开发了一种由双转子电机和双排行星齿轮机构组成的机电无级传动混合动力驱动系统，建立了整车动力学模型，提出了“转矩分配+发动机转矩估计+电动机转矩补偿+补偿系数修正”的协调控制策略；最后分别对由纯电动模式切换到混合驱动模式的定工况和全工况进行仿真，结果表明：所提出的控制策略能有效地抑制驱动模式切换过程中因不同动力源动态特性差异所造成的整车纵向冲击，提高了汽车行驶平顺性。

An electro-mechanical variable transmission for hybrid power drive system is developed, which consists of a double-rotor motor and a two-row planetary gear set. Then a vehicle dynamics model is build and a co-ordinated control algorithm of “motor torque compensation and correction after torque pre-distribution and engine torque estimation” is proposed. Finally, simulations on the switching from pure electric mode to hybrid drive mode in two different conditions are performed. The results show that the proposed control strategy can effectively suppress the longitudinal jerk of vehicle caused by the discrepancy between dynamic characteristics of different power sources in the process of drive mode switching, and hence improve the ride comfort of vehicle.
