The invention relates to the technical field of electric vehicles, in particular to an extended-range electric vehicle endurance mileage algorithm, which comprises the following steps of: S1, aiming at different batteries, obtaining real-time available residual electric quantity Ebatteriaval of the batteries; the method comprises the following steps: S1, starting a VCU (vehicle control unit), S2, after the VCU is initialized, reading data of a previous driving cycle in an EEPROM (electrically erasable programmable read-only memory), and calculating average power consumption data per hundred kilometers and pure electric endurance mileage, S3, carrying out upper and lower limit value processing on the filtered pure electric endurance mileage, S4, calculating oil-electricity comprehensive endurance mileage, S5, carrying out limit value processing on the oil-electricity comprehensive endurance mileage again, and S5, carrying out limit value processing on the oil-electricity comprehensive endurance mileage. The problem that the driving mileage is calculated inaccurately at the present stage, if a driver does not supplement energy in time when a charging pile is far away from a gas station, the vehicle may lie down due to no oil and no electricity, and normal vehicle use of a user is affected is solved.

    本发明涉及电动汽车技术领域,具体地说,本发明涉及一种增程式电动汽车续航里程算法,包括以下步骤:步骤S1,针对不同电池,得到电池的实时可用剩余电量Ebatteryaval;步骤S2,整车上电VCU初始化后,读取EEPROM中的上个驾驶循环的数据,并计算平均百公里电耗数据以及纯电续航里程,步骤S3,对滤波后的纯电续航里程进行上下限值处理,步骤S4,计算油电综合续航里程,步骤S5,对油电综合续航里程再次进行限值处理,解决了现阶段续航里程由于计算不准确,在充电桩和加油站相距较远时,如果驾驶员未及时补能,那么可能发生车辆无油无电造成车辆趴窝,影响用户正常用车的问题。
