The invention relates to the technical field of new energy vehicles, in particular to a vehicle endurance mileage self-adaptive estimation method and device, a vehicle and a storage medium, and the method comprises the following steps: after a whole vehicle is powered on, obtaining voltage and current data fed back by a battery management system every first preset time, and obtaining power consumption data information based on the voltage and current data; acquiring a mileage data value of vehicle driving every second preset time, and acquiring a process time consumption data value when the mileage data value is increased by a preset interval mileage value every time; determining a unit power consumption value based on the power consumption data information and the time consumption data value; repeating the previous steps to obtain a power consumption data set comprising a plurality of unit power consumption values; performing primary power consumption correction based on the power consumption data set to obtain a dynamic power consumption value; secondary power consumption correction is carried out based on the dynamic power consumption value and the set propaganda power consumption, the endurance mileage data to be fed back are obtained, the difference between the displayed endurance mileage and the actual endurance mileage is reduced, and meanwhile the method is wider in application scene.
本申请涉及新能源车辆技术领域,尤其是涉及一种车辆续航里程自适应预估方法、装置、车辆及存储介质,方法包括整车上电后,每隔第一预设时间获取电池管理系统反馈的电压及电流数据,基于电压及电流数据以得到电耗数据信息;每隔第二预设时间获取车辆行驶的里程数据值,并且当里程数据值每增加预设的间隔里程值,获取该过程耗时数据值;基于电耗数据信息及耗时数据值,确定单位电耗值;重复前述步骤以得到包括多个单位电耗值的电耗数据集;基于电耗数据集,进行一次电耗修正,得到动态电耗值;基于动态电耗值及设定的宣传电耗,进行二次电耗修正,得到待反馈的续航里程数据,方法减小显示续航里程与实际的续航里程差距,同时方法适用场景更广。
