Performance Analysis of Controller Area Network

Abstract

Controller Area Network (CAN) is widely used in automotive and industrial areas. To give guidance in the design process, CAN bus communication model is established using Matlab/SimulinkTM. Considering the error frames on the bus, the formula that calculating CAN response time and bus load is revised. The relating performance indexes of CAN bus is gained separately through calculation and simulation, it concludes that the CAN bus communication model can efficiently simulate the message transfer sequences in the real bus, and achieves an exact result of the performance analysis of the CAN bus system.
