RAIN SENSING WIPER
The rain sensing wiper unit in this vehicle doesn't control the wiper directly.
The rain sensing unit detects the amount of rain drops and sends the operating signal to
STICS, and STICS drives the wiper directly.
1. COMPONENTS OF RAIN SENSOR
Rain sensing unit
A sensor that emits infrared rays through LED
and then detects the amount of rain drops by
receiving reflected rays against sensing
section(rain sensor mounting section on the
windshield)with photodiode.
The rain sensing unit detects the
STICS
amount of rain drops and sends the
operating signal to STICS, and
STICS drives the wiper directly.
At this moment, STICS determines
the wiper operation mode (washer,
MIST, AUTO), then sends the
information to the rain sensor.
