| Popis: | Controller area network (CAN) is a communication protocol that has been widely introduced for in-vehicle networks. Recently, CAN with flexible data-rate (CAN FD) has been suggested and it achieves higher data rate. Electronic control units (ECUs) in a vehicle communicate with each other using CAN protocol. Since more ECUs are required to establish advanced vehicle functions, we need additional wiring in a car which leads to the increase of car cost and weight. Complicated wiring topology may make communication links always fail due to the ringing. We have proposed a bipolar NRZ line coding architecture in the data phase of CAN FD to reduce the ringing. However, we need further investigation to clarify its flexibility and scalability. The simulation results show that our proposed method with high-rate CAN FD works well for more flexible and scalable wiring topology with multistage branches. |
