<P>PROBLEM TO BE SOLVED: To restrain coupled vibration of a train which is constituted by jointing a plurality of vehicles by a joint device having spring characteristics at low cost, and improving ride comfort of the train. <P>SOLUTION: Some motive power units having power units m2, m4, m5 among vehicles c1-c6 which constitute the train have a sensor a5 which detects motion in an advance direction. Power control devices i2, i4, i5 which control the power units m2, m4, m5 have oscillation samplers which sample frequency devices corresponding to the oscillation mode of the coupled vibration of the train from the output of the sensor a5, thus controlling the power units m2, m4, m5 so that the power controllers i2, i4, i5 may restrain the output of the oscillation sampling portions. <P>COPYRIGHT: (C)2008,JPO&INPIT |
