Co-simulation of SBW and FlexRay bus based on CANoe_MATLAB

Abstract

Steer-by-wire is such a technology that replaces the traditional mechanical and hydraulic control systems by electronic control systems. As the next generation automotive network communications protocol, FlexRay meets the future demands of steer-by-wire network. This paper builds the co-simulation model of steer-by-wire and FlexRay bus on the basis of CANoe_MATLAB, which combines the advantages of CANoe(bus) and Matlab /Simulink (modeling) together, Steer-by-wire is simulated by Matlab /Simulink, FlexRay bus network is simulated by CANoe, which also verified by the hardware in loop. The tests are shown that SBW FlexRay communication between nodes is real time and accurate.
