A kind of control device reducing vehicle air resistance coefficient

The invention discloses a kind of control devices for reducing vehicle air resistance coefficient, are related to vehicle structure field.The control device includes resistance-reducing device and control unit.Resistance-reducing device is mounted at the preceding face of vehicle, for being unfolded or packing up according to driving cycle.Control unit is connected with vehicle-mounted electronic control unit, for acquiring the current driving information of vehicle and being pocessed.When vehicle high-speed operation, control resistance-reducing device is unfolded to form air deflector at the preceding face of vehicle, to reduce air resistance coefficient of the vehicle in high-speed cruising.When the operation of vehicle low speed, control resistance-reducing device is packed up, to restore original moulding of vehicle, wherein the vehicle remains static or when low-speed run state, and resistance-reducing device is in collapsed state.The present invention changes simultaneously before vehicle that gas flowfield is distributed at face by changing vehicle moulding to prevent vehicle front air-flow from entering in vehicle vehicle cover by engine radiating grid, effectively reduces air resistance coefficient of the vehicle in high-speed cruising.
