The invention relates to a whole vehicle mass estimation method and device, a vehicle and a storage medium, and relates to the technical field of computers. The method comprises the steps that under the condition that a vehicle meets the vehicle mass updating condition, first vehicle mass is periodically determined based on longitudinal force, the first vehicle mass of M cycles is obtained, the longitudinal force is determined based on wheel end driving force, running resistance, driving wheel accelerating force and a wheel sliding correction coefficient, and the first vehicle mass of M cycles is obtained; and performing fitting processing on the first whole vehicle mass of the M periods to obtain second whole vehicle mass of the M periods, so that when the residual sum of squares of the first whole vehicle mass and the second whole vehicle mass of each period is smaller than a first preset threshold value, on the basis of the second whole vehicle mass of the M periods, a whole vehicle mass estimation value of each period is sequentially determined. Therefore, the whole vehicle mass estimation value can be determined according to the running resistance of the vehicle and the wheel sliding correction coefficient, and the accuracy of the whole vehicle mass estimation value is improved.
本申请涉及一种整车质量估算方法、装置、车辆及存储介质,涉及计算机技术领域。该方法包括:在车辆满足整车质量更新条件的情况下,基于纵向力周期性的确定第一整车质量,得到M个周期的第一整车质量,纵向力基于轮端驱动力、行驶阻力、驱动轮加速力以及车轮滑动修正系数确定,并对M个周期的第一整车质量进行拟合处理,得到M个周期的第二整车质量,从而在每个周期的第一整车质量和第二整车质量的残差平方和小于第一预设阈值时,基于M个周期的第二整车质量,依次确定每个周期的整车质量估算值。由此,可以根据车辆的行驶阻力和车轮滑动修正系数,确定整车质量估算值,提高整车质量估算值的准确度。
