The invention discloses an extended-range electric vehicle control method, a storage medium and a system, and the method comprises the steps: firstly obtaining the operation parameter data of an electric vehicle, including SOC, vehicle speed, vehicle demand power, driving motor rotating speed and driving motor peak torque; analyzing the required power of the target extended-range electric vehicle according to the opening degree of an accelerator pedal, the rotating speed of a driving motor and the peak torque of the driving motor; in order to ensure that the endurance mileage of a power battery of a target extended-range automobile in a CD mode is not shortened and the service life of the battery is not damaged due to too fast discharge, and meanwhile, the situation that the discharge power cannot meet the current power performance requirement when the electric quantity of the power battery is reduced is avoided. In the CDCS, increasing the endurance mileage of the target extended-range electric vehicle in the CD stage by adding a threshold value SOCe; the target working point of the target extended-range electric vehicle is adjusted according to the parameters such as the required power, the SOC and the vehicle speed, and the working state of the whole vehicle is adjusted according to the running state of the whole vehicle.

    本发明公开了一种增程式电动汽车控制方法、存储介质及系统,该方法首先获取电动汽车的运行参数数据,包括SOC、车速、整车需求功率、驱动电机转速和驱动电机峰值扭矩;然后根据油门踏板开度、驱动电机转速和驱动电机峰值扭矩,对目标增程式电动汽车的需求功率进行分析;为了确保目标增程式汽车在CD模式下的动力电池不会因为过快的放电导致续航里程缩短并损害电池寿命,同时也避免在动力电池电量下降时放电功率无法满足当前的动力性能要求。在CDCS中,通过增加一个阈值SOC_e来提高目标增程式电动车在CD阶段的续航里程;根据需求功率、SOC、车速等参数调整目标增程式电动汽车的目标工作点,实现了整车的运行状态来调整其工作状态。
