PROBLEM TO BE SOLVED: To provide a collision detection device and a collision detection method capable of improving precision for judging collision of a railway vehicle.SOLUTION: Upon the opening and closing of a door of a railway vehicle of a heading vehicle 101, an intermediate vehicle 102 or the like, only acceleration caused by an instantaneous shock occurs. On the other hand, upon the collision of the railway vehicle, acceleration when a structure of the railway vehicle becomes depressed or is damaged is caused in addition to the acceleration of instantaneous shock. Therefore, according to a collision detection device 110a, a collision judgement part 118 of the collision detection device 110a judges the collision of the railway vehicle based on a plurality of pieces of sampling data in the elapse of time of the acceleration of the railway vehicle. Thereby, the precision for judging collision of the railway vehicle can be improved.SELECTED DRAWING: Figure 2 |
