摘要： A device for estimating side slide velocity of a vehicle, comprising: a means for detecting longitudinal velocity of the vehicle body; a means for detecting yaw rate of the vehicle body about its center of gravity; a means for detecting lateral acceleration of the vehicle body at the center of gravity; and a means for integrating on time basis difference between the lateral acceleration detected by the lateral acceleration detection means and product of the yaw rate detected by the yaw rate detection means and the longitudinal velocity detected by the longitudinal velocity detection means such that only high frequency components thereof are integrated to produce a side slide velocity signal. The device may further comprise a means for estimating slip angle of at least either the front wheels or the rear wheels and converting the estimated slip angle into side slide velocity of the vehicle body at its center of gravity to produce a side slide velocity signal; and a means for summing the side slide velocity signal produced by the integration means and the side slide velocity signal produced by the slip angle estimation and conversion means to produce a final side slide velocity signal.
