1. An in-vehicle network system comprising:
a central processing: unit coupled to a trunk network;
a network hub device provided in a vehicle body and coupled to the trunk network through which a digital control signal of a first protocol is transmitted from the central processing unit to the network hub device; and
a sub hub device configured to perform input/output of a signal to/from at least one in-vehicle device provided in a partial body assembled to the vehicle body via a movable portion, wherein
the sub hub device is provided in the partial body and is configured to transmit/receive a digital control signal of a second protocol to/from the network hub device via a wire harness passing through the movable portion,
the network hub device is configured to convert the digital control signal of the first protocol received through the trunk network to the digital control signal of the second protocol and to transmit the digital control signal of the second protocol to the sub hub device, and
the network hub device is further configured to convert the digital control signal of the second protocol received from the sub hub device to the digital control signal of the first protocol and to transmit the digital control signal of the first protocol to the trunk network.
