RT(Real-Time) CAN 시스템 구조 연구

Due to the increase of electronic control system and a variety of function improvement in vehicle, the need for safety, reliability, and convenience became an outstanding issue. Therefore, the CAN protocol has become the primary choice of protocol for real time communication sub-system within automotive electronics applications. This is despite the fact that CAN, according to many options, is unsuitable for distributed real-time applications with hard real-time requirements due to the protocol’s bus contention, non-preemptive property. In this paper, RT(Real-Time) CAN based CAN is proposed considering critical messages in CAN. We define function of Master node and describe a method of RTCAN implementation. Finally, RTCAN are simulated by CANoe.
