Abstract
To improve the performance of AMT, many researches have been done to perfect the shift schedule and the clutch control performance. The new type of actuators of clutch and gearbox driven by motors are introduced, which are easy to manufacture, install and control compared to the hydraulic actuators. During the exploiting of automated mechanical 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 of Shanghai VW is given, which is proved by the actual run. All of these have theoretical and practical value to develop national automatic transmission.
