Accompanying drawing explanation
The present invention is described in detail with reference to accompanying drawing below by preferred form of implementation according to the present invention.Wherein:
Fig. 1 shows according to the vehicle with zones of different (looking for the radio key be associated with vehicle) of the present invention wherein,
Fig. 2 diagrammatically illustrates the vehicle according to the invention being with good grounds device of the present invention.
Detailed description of the invention
According to the manipulation of the bonnet of vehicle according to the invention 10, the present invention should be shown by means of Fig. 1.
In order to close the bonnet that this is opened, the chaufeur (it carries with the radio key 1 be associated with vehicle 10) of vehicle 10 handles button at bonnet place or button (not shown).The distance of radio key 1 and vehicle 10 is directly determined after this manipulation of button.To this, the intensity of the electric current flowing through the first radio antenna of vehicle 10 is adjusted to the sphere of action only overlay area Z1 (region of boot compartment) and region Z2 making the first radio antenna.This sphere of action also should cover boot compartment, because such as also may be arranged in the pocket of boot compartment in the moment radio key 1 of operating buttons.
First radio antenna is launched such as, with the LF signal of the form of amplitude modulation (" low frequency ", 125kHz or 21kHz).When radio key 1 receives the such LF signal with the first radio antenna of enough high field intensities (such as >62dBuV/m), radio key 1 itself sends and illustrates that radio key 1 have received the information of the LF signal with enough high field intensities.At this, radio key 1 especially works with UHF frequency (such as European 434MHz or for north America region 315MHz).In order to receive the information of radio key 1 in vehicle 10, usually there is the second radio antenna coordinated with the transmission frequency of radio key 1 there.
Very first time interval (such as 3s) period started with operating buttons, the intensity of current by the first radio antenna is adjusted to the radio key 1 making to exist in Z1 and Z2 of region and receives LF signal with enough high field intensities.Only when the interim very first time radio key 1 the information received with the second radio antenna illustrate that radio key 1 have received LF signal (namely radio key 1 is positioned at region Z1 and Z2) with enough high field intensities time, just do not interrupt the manipulation of closure member.In other words, when have received the information with the LF signal of too little field intensity in the explanation radio key that the interim very first time receives radio key 1, or when the LF signal for the first radio antenna send radio key 1 do not receive information time, do not handle bonnet or closure member.If be such situation (that is radio key is neither arranged in region Z1 and is also arranged in region Z2), be implemented to optics and/or the acoustic feedback at operating personal or chaufeur place, to inform that its bonnet is not opened or closed.
(that is this manipulation is not yet interrupted) that if the manipulation of closure member still activates after the very first time, interval was terminated, during the second time gap so started at the end of very first time interval, the intensity flowing through the electric current of the first radio antenna is alternately adjusted in the first intensity and the second intensity.At this, the first intensity is corresponding to the sphere of action of overlay area Z1 and region Z2, and the second intensity is corresponding to the sphere of action of overlay area Z1 to Z3.Only when at this moment radio key 1 is not reported with during the first intensity energising at the first radio antenna with the LF signal of enough high field intensities to report during the second intensity energising that it have received at the first radio antenna, the manipulation of closure member just keeps activating (otherwise it is interrupted, and this is correspondingly informed to chaufeur again).
In other words, radio key 1 must be continued in Z1 and Z2 of region in the interim very first time, and it must be arranged in the 3rd region Z3 at least one times during the second time gap, keeps activating and not being interrupted with the manipulation of this closure member.Therefore ensure on the one hand the operation most probable of button to be operated by the chaufeur carrying with radio key and ensure that radio key 1 (with therefore chaufeur) is after a first time interval away from vehicle 10 on the one hand.
At this, the present invention can be designed such that chaufeur is back to the interruption that vehicle 10 causes the manipulation of closure member.At this, returning of chaufeur can detect as follows.
If the radio antenna of certain moment first in the second time gap do not cause the information in the front of radio key 1 (that is radio key is neither arranged in region Z1 and is not also arranged in region Z2) with the energising of the first intensity of current and if to cause the information in the front of radio key 1 (that is radio key 1 be in region Z1 or at region Z2) with the energising of the first intensity of current at moment first radio antenna afterwards, so radio key 1 (with therefore chaufeur) must move back to vehicle 10 again.
(utilize it to check whether radio key 1 moves to the Z3 of region from region Z2 according to the present invention) in a similar fashion, can check now whether radio key 1 moves to the Z4 of region from region Z3.Only when radio key 1 moves in the Z4 of this region, the manipulation of closure member keeps activating.
Finally, can check whether radio key 1 moves to the Z5 of region from region Z4 according to the present invention in a similar fashion.When (being that is not yet interrupted) that the detected and manipulation of closure member of radio key 1 (or rather outside the Z1 to Z4 of region) in the Z5 of region still activated in this moment, open or close closure member, because outside the carrier of radio key 1 is in closure member safety distance (such as outside the wobble area of bonnet).
At this, the raising of the energising of the first radio antenna can be matched with key carrier or with the leg speed of chaufeur having radio key.To this, once detect that radio key 1 moves to the Z3 of region from region Z2, can start to check whether radio key 1 moves to the Z4 of region from region Z3.In a similar fashion, once detect that radio key 1 moves to the Z4 of region from region Z3, can start to check whether radio key 1 moves to the Z3 of region from region Z4.
Should perform and check whether radio key 1 is in (and therefore outside the Z1 to Z4 of region) within the Z5 of region, to detect radio key 1 entering again situation in the Z4 of region entering with radio key 1 the 3rd period time period (such as 2s) started in the Z5 of region.In this case, opening or closing of closure member is stopped.
Diagrammatically illustrate vehicle according to the invention 10 in fig. 2, it comprises four car doors 6, bonnet 5 and according to device 20 of the present invention.Device 20 according to the present invention comprises control part 2, LF antenna 3 and UHF antenna 4 in it, and both and control part 2 are linked.At this, device 20 is designed so that it can on the one hand be determined minor increment between LF antenna 3 and the radio key 1 being associated with vehicle 10 in mode according to the present invention and handle car door 6 or bonnet 5 in mode according to the present invention on the other hand.
