摘要： In a network system which sequentially passes a right to transmit in the form of a token and includes a plurality of data processors, at least one of the plurality of data processors is set so as to be able, during each possession of the token, to send messages in greater number than those transmitted by each of the remaining data processors by at least one. The data processor that is allowed to send many messages consecutively sends messages by inserting, into a token address field included in a message format, its own address during transmission. In the case of a server/client network, a server is set so as to consecutively send a number of messages at a time, while in possession of the token.

摘要： A data transmission system for automotive vehicles in which messages are transmitted by circulating a transmission right signal among a plurality of electronic control units, by a token passing method. Each of the electronic control units judges that the right to transmit a message to the network bus has been acquired when it is determined that the transmission right signal has not been circulated for a predetermined time period, and at the same time an idle state of the network bus has been detected. If a collision of the transmitted message with any other message is detected, the above process is repeated after the lapse of a waiting time period specific to the electronic control unit which judged that the right to transmit a message had been acquired.
