Description

Technical Field

[0001] This application relates to the technical field of digital car keys, and more particularly to a method, system and readable medium for sharing digital car keys. Background Technology

[0002] Currently, in scenarios where car owners need to share their digital car keys with family and friends, the common practice is for the car owner to apply for a shared key through a mobile app to the OEM's Telematics Service Provider (TSP) platform. After receiving the application, the TSP sends a text message to the family or friend, who then downloads the relevant app provided by the OEM, registers an account, and enters the app to receive the shared Bluetooth key. The family or friend can then use the Bluetooth key to control the vehicle. This process requires the family or friend to download the OEM's app, register an account, and fill in relevant information, which is inconvenient and cannot be reused with the key function built into the phone manufacturer.

[0039] Figure 2 This is a schematic diagram illustrating the specific process of sharing the digital car key according to this application;

[0040] Figure 3 This is a schematic diagram of the digital car key sharing system of this application. Detailed Implementation

[0041] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, provides a detailed account of the specific implementation methods, steps, structures, features, and effects proposed in this application. The following detailed description should not be considered limiting; the terminology and accompanying drawings used herein are merely for describing specific embodiments and are not intended to limit this application.

[0042] Figure 1 This is a flowchart illustrating the digital car key sharing method of this application, as shown below. Figure 1 As shown, this application provides a method for sharing a digital car key, including the following steps:

[0043] Step 110: The first mobile terminal sends a key sharing request to the vehicle's central control server.

[0044] The first mobile terminal is the terminal used by the car owner, including but not limited to mobile phones, smartwatches, etc. When the digital car key needs to be shared with others, the car owner can perform relevant operations on the first mobile terminal to send a key sharing request to the vehicle's server. Specifically, the car owner can log in to the application using their car owner account, find the digital key function, perform relevant operations, and click "Share Digital Key." At this time, the application will send a digital car key sharing request to the vehicle's server.

[0045] A vehicle-mounted server refers to the server used by an automaker to process information related to digital car keys. Different automakers can configure their own vehicle-mounted servers, and of course, a vehicle-mounted server can also serve multiple different automakers simultaneously.

[0046] A key sharing request includes information about the sharer and the recipient. The sharer's information is the vehicle owner's information, which can be the vehicle owner's mobile phone number, IMEI code, or account, etc. The recipient's information is the information of the user who needs the vehicle owner to share the digital car key, which can be a family member or friend's mobile phone number, IMEI code, or account, etc.

[0047] Step 120: The vehicle system server generates key sharing information based on the key sharing request and sends it to the first mobile terminal, so that the first mobile terminal can send the key sharing information to the second mobile terminal.

[0048] Specifically, after receiving a key sharing request, the vehicle-mounted system server generates key sharing information based on the request. This information includes information about the sharing party, the receiving party, and the vehicle-mounted system. The sharing party and receiving party information are as described previously, while the vehicle-mounted system information can be the vehicle's VIN, vehicle-mounted system identifier, etc. In practice, the key sharing information can be in the form of a sharing password. The password consists of two parts, separated by a comma: one part is an encrypted string containing the sharing party and receiving party information; the other part is plaintext containing auxiliary information such as the vehicle-mounted system identifier.

[0049] In one implementation, after receiving a key sharing request, the vehicle system server also verifies the identity of the sharing party based on the sharing party information in the key sharing request. Verification information includes, for example, whether the mobile phone number pre-stored by the vehicle owner matches the mobile phone number that sent the key sharing request, in order to confirm whether the identity is legitimate.

[0050] Optionally, the vehicle-mounted server saves the key-sharing information when generating it. After receiving the key-sharing information from the server, the first mobile terminal sends it to the second mobile terminal. Specifically, both the first and second mobile terminals have instant messaging applications installed, allowing them to share the key-sharing information. For example, after receiving the key-sharing information, the car owner copies it to their phone's clipboard and then sends it to the recipient via instant messaging applications such as WeChat, QQ, or SMS, making the process more convenient.

[0051] Step 130: The second mobile terminal sends the key sharing information to the terminal server;

[0052] Specifically, the first mobile terminal receives key-sharing information sent by the car owner's contact through installed instant messaging applications such as WeChat, QQ, and SMS. The second mobile terminal has a key management application installed. The user copies the key-sharing information from the instant messaging application, pastes it into the key management application, and then sends the key-sharing information to the terminal server. It should be noted that the key management application is a built-in key management program on the first mobile terminal. Based on this application, it can integrate the management of various keys, including car keys, house keys, and device locks. Therefore, users do not need to separately download and register the corresponding management application from the vehicle's OEM to share digital car keys, achieving the effect of reusing the functions of digital car keys and terminal manufacturers' keys, making it more convenient.

[0053] In practice, after a user copies the key sharing information to the phone's clipboard, the key management application automatically wakes up and sends the key sharing information to the terminal server, thus simplifying the sharing operation of digital car keys.

[0054] Step 140: The terminal server requests a digital car key from the vehicle server based on the key sharing information and sends the digital car key to the second mobile terminal.

[0055] After receiving the key sharing request, the terminal server requests a digital car key from the vehicle server and sends the digital car key to the second mobile terminal, for example, by writing the digital car key into the security chip of the second mobile terminal.

[0056] When different vehicle infotainment systems correspond to different vehicle infotainment servers, the terminal server confirms the vehicle infotainment server corresponding to the key sharing information based on the vehicle infotainment system information, and then sends a key request to the confirmed vehicle infotainment server, so that the vehicle infotainment server returns a digital car key. Thus, by connecting the services of the terminal server with different vehicle infotainment servers, users no longer need to worry about the vehicle infotainment system information of the vehicle they want to share with, simplifying the sharing process and improving the user experience.

[0057] Optionally, after receiving the key application from the terminal server, the vehicle system server sends an SMS verification code to the mobile phone number of the party to be shared in the key application. After receiving the SMS, the party to be shared enters the verification code in the authentication interface of the key management application on the second mobile terminal. The key management application returns the verification code to the vehicle system server for verification. If the verification is successful, a digital car key is generated; if the verification fails, the application is rejected.

[0058] After successful verification, the vehicle's server sends the digital car key to the terminal server, which then writes the digital car key into the phone's security chip. The recipient can then use the digital car key in the key management application, and the digital car key sharing is complete.

[0059] In practice, the key sharing information also includes a sharing validity period. When the vehicle's server receives a key request, it first checks whether the request was received within the sharing validity period. If it is, it proceeds to verify the identity of the recipient based on their information. Therefore, by setting a sharing validity period, the security of the sharing process can be improved.

[0060] Through the above process, the vehicle-mounted server and the terminal server are connected. The terminal server is used to identify the key sharing information and confirm the corresponding vehicle-mounted server, which simplifies the digital car key sharing process and improves the convenience and security of digital car key sharing.

[0061] Figure 2 This is a schematic diagram illustrating the specific process of sharing the digital car key according to this application. For example... Figure 2As shown, the method for sharing the digital car key in this application may specifically include the following steps:

[0062] Step 201: The first mobile terminal sends a digital car key sharing request to the vehicle server. The request parameters are: the sharing party's token and the mobile phone number of the recipient.

[0063] Specifically, the request parameters include information about the sharer and the recipient, which facilitates the vehicle's server in verifying and confirming identities, thereby improving the security of sharing digital car keys.

[0064] Step 202: The vehicle-mounted server receives the request and verifies the identity of the sharing party based on the sharing party information;

[0065] Specifically, the step of verifying the identity of the sharing party can be to verify whether the phone number in the verification request matches the phone number when the first mobile terminal sent the sharing request. If they match, the verification is successful.

[0066] Step 203: Has the information of the sharing party been verified?

[0067] Specifically, if the information of the sharing party fails to pass verification, proceed to step 204; if it passes verification, proceed to step 205.

[0068] Step 204: Reject the application;

[0069] Step 205: The vehicle system server generates key sharing information based on the key sharing request;

[0070] The key sharing information includes information about the sharer, the recipient, and the vehicle's infotainment system.

[0071] Specifically, the information shared by the sharer and the recipient is presented as an encrypted string. The sharer's information includes mobile phone number, vehicle owner's account, etc., and the recipient's information includes mobile phone number, etc. The vehicle system information is presented in plaintext, which protects the privacy of the sharer and recipient during the sharing process of digital car keys and improves the security of the sharing process.

[0072] Specifically, when generating key sharing information, the vehicle's infotainment system server copies and saves it to the cloud.

[0073] Optionally, in the short term, when the first mobile terminal sends a key sharing request to the vehicle's infotainment system server again, after confirming that it is the exact same digital car key based on the sharing request, the identity of the sharing party is confirmed based on the previously verified information. If the verification is successful, the key sharing information in the cloud on the vehicle's infotainment system server is directly retrieved. For example, if the car owner makes another sharing request for the same digital car key in the short term, the vehicle's infotainment system server confirms the identity of the sharing party based on the previously verified identity information. After the verification is successful, the key sharing information is directly retrieved from the cloud. This simplifies the steps of generating a digital car key, speeds up the response time, and improves the efficiency of sharing digital car keys multiple times in a short period of time.

[0074] If the verification fails, the vehicle's server will generate key sharing information based on the key sharing request and continue the sharing process.

[0075] Step 206: The vehicle system server sends the key sharing information to the first mobile terminal;

[0076] Step 207: The first mobile terminal sends the key sharing information to the second mobile terminal;

[0077] Specifically, since both the first and second mobile terminals are equipped with instant messaging applications, the first mobile terminal can share key sharing information through online instant messaging, simplifying the sharing process and improving the reliability of sharing digital car keys.

[0078] Step 208: After receiving the sharing information, the second mobile terminal opens the key management application and sends the sharing information to the terminal server;

[0079] Optionally, by configuring the mobile terminal, the key management application can be automatically activated each time a digital car key sharing message is received, without requiring the user to actively open the application beforehand, thus simplifying the process of sharing digital car keys.

[0080] Step 209: The terminal server confirms the vehicle server corresponding to the shared information based on the vehicle information;

[0081] The vehicle information includes, but is not limited to, vehicle identification numbers.

[0082] Step 210: The terminal server sends a key request to the confirmed vehicle-mounted server;

[0083] Specifically, the terminal server sends a key request to the vehicle's infotainment system server, which then returns a digital car key.

[0084] The key application includes key sharing information.

[0085] Step 211: The vehicle-mounted server determines whether the application received is within the validity period;

[0086] Specifically, if the application is within the validity period, proceed to step 212; if the application has expired, return to step 204.

[0087] Optionally, the validity period can be set by the first terminal when it submits a digital car key sharing request.

[0088] Step 212: The vehicle-mounted server sends verification information to the second mobile terminal based on the contact number;

[0089] Step 213: The second mobile terminal receives the verification information and sends a feedback message;

[0090] Specifically, if the feedback information is correct and the verification is successful, proceed to step 215; if the feedback information is incorrect, proceed to step 214.

[0091] Step 214: The system indicates that the verification failed and asks the second mobile terminal to confirm whether to verify again.

[0092] Specifically, if the verification is confirmed again, return to step 211; if the verification is not confirmed, proceed to step 204.

[0093] Step 215: The vehicle system server generates a digital key for a non-owner and sends it to the terminal server;

[0094] Among them, the non-owner digital car key is different from the owner digital car key, improving the accuracy and convenience of sharing digital car keys with the vehicle's server.

[0095] Step 216: The terminal server writes the digital car key into the security chip of the second mobile terminal;

[0096] Specifically, after receiving the digital car key, the terminal server automatically writes it into the security chip of the second mobile terminal and saves it to the terminal server.

[0097] Specifically, when the second mobile terminal key management application receives the same digital car key sharing information again in a short period of time, it confirms that the digital car key is exactly the same based on the sharing information, generates a key retrieval command and sends it to the terminal server. The terminal server reconfirms the identity of the second terminal based on the previously verified information. If the verification is successful, it directly retrieves the digital car key stored in the terminal's cloud and writes it into the second mobile terminal's security chip. This simplifies and skips the steps of the terminal server identifying the vehicle server, the terminal server sending a key application, and verifying the identity of the second mobile terminal, thus improving the efficiency when sharing digital car keys multiple times in a short period of time.

[0098] If the verification fails, the terminal server will confirm the corresponding vehicle-mounted server based on the vehicle-mounted information in the key sharing information, and send the key application to the confirmed vehicle-mounted server.

[0099] Step 217: Key sharing complete.

[0100] Through the above process, the vehicle-mounted server and the terminal server are connected. After identity verification, the vehicle-mounted server sends the digital car key to the terminal server, which directly writes the digital car key into the terminal's security chip. This simplifies the digital car key sharing process and improves the convenience and security of digital car key sharing.

[0102] The first mobile terminal 301 is used to send a key sharing request to the vehicle server;

[0103] The vehicle-mounted server 302 is used to generate key sharing information based on the key sharing request and send it to the first mobile terminal so that the first mobile terminal can send the key sharing information to the second mobile terminal.

[0104] The second mobile terminal 303 is used to send key sharing information to the terminal server;

[0105] Terminal server 304 is used to request a digital car key from the vehicle system server based on the key sharing information and send it to the second mobile terminal.

[0106] Optionally, based on the key sharing information including the sharing party information, the sharing recipient information, and the vehicle system information, the terminal server is used to request a digital car key from the vehicle system server based on the key sharing information, including:

[0107] Confirm the vehicle server corresponding to the key sharing information based on the vehicle information;
