By EP 2070780 known a kind of methods, this method is controlled an only antenna with distinct transmit power.This antenna arrangement is in the side direction of central longitudinal axis, and depends on and will use which car door and control with distinct transmit power.
Summary of the invention
Technical matters to be solved by this invention is, a kind of method is provided, so that be the reliable control of access entitlements or rights of using, in vehicle, uses antenna still less.
According to the present invention, this technical matters is through a kind of method with claim 1 characteristic.
According to the present invention, a kind of method that is used to check to the rights of using of the requested function of motor vehicle is provided.
In case note the request of function, then control at least one antenna in the motor vehicle, so that under first emissive power, send first radio signal by the control device of vehicle side.The antenna transmission radio signal is in the space that limited by emissive power, and extend in the location about of antenna in this space.Coverage depends on the surrounding enviroment of power, antenna performance and antenna at this.But the power that needs can be to special vehicle not only through analog computation but also rule of thumb know.
First radio signal is received by the identifying information transmitter that moves, as long as this identifying information transmitter is in the coverage scope of the antenna in first emissive power.In form of implementation of the present invention, the identifying information transmitter receives signal and replys the answering machine motor-car with first radio.Before the replying of signal, can carry out content verification, and can depend on checking and send answer with the message of this signal encoding.The radio that receives the identifying information transmitter in vehicle side is replied.Antenna in motor vehicle is controlled to be used for sending second radio signal to the identifying information transmitter that moves with altered second emissive power, and this identifying information transmitter receives, analyzes in case of necessity and reply said signal again.The radio of identifying information transmitter is replied in vehicle side and is analyzed knowing rights of using, and depends on assessment or analyze open or forbid or open requested function.
According to the present invention, by the identifying information transmitter know the signal that is received signal intensity, change into signal strength values and the value of this signal strength values after as coding is delivered to the control device of vehicle side in radio replied.
Knowing of the intensity that transmits is known in wireless communication basically.For example receiving signal strength indicator (RSSI) is the yardstick that in wireless communication, is directed against the field intensity that is received.In this value, confirm the value of a no unit between 0 to 250, this value provides the signal intensity that is received.This RSSI value is delivered to the device of vehicle side by the identifying information transmitter.Because in vehicle side; The signal intensity of emission is known; And because the variation of the signal intensity when the radio signal of sending in succession, and because the arrival of the notice of identifying information transmitter (can receive said signal with which kind of intensity), so detailed assessment is possible.In the confidence level check, especially can improve the security of system, because can get rid of so-called relay site attack or the prolongation of radio distance.
The present invention has utilized the communication that has different field intensity in the inquiry circulation and to the feedback of the emissive porwer that receives in the identifying information transmitter.
Through under the distinct transmit power of the antenna of vehicle side to the repeatedly inquiry of identifying information transmitter; Can remedy many following shortcomings, compare said shortcoming with system and concerning the system that only has an antenna in other cases, exist with a plurality of antennas.With respect to the prior art of being mentioned, the present invention has utilized in query script and has controlled what antenna carried out with distinct transmit power.Just assess the identifying information transmitter to the repeatedly feedback of wake-up call, said wake-up call can be sent when change in signal strength.
Replying according to the present invention of identifying information transmitter do not need directly after receiving signal, to carry out.Or rather, also can in response packet, transmit a plurality of replying.In the latter case, the device of vehicle side was waited for a preset time section before the secondary signal with altered emissive power is stopped.
According to an example maneuvering engine start button.At first under first transmitted power, use the emission of wake-up signal, the emission meeting of this wake-up signal is by the record of identifying information transmitter with first signal intensity.Under second emissive power that has for example enlarged, the identifying information transmitter can receive and write down corresponding higher emissive power, and this can not be this situation under the situation that the radio distance prolongs.Postback, be taken into account about the information of the emissive power that receives by the identifying information transmitter to get into control more reliable so that make.Especially check, whether credible by the transmission signal contact of identifying information transmitter passback to predetermined transmission signal.The present invention advantageously utilizes the transmission of a plurality of signal intensities again in proof procedure.
In the general design proposal of said method, the identifying information transmitter can with an only radio reply a plurality of vehicle side write down transmit, for example after two that obtain vehicle transmit.In a said radio is replied, can comprise information about the signal intensity of two signals that receive.In an only message of identifying information transmitter, jointly transmit advantageous particularly, this is because because radio is still less replied and need be sent out, the energy reserve of identifying information sender side is protected.
In a kind of form of implementation of the present invention,, know emissive power immediately and pass back to vehicle to transmitting of identifying information transmitter record.Just in the replying of each radio signal, answer is delivered to vehicle.Individually receive in vehicle side then and reply, and jointly consider for assessment.When the transmission of the other signal with altered intensity depended on the reception of replying, this mode was favourable.
According to a kind of form of implementation of the present invention, antenna arrangement is acentric position in motor vehicle, wherein, non-centrally means that in this linguistic context antenna is especially arranged with respect to vertical symmetrical plane longitudinally with respect to the symmetrical plane of vehicle with staggering.
Verified in the checking flow process because have the identifying information transmitter of a plurality of different field intensity, so can infer the position of identifying information transmitter with respect to vehicle.For example be possible as follows, that is, by means of acentric position with first emissive power and with the scope of field strength distribution cover in the vehicle with car door before the zone, but do not cover away from the side on car door before the zone.At this, the field strength distribution scope obviously is not meant physically possible or unlimited field strength distribution, but considers technical field intensity relevant, that just can on the triggering limit of identifying information transmitter, can measure.
In second emission process, use second, bigger or littler emissive power to come further to define the location of identifying information transmitter.
Importantly, send a plurality of radio signals to the identifying information transmitter by method of the present invention by vehicle side.In the said radio signal at least two send with various signals intensity.But according to the present invention also is possible as follows; Promptly; Send a plurality of radio signals with first signal intensity, and send one or more secondary signals, perhaps with more than two various signals intensity or with the random order transmitted radio signal with secondary signal intensity.Importantly, radio signal is sent under different transmission intensity, and at least one radio replys in vehicle side and received by the identifying information transmitter, and is used to assess the reaction of identifying information transmitter to two emissive powers.
For example possiblely in framework of the present invention be, the incident that depends on is sent has transmitting of first signal intensity, and as the radio signal that the reaction emission of second incident is had secondary signal intensity.
If for example stop back record car door opening at vehicle motor, can respond the identifying information transmitter with first emissive porwer so, this identifying information transmitter produces the RSSI value and it is postbacked vehicle for this response each time.As long as the carrier of identifying information transmitter gets off, said RSSI value shows diminishing of the signal intensity that receives, and this is away from antenna because of the identifying information transmitter.The button of closing as if on the present for example operated door of the user who has got off so just sends the radio signal with secondary signal intensity, and said radio signal identifying information transmitter is sent answer signal again.The order of RSSI value is during getting off; And also after altered second radio signal with the emissive power that has strengthened is sent, carrying out confidence level checks; Especially check, whether the order of said RSSI value passes through corresponding to the user's who gets off change in signal strength.
If this situation is authorized the closing function of car door so.This example is explained in detail below.
Corresponding method (signal of vehicle side is delivered to the identifying information transmitter with distinct transmit power in said method) can use the different event of vehicle to trigger; For example the door sensor opposite house is opened or the request responding of locking a door, and the sensor's response of asking starting engine in addition.
Description of drawings
Next by the present invention of the explained in detail of form of implementation shown in the accompanying drawing.In the accompanying drawing:
Fig. 1 has illustrated the layout of antenna in motor vehicle and the field distribution during at distinct transmit power in schematic view;
Fig. 2 is the exemplary first method flow process that is used to open motor vehicle automobile door by the present invention;
Fig. 3 is the exemplary second method flow process that is used to open motor vehicle automobile door by the present invention;
Fig. 4 is used for the third exemplary method flow that door locks by the present invention;
Embodiment
As shown in Figure 1, non-central ground just in the zone of pilot set, for example is furnished with antenna 2 under pilot set in motor vehicle 1.Antenna 2 can be controlled so that launch the signal with different transmission power.In the example shown, can be controlled so that launch with three distinct transmit power.Broken circle 3a representes the coverage in principle by the observable signal of identifying information transmitter; This can be obtained (in fact field distribution is not circular or spherical, but this is inessential as far as this explanation) at (just in three signal intensities minimum) under first signal intensity.The field coverage of the emission that circle 3b representes to carry out with second middle signal power, Fig. 3 c then illustrate the emission of carrying out with the 3rd high transmit power.
Can know that directly bigger emissive power comprises the zone that reaches with less emissive power.But, in inquiry circulation, can know more reliable conclusion about the place of the identifying information transmitter of replying request signal through the emission of carrying out with different transmission power.For example be among the round 3c but be not in the identifying information transmitter in the round 3a, for example be considered to uncommitted to start vehicle.Be among the round 3a and then also be in the identifying information transmitter among the 3c thus; Difference according to the security configuration of vehicle; Do not regard the rear parcel shelf of the unlock that is to have the right in case of necessity as, so that the third party uses without permission when preventing for example to be parked in the traffic lights place.
When the signal intensity that transmits of also knowing antenna 2 according to improvement project identifying information transmitter of the present invention, and as information retransmission when the motor vehicle, can infer between identifying information transmitter and motor vehicle has undisturbed and unspoiled the connection.The identifying information transmitter that is for example carried by the user who uses the driver door, in the inquiry of carrying out with signal intensity 3b, feedback ratio is littler emissive power in the inquiry of next carrying out with emissive power 3c.If the order of the signal intensity of this loopback be not in the framework of credibility control in acceptable deviation with consistent by the emissive power of vehicle performance, so just refuse the use of the corresponding function of motor vehicle.On the other hand, for example when the identifying information transmitter does not provide feedback in the inquiry of carrying out with signal intensity 3a (when controlling maybe in contrast), the use of refusal engine start function with signal intensity 3c.For example can know that in this case the identifying information transmitter is in outside the vehicle, and therefore not allow engine start.
By this way, search order can have multiple combination, wherein, also can use more than three various signals intensity or also can only use two various signals intensity.Allow again in assessment especially accurately differentiation during according to the extra refinement of improvement project by identifying information transmitter signal intensity (RSSI value) passback, that receive.
For example state method now, this method belongs to by method of the present invention.
Be used for the method that controller motor-car car door opening ground uses by of the present invention shown in Fig. 2.In step 10, survey the user near door or to the manipulation of door handle.As reaction, in step 11, has the identifying information transmitter that first signal of first signal intensity should be carried to the user by acentric antenna transmission to this detection.In step 12, verify whether have the effective response of identifying information transmitter.If not this situation is interrupted said method so, and system gets into sleep pattern in step 13.If the identifying information transmitter has carried out the feedback by regulation, in step 14, have second of the signal intensity that improved so and transmit by acentric antenna transmission.Whether checking again exists the believable of identifying information transmitter to reply in step 15.If do not exist, transfer sleep pattern 13 so to.In step 16, assess the value of RSSI value that returns by the identifying information transmitter or the signal intensity that detects.Said value is receiving signal 11 or 12 and 15 transmission of replying with the identifying information transmitter in 14 o'clock respectively in this example.Checking R SSI value is controlled acentric antenna to the credibility of following transmit signal strength with this signal intensity.If the RSSI value through certificate authenticity, does not transfer sleep pattern 13 to so.If RSSI successfully passes through certificate authenticity, in step 17, open the signal of the sound of door and transmission light so.
With reference to figure 1 and Fig. 2, in step 11, carry out the emission of first signal with the signal intensity of the field distribution 3b in the corresponding diagram 1.Secondary signal intensity is the transmit signal strength 3c in the corresponding diagram 1 in step 14.
The modification of the method among Fig. 2 has been shown in Fig. 3, and wherein step 10a, 11a and 14a carry out with the same way as like corresponding steps among Fig. 2.But cancelled shown in figure 2, to the intermediate steps 12 of first first checking of replying that transmit.Or rather, whether checking exists the answer of identifying information transmitter, this answer to comprise not only to transmit to first but also to the second RSSI value that transmit in step 15a.The identifying information transmitter correspondingly only sends an only answer signal in order to save energy therewith, has transmitting of unlike signal intensity although received two.In step 16a with Fig. 2 in step 16 similarly verify, whether can get rid of that the radio distance prolongs or relay station is attacked (Relay-Station-Attacke) by the signal strength values that in the replying of identifying information transmitter, provides.If this checking is sure, the signal of in step 17a, opening the sound of door and transmission light so arrives the user.
Fig. 4 shows a kind of alternative methods and implements, wherein, in this case, the authority that locks of inquiry door.
Start at 20 o'clock in method, the door that door sensor obtains after engine stops to be opened, thus reasoning user's the possible demand of getting off.Be triggered as follows through this incident, that is, repeatedly (handled with predetermined time duration or up to the door dead lock more precisely) to keep the first identical emissive power to transmit with acentric antenna.If in 40 seconds predetermined time duration for example, the door dead lock 25 of door is not handled, in step 21, confirm overtime so and transfer sleep pattern 22 to.During the stand-by period, handled up to door control pick-up 25, to acentric antenna sent, transmitting of under the first identical signal power, sending, in the identifying information transmitter, obtain the sequence (step 23) of RSSI value.In case in step 24, confirm the manipulation of door dead lock 25, in step 26, transmit with the emissive power that has improved so, and reply with information about the signal intensity that receives by the identifying information transmitter by acentric antenna.In step 27, the confidence level of the RSSI value of check passback.The RSSI value sequence that in step 23, finishes for example possibly not be given in terminal rising of sequence and surpass the signal intensity of predetermined threshold, this be because this possibly indicate the user in motor vehicle stop and by the manipulation of third party's opposite house dead lock.In addition, the replying of identifying information transmitter that has (with the emissive power that has improved transmitting of sending) signal intensity must be believable relation with the signal intensity of emissive power first sequence and that sent.If successfully through check, door locks in step 28 so, and in step 29, transfers sleep pattern to.If RSSI checking negates, door release and in step 31, send the caution signal of optics or acoustics in 30 so.
Multiple flexible program is possible in framework of the present invention.Importantly, by in the only query script of the present invention via a plurality of various signals intensity of only antenna transmission.
