Patent ID: 8560197

Claim:
A moving vehicle system for making an in-position determination when a moving vehicle enters an in-position range, the moving vehicle system comprising: a sensor arranged to determine a position, a velocity, and an acceleration of the moving vehicle; and a computation unit arranged to determine whether a stop position of the moving vehicle will be within the in-position range or not, based on the determined position, velocity, and acceleration; wherein the computation unit is arranged to determine time series velocity data {vi} from time series position data {Pi} and to determine time series acceleration data {ai} from the determined time series velocity data {vi}, where i denotes a time series suffix and where Pi, vi, and ai respectively indicate a current position, a current velocity, and a current acceleration of the moving vehicle; and the computation unit is arranged to estimate an upper limit of the stop position as a distance of −vi 2 /ai from a current position.
