Automatic driving vehicle camera cleaning system

Abstract

The present application discloses an autonomous vehicle camera cleaning system, comprising: a housing as a support member of the cleaning system; the optical window is arranged at the front part of the shell, is provided with a rotation axis, and is rotationally arranged at the front part of the shell around the rotation axis of the optical window; the camera is arranged in the shell and coincides with the rotation axis of the optical window, and the camera faces a road scene where the optical window and the camera jointly participate in imaging; and the rotary cleaning mechanism is arranged in the shell, is relatively separated from the camera and is used for driving the optical window to rotate at a high speed relative to the camera at the front part of the shell so as to clean the surface of the optical window through a centrifugal effect. The camera and the rotary cleaning mechanism are relatively separated, the structure is simple and reliable, the number of parts is small, the universal sensor cleaning scheme of various cameras with different performance and size requirements can be rapidly adapted, and therefore the adaptability of the scheme is improved while the cleaning capacity is guaranteed.

Description

technical field [0001] The present application relates to the field of automatic driving, and in particular, to a camera cleaning system for an automatic driving vehicle. Background technique [0002] In recent years, technologies such as autonomous driving and assisted driving have attracted the attention of the industry, and have been developed and widely used. Cameras are one of the core sensors required for these technologies and applications. However, in actual use, rain, fog, dust, debris, or other pollutants will adhere to the camera, affecting the camera's field of view and clarity, which in turn will affect the corresponding automatic driving / assisted driving functions. In severe cases, the entire function may be disabled, endangering the safety of passengers and vehicles. [0003] In the prior art, high-speed rotation technology is often used to clean the surface of the camera. This technology realizes the high-speed rotation of the camera lens by integrating or i...

Problems solved by technology

However, in actual use, rain, fog, dust, debris, or other pollutants will adhere to the camera, affecting the camera's field of view and clarity, which in turn will affect the corresponding automatic driving / assisted driving functions. In severe cases, the entire function may fail, endangering the safety of passengers and vehicles

[0003] In the prior art, high-speed rotation technology is often used to clean the surface of the camera. This technology realizes the high-speed rotation of the camera lens by integrating or installing the camera on the internal spindle of the motor, or wraps the camera as a whole in the transmission mechanism, and The mechanism is relatively complicated. When there is a problem with the camera or the mechanism, the entire system may need to be replaced, and the cost and cost of replacement and repair are relatively high
