Abstract

The invention relates to a cleaning apparatus (9) for cleaning a transparent front element (11) of an optical sensor (4) for a motor vehicle (1), including the transparent front element (11) and including a light source (13) for externally illuminating the front element (11) with light beams (14), including a detector device (18) for receiving the light beams passed through the front element (11),and including an evaluation device (19), which is formed for evaluating the light beams received by the detector device (18) for determining a degree of contamination of the front element (11), wherein a control signal (22) for a cleaning device (10) of the cleaning apparatus (9) is generable depending on the evaluation such that the front element (11) is cleanable by means of the cleaning device(10). Further, the invention relates to an assembly (32) and to a method.

Description

technical field [0001] The invention relates to a cleaning device for cleaning a transparent front element of an optical sensor of a motor vehicle. Furthermore, the invention relates to an assembly as well as a method. Background technique [0002] Detector arrangements for receiving light beams for motor vehicles are known from the prior art. They include transparent front elements. Especially in applications at motor vehicles, contamination may occur on the transparent front element. Impairment of the information received by the detector device may occur due to contamination. In order to be able to restore the functionality of the detector arrangement it is necessary to clean the transparent front element. Currently, such contamination is known to take place, for example, by manually activating liquid and / or air cleaning systems. [0003] Systems are known from the prior art which can detect the degree of contamination by means of wavelength analysis. For example, US...
