    • A difference .delta..sub.2 -.delta..sub.1 is formed between the steering angle .delta..sub.2 actually measured and the steering angle .delta..sub.1 calculated from the vehicle transverse acceleration, vehicle speed, and a series of constants. This difference (.delta..sub.2 -.delta..sub.1) is used to displace the working point on the .mu.-slip curve in the direction of an increase of the lateral stability, i.e., toward smaller slip values. Response can be improved by making the displacement also dependent on the rate of change of this difference or the rate of change of the actual steering angle. Preferably no reaction is produced when the difference is below a threshold angle unless one of the rates exceeds a respective threshold.
    • 在实际测量的转向角Δ2与从车辆横向加速度,车辆速度和一系列常数计算出的转向角delta 1之间形成差异Δ2-δ1。 该差值(δ2-δ1)用于沿着横向稳定性增加的方向(即向较小的滑移值)移动μ-滑动曲线上的工作点。 通过使位移也取决于该差异的变化率或实际转向角的变化率,可以改善响应。 优选地,当差值低于阈值角时,不产生任何反应,除非速率之一超过相应的阈值。

    • A thyristor having a common-anode main thyristor and auxiliary thyristor combination integrated in a semiconductor chip with at least four alternating zones of different conductivity types. A first control electrode contacts a small-area control zone recessed in an emitter region. A first ring zone which is at least as highly n-doped as an emitter zone is disposed in the recessed control zone and is partially contacted by a second control electrode, as is also a portion of a p-doped base zone emerging at various places on the chip surface, the p-doped base zone forming a shorted auxiliary emitter. The second control electrode as well as the first control electrode, have leads separately brought out of the thyristor case, as are leads connected to a main cathode terminal and an auxiliary cathode terminal. The second control electrode together with the auxiliary cathode terminal can be used as a trigger-pulse source, or the second control electrode can alone be used as the trigger input to the thyristor.
