The invention relates to a new energy vehicle remaining endurance mileage calculation method and system and a medium. U1, a vehicle runs on a road, an associated state vector of the vehicle is collected in real time, and variable quantity data information of the associated state vector of the vehicle is obtained within specified time; and U2, based on the variable quantity data information of the associated state vector of the vehicle, a preset threshold value is set, if the variable quantity of the associated state vector of the vehicle is smaller than the preset threshold value, the vehicle runs in a relatively stable road condition, a calculation function L of the remaining endurance mileage is constructed, the remaining endurance mileage of the vehicle is calculated, and the remaining endurance mileage of the vehicle is calculated. And the remaining endurance mileage data information of the vehicle under the stable road condition is obtained. According to the method, a specific working condition matching rule is provided, the calculation accuracy of the remaining electric quantity mileage is improved, the judgment condition of the vehicle under the stable working condition is provided, a calculation method under the stable driving working condition is introduced, and the calculation cost is reduced.
本发明涉及一种新能源车辆剩余续航里程计算方法、系统及介质,U1.车辆行驶在道路上,实时采集车辆的关联状态向量,并在指定时间内获取车辆的关联状态向量的变化量数据信息;U2.基于所述车辆的关联状态向量的变化量数据信息,设置预设阈值,若车辆的关联状态向量的变化量小于预设阈值则车辆行驶在相对稳定的路况,构建剩余续航里程的计算函数L,对车辆的剩余续航里程进行推算,得到稳定路况下的车辆的剩余续航里程数据信息。本发明不仅提出具体的工况匹配规则,提高了剩余电量里程计算的精确度,而且提出车辆在稳定工况下的判断条件,引入稳定行驶工况下的计算方法,降低了计算成本。
