Title:
INSPECTION SYSTEM, INSPECTING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/121943
Kind Code:
A1
Abstract:
An inspecting device (500) derives a state variable by applying a measured value of a front-rear direction force, and an actual value of a conversion variable, to a Kalman filter. At this time, a fixed value (for example 0 (zero)), set in advance as a value originally applied as a measured value of an observed variable (acceleration in left-right direction of vehicle body (11), bogies (12a, 12b), and wheel sets (13a to 13d)) is used during data assimilation.
