Automotive manufacturers are trying to replace mechanical control systems with electronic control systems. Steer-by-wire and brake-by-wire systems are among those to be replaced. As a result, Electronic Control Unit (ECU) usage is increasing sharply. The In-Vehicle Network (IVN) is more complex now than in the past, and the amount of communication data is increasing rapidly. Many kinds of network protocols (LIN, CAN, FlexRay, MOST, Ethernet) use IVN. Therefore, a flexible gateway embedded system is both important and necessary. The gateway embedded system can improve IVN reliability and compatibility. This paper presents a CAN, FlexRay Gateway Embedded System with function actively handling CAN messages. This gateway has specific functions of automatically reducing CAN frame overhead and relieving CAN bus traffic, yield many advantages for the real-time performance of the IVN.
