为研究综合传动车辆的动态性能,以综合传动的组成和工作原理为基础,分析了换挡过程,建立了整车系统的动力学模型和各组成部分的数学模型,采用模块化的建模方法和图形化建模工具,建立了系统的仿真模型。基于模糊控制理论,建立了车辆行驶过程的模糊换挡控制系统。并对直驶起步加速换挡工况进行了仿真。仿真结果能够较好地描述车辆的动态性能,表明了所建立的仿真模型和模糊换挡控制规律的正确性和有效性,从而为车辆的设计和性能预测奠定了基础。
In order to study the dynamic performance of the integrated transmission vehicle, based on the composition and working principle of the integrated transmission, the shift process was analyzed and the dynamic model of the whole vehicle system and the mathematical model of each component were established. The modular modeling method And graphical modeling tools, the establishment of a system simulation model. Based on the fuzzy control theory, the fuzzy shift control system of vehicle driving process is established. And the simulation of the starting gearbox acceleration and shifting conditions. The simulation results can describe the dynamic performance of the vehicle well, and demonstrate the correctness and validity of the established simulation model and the fuzzy shift control law, which lays the foundation for the design and performance prediction of the vehicle.
