Field: Digital communication (Electrical engineering)
Classification: CPC H  B | IPC B  G  H

Claim 12:
13. An onboard communication system comprising:
a central onboard apparatus; and
a plurality of peripheral onboard apparatuses configured to connect to the central onboard apparatus via a first transmission path and a second transmission path, which are transmission paths of different types, wherein
each one of the plurality of peripheral onboard apparatuses are connected to the central onboard apparatus via the first transmission path on a one-to-one basis, and
at least one of the plurality of peripheral onboard apparatuses is connected via a bus connection to the central onboard apparatus via the second transmission path; wherein
the central onboard apparatus selects ones of the first transmission path and the second transmission path depending on a content of a communication information processed by the central onboard apparatus;
the second transmission path takes less time than the first transmission path to become able to communicate when transitioning from a sleep state or an inactive state to an active state; and
the control unit selects the second transmission path as the transmission path to use to transmit communication information for activation, which is the communication information for activating the other onboard apparatus.
