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.

First claim

Opening claim text (preview).

The invention claimed is: 1 . 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 in-vehicle relay device comprising a control unit controlling the relay of the communication, wherein 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 in-vehicle device and the authentication 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. 2 . The in-vehicle relay device according to claim 1 , wherein the setting data includes at least one of destination information for performing communication and service resolution information for the in-vehicle device to start provision of a function, and the control unit outputs at least one of the acquired destination information of the in-vehicle device and service resolution information, and destination information of the in-vehicle relay device to the authentication device before the authentication is completed. 3 . The in-vehicle relay device according to claim 1 , wherein the in-vehicle device includes an existing in-vehicle device mounted in advance on the vehicle, and an additional in-vehicle device mounted on the vehicle at a time point after a time point when the existing in-vehicle device is mounted on the vehicle, and the authentication is performed with respect to the additional in-vehicle device. 4 . The in-vehicle relay device according to claim 1 , wherein the in-vehicle relay device is provided between the authentication device and the in-vehicle device. 5 . An in-vehicle system, comprising: the authentication device; and the in-vehicle relay device according to claim 1 , wherein the in-vehicle relay device outputs the setting data to the authentication device before the authentication of the in-vehicle device is completed, and the authentication device receives the setting data output from the in-vehicle relay device, and outputs the setting information according to the received setting data to the in-vehicle relay device. 6 . An information processing method performed by an in-vehicle relay device 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 method comprising: relaying 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; transmitting and receiving setting data for setting an in-vehicle network with the in-vehicle device and the authentication device, in parallel with the relay of the authentication communication data; acquiring setting information of the in-vehicle network according to the transmitted setting data, from the authentication device; and starting relay based on the acquired setting information after the authentication is completed. 7 . A computer program product for allowing a computer, 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 computer program product comprising a non-transitory, machine-readable medium storing instructions which, when executed by at least one programmable processor, caused at least one programmable processor to execute processing of: relaying 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 computer is completed; transmitting and receiving setting data for setting an in-vehicle network with the in-vehicle device and the authentication device, in parallel with the relay of the authentication communication data; acquiring setting information of the in-vehicle network according to the transmitted setting data, from the authentication device; and starting relay based on the acquired setting information after the authentication is completed. 8 . The in-vehicle relay device according to claim 2 , wherein the in-vehicle relay device is provided between the authentication device and the in-vehicle device. 9 . The in-vehicle relay device according to claim 3 , wherein the in-vehicle relay device is provided between the authentication device and the in-vehicle device. 10 . An in-vehicle system, comprising: the authentication device; and the in-vehicle relay device according to claim 2 , wherein the in-vehicle relay device outputs the setting data to the authentication device before the authentication of the in-vehicle device is completed, and the authentication device receives the setting data output from the in-vehicle relay device, and outputs the setting information according to the received setting data to the in-vehicle relay device. 11 . An in-vehicle system, comprising: the authentication device; and the in-vehicle relay device according to claim 3 , wherein the in-vehicle relay device outputs the setting data to the authentication device before the authentication of the in-vehicle device is completed, and the authentication device receives the setting data output from the in-vehicle relay device, and outputs the setting information according to the received setting data to the in-vehicle relay device. 12 . An in-vehicle system, comprising: the authentication device; and the in-vehicle relay device according to claim 4 , wherein the in-vehicle relay device outputs the setting data to the authentication device before the authentication of the in-vehicle device is completed, and the authentication device receives the setting data output from the in-vehicle relay device, and outputs the setting information according to the received setting data to the in-vehicle relay device. 13 . The in-vehicle relay device according to claim 2 , wherein the in-vehicle device includes an existing in-vehicle device mounted in advance on the vehicle, and an additional in-vehicle device mounted on the vehicle at a time point after a time point when the existing in-vehicle device is mounted on the vehicle, and the authentication is performed with respect to the additional in-vehicle device.
