<p><P>PROBLEM TO BE SOLVED: To provide a communication network in which waveform distortion occurring between two electronic control units connected to a transmission path or to a branch path is eliminated with a simple structure. <P>SOLUTION: The communication network 10 includes an ECU 14a (first electronic control unit); an ECU 14b (second electronic control unit); a bus (transmission path) 16 connecting the ECUs; and an ECU 14c (third electronic control unit) that communicates with at least one of the ECUs 14a, 14b via a branch path 20 branching from the bus. Each of the ECUs 14a, 14b is terminated by a terminal circuit that is in accordance with the characteristic impedance of the bus 16. At least one bypass circuit 24 is connected to the branch path 20, and signal transfer times are made different between the branch path 20 and the bypass circuit 24. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
