Abstract: An on-board network system includes at least one processor. Plural relay devices that temporarily retain received data and relay the retained data in descending order of relay priority levels include a first relay device. For each set of data retained at the first relay device, the processor measures a retention duration for which the data is retained without being relayed. Data whose measured retention duration exceeds a predetermined threshold is congested data. A second relay device is a different relay device from the first relay device among the plurality of relay devices, and is capable of relaying the congested data. The processor requests the second relay device to raise the relay priority level of the congested data.

Abstract: A first relay device for installation at a vehicle, the first relay device comprising, a first memory and a first processor coupled to the first memory. The first processor being configured to receive a communication frame transmitted from another relay device. The first processor being configured to based on first relay information, in which destination address information expressing a destination address of a communication frame and a relay target bus are associated with each other, and based on the destination address information included in the received communication frame, identify the relay target bus. The first processor being configured to in a case in which the relay target bus of the received communication frame is not identified, output an anomaly notification signal indicating an anomaly to the other relay device.

Abstract: Provided is a grounding terminal comprising a terminal fitting including a crimp portion, and a fastened portion that is provided on the front lower side of the crimp portion and is to be connected to a grounding surface using a fastening member, the terminal fitting being provided with a stepped portion between the crimp portion and the fastened portion. A covering layer is configured to be formed on the grounding terminal by thermally shrinking a heat-shrinkable tube including, on its inner circumferential portion, a water sealing agent to be used to cover at least the crimp portion of the terminal fitting and seal the electric wire from water. A water sealing agent is configured to be distributed up to the front side with respect to the covering layer as viewed from above, and a hanging-down length d of a water sealing agent is within the range of the stepped portion.
