混联式混合动力汽车采用行星轮系将一台内燃机和两台电动机联合收割机组合起来，通过控制功率流，可以充分发挥混联式和串联式混合动力系统的优点。在该系统中，功率流的控制不仅意味着调整机械和电力的量和方向，而且还意味着调整发动机的工作点。本研究介绍的功率分配策略，使用控制地图，以最大限度地减少功率流的损失，并运行在有效点的发动机。在给定速度、负载和蓄电池充放电功率的条件下，通过优化过程寻找有效工作点，得到控制图。所提出的策略有效地分配了功率流，并且由于电池功率可以容易地控制，因此有助于建立能量控制策略。
The series-parallel hybrid electric vehicle, which employs a planetary gear set to combine one internal combustion engine and two electric motors, can take advantages of both series and parallel hybrid system by controlling power flows. In this system, the control of power flows means adjusting not only the amount and direction of mechanical and electrical power but also the operating point of the engine. This study introduces the power distribution strategy which uses control maps to minimize the loss in power flow and operate engine on efficient point. And the control maps can be obtained by optimization process seeking efficient operating point for the given speed, load and battery charge/discharge power. The suggested strategy distributes the power flows efficiently and further, it helps to build energy control strategy since battery power can be controlled easily.
