Method and device for determining the location of a vehicle

摘要

A method for determining the location of a vehicle using a GPS receiver (9) and a predefinable coordinate system, in particular a city map, a map, a nautical chart or the like, comprises the following method steps: determination of the GPS coordinates by means of a GPS receiver or some other suitable method, for example Gallileo, beacon, etc., projection of the determined coordinates onto the coordinate system and correction of the GPS coordinates or the projected coordinates in the sense of compound navigation. A corresponding device is specified.

1. A method for determining the location of a vehicle using a GPS receiver and a predefinable coordinate system, especially a city map, a map, a nautical chart or the like, said method comprising:
determining GPS coordinates by means of the GPS receiver or another appropriate method, for example, Galileo, beacon, etc.; projecting the determined GPS coordinates onto the coordinate system; and correcting the projected coordinates by use of dead reckoning with consideration of the direction change and speed of the vehicle in the coordinate system,
wherein correcting the coordinates in the coordinate system occurs with consideration of previously determined or projected coordinates by means of the history,wherein the path of the vehicle with an unsteady path trend is smoothed or corrected according to the history, andwherein the correction of the coordinates in the coordinate system occurs with consideration of the quality of the GPS reception in such a way that the scope of the correction and expense involved with the correction is made dependent on the number of received satellites.
