The invention discloses a whole vehicle mass estimation method and device.The method comprises the steps that the current driving state of a vehicle is recognized, and when the current driving state is an acceleration state, the first driving distance in the first stage, energy capable of being used for kinetic energy conversion in the first stage and the second stage and the kinetic energy variation of unit mass in the acceleration process are calculated; and calculating the driving distance of the second stage in the acceleration process, the energy capable of being used for kinetic energy conversion and the unit mass kinetic energy variation under the first driving distance, and the energy capable of being used for kinetic energy conversion and the unit mass kinetic energy variation under the second driving distance, and further estimating the whole vehicle mass of the vehicle. Therefore, the technical problems that in the prior art, due to the fact that the passing distances of the vehicles are different, it cannot be guaranteed that the energy consumption of the vehicles meets the calculation conditions when the whole vehicle mass estimation is calculated in an energy consumption mode, and the accurate whole vehicle estimated mass cannot be obtained in time are solved.

    本申请公开了一种整车质量估计方法及装置,其中,方法包括:识别车辆的当前行驶状态,并在当前行驶状态为加速状态时,计算加速过程中第一阶段的第一行驶距离、第一阶段和第二阶段的可用于动能转换的能量和单位质量的动能变化量,计算加速过程中第二阶段的行驶距离,第一行驶距离下的可用于动能转换的能量和单位质量动能变化量和第二行驶距离下的可用于动能转换的能量和单位质量动能变化量,进而估计车辆的整车质量。由此,解决了相关技术中由于车辆通过的距离并不相同,通过能耗的方式计算整车质量估计无法保证车辆的能耗满足计算条件,无法及时获得准确的整车估计质量的技术问题。
