<p><P>PROBLEM TO BE SOLVED: To provide a technology of reducing a "deviation" amount of a transmission/reception reference without a circuit correcting a "deviation" of a reference timing (transmission/reception reference) of data transmission/reception in a communication system where a clock signal is transmitted from a certain communication device and a communication device having received the clock signal transmits/receives data referring to the received clock signal. <P>SOLUTION: A communication ECU 10 which is a master device sends a clock signal to a clock communication line 5 so that the communication ECUs 10 and 40 can synchronize with each other when sending and receiving data. The communication ECUs 10 and 40 then receive the clock signal through the clock communication line 5. The ECUs 10 and 40 use the received clock signal as a transmission/reception reference which is a reference timing at the time of data transmission/reception, and send or receive data to/from data communication lines 6 and 7 other than the clock communication line 5. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
