REAL TIME CONTROL NETWORK SYSTEM

摘要

Provided is an on-vehicle network which can improve the network use efficiency and reduce the controller processor overhead even when the same communication cycle as the frame cannot be set in the filtering condition of a communication control device. A reference signal transmission controller is arranged in a network so as to generate and transmit a reference signal in accordance with the communication cycle. A reference signal reception controller receives the reference signal and compares the reference signals to a predetermined filtering condition table. If the signal is matched with the table, the controller executes a data reception process and a data transmission process.
