Abstract

Key lock has lock (3) and control equipment (4) with receipt mechanism (6) for receiving of opening codes (B) which are send from mobile stations (2) and reference coding memory (9) for storing reference coding (R). Comparing unit (8) compares received opening coding from reference coding stored in reference coding memory. Comparing unit is arranged in such a way that the lock unlocks if received opening coding matches with reference coding within a time span, after which received coding will have to be inserted again. Lock is locked if opening coding matches with reference coding stored in reference coding memory within a time span, after which opening coding will have to be inserted again.

Description

The The present invention relates to a locking device with a lock and a control device for locking and unlocking the lock, wherein the control means comprises receiving means for receiving at least one opening code and comparing means for comparing the received aperture coding with at least one reference coding stored in a reference memory having.

such closing devices are generally known especially in motor vehicles. In the Rule is in the key a transmitter or a transponder is arranged which transmits the aperture coding. Two approaches are known in the art.

To the One is known to be the key, though he an opening coding sends out, always the same opening coding sending out. In this case, the key sends the opening code, for example only if a button located in the handle of the key from a user pressed becomes. The control device checks whether they have the opening code receives. If you have the opening coding receives, changes it each the closed state of the lock from "locked" to "unlocked" or vice versa from "unlocked" to "locked".

To the Others know that there are several buttons in the handle of the key are, so the key several opening codes can send out, and the control device every time they open a coding receives one by the received opening coding performs certain action, For example, the lock locked or unlocked.

Independently of, which of the two above-mentioned approaches is taken, A control of the castle but only if the control device the opening code receives. In the prior art, it can therefore happen in particular that the lock remains unlocked when the user forgets the locking of the castle. The locking system The prior art is also relatively expensive, since own keys are needed in which a corresponding transponder or another transmitter must be arranged.

The The object of the present invention is a locking device the aforementioned To develop such a way that in a simple way an automated Unlocking and locking the lock is feasible.

The Task is performed by a locking device solved with the features of claim 1.

• – das Schloss entriegelt, wenn eine der empfangenen Öffnungscodierungen mit einer der im Referenzcodierungsspeicher gespeicherten Referenzcodierungen übereinstimmt und diese Öffnungscodierung nach einer Zeitspanne, in der sie nicht empfangen wurde, erstmals wieder empfangen wird, und
• – das Schloss verriegelt, wenn nach einer Zeitspanne, in der mindestens eine Öffnungscodierung empfangen wurde, die mit einer der im Referenzcodierungsspeicher gespeicherten Referenzcodierungen übereinstimmt, erstmals keine einzige Öffnungscodierung mehr empfangen wird, die mit einer der im Referenzcodierungsspeicher gespeicherten Referenzcodierungen übereinstimmt.

According to the invention, the comparison device is thus designed such that, as far as the received opening codes are concerned,

• The lock is unlocked when one of the received opening codes coincides with one of the reference codes stored in the reference coding memory and this opening code is first received again after a period of time when it was not received, and
• The lock is latched when, after a period of time in which at least one opening coding has been received, coinciding with one of the reference codes stored in the reference coding memory, for the first time, no more opening coding is received which matches one of the reference codes stored in the reference coding memory.

So far there are other circumstances concerning the action of the comparator can, can be provided that the comparison device unlocking of the castle in addition to the above conditions only triggers when the lock is still locked. Likewise, the comparison device locking the lock additionally to trigger the above conditions only if the lock is still unlocked. This consideration leads to a for the User more comfortable operation of the locking device. Also, that can Coding-controlled locking and unlocking of the lock can be switched off be.

If the control means an interface to an input device by means of which the reference codes in the reference coding memory storable and stored in the reference coding memory reference codes the reference coding memory erasable are, the control device is parameterizable. The input device may alternatively be an integral part of the control device or be solvable by it. Also, it may be part of another device, such as a car radio or an on-board computer of a motor vehicle.

The control device can be designed such that it only permits the storage of reference codes in the reference code memory and / or the deletion of reference codes stored in the reference code memory if no reference code is stored in the reference code memory or if the receiver receives at least one opening code which corresponds to one of the reference coding stored in the reference coding memory matches. Because of this, the safety of the locking device can be significantly increased.

alternative or additionally to the last mentioned Design, the control device also designed be that they are storing reference codes into the reference encoding memory and / or deleting of reference codes stored in the reference coding memory only then allows when the controller over the input device is given an activation code.

Preferably the controller has a deactivation memory for storing deactivation information for each one of the reference encoding memories stored reference codes. In this case, the controller is designed so that the deactivation information of her in Deactivation memory separately for any reference coding stored in the reference encoding memory storable and erasable. The comparison device is designed in this case, that they disabled reference codes when compared with the received opening codes not considered. Because then is in a simple way a temporary deactivation of individual Reference codes possible. This can be useful, for example, if the corresponding Mobile station is nearby the receiving device is located, but unlocking the lock is undesirable. Similar to the backup systems when entering and deleting Reference encodings may also include entering and clearing deactivation information be assured. But this is not mandatory.

Preferably the control device is designed such that at least then, when unlocking the lock, a control information to a other device than the lock can be issued. Because then it is an even more comfortable operation possible. For example, in particular, when the locking device is arranged in a motor vehicle - a car radio turned on be turned on, the interior lighting of the motor vehicle and an alarm system will be turned off. When the locking device in a building is arranged, for example, an alarm system can also be turned off and - if appropriate dependent on from external light conditions or the day and season - the Light are switched on.

The Outputting the control information or the output control information can depends on, if only a single received opening coding matches one of the reference codes stored in the reference encoding memory or if several received opening codes each one of which is stored in the reference encoding memory Reference codes match.

For example can, if the receiving device at the time of unlocking of the lock only a single opening coding receives with one of the. matches reference codes stored in the reference coding memory, the output control information depends on the reference coding which matches the received aperture coding. This is when the locking device is arranged in a motor vehicle, for example, driver-individual Settings of the driver's seat, the vehicle mirror, the car radio etc. possible.

Become however, several opening codes received, each with one of the reference encoding memory stored reference codes must be in the Usually the driver-individual attitude is omitted. In this case can only driver independent Settings are made. Additionally, if necessary an output device are controlled, which receives the received opening codes or hereby lists corresponding information, so that a selection and selection of driver-individual settings simplified becomes.

If the reference codes stored in the reference coding memory Prioritization are assigned, the output control information also be determined by prioritization.

In analogous way to output additional control information when unlocking the lock, the control device can also be designed in this way that at least when she locks the lock, a control information to a device other than the lock is dispensable. For example, the car radio can be switched off automatically If the lights are switched off, an alarm is activated be or - at Arrangement in a building - the shutdown of a stove or of the light.

Preferably is the receiving device according to the bluetooth standard educated. Correspondingly, the opening codes and the Reference encodings are Bluetooth addresses.

Due to the fact that the receiving device is designed to receive Bluetooth addresses, a very cost-effective locking system results. Because on the one hand Bluetooth receiver devices are now very kostengüns due to their widespread use tig. On the other hand, for example, the Bluetooth addresses of mobile phones of the persons who are allowed to operate the lock can be used as reference addresses. Since many people nowadays own Bluetooth mobile phones, there is no additional effort on the part of the broadcasters because they are otherwise available anyway.

The Bluetooth addresses themselves are in turn the mobile stations factory imprinted. They can not be changed by the user and are awarded only once worldwide. They therefore identify the mobile station and thus indirectly the owner of the mobile station clearly.

As already mentioned, is the closing device according to the invention preferably arranged in a motor vehicle or in a building.

Further Advantages and details will become apparent from the following description an embodiment. This show in a schematic representation

1 a locking system with a locking device and two mobile stations and

2 a memory structure.

According to 1 a locking system has a locking device 1 and several mobile stations 2 on. The locking device 1 in turn has a castle 3 and a controller 4 on. The castle 3 is by means of a key 5 Lockable and unlockable. In the unlocked state is the lock 3 - For example, by means of a handle - openable. In the locked state, this is not possible. If the lock 3 When locking should already be open, is a closing of the lock 3 still possible.

Locking and unlocking the lock 3 by means of the key 5 is purely mechanical, that is independent of the control device 4 , This is particularly important for cases in which -. B. because of lack of power to the controller 4 - a driving the lock 3 by the control device 4 is not possible (emergency operation) and the control device 4 manually override (override).

As a rule, the lock should 3 via (at least) one of the mobile stations 2 and the controller 4 be remotely lockable and unlockable wirelessly. For this purpose, the control device 4 a receiving device 6 for receiving a corresponding coding. Accordingly, the mobile stations 2 transmitting devices 7 to send out the coding. By way of example, the receiving device 6 formed according to the Bluetooth standard. The same applies to the transmitting devices 7 the mobile stations 2 , The mobile stations 2 Therefore, Bluetooth addresses B are sent out by the receiving device 6 can be received. In principle, however, a different type of communication would also be possible.

If the receiving device 6 - According to embodiment - receives a Bluetooth address B, it performs the received Bluetooth address B of a comparator 8th to. The comparison device 8th can access a reference address store 9 access. The reference address memory 9 is also part of the controller 4 ,

In the reference address memory 9 is according to 2 a number of reference addresses R storable. Further, in the reference address memory 9 for each stored reference address R additional information can be stored.

• – Drei Flags D, L, N. Im Flag D (für „deaktiviert") ist eine Deaktivierungsinformation für die korrespondierende Referenzadresse R gespeichert. Das Flag L (für „letzt") weist den Wert Eins auf, wenn bei der letzten Überprüfung der empfangenen Bluetooth-Adressen B eine der empfangenen Bluetooth-Adressen B mit der Referenzadresse R des jeweiligen Blocks 10 übereinstimmte. Anderenfalls weist es den Wert Null auf. In analoger Weise nimmt das Flag N (für „neu") den Wert Eins an, wenn bei der jetzigen Überprüfung eine empfangene Bluetooth-Adresse B mit der Referenzadresse R des jeweiligen Blocks 10 übereinstimmt. Anderenfalls weist es den Wert Null auf.
• – Die Referenzadresse R. Hier handelt es sich bei dem gegebenen Ausführungsbeispiel (vom Format her gesehen) um eine Bluetooth-Adresse.
• – Der jeweiligen Referenzadresse R zugeordnete Informationsblöcke RI. Die Informationsblöcke RI enthalten Steuerinformationen für andere Einrichtungen als das Schloss 3. Die Informationen RI werden ausgegeben, wenn das Schloss 3 auf Grund einer Übereinstimmung mit der Referenzadresse R des betreffenden Blocks 10 entriegelt wird.

According to 2 is the reference address memory 9 into several blocks 10 divided. Per block 10 There are storage elements in which the following information is stored:

• - Three flags D, L, N. The flag D (for "disabled") stores deactivation information for the corresponding reference address R. The flag L (for "last") has the value one when the received one at the last check Bluetooth addresses B one of the received Bluetooth addresses B with the reference address R of the respective block 10 agreed. Otherwise it will be null. Analogously, the flag N (for "new") assumes the value one if, in the present check, a received Bluetooth address B matches the reference address R of the respective block 10 matches. Otherwise it will be null.
• - The reference address R. Here, in the given embodiment (in terms of format) is a Bluetooth address.
• - Information blocks RI assigned to the respective reference address R. The information blocks RI contain control information for facilities other than the lock 3 , The information RI is issued when the lock 3 due to a match with the reference address R of the block concerned 10 is unlocked.

Furthermore, in the reference address memory 9 in blocks 10 ' and 10 '' still information blocks I1 and I2 stored. They too are tax information sent to a facility other than the castle 3 be issued.

If the flag D is set, the corresponding reference address R is from the comparing means 8th is treated as if the relevant reference address R is not in the reference address memory 9 deposited. The comparison device 8th is thus designed such that it simply does not take into account deactivated reference addresses R. The flags D are from the controller 4 individually storable (= settable) and erasable.

The comparison device 8th compares each received Bluetooth address B with each active one in the reference address memory 9 stored reference address R. If the comparator 8th determines a match, it sets the flag N in the block 10 in which the matching reference address R is stored. Otherwise it leaves the flag N in the non-set state. This is done by the comparator 8th with each received Bluetooth address B.

In conjunction with the setting of the flag N, the comparator checks 8th at the same time also the flag L. If this flag L is not set, this corresponds to the fact that the relevant, with the respective reference address R matching Bluetooth address B after a period in which it was not received, is first received again. The comparison device 8th therefore controls the lock in this case 3 so on, that the castle 3 is unlocked. Optionally, the comparison device 8th Before doing so, determine if the lock 3 already unlocked. If this is the case, of course, the lock must 3 not be unlocked again.

After checking all received Bluetooth addresses B with the active reference addresses R, the comparator checks 8th - For example, by means of a logical or link - whether at least one of the active reference addresses R associated flags N is set. If this is not the case, ie if not one of the respective flags N is set, the comparator checks 8th (again, for example, by means of a corresponding logical OR link), if one of the corresponding flags L is set. If this is also the case, that is, if at least one of the corresponding flags L is set, this corresponds to the fact that after a period in which at least one Bluetooth address B has been received, that with one of the reference address memory 9 stored (active) reference addresses R, for the first time no single Bluetooth address B is received, which coincides with such a reference address R. In this case, the comparator controls 8th the castle 3 such that it is locked. Optionally, the comparison device 3 Before doing so, check if the lock 3 already locked. If the lock 3 is already locked, a re-locking course can be omitted.

After checking if the lock 3 must be latched, there is a restoring the flags N in the flags L. Then, the flags N are reset. The restoring of the flags N and the resetting of the flags N may be performed by the comparator 8th or another, for example, the reference address memory 9 directly assigned device.

The mobile stations 2 may, as far as the present invention is concerned, any Bluetooth devices. Preferably, however, they are as mobile phones 2 educated. Because Bluetooth-enabled mobile phones are widely used. It is therefore not necessary to use mobile stations 2 to provide, specially and exclusively only for communication with the locking device 1 are provided. Rather, as a mobile station 2 a mobile phone that a normal user already owns.

Thus, the locking device according to the invention 1 properly perform their task, it is necessary, the "authorized" mobile stations 2 unlock. For this reason, the control device 4 an interface 11 to an input device 12 on. By means of the input device 12 are the reference addresses R in the reference address memory 9 storable. Likewise, by means of the input device 12 also reference addresses R from the reference address memory 9 erasable, as far as they are already stored there.

The input device 12 may be part of the control device 4 be. It can from the other components of the control device 4 be solvable or inextricably linked to these. It can also be an input device 12 that is part of another device. For example, as an input device 12 the keyboard / display unit of an on-board computer of a motor vehicle or the corresponding device of a car radio can be used. You may also have a mobile station 2 be used as an input device, if this has previously "identified" on their Bluetooth address B or otherwise the activation was made.

To ensure the reliability of the locking device 1 In particular, the storage of reference addresses R in the reference address memory may be ensured 9 not always possible. Rather, this release conditions must be met. For example, it is possible to store reference addresses R in the reference address memory 9 only if allowed in the reference address memory 9 no single reference address R is stored or indeed in the reference address memory 9 already at least one reference address R is stored, but at the same time from the receiving device 6 at least one Bluetooth address B is received, which is one of the in the reference address memory 9 stored reference addresses R matches. Alternatively or additionally, it is also possible to store reference addresses R in the reference address memory 9 only if the control device 4 via the input device 12 (For example, manually) a corresponding activation code is specified. Deleting in the reference address store 9 stored reference addresses R can be saved in the same way as the storage of reference addresses R.

In order to prevent unauthorized reading out of the reference address memory 9 stored reference addresses R by means of technical means are the reference address memory 9 and the comparator 8th preferably provided with appropriate security elements that make reading this data in plain text impossible.

The closing device described so far 1 represents a minimal configuration in which only the closing function of the lock 3 is controlled. The locking device 1 but can be extended.

For example, it is possible for the control device 4 when they unlock the lock 3 triggers, at least outputs the information block I1 to another device.

The information block I1 can trigger, for example, the deactivation of an alarm system or the switching on of the interior lighting of a motor vehicle. The information block I1 is output in this case, regardless of whether only a single received Bluetooth address B with one of the reference address memory 9 stored (active) reference addresses R matches or multiple received Bluetooth addresses B, each with one of the reference address memory 9 stored (active) reference addresses R match.

In an analogous manner, the control information I2 can be output when the comparison device 8th the locking of the lock 3 triggers.

If only a single received Bluetooth address B with one of the in the reference address memory 9 stored (active) reference addresses R, the information block RI1 can be additionally output with. This control information can trigger individual control reactions, such as the setting of a car radio to a specific station, a certain seat adjustment, a specific vehicle mirror adjustment, etc. In this case, the output control information depends on the reference address R, which coincides with the received Bluetooth address B. ,

When unlocking the lock 3 receive multiple Bluetooth addresses B at the same time or almost simultaneously, none of the information RI is output in the simplest case. In this case, it is still possible that the control device 4 via the input device 12 offers a corresponding selection of the received, with one of the active reference addresses R matching Bluetooth addresses B and triggers the output of the corresponding address-dependent control information RI after selecting one of the Bluetooth addresses B by a corresponding input. Alternatively, it is also possible that the reference addresses R are assigned prioritizations P and the output control information RI is determined on the basis of the prioritizations P.

It has been assumed above that the closing device according to the invention 1 is arranged in a motor vehicle. This is also the most common case of use. The locking device according to the invention 1 but could also be arranged in a building.
