Motor vehicle e.g. car, influencing earth`s magnetic field detecting method for use in multistory car park, involves evaluating electrical output signal to determine changeable magnetic field vector in determined direction as record
The method involves producing an electrical output signal by a sensor arrangement (7), for each of the detected directions of earth`s magnetic field, which locally influences a vehicle. An evaluation unit (8) evaluates the combined output signals to determine a magnetic field vector in the determined direction as a data record, where the vector is changeable by the vehicle. The record is suitable for further evaluation of the output signal. Independent claims are also included for the following: (1) an arrangement for detecting earth`s magnetic field locally influencing a vehicle (2) a use of the arrangement for detecting earth`s magnetic field locally influencing a vehicle for monitoring the allocation of parking areas in a multi-story car park.
