摘要： An in-vehicle network system deployed in a vehicle includes a plurality of first nodes configured to perform an operation relevant to a first function in the vehicle, a second node configured to perform an operation relevant to a second function different from the first function in the vehicle; and a relay device configured to relay communication between the first nodes and the second node. The relay device is configured to start relay of communication between the first nodes earlier than the relay of communication between the first node and the second node at a time of startup.

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.

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： An in-vehicle network system includes a plurality of controllers; a plurality of communication lines connected to the controllers, respectively, a relay device connected to the controllers via the communication lines, and a retention determiner configured to determine whether retention of data occurs in the relay device. The relay device is configured to relay data between the communication lines, and configured to preferentially relay data having a priority equal to or higher than a predetermined priority such that the data reaches the controller that is a transmission destination among the controllers within a first predetermined time when the retention determiner determines that the retention occurs.
