Embodiment Construction

[0025] Hereinafter, the present invention will be described in more detail with reference to the drawings and specific embodiments.

[0026] Such as figure 1 As shown, an automotive smart card positioning system includes an electronic control unit (ECU, Electronic Control Unit) 1, a transmitting antenna 2 and a smart card 3. The transmitting antenna 2 is arranged in the car compartment, is electrically connected to the electronic control unit 1 and transmits wireless low-frequency signals according to its instructions; the smart card 3 is matched with the electronic control unit 1, the transmitting antenna 2, and the smart card 3 and the transmitting antenna 2 Matching means that the smart card 3 can receive the signal transmitted by the transmitting antenna 2. The smart card 3 matching with the electronic control unit 1 means that the electronic control unit can receive the signal transmitted by the smart card, and the smart card 3 receives the signal transmitted by the transmitt...

Abstract

The invention relates to an automobile intelligent card positioning system, which is characterized by comprising an emission antenna, an intelligent card and an electronic control unit; the emission antenna is arranged in an automobile carriage; the emission antenna is electrically connected with the electronic control unit and used for transmitting wireless low-frequency signal according to the command; the intelligent card is matched with the emission antenna and the electronic control unit; the intelligent card receives the wireless low-frequency signal and detects the magnetic-field strength of the wireless low-frequency signal, and transmits the detection result to the electronic control unit through the wireless high-frequency signal; the electronic control unit compares the magnetic-field strength data in the received wireless high-frequency signal with the previously stored reference data so as to determine the position of the intelligent card. The automobile intelligent card positioning system has the function of accurately positioning the intelligent card, thereby realizing the passive entrance and starting of the automobile and bringing much convenience to the driver.

Description

Technical field [0001] The invention relates to a positioning system, in particular to an automobile smart card positioning system. Background technique [0002] At present, the current car access control system usually used is the car remote access control system (RKE, Remote Keyless Entry). In recent years, a new type of car access control system-car keyless entry system (PKE, Passive Keyless Entry)-is Quietly appearing, the car keyless access control system is developed on the basis of the car remote access control system. As a new generation of car anti-theft technology, it is gradually developing and expanding. It is now being equipped in high-end brand cars, equipped with keyless access control and ignition authentication system The car has gradually become a symbol of the status of the driver. When the driver enters the designated area with the smart card, the car keyless access control system can recognize the smart card, and if it is judged to be a legally authorized sm...
