The invention relates to a cleaning unit for cleaning a sensor window pane of an optical sensing device of a motor vehicle. The optical sensing device can preferably be for optical distance measurement, more preferably it can be a LiDAR sensor device. The cleaning unit comprises a wiper blade. The cleaning unit further comprises at least a first scraper for scraping impediments off the wiper blade. The cleaning unit is arranged for wiping the wiper blade over the sensor window pane. The cleaning unit is further arranged for moving at least one of the wiper blade and the first scraper with respect to each other and along each other for scraping impediments off the wiper blade.

A vehicle window washer device having: a washer tank that stores washer fluid; a washer pump having one end connected to the washer tank and another end connected to one end portion of a hose; a washer nozzle connected to another end portion of the hose; a control unit that drives the washer pump to supply the washer fluid stored in the washer tank to the washer nozzle via the hose; and a supply portion that is placed in a wiping region, wiped by a wiper blade, of a windshield glass, is disposed in the washer nozzle or the windshield glass so as to not project from a wiping surface, and supplies the washer fluid from a supply port to the wiping surface.

The invention relates to a method 100 for monitoring the use of a wiper system of a motor vehicle 1, comprising the following steps: a step of collecting at least one item of data relating to the triggering of the wiper system 10, a step of collecting at least one item of data relating to the vehicle 1 and/or to its environment, a step of transforming at least one of the items of data collected in the previous steps into a value, termed monitoring value, a step of comparing the monitoring value with a value, termed predetermined threshold value, a step of recording at least one of the collected items of data when the monitoring value reaches or exceeds the predetermined threshold value.

The invention also relates to a wiper system 10 comprising a control unit designed to implement the method such as described above.

An autonomous driving sensor cleaning system for a vehicle includes a rotatable cover unit configured to surround a sensor such as a cylindrical sensor. The system also includes a cleaning unit coupled to the cover unit to transmit a rotation driving force to the cover unit and configured to clean the cover unit by friction while being rotated in a direction opposite to the rotation direction of the cover unit. The system also includes a rotation driving unit coupled to the cleaning unit and configured to transmit the rotation driving force to the cleaning unit.
