Development of Rain Sensor for Automatic Wiper System 2001-01-0612

One of the key elements of vehicle safety requires a constantly uninterrupted visible view especially during unexpected weather conditions.
Our present development of a light reflection type rain sensor is a key device of our automatic windshield wiper system. The design concept of the sensor is based on the quantification on both detected rainfalls and wiping modes in order to match the wiping mode in an operator's mind by optimizing the optical sensing system and establishing an algorithm for controlling wiping. In addition, auto-initialization of the system has been achieved first in the world.
