The embodiment of the invention discloses a hybrid power system switch valve control method and device, an electric vehicle and a storage medium. The method comprises the steps that a real-time mode signal, main oil pressure and gear rotating speed of a vehicle are obtained; controlling the state of a switch valve in a hybrid power system of the vehicle according to the mode signal, the main oil pressure and the gear rotating speed of the vehicle; and the state of a high-low pressure decoupling valve of the hybrid power system is switched according to the state of the switching valve, so that an electronic pump in the hybrid power system is switched on a high-low pressure loop along with switching of the state of the high-low pressure decoupling valve. According to the embodiment of the invention, the state of the switching valve in the hybrid power system of the vehicle can be controlled from multiple dimensions, the vehicle demand can be responded in time, and the energy consumption of the vehicle is reduced.

    本申请的实施例揭示了一种混动系统开关阀控制方法、装置、电动车及存储介质。该方法包括:获取车辆实时的模式信号、主油压以及齿轮转速;根据所述车辆的模式信号、主油压以及齿轮转速控制所述车辆的混动系统中的开关阀的状态;根据所述开关阀的状态切换所述混动系统的高低压解耦阀的状态,以使所述混动系统中的电子泵在高低压回路上随着高低压解耦阀的状态的切换而切换。本申请的实施例能够不仅从多个维度控制车辆混合动力系统中开关阀的状态,还保证了及时响应车辆需求,减少了车辆的能耗。
