Method of determining and presetting the desired speed value in rail bound vehicles

In a method of determining and presetting the desired speed value for rail bound vehicles, the route travelled from the starting location is determined by integrating the recorded actual speed of the vehicle. The permissible maximum speed for route sections, and the distance of points on the route from the starting location are stored in a route database 4. The longitudes and latitudes relating to points on the route, determined by surveying the route, are stored in a further database 3. At time intervals, the position of the vehicle is determined by means of satellite navigation 7. Then, using these recorded longitudes and latitudes relating to a position, the surveyed longitudes and latitudes relating to individual points on the route, and the distance between adjacent cartographic longitudes and latitudes, a search loop with a minimum-value algorithm is used to determine the distance between the position and the nearest stored surveyed point on the route. In this way, the integration ...
