The invention relates to a vehicle speed estimation method under driving and emergency braking working conditions. The method comprises the steps that according to the wheel speed of each wheel of a vehicle, the axial center line speed corresponding to each wheel is determined, according to each axial center line speed and the braking condition of a driven wheel in each wheel, the first axial center line speed is determined, and according to the first axial center line speed, the longitudinal speed of the vehicle is estimated; wherein the longitudinal speed is the speed in the direction parallel to the running direction of the vehicle. By adopting the method, the accuracy of estimating the longitudinal speed of the vehicle can be improved.

    本申请涉及一种驱动与紧急制动工况的车辆速度估计方法。所述方法包括:根据车辆各车轮的轮速,确定各所述车轮对应的轴中心线速度,根据各所述轴中心线速度和各所述车轮中从动轮的制动情况,确定第一轴中心线速度,根据所述第一轴中心线速度,估计所述车辆的纵向速度;其中,所述纵向速度为与所述车辆行驶方向平行的方向的速度。采用本方法能够提高估计的车辆纵向速度的准确度。
