The vehicle-mounted relay device in a vehicle-mounted communication system provided with a plurality of vehicle-mounted devices, the vehicle-mounted relay device includes: 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.

Vehicle-mounted relay device, vehicle-mounted communication system, and communication control method

A vehicle-mounted relay device for relaying Ethernet frames includes a plurality of PHY units corresponding to a plurality of vehicle-mounted devices, a switch unit to which the plurality of PHY units are connected, and a control unit configured to monitor operating states of the plurality of PHY units. The plurality of PHY units include a predetermined PHY unit whose operating state switches between a sleep state and an active state in response to reception of a predetermined control signal that differs from the Ethernet frames. When an Ethernet frame to be transmitted from the predetermined PHY unit has been detected during a period where the predetermined PHY unit is in the sleep state, the control unit executes switching control to switch the predetermined PHY unit to the active state.

Relay device, relay system, relaying method, and computer program

A management device includes: a specification information acquisition unit configured to acquire specification information indicating a specification of a configuration of an in-vehicle network; a state information acquisition unit configured to acquire state information indicating an assembly state, in the in-vehicle network, of a plurality of in-vehicle devices forming the in-vehicle network; and a comparison unit configured to compare the specification indicated by the specification information acquired by the specification information acquisition unit with the assembly state indicated by the state information acquired by the state information acquisition unit.

Management device, inspection method, and inspection program

The in-vehicle management device includes: a detection unit configured to detect the presence of a target device that is an in-vehicle device that does not support a predetermined message among in-vehicle devices included in an in-vehicle network; and a control unit configured to perform control for causing the target device detected by the detection unit to transition to a sleep state when a state where the predetermined message from the in-vehicle devices does not arrive at the in-vehicle management device has continued for a predetermined period.
