<P>PROBLEM TO BE SOLVED: To provide an abnormality detection method and an abnormality detection device for speed detection means and vibration detection means that have improved abnormality detection precision. <P>SOLUTION: The abnormality detection method for speed detection means and vibration detection means for a railroad vehicle is configured to determine abnormality when at least one of a state in which a travel speed that the travel speed detection means detects is equal to or larger than a first threshold and vibration that the vibration detection means detects is less than a second threshold and a state in which the travel speed that the travel speed detection means detects is less than a third threshold and the vibration that the vibration detection means detects is equal to or larger than a fourth threshold, continues for a predetermined period or longer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
