The invention relates to the technical field of vehicles, in particular to a vehicle speed correction method and device, a vehicle and a storage medium, and the method comprises the steps that the current vehicle speed of the vehicle and the actual tire pressure value of each tire are collected; the tire deformation radius of each tire is calculated according to the actual tire pressure value of each tire, and the average value of the tire deformation radiuses of all the tires is calculated; generating the tire rolling radius of the vehicle according to the sum of the average value and the tire standard rolling radius, and correcting the current vehicle speed according to the tire rolling radius to obtain the actual vehicle speed of the vehicle. Therefore, the problems that the influence of tire deformation on the tire rolling radius is not considered in the prior art, and errors exist in the vehicle speed calculated through the tire radius are solved, the errors of the vehicle speed calculated through the tire radius are made up, and therefore the more accurate vehicle speed is calculated.

    本申请涉及车辆技术领域,特别涉及一种车辆的车速修正方法、装置、车辆及存储介质,其中,方法包括:采集车辆的当前车速和每个轮胎的实际胎压值;根据每个轮胎的实际胎压值计算得到每个轮胎的轮胎变形半径,并计算所有轮胎的轮胎变形半径的平均值;根据平均值和轮胎标准滚动半径之和生成车辆的轮胎滚动半径,并根据轮胎滚动半径修正当前车速,得到车辆的实际车速。由此,解决了相关技术没有考虑到轮胎形变对于轮胎滚动半径的影响,通过轮胎半径计算的车速均存在误差的问题,弥补通过轮胎半径计算车速的误差,从而计算出更为精确的车速。
