IN-VEHICLE RELAY APPARATUS AND COMMUNICATION SYSTEM

摘要

An in-vehicle relay apparatus can restrict transmission of identification information with which a vehicle can be specified to the outside of the vehicle. A vehicle internal communication unit may communicate with at least one in-vehicle device installed in a vehicle, and a vehicle external communication unit may communicate with a vehicle external communication device disposed outside of the vehicle. A communication processing unit may add identification information to relay information that is transmitted to the vehicle external communication device. The identification information may regard a transmission source of relay information by which the vehicle external communication device determines the transmission source of the relay information. Additionally, the communication processing unit may transmit, using the vehicle external communication device, the relay information to the vehicle external communication device. A determination unit may determine which information is used as the identification information based on stored access authority levels.

主权项

1. An in-vehicle relay apparatus for relaying communication between an in-vehicle device and a vehicle external communication device disposed outside of the vehicle, the in-vehicle relay apparatus comprising:
a vehicle internal communication unit configured to communicate with at least one in-vehicle device installed in a vehicle; a vehicle external communication unit configured to communicate with the vehicle external communication device; a communication processing unit configured to (1) add identification information to relay information to be transmitted to the vehicle external communication device, the identification information regarding a transmission source of the relay information by which the vehicle external communication device can determine the transmission source of the relay information, and to (2) transmit to the vehicle external communication device, using the vehicle external communication unit, the relay information to which the identification information is added; an acquiring unit configured to acquire first information stored in a storage unit; a creation unit configured to create second information that is different from the first information; and a determination unit configured to determine which of the first information and the second information the communication processing unit is to use as the identification information,
wherein the communication processing unit is further configured to transmit the relay information to the vehicle external communication device using, as the identification information, either the first information or the second information depending on a result of the determination unit.
