Fig. 2 ein Blockschaltbild eines Senders der Diebstahl schutzvorrichtung nach Fig. 1 und Fig. 2 is a block diagram of a transmitter of the theft protection device according to Fig. 1 and
Fig. 3 ein Blockschaltbild eines Empfänger der Diebstahl schutzvorrichtung nach Fig. 1. Fig. 3 is a block diagram of a receiver of the antitheft device of FIG. 1.
Eine Diebstahlschutzvorrichtung für ein Kraftfahrzeug weist einen tragbaren Sender 10 (Fig. 1) auf, der beispielsweise in einer Armbanduhr oder einem Fingerring angeordnet sein kann. Durch den Sender 10 werden Codesignale zu einem Empfän ger 20 im Kraftfahrzeug 2 gesendet (als blitzförmiger Pfeil in der Fig. 1 dargestellt), der die Codesignale auswertet.An anti-theft device for a motor vehicle has a portable transmitter 10 ( FIG. 1), which can be arranged, for example, in a wristwatch or a finger ring. The transmitter 10 sends code signals to a receiver 20 in the motor vehicle 2 (shown as a flashing arrow in FIG. 1), which evaluates the code signals.
Wenn sich die Codesignale als berechtigt erweisen, so wird ein Freigabesignal an ein Sicherheitsaggregat im Kraftfahr zeug ausgegeben. Ein solches Sicherheitsaggregat kann bei spielsweise die Türverriegelung 26, die Motorsteuerung 27 oder die Alarmanlage sein. Somit kann durch die erfindungsge mäße Diebstahlschutzvorrichtung die Funktion eines Schließsy stems, einer Wegfahrsperre und einer Alarmanlage erfüllt wer den.If the code signals prove to be justified, a release signal is issued to a security unit in the motor vehicle. Such a security unit can be, for example, the door lock 26 , the motor control 27 or the alarm system. Thus, the function of a locking system, an immobilizer and an alarm system can be fulfilled by the anti-theft device according to the invention.
Zum Auslösen der Codesignale werden von einem Benutzer 1 ge sprochene Paßworte verwendet. Hierzu werden die gesprochenen Worte von einer Spracherkennungseinheit 12 ausgewertet. Bei Übereinstimmung mit gespeicherten Sollpaßworten wird ein Codesignal erzeugt und ausgesendet.To trigger the code signals from a user 1 ge spoken passwords are used. For this purpose, the spoken words are evaluated by a speech recognition unit 12 . If the stored passwords match, a code signal is generated and transmitted.
Der Aufbau des Senders ist in der Fig. 2 näher erläutert. Der Sender 10 weist einen Codeerzeuger 14 auf, der auf Anfor derung ein Codesignal erzeugt und an ein Sendeelement 16 lie fert. Das Sendeelement 16 sendet das Codesignal über eine Sendeantenne 18 aus. Die Codesignale können optisch, aku stisch oder als Funksignale ausgesendet werden.The structure of the transmitter is explained in more detail in FIG. 2. The transmitter 10 has a code generator 14 , which generates a code signal on request and produces a transmission element 16 lie. The transmission element 16 transmits the code signal via a transmission antenna 18 . The code signals can be emitted optically, acoustically or as radio signals.
Statt einer Taste zum Auslösen des Codesignals wird bei der erfindungsgemäßen Diebstahlschutzvorrichtung die Spracherken nung verwendet. Hierzu weist der Sender 10 ein Mikrofon 11 auf, das ein gesprochenes Paßwort empfängt. In der Spracher kennungseinheit 12 wird das persönliche Sprachmuster des emp fangenen Paßworts ausgewertet und mit einem in einem Paß wortspeicher 13 abgespeicherten Sollpaßwort verglichen. Bei Übereinstimmung mit dem Sollpaßwort wird der Codeerzeuger 14 angewiesen, das Codesignal zu erzeugen. Instead of a button for triggering the code signal, the voice recognition is used in the theft protection device according to the invention. For this purpose, the transmitter 10 has a microphone 11 which receives a spoken password. In the language recognition unit 12 , the personal speech pattern of the received password is evaluated and compared with a target password stored in a password memory 13 . In accordance with the target password, the code generator 14 is instructed to generate the code signal.
Das Paßwort ist ein akustisches, auditives Sprachsignal ei nes Benutzers 1 des Kraftfahrzeugs 2. Es wird durch den Be sitzer oder den berechtigten Benutzer des Kraftfahrzeugs 2 festgelegt. Während einer Initialisierungsphase wird das Paßwort als Sollpaßwort analog oder digital aufgezeichnet und in dem Paßwortspeicher 13 dauerhaft gespeichert.The password is an acoustic, auditory voice signal from a user 1 of the motor vehicle 2 . It is determined by the owner or the authorized user of the motor vehicle 2 . During an initialization phase, the password is recorded as a target password in analog or digital form and is permanently stored in the password memory 13 .
Als gesprochene Paßworte können beispielsweise die Worte "auf", "zu" oder sonstige Phantasieworte verwendet werden. Als Paßwort können auch akustische Laute, einzelne Wörter oder auch ganze Sätze dienen.For example, the words can be used as spoken passwords "auf", "zu" or other fancy words are used. Acoustic sounds, individual words can also be used as a password or serve whole sentences.
Die Paßworte können benutzerabhängig, d. h. nach Phonetik, wie Klangfarbe, Tonhöhe, Sprechrhythmus, usw. oder benutze runabhängig, d. h. nach dem Wortsinn oder dem Bedeutungsinhalt der gesprochenen Worte analysiert werden. Wenn die Paßworte benutzerabhängig ausgewertet werden, so genügt es - bedingt durch geringe Abweichungen in der Sprache, beispielsweise in folge einer Erkältung des Benutzers -, wenn die Paßworte mit den aufgezeichneten Sollpaßworten nur innerhalb einer Tole ranzbreite übereinstimmen. Es können aber auch für den Benut zer 1 charakteristische Sprachmuster in dem Paßwortspeicher 13 abgespeichert sein, mit denen das gesprochene Paßwort verglichen wird. Durch Analyse oder Synthese der gesprochenen Paßworte sowie einem Vergleich mit den Mustern kann dann - bei weitgehender Übereinstimmung - der Codeerzeuger 14 ange wiesen werden, ein Codesignal zu erzeugen.The passwords can be analyzed user-dependently, ie according to phonetics, such as timbre, pitch, speaking rhythm, etc. or use run-dependently, ie according to the sense of the word or the meaning of the spoken words. If the passwords are evaluated depending on the user, it suffices - due to slight deviations in the language, for example as a result of a cold in the user - if the passwords only match the recorded target passwords within a tolerance range. It can also be stored in the password memory 13 for the user zer 1 characteristic speech patterns with which the spoken password is compared. By analyzing or synthesizing the spoken passwords and comparing them with the patterns, the code generator 14 can then be instructed to generate a code signal, if there is broad agreement.
Spracherkennungsmodule mit Sprachanalyse sowie Sprachsynthese sind hinreichend bekannt. Durch sie werden sowohl der Sinn der gesprochenen Worte als auch ihre Phonetik erfaßt. Ihre Funktionsweise braucht daher hier nicht näher erläutert zu werden.Speech recognition modules with speech analysis and speech synthesis are well known. Through it both become the meaning of the spoken words as well as their phonetics. Your Operation does not need to be explained here will.
Sobald der Codeerzeuger 14 angewiesen wird, ein Codesignal zu erzeugen, holt er sich aus einem Codespeicher 15 diverse Da ten, wie beispielsweise einen mathematischen Algorithmus, mit deren Hilfe das Codesignal erzeugt wird. Es kann dabei ein Festcode verwendet werden, bei dem jedesmal das gleiche Code signal ausgesendet wird. Es kann aber auch ein sogenannter Wechselcode oder Rollcode verwendet werden, bei dem sich das Codesignal entsprechend einem Algorithmus nach jedem Aussen den ändert. Das Erzeugen von Codesignalen ist jedoch hinrei chend bekannt und braucht daher nicht näher erläutert zu wer den.As soon as the code generator 14 is instructed to generate a code signal, it fetches various data from a code memory 15 , such as a mathematical algorithm, with the aid of which the code signal is generated. A fixed code can be used, in which the same code signal is sent every time. However, a so-called change code or roll code can also be used, in which the code signal changes according to an algorithm after each outside. However, the generation of code signals is sufficiently known and therefore need not be explained in more detail to who.
Das Sendeelement 16 kann die Codesignale optisch oder aku stisch übertragen. Die Codesignale können aber auch als Funk signale hochfrequent oder niederfrequent übertragen werden.The transmitting element 16 can optically or acoustically transmit the code signals. The code signals can also be transmitted as radio signals high-frequency or low-frequency.
Falls die Spannungsversorgung 19 des Senders 10, die in Form einer Batterie ausgebildet sein kann, unterbrochen ist, oder wenn die Batterie leer ist, so können Energiesignale über ei ne Empfangsspule 17 empfangen werden und zum Erzeugen der Codesignale verwendet werden.If the voltage supply 19 of the transmitter 10 , which may be in the form of a battery, is interrupted, or if the battery is empty, energy signals can be received via a receiver coil 17 and used to generate the code signals.
Der Empfänger 20 (Fig. 3) im Kraftfahrzeug 2 weist ein Emp fangselement 21 auf, das über eine Antenne das Codesignal empfängt. Das Codesignal wird in einem Komparator 22 mit ei nem in einem Sollcodespeicher 23 gespeicherten Sollcodesignal verglichen. Wenn die beiden Signale übereinstimmen, so wird über ein Steuergerät 24 ein Sicherheitsaggregat im Kraftfahr zeug angesteuert.The receiver 20 ( FIG. 3) in the motor vehicle 2 has an receiving element 21 which receives the code signal via an antenna. The code signal is compared in a comparator 22 with a target code signal stored in a target code memory 23 . If the two signals match, a safety unit in the motor vehicle is controlled by a control unit 24 .
Als Sicherheitsaggregate können Türschlösser 26 oder ein Mo torsteuergerät 27 (da optional, ist dies in der Fig. 3 ge strichelt eingezeichnet) dienen. Ebenso können weitere, nicht dargestellte Geräte im Kraftfahrzeug als Sicherheitsaggregate durch das Freigabesignal angesteuert werden, wobei diese Ge räte die Funktion einer Wegfahrsperre, einer Diebstahlschutz anlage oder einer Alarmanlage erfüllen.Door locks 26 or a motor control unit 27 (as optional, this is shown in dashed lines in FIG. 3) can serve as security units. Likewise, other devices, not shown, in the motor vehicle can be controlled as security units by the release signal, these devices performing the function of an immobilizer, an anti-theft system or an alarm system.
Wenn das empfangene Codesignal mit dem Sollcodesignal über einstimmt, so kann eine Anzeigeeinheit 25 angesteuert werden, die optisch oder akustisch anzeigt, daß das Codesignal emp fangen wurde und berechtigt ist, das Sicherheitsaggregat an zusteuern.If the received code signal coincides with the target code signal, a display unit 25 can be activated, which optically or acoustically indicates that the code signal has been received and is authorized to activate the security unit.
Im Kraftfahrzeug ist ferner ein Energiesender 28 vorgesehen, der ein energiereiches Signal über eine Sendespule zu dem in der Nähe befindlichen Sender 10 senden kann. Damit der Ener giesender 28 nicht ständig Energie aussendet und somit die Fahrzeugbatterie zu sehr belastet, ist ein Auslöseschalter 29 vorgesehen, bei dessen Betätigung der Energiesender 28 kurzzeitig sein Energiesignal ausstrahlt. Der Sender 10 kann das Energiesignal nur dann empfangen, wenn er in unmittelba rer Nähe des Energiesenders 28 gebracht wird. Die übertragene Energie reicht aus, um das Codesignal infolge des gesproche nen Paßworts im Sender 10 zu erzeugen.An energy transmitter 28 is also provided in the motor vehicle and can transmit an energy-rich signal to the nearby transmitter 10 via a transmitter coil. A trigger switch 29 is provided so that the energy transmitter 28 does not continuously emit energy and thus places excessive stress on the vehicle battery, upon actuation of which the energy transmitter 28 briefly emits its energy signal. The transmitter 10 can only receive the energy signal if it is brought in the immediate vicinity of the energy transmitter 28 . The transmitted energy is sufficient to generate the code signal as a result of the spoken password in the transmitter 10 .
Bei Störungen der Übertragungsstrecke zwischen dem Sender 10 und dem Kraftfahrzeug 2, kann der Sender 10 in die Nähe des Empfängers 20, d. h. innerhalb eines Bereichs von nur wenigen Metern, gebracht werden und das Kraftfahrzeug 2 kann jeder zeit geöffnet werden.If the transmission path between the transmitter 10 and the motor vehicle 2 is disrupted , the transmitter 10 can be brought close to the receiver 20 , ie within a range of only a few meters, and the motor vehicle 2 can be opened at any time.
Die erfindungsgemäße Diebstahlschutzvorrichtung hat den Vor teil, daß der Sender 10 zum Aussenden des Codesignals für den Benutzer 1 leicht zugänglich ist. Wenn der Sender 10 in einer Armbanduhr angeordnet ist, so kann die Uhr einfach zum Mund geführt und das Paßwort gesprochen werden. Die Spracheingabe hat jedoch nur auslösenden Charakter für die Codesignale. Die Kommunikation mit dem Kraftfahrzeug 2 wird jedoch nur dann eingeleitet, wenn der Benutzer 1 anhand seines Sprachmusters erkannt wurde, oder das Sprachmuster in Form eines Bitmusters an das Kraftfahrzeug 2 zur Identifikation weitergeleitet wird.The anti-theft device according to the invention has the part before that the transmitter 10 for sending out the code signal for the user 1 is easily accessible. If the transmitter 10 is arranged in a wristwatch, the watch can simply be brought to the mouth and the password can be spoken. However, the voice input has only a triggering nature for the code signals. However, communication with the motor vehicle 2 is only initiated if the user 1 was recognized on the basis of his speech pattern, or the speech pattern is forwarded to the motor vehicle 2 in the form of a bit pattern for identification.
