Air-Guiding Device for Cooling the Brakes in a Motor Vehicle

摘要

An air-guiding device for cooling the brakes has adjustable air-guiding flaps and an electronic control unit for controlling the air-guiding flaps as a function of the vehicle speed and of the pilot control pressure, triggered by the activation of the brake pedal, in the brake system. A first mode and a second mode for opening the air-guiding flaps are provided in the control unit by a corresponding program module. The first mode is directed to a strong deceleration demand at a relatively high vehicle speed, in particular on freeways and country roads. The second mode is directed to an acceleration prevention demand at a relatively low vehicle speed, in particular when travelling downhill on roads through mountain passes.

主权项

1. An air-guiding device for cooling brakes in a motor vehicle, comprising:
adjustable air-guiding flaps configurable to direct air to the brakes in the motor vehicle; an electronic control unit operatively coupled with the adjustable air-guiding flaps, the electronic control unit controlling the adjustable air-guiding flaps as a function of vehicle speed and as a function of pilot control pressure generated in a brake system upon activation of a brake pedal, wherein the electronic control unit is programmably configured to control the adjustable air-guiding flaps in a first mode and a second mode, the first mode being designed for a strong deceleration demand at a relatively high vehicle speed and the second mode being designed for an acceleration prevention demand at a relatively low vehicle speed.
