The invention belongs to the field of electric vehicle control, and discloses a control method and system for calculating the remaining driving range of a pure electric vehicle, and the method comprises the steps: obtaining the real-time battery power consumption and the driving distance of the pure electric vehicle in a driving state; the calculation result of the remaining driving mileage of the pure electric vehicle is controlled, and the remaining driving mileage of the electric vehicle is estimated based on the current battery power consumption and the driving distance with a fixed unit time as a period; and when the estimated residual driving mileage is lower than the residual driving mileage of the previous period, adopting the estimated residual driving mileage. The method can help to reduce the deviation between the remaining driving mileage and the actual driving mileage of the electric vehicle, and reduce the dissatisfaction of users.

    本发明属于电动汽车控制领域,公开了一种计算纯电动汽车剩余续驶里程的控制方法及系统,包括获取纯电动汽车行驶状态中的实时电池耗电量及行驶距离;控制纯电动汽车剩余续驶里程的计算结果,以固定的单位时间为周期,基于当前电池耗电量及行驶距离估算电动汽车的剩余续驶里程;当估算的剩余续驶里程低于前一周期的剩余续驶里程,则采用估算的剩余续驶里程。该方法可以帮助减少电动汽车剩余行驶里程与实际可行驶里程之间的偏差,减少用户因其的不满。
