The invention belongs to the field of new energy automobiles and provides a new energy automobile driving endurance mileage prediction method and system, a medium and equipment. The method comprises steps that according to the real-time vehicle speed of vehicle driving, mileage values of vehicle driving in preset different time units are calculated, and then through recursive median average filtering processing, a mileage minimum unit of vehicle power consumption is obtained; an electric quantity value consumed in a preset time unit is calculated according to an instantaneous current value uploaded by a battery management system in real time, and recursive median average filtering processing is carried out to obtain an electric quantity minimum unit of power consumption of the whole vehicle; time shafts of the mileage minimum unit and the electric quantity minimum unit are synchronized, the mileage minimum unit and the electric quantity minimum unit of the whole vehicle power consumption are accumulated in the vehicle driving process, and when the driving mileage is accumulated to 1 km, accumulated electric quantity data locking is triggered; and the endurance mileage of the vehicle is locked based on the residual electric quantity and the electric quantity data locked each time when the electric quantity data is locked each time in the running process of the vehicle.

    本发明属于新能源汽车领域,提供了一种新能源汽车行车续航里程预测方法、系统、介质及设备。其中,该方法包括根据车辆行驶的实时车速,计算预设的不同时间单元内整车行驶的里程数值,再经递推中位值平均滤波处理,得到整车电耗的里程最小单元;根据电池管理系统实时上传的瞬时电流值,计算预设时间单元内消耗的电量数值,再经递推中位值平均滤波处理,得到整车电耗的电量最小单元;同步里程最小单元和电量最小单元的时间轴,在车辆行驶过程中分别累加整车电耗的里程最小单元及电量最小单元,当行驶里程累加到1km时,触发累加的电量数据锁定;在车辆行驶过程中在每次电量数据锁定时,基于剩余电量及每次锁定电量数据来更新车辆续航里程。
