【摘要】：隨著科學(xué)技術(shù)的發(fā)展,無級變速器(CVT)越來越多的應(yīng)用于現(xiàn)代汽車。本課題以純機械電子式無級變速器EMCVT (Electronic Mechanical Continuously Variable Transmission)為研究對象,拋棄了不夠理想的液壓系統(tǒng),具有很大的研究價值和發(fā)展空間。為了能夠使EMCVT發(fā)揮其功效,需要開發(fā)一套使EMCVT汽車具有良好操控性、駕駛舒適并具有理想的動力性和燃油經(jīng)濟性的控制系統(tǒng)。根據(jù)EMCVT機械結(jié)構(gòu)和變速原理,控制系統(tǒng)就是要控制速比控制電機和離合器控制電機。 EMCVT控制系統(tǒng)調(diào)試最簡單有效的方式,就是將EMCVT直接安裝到試驗臺架和汽車上進行實驗,但是臺架試驗和車載試驗的試驗周期都比較長,需要的試驗設(shè)備多,成本很高,不利于控制系統(tǒng)的改進,而且現(xiàn)場試驗難實現(xiàn)一些極端情況,甚至?xí)幸恍┪ｋU發(fā)生。因此,本文根據(jù)現(xiàn)場試驗情況通過對硬件在環(huán)仿真(Hardware-in-the-loop Simulation-HILS)理論的研究,開發(fā)了用于EMCVT控制系統(tǒng)初期調(diào)試的硬件在環(huán)仿真試驗平臺(HILSP),它為控制系統(tǒng)提供了虛擬調(diào)試環(huán)境,使得控制系統(tǒng)初期調(diào)試只需要在實驗室就能夠完成。 本課題來源于遼寧省科學(xué)技術(shù)計劃工業(yè)攻關(guān)重點項目：車用無級變速器實驗與控制關(guān)鍵技術(shù)攻關(guān),并根據(jù)EMCVT的控制系統(tǒng)和現(xiàn)場的臺架試驗和車載試驗,本文首先分析了EMCVT的機械結(jié)構(gòu),同時根據(jù)機械結(jié)構(gòu)和試驗數(shù)據(jù)建立了發(fā)動機模型、EMCVT模型、汽車負(fù)載模型,并在Matlab/Simulink中驗證這些模型的可行性,用數(shù)學(xué)模型實現(xiàn)控制系統(tǒng)的離線調(diào)試。 其次,通過對硬件在環(huán)仿真理論的研究,本文編寫了基于LabVIEW的硬件在環(huán)仿真程序,使仿真程序與控制系統(tǒng)實現(xiàn)實時通訊,具有控制系統(tǒng)調(diào)試功能。 最后,編寫友好的硬件在環(huán)仿真程序人機交互界面,方便、清晰的顯示出當(dāng)前車載試驗狀態(tài),并通過仿真試驗分析了開發(fā)的硬件在環(huán)仿真平臺能夠滿足控制系統(tǒng)需求,達到控制系統(tǒng)初期調(diào)試目的。
[Abstract]:With the development of science and technology, continuously variable transmission (CVT) is more and more used in modern automobile. This subject takes the pure mechanical electronic stepless transmission EMCVT (Electronic Mechanical Continuously Variable Transmission) as the research object, abandons the not ideal hydraulic system, has the great research value and the development space. In order to enable EMCVT to play its role, it is necessary to develop a set of control system which can make EMCVT car have good handling, comfortable driving and ideal power and fuel economy. According to EMCVT mechanical structure and variable speed principle, the control system is to control the speed ratio control motor and clutch control motor. The simplest and effective way to debug the EMCVT control system is to install the EMCVT directly on the test bench and the automobile to carry on the experiment, but the test period of the bench test and the on-board test is relatively long, the test equipment required is more, and the cost is very high. It is not conducive to the improvement of the control system, and the field test is difficult to achieve some extreme situations, and even some dangers occur. Therefore, according to the field test, the hardware-in-the-loop simulation (Hardware-in-the-loop Simulation-HILS) theory is studied, and the hardware-in-loop simulation test platform (HILSP),) is developed for the initial debugging of EMCVT control system. It provides a virtual debugging environment for the control system, so that the initial debugging of the control system only needs to be completed in the laboratory. This topic comes from the key project of Liaoning province science and technology plan industrial key problem: vehicle CVT experiment and control key technology, and according to EMCVT control system and field bench test and on-board test, In this paper, the mechanical structure of EMCVT is firstly analyzed, and the engine model, EMCVT model and vehicle load model are established according to the mechanical structure and test data, and the feasibility of these models is verified in Matlab/Simulink. The off-line debugging of control system is realized by mathematical model. Secondly, through the research of hardware-in-loop simulation theory, the hardware-in-the-loop simulation program based on LabVIEW is compiled in this paper, which makes the simulation program communicate with the control system in real time and has the debugging function of the control system. Finally, the friendly man-machine interface of hardware-in-the-loop simulation program is compiled to display the current vehicle test status conveniently and clearly. The hardware-in-the-loop simulation platform developed can meet the requirements of the control system through simulation experiments. Achieve the purpose of initial debugging of the control system.
