The invention discloses a plateau power guarantee control method, system and device for a hybrid electric vehicle and a storage medium. The method comprises the following steps: when an EV/HEV mode is normally operated, calculating the altitude at which a vehicle runs according to the environment temperature and the atmospheric pressure; judging whether the altitude height reaches a preset height or not; and if the preset height is reached, correcting the engine target rotating speed, the sliding power generation power, the accelerator stepping power generation power, the battery power limitation and the plateau region power generation torque line lifting according to the atmospheric pressure corresponding to the altitude. According to the technical content disclosed by the invention, the power guarantee of the whole vehicle is corrected according to different altitudes, so that the electric quantity of the whole vehicle in accordance with the altitude environment is reasonably output; by adding the logic, the electric quantity of the hybrid electric vehicle in different altitude areas can be flexibly and accurately controlled so as to meet the requirements of dynamic property and driving comfort in different areas.

    本发明公开了一种混动汽车高原保电控制方法、系统、设备及存储介质。其中,方法包括:当EV/HEV模式正常运行,根据环境温度和大气压力计算车辆行驶的海拔高度;判断所述海拔高度是否达到预设高度;如果达到所述预设高度,根据海拔对应的大气压修正发动机目标转速、滑行发电功率、踩油门发电功率、电池功率限制和高原地区发电扭矩线提升。本发明公开的技术内容,实现根据不同的海拔时对整车保电进行修正,从而合理地输出符合该海拔环境下的整车电量,通过增加该逻辑可以灵活并精确的控制混动车在不同海拔地区的电量以达到满足不同地区的动力性和驾乘舒适性要求。
