Optically actuated automatic control system for windshield wiper of vehicles, has controller regulating actuation of wiper, when image intensity variance parameter output by signal processor exceeds threshold value
Optically actuated automatic control system for windshield wiper of vehicles, has controller regulating actuation of wiper, when image intensity variance parameter output by signal processor exceeds threshold value
A photographic device (1) acquires predetermined set of windshield image data. A signal processor (2) processes the image data to generate an image intensity variance parameter and another parameter indicative of windshield obscuration. A controller (3) regulates actuation of wiper of windshield clearing subsystem, when the variance parameter exceeds the predetermined threshold value.
