Based on the communication connection between the mobile terminal and the server, the mobile terminal can forward the vehicle information to the server.
It is understood that the vehicle information may include at least one of a vehicle type, a vehicle money, and an age. In some embodiments, the Vehicle information includes a Vehicle Identification Number (VIN). The VIN code consists of 17-digit characters, commonly called seventeen-digit codes, and correct interpretation of the VIN code is very important for accurately identifying the vehicle type so as to perform correct diagnosis and maintenance. The vehicle identification code is determined according to the national vehicle management standard and includes information of a manufacturer, a year, a vehicle type, a vehicle body type and code, an engine code, an assembly site, and the like of the vehicle. Therefore, after the VIN code is acquired, the information related to the automobile can be analyzed.
It is understood that the VIN code is equivalent to the identity of the car and is the unique identity of the car. Thus, the server can determine the matching procedure and the key generation algorithm from the vehicle information (VIN code).
The matching process is equivalent to a user operation guide in the matching process. The matching process may include, but is not limited to, the following processes:
1. connecting the automobile communication interface equipment with an automobile; 2. turning on an ignition switch of the automobile; 3. transmitting vehicle information of the automobile; 4. clicking a 'matching' virtual button to trigger the automobile to enter a matching state; 5. the server calculates and generates key data; 6. a user brings the automobile remote control key close to the induction area of the automobile; 7. the user presses the unlock key on the automobile remote control key, and the like, so as to complete matching.

It can be understood that the matching process is different for different automobiles, and the matching process and the vehicle information have a one-to-one correspondence relationship. Matching processes corresponding to various types of automobiles (vehicle information) can be collected on the server. Therefore, after the vehicle information is known, the matching process can be determined, and the mobile terminal is adopted for displaying, so that the guiding and imaging operation steps are provided, and the use by a user is facilitated.
The key generation algorithm is an algorithm for generating key data of the car. The key data includes a password, which may be a string of characters. The password is equivalent to a pass of an automobile anti-theft system and corresponds to automobiles one by one. Only if the control signal sent by the automobile remote control key carries the password, the automobile anti-theft system can work according to the indication of the control signal, such as unlocking and the like. It can be understood that if the password carried by the control signal transmitted by the car key fob does not correspond to the car, the car will not respond to the control signal of the car key fob.
It will be appreciated that the key generation algorithm is different for different cars, i.e. the cars have a one-to-one correspondence with the key generation algorithm. The server may collect key generation algorithms corresponding to various types of automobiles (vehicle information). Thus, the key generation algorithm can be determined upon knowledge of the vehicle information.
In some embodiments, the key generation Algorithm may use the existing 256-bit Advanced Encryption Standard (AES 256) or International Data Encryption Algorithm (International Data Encryption Algorithm), etc. Specifically, the determination may be specifically determined according to the actual vehicle type, and is not limited herein.
In some embodiments, the server stores a database including vehicle information, matching modules, and key generation algorithms having a correspondence. Therefore, after the server receives the vehicle information of the automobile, the target matching module and the target key generation algorithm corresponding to the vehicle information of the automobile can be found out from the database. It is to be understood that, here, the target matching module is a kind of matching module, and the target key generation algorithm is a kind of key generation algorithm.
The matching module is a packaged program code file, and after the matching module runs, the matching process is generated. The matching module thus comprises program code files related to the front end presentation and program code files related to the back end data call, based on the front end presentation and the back end data call being involved in the matching process. Therefore, the server sends the target matching module to the mobile terminal, and the mobile terminal can generate a matching flow after loading and operating the target matching module.
In this embodiment, the target matching module is run on the mobile terminal, so that the matching process is displayed according to the running steps, which facilitates human-computer interaction, for example, as shown in fig. 2, after the user clicks the "matching" virtual button, the interface "prompting the user to approach the automobile remote control key to the sensing area of the automobile" is skipped. Compared with the mode that the matching processes are all displayed in one interface, the matching processes are displayed according to the operation steps, namely, the matching processes are displayed in an interactive mode, so that the method is clearer and is convenient for users to operate.
And triggering the automobile to enter a matching state along with the operation of the user according to the indication of the matching process on the mobile terminal, and sending the anti-theft related data to the automobile communication interface equipment by the automobile after the automobile enters the matching state. The anti-theft related data is data used for calculating key data and related to the automobile. In some embodiments, the antitheft related data may be data related to ECUs in the antitheft system, such as a Serial Number (SN), SN code.
It will be appreciated that the automotive communication interface device transmits the theft prevention related data to the server via the mobile terminal.
It is understood that the anti-theft related data follows a certain communication protocol, and can be obtained by analyzing and calculating by the automobile communication interface device or the mobile terminal.
In some embodiments, after the communication is established among the mobile terminal, the car communication interface device and the car, the car communication interface device also sends its own version information to the mobile terminal, so that the mobile terminal can control the car communication interface device to update the security firmware according to its version information.
Based on the matching module comprising the program code file related to the front-end display and the program code file related to the back-end data call, the mobile terminal can generate a matching flow after loading and running the target matching module, and the confidential firmware is a program corresponding to a flow needing confidential running in the matching flow. The version information of the automotive communication interface device reflects information of its confidential firmware.
For example, when the security firmware is a program for analyzing the theft-prevention related data, for example, after the security firmware is operated, the information file of the theft-prevention related data transmitted from the vehicle is processed, analyzed, and calculated to read the SN code.
It is understood that different automobiles read the SN code in different ways (different programs), i.e., different security firmware is required, and the security firmware has a one-to-one correspondence with the vehicle information. After the mobile terminal acquires the vehicle information, the corresponding target security firmware can be determined according to the vehicle information, and then the corresponding target security firmware is sent to the automobile communication interface equipment, so that the security firmware in the automobile communication interface equipment can be updated. In some embodiments, the security firmware may also be a part of the matching module, and after the mobile terminal obtains the security firmware, the security firmware is sent to the vehicle communication interface device, so as to update the security firmware in the vehicle communication interface device.
The security firmware runs in the automobile communication interface equipment, reads information sent by an automobile, analyzes an SN (serial number) code, sends the SN code to the mobile terminal and forwards the SN code to the server.
In the embodiment, the program corresponding to the flow needing the confidential operation runs in the automobile communication interface equipment, and the automobile communication interface equipment is in indirect communication connection with the server, namely the Internet is not connected, so that the confidential firmware is not easy to crack, and the confidentiality and the safety of matching can be improved.
And after the server receives the anti-theft related data, generating key data according to the anti-theft related data and a key generation algorithm. Generating key data based on a key generation algorithm in combination with anti-theft related data is known to the person skilled in the art and the specific principles thereof will not be described in detail here.
And finally, the server sends the key data to the automobile through the mobile terminal and the automobile communication interface equipment. And the user leads the blank automobile remote control key to be close to the induction area of the automobile according to the operation guide on the mobile terminal, so that the automobile writes the key data into the automobile remote control key to complete matching.
In some embodiments, after the server calculates the key data, the key data is sent to the mobile terminal, and then the mobile terminal may prompt the user to bring the blank car key fob close to the sensing area of the car through the app interactive interface, store the identifier (i.e., the identification number) of the car key fob, and complete the identity authentication. Then, the mobile terminal sends the key data to the automobile communication interface device, and the key data is sent to the automobile by the automobile communication interface device.
The method includes the steps that operation is carried out along with pressing of a user according to an indication of a matching process on the mobile terminal, for example, the user clicks a 'write command' virtual key in an app interactive interface of the mobile terminal, then an operation instruction (namely, a write command) for writing a password is transmitted to an automobile through automobile communication interface equipment, and after the automobile receives the write command, key data are written into a blank automobile remote control key.
In the embodiment, firstly, the automobile and the blank automobile remote control key are subjected to identity authentication, the automobile stores the identifier of the automobile remote control key, and then the automobile is controlled by the mobile terminal to write the key into the automobile remote control key, so that errors are not easy to occur in the matching process.
