In this paper, a multi-node data acquisition and analysis system for the development of AT ECU (electronic control unit)is designed. The system acquires data from each node on the bus and sends the data to PC through CAN card, while designing data display, storage and analysis system on PC through LabVIEW8.6 platform in order to monitor control signals and state parameters of the automatic transmission in real-time. This system can improve the efficiency of data processing and shorten the development cycle for ECU by analyzing the data acquired.
