METHOD, DEVICE AND SYSTEM FOR DETERMINING A POSITION OF A VEHICLE

摘要

The invention relates to a method, to a device, and to a system for determining a position of a vehicle. The method comprises the method steps: Measuring (S01) at least one first magnetic field strength of a magnetic field at one each first position (A-i) by means of a first magnetic field sensor (11) arranged on a vehicle (1); measuring (S02) at least one second magnetic field strength of the magnetic field at one each second position (B-i) by means of a second magnetic field sensor (12) arranged on the vehicle (1) at a distance from the first magnetic field sensor (11); determining (S03) position data of the vehicle (1) at least by comparing data, which are based on the measured first and second magnetic field strengths, to a predetermined magnetic field data of the magnetic field; and outputting (S04) a signal based on said position data.

1. A method for ascertaining a position of a motor vehicle, the method comprising:
measuring at least one first magnetic field strength of a magnetic field at a respective first position by means of a first magnetic field sensor that is arranged on a vehicle; measuring at least one second magnetic field strength of the magnetic field at a respective second position by means of a second magnetic field sensor that is arranged on the vehicle at a distance from the first magnetic field sensor; ascertaining position data for the vehicle at least by comparing data that are based on the measured first and second magnetic field strengths with a predetermined magnetic field information item of the magnetic field; and outputting a signal on the basis of the position data.
