摘　　要：通过对混合动力汽车电无级变速器传动机构原理分析,提出一种内燃机最佳效率控制策略。该策略主要是基于底层控制系统的硬件结构,根据上位机发送的指令对双机械端口电机的内转子进行转矩控制,实现内燃机最佳效率运行;对外转子进行转速控制,满足车辆运行需求。并且给出了该策略下转矩辨识的方法;同时给出在整车中车辆总成控制与双机械端口电机控制系统和其他系统配合关系。通过实验,验证了该控制策略可以实现内燃机最佳效率运行同时满足负载侧连续平滑调速的可行性。By analyzing the basic working principle,an internal combustion engine（ICE） optimal efficiency control strategy of electrical variable transmission in hybrid electrical vehicle which mainly concerns the inner rotor torque control to and outer rotor speed control to satisfy the efficiency and load demands based on the low level control systems by following the commands of the host computer is given in this paper.The torque identification method is discussed and given in this paper.Furthermore,the corporation relationship of the lower level control systems and the host computer of the vehicle is discussed in the paper.By experiment,the feasibility of the control system and its control strategy is tested and verified.
