AMT Fault Information System Based on CAN Bus Gateway

Abstract

AMT fault information system based on CAN bus power gateway is designed for the requirements of fault diagnosis in AMT system of vehicle. The functional intergration of data communication in gateway and management of AMT fault data are realized by adding chips of Flash, EEPROM, DS1302, etc. based on the hardware platform of gateway, meanwhile, improving relevant software program. It provides vast analysis data for fault diagnosis and also improves the accuracy of fault diagnosis. The real vehicle test indicates that the system is stable, reliable and practical. This system plays an important role in fault diagnosis of vehicle transmission and data communication of vehicle in motion.
