Title:
TRAVEL SPEED/POSITION DETECTION METHOD FOR RAILWAY VEHICLE
Document Type and Number:
Japanese Patent JP2016130675
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a travel speed/position detection method for a vehicle capable of accurately detecting a travel speed and a travel position of a vehicle in an unattended manner without using GPS data nor rotational pulse data on wheels.SOLUTION: A travel speed/position detection method comprises: a first step of finding a track gradient γ in an operation route in advance prior to various measurements of vibration, noise, etc.; and a second step of measuring front/rear-directional acceleration α of a vehicle by an acceleration sensor mounted on the vehicle in the various measurements, and finding travel acceleration P of the vehicle for placing the vehicle in travel-directional motion from the measured acceleration and the track gradient γ found in advance. In the second step, the front/rear-directional acceleration α of the vehicle is corrected based upon the track gradient γ at the measurement point so as to remove an influence of the track gradient γ at the measurement point on the front/rear-directional acceleration α of the vehicle from the measured front/rear-directional acceleration α of the vehicle.SELECTED DRAWING: Figure 4
