The invention discloses an electric vehicle power consumption calculation method, a vehicle control unit, an electric vehicle power consumption calculation system and an automobile. When the per-hundred-kilometer power consumption of an electric vehicle is calculated, the power consumption of the electric vehicle in each mileage interval section can be calculated according to the mileage data of the electric vehicle and the electric signal of a power battery in each mileage interval section only when the gear signal of the electric vehicle is a forward gear signal or a reverse gear signal (thevehicle is in a non-static state). The power consumption generated when the electric vehicle is in a static state is prevented from being classified into power consumption data generated when the electric vehicle runs; the mileage interval section can be divided into interval sections taking a hundred kilometer as a unit, so that the precision of a calculation result of per-hundred kilometer power consumption of the electric vehicle is improved; and the method has more representative significance for evaluating the running power consumption condition of the whole vehicle and estimating the remaining endurance mileage of the electric vehicle.
本发明公开了一种电动车电耗计算方法、整车控制器、电动车电耗计算系统及汽车。在计算电动车的百公里电耗时,只有在电动汽车的档位信号为前进档位信号或倒退档位信号时(汽车处于非静止状态),才根据电动汽车的行驶里程数据和每个里程区间段内的动力电池的电信号,计算电动汽车每个里程区间段内的电耗。避免了将电动汽车处于静止状态时的电耗归入到电动汽车行驶时的电耗数据中,对于里程区间段可以划分为以百公里为单位的区间段,提高了电动汽车百公里电耗的计算结果的精度,对于评估整车行驶耗电情况和预估电动汽车剩余续航里程更具有代表意义。
