GEARSHIFT CONTROL DESIGN FOR AUTOMATED MANUAL TRANSMISSION (AMT)

Abstract

Automated manual transmission (AMT) is a type of sequential manual
transmission. It uses a traditional manual gearbox with an electronic control unit
that supervise the use of the clutch and gear shifting. The AMT combines the
advantages of a automatic transmission and a manual one, such that: comfort
driving, fuel economic driving and dynamics driving. One of the problems of a
AMT is the automated gear shifting. In this paper, the authors develope a
gearshift mechanism model, simulate the processe of gear shifting and research
influence of the fork force on the gear shifting time.
