Abstract:
A passive keyless entry (PKE) system is disclosed. The PKE includes an in-vehicle apparatus. The in-vehicle apparatus includes a control unit that is configured to measure magnetic field and compute at least one angle between two projections of the magnetic field. When the measured angle is lower than a threshold value, an authorization signal is prevented.

Claim (Index 1):
A passive keyless entry system including an in-vehicle apparatus installable on a vehicle and a portable apparatus, the in-vehicle apparatus including:\n a plurality of antennas for generating a plurality of respective magnetic fields, an in-vehicle receiver for communicating with a portable transmitter of the portable apparatus, an in-vehicle control unit for controlling the plurality of antennas and for generating an authorization signal based on information received from the portable apparatus, the portable apparatus including:\n a receiving antenna having three mutually orthogonal coils, \n a portable transmitter for communicating with the in-vehicle receiver, \n a portable control unit for controlling the receiving antenna and the portable transmitter, \n the portable apparatus\\being configured for measuring at least two projection vectors\\of the magnetic fields\\, \n the in-vehicle control unit\\or the portable control unit\\being configured for computing at least one computed angle\\between two projection vectors\\the magnetic fields\\, \n the in-vehicle control unit\\or the portable control unit\\being configured for comparing the at least one computed angle\\with an angular threshold value, \n the in-vehicle control unit being configured for preventing the authorization signal when all the computed angles are lower than angular threshold value.
