Development of End of Line CAN Bus Test System in Electric Vehicles Based on LabVIEW

Abstract

With the wildly application and development of CAN bus technology in the electric vehicles domain, the majority of domestic automobile manufacturers will introduce CAN bus to more and more cars, and the techniques and methods of testing these cars also need to be updated and developed. The traditional means of detection and diagnosis, cannot fully meet the need of the cars' production test, maintenance and diagnostics of body distributed control technology. In this paper, a scheme of the system with a portable computer is establish for the practical application to the EOL CAN bus test, and then design and research of the testing system software are followed. To develop establish the system scheme, we study in depth and explore test methods and management, and design two test modes which are manual monitoring mode and automatic monitoring mode in view of the practicality and re-usability of the test system. In the process of system software development, we program in LabVIEW, make a research and optimization of Microsoft office accesss database connection for both software, and design user interface program of database maintenance and management finally.
