Gateway system for CAN and FlexRay in automotive ECU networks

Automotive gateway system is necessary because several communication protocols is used and need to communicate between other. CAN bus is one of the most popular buses, and FlexRay has the unique advantages of high speed, large bandwidth and reliability. In this paper, a gateway for CAN and FlexRay in automotive has been proposed. The gateway can convert data between CAN and FlexRay protocols that minimize the differences frame format, communication paradigm and speed, through using Gateway Global Algorithm. In addition, the gateway system can return conversion result that presents on PC with USBCAN.
