Abstract(in Japanese) (See Japanese page)
Abstract(in English) Controller area network (CAN) is widely distributed as an in-vehicle communications standard. CAN-FD (CAN with Flexible Data-rate) is defined in the ISO standards to achieve higher data rate than the legacy CAN. A number of CAN nodes are able to connect with a single transmission medium, i.e. CAN enables us to constitute cost-effective bus-topology networks. CAN puts carrier sense multiple access with collision resolution (CSMA/CR) into practice by using bit-wise arbitration based on wired logical AND in the physical layer. The prioritized message is delivered without interrupting even if two or more CAN nodes transmit messages at the same time due to the bit-wise arbitration. However, the scalability of CAN networks suffers from ringing caused by wired logical AND. In this manuscript, we show our reduced wiring technology for CAN to enhance the network scalability and the cost efficiency.
