Device for controlling automatic operation of a windshield wiper with improved control means for setting rain sensor sensitivity
First Claim
1. A device for controlling automatic operation of a windshield wiper in a motor vehicle, said control device comprisinga central electronic control unit (10) including means for triggering wiping operations of the windshield wiper (13);
- a rain sensor (20) including means for detecting rain on the windshield and means for generating sensor signals (22) for the triggering of individual ones of the wiping operations, said rain sensor (20) being connected to said control unit (10) in order to furnish said sensor signals (22) to said control unit (10); and
sensitivity control means (14) for adjusting rain sensor sensitivity of said rain sensor (20), said control means (14) including at least one display for observing said rain sensor sensitivity or parameters controlling said rain sensor sensitivity optically and buttons (18) operable to adjust said rain sensor sensitivity or at least one of said parameters controlling said rain sensor sensitivity.
