In-vehicle ethernet communication system and communication method thereof

摘要

A first device, which is any one of a plurality of devices communicating with each other using an Ethernet scheme in the in-vehicle Ethernet communication system includes: a central processor, and a physical layer processor to connect the central processor to a second device which is another one of the plurality of devices, wherein the physical layer processor includes a counter to output a first counting end signal, a signal transmitter to demand that the first device continuously operate in response to receiving at least one of a mode signal and the first counting end signal, a signal receiver to output a master sensing signal, and an operation mode controller to determine an operation mode of the first device in response to receiving at least one of the first counting end signal and the master sensing signal and to generate the mode signal.
