The wiper motor 1 is intermittently controlled by bringing it into contact with the make contact shown.

The wiper motor 1 also has an automatic stop contact (AS) 23 built therein. When the wiper blade is operating away from the blade stop position, the auto stop contact 23 is in an ON state in which the central movable contact is connected to the make contact indicated by a white circle as described later in the timing chart of FIG. As a result, the operation of the wiper motor 1 is self-maintained, and when the wiper blade comes to the blade stop position, the central movable contact is brought into the off state connected to the break contact indicated by the black circle. ing. The purpose of the auto-stop contact 23 that performs such an operation is that even when the wiper switch 5 is operated in the off state while the wiper blade is operating in the middle of the windshield, the auto-stop contact 2
3 allows the operation of the wiper motor 1 to be continuously self-maintained, thereby moving the wiper blade to the blade stop position and then stopping the operation of the wiper motor 1.

Next, the operation of the wiper operation control device constructed as described above when the wiper blade operates at high speed will be described.

As a result, the wiper blade operates on the windshield at a low speed from the blade reversal position to the blade stop position. This low speed operation state is self-maintained by the auto stop contact 23.

In this way, when the wiper blade operates at a low speed from the blade reversal position toward the blade stop position and the wiper blade reaches the blade stop position, the auto stop contact 23 is turned off as shown in FIG. 2 (d). As a result, the wiper motor 1 stops and the wiper blade stops at the blade stop position.

Further, as described above, when the blade position detecting means 7 detects that the wiper blade has reached the blade stop position and the blade stop position detection signal is input to the judgment circuit 9, the judgment circuit 9 , The timer 25 is driven in response to the blade stop position detection signal,
Starts counting a predetermined intermittent down time. During this intermittent down time, the wiper motor 1 is stopped and the wiper blade is also stopped at the blade stop position.

Moves the wiper blade at a low speed. Then, when the wiper switch 5 is returned from the ON state of the wiper blade intermittent operation contact (INT) to the OFF state as shown in FIG. 2A, the wiper blade comes to the blade stop position, and the auto stop contact 23 is turned off. , The wiper motor 1 is stopped, and the operation of the wiper blade is stopped.

In the above operation, the wiper blade is

When the wiper blade moves from the blade reversal position to the blade stop position, the wiper blade operates at a low speed, so that raindrops attached to the wiper blade are not scattered.

In the present embodiment, the wiper motor 1 is switched from the high speed operation to the low speed operation after the blade position detecting means 7 detects that the wiper blade has reached the blade reversal position. The detection means 7 detects that the wiper blade has arrived shortly before the blade reversal position, and the detection signal causes the wiper motor 1 to switch from high speed operation to low speed operation when the wiper blade reaches shortly before the blade reversal position. The wiper motor can be smoothly and easily switched from the high speed operation to the low speed operation by controlling in this way.
