[0002] With the continuous development of vehicle intelligence, especially the development of new energy vehicles, more and more functions and car machine functions are being added. Among them, a new form of car keys, digital keys, has also appeared. Digital keys are virtual keys. Through the car owner's mobile phone, the virtual digital key of the vehicle can be activated online, and the digital key can be shared, frozen, and unfrozen online. Compared with traditional physical car keys, digital keys have more comprehensive functions and more advantages, but digital keys also have certain disadvantages. There may be situations where the digital key cannot operate the vehicle, resulting in customer complaints.

[0003] Since most of the abnormalities are caused by the digital key on the vehicle side, the current way to solve this kind of customer complaint is to require professional technicians to come to the vehicle site, or let the user drive the vehicle to a designated after-sales processing center to obtain the SDK log of the digital key on the vehicle side. The log information also needs to be synchronized with the solution provider of the vehicle digital key module. After the solution is agreed upon, a solution is given, and then the on-site technicians perform relevant operations to solve the problem. This method of solving problems is very inefficient, the user experience is very poor, and it is time-consuming and labor-intensive. Users often need to delay for a whole day to solve the key problem. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a vehicle digital key data cloud acquisition method and system to solve the problem in the prior art that it is time-consuming and labor-intensive to obtain relevant data of the digital key on the vehicle side through offline operations by professionals.

[0028] Figure 2 It is a schematic diagram of a processing flow of a method for obtaining vehicle digital key data cloud according to an exemplary embodiment. DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0030] In the field of digital car keys, the mainstream near-field communication modes currently used in the industry are UWB, NFC and Bluetooth. For car manufacturers, the launch of digital keys can first save the development cost and mold production cost of traditional physical car keys. Secondly, digital keys are more convenient for users to carry and use. Therefore, with the development of intelligence and dataization, more and more car manufacturers are beginning to launch digital key services.

[0031] With the gradual development of digital keys, the number of users using digital keys is increasing. In the actual use process of users, there will be abnormal situations such as the digital key cannot control the vehicle, for example, the key cannot unlock the vehicle. This abnormal situation has a great impact on the user's use. Although digital keys have more functions and user experience than traditional car keys, when digital keys no longer have the basic vehicle unlocking function, users will not use digital keys because they are worried that problems may occur at any time and affect their trip.

[0032] At present, after the vehicle digital key technology was launched, there have been many cases where users were unable to use digital keys to control the vehicle. In addition, as the system version is continuously upgraded, the digital key module in the car is also continuously upgraded. Various abnormal situations may occur at any time, causing the digital key to be unusable. The inability to use the digital key normally will lead to user complaints. In order to solve customer complaints, customer service needs to obtain as much vehicle-side information related to the digital key as possible, such as the SDK application version of the digital key module in the car, the application version of different standard keys, and whether there is a key on the vehicle side, whether it is a blacklisted key, and other information. Only by obtaining the desired information through technical means can we locate the user's problem in a timely manner and find a way to solve the problem.

[0033] When the digital key has an abnormal situation as described above, there are two possibilities, the signal sender and the signal receiver. For mobile phones and wearable devices that are signal senders, once the virtual digital key is successfully activated, the actual use transaction does not interact with the device cloud. And at this stage, mobile phone manufacturers have built-in SE chips to store virtual key data, and the functions are stable. It is unlikely that the virtual key of a very few devices cannot be used. Therefore, most of the above-mentioned abnormal situations of the digital key come from the vehicle side as the signal receiver. The MCU of the digital key module on the vehicle side has not received the digital key signal or has received the signal but has not processed the key signal correctly. Therefore, the technicians need to obtain the vehicle-side information about the digital key on the vehicle side. The current offline technicians perform related operations to obtain vehicle-side information. The user experience is very poor, time-consuming and labor-intensive. Often users need to delay for a day to solve the key problem, and the technicians need to face pressure from customers.

[0034] In order to solve the above technical problems, a vehicle digital key data cloud acquisition method and system are proposed.

[0035] In one embodiment, Figure 1 is a schematic diagram of a method for obtaining vehicle digital key data cloud according to an exemplary embodiment, see Figure 1 , a vehicle digital key data cloud acquisition method is provided, comprising:

[0036] Step S11, obtaining the vehicle information to be processed and the vehicle-side information reading instruction.

[0037] In practice, when users file complaints about abnormalities in digital keys, they can obtain information about the vehicle to be processed through other means. For example, if users report problems through the car manufacturer's mobile phone app, they can directly obtain the vehicle frame number. After receiving the complaint, the technician can determine the problem of the vehicle based on the content of the complaint, and edit and input the command to read the vehicle information.

[0038] Step S12: establishing a communication channel between the cloud and the vehicle to be processed according to the information of the vehicle to be processed, and using the communication channel to send the vehicle-side information reading instruction to the vehicle to be processed.

[0039] In order to realize remote data interaction between the cloud and the vehicle, it is necessary to establish a communication channel between the cloud and the vehicle to be processed. Automobile manufacturers can establish a communication channel with the vehicle to be processed in a variety of ways. After the communication channel is established, the communication channel can be used to send the vehicle-side information reading instruction to the vehicle to be processed. Preferably, after the cloud completes the push of the corresponding instruction, it will record the push serial number and wait for the vehicle to complete the execution before reporting the information.

[0040] Step S13, the vehicle to be processed derives the type of vehicle-side information that needs to be obtained according to the instruction type of the instruction for reading the vehicle-side information, obtains the vehicle-side information according to the type of vehicle-side information that needs to be obtained, and returns the vehicle-side information to the cloud.

[0041] After receiving the instruction to read the vehicle-side information, the vehicle to be processed distributes the instruction according to the instruction type, executes corresponding logical processing according to the different instruction types, obtains the desired vehicle-side information, and feeds the vehicle-side information back to the cloud.

[0042] After receiving the vehicle information, the cloud performs corresponding processing, and finally enables the operator to view the desired vehicle information. This eliminates the need for technicians to retrieve vehicle information offline, saving user time.

[0043] It is understandable that the technical solution shown in this embodiment can obtain the vehicle information to be processed and the instruction to read the vehicle-side information; establish a communication channel between the cloud and the vehicle to be processed based on the vehicle information to be processed, and use the communication channel to send the instruction to read the vehicle-side information to the vehicle to be processed; the vehicle to be processed derives the type of vehicle-side information to be obtained based on the instruction type of the instruction to read the vehicle-side information, obtains the vehicle-side information according to the type of vehicle-side information to be obtained, and returns the vehicle-side information to the cloud. It is understandable that the technical solution shown in this embodiment can remotely obtain the vehicle-side information about the digital key on the vehicle to be processed through the cloud, which is convenient for customer service to quickly locate the problem and solve the user problem.

[0044] Preferably, the implementation of step S11 of the vehicle digital key data cloud acquisition method can be achieved by pre-establishing a digital key management platform, because if you want to obtain the vehicle-side application information of a certain vehicle, you must have an entry to actively trigger the acquisition of vehicle-side information. On the established management platform, technicians can query the information of each vehicle that has been offline by the automobile manufacturer. In the vehicle information, technicians can choose to use instructions to obtain the vehicle-side information related to the vehicle's digital key in real time.

[0045] Preferably, the vehicle-side information reading instruction can refer to Table 1:

[0046] Table 1

[0047]

[0048] It should be noted that in step S12 of the vehicle digital key data cloud acquisition method, a communication channel between the cloud and the vehicle to be processed is established based on the information of the vehicle to be processed, including: calling the vehicle factory server corresponding to the vehicle to be processed to retrieve the production line information to which the vehicle to be processed belongs; based on the production line information, requesting the production line server to which the vehicle to be processed belongs to establish a communication channel between the cloud and the vehicle to be processed.

[0049] In specific practice, the digital key management platform obtains the vehicle-side information related to the vehicle's digital key and needs to establish a communication connection with the vehicle. When the operation customer service receives the customer complaint sent by the user, the management platform can trigger the process of obtaining the vehicle-side information. According to the information of the vehicle to be processed, the vehicle factory server corresponding to the vehicle to be processed can be called to enable the vehicle factory server to retrieve the production line information to which the vehicle belongs. According to the production line information, the corresponding production line server of the vehicle is requested, and then a communication connection is established with the vehicle to be processed, thereby realizing data interaction between the cloud management platform and the vehicle.

[0050] It should be noted that in step S12 of the vehicle digital key data cloud acquisition method, the communication channel is used to send the vehicle-side information reading instruction to the vehicle to be processed, including: encrypting and encoding the vehicle-side information reading instruction to generate an encrypted instruction; pushing the encrypted instruction to the vehicle to be processed; after receiving the encrypted instruction, the vehicle to be processed decrypts the encrypted instruction to obtain the vehicle-side information reading instruction.

[0051] In practice, after the cloud obtains the vehicle-side information reading instruction and completes the instruction encapsulation, the instruction will be encrypted and Base64-encoded to ensure security, and pushed to the vehicle to be processed through MQtt technology. The vehicle to be processed receives the encrypted instruction through the vehicle's signal receiving module, decrypts the encrypted instruction, and obtains the vehicle-side information reading instruction.

[0052] It should be noted that in step S13 of the vehicle digital key data cloud acquisition method, the vehicle-side information is acquired according to the type of vehicle-side information that needs to be acquired, including: distributing instructions according to the type of vehicle-side information that needs to be acquired, executing preset logical processing corresponding to the instruction for reading the vehicle-side information, and acquiring the vehicle-side information.

[0053] The technical implementation scheme of the car key in the prior art includes a digital key MCU module, which has a built-in SE security chip. In this chip, multiple digital key applications can be installed. For example: keys that comply with the international automobile digital key CCC specification. And digital keys for private Bluetooth protocols. In the digital key MCU module, a car-side SDK is included to handle various business logic processing of the key.

[0054] In terms of technical implementation, the technical solution shown in this embodiment transforms the vehicle-side SDK and adds a control distributor that can determine the type of vehicle-side information that needs to be obtained based on the instruction type and distribute instructions.

[0055] When receiving a command, the SDK can first determine whether it is a command type that can be processed. If so, it will distribute the command. If not, it will directly report the vehicle-side abnormal information to the cloud.

[0056] When distributing instructions, if the instruction is to obtain the version number, the MCU reads the version number of the SDK and accesses SE to read the version number of the key application; if the instruction is to read the ICCE key version number, the SE is accessed to read the version number of the ICCE key application; if the instruction is to read the CCC key version number, the SE is accessed to read the version number of the CCC key application; if the instruction is to obtain the CCC key blacklist, the SE is accessed to read the blacklist key of the CCC key application; if the instruction is to obtain the data of the specified length at the address specified by the MCU, the data of the specified length at the address specified by the MCU is obtained; if the instruction is to send an APDU instruction, the SE is accessed to send a user-defined instruction; if the instruction is to read the SEID, the unique ID of the SE security chip is read; if the instruction is to read the mac address of the Bluetooth module of the MCU, the Bluetooth mac address of the MCU is read; if the instruction is to read the key list, the list of installed keys in each standard key application is accessed.

[0057] After the SDK accesses the MCU or SE to obtain the vehicle-side information, it will push the results and eventually report the vehicle-side information to the cloud through existing functions.

[0058] Preferably, the result data format reported by the vehicle end is shown in Table 2:

[0059] Table 2

[0060]

[0061]

[0062] After receiving the reported vehicle information, the cloud performs corresponding processing, and finally enables the operator to view the desired vehicle information. The operator performs corresponding operations according to the vehicle information results. If the corresponding APDU command needs to be sent to the vehicle, a command can be sent through type 07 in Table 1 to be executed on the vehicle, thus solving the problem.

[0063] Since the key information is stored in the corresponding application, the application stores the relevant information of the key. In the technical implementation of this solution, the application Applet is modified and an entry for obtaining the corresponding information is added to facilitate SDK calling.

[0064] See also Figure 2After receiving the customer complaint, the operation triggers the process of querying the vehicle application information on the digital key management platform. After executing the vehicle digital key data cloud acquisition method, the vehicle information is obtained. The technician checks the vehicle information. If the problem is located and there is a solution, the corresponding measures and solutions are taken to solve the customer complaint. If the problem is not located or there is no solution, the customer problem is solved through other means.

[0065] Through the cloud management platform, vehicle-side SDK and SE security chip application transformation, a closed loop of functions can be realized to trigger from the cloud and obtain the vehicle-side key application information of the specified vehicle. When the operation staff receives customer complaints, they can obtain all the information related to the vehicle-side digital key through the above functions in the first time to quickly solve the customer problem.

[0066] According to a second aspect of an embodiment of the present invention, a vehicle digital key data cloud acquisition system is provided, comprising:

[0067] The digital key management platform is used to receive the vehicle information to be processed, establish a communication channel between the cloud and the vehicle to be processed according to the vehicle information to be processed, and obtain a vehicle information reading instruction, and send the vehicle information reading instruction to the vehicle to be processed using the communication channel;

[0068] The vehicle to be processed is used to receive the vehicle-side information instruction, derive the type of vehicle-side information that needs to be obtained according to the instruction type of the vehicle-side information reading instruction, obtain the vehicle-side information according to the type of vehicle-side information that needs to be obtained, and return the vehicle-side information to the cloud.

[0069] In actual practice, users can report problems through the APP on the smart terminal. After receiving the pending vehicle information reported by the problem, the digital key management platform requests the manufacturer's server to establish a communication connection with the vehicle and push the vehicle-side information reading instruction to the vehicle.

[0070] The vehicle information receiving module of the vehicle to be processed receives the instruction to read the vehicle information, sends it to the digital key MCU through the vehicle T-BOX terminal, and uses the vehicle SDK in the digital key MCU to access the vehicle application to obtain the vehicle information.

[0071] It should be noted that the vehicle-side SDK in the digital key MCU of the vehicle to be processed has a control distributor. When the vehicle-side SDK receives the vehicle-side information instruction, it uses the control distributor to derive the type of vehicle-side information that needs to be obtained according to the instruction type of the instruction for reading the vehicle-side information. The vehicle-side SDK obtains the vehicle-side information according to the type of vehicle-side information that needs to be obtained.

[0072] It should be noted that the application of the SE safety chip of the vehicle to be processed is provided with an information acquisition entry, and the vehicle-side SDK uses the information acquisition entry to acquire vehicle-side information.
