The invention relates to a multi-mode hybrid power system with input and output power dividing and parallel connection modes, which comprises a planetary gear mechanism, two clutches and a synchronizer. And four hybrid power driving modes, namely a parallel mode (single-torque decoupling and double-torque decoupling), an input power shunting mode (rotating speed-torque decoupling) and an output power shunting mode (torque-rotating speed decoupling), are realized. The system comprises a first power source (engine), a second power source (motor), a third power source (motor) and related transmission mechanisms. Through switching of different modes, the system can adapt to various working conditions, and good energy consumption economy is provided. In addition, the system is simple in structure, easy to control, high in transmission efficiency and suitable for spatial arrangement, supports multiple working modes such as pure engine driving, pure electric driving, regenerative braking and parking charging, and improves the performance of the vehicle in the whole working condition domain.

    本发明涉及一种具有输入输出功率分流与并联模式的多模混合动力系统,通过行星齿轮机构、两个离合器和一个同步器,实现四种混合动力驱动模式:并联模式(单转矩解耦、双转矩解耦)、输入功率分流模式(转速‑转矩解耦)和输出功率分流模式(转矩‑转速解耦)。该系统包括第一动力源(发动机)、第二动力源(电动机)、第三动力源(电动机)及相关传动机构。通过不同模式的切换,系统可适应各种工况,提供良好的能耗经济性。此外,该系统结构简单、控制容易,传动效率高,适合空间布置,支持多种工作模式如纯发动机驱动、纯电驱动、再生制动、驻车充电等,提升车辆在全工况域内的表现。
