Screen wiper

The screen wiper drive is in the tank under a windscreen. A screen wiper and стеклоомыватель cope the electronic module depending on speed of the car.

On the standing car speed of work of a screen wiper decreases.

With increase in speed of the car intervals of work of a screen wiper decrease.

At will the automatic interval operating mode can be established. Device AIC (Automatic control of intervals) has the rain gauge and operates intervals depending on humidity of a windscreen. The rain gauge measures humidity of a windscreen at the expense of reflexion of the infra-red light radiated by the light diode. Dry glass completely reflects infra-red light, damp reflects partially.
