Abstract: The ambient temperature has a great impact on the true driving range of pure electric vehicles. Therefore, this paper designs a new instrument display strategy of driving range based on the instrument display function of pure electric vehicles and taking the environmental temperature factor into consideration.This strategy effectively reduces the deviation between the vehicle's driving mileage displayed by the instrument under different ambient temperatures and the vehicle's real driving mileage, so that users can more accurately evaluate the vehicle's real driving mileage while using the vehicle, and thus improve the user's car experience.

Key words: Pure electric cars; Show continued mileage; True continuous mileage; Environment temperature

摘要： 环境温度对于纯电动汽车的真实续驶里程有极大的影响，因此，文章针对纯电动汽车的仪表显示续驶里程功能，将环境温度因素考虑在内，设计了一种新的仪表显示续驶里程策略。该策略有效降低了车辆在不同环境温度 下仪表显示续驶里程与车辆真实续驶里程之间的偏差，使用户在用车时能够更加准确地评估车辆的真实续驶里程， 提升了用户的用车体验。
