1. A device for detecting a pendulum motion of a vehicle, comprising:

  • at least one first ascertainment means for ascertaining at least one lateral-motion-dynamics quantity that represents a lateral motion dynamics of the vehicle;

    second ascertainment means for ascertaining a speed quantity that describes a vehicular speed;

    third ascertainment means for determining, as a function of the at least one lateral-motion-dynamics quantity and the speed quantity, whether a pendulum motion of the vehicle exists, wherein, in determining whether a pendulum motion of the vehicle exists, it is checked whether the at least one lateral-motion-dynamics quantity is greater than an associated first threshold value and it is checked whether the speed quantity is greater than an associated second threshold value, a pendulum motion of the vehicle existing when the at least one quantity is greater than the first threshold value, and when the speed quantity is greater than the second threshold value; and

    at least one of, a first detection means for detecting a lateral acceleration acting on the vehicle, one of the at least one first ascertainment means ascertaining one of the at least one lateral-motion-dynamics quantity as a function of the lateral acceleration of the vehicle; and

    a second detection means for detecting a yaw rate of the vehicle, one of the at least one first ascertainment means ascertaining one of the at least one lateral-motion-dynamics quantities as a function of the yaw rate of the vehicle;

    wherein the at least one first ascertainment means includes precisely two first ascertainment means, the two first ascertainment means being one first detection means and one second detection means.
