Abstract (en)
[origin: WO03071068A1] The invention relates to an electronic control circuit for a motor car-door locking system. Said circuit comprises: a control unit (20) with an induction coil (3) for relaying a data request to an external contactless data carrier and for triggering the unlocking of the motor car-door locking system, if a valid response has been received from the data carrier; a proximity sensor comprising at least one proximity electrode (5) for triggering the relaying of the data request, if a person approaches the proximity sensor. The induction coil (3) comprises a ferrite core (35) and a wire (33) that is wound around said core and is housed in a cavity (72) of a handle (7) of the motor car-door locking system. At least one part (31) of the wire winding is connected mechanically to the surface of the ferrite core, in such a way that the coil can be further processed as an SMD component.
