The invention relates to the technical field of power system control, in particular to a control method and device for idle speed power generation of a hybrid electric vehicle and a storage medium. The method comprises the steps that vehicle speed information and crawling driving wheel end torque information are obtained, and whether the vehicle is in an idle speed working condition or not is judged based on preset idle speed threshold value information; controlling the engine to enter a first operation mode and controlling the generator to enter a second operation mode; characterization information influencing the charging power is obtained, whether the vehicle is in a high-load power generation working condition or not is judged based on preset condition information, the power generation power of an engine and the power assembly state are obtained, and the power generation power of the engine is limited; based on the limited generated power, the target power generation torque of the engine and the target power generation rotating speed of the generator are obtained; and controlling the engine to execute the target power generation torque. Power generation can be performed when the generator enters the idling working condition, the idling power generation working range is expanded, electric energy is stored for an unknown stroke in advance, and the driving and high-load power requirements of a driver are considered.

    本发明涉及动力系统控制技术领域,具体涉及一种混动汽车怠速发电的控制方法、装置及储存介质,方法包括:获取车速信息和蠕行驱动轮端扭矩信息,基于预设的怠速阈值信息,判断车辆是否处于怠速工况;控制发动机进入第一运行模式,控制发电机进入第二运行模式;获取影响充电功率的表征信息,基于预设的条件信息判断车辆是否处于高负载发电工况,获取发动机的发电功率和动力总成状态,对发动机的发电功率进行限制;基于限制后的发电功率,获取发动机的目标发电扭矩和发电机的目标发电转速;控制发动机执行目标发电扭矩。本发明发电机进入怠速工况即可功率发电,拓展怠速发电工作范围,提前为未知行程储备电能,且兼顾驾驶员的驱动和高负载功率需求。
