The invention relates to a vehicle load adaptive estimation method and device and a storage medium, and relates to the technical field of load estimation. The method comprises the steps of building a load estimation model and setting load estimation triggering conditions. In the vehicle running process, the load estimation model is loaded, the initialized load estimation model gives an initial load, and the output load is equal to the initial load; if the whole vehicle state triggers the set load estimation triggering condition in the vehicle running process, acceleration data are collected and recorded, the acceleration data are processed through moving average in a fixed interval to obtain an average acceleration, a load mode is recognized according to an acceleration fluctuation interval where the average acceleration is located, and a load estimation value is determined according to the load mode; the output load is equal to the load estimate. The method does not depend on a mechanical theoretical model and the calculation precision of the road gradient, the whole vehicle load of the AMT light truck can be conveniently, rapidly and adaptively estimated under different load working conditions, and the calculation complexity can be reduced.

    本发明涉及一种车辆载荷自适应估算方法、装置及存储介质,涉及载荷估算技术领域。本发明包括搭建载荷估算模型,设定载荷估算触发条件。在车辆运行过程中,加载载荷估算模型,初始化的载荷估算模型给出初始载荷,输出载荷等于初始载荷;若车辆运行过程中,整车状态触发设定的所述载荷估算触发条件,则采集记录加速度数据,通过固定区间的滑动平均处理加速度数据得到平均加速度,根据平均加速度所处的加速度波动区间识别载荷模式,根据载荷模式确定载荷估算值,输出载荷等于载荷估计值。本申请不依赖力学理论模型,不依赖道路坡度的计算精度,在不同的载荷工况下,能够方便快捷地自适应地估算出AMT轻卡的整车载荷,能够降低计算复杂度。
