Vehicle sensor cleaning apparatus and controlling method of the same

A vehicle sensor cleaning apparatus comprising:

• a plurality of nozzles configured to spray air and/or a washer fluid onto a plurality of sensors arranged in a vehicle;
• at least one distributor configured to supply the air from an air tank and/or the washer fluid from a washer fluid tank to the plurality of nozzles, the at least one distributor including a plurality of channels, each channel connected to a respective nozzle;
• and
• a spray controller configured to control a spray of a nozzle for each channel through an on/off control of a motor of the air tank and/or a motor of the washer fluid tank and an on/off control of the at least one distributor,
• wherein the spray controller is further configured to control such that a time difference exists between an ON time of the motor of the air tank and/or the motor of the washer fluid tank and an ON time of the distributor, and the spray controller is configured to identify a delay time, which represents the time difference between the ON time of the motor and the ON time of the distributor and is defined for each channel based on hose length between the distributor and each nozzle, of the channel to which the nozzle corresponding to the sensor to be cleaned is connected, using predefined delay time for each channel, controls the motor in an ON state, and after the delay time of the corresponding channel passes, controls the distributor in an ON state.
