| 摘要 |
The invention relates to an electronic control circuit for a motor car-door locking system. Said circuit comprises: a printed circuit board (2), on which at least specific control circuit components are mounted; a control unit (20) comprising an induction coil (3), which forwards a data request to an external contactless data carrier and triggers the unlocking of the motor car-door locking system, if a valid response is received from the data carrier; a proximity sensor (5) comprising at least one proximity electrode in order to trigger the forwarding of the data request, if a person approaches said electrode; a capacitive contact sensor (22), which senses the contact between the hand of a person wishing to gain access and the external door handle (7), said sensor comprising two capacitive electrodes, which are mounted opposite each other on both sides of the printed circuit board. The proximity sensor electrodes, the contact sensor and the induction coil (3) are housed in the external door handle of a motor car. |
