Description

Technical Field

[0001] The present invention relates to the technical field of vehicle identification, and in particular to a system and method for identifying a modified vehicle. Background Art

[0002] With the rapid development of China's automobile industry, many automakers have been constantly updating their models to attract consumers. Before new models are put into production and put on the market, they need to undergo a lot of experiments, including durability experiments, sealing experiments, NVH experiments, collision experiments, etc. Therefore, automakers will produce a large number of experimental vehicles. These vehicles are disposed of by selling them at a low price or scrapping them. Therefore, many unscrupulous merchants and individuals have also gained business opportunities from this, such as assembling and assembling scrapped vehicles, forging vehicle information and then selling them, and forming an industrial chain.

[0003] At present, there are a large number of assembled / modified vehicles on the road. These illegally driven vehicles not only have great hidden dangers, but more seriously, they have a high accident rate and great harm, which poses great risks to other road traffic participants. However, as many illegal businesses and individuals have become more and more sophisticated in their assembly / modification and counterfeiting methods, it is becoming increasingly difficult for vehicle management departments to identify such illegal vehicles.

[0004] Faced with the above problems, the vehicle management department mainly relies on the experience of inspectors to judge whether the registered / transferred vehicle is the same vehicle as the vehicle corresponding to the vehicle certificate. Inspectors check and read the vehicle identification code (VIN), engine model and engine number to see if it is consistent with the vehicle information shown on the vehicle certificate, or whether there are obvious signs of tampering.

[0005] However, the current counterfeiting methods not only tamper with the vehicle identification number (VIN) of the vehicle system, but also forge and change the vehicle identification number (VIN) engraved on the vehicle. Based on the experience of the inspectors, it will still cause a large number of scrapped vehicles to flow into the market. At present, there is an urgent need for a system and method to collect the registration / transfer vehicle information through equipment and identify abnormal vehicles through platform comparison.

[0020] Figure 1 The structure of a modified vehicle identification system provided by an embodiment of the present invention is as follows: Figure 1 As shown, the system comprises: Vehicle information collection system 101, cloud platform system 102, vehicle management terminal system 103. The vehicle information collection system 101 is used to obtain the data of the vehicle CAN (Controller Area Network) bus through the vehicle OBD (On-Board Diagnostics) interface, so as to connect the electronic module of the vehicle, and then send a specific serial number acquisition request to each electronic module of the vehicle, receive the response data fed back by the vehicle electronic module, analyze the received response data, and extract the serial number of each electronic module. The electronic module may include: engine control module, automatic transmission control module, headlight control module, central door lock control module, ABS control module, electric window control module, instrument panel control module, airbag control module, automatic air conditioning control module, and electronic suspension control module. For the serial number of the electronic module, a corresponding string is generated, wherein the rule for generating the string can be adjusted accordingly according to the type and quantity of the electronic module. For example, when the target vehicle has all the above-mentioned electronic modules, all serial numbers of the above-mentioned electronic modules can be concatenated, and separators and check bits can be added, and then hash operations can be performed through hash functions to generate a fixed hash value, which is the character string of the target vehicle. When the target vehicle does not have all the above-mentioned electronic modules, such as no electronic suspension control module, or the serial number of the electronic suspension control module has not been received, the character string generation rules can be adjusted accordingly, such as adjusting separators and check bits to generate a character string without an electronic suspension control module.

[0021] After the string is generated, it is converted into a vehicle QR code. When the QR code generation system generates the vehicle QR code, it can obtain the vehicle model of the target vehicle and select the corresponding QR code generation rules based on the vehicle model. For example, according to different vehicle models, the corresponding adjustment rules include the encoding method, data format, check digit, etc. of the QR code, and then generate the corresponding vehicle QR code through the Python library. The generated vehicle QR code is sent to the cloud platform system.

[0022] The cloud platform system 102 includes a vehicle information tracing database uniformly built and supervised by the vehicle management department, which is used to receive the vehicle QR code image transmitted by the vehicle information collection system, and temporarily store the received QR code image, and then decode the vehicle QR code through the QR code parsing library (such as qrcode), read the data in the QR code, extract the string including the electronic module serial number from the QR code, and then parse the extracted string in a predefined format, separate the serial number of each electronic module, and verify the check bit (such as CRC) in the string to ensure the integrity of the data. The parsed electronic module serial number is compared with the legal electronic module VIN code pre-stored in the database, and the comparison result includes that the vehicle is normal or the vehicle is an illegally modified vehicle, wherein the illegal modification further includes illegal modification of all and illegal modification of part of the electronic module. The comparison result is sent to the vehicle management terminal system.

[0023] The vehicle management terminal system 103 is used to receive the comparison result between the electronic module serial number of the target vehicle and the legal electronic module VIN code pre-stored in the vehicle management database, wherein the comparison result can be displayed on the display module of the vehicle management terminal system, and specifically may include that if the display module shows that the vehicle identification result is normal, the vehicle can be registered / transferred normally; if the display module shows a vehicle alarm signal, it means that the registered / transferred vehicle is inconsistent with the vehicle corresponding to the vehicle certificate information, and the vehicle is suspected of assembly or modification, which needs to be further investigated by the relevant authorities.

[0024] In addition, in this embodiment, the assembled and modified vehicle identification system can also include a communication key system when the vehicle information collection system interacts with the cloud platform system, specifically including the encryption system of the vehicle information collection system and the decryption system of the cloud platform system. In the encryption system, the inspection time and encryption rules of the target vehicle are obtained, and then a feature string is generated based on the vehicle model and the inspection time, and a hash operation is performed on the feature string to obtain a key string of fixed length, and then based on the encryption rules, the QR code is encrypted by the key string. The encryption method can be, for example, AES encryption of the QR code image by the key string to obtain the encrypted QR code image. The QR code of the vehicle electronic module is encrypted by the vehicle model and the inspection time, which ensures the uniqueness of the key and further improves the security of information transmission. After the encryption is completed, the encryption system sends the encrypted vehicle QR code, vehicle model, and inspection time to the decryption system of the cloud platform system. The decryption rules in the decryption system are determined based on the encryption rules. The same key string is generated by the vehicle model and the inspection time, and the QR code image is reversely decrypted to obtain the decrypted QR code image. The encryption and decryption system can prevent the QR code from being intercepted during the communication process, thereby preventing criminals from obtaining the serial number of the electronic module and counterfeiting it accordingly.

[0025] In addition, in this embodiment, the modified vehicle identification system may also include retained information in the cloud platform system, wherein the retained information is used to retain the vehicle detection results. When the information is retained, it is detected whether there is identity information of the target vehicle user uploaded. When the identity information of the target vehicle user exists, the identity information is saved in correspondence with the identification result of the target vehicle. After the identity of the vehicle owner is saved in correspondence, in the subsequent vehicle detection process, it can be further detected whether the current driver of the vehicle is the original owner, thereby identifying whether the vehicle has an illegal owner change.

[0026] In addition, in this embodiment, the assembled and modified vehicle identification system may also include an alarm system of the vehicle management terminal system, wherein the alarm system is used to send an alarm message to the binding terminal when the serial number of the target vehicle does not match the comparison result of the legal electronic module VIN code in the comparison result. In addition, when sending information to the binding terminal, it is also possible to further determine which electronic modules in the comparison result do not match, and to issue targeted alarms to the mismatched electronic modules, so as to have a more specific understanding of the abnormalities in the vehicle.

[0027] The modified vehicle identification system provided in this embodiment includes: a vehicle information collection system, a cloud platform system, and a vehicle management terminal system; the vehicle information collection system is used to connect the electronic module of the target vehicle, and obtain the serial number of the electronic module, generate a character string based on the serial number, and convert the character string into a vehicle QR code, and upload the vehicle QR code to the cloud platform system; the cloud platform system is used to receive the vehicle QR code, decode the vehicle QR code, obtain the serial number of the target vehicle, and compare it with the legal electronic module VIN code pre-stored in the vehicle management database, and send the comparison result to the vehicle management terminal system; the vehicle management terminal system is used to send a vehicle normal signal or a vehicle alarm signal according to the comparison result after receiving the comparison result. In this way, it is possible to identify whether the vehicle is consistent with the vehicle corresponding to the vehicle certificate information through the vehicle's electronic module identification, avoid the misjudgment caused by the experience of the vehicle management department inspector, and improve the accuracy of the detection.

[0028] Figure 2 A flowchart of a modified vehicle identification method provided by an embodiment of the present invention includes: Step 201, the vehicle information collection system connects to the electronic module of the target vehicle and obtains the serial number of the electronic module, generates a character string based on the serial number, converts the character string into a vehicle QR code, and uploads the vehicle QR code to the cloud platform system.

[0029] Specifically, the vehicle information collection system obtains the data of the vehicle CAN (Controller Area Network) bus through the vehicle OBD (On-Board Diagnostics) interface, thereby connecting the electronic module of the vehicle, and then sends a specific serial number acquisition request to each electronic module of the vehicle, receives the response data fed back by the vehicle electronic module, analyzes the received response data, and extracts the serial number of each electronic module. Among them, the electronic module may include: engine control module, automatic transmission control module, headlight control module, central door lock control module, ABS control module, electric window control module, instrument panel control module, airbag control module, automatic air conditioning control module, electronic suspension control module. For the serial number of the electronic module, a corresponding string is generated, wherein the string generation rule can be adjusted accordingly according to the type and quantity of the electronic module. For example, when the target vehicle has all the above electronic modules, all the serial numbers of the above electronic modules can be spliced, and separators and check bits can be added, and then hash operations are performed through hash functions to generate a fixed hash value, which is the string of the target vehicle. When the target vehicle does not have all the above electronic modules, such as no electronic suspension control module, or the serial number of the electronic suspension control module is not received, the string generation rules can be adjusted accordingly, such as adjusting the separator and the check digit to generate a string without the electronic suspension control module. After the string is generated, the string is converted into a vehicle QR code. When the QR code generation system generates the vehicle QR code, the vehicle model of the target vehicle can be obtained, and the corresponding QR code generation rules can be selected based on the vehicle model. For example, according to different vehicle models, the corresponding adjusted rules include the encoding method, data format, check digit, etc. of the QR code, and then the corresponding vehicle QR code is generated through the Python library. And the generated vehicle QR code is sent to the cloud platform system.

[0030] Step 202, the cloud platform system receives the vehicle QR code, decodes the vehicle QR code, obtains the serial number of the target vehicle, and compares it with the legal electronic module VIN code pre-stored in the vehicle management database, and sends the comparison result to the vehicle management terminal system.

[0031] Specifically, the cloud platform system receives the vehicle QR code image transmitted by the vehicle information collection system, temporarily stores the received QR code image, and then decodes the vehicle QR code through the QR code parsing library (such as qrcode), reads the data in the QR code, extracts the string including the electronic module serial number from the QR code, and then parses the extracted string in a predefined format, separates the serial number of each electronic module, and verifies the check bit (such as CRC) in the string to ensure the integrity of the data. The parsed electronic module serial number is compared with the legal electronic module VIN code pre-stored in the database. The comparison result includes that the vehicle is normal or the vehicle is an illegally modified vehicle, among which the illegal modification further includes illegal modification of all and illegal modification of part of the electronic module. The comparison result is sent to the vehicle management terminal system.

[0032] Step 203, after receiving the comparison result, the vehicle management terminal system sends a vehicle normal signal or a vehicle alarm signal according to the comparison result.

[0033] Specifically, the vehicle management terminal system receives the comparison result of the electronic module serial number of the target vehicle and the legal electronic module VIN code pre-stored in the vehicle management database, wherein the comparison result can be displayed on the display module of the vehicle management terminal system, and specifically may include that if the display module shows that the vehicle identification result is normal, the vehicle can be registered / transferred normally; if the display module shows a vehicle alarm signal, it means that the registered / transferred vehicle is inconsistent with the vehicle corresponding to the vehicle certificate information, and the vehicle is suspected of assembly or modification, which needs to be further investigated by the relevant authorities.

[0034] It should be understood that, although the steps in the flowchart of the accompanying drawings are displayed in sequence as indicated by the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least a part of the steps in the flowchart of the accompanying drawings may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.

[0035] The above is only a partial implementation of the present invention.
