    摘要： A message is efficiently relayed in a cut-through mode to a communication line of the transmission destination of a transmission rate higher than that of the communication line of the recipient while preventing the state that there is no data to be transmitted. A vehicle-mounted relay connection unit is used to relay messages received through first CAN communication lines to a second CAN communication line of a transmission rate higher than that of the first transmission lines in a cut-though mode. A relaying section measures the time difference between the time when the reception of the control field of a message among the messages simultaneously received through the first CAN communication lines is completed earliest and the time when the reception of the control field of another message is completed, determines the transmission waiting time from the completion of the reception of the control field of each message, and first relays the message such that the sum of the transmission waiting time and the time difference of the reception completion is small to the second CAN communication line.

    摘要： A vehicle-mounted Local Area Network (LAN) system includes vehicle-mounted LANs in each of which an electronic control unit is connected to a communication line to send and receive messages. The LAN system also includes a relay connection unit that relays the messages between the vehicle-mounted LANs. Each electronic control unit has a reception port for transmitting a reception confirmation signal to the relay connection unit in response to a received message. The relay connection unit has a relay management device that determines, based on the presence or absence of the reception confirmation signal responsive to the message relayed to each of the vehicle-mounted LANs, whether or not a relay is required, and that then updates relay processing information stored in a storage device.

    摘要： An on-vehicle communication system has a plurality of buses relay-connected through a relay connection unit, each of the buses having at least one ECU connected thereto. In the vehicle communication system, a basic routing table that specifies a relay point for transmitting from the relay connection unit to the ECU is stored in a ROM and a transmission list report message about message IDs is transmitted. The ECU receives the transmission list report message and sends back a transmission request message about a message ID, which is not included in the transmission list report message but should be received, to the relay connection unit. The transmission request message is received by a table creation unit in the relay connection unit. The table creation unit creates a new additional routing table indicating a correspondence relationship between an ID requested by the transmission request message and a transmission destination and being stored in a RAM.

    摘要： A Relay connection unit connects networks connected to ECUs via multiple communication lines and relays signals transmitted/received between the ECUs belonging to the different networks. The relay connection unit comprises a recording part that records the relationship between ECUs that currently transmit/receive signals to/from each other; a buffer part that records transmission completion times at which the relay connection unit transmits signals received from ECUs to the networks to which other ECUs of relay destination belong; and a communication abnormality determining part that determine a time difference (T) between the transmission completion time corresponding to a network, for which the signal transmission has been completed the earliest, and each of the transmission completion times corresponding to the other networks for which signal transmissions have been completed and that determines that the signal transmission to a network for which the corresponding time difference is equal to or greater than a predetermined time is a communication delay.

    摘要： It is possible to reduce the memory capacity of a buffer of relay connection unit and reduce the time required for deciding a message to be transmitted. A relay connection unit is arranged between bushes to which electronic control units are connected and relays a message transmitted and received between the electronic control units belonging to different bushes. The relay connection unit includes: a buffer which temporarily stores message in the order to receptions; a storage unit which stores the priority set for each of the message; and a processing unit which extracts N message in the order of the receptions from the buffer, reads the priorities of the respective messages extracted from the storage unit, compares the priorities of the N messages, and transmits the message having the highest priority.
