<p>PURPOSE:To prevent a delay of control by revising a data transmission reception period between control units being components of the multiplex transmitter in response to an opposite control unit and a state of vehicles at that time so as to set a signal density on a transmission line to a proper state thereby implementing the communication efficiently. CONSTITUTION:The transmission of information among plural control units A-F is implemented periodically in the multiplex transmitter in which the plural control units A-F connected decentralizingly to a common multiplex transmission line 1 transmit and receive the information and the transmission period of the information is changed in response to a control unit of a communication opposite party. Moreover, the information among the plural control units A-F is transmitted periodically and the transmission period of the information is varied in response to the operating state of the plural control units A-F being the communication opposite parties and vehicles.</p> |
