Vehicle cleaning system

The invention discloses a vehicle cleaning system. The vehicle cleaning device comprises a water tank, a liquid driving device, a manifold valve module, a cleaning controller, and a liquid nozzle, thecleaning controller receives a cleaning instruction sent by an electronic control unit, determines a to-be-cleaned object according to the cleaning instruction, and controls liquid channel cleaning operation, specifically, the manifold valve module is controlled to open a branch liquid flow channel corresponding to the to-be-cleaned object, the liquid driving device is controlled to operate, so that cleaning liquid in the water tank flows in a liquid channel pipeline and is sprayed on the to-be-cleaned object through the liquid driving device, the manifold valve module, and the liquid nozzlecorresponding to the to-be-cleaned object, and the cleaning effect is ensured. Thus according to the vehicle cleaning system, cleaning of cleaning objects increasingly added in a vehicle system, suchas sensors and cameras, is
