汽车发动机与传动系联合操纵的研究

为实现电控机械式自动变速系统的统一控制,本文展开了以下三个方面的研究:首先,为该系统建立了一种最佳变速特性曲线;其次,为其加速踏板设计了一种稳定实用的踏板工作曲线;最后,通过动力分析,确定了在换档过程中,系统各总成应采取的控制策略。

Research on United Control of Engine and Transmission

A study has been carried out on the operation of the automatic mechanical transmission (AMT) under a united control. This paper describes an optimum shift schedule with appropriate engine control for the AMT. And a kind of operating curve is worked out for the accelerating pedal of the AMT. Finally, some control strategy for each assembly in the system including engine and transmission during shifting are discussed.
