研究了双模式功率分流型混合动力汽车的模式转换特性，提出了一种减小模式转换过程中驱动轴转矩变化的控制算法。为了分析双模功率分流变速器在模式切换过程中的特性，建立了行星齿轮、发动机、电动发电机、电池和车辆的动力学模型，并开发了双模功率分流变速器混合动力汽车性能模拟器。利用该仿真器，研究了模式转换过程中的瞬态特性，并提出了一种通过电机转矩补偿来减小转矩波动的控制方法。在模式改变期间，根据惯性转矩计算电机转矩的大小。实验结果表明，所提出的控制算法可以有效地减小转矩波动。
In this study, the mode change characteristics of the dual mode power split type hybrid electric vehicle were investigated, and a control algorithm was proposed to reduce the torque variation of the drive shaft during the mode change. To analyze the characteristics of the dual mode power split transmission during mode change, dynamic models for the planetary gear, engine, motor-generator, battery and vehicle were established, and a performance simulator for the dual mode power split transmission hybrid electric vehicle was developed. Using the simulator, a transient characteristics during the mode change were investigated and a control method was proposed to reduce the torque variation the motor torque compensation. The magnitude of the motor torque was calculated from the inertia torque during the mode change. It was found that the torque variation can be effectively reduced by the proposed control algorithm.
