The invention discloses a control method for an extended-range type hybrid power system of an electric drive axle semi-trailer tractor, and belongs to the field of hybrid power vehicle control. A traditional tractor is modified, the clutch, the gear mechanism, the motor and other components are additionally arranged, a transmission is omitted, and meanwhile a range extending system is formed; besides, a power battery and a driving motor are additionally arranged on the trailer, and a rear axle is integrated into a novel electric drive axle, so that a novel hybrid power system is constructed. For the hybrid power system, corresponding working modes and switching conditions of all the modes are provided, and the working modes mainly comprise a combined driving mode, a pure electric mode, a range extending mode, an engine direct driving mode, a parking charging mode, a regenerative braking mode and an engine starting mode. According to different modes, working states and control methods of corresponding parts are provided.
本发明公开了一种电驱桥半挂牵引车增程式混动系统的控制方法,属于混合动力车辆控制领域。本发明在传统牵引车的基础上进行改装,通过增加离合器、齿轮机构以及电机等部件,在取消了变速器的同时,形成了一种增程系统;此外,又在挂车上添加了动力电池和驱动电机,将后桥集成为一种新型的电驱桥,进而构造了一种新型的混合动力系统。针对该混合动力系统,又提出对应的工作模式以及各模式的切换条件,主要包括:联合驱动模式、纯电动模式、增程模式、发动机直驱模式、驻车充电模式、再生制动模式以及发动机启动模式。根据不同模式,提出了相应零部件的工作状态以及控制方法。
