【摘要】：隨著技術(shù)的發(fā)展、人們對能源和環(huán)保的重視,無級變速器(CVT)在現(xiàn)代汽車產(chǎn)業(yè)得到了越來越多的應(yīng)用。傳統(tǒng)的CVT由于其液壓系統(tǒng)的低效率和高故障率,使其得不到推廣使用。而本文研究的純機械電子式無級變速器EMCVT (Electronic Mechanical Continuously Variable Transmission)則是利用EMCVT的控制系統(tǒng)對離合器電機和速比電機的控制來實現(xiàn)對夾緊力和傳動比的控制。 EMCVT控制系統(tǒng)開發(fā)調(diào)試過程,是把EMCVT先后安裝到試驗臺架和汽車上進(jìn)行實驗調(diào)試,但臺架試驗和車載試驗的試驗周期長、設(shè)備多、體積大、不便于移動、成本很高、而且極端情況安全性不足。所以本文利用硬件在環(huán)仿真(Hardware-in-the-loop Simulation-HILS)技術(shù)對試驗臺架進(jìn)行仿真,搭建便攜式硬件在環(huán)仿真試驗平臺(HILSP),為EMCVT控制系統(tǒng)在開發(fā)初期提供了虛擬調(diào)試環(huán)境,以縮短開發(fā)周期、降低開發(fā)成本。 本文首先對仿真對象EMCVT.現(xiàn)場試驗臺架、EMCVT控制系統(tǒng)作了詳細(xì)的分析,根據(jù)發(fā)動機的試驗數(shù)據(jù)利用Matlab/Simulink建立了發(fā)動機模型,利用試驗臺架的機械結(jié)構(gòu)建立起了離合器模型、EMCVT模型、汽車負(fù)載模型,并且建立了基于LabVIEW的各個仿真模型。其次本文開發(fā)了該硬件在環(huán)仿真平臺的數(shù)據(jù)采集模塊,編寫了基于LabVIEW的硬件在環(huán)仿真平臺軟件系統(tǒng),實現(xiàn)了仿真模型與EMCVT控制系統(tǒng)之間的實時數(shù)據(jù)通訊和對控制系統(tǒng)的調(diào)試功能,為其提供了在實驗室完成虛擬臺架試驗的環(huán)境。 本文最終搭建起了一個便攜式EMCVT硬件在環(huán)仿真平臺,作為EMCVT控制系統(tǒng)的虛擬試驗臺架,它能夠完成對EMCVT控制系統(tǒng)進(jìn)行初步的調(diào)試和檢驗工作,實現(xiàn)了對EMCVT控制系統(tǒng)的離線調(diào)試開發(fā)
[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.
