Zusammenfassung:A relay device (20) connected to an in-vehicle network includes a first determination unit (21, 22); a second determination unit (25); and a relay processing unit (26, 27). The first determination unit is configured to send out a high priority transfer message through a first path that runs from the first determination unit to the relay processing unit without passing through the second determination unit. The relay processing unit is configured to output the high priority transfer message, acquired through the first path, to the second determination unit and the in-vehicle device. The first determination unit is configured to send out a normal priority transfer message to the relay processing unit through a second path that runs from the first determination unit to the relay processing unit via the second determination unit. The relay processing unit is configured to output the normal priority transfer message, acquired through the second path, to the in-vehicle device.
