Enabling Efficient V2V Communication through CAN Gateway Integration

Vehicle-to-vehicle (V2V) communication is a pivotal aspect of modern automotive technology, facilitating wireless data exchange among motor vehicles. This paper presents a comprehensive study aimed at enhancing V2V communication by incorporating the controller area network (CAN) gateway mechanism. CAN gateways play a crucial role in intelligent transportation systems, harnessing technology to optimize traffic flow and enhance road safety. The paper focuses on data accuracy, with transmitted information consistently formatted in 8-byte sequences. Data transfer rates, ranging from 1 kbit per second to 1 Mbit per second, are examined, particularly in the context of high-speed CAN gateways. To accommodate extensive data transfers, the CAN-FD gateway is introduced, supporting 64-byte data packets and data transfer speeds spanning 1 Mbps to 8 Mbps. The study employs specialized functions for efficient data packing into either 8-byte or 64-byte formats, ensuring secure packet formation and subsequent interpretation by the appropriate CAN gateway. Experimental simulations demonstrate that CAN data transmitted to different electronic control units (ECUs) within one vehicle can be successfully interpreted by another, establishing robust and effective V2V communication capabilities.
