The invention discloses a pure electric vehicle driving mileage display method and system, and the method comprises the steps: obtaining the SOC information of a vehicle, and determining the remaining driving standard announcement mileage through the NEDC working condition; acquiring the battery energy consumption of the driving mileage in the driving cycle period, and calculating the battery energy consumption of the average driving mileage per kilometer; obtaining battery residual energy, and calculating to obtain a dynamic mileage capable of remaining driving under the current working condition according to the battery energy consumption and the battery residual energy of the average driving mileage per kilometer; enabling the actual announcement mileage to approach the dynamic mileage to obtain the surface display mileage; and controlling an instrument to display the remaining driving mileage according to the meter display mileage information of the meter display mileage. The invention aims to provide a brand-new full electric vehicle driving range display method, focuses on user experience, and displays the remaining driving range data of the vehicle to the user as accurately as possible. Meanwhile, the announcement mileage is dynamically corrected, the current power consumption of the vehicle is monitored in real time in the calculation process, and necessary correction coefficients are introduced to avoid sudden change of the residual driving mileage displayed by the meter, so that the display result is more accurate on the premise that the real driving condition is represented as far as possible. And the remaining mileage data displayed by the meter can be changed smoothly when the vehicle runs.

    本发明公开了一种纯电动车续驶里程显示方法及系统,其中,方法包括获取车辆的SOC信息并通过NEDC工况,确定剩余续驶的标准公告里程;获取驾驶循环周期内行驶里程的电池能耗,计算平均每公里行驶里程的电池能耗;获取电池剩余能量,根据平均每公里行驶里程的电池能耗与电池剩余能量,计算得到当前工况下可剩余续驶的动态里程;使实际公告里程趋近动态里程,得到表显里程;根据所述表显里程的表显里程信息控制仪表显示剩余续驶里程。本发明旨在提供一种全新的纯电动车续驶里程显示方法,聚焦用户体验,尽可能较准确将车辆剩余续驶里程数据展示给用户。同时对公告里程进行动态修正,在计算过程中实时监测车辆当前的电耗,同时为避免表显剩余续驶里程发生突变,引入必要的修正系数,使显示结果在尽可能表征真实驾驶工况的前提下,又能在车辆行驶时让表显剩余里程数据平滑的进行变化。
