Description

Technical Field

[0001] The present method relates to a method for establishing a communication connection between a new vehicle key and a vehicle. The present invention particularly relates to a system for executing the proposed method.

Background Art

[0002] From German Patent Application Publication No. 102012012389 and German Patent Application Publication No. 102016201601, an apparatus for controlling access authorization and / or driving authorization for a vehicle, or a method for teaching a vehicle key to a vehicle, is known.

Summary of the Invention

Problems to be Solved by the Invention

[0003] With the introduction of digital vehicle keys, the requirements for conventional physical vehicle keys and the characteristics of vehicle keys as an essential element of user / vehicle interaction have changed fundamentally. Previously, it was common to equip a vehicle with a single key pair, and the vehicle user received this key pair by handover at the time of vehicle delivery. If the key was lost or damaged, a spare key was ordered, and this spare key was "taught" to the vehicle, that is, connected so as to be able to communicate, using a diagnostic tester or a key programming device in the learning process by an authorized repair shop. However, a visit to the repair shop means additional time and financial waste for the vehicle user, which is not desirable from the perspective of customer comfort.

[0004] Therefore, an object of the present invention is to provide an improved embodiment or at least one alternative embodiment for a method for establishing a communication connection between a new vehicle key and a vehicle. In particular, a system capable of executing the proposed method must be provided.

Means for Solving the Problems

[0005] In this invention, this objective is addressed particularly by the subject matter of the independent claims. Advantageous embodiments are described in the dependent claims and specification.

[0006] For this purpose, a method has been proposed for establishing a communication connection between a new car key and a vehicle, which can also be called a pairing method. In this method, first, a mobile communication device equipped with a storage medium, such as a mobile phone (smartphone) or other mobile device (e.g., an iPad), a programmable vehicle key that is communicated to the vehicle, and a programmable new car key that is communicatively connected to the vehicle are provided. Here, it will be obvious to those skilled in the art that the new car key is not yet connected to the vehicle at this point, but is only set up for such connection. The vehicle key and the new car key may be programmed via, for example, a wireless key communication interface of the vehicle's electronic ignition switch. The new car key can be easily configured in terms of technology and design, and may be implemented as, for example, an NFC card. Furthermore, a learning application, i.e., a learning program, is provided, which has a user application that can be executed by the user and is provided on the storage medium of the mobile communication device, and an executable backend application that is provided in the vehicle backend and is wirelessly communicated with the mobile communication device and / or the vehicle. The vehicle backend can be understood as the vehicle manufacturer's server environment, which is provided for the purpose of delivering the learning application and, as needed, providing further services and functions for the vehicle. Furthermore, the backend application is configured to provide, or enable, digital authorization to connect the new car key to the vehicle to the user. In the proposed method, the user of the communication device, particularly the authorized dealer of the new car key, registers for use of the learning application, i.e., logs in, using the user application by entering personal data, particularly username and password. Next, the user initiates the key connection process. This key connection process is conveniently provided by the vehicle's infotainment system and / or initiated by the user using the vehicle infotainment system's user communication interface. The following points are important:In other words, within the key connection process, for example, using a learning application. 1) The system verifies whether the user is inside the vehicle and whether digital permission has been granted to the user to connect the vehicle and the new car key in the backend application. Furthermore, this process also verifies whether the user is registered (logged in) to the learning application. If the login is successful, the user's ID can be confirmed. 2) The vehicle's new car key is verified. This verification can be done wirelessly, for example, via the vehicle's transponder interface using a mobile communication device, if necessary. 3) The vehicle key is verified to determine if it is inside the vehicle. This verification can be performed wirelessly if necessary.

[0007] If the verification of conditions 1) to 3) is completed successfully, in this method, the new car key is connected to the vehicle via communication during the coupling process.

[0008] The method proposed here can be performed, for example, directly by the legitimate user (e.g., the seller) when acquiring a new car key. Advantageously, this eliminates the need for additional technical equipment such as diagnostic testers or key programming devices, thus eliminating the need for visits to a repair shop and improving customer convenience. Overall, this allows for a simple and smooth connection between the new car key and the vehicle.

[0009] In the proposed method, it is convenient that during the coupling process, key programming data for connecting the new car key and the vehicle is generated by the vehicle backend and provided to the vehicle. Next, the vehicle provides the acquired key programming data to the new car key, thereby establishing a communication connection between the new car key and the vehicle based on the key programming data, and making the vehicle usable with the new car key. This communication connection may be realized, for example, by transponder communication. This allows the vehicle key to be easily and securely connected to the vehicle.

[0010] Furthermore, it is preferable that the key connection process be initiated by the user using the user communication interface of the vehicle's infotainment system. It is preferable that the proposed method or key connection process is deactivated, i.e., unavailable, in the vehicle's standard mode. However, a user, such as an authorized dealer of a new car key or an authorized service center, can activate the proposed method or key connection process before performing the proposed method, particularly via a telematics service that communicates with the vehicle. Once the connection of the new car key to the vehicle is successfully completed, the proposed method or key connection process can be deactivated either manually or automatically.

[0011] The user communication interface for the vehicle infotainment system may preferably be implemented as a screen (e.g., a touchscreen). The user communication interface is located, for example, in the vehicle's cabin, and is easily accessible and visible to the vehicle's user. In this case, it is convenient if the proposed method or the user communication interface for key connection processing displays an icon visible to the user, and the proposed method or key connection processing can be initialized / started by operating that icon. Of course, if the execution of the proposed method or key connection processing is deactivated, this icon will not be displayed to the user.

[0012] In the proposed method, during the verification of condition 1) mentioned above, it is convenient that the vehicle's infotainment system is used to provide an authentication request, along with the vehicle's VIN, to a telematics application provided to the vehicle backend. Next, after receiving the authentication request, the telematics application generates a random authentication code (e.g., a QR code) with a unique authentication identifier, such as a UUID (Universally Unique Identifier). The generated authentication code and the vehicle's VIN are then assigned to each other by the telematics application and stored as an authentication data package in the vehicle backend or the telematics application's database. Subsequently, the telematics application provides this authentication code to the vehicle's infotainment system. At this time, the vehicle's infotainment system has a user communication interface for the user, and the authentication code is provided to and displayed on the user communication interface. The displayed authentication code is provided to a mobile communication device, for example, by a scanning process performed by the user using a mobile communication device, and this mobile communication device provides the authentication code to the user application. At this time, the user application provides the authentication code along with the user session identifier to the backend application. Next, the backend application provides the authentication identifier of the authentication code to the telematics application to perform authentication. At this time, the telematics application verifies whether the authentication identifier of the authentication code provided by the backend application is valid by searching its database for an authentication data package that has an authentication identifier that matches the authentication identifier provided by the backend application. If an authentication data package with a matching authentication identifier is found, the authentication identifier of the authentication code is valid.Once authentication is successfully completed, the telematics application provides the vehicle's vehicle identification number to the backend application, which verifies that the user is inside the vehicle and that the backend application has granted the user digital authorization to connect the new car key to the vehicle. This process confirms that a legitimate user (e.g., the seller) is actually inside the vehicle to establish a communication connection between the new car key and the vehicle. Furthermore, this allows the backend application to verify whether the user has been granted digital authorization to connect the new car key to the vehicle. This authorization to connect the new car key may be granted, for example, by the vehicle manufacturer.

[0013] During the verification of condition 2) mentioned above, it is even more convenient if the key identifier of the new car key inside the vehicle can be read from the new car key using the key communication interface of the vehicle's electronic ignition switch. In this case, the key identifier of the new car key and the vehicle identification number of the vehicle are provided to the telematics application provided to the vehicle backend, and the telematics application provides the key identifier of the new car key along with the vehicle identification number of the vehicle to the backend application. This confirms that the new car key is inside the vehicle, which is essential for establishing a communication connection between the new car key and the vehicle.

[0014] In the proposed method, during the verification of condition 3) described above, it is convenient that a key existence query is sent to a telematics application provided to the vehicle backend using a key data management application provided to the vehicle backend. At this time, the telematics application sends the key existence query to the key communication interface of the vehicle's electronic ignition switch, the ignition switch detects and identifies the vehicle key, for example wirelessly, and generates existence information, the ignition switch provides this existence information along with the vehicle's vehicle identification number to the telematics application, the telematics application provides this existence information along with the vehicle's vehicle identification number to the key data management application, where the existence information is verified. This confirms that the vehicle key is present in the vehicle, which is essential for establishing a communication connection between the new vehicle key and the vehicle.

[0015] In the proposed method, particularly during key connection processing, the mobile communication device may be configured to communicate wirelessly with the vehicle via the vehicle's infotainment system's communication interface. This makes communication between the mobile communication device and the vehicle relatively easy to achieve.

[0016] In the key connection process, it is advantageous if the new car key and / or the vehicle key communicate wirelessly with the vehicle via the key communication interface of the vehicle's electronic ignition switch. This makes communication between the new car key and / or the vehicle key and the vehicle relatively easy to achieve.

[0017] Furthermore, it is advantageous when a mobile communication device and / or a vehicle's infotainment system communicates wirelessly with the vehicle's backend via a mobile radio network. This makes communication between the communication device and / or the vehicle's infotainment system and the vehicle's backend relatively easy to implement.

[0018] According to another fundamental idea of ​​the present invention, a system is provided for carrying out the method described above. This system comprises a vehicle, a vehicle backend assigned to the vehicle, a mobile communication device having a storage medium, such as a mobile phone (smartphone) or other mobile device (e.g., iPad), a programmable vehicle key connected to the vehicle, and a programmable new car key that can be connected to the vehicle. It will be obvious to those skilled in the art that the new car key is not yet connected to the vehicle at this point, but is only set up for such connection. Furthermore, the system has a learning application, i.e., a connection program, which comprises an executable user application provided on the storage medium of the mobile communication device and an executable backend application provided in the vehicle backend and wirelessly connected to the mobile communication device. Furthermore, the vehicle has an electronic ignition switch with a key communication interface for communicating with the vehicle key and the new car key, and a vehicle infotainment device with a user communication interface for communicating with the user, and the vehicle backend is configured to have a telematic application with a database and a key data management application in addition to the backend application. This provides an advantageous system capable of carrying out the proposed method.

[0019] In summary, this method relates to a method for establishing a communication connection between a new car key and a vehicle, and in this method, a learning application is used during the key connection process. 1) It is verified whether the user is inside the vehicle and whether the user has been given digital permission to connect the vehicle and the new car key in the backend application of the learning application. 2) It is verified whether the new car key is inside the vehicle. 3) It is verified whether the vehicle key is inside the vehicle. When the verification of conditions 1) to 3) ends normally, the new vehicle key is communicatively connected to the vehicle in the coupling process. The present invention particularly relates to a system installed for executing the proposed method.

[0020] Even more important features and advantages of the present invention will become apparent from the dependent claims, the drawings, and the corresponding description based on the drawings.

[0021] It should be understood that the features described above, and the features further described below, can be used not only in the combinations shown, without departing from the scope of the present invention, but also in other combinations or alone.

[0022] Preferred embodiments of the present invention are illustrated in the drawings and will be described in more detail below. The same reference numerals represent the same or similar, or functionally identical components.

[0023] Here, the following are schematically described in the drawings respectively.

Modes for Carrying Out the Invention

[0025] Figure 1 shows a method, collectively denoted by reference numeral 1, which is provided for establishing a communication connection between a new car key 6 and a vehicle 4. This method may also be referred to as a pairing method or a method for teaching the new car key 6 to the vehicle 4, without departing from the scope of the present invention. In Method 1, first, a system 21 for performing Method 1 comprises the following peripheral elements, namely: A mobile communication device 2 equipped with a storage medium, such as a mobile phone (smartphone) or other mobile device (e.g., iPad), a programmable vehicle key 5 connected to the vehicle 4 for communication, and a programmable new car key 6 that is not connected to the vehicle 4 for communication but is capable of communicating with the vehicle 4. A conventional vehicle 4 having a passenger compartment 4a for the user, an electronic ignition switch 17 with a key communication interface 18 for communicating with the vehicle key 5 and the new car key 6, and a vehicle infotainment system 13 having a user communication interface 14 that is visible and operable from the passenger compartment 4a, for example, by a screen or touchscreen, for communicating with the user 3 and / or mobile communication device 2, The mobile communication device 2 has an executable user application 8 provided on its storage medium, and an executable backend application 9 provided in the vehicle backend 10, which is wirelessly connected to the mobile communication device 2, and also has a learning application that can be called a connection program. The vehicle backend 10, which is understood to mean the server environment of the vehicle manufacturer of vehicle 4, is assigned to vehicle 4 and includes a backend application 9, a telematics application 15, a database 16 assigned to the backend application 9, and a key data management application 19.

[0026] The mobile communication device 2 can wirelessly communicate with the backend application 9 via the mobile wireless network 20. Similarly, the vehicle infotainment system 13 and the ignition switch 17 can wirelessly communicate with the telematics application 15 via the mobile wireless network 20. For this purpose, the vehicle 4, exemplary, has a telematics control unit 22, which can form a corresponding connection with the telematics application 15 via the mobile wireless network 20, and the telematics application 15 is in communication with the vehicle infotainment system 13 and the ignition switch 17.

[0027] In Method 1, the backend application 9 is configured to provide user 3 with a digital authorization to connect the new car key 6 to the vehicle 4 via the database 16. The database 16 stores the digital authorization, while user application 8 reads and uses this data. Furthermore, user 3 of the communication device 2 registers (logs in) to the learning application using user application 8, for example, by entering personal data (particularly username and password). Next, in Method 1, user 3 initiates the so-called key connection process. This can be achieved by user 3 by, for example, operating a dedicated icon for executing Method 1, which is displayed by the user communication interface 14.

[0028] The important point is that during the key connection process, the following points are verified using the learning application: 1) The system verifies whether user 3 is inside vehicle 4 or inside vehicle 4a, and whether user 3 has been granted digital permission stored in database 16 to connect vehicle 4 and new car key 6 in the backend application 9. Furthermore, it verifies whether the user is registered (logged in) to the learning application. If the login is successful, the user's ID can be determined. 2) It is verified whether the new car key 6 is inside the vehicle 4 or inside the passenger compartment 4a of the vehicle 4. 3) It is verified whether the vehicle key 5 is inside the vehicle 4, preferably inside the passenger compartment 4a.

[0029] Once the verification of conditions 1) to 3) is successfully completed, the new car key 6 is connected to the vehicle 4 in a so-called coupling process.

[0030] During the verification of Condition 1, the vehicle infotainment system 13 first provides an authentication request, along with the vehicle identification number of vehicle 4, to the telematics application 15 provided to the vehicle backend 9 (see arrow A in Figure 1). After receiving the authentication request, the telematics application 15 generates a random authentication code (e.g., a QR code) with a unique authentication identifier, e.g., a UUID (Universally Unique Identifier). Next, the generated authentication code and the vehicle identification number of vehicle 4 are assigned to each other by the telematics application 15 and stored in the telematics application 15 as an authentication data package. Furthermore, the telematics application 15 provides the authentication code to the vehicle infotainment system 13 of vehicle 4 (see arrow B in Figure 1), and the vehicle infotainment system 13 displays the authentication code in the form of a QR code readable by the mobile communication device 2 via the user communication interface 14.

[0031] Next, the displayed authentication code (QR code) is provided to the mobile communication device 2 by a scanning process performed by the mobile communication device 2. In response, the communication device 2 provides the authentication code to the user application 8, which in turn provides the authentication code to the backend application 9 along with the user session identifier (see arrow C in Figure 1). Furthermore, the backend application 9 provides the authentication identifier of the authentication code to the telematics application 15 (see arrow D in Figure 1). Next, the telematics application 15 verifies whether the authentication identifier of the authentication code provided by the backend application 9 is valid by searching for an authentication data package that has an authentication identifier that matches the authentication identifier provided by the backend application 9. The authentication identifier of the authentication code is valid only if an authentication data package with a matching authentication identifier is found. Once authentication is successfully completed, the telematics application 15 provides the vehicle identification number of vehicle 4 to the backend application 9 (see arrow E in Figure 1). This confirms that user 3 is inside vehicle 4 and that user 3 has been granted digital permission in the backend application 9 to connect vehicle 4 with the new car key 6.

[0032] During the verification of condition 2), the key identifier of the new car key 6 located inside the vehicle 4 is read using the key communication interface 18 of the electronic ignition switch 17. Here, the key identifier of the new car key 6 and the vehicle identification number of the vehicle 4 are provided to the telematics application 15 (see arrow F in Figure 1). At this time, the telematics application 15 provides the key identifier of the new car key 6, along with the vehicle identification number of the vehicle 4, to the backend application 9 (see arrow G in Figure 1). This confirms that the new car key 6 is located inside the vehicle 4. This is essential for establishing a communication connection between the new car key 6 and the vehicle 4.

[0033] In the verification of condition 3), a key existence inquiry is sent to the telematics application 15 using the key data management application 19 (see arrow H in Figure 1). At this time, the telematics application 15 sends the key existence inquiry to the key communication interface 18 of the electronic ignition switch 17 (see arrow I in Figure 1). In response, the ignition switch 17 detects the vehicle key 5, for example wirelessly, and at this time, the vehicle key 5 is identified and existence information is generated. Subsequently, the existence information is provided to the telematics application 15 by the ignition switch 17 along with the vehicle identification number of the vehicle 4 (see arrow J in Figure 1). The telematics application 15 provides the existence information along with the vehicle identification number of the vehicle 4 to the key data management application 19 (see arrow K in Figure 1), and the key data management application 19 verifies this existence information. This confirms that the vehicle key 5 is present in the vehicle 4.

[0034] In the coupling process where the new car key 6 is connected to the vehicle 4, key programming data for connecting the new car key 6 and the vehicle 4 is generated by the vehicle backend 10 and provided to the vehicle 4. Specifically, the backend application 9 generates a key programming request and sends it to the key data management application 19 (see arrow L in Figure 1). Based on the verification of condition 3), once it is confirmed that the vehicle key 5 is inside the vehicle 4, the key data management application 19 generates key programming data for the new car key 6 and sends it to the telematics application 15 (see arrow M in Figure 1). The telematics application 15 sends the key programming data to the key communication interface 18 of the ignition switch 17 via the telematics control device 22 (see arrow N in Figure 1). In response, the ignition switch 17 sends the key programming data to the new car key 6, where it can use the key programming data to establish a communication connection between the new car key 6 and the vehicle 4, so that the vehicle 4 can be used by user 3 with this new car key 6. This allows the new car key 6 to communicate and connect with the vehicle 4 easily and securely.
