CAN(Controller Area Network) Bus Communication System Based on Matlab/Simulink

CAN bus communication system was established mainly using SimEvents module in the software of Matlab/Simulink. Performance indexes of CAN bus system, which embraces worst-case response time of messages and bus load, were separately gained by theoretical calculation, experiments in Matlab and CANoe. The calculation and experiment results were compared sufficiently, and it concludes that CAN bus system established in Matlab/Simulink can efficiently represent the message transfer sequences on the CAN bus, and achieve an exact result of the performance analysis of the CAN bus system. With CAN bus system established in Matlab/Simulink, test modules for ECU (Electric Control Unit) testing can conveniently be created, and it is an efficient testing tool for CAN bus system design.
