<p><P>PROBLEM TO BE SOLVED: To start a node in a sleep mode if needed without increasing power consumption during a sleep mode in a communication system having a wake-up/sleep function. <P>SOLUTION: A transceiver 12 of ECU 10 in a sleep mode changes a level of a wake-up signal WU to an active level when it is detected that a frame including an error flag (6-bit or more continuous dominant) is transmitted to a communication path LN in an error flag detection circuit 22 and the feature amount (number of attention edges) extracted from a bit pattern set to a specification pattern area (before the error flag) of the frame coincides with the start amount allocated to the own ECU 10 beforehand (i.e., when both of an error flag detection signal Def and a coincidence detection signal Did are in the active level) in a feature amount detection circuit 23. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
