Claims15
A vehicle-mounted relay device in a vehicle-mounted communication system provided with a plurality of vehicle-mounted devices, the vehicle-mounted relay device comprising:
- a relay unit configured to relay communication data between the plurality of vehicle-mounted devices;
- and
- a processing unit configured to, before communication is started between the vehicle-mounted devices, notify the vehicle-mounted devices of a common protocol that is a common communication protocol to be used.
A vehicle-mounted communication system comprising:
- a plurality of vehicle-mounted devices including a vehicle-mounted relay device,
- wherein the vehicle-mounted relay device is configured to relay communication data between the plurality of vehicle-mounted devices,
- the vehicle-mounted relay device is configured to notify, before communication is started between the vehicle-mounted devices, the vehicle-mounted devices of a common protocol that is a common communication protocol to be used, and
- upon receiving a notification of the common protocol, the vehicle-mounted devices determine whether or not to switch to communication using the common protocol.
A communication control method that is performed by a vehicle-mounted relay device included in a vehicle-mounted communication system provided with a plurality of vehicle-mounted devices, the vehicle-mounted relay device relaying communication data between the plurality of vehicle-mounted devices, the method comprising:
- a step of selecting, before communication is started between the vehicle-mounted devices, a common protocol that is a common communication protocol to be used, and
- a step of notifying the vehicle-mounted devices of the selected common protocol.
