Windscreen-washing device for a sealing pane on a driver-assistance system for a motor vehicle's front area has an optical sensor

摘要

A sealing pane's outer side has a nozzle (4) to create a spray cone (5) from a washing liquid. Directed onto the external side of the sealing pane, the spray cone consists of water droplets. The nozzle has optically active penetrating areas (OAPA) (2,3) of different sizes for an optical sensor. The smaller OAPA fits next to the nozzle and the larger OAPA furthest from the nozzle.
