The invention relates to an active jet flow resistance reduction control system and method for an automobile wheel area. The system comprises a signal receiving and processing unit, a jet flow resistance reduction unit and a central control unit, the signal receiving and processing unit comprises at least two pressure sensors, receives a vehicle speed signal and an incoming flow pressure signal, calculates an incoming flow side slip angle according to the incoming flow pressure signal, and transmits the incoming flow side slip angle to the central control unit; a vehicle speed signal and an incoming flow slip angle signal are sent to the central processing unit, the central processing unit adjusts a jet flow momentum coefficient and a jet flow angle after receiving the signals and sends corresponding control signals to the jet flow resistance reduction unit, and the jet flow resistance reduction unit comprises a plurality of jet flow grooves and corresponding jet flow exciters. The multiple jet flow grooves are formed in the sides, close to the ground, of all wheel cavities of the vehicle correspondingly, and steady jet flow is applied according to the received control signals for drag reduction. Compared with the prior art, the invention has the advantages that the aerodynamic resistance of the wheel part of the vehicle is effectively reduced, the net energy conservation of the vehicle is realized, and the aerodynamic resistance of the whole vehicle is further reduced.
