混合动力驱动是提高车辆燃油经济性的重要措施。对一种新兴混合动力卡车进行了燃油经济性方面的仿真研究。该混合动力卡车由牵引车和带电驱动的挂车组成,牵引车和挂车之间通过内置测力传感器的牵引鞍座连接,通过分析该传感器信号来控制电动机在制动回收、空载以及动力辅助3种模式之间进行切换。基于IPG/Truck Maker和MATLAB/Simulink搭建了前向联合仿真模型并进行了仿真研究。仿真结果表明,该种混合动力方式可以明显改善挂车列车燃油经济性。
Hybrid drive is to improve vehicle fuel economy is an important measure. The fuel economy of an emerging hybrid truck was simulated. The hybrid truck consists of a tractor and an electrically driven trailer. The tractor and the trailer are connected to each other by a traction saddle with built-in load cells. The sensor signals are analyzed to control the motor during brake recovery, idling and power assist 3 Switch between modes. Based on IPG / Truck Maker and MATLAB / Simulink, the forward joint simulation model is built and simulated. The simulation results show that this kind of hybrid mode can obviously improve the fuel economy of the trailer train.
