Abstract
A wiper control system controls an automotive wiper in accordance with rain conditions. Rain conditions are detected by means of a rain sensor which has a vibrator adapted to vibrate at an amplitude corresponding to rain conditions. The vibrator is adapted to produce a sensor signal having an amplitude corresponding to its vibration. The vibrator vibrates at a resonant frequency outside of the audible frequency range and has adequate sensitivity for detecting rain conditions.
