摘要： A vehicle supercharging system and a control method thereof are disclosed. The vehicle supercharging system includes: an engine generating power according to combustion of a fuel; a transmission including at least one friction clutch; an electric supercharger that compresses air by rotational force of a motor; an engine-side supercharging path part branching from an air supplying line that supplies air to the engine, passing through the electric supercharger, and joining the air supplying line; a transmission-side supercharging path part that sucks air separately from the engine-side air supplying line, passes through the electric supercharger, and supplies compressed air to the transmission; and a controller that operates the electric supercharger according to a driving state of a vehicle and that controls the engine-side supercharging path part for boosting the engine and the transmission-side supercharging path part for cooling or warming the transmission through control of valves.
