Radar cleaning method and device and radar equipment

The embodiment of the invention provides a radar cleaning method and device and radar equipment, and the method comprises the steps: generating a cleaning task according to a radar pollution signal and a current vehicle speed signal of a vehicle; according to the cleaning task, a driving device is controlled to work so as to drive cleaning equipment to move; and when the flow outlet of the cleaning equipment reaches the preset flow outlet starting position and the cleaning direction of the cleaning equipment coincides with the preset cleaning direction, a cleaning water pump is controlled to work, so that the cleaning equipment conducts cleaning operation on the to-be-cleaned area on the surface of the radar. According to the method, the operation position of the cleaning equipment is optimized according to the to-be-cleaned area, the utilization rate of the cleaning liquid is greatly improved, the influence of the pollution position, the incoming flow speed, the incoming flow direction and other factors on t
