The invention discloses a longitudinal speed estimation method and device of a vehicle and electronic equipment, and relates to the technical field of vehicle control. The method comprises the steps of obtaining at least one slip flag bit of a vehicle, determining a slip state corresponding to the vehicle based on a parameter corresponding to the at least one slip flag bit, and determining a speed estimation method corresponding to the slip state based on a corresponding relation between a preset slip state and a preset speed estimation method, and the longitudinal speed of the vehicle is calculated based on a speed estimation method. According to the method, corresponding estimation methods are adopted for different slip states, the longitudinal speed is obtained, and the estimation accuracy of the longitudinal speed of the vehicle is effectively improved.

    本申请公开了一种车辆的纵向速度估算方法、装置以及电子设备,涉及车辆控制技术领域。本申请的方法包括:获取车辆的至少一个滑移标志位,基于至少一个滑移标志位对应的参数,确定出车辆对应的滑移状态,基于预设滑移状态与预设速度估算方法之间的对应关系,确定出滑移状态对应的速度估算方法,并基于速度估算方法计算出车辆的纵向速度。通过上述的方法,针对不同的滑移状态采用相应的估算方法,获取纵向速度,有效的提高了车辆纵向速度的估算准确性。
