroof becomes unclear, so that it rains. Even if I started, I forgot to close the moon roof, and the sunshade delays the entry of rain into the car, so when the driver notices that the moon roof is open, there is considerable rain around the sun roof. There was a problem.

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sunroof drive control device for an automobile, in which the disadvantages of the conventional example are improved, and in particular, a wiper system and a sunroof system are linked.
