Description

The The present invention relates to a method of identification a motor vehicle replacement, a corresponding motor vehicle and a corresponding device.

Worldwide The number of manufacturers of counterfeit inferior motor vehicle spare parts is increasing. Such counterfeit motor vehicle spare parts rarely reach the quality the original spare parts and meet sometimes not even the minimum requirements of motor vehicle manufacturers on motor vehicle spare parts. This can be especially true for driving safety affecting automotive spare parts, such as brakes or brake pads, fatal Have consequences.

moreover It is due to the increasingly complex motor vehicles in the premium area required that the interaction of different components a motor vehicle reliable takes place, and the components are coordinated. So is It is advantageous if the control of modern motor vehicle engines on information about Type and / or type of engine oil based. Likewise, when replacing electronic components the knowledge of the software version of co-operating components for one error-free operation of the overall system is of crucial importance be or at least in the correction of defects useful be.

to Identification of goods are currently establishing what is known as RFID (Radio Frequency Identification) - procedure, contactless with identification data and to be able to read and save without visual contact.

One RFID system includes, for example, a radio identification element (Also transponder, RFID tag, chip, tag, RFID tag or chip called) on the identification data items or other information can be stored, one Radio receiving device (also called reading device or reader), a radio transmitter and central control and / or storage devices for the processing, storage and possibly forwarding of the identification data.

The RFID transponders sometimes differ quite a bit from each other. The structure of an RFID transponder, for example, sees an antenna, an analogue circuit for receiving and / or transmitting (transponder), as well as a digital circuit and a permanent memory in front. RFID transponders can use one have multi-writable memory in which during the lifetime Information can be stored.

RFID transponder There are basically two versions: active RFID transponders and passive RFID transponders. Active RFID transponders are battery operated and can typically both read and described. active RFID transponders are normally idle, i. they do not send out information. Only if a special activation signal is received, the transmitter is activated. Passive RFID transponders get their energy to send information from the received Radio waves. The amount of stored data is much lower as with active RFID transponders. In their memory is usually a unique identification number (GUID) deposited. Some passive Transponders are equipped with a rewritable memory.

It It is now an object of the invention to provide a technical teaching, with which a motor vehicle replacement can be reliably identified. These The object is solved by the features of the independent claims. advantageous and appropriate training are in the dependent claims specified. There are also developments of the independent motor vehicle claim and the independent one Device claim within the scope of the invention, which correspond to the dependent method claims.

at a method according to the invention for identifying a motor vehicle replacement means is the motor vehicle replacement assigned a radio identification element. On or in the radio identification element is an authorization object that relates to the vehicle replacement relates, stored. The authorization object is assigned with the assignment, in the assignment or in the course of the assignment of the corresponding Motor vehicle replacement means for a motor vehicle, in particular with a Verbauen of the corresponding motor vehicle replacement in a motor vehicle, sent by the radio identification element and by a radio receiving device associated with the motor vehicle receive.

at The motor vehicle replacement may be any vehicle replacement product, such as an engine oil, a motor vehicle wearing part, a motor vehicle control program, an electronic road map, Brake pads, a vehicle battery, a control unit, a motor vehicle light, etc. or a combination of such products.

The authorization object may include the motor vehicle replacement type, the vehicle replacement name, a serial code, a part code, a storage code, a management code, a manufacturing code, a version number, a manufacturing location, a manufacturing time, a batch code, an installation instruction, a part property, physical parameters, a building instruction, a vehicle setting notice, an identification code, an authorization code, an authorization signal, an authorization message, an authorization key, an authorization bit, an authorization code, a test code, a verification code and / or one or more types of vehicles, for which the motor vehicle substitute is suitable include. Encrypting one or more of these information with a special authorization key can also result in an authorization object.

Preferably is the motor vehicle replacement by a radio identification element associated with that the radio identification element is part of the packaging of the motor vehicle replacement means is that the radio identification element within the packaging of the motor vehicle replacement is that the radio identification element with the packaging of the motor vehicle replacement solvable is connected, that the radio identification element with the motor vehicle replacement solvable or that the radio identification element is part of Accompanying documents or the scope of delivery of the motor vehicle replacement is. The radio identification element is advantageously not firmly connected to the motor vehicle replacement itself, since For example, a fixed attachment of the radio identification element Hardly possible on a brake disc is, or the radio identification element during use of the vehicle would be stressed too much mechanically or thermally.

By the invention is achieved that a motor vehicle replacement easily and reliably identified can be.

Preferably is provided that after receiving the authorization object or as an indirect or immediate reaction to the receipt of the Authorization object, in particular the authorization code and / or the name of the vehicle replacement, automatically a on the Authorization object based information display on a Vehicle associated display device takes place. At the display device acts it is advantageously a display device of the vehicle, which already exists for another purpose anyway. The ad can but also on any display device outside the vehicle, For example, on a PC or a diagnostic device that with the Vehicle communication technology are connected.

Preferably before the information display, the received authorization object, in particular an authorization code or authorization code contained therein, on the vehicle side checked for validity, and if the result is positive, the information shown is also displayed on the authorization object, in particular the name of the motor vehicle substitute, based, triggered. For example, the validity the authorization code are checked by that the received authorization code is present in the vehicle or generable authorization codes. Preferably there is no information display if no authorization object is received or the authorization object, in particular the authorization code, invalid is.

Thereby It will be a fitter, a mechanic, a service technician or the Driver allows easy and comfortable reliable information about to read the installed or to be installed motor vehicle replacement and, for example, the name or type of the motor vehicle replacement to experience.

Especially Preferably, it is provided that based on or together with the Information display queried a vehicle replacement kit shoring confirmation which, for example, by the responsible fitter after the successful shoring of the motor vehicle substitute in the vehicle by means of an anyway in the vehicle already for input device provided for a different purpose or by means of a anyway in the vehicle already for entered a different purpose user interface becomes. Preferably, no vehicle substitute shoring confirmation is requested, if no or invalid Authorization object exists.

at a preferred embodiment is based on an inputted automobile substitute shoring confirmation and / or triggered by the entry of a vehicle replacement kit shoring confirmation and / or automatically a confirmation object based on the authorization object by a radio transmitting device associated with the motor vehicle in particular sent to the radio identification element. The confirmation object preferably includes installation information (installation location, installation time, Mechanic's name), information about the built-in vehicle replacement, information about the Motor vehicle and / or a Sperranweisungsobjekt. Preferably no confirmation object sent when vehicle-side no motor vehicle substitute shoring confirmation entered was and / or not valid Authorization object exists.

With the confirmation object, preferably a vehicle identification object is sent, which in particular is vehicle identification data, such as a vehicle identification code or the chassis number, installation information (installation location, installation time, mechanic name, tool) or information about the installed motor vehicle replacement means. The vehicle identification object can also be part of the confirmation object. Installation site, installation time, tool and / or mechanic name are entered, for example, either in the context of entering the vehicle replacement kit-shoring confirmation or automatically provided on the vehicle side. Information about the installed motor vehicle substitute can originate from the authorization object, and vehicle identification data can be read, for example, from a vehicle-side memory by the complete or partial automatic storage of the confirmation object and / or the vehicle identification object in the radio identification element, preferably in response to the receipt of the confirmation object or the transmission a Sperrbestätigungsobjektes (see below), the completed installation of the motor vehicle replacement means including additional information that describe or identify, for example, the vehicle replacement, the shoring or the vehicle recorded. As a result, the radio-identification element forms a certificate for the fact that a certain motor vehicle substitute has been installed in a certain identifiable vehicle. With this certificate or a large number of corresponding certificates, the vehicle owner can later make warranty claims more valid, or proof the sale of high-quality motor vehicle replacement products during resale. For this purpose, it can be provided that the radio identification element (see below), which is completely or partially blocked for the transmission of the authorization object, is not blocked for the transmission of the vehicle identification object.

Preferably is also an information object on the radio identification element, which describes or characterizes the motor vehicle substitute, stored next to the authorization object to the radio receiving device of the vehicle can be; Preferably, however, it can not be the query of a vehicle replacement kit-Verbau-confirmation and / or sending a confirmation object cause. The information object can also be part of the authorization object. Preferably, the information object can also be blocked of the radio identification element (see below) for the transmission of the authorization object be read from the radio identification element, for example in a sale of the vehicle information about the installation of motor vehicle replacement to get into the vehicle. It can also be alternative or supplementary form part of the said certificate.

Preferably is based on the received by the radio identification element Confirmation object in particular the lock instruction object, or triggered by the confirmation object, in particular the blocking instruction object, the radio identification element for a further transmission of the Authorization object completely or partially blocked, for example the authorization object is wholly or partially deleted, an authorization code deleted or disabled, or the radio identification element in whole or in part destroyed or deactivated.

So it becomes impossible a fake inferior motor vehicle replacement in a to install another vehicle and to install an original motor vehicle the radio identification element and thus the authorization object is assigned to pretend thereby the radio identification element is also assigned to this vehicle In particular, the authorization object is also transmitted to this vehicle. So it can be the installation of an original motor vehicle replacement which can only be done once, even once by the assigned Radio identification element signaled to a vehicle and there be held. As a result, the shoring of an inferior Motor vehicle replacement and concurrent fraudulent Pretend or Billing the construction of a high-quality motor vehicle replacement at least more difficult.

Also This prevents an incompatible or not approved motor vehicle replacement installed in a vehicle and the installation of a compatible or approved motor vehicle the radio identification element and thus the authorization object is associated, thereby simulated is that the wireless identification also assigned to this vehicle In particular, the authorization object is also transmitted to this vehicle becomes.

alternative it is possible to that the radio identification element is not based on the confirmation object for one further transmission the authorization object is blocked, but that the radio identification element automatically after a single transfer or after one one-time transmission of the authorization object for another transmission the authorization object is completely or partially blocked, or that the authorization object is generally sent only once can. After this one-time transmission, the radio identification element for example, completely or partially disabled or automatically be destroyed.

A further alternative embodiment provides that after the complete or partial blocking of the radio identification element for a further transmission of the authorization object au a blocking acknowledgment object is automatically sent from the radio identification element to the radio receiving device.

• – der erfolgte Verbau des Kraftfahrzeugersatzmittels und beispielsweise zusätzliche Informationen, die auf dem Berechtigungsobjekt oder auf dem Informationsobjekt basieren oder aus dem Berechtigungsobjekt oder aus dem Informationsobjekt stammen, werden automatisch in dem Kraftfahrzeug oder einer anderen dem Kraftfahrzeug zugeordneten aber fahrzeugexternen Speichereinrichtung festgehalten oder abgespeichert;
• – eine automatische auf dem Berechtigungsobjekt oder dem Informationsobjekt basierende Anpassung des Fahrzeuges oder eines Steuergerätes des Fahrzeuges an das Kraftfahrzeugersatzmittel. Dadurch wird eine zuverlässige, sichere und komfortable Einstellung des Fahrzeuges ermöglicht. Beispielsweise kann das Motorsteuergerät so mit hoher Zuverlässigkeit und einfach an das eingefüllte Motoröl angepasst werden.
• – eine automatische, insbesondere warnungsfreie, auf dem Berechtigungsobjekt oder Informationsobjekt basierende Zurücksetzung einer Verschleißanzeige oder einer Verschleißermittlungseinrichtung, die sich auf das Kraftfahrzeugersatzmittel bezieht. Beispielsweise verfügen moderne Kraftfahrzeuge über eine Anzeige oder Ermittlung des Verschleißgrades der Bremsbeläge. Diese Anzeige oder Ermittlung funktioniert nur dann zuverlässig, wenn die Bremsbeläge bestimmte Mindestanforderungen erfüllen oder bestimmte Materialien enthalten. Dagegen funktioniert diese Anzeige oder Ermittlung häufig dann nicht zuverlässig, wenn minderwertige Bremsbeläge verbaut werden. Dies kann zu ernsten Sicherheitsproblemen führen, wenn die Anzeige einen besseren Bremsbelagzustand anzeigt als tatsächlich vorliegt. Durch die Zurücksetzung der Verschleißanzeige oder der Verschleißermittlungseinrichtung nur für den Fall des Verbaus geeigneter, geprüfter oder zugelassener Kraftfahrzeugersatzmittel, denen ein entsprechendes Funkidentifikationselement zugeordnet ist, kann dieses Problem vermieden werden.

Depending on the embodiment variant, the input of a motor vehicle replacement kit installation confirmation, the transmission of the confirmation object and / or the receipt of the Sperrbestätigungsobjekts in the motor vehicle automatically trigger one or more of the following steps (because only in these cases, a further transfer of the authorization object is blocked and thus preventing misuse):

• - The completed installation of the motor vehicle substitute and, for example, additional information based on the authorization object or on the information object or come from the authorization object or from the information object are automatically recorded or stored in the motor vehicle or other the vehicle associated with but external to the vehicle storage device;
• - An automatic based on the authorization object or the information object adaptation of the vehicle or a control device of the vehicle to the motor vehicle replacement means. This allows a reliable, safe and comfortable adjustment of the vehicle. For example, the engine control unit can be adapted with high reliability and easy to the filled engine oil.
• - An automatic, in particular warning-free, based on the authorization object or information object resetting a wear indicator or a wear detection device that refers to the motor vehicle replacement. For example, modern motor vehicles have an indication or determination of the degree of wear of the brake pads. This indication or determination works reliably only if the brake pads meet certain minimum requirements or contain specific materials. In contrast, this display or determination often does not work reliably when low-quality brake pads are installed. This can lead to serious safety issues if the display indicates a better brake pad condition than is actually present. By resetting the wear indicator or the wear determining device only in the case of the installation of suitable, tested or approved motor vehicle replacement means, which is associated with a corresponding radio identification element, this problem can be avoided.

alternative or in addition this is after the introduction of a motor vehicle replacement in a vehicle a warning or error-free resetting a wear indicator or a wear detection device depending on the variant then not possible, if no confirmation object of the radio transmitter has been sent to the radio identification element, if no vehicle replacement seal confirmation has been entered, and / or if not a blocking confirmation object was received. For example, resetting the wear indicator Although it may be possible to install an unsuitable motor vehicle but only in connection with the display of a message (warning message), the driver or the fitter on the above problem draws attention.

Especially the invention is practicable when the radio receiving device and / or the radio transmitting device is integrated in the vehicle and / or is part of the vehicle. For example, the Radio receiving device and / or the radio transmitting device in the dashboard or the center console be integrated or adjacent to the glove box be arranged of the vehicle.

advantageously, are the radio receiving device and / or the radio transmitting device set up such that their transmission range or reception range less than the vehicle dimensions to misallocate in a workshop prevent.

Especially preferred are the radio receiving device, the radio transmitting device and the radio identification element is set up such that the Transmission range of the radio identification element or the reception range the radio receiving device is smaller than the transmission range of the Radio transmission device or the reception range of the radio identification element. This can be achieved that, if an authorization object has been shipped, the installation of a motor vehicle replacement has been done and confirmed by the entry of a motor vehicle substitute Verbau confirmation is, also reliable a blocking of another transmission of the authorization object.

This especially applies to the variant without sending a blocking confirmation object.

at the embodiment with sending the revocation confirmation object On the other hand, it is preferably provided that the transmission range of the radio identification element or the reception range of the radio receiving device is greater than the transmission range of the radio transmitter or the reception range of the radio identification element, so that a blocking also to receive a Sperrbestätigungsobjektes the vehicle leads.

When Particularly easy in practical implementation proved, though with the activation of the vehicle, in particular the ignition of the vehicle, automatically in the reception area of the radio receiving device lying Radio identification required by the radio transmitter or their respective authorization object to send.

The information transfer can be protected from tampering that messages, between the radio transmitter and the radio receiver and the radio identification element are exchanged based on the vehicle identification object, in particular the chassis number the vehicle and / or the current mileage of the vehicle, encoded become.

alternative or in addition For this purpose, it may be provided that messages between the radio transmitting device or the radio receiving device and the radio identification element be replaced based on one from the vehicle manufacturer issued key, the vehicle manufacturer and / or the authorized motor vehicle manufacturer is known to be encrypted.

Around a vehicle manufacturer an overview of the To allow for the installation of motor vehicle substitutes in vehicles, is advantageously provided that one on the authorization object or the information object based information transfer from a the vehicle assigned, for example, in anyway existing, data transmission device, such as a cellular module or a wireless module, etc., to a central Establishment of the vehicle manufacturer takes place.

According to one Particularly preferred embodiment is the radio identification element with a self-adhesive adhesive, which is suitable for gluing the wireless identification element in a vehicle service booklet is connected. So can the Advantages of a conventional Service booklet in paper form with the advantages of an electronic service booklet be combined. After the positioning of the vehicle service booklet including the radio identification elements in the reception area of another Radio receiver, which is for example in a workshop or a used car dealer, may be due to the complete or partial transmission of the information objects and / or authorization objects from the respective radio identification elements to the other radio receiving device be determined and displayed, which motor vehicle replacement were installed in a vehicle. This can also be the installation site and / or the installation time will be displayed.
