【摘要】：随着技术的发展、人们对能源和环保的重视,无级变速器(CVT)在现代汽车产业得到了越来越多的应用。传统的CVT由于其液压系统的低效率和高故障率,使其得不到推广使用。而本文研究的纯机械电子式无级变速器EMCVT (Electronic Mechanical Continuously Variable Transmission)则是利用EMCVT的控制系统对离合器电机和速比电机的控制来实现对夹紧力和传动比的控制。 EMCVT控制系统开发调试过程,是把EMCVT先后安装到试验台架和汽车上进行实验调试,但台架试验和车载试验的试验周期长、设备多、体积大、不便于移动、成本很高、而且极端情况安全性不足。所以本文利用硬件在环仿真(Hardware-in-the-loop Simulation-HILS)技术对试验台架进行仿真,搭建便携式硬件在环仿真试验平台(HILSP),为EMCVT控制系统在开发初期提供了虚拟调试环境,以缩短开发周期、降低开发成本。本文首先对仿真对象EMCVT.现场试验台架、EMCVT控制系统作了详细的分析,根据发动机的试验数据利用Matlab/Simulink建立了发动机模型,利用试验台架的机械结构建立起了离合器模型、EMCVT模型、汽车负载模型,并且建立了基于LabVIEW的各个仿真模型。其次本文开发了该硬件在环仿真平台的数据采集模块,编写了基于LabVIEW的硬件在环仿真平台软件系统,实现了仿真模型与EMCVT控制系统之间的实时数据通讯和对控制系统的调试功能,为其提供了在实验室完成虚拟台架试验的环境。本文最终搭建起了一个便携式EMCVT硬件在环仿真平台,作为EMCVT控制系统的虚拟试验台架,它能够完成对EMCVT控制系统进行初步的调试和检验工作,实现了对EMCVT控制系统的离线调试开发
[Abstract]:With the development of technology, people attach importance to energy and environmental protection, CVT (CVT) has been applied more and more in modern automobile industry. Traditional CVT has low efficiency and high failure rate due to its hydraulic system. The pure mechanical and electronic stepless transmission EMCVT electronic Mechanical Continuously Variable transmission is designed to control the clamping force and transmission ratio by using the control system of EMCVT to control the clutch motor and the speed ratio motor. In the development and debugging process of EMCVT control system, EMCVT is successively installed on the test stand and on the vehicle for experimental debugging. However, the test period of the bench test and the on-board test is long, the equipment is large, the volume is large, it is not convenient to move, and the cost is very high. Therefore, the hardware in-the-loop Simulation-HILS technology is used to simulate the test rig, and a portable hardware in loop simulation test platform is built, which provides a virtual debugging environment for the EMCVT control system in the early stage of development. In order to shorten the development cycle, reduce development costs. In this paper, the EMCVT control system of field test bench is analyzed in detail. According to the engine test data, the engine model is established by using Matlab/Simulink, and the clutch model EMCVT model is built by using the mechanical structure of the test bench. The vehicle load model and each simulation model based on LabVIEW are established. Secondly, the data acquisition module of the hardware in loop simulation platform is developed, and the software system of hardware in loop simulation platform based on LabVIEW is developed. The real-time data communication between the simulation model and the EMCVT control system and the debugging function of the control system are realized, which provides the environment for completing the virtual bench test in the laboratory. In this paper, a portable EMCVT hardware-in-the-loop simulation platform is built. As a virtual test-bed of EMCVT control system, it can complete the preliminary debugging and testing of EMCVT control system. The off-line debugging and development of EMCVT control system is realized.
