The invention provides a vehicle speed estimation method and device, a storage medium and a vehicle, and the method comprises the steps: obtaining a slip estimation label corresponding to each wheel of the vehicle; determining an attachment state corresponding to the vehicle according to the slip estimation label; vehicle speed estimation is carried out according to the estimation mode matched with the attachment state corresponding to the vehicle, and the whole vehicle speed of the vehicle is obtained. According to the vehicle speed estimation method and device, the slip estimation label of each wheel is obtained, the attachment state of the vehicle is obtained based on the slip estimation label, the vehicle speed is estimated in the estimation mode matched with the attachment state to obtain the vehicle speed of the whole vehicle, and the vehicle speed can be estimated in different estimation modes under the condition that the vehicle is in different attachment states; the influence of wheel slip on the accuracy of the estimated whole vehicle speed is reduced, and the accuracy and reliability of the whole vehicle speed are improved.

    本发明提供一种车速估算方法、装置、存储介质及车辆,其中,车速估算方法包括:获取车辆的各车轮分别对应的打滑预估标签;根据所述打滑预估标签,确定所述车辆对应的附着状态;根据与所述车辆对应的附着状态匹配的估算方式进行车速估算,得到所述车辆的整车车速。本发明通过获取每一车轮的打滑预估标签,基于打滑预估标签得到车辆的附着状态,并通过与附着状态匹配的估算方式进行车速估算得到整车车速,可以在车辆处于不同的附着状态的情况下,采用不同的估算方式进行车速估算,降低了车轮打滑对估算得到的整车车速准确性的影响,提高了整车车速的准确性和可靠性。
