When chaufeur hopes to use keyfob 2 to be used to remove automobile burglar, before he can make keyfob 2 closely rest on the transmitter coil 10 that connects with self-propelled vehicle side control equipment (for example at the most 10 centimetres).Transmitter coil 10 for example is arranged near and/or the ELV assembly of startup/parking keyer.Between self-propelled vehicle side control equipment 1 and keyfob 2, initiate radio communication then.ECU 8 sends prearranged signals through aerial coil 10 through the LF base station 21 that interface 26 indications have full bridge driver 22 in the LF frequency band.This signal is applied on the coil mechanism 4 of keyfob 2, wherein, according to the spatial orientation of keyfob 2, said three coil output intensity different received signals.The reception signal of control unit 3 receiving coil mechanisms 4, and utilize microcontroller 16 that it is forwarded to vehicle anti-theft control device 18.At this, it is the interrogation signal about automobile burglar that control unit 3 identifies this.In addition three coils of control setup 3 magnetic test coil mechanisms 4 which/which coil received the signal by aerial coil 10 emission with maximum received field strength.Store corresponding information by microcontroller.Microcontroller 16 combines vehicle anti-theft control device 18 and code device 19 to generate acknowledge signal then, and this acknowledge signal should pass back to self-propelled vehicle side control equipment 1.This signal comprises the code of identifying keyfob 2, should make control convenience remove automobile burglar then or release turns to locking to the identification of this code.Handshaking between the aerial coil 10 of self-propelled vehicle side control equipment 1 and the coil mechanism 4 of keyfob 2 in the LF frequency band is through double-head arrow 13 expressions.Control unit 3 not only forms acknowledge signal, it also determine this signal should through in three coils of coil mechanism 4 which/which coil is back to control convenience.At this, the departure point of control logic is, supposes that keyfob 2 does not have the occurrence positions change or has only slight shift in position in the time period very short between this signal of reception and plan emission acknowledge signal.Based on this reason, control unit 3 decision acknowledge signals are through receive that coil emission of said reception signal before with maximum received field strength.The transmission signal that can guarantee many as far as possible shares thus also arrives at aerial coil 10.Led once more LF base station 21 and signal content of the signal that is received by aerial coil 10 is forwarded to ECU 8 through GIO interface 26, these ECU 8 these signals of assessment, and blind forwarding and is removed automobile burglar thus to locking when code is correct.
Handle and receive signal, generate acknowledge signal and launch the necessary energy of acknowledge signal and can obtain from battery 6 through the selected coil of coil mechanism 4.If as far as this this battery too a little less than, then can be provided with like this, make keyfob 2 comprise another accumulator, particularly cond, this accumulator is through charging at the energy that when coil mechanism 4 transmits signals, is transmitted by aerial coil 10.In order to utilize these energy as much as possible, the energy of whole three receiving coils of coil mechanism 4 all is used to accumulator or charge of a capacitor.Show that LED 7 for example is utilized for operating personal and shows when received enough energy, thereby can introduce the necessary step of emission acknowledge signal.For this reason operating personal with keyfob rest on aerial coil 10 near.In case LED 7 is switched on, the user just knows that he can remove automobile burglar and initiate the startup process.So he for example operates the start button that connects with self-propelled vehicle side control equipment 1.Above-mentioned communication takes place in the LF frequency band then.
What have advantage in addition is that the coil mechanism 4 with coil directed on three direction in spaces can be used to the keyless or passive entering system through improvement.When the chaufeur that carries keyfob 2 was positioned at vehicle exterior, this passive entering function (passive entry) was initiated through wake-up signal usually, and this wake-up signal is by the aerial coil emission that connects with self-propelled vehicle side control equipment 1.In traditional keyfob of having only a receiving coil that for this reason is provided with, the receiving intensity when receiving wake-up signal not only depends on the distance between aerial coil and the keyfob, but also depends on the random orientation of keyfob.Therefore in the traditional key remote controller, can not how far have apart from aerial coil based on the intensity estimation signal keyfob that receives.In keyfob 2 according to the present invention, can be by deriving the intermediate value (or total value) that allows distance between estimation self-propelled vehicle side aerial coil and the keyfob 2 in three signal receiving strengths of three coils of coil mechanism 4.For this purpose, 3D is set in control unit 3 wakes receptor 20 up, this 3D wakes receptor 20 up and not only is used to receive the wake-up signal that is sent by self-propelled vehicle side control equipment, but also allows the distance between estimation and the self-propelled vehicle.By means of this possibility, can improve the safety of entering.Therefore, for example have only when in the keyfob 2 assessment of wake-up signal being drawn keyfob and be located immediately near the conclusion the self-propelled vehicle, just can carry out the dialogue that is used to obtain access authorization that causes by this wake-up signal.
In the embodiment shown in Fig. 1, the emitting antenna coil 10 and two other emitting antenna coil 11 and 12 that are used for automobile burglar also are used to not have key or passive start-up system.As stated, aerial coil 10 is located immediately near the start button.Said two other aerial coil 11 and 12 is arranged in the proper site in the self-propelled vehicle, thereby can the reception signal strength of these keyfob 2 sides, obtain from the signal by three aerial coils 10,11 and 12 sequential firing about keyfob 2 at that time conclusion in stop place in motor-vehicle inside space.Here can prove also that the coil mechanism 4 that has on three direction in spaces directed coil has preceence because this coil mechanism 4 allow not rely on keyfob in the space each directionally estimate distance from keyfob to each aerial coil 10,11 and 12.The distance by 2 to three aerial coils 10,11 of keyfob and 12 based on estimation can confirm to stop the place.If keyfob 2 is positioned at the predetermined space of interior of motor vehicles, for example in the space above operating seat, then discharge start-up system, i.e. start the engine.Otherwise prevention engine starting.
