The invention relates to the technical field of new energy vehicles, and discloses a control method and system for increasing the pure electric endurance mileage of an extended-range electric vehicle, and the method comprises the steps that a control module reads the vehicle environment temperature through a temperature sensor; when the vehicle environment temperature is greater than the preset temperature, the control module controls the start and stop of the range extender according to a first preset SOC value range; when the vehicle environment temperature is smaller than or equal to the preset temperature, the control module controls start and stop of the range extender according to a second preset SOC value range; the minimum value of the second preset SOC value range is greater than the minimum value of the first preset SOC value range, and the maximum value of the second preset SOC value range is greater than the maximum value of the first preset SOC value range. The preset SOC value range of starting and stopping of the range extender is dynamically designed according to the environment temperature of the vehicle, the pure electric endurance mileage of the vehicle at the normal temperature and the high temperature is increased, and the problem that the power performance of the vehicle at the low temperature is insufficient or the range extender is difficult to start is solved.

    本发明涉及新能源汽车技术领域,公开了一种提升增程式电动汽车纯电续航里程的控制方法及系统,该方法包括:控制模块通过温度传感器读取车辆环境温度;当车辆环境温度大于预设温度时,控制模块根据第一预设SOC值范围控制增程器的启停;当车辆环境温度小于等于预设温度时,控制模块根据第二预设SOC值范围控制增程器的启停;第二预设SOC值范围的最小值大于第一预设SOC值范围的最小值,第二预设SOC值范围的最大值大于第一预设SOC值范围的最大值。通过根据车辆环境温度动态地设计增程器的启动和停机的预设SOC值范围,增加了车辆常温和高温下的纯电续航里程,避免了低温下的车辆动力性能不足或增程器启动困难的问题。
