Obviously, the drawings described below are only embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] With the vigorous development of the automobile industry, the technology and services in the field of automobile diagnosis are also constantly improving. When a vehicle breaks down, some faults can be repaired only by calibrating the function of the diagnostic equipment, while others can only be repaired by replacing parts at a car repair shop. However, the repair methods of car repair shops are not transparent. After maintenance or repair, car owners cannot effectively know the actual situation of the replacement of vehicle parts, resulting in the risk of fraudulent replacement of parts and theft of original car parts. In order to solve this problem, car owners generally take photos or record the status of vehicle parts before sending the vehicle for repair, but this requires car owners to understand the repair process and the parts and repair steps that need to be replaced; in addition, car owners can also seek professional opinions from third parties, but there is a problem of high costs, and the above methods cannot ensure that the replacement of vehicle parts can be fully identified.

[0044] Based on this, in each embodiment of the present application, the first component verification information of the target vehicle component before maintenance and the second component verification information after maintenance obtained by using a diagnostic device are compared, and the legitimacy of the target vehicle component is verified based on the verification result obtained after the comparison.

[0045] The various embodiments of the present application are described in further detail below in conjunction with the accompanying drawings.

[0046] The present application embodiment provides a vehicle component verification method, such as Figure 1 As shown, the method includes steps S101-S103.

[0047] S101: obtaining first component verification information of each target vehicle component before repair, and obtaining second component verification information of each target vehicle component after repair;

[0048] Diagnostic equipment refers to a special tool used to detect and diagnose vehicle faults. Diagnostic equipment can communicate with the electronic control unit (ECU) of each control system of the vehicle through the vehicle's on-board diagnostic system (OBD) interface. By selecting the corresponding diagnostic function, such as reading fault codes, clearing fault codes, reading vehicle data streams, etc., various parameters and status information of the vehicle can be obtained.

[0049] The target vehicle components may include various control systems and components in the target vehicle, such as spark plugs in the engine system, transmissions and drive shafts in the transmission system, brake pads in the brake system, etc. The component verification information of each of the above control systems or components can be read by using diagnostic equipment. The component verification information generally includes but is not limited to the following: component identification code (such as injector code, tire pressure sensor code, etc.), ECU software identification code, ECU hardware identification code and fault identification code.

[0050] In the embodiment of the present application, the first component verification information (i.e., the original vehicle component code) of each component of the target vehicle can be recorded by using the diagnostic device before maintenance, so as to be used for comparison with the vehicle components after subsequent maintenance. After maintenance, the diagnostic device is used to scan and record the second component verification information of each component of the target vehicle again to obtain possible changes in each vehicle component during the maintenance process.

[0051] S102: Compare the first component verification information of each target vehicle component with the second component verification information to obtain a verification result of each target vehicle component;

[0052] Compare the first component verification information recorded before maintenance and the second component verification information recorded after maintenance of the same target vehicle component to check whether there are any inconsistencies. For example, taking the brake pad of the brake system as an example, the component identification code of the brake pad is used as the component verification information. The diagnostic device reads the first component verification information of the brake pad before maintenance as AKE1234, and the second component verification information after maintenance as AKE5678. After comparing the first component verification information AKE1234 and the second component verification information AKE5678, it can be obtained that the verification result of the brake pad is inconsistent.

[0053] S103: Verify the legitimacy of each target vehicle component according to the verification result of each target vehicle component.

[0054] If the verification result indicates that the first component verification information of the target vehicle component is consistent with the second component verification information, then there is no replacement of the vehicle component, and the target vehicle component is determined to be legal;

[0055] If the verification result indicates that the first component verification information and the second component verification information of the target vehicle component are inconsistent, the first component verification information and the second component verification information can be further analyzed, and the target vehicle component may be replaced normally, repaired incorrectly, or replaced maliciously. If the target vehicle component is confirmed to be replaced normally after analysis, the target vehicle component is confirmed to be legal; if it is determined that the target vehicle component is replaced incorrectly or maliciously, the target vehicle component is confirmed to be illegal.

[0056] The embodiment of the present application obtains the first component verification information of the target vehicle component before maintenance and the second component verification information after maintenance, and compares the component verification information before and after maintenance, which can effectively identify whether the component has changed, ensure that all vehicle component replacements are verified and legal, and thus protect the overall legality and safety of the vehicle. At the same time, the first component verification information and the second component verification information and the verification result obtained after comparing the two can also be used to confirm whether there is illegal replacement of components or use of non-genuine components during the maintenance process, ensuring the transparency of vehicle maintenance, helping car owners understand the actual maintenance status of the vehicle, and preventing fraud during the maintenance process.

[0057] In addition, in an embodiment of the present application, the vehicle identification codes (VIN, Vehicle Identification Number) of each control system / body of the target vehicle before and after maintenance can be obtained and compared respectively. If they are consistent, the vehicle component verification method provided in the present application can continue to be executed; if they are inconsistent, the VIN codes of each control system / body of the target vehicle before and after maintenance can be recorded first, and the vehicle component verification method provided in the present application can continue to be executed, and then the first component verification information and the second component verification information obtained by executing the vehicle component verification method and the verification result obtained after comparing the two are combined to confirm the legitimacy of the target vehicle components. For example, (1) if it is found that the VIN codes of the vehicle before and after repair are inconsistent, but the subsequent vehicle component verification shows that all vehicle components are legal, it indicates that there is a question about the identity of the vehicle, but the safety and legality of the vehicle are not affected; (2) if it is found that the VIN codes of the vehicle before and after repair are inconsistent, and the vehicle component verification shows that the first and second component verification information of the vehicle components are inconsistent, this also indicates that there is a question about the identity of the vehicle, and the safety and legality of the vehicle may be affected. In the above cases, the diagnostic device can suggest that the owner seek professional identification or provide the same or similar cases located in the diagnostic device cloud platform system for reference and decision-making. (3) If it is found that the VIN codes of the vehicle before and after repair are consistent, but the subsequent vehicle component verification shows that all vehicle components are inconsistent, then further analysis can be performed on the inconsistent first component verification information and second component verification information after comparison. (4) If it is found that the VIN codes of the vehicle before and after repair are consistent, but the vehicle component verification shows that all vehicle components are consistent and legal, it indicates that no abnormality is found in the target vehicle, and the legality of the target vehicle and its vehicle components can be confirmed.

[0058] In one embodiment, the legitimacy of each target vehicle component is verified according to the verification result of each target vehicle component, including: if the verification result of the target vehicle component indicates that the first component verification information and the second component verification information of the target vehicle component are consistent, then the target vehicle component is determined to be legal; if the verification result of the target vehicle component indicates that the first component verification information and the second component verification information of the target vehicle component are inconsistent, then the legitimacy of the target vehicle component is verified according to the inconsistent first component verification information and the second component verification information after comparison.

[0059] In practical applications, the verification results can be represented in a variety of ways, such as using Boolean values ​​(such as "True" or "False"), status codes (such as "0" and "1"), or using strings (such as "verification consistent", "verification inconsistent"), etc., which are not limited in the embodiments of the present application.

[0060] If the verification result indicates that the first component verification information and the second component verification information of the target vehicle component are inconsistent, the first component verification information and the second component verification information can be further analyzed, for example, the target vehicle component may be replaced normally, repaired incorrectly, or replaced maliciously. If the target vehicle component is confirmed to be replaced normally after analysis, the target vehicle component is confirmed to be legal; if it is determined that the target vehicle component is replaced incorrectly or maliciously, the target vehicle component is confirmed to be illegal.

[0061] In one embodiment, the legality of the target vehicle component is verified based on the first component verification information and the second component verification information that are inconsistent after comparison, including: obtaining the first component verification information and the second component verification information that are inconsistent after comparison; for the same target vehicle component, if the first component verification information is empty and the second component verification information is not empty, then determining that the target vehicle component is legal.

[0062] Exemplarily, if the component verification information (i.e., the first component verification information) of the target vehicle component is not read before maintenance, but the component verification information (i.e., the second component verification information) of the target vehicle component is read after maintenance, it indicates normal replacement. It is understandable that in this case, it is usually because the target vehicle component is faulty, so the diagnostic device cannot read the component verification information of the target vehicle component before maintenance, and later after detection and maintenance, the fault of the target vehicle component is repaired, so that the target vehicle component can be detected, and then the second component verification information of the target vehicle component after maintenance can be read.

[0063] Furthermore, the above situation can also be judged in combination with the fault identification code. The fault identification code will also be read when the diagnostic equipment reads the first component verification information and the second component verification information of the target vehicle component. If the component verification information (i.e., the first component verification information) of the target vehicle component is not read before maintenance, but the fault identification code corresponding to the target vehicle component is read, and the component verification information (i.e., the second component verification information) of the target vehicle component is read after maintenance, but the original fault identification code before maintenance no longer exists, it can be confirmed that the target vehicle component is replaced normally and the target vehicle component is legal.

[0064] In one embodiment, before comparing the first component verification information of each target vehicle component with the second component verification information, the method further includes: obtaining the fault identification code of each target vehicle component before maintenance and the fault identification code of each target vehicle component after maintenance based on the preset corresponding relationship between the target vehicle component and the fault identification code;

[0065] The verifying the legitimacy of the target vehicle component according to the first component verification information and the second component verification information that are inconsistent after comparison includes:

[0066] Obtain the first component verification information and the second component verification information that are inconsistent after comparison; if it is determined that the target vehicle component corresponding to the fault identification code before maintenance and the target vehicle component corresponding to the first component verification information and the second component verification information that are inconsistent after comparison are the same target vehicle component, then determine that the target vehicle component is legal; otherwise, determine that the target vehicle component is illegal.

[0067] As mentioned above, the fault identification code is read together with the first component verification information and the second component verification information by the diagnostic device. In addition, the diagnostic device will also confirm the corresponding component serial number and so on according to different target vehicle components. In actual use, a mapping table between target vehicle components and fault identification codes can be established, that is, according to the fault code that appears, the corresponding target vehicle component where the fault occurs can be found. Similarly, a mapping table between the component serial number and the fault identification code of the target vehicle component can also be established, that is, according to the fault code that appears, the corresponding component serial number can be found, and finally the corresponding target vehicle component where the fault occurs can be found.

[0068] In the case where the first component verification information is inconsistent with the second component verification information, further analysis can be performed in combination with the fault identification code. If it is determined that the target vehicle component corresponding to the fault identification code before maintenance and the target vehicle component corresponding to the inconsistent first component verification information and the second component verification information after comparison are the same target vehicle component, then the target vehicle component is determined to be legal; otherwise, the target vehicle component is determined to be illegal. Similarly, analysis can also be performed in combination with the component serial number and the fault identification code. For example, first determine the component serial number corresponding to the fault identification code before maintenance, and then determine the target vehicle component corresponding to the component serial number. If the target vehicle component corresponding to the component serial number and the target vehicle component corresponding to the inconsistent first component verification information and the second component verification information after comparison are the same target vehicle component, then the target vehicle component is determined to be legal; otherwise, the target vehicle component is determined to be illegal.

[0069] For example, taking the brake pad of the brake system as an example, the component identification code of the brake pad is used as the component verification information. The diagnostic device reads that the first component verification information of the brake pad before maintenance is AKE1234, and the fault identification code before maintenance is B302; the second component verification information after maintenance is AKE5678, and the fault identification code after maintenance is empty. After comparing the first component verification information AKE1234 and the second component verification information AKE5678. According to the preset correspondence between the target vehicle component and the fault identification code, it can be obtained that the target vehicle component corresponding to the fault identification code B302 before maintenance is exactly the brake pad. At this time, it can be determined that the target vehicle component corresponding to the fault identification code before maintenance and the target vehicle component corresponding to the inconsistent first component verification information and second component verification information after comparison are the same target vehicle component, and then it can be determined that the brake pad is replaced normally and is a legal target vehicle component.

[0070] Furthermore, in a feasible embodiment, the maintenance diagnostic device also stores a preset set of replaceable component identification codes of the target vehicle components; if the first component verification information is inconsistent with the second component verification information and the second component verification information is not within the preset set of replaceable component identification codes of the target vehicle components, it is determined that the target vehicle component has been maliciously replaced or repaired incorrectly, and the target vehicle component is determined to be illegal.

[0071] In another feasible embodiment, if the first component verification information is inconsistent with the second component verification information and the fault identification code before maintenance is empty, the fault identification code after maintenance is not empty, and the second component verification information is not within the preset set of replaceable component identification codes of the target vehicle component, it can be determined that the target vehicle component has been maliciously replaced or incorrectly replaced, and the target vehicle component is determined to be illegal.

[0072] By comparing the component verification information before and after maintenance and combining it with the fault identification code, it is possible to more accurately determine whether the target vehicle component has been correctly replaced or whether a fault exists. It is also able to accurately detect malicious replacement of vehicle components or use of non-genuine vehicle components, thereby improving the accuracy of vehicle component detection.

[0073] In order to improve the transparency of the maintenance process and clearly display and understand the actual maintenance situation of the vehicle, in one embodiment, after obtaining the verification results of the target vehicle components, it also includes: generating a vehicle component verification report according to the verification results of each target vehicle component; wherein the vehicle component verification report includes: first component verification information of the target vehicle component before maintenance, second component verification information of the target vehicle component after maintenance, the verification result, and a reference maintenance price of the target vehicle component for which the verification result indicates that the first component verification information and the second component verification information are inconsistent.

[0074] The first component verification information and the second component verification information in the vehicle component verification report can show the state change of the target vehicle component before and after maintenance. The verification result is used to indicate whether the first component verification information is consistent with the second component verification information, which can be used to evaluate the maintenance effect and determine whether the maintenance is successful. Furthermore, if the verification result shows that the state of the target vehicle component is inconsistent before and after the maintenance, the reference maintenance price of the target vehicle component will also be provided in the vehicle component verification report. The reference maintenance price may fluctuate due to the model and brand, and is usually expressed as a price range or several specific price points. The embodiment of the present application is not limited here; the reference maintenance price can more intuitively display the maintenance or replacement costs of different components and improve the transparency of the maintenance process.

[0075] Based on the comparison results, a vehicle component verification report is generated, which includes the following contents: component serial number, control system name, component name, first component verification information before maintenance, fault identification code before maintenance, second component verification information after maintenance, fault identification code after maintenance, verification results, and reference maintenance price. For details, please refer to the following table:

[0076]

[0077] Further, in one embodiment, if the verification result of the target vehicle component indicates that the first component verification information of the target vehicle component is consistent with the second component verification information, and the fault identification code before the repair is not empty, and the fault identification code after the repair is empty, then it is determined that the target vehicle component has illegal charges. For example, a 2016 Honda Accord is sent to a repair shop because the ACC fault light is on. After the repair, the auto repair shop quotes 800 yuan, and the repair details list shows that the repair labor fee is 100, the repair fee is 200, and the radar replacement fee is 500. The owner has used diagnostic equipment to read and record the first component verification information and fault identification code of each target vehicle component before the repair, as well as the second component verification information and fault identification code after the repair. The verification result of the vehicle component verification report shows that the first component verification information and the second component verification information of the vehicle's radar are consistent, which shows that the radar has not been replaced. The repair shop only solved the fault by performing radar calibration through the car diagnostic software, and should not charge the radar replacement fee, so it can be inferred that the auto repair shop has illegal charges.

[0078] Another 2022 Honda Accord was sent to the repair shop because it could not ignite. The vehicle component verification report showed that the first component verification information of the body ECU before the repair and the second component verification information after the repair were inconsistent, that is, the body ECU was replaced. The owner has used diagnostic equipment to read and record the first component verification information and fault identification code of each target vehicle component before the repair, as well as the second component verification information and fault identification code after the repair. The verification results of the vehicle component verification report show that the body ECU hardware number is inconsistent before and after the repair. Combined with the fact that the car could not ignite before the repair, and the vehicle component verification report showed that there was a fault identification code of "abnormal anti-start device" before the repair, it shows that the body ECU was indeed replaced, so the verification result shows that the body ECU hardware number is inconsistent before and after the repair. After verifying the reference repair price provided by the vehicle verification report and the quotation of the auto repair shop, the replacement cost is also within the reference repair price range, and the repair cost is reasonable.

[0079] Through the embodiments of the present application, the vehicle parts verification report generated by the embodiments of the present application can be easier to understand and more targeted than more professional diagnostic equipment. It can specifically detect whether vehicle parts have been maliciously replaced or incorrectly repaired, and help individual car owners understand the maintenance status of target vehicle parts at a lower cost.

[0080] In one embodiment, it also includes: reporting the verification results and reference repair prices of the target vehicle parts verified as illegal to the cloud server through the diagnostic equipment, wherein the cloud server is used to generate and record illegal repair events based on the verification results and reference repair prices of the target vehicle parts verified as illegal.

[0081] Records of illegal repair incidents help regulatory platforms and car owners track and identify illegal repair practices. After using diagnostic equipment to learn about the specific fault before repair, they generally go to a repair shop for repair and inspection. The significance of illegal repair incidents is that they can find out which repair shops use non-genuine parts, fail to perform repairs in accordance with regulations, etc., which helps car owners make decisions and improves the transparency of car repairs.

[0082] Furthermore, if in the vehicle component verification report, the replacement and repair costs of a certain target vehicle component are higher than the reference repair price, the diagnostic verification process and repair information of the target vehicle component will be published, and repair shops that maliciously replace or arbitrarily remove parts will be marked and publicly notified on the system platform of the diagnostic equipment.

[0083] Furthermore, the diagnostic equipment can also obtain the target vehicle's location, maintenance time, and status changes of each component in real time during the process and display them on the vehicle inspection report, thereby restoring and supervising the maintenance process.

[0084] For example, following the example of the 2016 Honda Accord in the aforementioned embodiment where the ACC fault light was on and the radar was faulty, based on this example, the generated illegal repair event may be "The ACC fault light of the 2016 Honda Accord was on. Repairs on the target vehicle began at the Blue Sky Repair Factory at No. A, Road A, City A, at 15:20. After radar calibration, the vehicle operated normally. The radar was not replaced but the replacement fee was charged."

[0085] As vehicle technology continues to develop and update, the correspondence between fault identification codes and vehicle components on the cloud server may change (for example, new components are added, software versions are updated, fault detection logic is optimized, etc.). In order to ensure that the diagnostic device can correctly identify the actual fault condition of the vehicle, it is necessary to obtain the latest version of the correspondence between fault codes and vehicle components from the cloud server. In a specific implementation, it also includes: using the diagnostic device to obtain the latest version of the correspondence between the target vehicle component and the fault identification code configured in the cloud server;

[0086] Diagnostic equipment should use the same data standards and logic as cloud servers to avoid diagnostic differences due to version inconsistencies. For example, if the diagnostic equipment uses old version data and the vehicle being diagnosed is a newly produced model, the old version data may incorrectly map the fault identification code to an unrelated component, thereby affecting the verification of vehicle components.

[0087] In a specific embodiment, before using the diagnostic device to obtain the first component verification information of each target vehicle component before maintenance, and before obtaining the second component verification information of each target vehicle component after maintenance, it also includes: judging whether the latest version of the correspondence between the target vehicle component and the fault identification code is the same as the preset correspondence between the target vehicle component and the fault identification code; if not, updating the preset correspondence between the vehicle component and the fault identification code to the latest version of the correspondence between the vehicle component and the fault identification code. By updating to the latest version of the correspondence between the vehicle component and the fault identification code, the risk of misdiagnosis and verification can be reduced, and the efficiency of maintenance and vehicle component verification can be improved.

[0088] In order to implement the vehicle component verification method of the embodiment of the present application, the embodiment of the present application also provides a vehicle component verification device, such as Figure 2 As shown, the device comprises:

[0093] The determination unit is further configured to verify the legitimacy of the target vehicle component based on the first component verification information and the second component verification information that are inconsistent after comparison if the verification result of the target vehicle component indicates that the first component verification information and the second component verification information of the target vehicle component are inconsistent.

[0094] In one embodiment, the acquiring unit is further used to acquire the first component verification information and the second component verification information which are inconsistent after comparison;

[0095] The determination unit is further configured to determine, under the same target vehicle component, if the first component verification information is empty and the second component verification information is not empty, that the target vehicle component is legal.

[0097] The verifying the legitimacy of the target vehicle component according to the first component verification information and the second component verification information that are inconsistent after comparison includes:
