| Abstract(in English) | Controller area network (CAN) is a communication standard that is widely employed for in-vehicle networks, and electronic control units (ECUs) in a car communicate with each other using CAN. CAN needs to enhance the bit rate as ECUs are becoming high performance so that CAN with flexible data-rate (CAN FD) has been proposed for the next generation standard. CAN communications employ unipolar non-return-to-zero (NRZ) line codes to establish the arbitration function. The bit duration in the data phase shortens with higher bit rate so that the bit reliability will deteriorate due to ringings originated from reflected waves of signals. As a result, a sending node might stop transmitting if it detects the discrepancy between the sending bit and the bus voltage in the data phase. In this manuscript, we propose to employ bipolar NRZ line coding architecture with existing CAN transceivers in the data phase of CAN FD to reduce the influence of ringings. The simulation results show that our proposed line coding architecture attains higher bit rate than the conventional one in networks conforming to the CAN standard. |
