Abstract
A central control device and a plurality of relay devices constitute a backbone network. Each of the relay device includes: a backbone-side communication port connected to a backbone network; a plurality of device-side communication ports configured to input and output a signal to/from an onboard device; and a first interface conversion device configured to perform interface conversion between the backbone-side communication port and the device-side communication ports. The device-side communication ports include a plurality of general-purpose communication ports to which a common input circuit and/or output circuit is connected. A predetermined first onboard device is directly connected to the general-purpose communication ports, whereas a predetermined second onboard device is connected to the general-purpose communication ports via a predetermined first onboard device.
