1. An arrangement for the automatic shifting of vehicle aggregates for the adaptation to different driving manners of drivers of motor vehicles, including a wheel slip control means for selecting permissible wheel slip settings between "select low" and "select high", and between different slippage thresholds, wherein a logic circuit means includes input means for receiving the following input signals:

  • signal A, indicating that a given value of an actuating velocity of a vehicle drive pedal was exceeded;

    signal B, indicating that a full load position of the vehicle drive pedal was reached;

    signal C, indicating that a value of a vehicle cross-acceleration calculated from a vehicle steering angle and driving speed is higher than a measured value;

    signal E, indicating that a given value of the steering angle has been exceeded; and

    wherein said logic circuit means generates from at least one of these input signals, at least one of the following output signals;

    signal W, for the shifting of the wheel slip control system from the "select low" to the "select high" operation;

    signal X, for the shifting of the wheel slip control system from a lower to a higher slippage threshold; and

    wherein said logic control means generates signal W whenever either signal A or signal B exceeds an integrated value, or when signals B and E both appear, and wherein said logic control means generates signal X when signal W and signal C appear at the same time.
