自动变速箱换档过程建模方法比较

Compare of Modeling Method of Shift Process of Automatic Transmission

研究自动变速箱换档过程时,常用的简化模型忽略了发动机和液力变矩器的动态特性,仿真结果不够准确。本文将发动机平均值模型和液力变矩器的动态模型引入到变速箱换档过程的研究中,提出了一个新的建模方法,更准确的反映自动变速箱换档过程。

A simplified model is usually used in the research of shift process of automatic transmission. In this model the dyn modeling method i of conversion, can amic characteristic is ignored, so the result of simula s presented. This model includes the mean-value mo reflect shift process of automatic transmission more tion is not exact. In this paper a new del of engine and the dynamic model exactly.
