Abstract
An in-vehicle communication system includes a first switching device and a second switching device each configured to relay, via a transmission path, information between a plurality of function units mounted to a vehicle. Upon being supplied with a power source voltage via a power-source-dedicated line from a power source device mounted to the vehicle, the first switching device supplies a power source voltage via the transmission path to one or a plurality of the function units and the second switching device that are connected to the first switching device, and the second switching device extracts a power source voltage from the transmission path, and supplies a power source voltage via the transmission path to one or a plurality of the function units that are connected to the second switching device.
