The air-guiding device according to the invention for cooling the brakes basically has adjustable air-guiding flaps and an electronic control unit for controlling the air-guiding flaps as a function of the vehicle speed and as a function of the pilot control pressure generated in the brake system owing to the brake pedal actuation. In the control unit, a first mode and a second mode for the opening of the air-guiding flaps are provided by means of a corresponding programme module. The first mode is designed for an intense deceleration demand at relatively high vehicle speed - in particular on motorways and highways. The second mode is designed for an acceleration prevention demand at relatively low vehicle speed - in particular when travelling downhill on mountain passes. |
