中文摘要：

针对一种采用行星齿轮机构的新型重度混合动力系统，为了缩短其开发周期，设计了该系统的硬件在环仿真试验平台，分析了该系统试验平台的总体结构和控制原理，制定了该混合动力系统在驱动工况和制动工况下台架试验控制流程。利用 MATLAB/Simulink 与 dSPACE 实时仿真平台开发了新型混合动力系统硬件在环试验控制系统，对系统的相关性能进行了试验验证。试验结果表明，所搭建的硬件在环试验系统能较好地验证新型混合动力系统的各种工作模式。

英文摘要：

A novel hybrid electric system was proposed based on planetary gears and the HIL bench of the system was designed.The whole structural and control principles of the bench were ana-lyzed.The control strategies of bench system were proposed based on driving and braking conditions. Finally,the HIL experimental bench of the novel hybrid electric system was developed by using tools based on MATLAB/Simulink and dSPACE real-time simulation platform and the performances of the system were verified.Test results show that different operating modes are achieved.
