Abstract

The present invention relates to a sensor cleaning system for a vehicle, and more specifically, to a sensor cleaning system having an anti-freezing and thawing function in an air injection type sensor cleaning system. According to an embodiment of the present invention, the sensor cleaning system for a vehicle comprises: a distributor having a channel into which compressed air is introduced and a plurality of outlets, for distributing compressed air from the channel to each outlet; a valve formed integrally with the distributor and capable of opening and closing to allow or block the supply of compressed air through each outlet; a heating element configured to apply heat to the distributor; and a controller configured to operate the heating element when a preset condition is achieved.
