The invention provides a vehicle speed estimation method and device and a vehicle, and the method relates to the field of vehicles, and comprises the steps: obtaining the wheel center speed of each wheel in the vehicle, the longitudinal acceleration of the vehicle and the driving state information of the vehicle; wherein the driving state information is used for representing whether the vehicle is in a slip state; obtaining an initial longitudinal speed of the vehicle based on the longitudinal acceleration; determining a first weight coefficient of each wheel and a second weight coefficient of the vehicle based on the driving state information; and determining a target longitudinal speed of the vehicle based on the wheel center speed, the first weight coefficient, the initial longitudinal speed and the second weight coefficient. According to the method, the accuracy of the estimated longitudinal vehicle speed can be improved, so that the safety of the vehicle is improved.

    本申请提供了一种车速的估算方法、估算装置及车辆,该方法涉及车辆领域,包括:获取车辆中各车轮的轮心速度、车辆的纵向加速度与车辆的行驶状态信息;其中,行驶状态信息用于表示车辆是否处于滑移状态;基于纵向加速度,得到车辆的初始纵向车速;基于行驶状态信息,确定各车轮的第一权重系数与车辆的第二权重系数;基于轮心速度、第一权重系数、初始纵向车速与第二权重系数,确定车辆的目标纵向车速。该方法能够提高估算的纵向车速的准确性,从而提高车辆的安全性。
