Sensor cleaning system with anti-freezing function

A sensor cleaning system for a vehicle, the system comprising:

• a distributor having a channel into which compressed air is introduced and having a plurality of exits, the distributor configured to distribute the compressed air from the channel to each exit of the plurality of exits;
• a plurality of valves formed integrally with the distributor, each valve capable of being selectively opened or closed to allow or prevent a supply of the compressed air through a respective one of each of the plurality of exits;
• a heating element configured to apply heat to the distributor and disposed to surround the distributor;
• a controller configured to operate the heating element based on a determination that a preset condition is satisfied;
• and
• a temperature sensor disposed on the distributor configured to detect a temperature of the distributor and to transmit the detected temperature to the controller,
• wherein the controller is configured to operate the heating element based on a determination that a change in pressure of the distributor is less than a preset minimum value at the time of one of the plurality of valves being opened.
