The invention discloses a hybrid electric vehicle power mode switching control method, and belongs to the technical field of hybrid electric vehicles, the hybrid electric vehicle power mode switching control method comprises a pure electric EV driving mode, a forced pure electric MEX-EV driving mode, an HEV intelligent electricity reporting mode and an HEV forced electricity protection mode, the pure electric EV driving mode is a conventional power battery electric driving mode, and when a high-power demand exists, the pure electric MEX-EV driving mode is a normal power battery electric driving mode. A fuel oil mode is adopted for power generation, a forced pure electric MEX-EV driving mode is adopted, in most cases, only a power battery is used for electric driving, and when the electric quantity is low enough, the mode is quitted, and the fuel oil mode is switched. On the REEV/PHEV hybrid power vehicle model, according to different vehicle models and different interaction requirements, the driving mode, the driving mode, the energy recovery level, the power protection mode, the SOC balance point and the like of the hybrid power system are adjusted and set. A power mode switching strategy comprises four different modes: a pure electric EV driving mode, a forced pure electric MEX-EV driving mode, an HEV intelligent power protection mode and an HEV forced power protection mode.

    本发明公开了一种混合动力汽车动力模式转换控制方法,属于混合动力汽车技术领域,包括纯电EV驱动模式、强制纯电MEX‑EV驱动模式、HEV智能报电模式和HEV强制保电模式,纯电EV驱动模式为常规的动力电池电驱动方式,在有大功率需求时,采用燃油方式进行发电,强制纯电MEX‑EV驱动模式,其在多数情况下,仅适用动力电池电驱动,当电量足够低的时候,会退出此模式,切换为燃油模式。本发明在REEV/PHEV的混动车型上,针对不同车型、不同的交互需求,对混动系统的驱动模式、驾驶模式、能量回收等级、保电模式、SOC平衡点等进行调节设定。其动力模式切换策略包含四种不同的模式:纯电EV驱动模式、强制纯电MEX‑EV驱动模式、HEV智能保电模式、HEV强制保电模式。
