Description

Technical Field

[0001] The present application relates to the field of vehicle communication technology, and in particular to a login method, a login device and a vehicle. Background Art

[0002] Currently, from a security perspective, the first login to the vehicle's onboard application (APP) requires the user to open the QR code scanning page on the vehicle's onboard application to display the QR code, and then use the scanning function of the digital key application (APP) in the mobile terminal to scan the QR code displayed on the vehicle's onboard application. After the code is scanned successfully, the vehicle login authorization request code is obtained, and the vehicle login authorization request code is entered into the digital key application to complete the authentication of the digital key application.

[0003] Later, when the user brings the mobile terminal close to the vehicle, the vehicle determines whether the digital key application of the mobile terminal has been authenticated. If it has been authenticated, the user is authorized to log in to the vehicle application. If it has not been authenticated, the user is prompted that the vehicle application login has failed.

[0004] Considering that this is the first time for the user to use the car application, before the user scans the QR code, the user has not completed the authentication of the digital key application. Therefore, the vehicle will inevitably prompt the user that the car application login failed, resulting in a poor first-time car experience. Summary of the invention

[0005] The embodiments of the present application provide a login method, a login device and a vehicle, so as to realize seamless login of vehicle-mounted computer applications, thereby improving the user's vehicle-using experience.

[0006] In the first aspect, the embodiment of the present application provides a login method, which can be applied to a vehicle, a module in a vehicle (such as a circuit, a chip or a chip system, etc.), or a logical node, a logical module or software that can realize all or part of the vehicle functions.

[0007] Based on the above scheme, when the vehicle receives the user ID from the mobile terminal and determines that the user ID is not in the user ID history record table, indicating that the user ID has not logged in to the vehicle application, the vehicle actively sends a vehicle login authorization request code to the mobile terminal, so that the mobile terminal uses the vehicle login authorization request code to complete the authentication of the digital key application, and then the mobile terminal informs the vehicle through an indication message that the authentication of the digital key application has been completed. The vehicle can then use the user ID to log in to the vehicle application, realizing a seamless login to the vehicle application, eliminating the process of the user using the digital key application to scan the QR code of the vehicle application, and avoiding the problem of failure caused by the user's first login to the vehicle application, thereby improving the user experience.

[0042] Figure 1 1 is a schematic diagram of a login system architecture applicable to the present application. The login system includes a server and a vehicle. Optionally, the login system also includes a mobile terminal.

[0043] The server and the vehicle, the server and the mobile terminal, and the mobile terminal and the vehicle can communicate through mobile communication networks (such as the fifth generation (5th generation, 5G) communication network or future communication network) or wireless local area networks (wireless local area networks, WLAN), etc., or can also communicate through short-range communication technology. In the embodiment of the present application, short-range communication technology may include technology that supports wireless short-range communication. Wireless short-range communication includes the communication parties transmitting information through radio waves and the transmission distance is within a short range (such as within 100 meters), which can be called short-range wireless communication, including but not limited to Bluetooth technology, wireless fidelity (wireless fidelity, Wi-Fi) technology, near field communication (near field communication, NFC) technology, Wi-Fi Aware technology, sound wave communication technology, universal short-range communication technology, short-range communication technology specified by the Star Alliance, etc.

[0044] The server can be a single server or a server cluster composed of multiple servers. For example, it can be a server cluster in which multiple servers are deployed through a distributed architecture. The server cluster may include one or more cloud computing servers, content delivery network (CDN) servers, domain name system (DNS) servers, etc. The servers can coordinate with each other to jointly complete computing, data storage, communication and other functions. For the convenience of description, single servers, distributed servers, server clusters, etc. are collectively referred to as servers in this application. Furthermore, the server can be a physical device, or it can be a virtual machine or container deployed on the cloud.

[0045] The mobile terminal may be used for short-range communication with the vehicle (eg, Bluetooth communication, acoustic wave communication, NFC communication, etc.), and the mobile terminal may be, for example, a mobile phone, a tablet computer, or a laptop computer.

[0046] It should be noted that the above Figure 1 The forms and quantities of the servers, vehicles, and mobile terminals shown are for example only and do not constitute a limitation to the present application.

[0047] Figure 2 A possible application scenario diagram provided for this application. Figure 1 The server, vehicle, and mobile terminal in the example are respectively a cloud server 201, a vehicle 202, and a mobile phone 203.

[0048] The vehicle 202 may be any type of vehicle, such as a smart car, an electric car, a digital car, a sedan, a truck, a motorcycle, a bus, a lawn mower, an entertainment vehicle, an amusement park vehicle, construction equipment, a tram, or a golf cart, etc., and the present application does not limit this. Exemplarily, the vehicle 202 includes a gateway (GW), a hardware and software integrated platform for supporting intelligent driving, i.e., a vehicle computing platform (vehicle computing platform), such as a mobile data center (mobiledata center, MDC), a human-machine interaction system (human-machine interaction, HMI), a telematics control unit (telematics control unit, TCU), a car box (telematics box, Tbox), an electronic control unit (electronic control unit, ECU), etc. One or more components. The GW is a core component in the electronic and electrical architecture of the whole vehicle. As the data interaction hub of the whole vehicle network, it can route network data such as the controller area network (CAN), the local interconnect network (LIN), and the media oriented system transport (MOST) network in different networks. MDC is the vehicle's intelligent onboard computing platform, and MDC can be used to implement the vehicle's autonomous driving function. HMI is the vehicle's infotainment system. TCU and Tbox are mainly used to communicate with vehicle external devices (such as the cloud, fleet owners, etc.), backend systems, etc. ECU is a vehicle-specific microcomputer controller, and ECU includes but is not limited to a vehicle integrated / intergration unit (VIU), a cockpit domain controller (CDC), and a vehicle domain controller (VDC). It should be noted that the upgrade required in this application may include but is not limited to any one or more of the above-mentioned GW, MDC, HMI, TCU, Tbox, and ECU. In addition, the vehicle 202 may also include an operating system, navigation software, map software, monitoring software, and the like.

[0049] It should be noted that the system architecture and application scenarios described above are intended to more clearly illustrate the technical solution of the present application and do not constitute a limitation on the technical solution provided by the present application.

[0050] Currently, from a security perspective, the first login to the vehicle application requires the user to open the code scanning page on the vehicle application to display the QR code, and then use the scanning function of the digital key application in the mobile terminal to scan the QR code displayed on the vehicle application. After the code is scanned successfully, the vehicle login authorization request code is obtained, and the vehicle login authorization request code is entered into the digital key application to complete the authentication of the digital key application. After completing the authentication of the digital key application, the vehicle application can allow the user to log in to the vehicle application.

[0051] Combine the following Figure 3 This section describes the first login process for the vehicle computer application.

[0052] Figure 3 A schematic diagram of the process of first login of a vehicle application provided in an embodiment of the present application. The method comprises the following steps:

[0053] Step 301: When a user uses a vehicle for the first time, the user opens a vehicle application on the vehicle screen.

[0054] In step 302, the vehicle-machine application calls the vehicle-cloud interface to obtain the vehicle login authorization request code from the server, generates a QR code based on the vehicle login authorization request code, and displays the QR code on the vehicle-machine application.

[0055] Step 303: The user opens the digital key application on the mobile terminal and activates the code scanning function to scan the QR code displayed by the vehicle computer application.

[0056] Step 304: After scanning the QR code, the digital key application obtains the vehicle login authorization request code and inputs the vehicle login authorization request code into the digital key application to complete the authentication of the digital key application. The mobile terminal then sends an indication message to the server, which is used to indicate that the mobile terminal has completed the authentication of the digital key application.

[0057] Step 305, the vehicle application queries the server for user information. The server confirms that the mobile terminal has completed the authentication of the digital key application, and then sends the user information to the vehicle application. The user information includes a user ID and a user token. The user ID is used to uniquely identify the user who logs in to the digital key application, and the user token is a temporary user identity identifier. The vehicle can use the user token to access the user's information stored on the server. The vehicle application can use the user ID to log in to the vehicle application. The vehicle application records the user ID in the user ID history record table, which is used to indicate the user who has successfully logged in to the vehicle application on the vehicle.

[0058] Step 306: Subsequently, when the mobile terminal approaches the vehicle, the digital key application sends the user identification to the digital key microcontroller unit (MCU) in the digital key controller via the digital key Bluetooth chip in the digital key controller.

[0059] Step 307 , the digital key MCU sends the user ID to the vehicle application. The vehicle application confirms that the user ID is recorded in the user ID history record table, and then uses the user ID to log in to the vehicle application.

[0060] Considering that the user is using the car machine application for the first time, the user has not completed the authentication of the digital key application before scanning the QR code, so the vehicle will inevitably prompt the user that the car machine application login failed (for example, the prompt method is as follows Figure 4 As shown in the figure, the user’s first car experience is poor.

[0061] In view of the above problems, the present application provides a login method. The login method can realize the seamless login of the vehicle computer application, thereby improving the user's car experience.

[0062] The login method provided by this application can be applied to the above Figure 1 In the login system shown in FIG. 1 , the server, vehicle, and mobile terminal in the login method described below may be the above-mentioned Figure 1 Servers, vehicles, and mobile terminals in the system.

[0063] The following is a further introduction to the login method and device in conjunction with the accompanying drawings. It can be understood that the present application uses a server, a vehicle, and a mobile terminal as examples of the execution subject of the interactive diagram, but the present application does not limit the execution subject of the interactive diagram. For example, the method executed by the server in the present application can also be implemented by a module in the server (such as a circuit, a chip or a chip system, etc.), or a logical node, a logical module, or software that can realize all or part of the server function. The method executed by the vehicle in the present application can also be implemented by a module in the vehicle (such as a circuit, a chip or a chip system, etc.), or a logical node, a logical module, or software that can realize all or part of the vehicle function. The method executed by the mobile terminal in the present application can also be implemented by a module in the mobile terminal (such as a circuit, a chip or a chip system, etc.), or a logical node, a logical module, or software that can realize all or part of the mobile terminal function.

[0064] Figure 5(a) is a flow chart of a login method provided in an embodiment of the present application. The method comprises the following steps:

[0065] Step 501a: After the vehicle and the mobile terminal establish a Bluetooth encrypted transmission channel, the mobile terminal sends a user identification to the vehicle through the Bluetooth encrypted transmission channel. Correspondingly, the vehicle receives the user identification from the mobile terminal.

[0066] The user ID is used to uniquely identify the logged-in user of the digital key application on the mobile terminal.

[0067] The Bluetooth encrypted transmission channel is established based on a one-to-one session key. For example, a session key is negotiated between the mobile terminal and the vehicle's digital key controller, and the session key is used to establish a Bluetooth encrypted transmission channel between the mobile terminal and the vehicle. Unless otherwise specified, the subsequent communication content between the mobile terminal and the vehicle in this application will be encrypted and transmitted using the session key.

[0068] Optionally, after establishing the Bluetooth encrypted transmission channel, the vehicle also obtains a digital key identifier from the mobile terminal, the digital key identifier is used to identify the digital key application of the mobile terminal, the digital key identifier contains information of the mobile terminal, and the information of the mobile terminal can be used to identify the mobile terminal. The information of the mobile terminal includes one or more of the following information: the identifier of the mobile terminal, the user identifier, or the mobile phone number associated with the mobile terminal.

[0069] Step 502a: The vehicle determines whether the user identification is in the user identification history record table.

[0070] The user identification history record table is used to indicate the users who have successfully logged into the vehicle-mounted application on the vehicle. For example, the user identification history record table includes the user identifications of the users who have successfully logged into the vehicle-mounted application on the vehicle.

[0071] Step 503a: If the user ID is not in the user ID history record table, the vehicle sends a vehicle login authorization request code to the mobile terminal via a Bluetooth encrypted transmission channel. Correspondingly, the mobile terminal receives the vehicle login authorization request code.

[0072] The vehicle login authorization request code is used to authenticate the digital key application of the mobile terminal.

[0073] This application does not limit the specific implementation method for a vehicle to obtain a vehicle login authorization request code. As examples, two different implementation methods are given below.

[0074] Implement method A and obtain the vehicle login authorization request code from the vehicle's memory.

[0075] Based on this implementation method, the vehicle login authorization request code is stored locally in the vehicle, so the vehicle login authorization request code can be obtained locally.

[0076] To implement method B, the vehicle obtains a vehicle login authorization request code from the server.

[0077] For example, the vehicle sends a request message to the server, and the request message is used to request a vehicle login authorization request code. Based on the request message, the server sends the vehicle login authorization request code to the vehicle.

[0078] Step 504a, after the mobile terminal inputs the vehicle login authorization request code into the digital key application, it sends instruction information to the vehicle through the Bluetooth encrypted transmission channel. Correspondingly, the vehicle receives the instruction information.

[0079] Among them, after the mobile terminal enters the vehicle login authorization request code into the digital key application, it means that the authentication is successful.

[0080] The indication information is used to indicate that the mobile terminal has completed the authentication of the digital key application, and the indication information is used to trigger the vehicle to use the user identification to log in to the vehicle application.

[0081] Step 505a: The vehicle logs into the vehicle application using the user ID according to the instruction information.

[0082] Based on the above scheme, when the vehicle receives the user ID from the mobile terminal and determines that the user ID is not in the user ID history record table, indicating that the user ID has not logged in to the vehicle application, the vehicle actively sends a vehicle login authorization request code to the mobile terminal, so that the mobile terminal uses the vehicle login authorization request code to complete the authentication of the digital key application, and then the mobile terminal informs the vehicle through an indication message that the authentication of the digital key application has been completed. The vehicle can then use the user ID to log in to the vehicle application, realizing a seamless login to the vehicle application, eliminating the process of the user using the digital key application to scan the QR code of the vehicle application, and avoiding the problem of failure caused by the user's first login to the vehicle application, thereby improving the user experience.

[0083] Figure 5(b) is a flow chart of a login method provided in an embodiment of the present application. The method comprises the following steps:

[0084] Step 501b: After the vehicle and the mobile terminal establish a Bluetooth encrypted transmission channel, the mobile terminal sends a user identification to the vehicle through the Bluetooth encrypted transmission channel. Correspondingly, the vehicle receives the user identification from the mobile terminal.

[0085] The user ID is used to uniquely identify the logged-in user of the digital key application on the mobile terminal.

[0086] The Bluetooth encrypted transmission channel is established based on a one-to-one session key. For example, a session key is negotiated between the mobile terminal and the vehicle's digital key controller, and the session key is used to establish a Bluetooth encrypted transmission channel between the mobile terminal and the vehicle. Unless otherwise specified, the subsequent communication content between the mobile terminal and the vehicle in this application will be encrypted and transmitted using the session key.

[0087] Optionally, after establishing the Bluetooth encrypted transmission channel, the vehicle also obtains a digital key identifier from the mobile terminal, the digital key identifier is used to identify the digital key application of the mobile terminal, the digital key identifier contains information of the mobile terminal, and the information of the mobile terminal can be used to identify the mobile terminal. The information of the mobile terminal includes one or more of the following information: the identifier of the mobile terminal, the user identifier, or the mobile phone number associated with the mobile terminal.

[0088] Step 502b: The vehicle determines whether the user identification is in the user identification history record table.

[0089] The user identification history record table is used to indicate the users who have successfully logged into the vehicle-mounted application on the vehicle. For example, the user identification history record table includes the user identifications of the users who have successfully logged into the vehicle-mounted application on the vehicle.

[0090] Step 503b: If the user identification is not in the user identification history record table, the vehicle sends the mobile terminal information and the first indication information to the server. Correspondingly, the server receives the mobile terminal information and the first indication information.

[0091] The first indication information is used to instruct sending a vehicle login authorization request code to the mobile terminal, and the vehicle login authorization request code is used to authenticate the digital key application of the mobile terminal.

[0092] Optionally, the information of the mobile terminal is carried in the digital key identifier, that is, the vehicle sends the digital key identifier and the first indication information to the server.

[0093] As an implementation method, before the vehicle sends the mobile terminal information and the first indication information to the server, it is determined that a Bluetooth encrypted transmission channel cannot be established between the mobile terminal and the vehicle (for example, the vehicle and the mobile terminal are far apart, the vehicle Bluetooth function fails or is turned off, or the mobile terminal Bluetooth function fails or is turned off). That is, if the vehicle cannot send the vehicle login authorization request code to the mobile terminal through the Bluetooth encrypted transmission channel, the vehicle sends the mobile terminal information and the first indication information to the server to trigger the server to send the vehicle login authorization request code to the mobile terminal.

[0094] Step 504b: the server sends a vehicle login authorization request code to the mobile terminal. Correspondingly, the mobile terminal receives the vehicle login authorization request code.

[0095] The server determines, based on the information of the mobile terminal, that the sending object is the mobile terminal indicated by the information of the mobile terminal, and then sends the vehicle login authorization request code to the mobile terminal.

[0096] Step 505b: After the mobile terminal inputs the vehicle login authorization request code into the digital key application, it sends the second indication information to the server. Correspondingly, the server receives the second indication information.

[0097] Among them, after the mobile terminal enters the vehicle login authorization request code into the digital key application, it means that the authentication is successful.

[0098] The second indication information is used to indicate that the mobile terminal has completed the authentication of the digital key application, and the second indication information is used to trigger the vehicle to use the user identification to log in to the vehicle application.

[0099] Step 506b: The server sends the second indication information to the vehicle. Correspondingly, the vehicle receives the second indication information.

[0100] Step 507b: The vehicle logs into the vehicle application using the user identification according to the second instruction information.

[0101] Based on the above scheme, when the vehicle receives a user ID from a mobile terminal and determines that the user ID is not in the user ID history record table, indicating that the user ID has not logged in to the vehicle application, the vehicle actively instructs the server to send a vehicle login authorization request code to the mobile terminal, so that the mobile terminal uses the vehicle login authorization request code to complete the authentication of the digital key application. The mobile terminal then informs the vehicle through an indication message that the authentication of the digital key application has been completed, and the vehicle can then use the user ID to log in to the vehicle application, realizing a seamless login to the vehicle application, eliminating the process of the user using the digital key application to scan the QR code of the vehicle application, and avoiding the problem of failure caused by the user's first login to the vehicle application, thereby improving the user experience.

[0102] Given below Figure 6 and Figure 7 Two specific examples are specific implementations of the embodiments of FIG. 5( a) or FIG. 5( b) above.

[0103] Figure 6 A flowchart of a login method provided in an embodiment of the present application. The method comprises the following steps:

[0104] Step 601: The user brings the mobile terminal close to the vehicle, and the digital key application in the mobile terminal establishes a Bluetooth encrypted transmission channel with the vehicle.

[0105] Step 602: The digital key application sends a user identification to the digital key MCU via the digital key Bluetooth chip.

[0106] Step 603: The digital key MCU sends the user identification to the vehicle application.

[0107] Step 604 : The vehicle computer application determines whether the user ID is in the user ID history record table.

[0108] Step 605: When the user identifier is not in the user identifier history record table, the vehicle computer application sends the first indication information and the user identifier to the digital key MCU.

[0109] The first indication information is used to instruct the server to send a vehicle login authorization request code to the mobile terminal.

[0110] Step 606: The digital key MCU searches for the corresponding digital key identifier according to the user identifier, and sends the digital key identifier and the first indication information to the Tbox, wherein the digital key identifier includes the information of the mobile terminal.

[0111] Step 607, Tbox sends the digital key identifier and the first indication information to the server.

[0112] Step 608: The server searches for the corresponding mobile terminal according to the digital key identifier and sends a first message to the digital key application of the mobile terminal. The first message includes the digital key identifier and a vehicle login authorization request code.

[0113] In step 609, the mobile terminal launches the digital key application based on the received first message, and then the digital key application determines whether the received digital key identification is consistent with the locally stored digital key identification. If they are consistent, the vehicle login authorization request code is input into the digital key application, and then the second indication information is sent to the server.

[0114] The second indication information is used to indicate that the mobile terminal has completed the authentication of the digital key application, and the second indication information is used to trigger the vehicle to use the user identification to log in to the vehicle application.

[0115] Step 610: The server sends a second indication message to the vehicle application.

[0116] The second indication information is used to indicate that the mobile terminal has completed the authentication of the digital key application, and the second indication information is used to trigger the vehicle to log in to the vehicle application using the user identification. The vehicle logs in to the vehicle application using the user identification according to the second indication information.

[0117] Figure 7 A flowchart of a login method provided in an embodiment of the present application. The method comprises the following steps:

[0118] Step 701 to step 704 are the same as above. Figure 6 Steps 601 to 604 in the embodiment of the present invention.

[0119] Step 705: When the user ID is not in the user ID history record table, the vehicle application sends a vehicle login authorization request code and the user ID to the digital key MCU.

[0120] Among them, the vehicle computer application can obtain the vehicle login authorization request code from the vehicle's memory, or obtain the vehicle login authorization request code from the server.

[0121] Step 706, the digital key MCU searches for the corresponding digital key identifier according to the user identifier, and sends the digital key identifier and the vehicle login authorization request code to the short-range sensor in the digital key controller. The digital key identifier includes the information of the mobile terminal.

[0122] Step 707: The short-range sensor sends a first message to the digital key application of the mobile terminal, the first message including the digital key identification and the vehicle login authorization request code. The short-range sensor may send the first message via Bluetooth, NFC, or sound waves.

[0123] In step 708, the mobile terminal launches the digital key application based on the received first message, and then the digital key application determines whether the received digital key identifier is consistent with the locally stored digital key identifier. If they are consistent, the vehicle login authorization request code is input into the digital key application, and an indication message is sent to the short-range sensor.

[0124] The indication information is used to indicate that the mobile terminal has completed the authentication of the digital key application, and the indication information is used to trigger the vehicle to log in to the vehicle application using the user identification. The vehicle logs in to the vehicle application using the user identification according to the indication information.
