SYSTEM FOR ANALYZING SHAKING OF TRAVELING VEHICLE AND METHOD FOR ANALYZING SHAKING OF TRAVELING VEHICLE

摘要

A three-axis acceleration sensor for detecting vibratory acceleration in the forward-backward direction, left-right direction, and up-down direction of a vehicle traveling on a track, a GPS antenna, and a GPS receiver are placed on the vehicle. Positional information of the vehicle is corrected based on positional information acquired by a signal that the GPS receiver receives by the GPS antenna and on acceleration in the forward-backward direction of the vehicle.
