The invention relates to a pure electric vehicle energy consumption monitoring optimization method, which comprises the steps of setting a target place where a vehicle needs to arrive, and starting tocollect vehicle operation information after the vehicle is started; determining an actual road condition from the target location to the location of the current vehicle, and simulating the actual road condition information; when the driving cycle number i is larger than or equal to 1, starting energy consumption evaluation; calculating and obtaining real-time energy consumption efficiency in thecurrent energy consumption evaluation period, and displaying the real-time energy consumption efficiency Ei and the energy consumption rate Ei-1 in the (i-1) th energy consumption evaluation period ona vehicle-mounted instrument; giving an optimization suggestion of the driving behavior; and through comparing the residual electric quantity of the battery with the residual demand electric quantity, giving a prompt of whether the driver can normally arrive at the target place. The invention further discloses a pure electric vehicle energy consumption monitoring and optimizing system. The current energy consumption condition can be accurately provided for the driver, suggestions can also be provided for the driving behavior of the driver, and energy conservation and consumption reduction ofthe whole vehicle are achieved.

    本发明涉及一种纯电动汽车能耗监测优化方法,包括:设置车辆需要抵达的目标地点,车辆启动后,开始采集车辆运行信息;确定目标地点到当前车辆所在位置的实际路况,对实际路况信息进行模拟;当行驶周期数i≥1时开始进行能耗评估;在当前能耗评估周期内计算获取实时能量消耗效率,将实时能量消耗效率E和第i‑1个能耗评估周期下的能量消耗率E显示在车载仪表上;给出驾驶行为的优化建议;通过电池的剩余电量和剩余需求电量对比,给出驾驶员能否正常抵达目标地点的提示。本发明还公开了一种纯电动汽车能耗监测优化系统。本发明不仅能够较为准确向驾驶员提供目前的能量消耗情况,也能给驾驶员的驾驶行为提供建议,实现整车节能降耗。
