The invention provides a vehicle hybrid mode control method based on a P2.5 + P4 hybrid configuration. The vehicle hybrid mode control method comprises the steps that vehicle control modes are divided into a pure electric rear-drive mode, a pure electric front-drive mode, a pure electric four-drive mode, a parallel four-drive mode, a parallel front-drive mode, a series rear-drive mode and an idling power generation mode; sOC intervals corresponding to a pure electric drive mode, a hybrid drive mode and an idle power generation mode are set, and torque intervals corresponding to rear drive and four-wheel drive are set; and the SOC and the demand torque of a vehicle power battery are obtained, and a vehicle control mode is selected according to the SOC and the demand torque. According to the invention, the conversion of the hybrid control mode of the hybrid vehicle can be adjusted more intelligently, the energy is saved to a greater extent, and the energy-saving property and intelligence of the vehicle are improved.

    本发明提供一种基于P2.5+P4混动构型车辆混动模式控制方法,包括:将车辆控制模式分为纯电后驱模式、纯电前驱模式、纯电四驱模式、并联四驱模式、并联前驱模式、串联后驱模式和怠速发电模式;设置纯电驱动模式、混合驱动模式和怠速发电模式时对应的SOC区间,及设置后驱驱动和四驱驱动所对应的扭矩区间;获取车辆动力电池的SOC和需求扭矩,并根据所述SOC和所述需求扭矩选择车辆控制模式。本发明能更加智能调节混动车辆的混动控制模式的变换,实现更大程度的能量节省,提高车辆的节能性和智能性。
