碩士 === 大葉大學 === 機械與自動化工程學系 === 101 === In recent years, depot of the world have been generated vehicle (including sedan, bus, car and freight), in order to comply with the requirements of the environment, enhance the continued increase safety and comfort, sensors, actuators, audio-visual equipment. Reduce the amount of vehicle wire not only reduce vehicle weight but also sharing of information on vehicle. Depot made a small LAN (Local Area Network) controller which has switched to use the CAN (Controller Area Network) architecture for connecting sensors and actuators. In this study, fault diagnosis and monitoring of electric vehicle systems have completed a set of two functional modules of the integrated system. First, devices have been programming by Flowcode, the circuit could have been set up on each node of the CAN. Based on the SAE J1939 protocol, each node can make the CAN ID (identified), each node transmits sensor information to ECU which the next control and the traffic information of the vehicle can be monitored by LabVIEW. You plan to support measures and the corresponding security node failure. In vehicle's unforeseen circumstances, you will advise when the drivers of the instrument in real-time display. ECU immediately used to support the safety of the vehicle. Developments of an integrated system, the platform to simulate the actual vehicle in this study, test the possibility of node when you view the signal transmitted through the CANKing. In the experiment, fault diagnosis and monitoring of electric vehicle systems have been developed successfully.
