Be labeled as among the figure: 1, key; 2, repeater; 3, ignition lock; 4, antitheft coil; 5, anti-theft controller; 6, Engine ECU; 7, storage battery; 8, diagnostic tester.

The specific embodiment

Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail embodiment:

Shown in accompanying

drawing

1,2, the utility model is the key of a kind of later-model band remote control and electronic anti-theft function, comprise key 1, ignition lock 3, Engine ECU 6, the key of described later-model band remote control and electronic anti-theft function also comprises repeater 2, antitheft coil 4, anti-theft controller 5, described repeater 2 is arranged on the key 1, antitheft coil 4 is installed on the ignition lock 3, and anti-theft controller 5 is connected with Engine ECU 6 with antitheft coil 4 respectively.

Described antitheft coil 4 is connected with anti-theft controller 5 by wire harness, antitheft coil 4 be set to can be between anti-theft controller 5 and repeater 2 structure of signal.

Described anti-theft controller 5 is an ECU electronic control unit that comprises microprocessor and semiconductor element.

Described Engine ECU 6 is set to accept the structure of the cognizance code that sends from key 1.

The effective information transmission distance of described repeater 2 is 2-3cm farthest.

Every a repeater is all arranged in the automobile key, repeater is a passive device.These parts during system works, and antitheft coil is finished jointly and anti-theft controller between encrypting and authenticating.The effective information transmission distance of repeater is 2-3cm farthest.

Antitheft coil 4 of the present utility model is installed on the ignition lock 3 of automobile, links to each other with anti-theft controller 5 by wire harness.Antitheft coil 4 is born signal and transmission of energy task between anti-theft controller 5 and the repeater 2 as the load of anti-theft controller 5.

Anti-theft controller 5 is ECU electronic control unit that comprise microprocessor and multiple semiconductor components and devices, is the core component of whole anti-theft system.When automobile dispatched from the factory, the antitheft cognizance code that anti-theft controller 5 is equipped with good this car for key 1 was so the antitheft control routine of each automobile is different.When opening ignition lock 3 with key 1, anti-theft controller 5 is given repeater 2 by antitheft coil 4 with electrical energy transfer.After repeater 2 is energized, launch the cognizance code of the key 1 of this car immediately.Antitheft then coil 4 sends back anti-theft controller 5 with the cognizance code of key 1.Anti-theft controller 5 is accepted cognizance code and Engine ECU communication, and ECU differentiates whether this key 1 is the legal key 1 of this car, and automotive ignition and fuel-feed system connection maybe will not be connected.
