In order to the use of the suitable safety and self-propelled vehicle of guaranteeing self-propelled vehicle at any time, formulate the standard that recognized in insurance, this system of entering must meet.Especially known so-called Thatcham standard here.Described standard also confirms how far specific electromagnetic antenna field can extend at most at vehicle outward.
In vehicle, the use of multiple antenna brings the maintenance cost that improve, the cost that improve and fault liability.
By a kind of known method of EP 2070780, the only antenna with different emissive powers of the method manipulation.This antenna arrangement in the side direction of central longitudinal axis, and depends on and will use which car door and manipulate with different emissive powers.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of method, to be the failure-free control of access entitlements or rights of using, uses less antenna in vehicle.
According to the present invention, this technical matters is solved by a kind of method with following steps, namely, control setup by vehicle side manipulates the antenna in described self-propelled vehicle, to send the identifying information transmitter of the first radio signal to movement with the first emissive power, in described vehicle non-centrally, namely relative symmetrical plane is longitudinally arranged in driver side with passing to described antenna; Described first radio signal is received in the identifying information transmitter of movement; Manipulate the same antenna in described self-propelled vehicle, to send the identifying information transmitter of the second radio signal to described movement with altered second emissive power; In the identifying information transmitter of described movement, receive described second radio signal, wherein said identifying information transmitter knows the signal strength of the signal received, and converts it into signal strength values respectively; The device that at least one radio replys vehicle side is sent by described identifying information transmitter, wherein, described radio response packet containing about known by described identifying information transmitter, for the information of the signal strength values of at least two radio signals sent; At least one radio response of the identifying information transmitter of described movement is received in vehicle side; Assess the described radio response of described identifying information transmitter to know described rights of using; Depend on this assessment to open or forbid described requested function.
According to the present invention, provide a kind of for checking the method for the rights of using of the requested function to self-propelled vehicle.
Once record the request of function, then by least one antenna in the control setup manipulation self-propelled vehicle of vehicle side, to send the first radio signal under the first emissive power.Antenna sends radio signal in the space limited by emissive power, and this space extends at the peripheral location of antenna.Active distance depends on the ambient environment of power, antenna performance and antenna at this.But the power needed not only can have been known by analogue computing but also rule of thumb for special vehicle.
First radio signal is received by the identifying information transmitter of movement, as long as this identifying information transmitter is in the active distance scope of the antenna in the first emissive power.In form of implementation of the present invention, identifying information transmitter Received signal strength and with the first radio response transponder motor-car.Before the response of signal, can carry out with the content verification of the message of this Signal coding, and checking can be depended on to send answer.The radio response of identifying information transmitter is received in vehicle side.Antenna is in a motor vehicle manipulated for sending the identifying information transmitter of the second radio signal to movement with altered second emissive power, this identifying information transmitter receives again, if desired analyze and reply described signal.The radio response of identifying information transmitter is analyzed to know rights of using in vehicle side, and depends on assessment or analyze open or forbid or not open requested function.
According to the present invention, by identifying information transmitter know received signal signal strength, change into signal strength values and this signal strength values be delivered to the control setup of vehicle side as the value after coding in radio is replied.
Knowing of the intensity transmitted is substantially known in the radio communication.Such as received signal strength index (RSSI) is in the radio communication for the yardstick of received field intensity.In this value, determine a value without unit between 0 to 250, this value provides received signal strength.This RSSI value is delivered to the device of vehicle side by identifying information transmitter.Because in vehicle side, the signal strength of launching is known, and because the change of the signal strength when the radio signal in succession sent, and because the arrival of the notice of identifying information transmitter (which kind of intensity receive described signal with), so detailed assessment is possible.In Credence test, especially can improve the safety of system, attack or the prolongation of radio distance because so-called repeater station can be got rid of.
Present invention utilizes in inquiry circulation and there is the communication of different field intensity and the feedback to the emissive porwer received in identifying information transmitter.
By under the different emissive power of the antenna in vehicle side to the repeatedly inquiry of identifying information transmitter, can make up many following shortcomings, described shortcoming exists concerning the system only in other cases with an antenna compared with having the system of multiple antenna.Relative to mentioned prior art, present invention utilizes in query script with the manipulation that different emissive powers is carried out antenna.Namely assess the feedback to repeatedly wake-up call of identifying information transmitter, described wake-up call can send when change in signal strength.
The response of identifying information transmitter does not need directly to carry out upon receipt of the signals according to the present invention.Or rather, also multiple response can be transmitted in response packet.In the latter case, the device of vehicle side before the secondary signal with altered emissive power is stopped, wait for one predetermined time section.
According to an example maneuvering engine start button.First under the first transmitted power, use the transmitting of wake-up signal, the transmitting of this wake-up signal can by identifying information transmitter with the record of the first signal strength.Under the second emissive power such as expanded, identifying information transmitter can receive and record corresponding higher emissive power, and this can not be this situation when radio distance extends.Postback, be taken into account about the information of the emissive power received by identifying information transmitter, so that it is more reliable to make to enter control.Especially check, whether the transmission signal contact returned by identifying information transmitter is credible to predetermined transmission signal.The present invention advantageously utilizes again the transmission of multiple signal strength in proof procedure.
In the general design plan of described method, identifying information transmitter can with the multiple vehicle side of only radio response response recorded transmit, such as, after two that obtain vehicle transmit.In described radio response, the information of the signal strength of the signal received about two can be comprised.In an only message of identifying information transmitter, jointly carry out transmission advantageous particularly, be sent out this is because reply needs due to less radio, the energy of reserve of identifying information sender side is protected.
In a kind of form of implementation of the present invention, for transmitting of identifying information transmitter record, know emissive power immediately and pass back to vehicle.Namely in the response of each radio signal, answer is delivered to vehicle.Then individually receive response in vehicle side, and jointly consider to assess.When the other transmission with the signal of altered intensity depends on the reception of response, this mode is favourable.
According to a kind of form of implementation of the present invention, antenna arrangement is acentric position in a motor vehicle, and wherein, non-centrally to mean in this linguistic context, antenna, relative to the symmetrical plane of vehicle, is especially arranged relative to vertical symmetrical plane longitudinally with staggering.
Because the identifying information transmitter with multiple different field intensity is verified, so can infer the position of identifying information transmitter relative to vehicle in checking flow process.Such as possible as follows, that is, by means of acentric position with the first emissive power and with the scope of field strength distribution cover in vehicle with car door before region, but do not cover away from side on car door before region.At this, field strength distribution scope does not obviously refer to physically possible or unlimited field strength distribution, but considers field intensity that be technically correlated with, that namely can be able to measure in the triggering limit of identifying information transmitter.
In second emission process, use second, larger or less emissive power defines the location of identifying information transmitter further.
Importantly, multiple radio signal is sent to identifying information transmitter by method of the present invention by vehicle side.At least two in described radio signal send with different signal strengties.But be also possible as follows according to the present invention, namely, send multiple radio signal with the first signal strength, and send one or more secondary signal with secondary signal intensity, or with more than two different signal strengties or with random order transmitted radio signal.Importantly, radio signal sends under different transmission intensity, and the response of at least one radio is received by identifying information transmitter in vehicle side, and for assessment of the reaction of identifying information transmitter to two emissive powers.
Such as in framework of the present invention it is possible that the event that depends on sends have transmitting of the first signal strength, and as the reaction of second event transmitting being had to the radio signal of secondary signal intensity.
If such as record car door opening after vehicle motor stops, so can responding identifying information transmitter with the first emissive porwer, this identifying information transmitter is that this response produces RSSI value and postbacked vehicle each time.As long as the carrier of identifying information transmitter gets off, described RSSI value shows diminishing of the signal strength received, this is because identifying information transmitter is away from antenna.If the closedown button in the present such as operated door of the user got off, so just sends the radio signal with secondary signal intensity, sends acknowledge signal again to described radio signal identifying information transmitter.The order of RSSI value is being got off period, and also after the second radio signal that is altered and emissive power that is that enhance sends, carry out Credence test, especially check, whether the order of described RSSI value passes through corresponding to the change in signal strength of the user got off.
If this situation, so authorize the closing function of car door.This example is explained below in detail.
Corresponding method (signal of vehicle side is delivered to identifying information transmitter with different emissive powers in the process) can trigger by the different event of vehicle, the such as response of the unlatching of door sensor opposite house or the request of locking a door, and also have the response of the sensor of asking start the engine.

Detailed description of the invention
, namely in the region of driver's seat, such as, driver's seat under be furnished with antenna 2 as shown in Figure 1, in self-propelled vehicle 1 non-centrally.Antenna 2 can be manipulated to launch the signal with different transmission power.In the example shown, can be manipulated to launch with three different emissive powers.Broken circle 3a represents the active distance in principle by the observable signal of identifying information transmitter, this under the first signal strength (namely minimum in three signal strengties) can be acquired (in fact field distribution is not circular or spherical, but this is inessential for this explanation).Circle 3b represents the field active distance of the transmitting carried out with the signal power of second centre, and Fig. 3 c then illustrates the transmitting carried out with the 3rd most high transmit power.
Directly known, larger emissive power comprises the region reached with less emissive power.But by the transmitting carried out with different transmission power, the more failure-free conclusion in the place of the identifying information transmitter about response request signal can be known in inquiry circulation.Such as to be in round 3c but the identifying information transmitter be not in round 3a, such as, to be considered to uncommitted to start vehicle.Be in round 3a and then the identifying information transmitter be also in thus in 3c, according to the difference of the security configuration of vehicle, not regarding as if desired is the rear parcel shelf of unlock vehicle of having the right, so that the third party uses without permission when preventing from being such as parked in traffic signal lamp place.
When also knowing the signal strength transmitted of antenna 2 according to improvement project identifying information transmitter of the present invention, and as information back to self-propelled vehicle time, can infer identifying information transmitter with have undisturbed and unspoiled connection between self-propelled vehicle.Such as by the identifying information transmitter using the user of driver door to carry, in the inquiry carried out with signal strength 3b, the emissive power that feedback ratio is less in the following inquiry carried out with emissive power 3c.If the order of the signal strength of this loopback is not consistent with by the emissive power of vehicle performance in acceptable deviation in the framework of credibility control, the so just use of the corresponding function of refusal self-propelled vehicle.On the other hand, such as when identifying information transmitter does not provide feedback in the inquiry carried out with signal strength 3a (when manipulating with signal strength 3c may in contrast), the use of refusal engine starting function.Such as known in this case, identifying information transmitter is in outside vehicle, and does not therefore allow engine starting.
By this way, search order can have multiple combination, wherein, also can use more than three different signal strengties or also only can use two different signal strengties.Allow again especially accurately to distinguish when assessing that returned by identifying information transmitter, that receive signal strength (RSSI value) according to the extra refinement of improvement project.
Such as state method now, the method belongs to by method of the present invention.
Shown in Figure 2 by of the present invention for the method that uses of controlling machine motor-car car door opening ground.In step 10 detect user close to door or the manipulation to Door Handle.As the reaction to this detection, send by acentric antenna the identifying information transmitter that first signal with the first signal strength should carry with to user in a step 11.Verify whether there is the effective response of identifying information transmitter in step 12.If not this situation, so interrupt described method, and system enters sleep pattern in step 13.If identifying information transmitter has carried out the feedback of as prescribed, by acentric antenna transmission, there is second of the signal strength that improve so at step 14 and transmitted.Again verify whether there is the believable response of identifying information transmitter in step 15.If do not exist, so transfer sleep pattern 13 to.In step 16, the value of the RSSI value returned by identifying information transmitter or the signal strength detected is assessed.Described value is transmitted with the response 12 and 15 of identifying information transmitter in this example respectively Received signal strength 11 or 14 time.Checking R SSI value, to the credibility of following transmit signal strength, manipulates acentric antenna with this signal strength.If RSSI value by certificate authenticity, does not so transfer sleep pattern 13 to.If RSSI successfully passes through certificate authenticity, door capable of being opened and send the signal of the sound of light so in step 17.
With reference to figure 1 and Fig. 2, carry out the transmitting of the first signal in a step 11 with the signal strength of the field distribution 3b in corresponding diagram 1.The transmit signal strength 3c of secondary signal intensity at step 14 in corresponding diagram 1.
Figure 3 illustrates the modification of the method in Fig. 2, wherein step 10a, 11a and 14a perform with the same way of corresponding steps in such as Fig. 2.But the intermediate steps 12 eliminated shown in figure 2, to the checking of the first the first response transmitted.Or rather, verify the answer that whether there is identifying information transmitter in step 15a, this answer comprises the RSSI value not only transmitting for first but also transmit for second.Identifying information transmitter correspondingly only sends an only acknowledge signal, although have received two to have transmitting of unlike signal intensity to save energy.Similarly verify with the step 16 in Fig. 2 in step 16a whether can get rid of radio distance by the signal strength values provided in the response of identifying information transmitter and extend or repeater station attack (Relay-Station-Attacke).If this checking is affirmative, so in step 17a door capable of being opened and the signal sending the sound of light to user.
Fig. 4 shows a kind of alternative method and implements, wherein, in this case, and the authority locked of inquiry door.
When method starts 20, the door that door sensor obtains after the engine is stopped is opened, the possible demand of getting off of reasoning user thus.Be triggered as follows by this event, that is, with acentric antenna repeatedly (more precisely with predetermined time length or until door git is handled) to keep the first identical emissive power to transmit.If in the predetermined time length of such as 40 seconds, the door git 25 of door is not handled, and so in step 21, confirms time-out and transfers sleep pattern 22 to.Until door control pick-up 25 is handled during wait time, for acentric antenna sent, transmitting of sending under the first identical signal power, in identifying information transmitter, obtain the sequence (step 23) of RSSI value.Once confirm the manipulation of door git 25 in step 24, transmitted with the emissive power that improve by acentric antenna so in step 26, and by identifying information transmitter to reply about the information of the signal strength received.In step 27, the confidence level of the RSSI value of inspection passback.The RSSI value sequence of having carried out in step 23 such as may not be given in the signal strength that sequence end is increased beyond predetermined threshold, this is because this may indicate user's stop in a motor vehicle and the manipulation by third party's opposite house git.In addition, have the identifying information transmitter of (what send with the emissive power that improve transmits) signal strength response must with First ray and the signal strength of emissive power that sent be believable relation.If successfully through inspection, so door locks in a step 28, and transfers sleep pattern in step 29.If RSSI checking is negative, so door unlocks and in step 31, sends the warning signal of optics or acoustics in 30.
In framework of the present invention, multiple flexible program is possible.Importantly, multiple different signal strength is being sent by only query script of the present invention via only antenna.
