Title:

VEHICLE-MOUNTED RELAY DEVICE, VEHICLE-MOUNTED COMMUNICATION SYSTEM, COMMUNICATION PROGRAM, AND COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2021/024739

Kind Code:

A1

Abstract:

Provided are a vehicle-mounted relay device, a vehicle-mounted communication system, a communication program, and a communication method, with which it can be expected that bad effects due to connection of an inappropriate device to a communication line in a vehicle are reduced.　In the vehicle-mounted relay device according to this embodiment, a plurality of communication lines mounted in a vehicle are connected, and data transmission and reception are relayed among the plurality of communication lines, the vehicle-mounted relay device comprising: a relay restriction unit that restricts the relay to another communication line of data transmitted by a communication device newly connected to one communication line; a behavior analysis unit that analyzes the operation of the communication device on the basis of an input value to the communication device, and correspondence information for the operation result of the communication device in accordance with the input value; and a restriction release unit that releases the restriction of relays by the relay restriction unit in accordance with the result of the analysis by the behavior analysis unit.
