<P>PROBLEM TO BE SOLVED: To enable identifying an initiation frame to a self-node in a communication system capable of independently waking up a node in a sleep mode without increasing power consumption of the node in the sleep mode. <P>SOLUTION: An initiation frame detector 17 monitors a communication channel LN via a comparator CP2 of a receiver 16, and recognizes a frame, as an initiation frame, in which a region length from the top of the frame to a point where dominants are successive in 2 bits (completion timing) is larger than an initiation length (changes an indiscriminate wake-up signal WA to an active level). Further, when a designation code represented by a decode data Ddc that is given by regarding, as a duty signal, a designation pattern set in a designation pattern region of the wakeup frame and decoding the designation pattern set, coincides with an allocation pattern allocated beforehand to a self ECU 10, the initiation frame detector 17 shifts to a normal mode (changes an individual wake-up signal WU to the active level). <P>COPYRIGHT: (C)2012,JPO&INPIT |
