In-vehicle relay device, in-vehicle system, information processing method, and a program

Abstract

An in-vehicle relay device to be connected to a plurality of in-vehicle devices mounted on a vehicle and an authentication device performing authentication of the in-vehicle device, to relay communication between the plurality of in-vehicle devices, the device including a control unit controlling the relay of the communication, in which the control unit relays authentication communication data for the authentication between the in-vehicle device and the authentication device before the authentication of the in-vehicle device connected to the in-vehicle relay device is completed, transmits and receives setting data for setting an in-vehicle network with the authentication device and the in-vehicle device, in parallel with the relay of the authentication communication data, acquires setting information of the in-vehicle network according to the transmitted setting data, from the authentication device, and starts relay based on the acquired setting information after the authentication is completed.
