摘要
随着节能和环保要求的日益提高,能够连续改变传动比,进而改善汽车动力性、经济性和排放指标的无级变速器成为汽车变速器的主要发展方向。在简单说明采用无级变速器的原因之后,对当前汽车无级变速器的主要形式———金属带式无级变速器的工作原理和发展过程进行了详细介绍;并对当前基于无级变速器的汽车动力传动系的主要控制方法做了简单分析,分别阐述了在不同工况下的控制方法以及先进控制理论在基于无级变速器的控制中的应用。
With the increasing demand of fuel economy and emissions, continuously variable transmission (CVT) which can improve drivability, fuel economy and emissions by changing gear ratio continuously became the main development trend of automotive transmissions. Metal V-belt CVT was introduced as the main kind of CVT and the modeling of CVT-based powertrain were described. According to different operations, different control approaches were discussed and fuzzy control in the CVT-based powertrain control was presented.
