摘　　要：针对目前混联式驱动系统中机-电耦合动力传动装置结构复杂的问题,提出了一种两轴实时混联驱动系统,通过控制前机械桥离合器和后电动轮离合器,快速实现串、并联的不同组合,并可随时根据整车工作状态的需要在串、并联模式间任意切换。文中详细阐述了该驱动系统的结构和控制策略,并分析了其优缺点。In view of the complicated structure of electromechanical coupling power transmission device in existing parallel-series hybrid driving systems, a two-axle real-time parallel-series hybrid driving system is proposed. By controlling the engine clutch in front axle and the clutches for wheel hub motors in rear axle, the different combi- nation of series and parallel drive can be quickly realized, and the switching between parallel and series modes can be achieved whenever vehicle working conditions require. An elaboration is made upon the structure and control strategy of the new driving system with its advantage and deficiencies also analyzed in the paper.
