Improved sensor cleaning based on required cleaning intensity

A sensor cleaning device for cleaning an exterior sensor surface of a sensor including one of an optical camera or a LiDAR, for use in automotive applications, the sensor cleaning device comprising:

• multiple wiper elements;
• and
• a wiper rig, which supports the multiple wiper elements, and which is movable to move the multiple wiper elements across an exterior sensor surface, wherein:
• the sensor cleaning device is adjustable to adjust a cleaning intensity for cleaning the exterior sensor surface based on a required cleaning intensity for cleaning the exterior sensor surface, and
• the sensor cleaning device comprises positioning means for positioning the multiple wiper elements relative to the exterior sensor surface based on a required cleaning intensity for cleaning the exterior sensor surface,
• the positioning means enable a movement of the multiple wiper elements in a direction of a z-axis perpendicular to the exterior sensor surface, and
• wherein;
• the positioning means include multiple positioning means for individually positioning each wiper element of the multiple wiper elements relative to the exterior sensor surface based on the required cleaning intensity for cleaning the exterior sensor surface, and
• the positioning means are for commonly positioning the wiper elements relative to the exterior sensor surface based on the required cleaning intensity for cleaning the exterior sensor surface and the wiper rig comprises adjusting means for adjusting a position of the multiple wiper elements relative to the exterior sensor surface and relative to each other based on the required cleaning intensity for cleaning the exterior sensor surface.
