In order to make automatic mechanical transmission (AMT) capable of performing fault self-diagnoses and adaptive to standard communication interface, through technical analysis and intensive study concerning on-board diagnostic protocols now widely applied in Europe and America, KWP2000 on CAN is accepted as a technological path. An AMT fault communication system using hardware-in-the-loop simulation by dSPACE is developed, and communications compatible with ISO 15031-6 is realized on this module. Moreover, a hand-held fault diagnosis instrument with built-in software is designed to facilitate communications with AMT fault communication module with accuracy, rapidity and stableness. Bench and real vehicle experimental results show that the developed instrument and module can perform the anticipated functions, so as to maintain steady communications under the KWP2000-on-CAN protocol.
