Abstract(in English) In controller area networks (CANs) on the modern electronic vehicles (EVs) and hybrid vehicles (HVs), the noise level caused by high voltage switching in DC-DC converters could be very large. On the basis of noise injection experiments using DC-DC converters, we propose an application layer-based hybrid ARQ protocol, which consists of the automatic repeat request (ARQ), forward error correction (FEC), and HALT modes. This protocol transitions to each mode by referring to the transmission and reception error counter incorporated in the CAN node. This paper indicates that the bus occupation rate per frame is less than the CAN protocol by performing the experiment using a noise injector and CAN node that implements the proposed protocol.
