Automatic control equipment for cleaning a plate surface exhibiting varied soiled conditions , and use method
First Claim
1. Automatic control equipment for cleaning a plate surface exhibiting varied soiled conditions, comprising at least a light source (1, 1a), an opaque stain channel, an aqueous stain channel and at least an optical detector (2, 2a) with independent photosensitive element, the source (1, 1a) and the optical detectors being arranged on a support on the side of the inner surface (10a) of the windscreen (10) to be cleaned, characterized in that the optical detectors (2, 2a) are at a distance from the source (1, 1a) based on backscatter angles (C, D) of the opaque stains and reflection (A, B) of the aqueous stains, an electronic processing unit (4) comprising a multiplexing block (3) and a microcontroller (5), is coupled in input with the optical detector channels, and in output with a control unit (6) for the wiper and windshield washer of the surface (10) to be cleaned.

Abstract
The invention concerns an equipment for cleaning a motor vehicle windshield comprising at least a light source (1), an opaque stain channel, an aqueous stain channel and at least an optical detector (2b) of ambient light, each stain channel comprising at least an optical detector (2) with independent photosensitive element, the source (1) and the optical detectors (2) being arranged on a support on the side of the inner surface (10a) of the windshield (10) to be cleaned. The optical detectors (2) are at a distance from the source (1) based on backscatter angles (C, D) of the opaque stains and reflection (A, B) of the aqueous stains. An electronic processing unit (4) comprising a multiplexing block (3) and a microcontroller (5), is coupled in input with the optical detector channels, and in output with a control unit (6) for the wiper and windshield washer of the surface (10b) to be cleaned.
