1. An arrangement for performing a plausibility check of a rollover decision in a motor vehicle, comprising:

  • an arrangement including at least one of at least one yaw rate sensor and at least one acceleration sensor and for detecting a movement of the vehicle, the arrangement providing a sensor signal;

    a processor for deriving a decision from the sensor signal as to whether the vehicle movement will result in a rollover; and

    an arrangement for producing, from a measured acceleration in a direction of a vertical axis of the motor vehicle and a measured acceleration in a direction of a transverse axis of the motor vehicle, a criterion for performing the plausibility check of the rollover decision which has been made, wherein;

    the arrangement for producing the criterion signals the plausibility of the rollover decision if one of the following is true;

    if the measured acceleration in the direction of the vertical axis is one of greater than a preset upper threshold and less than a preset lower threshold, and if the measured acceleration in the direction of the vertical axis is between the preset upper threshold and the preset lower threshold and the measured acceleration in the direction of the transverse axis simultaneously exceeds a threshold that depends on the measured acceleration in the direction of the vertical axis.
