Vehicle camera cleaning system

摘要

Embodiments provide vehicle camera cleaning systems used for cleaning foreign matter off of a camera lens, including, for example, a water flow nozzle arranged to eject water flow, an air nozzle arranged to eject air, and a central controller used to control the water flow nozzle and air nozzle. In certain embodiments, a plurality of sensing devices are used for sensing the conditions of the camera lens, such as an infrared water drop sensor, a temperature sensor, a camera sensing sensor, and the like. The central controller may determine whether there are water drops, ice, snow, or other foreign matter on the lens based on signals received from the plurality of sensing devices, and may control the air nozzle and the water flow nozzle to clean the camera lens based on the foreign matter present.

主权项

1. A vehicle camera cleaning system, comprising:
a water flow nozzle arranged proximate to a camera lens, the water flow nozzle being configured to spray water onto the camera lens; an air nozzle arranged proximate to the camera lens, the air nozzle being configured to expel air onto the camera lens; a water drop sensor comprising an infrared emitter and an infrared receiver, wherein the water drop sensor is configured to generate and transmit water drop sensor information indicating a percentage of infrared rays emitted by the infrared emitter that are received by the infrared receiver; a central controller comprising a processing unit including one or more processors, the central controller configured to control the operation of the air nozzle, wherein the central controller is further configured to:
receive the water drop sensor information from the water drop sensor;determine whether there are water drops on the camera lens based on the water drop sensor information;in response to determining there are water drops on the camera lens, generate an instruction to activate the air nozzle to expel air onto the camera lens to remove the water drops;after the air nozzle has expelled air onto the camera lens, receive the water drop sensor information from the water drop sensor and determine whether there are residual water drops remaining on the camera lens based on the water drop sensor information; andin response to determining there are residual water drops on the camera lens, generating an activation instruction to activate the water flow nozzle to remove the residual water drops.
