自动换挡规律的研究

STUDY ON THE AUTOMATIC SHIFT LAW

在自动变速器的开发过程中，提出了边界点换挡规律，并对换挡规律的制定进行了研究，提出了新的方法。在此基础上制定了桑塔纳 ２０００ 机械式自动变速器（ Ａ Ｍ Ｔ）的换挡规律，并在实际跑车中得到检验，这对于 Ａ Ｍ Ｔ 的产品化和提高我国自动变速器的自主开发能力有重要的意义。

During the exploiting of automatic transmission, the boundary points shift law is previewed, and the new methods to make the shift law are proposed. Based on these, the shift law of Santana2000 AMT (Automated mechanicl transmission) is given, which is proved by the actual run. All of these have theoretical and practical value to develop national automatic transmission.
