The invention relates to a cleaning unit for cleaning a sensor pane of an optical sensor device of a motor vehicle, in particular for optical distance measurement, more in particular lidar sensor devices. The cleaning unit includes a wiper. Furthermore, the cleaning unit comprises a drive unit arranged to cause the wiper to wipe on the sensor glazing. Advantageously, the cleaning unit may be arranged for wiping a first portion of the wiper, such as for example a first wiper tip, on the sensor glazing from a first position towards a second position, such as to wipe at least a first portion of the sensor glazing located between the first position and the second position. The cleaning unit may then be further arranged to move the wiper back from the second position substantially towards the first position, and the first portion of the wiper does not wipe over the first portion of the sensor glazing.
本发明涉及一种用于清洁机动车辆的光学传感装置的传感器窗玻璃的清洁单元,光学传感装置特别是用于光学距离测量,更特别是激光雷达传感器装置。清洁单元包括擦拭器。此外,清洁单元包括驱动单元,驱动单元被布置用于使擦拭器在传感器窗玻璃上擦拭。有利地,清洁单元可以被布置用于使擦拭器的第一部分、诸如像第一擦拭器末端,在传感器窗玻璃上从第一位置朝向第二位置擦拭,诸如用以擦拭传感器窗玻璃的位于所述第一位置与所述第二位置之间的至少第一部分。然后,清洁单元还可以被布置用于使擦拭器从所述第二位置基本上朝向所述第一位置向回运动,且擦拭器的所述第一部分不在传感器窗玻璃的所述第一部分上擦拭。
