Abstract

In this paper, a research about air-drive AMT (automatic mechanical transmission) fault diagnostic system is made. The redundancy analysis method and action analysis method are used to detect the failures in the AMT system and a fault diagnostic system of air-drive AMT in heavy commercial vehicle is developed by model based design which is very adapt to the development of automotive control system. The fault diagnostic models of sensors and execute components in AMT system are successfully built in Matlab/Simulink. The fault diagnostic models are implemented through a RCP (rapid control prototyping) experiment based on dSPACE.
