1. device that is used for determining the situation of rocking of vehicle, described device comprises:

  • First accelerometer is used for sensing basically not only perpendicular to the vertical axle of vehicle but also perpendicular to the acceleration on the Z-direction of the axle from a side to opposite side of vehicle and be used to provide first acceleration signal of the acceleration on this Z-direction of indication;

    Second accelerometer is used for sensing at the acceleration on parallel with the described vertical axle of the vehicle basically X-direction and be used to provide second acceleration signal of the acceleration on this X-direction of indication;

    WithController is used for determining Z axle velocity amplitude according to first acceleration signal, and the two determines the situation of rocking of vehicle in response to the Z axle velocity amplitude of determining and second acceleration signal.
