    摘要： An in-vehicle network system includes a plurality of first controllers; a plurality of first communication lines, the first communication lines being respectively connected to the first controllers; a connector that connects an external device or a wireless communication device; a connection communication line that is connected to the connector; and a first relay device that relays between the first communication lines and the connection communication line. The first relay device is configured to determine whether a security level in data communication between the first controllers is increased according to a type of the external device or a communication state of the wireless communication device in a state in which the external device or the wireless communication device is connected to the connector, and the first relay device is configured to increase the security level when the first relay device determines that the security level is increased.

    摘要： A communication system including two communication nodes communicably connected in a full duplex communication mode via the same communication line is provided. Each of the two communication nodes includes a first processing unit configured to be able to send a predetermined monitoring frame to another communication node at predetermined intervals and to receive the predetermined monitoring frame from the other communication node at predetermined intervals; a second processing unit configured to detect a monitoring frame missing condition wherein the monitoring frame is received from the other communication node; and a third processing unit configured to switch communication with the other communication node from the full duplex communication mode to a half duplex communication mode when a predetermined condition is satisfied during communication in the full duplex communication mode wherein the predetermined condition includes a condition that the second processing unit detects the monitoring frame missing condition.

    摘要： An in-vehicle network system includes a plurality of relay devices that is connected to control devices of a vehicle, and communicates with each other and is configured such that each of a plurality of request devices that transmits a response request to the control device is connected to any one of the relay devices, a storage unit that stores a priority of the request devices, a master setter that sets, as the master, the relay device to which the request device having the highest priority has been connected among the relay devices to which any one of the request devices has been connected, and an arbitrator that performs arbitration to prioritize a response request from the request device having the highest priority when the response requests are transmitted from at least two of the request devices when the relay device in which the arbitrator is included is the master.
