A method, apparatus and system for determining a position of a vehicle

The invention provides a method, apparatus and system for determining a position of a vehicle. The method comprises the steps of: measuring (S01) at least a first magnetic field strength of a magnetic field at a respective first position (Ai) by a first magnetic field sensor (11) mounted on a vehicle (1) is disposed; Measuring (S02) is arranged at least a second magnetic field strength of the magnetic field at a respective second position (Bi) by means of a second magnetic field sensor (12) supported by the first magnetic field sensor (11) spaced on the vehicle (1); Determining (S03) of position data of the vehicle (1) at least by comparing data, which are based on the measured first and second magnetic field strengths, with a predetermined magnetic field information of the magnetic field; and outputting (S04) a signal based on the position data.
