CAN gateway for fast vehicle to vehicle (V2V) communication

Intelligent transport systems (ITS) use information and communication technologies to improve vehicle safety on roadways and effective traffic flow management. A vehicle communicates with other vehicles and/or infrastructures with wired/wireless communication technologies. In-vehicle networks are composed of numerous electronic control units (ECUs) according to the type of service in various domains (e.g. powertrain domain, body domain, and chassis domain). Vehicle to vehicle (V2V) messages related to vehicle safety should meet low-latency requirements. In addition, the information contained in V2V messages is associated with specific ECUs. For the interworking between the V2V communications and in-vehicle networks, we should consider a new method that responses necessary ECUs for specific V2V message. In this paper, we propose an effective controller area network (CAN) gateway method. This method uses CAN gateway searching for a network table based on the CAN frame for V2V message. Because of simple structure and method, the proposed method can be a good solution that controls the ECUs with ease. And it also can make V2V messages at high speed.
