Abstract

According to the invention, when triggered, a portable encoder transmits a response signal, which contains code information that is specific to said encoder (2). The code information contained in the received response signal is compared with reference code information in a receiving unit (4), which is located in the object and is connected to an evaluation unit (9). In addition, both the distance of the encoder (2) from the receiving unit (4) and the receiving level of the response signal are measured on the object side and the position of the encoder (2) is calculated from said measurements. This permits a differentiation to be made between the exterior and interior regarding the position of the encoder (2). Access is released and authorisation is granted, only if the position of the encoder (2) is identified as permissible.

Identification system for verifying an authorization for access to an object or the use of an object, in particular of a motor vehicle

The invention relates to an identification system for verifying an authorization for access to an object or the use of an object, in particular a motor vehicle.

called radio-based identification systems, also RF-ID "Radio Frequency Identification" systems, finding, for example, as a replacement for mechanical key systems, access protection for computer or about automatic payment systems increasingly Menden use. An RF-ID system consists of an electronic identification mark (hereinafter referred to as encoder), which is also called electronic key, RF-ID tag ID transmitter or ID card, the user carries with him or is at an object to be identified angeord- net. the code transmitter is a characteristic code (code information) fitted. This code is usually on an object-side base station retrieved (hereinafter also referred to as object-side transmitting and receiving unit) from the encoder and subsequently authenticated or ve rifiziert. The code can also by other triggering mechanisms triggered by code transmitter is sent to the object.

Various radio-based transmission technologies are common or possible: LF or LF systems in the frequency range of 100-300 kHz, RF or RF systems at 433 MHz (315 MHz) or

867 MHz radio frequency and microwave systems, most of which 2.4 GHz, 5.8 GHz, 9.5 GHz or 24 GHz at the frequencies.

A distinction is made between code donors an active and a passive identification. The passive identification is characterized in that the code transmitter, can be interrogated without user from the transmitting and receiving unit constantly. the code transmitter is within a certain distance range to the transmitting and receiving unit, so the communication between the transmitting and receiving unit and a code transmitter takes place automatically or, for example triggered by manual actuation of a switching device, such as by actuating a door handle by the user. The limitation of the distance range generally results from the pathloss. Sending the Abfragesig- Nals and then triggered response signal is referred to as a question and answer dialogue.

In an active identification system, however, the communication is actively initiated by the user at the encoder. The user must in this case therefore usually operate the encoder manual for an example, and then simultaneously press the door handle to open the door. The user has to perform more manual labor. For reasons of increased comfort passive identification systems are increasingly finding application.

that can be intercepted by unauthorized persons and un- desirable for one of the transmission channel unnoticed and to an arbitrary, in principle time by an "attacker" A disadvantage of such identification systems. By a suitable means, it is an attacker therefore normally possible to gain unauthorized access to the code making and thus to overcome the actually desired protective function.

In a prior art identification system (DE 198 36 957 Cl or WO 01/89887 AI) is an attempt to increase security against unauthorized use or unauthorized access as a result of listening to the question and answer dialogue. In this case, a first interrogation signal is transmitted from the base station, the recom- fishing power on the encoder is measured. Subsequently, a second interrogation signal is emitted under changed transmission conditions, the received power is also measured in the encoder. Only when the reception powers are different, the code information contained in the response signal is evaluated.

In this identification system two question-answer dialogues must always take place at least before the access or use can be released. Even if this means the security against unauthorized use or unauthorized access is increased, the multiple dialogue at the cost of OEG liehst quick access. Because the user should not be impaired in its usual procedure by running question-answer dialogue.

On the other hand, a disadvantage of LF and RF identification systems is that an accurate determination of the location of the encoder can be carried out relatively inaccurate in relation to the object.

In a further, known identification system (DE 199 57 536 AI) is attempted to increase the security against unauthorized use or unauthorized access as a result of listening to the question and answer dialogue, by the removal of the encoder is determined to the object and only within a predetermined Distance encoder located as methods entitles the holder. However, the measurement of the distance may be erroneous, if shadowing of the transmitted signals is present, supply by the direct communication between the code transmitter and the base station or is severely hampered.

An object of the invention is to provide an identification system by the improved security against unauthorized use or unauthorized access is provided. Another object of the invention is to determine the exact position of a code generator for the object. It is also a goal, as regards the place of the encoder between a

to clearly distinguish (within the object) and an outer space (outside the object) interior. These objects are achieved by an identification system having the features of patent claim. 1

In this case, a portable code transmitter for triggering (such as after receipt of an interrogation signal or by manual actuation of a trigger switch) at least transmits a response signal. The response signal has a characteristic of the code transmitter code information by the code transmitter proving his right. In an object-side reception unit and an evaluation unit connected thereto, the code information included in the received response signal is compared with a reference code information. In addition, both the Empfangspe- gel of the response signal and the distance between the code transmitter and receiver units is measured on the object side. From this, the position of the encoder is determined for the object. If on the one hand the code information on the other hand the position of the encoder is recognized as in a predetermined area located at least substantially coincides with the reference code information and, a release signal is generated for controlling a safety assembly.

With this identification system, the position of the code generator can be determined very precisely, irrespective of whether it is within the object o- (for example, a motor vehicle) located outside of the object. Depending on different security units can then be driven (for example, the closure system or immobilizer of a motor vehicle) from the position.

Advantageous developments of the invention are given in the dependent claims.

Thus, the distance measuring device can determine the distance between code transmitter and the receiver unit via a phase measurement or transit time measurement of the signal duration of the response signal. The response signal itself is utilized here to measure the distance. There is no need for separate from the question-and-answer dialogue distance measuring device. By reflected signals (known as multipath propagation), a plurality of (in some cases also redundant) obtained distance information, which can be used for more precise position determination and also for internal-external space discrimination.

In addition to the distance measurement is determined by the Pegelmessein- direction of the receiving level or field strength of the received response signal. a distance between the code transmitter and receiver unit is thus determined by comparison with one or more predetermined reference values ​​(reference table). This can be used to verify the distance values ​​obtained in the above loading advertised distance measurement. For the measurement of field strength amplitude of current and / or voltage in the receiver can be measured. With a known amplitude and known during the transmission attenuation ratios and decay behavior of the field strength, the distance can be determined by the ratio of the transmitted amplitude / field strength / level and the received amplitude / field strength of the electromagnetic field. Again, the response signal is used for distance measurement. A separate signal is not required.

a plurality of receiving units are advantageously arranged spatially separated from one another in the object. Each receiver unit may then be connected to a common evaluation unit. If ladle gene Pegel, and the propagation time between the code transmitter and the respective receiving unit is determined for at least two receiving units of e, so the position of the encoder can be more accurately determined. Here method of triangulation can be used more accurately determine the position by the or the previous measurement can be rifiziert ve safely. The evaluation of the results can be carried out using a receiver unit and are then communicated to the evaluation unit or carried out in the central evaluation unit.

It is very advantageous in addition, to arrange one or more transmitter units in the object, which emit an interrogation signal when triggered. In particular, a simple reference, can be used for runtime measurement are obtained when the transmitting unit is connected to the evaluation. the time between the transmission of the interrogation signal and receipt of the response signal is then used as runtime. It then needs to be transmitted along any time information in the response signal.

The signals need not be transmitted at different frequencies, but can advantageously be in a single, preferably high-frequency or microwave range located carrier frequency (which is application for the respective arrival also approved by mail) are transmitted.

It is also very advantageous for several arranged distributed on the object receiving units provided. Thus, the distance between the code transmitter and receiver unit and / or the level of the response signal may be measured by each receiving unit. It can also be measured by a receiving unit of the distance and the other receiving unit of the levels.

If the evaluation unit comprises an evaluation device up, which weights the measured level and distances with weighting factors, the particular conditions at the object can be considered. For example, the level at the receiving units have a characteristic course, if the encoder from the outside space into the interior loading moved. Similarly, the distance measurements show a characteristic curve (particularly when the distance measurements are carried out successively in time). This information can be transmitted, for example in a weighted level-distance matrix, and for deciding whether the code transmitter is located in the vehicle or not, be used. Thus, the distance and level information can be weighted differently, and this depends on the location of the respective receiving device to determine the position of the encoder exactly. The measured values ​​are entered into a weighted-level distance matrix, appropriate mathematical methods for further processing of the measured values ​​can advertising applied to the to obtain the exact position of the encoder.

If the object is requested in the present or would like to use a driver, a vehicle is, the security unit is a closed system or an immobilizer. With the aid of the position determination can be accurately determined whether the position of the encoder outside or inside the motor vehicle. Depending on different security units can be addressed and thus different functions are triggered when it detects authorization of the co degebers. Thus, even the interior light could for example at even far away encoder together with the unlocking of the doors are turned on (or the horn are actuated briefly) so that the motor vehicle in a parking lot or at night can be found better. If the code transmitter, however, detected in the motor vehicle, so even user-specific settings can be made (such as seat or mirror position) in addition to releasing the immobilizer.

With the exact position can be also reliably distinguish whether the code transmitter inside the vehicle or outside is. Depending on the access (locking or unlocking of the locking system) and another time using (releasing the immobilizer) in adults known per authorization can then again be released. The identification system is not limited to the use in a motor vehicle. It can also be used with other objects, such as personal computers, mobile phones, smart cards or other in which an authorization for access control or user is queried and the code transmitter in the vicinity of the object to be in order to qualify permitted devices.

An embodiment of the invention is turned on in the following hand of the schematic drawing illustrated in more detail. Show it:

1 shows a block diagram of an identification system according to the invention and Figure 2 an identification system according to Figure 1 arranged in a motor vehicle.

In the following, an identification system for verifying an authorization for access to an object or the use of an object using the example of a motor vehicle is explained as an object. The identification system can of course be used with other objects where access is allowed only after proof of authorization as initially blocked, for example, a computer, a phone, an ATM, a building, garages or other areas.

The identification system to a two-way dialogue here (also referred to as a question-and-answer dialogue) between a base station 1 (Figure 1) with a transmitting and receiving unit and a mobile, portable by a user code Switch 2 for proof of authorization for access perform or use.

The object-side transmitting and receiving unit comprises at least one transmitter 3 and at least one receiver 4, which in each case with transmitting and / or receiving antennas 5 are connected, can be sent via the signals and received. The antennas 5 are at exposed points in the motor vehicle (see FIG. 2), so that signals can be sent into the interior of the motor vehicle and in the vicinity of the motor vehicle with sufficient field strength and signals therefrom can be sufficiently well received.

In the motor vehicle safety units which are not illustrated (such as door locks o- for access to the motor vehicle of an ignition / steering lock 6 for an immobilizer) arranged for the use of the motor vehicle, the only proof of authorization with the aid of a coded release signal to a comparable or unlocked state can be controlled. In addition to the credential to the code transmitter 2 must (or a closely predetermined position range) in the vicinity of the motor vehicle or within the motor vehicle is actually in a certain predetermined position, so that the appropriate actions / functions can be triggered.

For accurate position determination both a distance measuring device 7 as well as a level measuring device 8 is required according to the invention, which are each connected to an evaluation unit. 9 To check the correct code information, a demodulator 10 is required, which extracts the code information to the response signal and supplies it to the evaluation unit. 9 The evaluation unit 9 compares the code information with a stored in a reference memory 11 reference code information. In at least largely match the permission is at least detected. If then the position of the code transmitter 2 - if appropriate, depending on the operating state of the object based on the level and the distance measurement - as in an approved position is detected, appropriate functions or actions can be triggered on the property.

Each object associated with the code transmitter 2 in turn comprises a transmitter 12 and a receiver. 13 The code transmitter 2 can receive signals (interrogation signals) and signals (response signals) with the aid of an encoder 14 encodes send via the transmitter 12th Typically, it is used to emit a coded response signal with the code information to the access authorization or the use of the object is rejected demand.

In the present identification system an authorization is only detected when the one hand, the base station 1, the correct coded response signal and demodulating therefrom te receives code information and on the other hand located the position of the encoder 2 as in a specific position in the vicinity of the motor vehicle or within the motor vehicle is recognized.

For triggering the response signal, a switch in the range of an access door, for example, (in Figure 2, this is the driver's door) can be manually operated. When the user brings his hand, for example in the vicinity of the door handle or these touches / is operated, an interrogation signal is triggered by the vehicle side transmitter 3 and transmitted.

Further, the interrogation signal may also be triggered by automatically detecting the position of the encoder 2 in a certain distance from the vehicle. If the encoder 2 receives the interrogation signal, it in turn emits a response signal, which is received by the vehicle-side receiver. 4 Since in the embodiment of the code transmitter 2 only a response signal when it has previously received an interrogation signal, it can also be referred to as a transponder.

Now the distance from the encoder 2 and the object on the one hand averages ER- (for example the measurement of the signal propagation time of the response signal or the running time of the signals between the transmission of the interrogation signal and receiving the response signal). This can be done or a phase measurement by means of time measurement (with the aid of timers in both the object and the encoder 2 as appropriate). In the solution Zeitmes- the signal propagation time is measured directly or indirectly and determined with a known signal propagation rate of the distance. In the phase measurement, the change in phase is measured relative to the transmitted phase. The phase change is a measure of the distance traveled with a known speed of propagation of the signal.

It is advantageous if the transmission time or the phase of the interrogation signal in the determination of the distance is considered as a reference (dashed connection between the blocks "Sender" and "distance" in Figure 1).

Measuring the transit time of a signal or a path that travels a signal is, the skilled worker examples play, also of radar principles (FM-CW radar) is known. In more detailed explanation is omitted here.

On the other hand, the level / amplitude / field strength of the received signal is determined. If it is known, with which level the response signal is sent so can be calculated using the known transmission loss and the transmission media how far the code transmitter is removed. 2 For measuring the level, a current or voltage measurement of the received signal can be made. In addition, certain level-space pattern as a result of "movement" of the encoder 2, the user carries with him, are observed, which can be used for a verification of the measured distances.

If the encoder 2 with its own power supply (battery) is supplied with power, and the operating time can be taken into account in the level measurement, since the battery voltage with time becomes smaller, and thus the emitted level is more and more reduced with time. Then, in the evaluation unit 9 the measured level should be provided with a time correction factor that accounts for the level reduction with time. In the level measurement of the absolute level can be used as a benchmark. Likewise, it is possible to perform a relative level measurement in which the measured level is correlated with egg nem previously measured levels, and only the difference is further used as the measurement variable. In the relative level measurement, the level of signals can be measured, which are received through different antennas. 5 These measured levels can be related to each other (ie, difference). Thus, the

Levels of signals to be measured, the so-called ßenraumantennen of Au (arranged externally on the motor vehicle) are received and these are correlated with levels of received signals (disposed within the motor vehicle) via so-called indoor antennas. From the difference of the two levels, the distance can be determined or the position of the encoder 2 between exterior and interior are distinguished.

The position of the encoder 2 can be determined more accurately when more than one distributed respectively receive the response signal in or arranged on the object receiver. 4 Then can be spatially determined using geometric means (e.g. triangulation) and the level measurement of the position.

It is in any case advantageous to arrange several receiver 4 at the object. Thus, also a movement of the encoder 2 could be detected, or the side from which the code transmitter 2 the object is approximated. appropriate actions are triggered - depending on the position can then - in cases of justified code information. the boot lid unlocked first and optionally open - For example - when approaching the trunk 15th After a period of door locks can then be released one or more.
