Abstract

바퀴 속도 센(8-11)와, 핸들각 센서(19)와, 만일 적절하다면 편요-속도센서(18)와 그리고 또 다른 센서로부터의 신호가 제어 유니트(12)에 의해 평가된다.The signals from the wheel speed sen (8-11), the handle angle sensor (19) and, if appropriate, the yaw-rate sensor (18) and another sensor are evaluated by the control unit (12).

제어 유니트(12)는, 자동차(1)의 개개의 바퀴(4-7)상에 작동하는 브레이크 압력을 안정된 자동차(1) 구동 상태에서 제어하는 동작 신호를 발생시킨다. 이것은 예를 들어, 브레이크가 로크되지 않고, 바퀴가 활주하지 않으며, 자동차가 일탈하지 않는 것등을 의미한다. 제어 유니트(12)는 에어백 제어기(17)에 연결되고 에어백 제어기의 가속도 센서(16)로부터의 신호를 평가한다. 편의상, 편요-속도 센서(18)와, 가속도 센서(16)와 에어백 제어기(17)가 자동차의 중심에 배열되는 하우징(14)내에 함께 수용된다. 더욱이, 활동 충격 흡수기 및 조종 가능한 뒤 차축이 제어될 수 있고 구동 상태에 엔진 토크를 맞추기 위하여, 예를 들어 활주하고 있는 피구동 바퀴의 경우에 일시적으로 감소시키기 위하여 자동차의 엔진 제어기를 간섭할 수도 있다.The control unit 12 generates an operation signal for controlling the brake pressure operating on the individual wheels 4-7 of the automobile 1 in a stable driving state of the automobile 1. [ This means, for example, that the brakes are not locked, the wheels do not slide, the car does not deviate, and so on. The control unit 12 is connected to the airbag controller 17 and evaluates the signal from the acceleration sensor 16 of the airbag controller. For convenience, a yaw-rate sensor 18, an acceleration sensor 16 and an airbag controller 17 are housed together in a housing 14 arranged at the center of the vehicle. Moreover, the active shock absorber and the steerable rear axle may be controlled and may interfere with the engine controller of the vehicle to temporarily reduce the engine torque in the driving state, for example in the case of a sliding driven wheel .
