The invention provides a commercial vehicle load state estimation method and device and a storage medium, and the method comprises the steps: carrying out the load estimation after a vehicle machine system of a commercial vehicle is powered on, and obtaining a plurality of current load estimation values; if a first group of historical load estimation values exist in a first historical operation period and the load state of the first historical operation period is unknown, calculating a size relationship between the current load estimation value and a statistical characteristic value of the first group of historical load estimation values; if the current load estimation value is greater than the statistical characteristic value and meets a preset threshold condition, determining that the current load state is full load and the load state of the first historical operation period is no load; and if the current load estimation value is smaller than the statistical characteristic value and meets a preset threshold condition, determining that the current load state is no-load and the load state of the first historical operation period is full-load so as to accurately estimate the load state of the commercial vehicle.
本申请提供一种商用车载重状态的估计方法、设备和存储介质,方法包括:在商用车的车机系统上电后间隔设定时长进行载重估计,得到多个当前载重估值;如果存在第一历史运行周期内的第一组历史载重估值且所述第一历史运行周期的载重状态未知,计算所述当前载重估值与所述第一组历史载重估值的统计特征值的大小关系;如果所述当前载重估值比所述统计特征值大且满足预设的阈值条件,确定当前载重状态为满载,所述第一历史运行周期的载重状态为空载;如果所述当前载重估值比所述统计特征值小且满足预设的阈值条件,确定当前载重状态为空载,所述第一历史运行周期的载重状态为满载,以准确评估商用车载重状态。
