Abstract (en)
An inspection apparatus (500) gives a measured value of a forward-and-backward-direction force and an actual value of a transformation variable to a Kalman filter, to derive state variables. At this time, a preset fixed value (0 (zero), for example) is used as values to be normally given as measured values of observation variables (accelerations of a vehicle body (11), bogies (12a, 12b), and wheel sets (13a to 13d) in a right and left direction) when performing data assimilation.
