Study On The AMT Shift Control Strategy Of City Bus

At present, domestic factories have no ability to industrialize the automatic gear-box. In recent years, some factories are trying to seek automatic products which are suit for our country situation and can be developed independently. Due to its high efficiency, low cost, and easiness to manufacture, Automatic Manual Transmission (AMT) is considered to be the right automatic transmission format, which is suit for our country situation most and has greatest potential in the development of industrialization. We have owned the independent intellectual property and mastered the core technique. This paper is combined with AMT developing project of R&D FAW and aims at the control strategies of start and shift processes. The purpose is to research the manual shift rules of skillful drivers, to compare it with the control strategies of present sample bus with AMT, to research the differences between manual and AMT manipulation and each characteristic, to analyze the comparability index, to optimize AMT control strategies and to establish optimum control strategies through testing.This paper introduces the composing of automatic shifts gear system and the shifts gear regulation and the shift gear characteristic first, being then build up the simple motive system model of the shifting gear process, thoroughly analysis shift gear of process. on this foundation, researching...
