Abstract

PURPOSE:To control the driving speed of a wiper automatically without changing over an operating switch even with the change of the vehicle speed by providing a control unit for controlling the driving of a drive motor to increase the acting frequency of the wiper per unit time with the increase of the vehicle speed in a certain state of the operating switch. CONSTITUTION:Signals from an operating switch 10 and a speed detecting device 12 are inputted into a control unit 13. The control unit 13 then outputs such a signal as to drive a drive motor 15 to additionally increase the acting frequency of a wiper per unit time set by the operating switch 10 according to the speed increase on the basis of the inputted signal of the speed detecting device 12. Accordingly, even if the quantity of rain hitting the front glass changes according to the change of the vehicle speed, the driving speed of the wiper can be controlled automatically without operating the operating switch.

In the block diagram of an embodiment of the present invention shown in FIG. 1, 10 is an operation switch that issues a signal to drive the wiper drive motor at high speed, medium speed, low speed, and intermittently, etc., and 12 is a vehicle speed detection device. , 13 is a control device with a built-in computer, and 15 is a wiper drive motor. The control device 13 inputs a signal from the operation switch 1O and a signal from the speed detection device 12, and operates when the speed increases based on the signal from the speed detection device 12 to the number of wiper operations per unit time set by the operation switch 10. No. 48 is emitted to drive the drive motor 15 by adding up the number of times. With this speed V, the number of wiper operations per unit time n
For example, in the case of zero intermittent drive, the wiper stop time may vary linearly as shown in Fig. 2 (a), or may vary stepwise as shown in Fig. 2 (b). The speed of the wiper may be changed only, or the speed of the wiper may be changed along with this stop time.
