A method for detecting obstacles in front of rail vehicles

摘要

A method for detecting obstacles (h) in front of rail vehicles (fz), which is a certain distance (str) and wherein an on-board computer (br) for storing the route data is provided, wherein as route data coordinates of centrally between the rails (sch1 and sch2) in certain intervals of points that lie (sp1, sp2, sp3, sp4) are stored, whereby the stored points (sp1, sp2, sp3, sp4) and between these interpolated points (p) of a vehicle sensor (s) by means of the track curvature and the distance (d) dependent on the pivoting of the sensor signal by an angle (α) with respect to the instantaneous direction of travel (fr) are sighted, wherein the opening angle (w) of the vehicle sensor (s) received signals, in the center of which the sighted point (sp1, sp2, sp3, sp4; p) lies, as a function of the distance (d) and from the pivot angle (α) is changed in such a way that only the distances of interest space (sr) is detected, and wherein the points (p) between the stored points (sp1, sp2, sp3, sp4) by means of interpolation on the straight line or be determined on parabolas.
