Abstract
A system includes a sensor base, a sensor cover having a window that is rotatably mounted to the base. The system includes a contacting cleaner and a contactless cleaner. The system further includes a processor that is programmed to actuate, first, the contactless cleaner and, then, upon determining that opacity of the window exceeds a predetermined threshold after actuation of the contactless cleaner, the contacting cleaner.
Claims17
A system, comprising:
- a computer that includes a processor and a memory, the memory storing instructions such that the processor is programmed to:
- actuate, first, a contactless cleaner upon determining that an opacity of a window of a cover of a sensor exceeds a first predetermined threshold, and, then, after actuation of the contactless cleaner and upon determining that opacity of the window exceeds a second predetermined threshold that is different than the first predetermined threshold, a contacting cleaner;
- determine a change in a rotational speed of the cover upon actuation of the contacting cleaner;
- and
- cause an adjustment to interpretation of data from the sensor according to the changed rotational speed.
