Technical Field

The invention relates to an automatic driving technology, in particular to a heatable sensor cleaner and an automobile.

Background

With the increasing maturity of automatic driving technology, the demand for vehicle-mounted sensors is more and more, and the dependence of automatic driving vehicles on the sensors is higher and higher. Sensors such as cameras and lidar require a clean sensor surface for normal operation, and contamination of the sensor surface may cause a decrease in the detection capability of the sensor, and in severe cases may even cause a failure of the detection function of the sensor, which undoubtedly brings a great risk to automatic driving. Therefore, cleaning of the sensor becomes especially important.

The conventional cleaning is more water washing by means of spraying a cleaning liquid, and the cleaning is effective for general vehicle lamp cleaning or cleaning of local exterior trim, but has certain defects for cleaning of a sensor. The sensor, especially the vision sensor, such as a camera, a depth camera, a night vision camera, a laser radar, etc., the water drops condensed on the sensor surface can affect the detection quality, which brings the problems of increased detection misjudgment, increased noise, limited detection distance, etc. In addition, in the case of snow or frost in winter and during driving in rainy days, the manner of spraying the cleaning liquid does not allow the cleaning function to be performed, and even aggravates the detection problem of the sensor.
