Abstract: A gateway device for a vehicle network system installed in a vehicle is provided. The vehicle network system includes a network, an electronic control unit connected to the network, and the gateway device connected to the first network and configured to communicate outside the vehicle. The gateway device receives a first frame from outside the vehicle; determines whether or not the first frame is appropriate; generates a second frame when the first frame is not determined to be appropriate; and transmits the second frame to the network. The second frame includes control information and additional information based on content of the first frame. The control information restricts processing of the additional information included in the second frame by the electronic control unit, after the second frame is received by the electronic control unit.

Abstract: An in-vehicle relay device prevents an anomaly of a control command exchanged over networks having different transmittable data sizes in a frame. The in-vehicle relay device relays communication between multiple control devices in a vehicle over the networks to which the control devices are connected. The in-vehicle relay device receives control data from a first control network. The control data includes, in a frame, a plurality of control commands to be executed by at least one of the control devices. The in-vehicle relay device determines, as a first determination, whether types of the control commands included in the frame form a first combination that is preset as a combination of control commands that are executable simultaneously. The in-vehicle relay device thereafter determines, as a second determination, whether the control data is anomalous by using the result of the first determination, and outputs the result of the second determination.

Abstract: A network hub is provided for an onboard network system. The onboard network system includes first and second networks for transmission of first-type and second-type frames following first and second communication protocols. The network hub includes a receiver that receives a first-type frame. A processor determines whether or not the first-type frame received by the receiver includes first information that is a base for a second-type frame to be transmitted to the second network, to obtain a determination result, and selects a port to send a frame based on the first-type frame based on the determination result. A transmitter sends the frame based on the first-type frame to a wired transmission path connected to the port selected by the processor based on the first-type frame received by the receiver.

Abstract: A vehicle monitoring apparatus includes: a first communicator that receives specifying information for specifying a target vehicle from a server; and an acquirer that acquires driving information from the target vehicle, the driving information being information regarding driving of the target vehicle specified by the specifying information received by the first communicator. The first communicator transmits the driving information acquired by the acquirer to the server. For example, the acquirer may acquire the driving information obtained from the target vehicle through communication.
