The invention relates to a method and a device for ascertaining whether there is a forward motion or a backward motion of a vehicle, wherein a forward motion variable is ascertained by means of a mathematical forward motion relation for at least two wheels of the motor vehicle, said mathematical forward motion relation describing the forward motion; ascertaining a backward motion variable by means of a mathematical backward motion relation for the same wheel of the motor vehicle, said mathematical backward motion relation describing a backward motion; ascertaining a dispersion range of the forward parameter and a dispersion range of the backward parameter; and if the dispersion range of the forward parameter is smaller than the dispersion range of the backward parameter, determining that the forward is present; and if the dispersion range of the backward movement parameter is smaller than the dispersion range of the forward movement parameter, determining that the backward movement is present.

    本发明涉及用于查明是存在车辆的前行还是存在车辆的倒行一种方法和一种装置,其中‑借助于用于所述机动车的至少两个车轮的描述前行的数学的前行关系式来分别查明前行参量;‑借助于用于所述机动车的相同车轮的描述倒行的数学的倒行关系式来分别查明倒行参量;‑查明所述前行参量的分散范围和所述倒行参量的分散范围;并且‑如果所述前行参量的分散范围小于所述倒行参量的分散范围,则将前行确定为存在;并且‑如果所述倒行参量的分散范围小于所述前行参量的分散范围,则将倒行确定为存在。
