As the key technology to realize the industrialization of continuously variable transmission , starting control is absolutely necessarily 要實現(xiàn)無級自動變速器的產(chǎn)業(yè)化,起步控制是必不可少的關鍵技術。
Nowadays automatic gear shifting is divided into three sorts : automatic transmission ( at ) , continuously variable transmission ( cvt ) , and automatic mechanical transmission ( amt ) 當今車輛自動變速器分為三類,它們分別是:液力機械自動變速器( at ) 、機械無級自動變速器( cvt )以及電控機械式自動變速器( amt ) 。
Based on the basic analysis of the structure and power elements of the hybrid vehicle , this thesis presents a powertrain system with a metal pushing belt cvt , aiming to the development status and trend of the hybrid vehicle technology in our country . a rational control strategy and its work mode of this powertrain system are determined , and correlative parameters such as the engine power , the starting torque , and the differential ratio , the rated power and torque of the motor , and the ratio of the torque synthesizer are systematically designed for the changan star 6350b . at the same time , the design of these parameters is considered as the base of the simulation of the motor control system in next step 在對混合動力汽車的結構型式和動力元件進行基礎性理論分析后,針對我國汽車技術發(fā)展現(xiàn)狀和混合動力汽車技術的發(fā)展趨勢,設計了一種基于金屬帶式無級自動變速器cvt混合動力汽車動力傳動系統(tǒng)方案,根據(jù)該傳動系統(tǒng)方案制定了比較合理的控制策略和工作模式,并針對長安之星6350b設計了發(fā)動機功率和起始轉矩、主減速比、電機的額定功率和轉矩、轉矩合成器速比等相關參數(shù),為下一步的電機控制系統(tǒng)仿真實驗打下基礎。
