[0030] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0031] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0032] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0033] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0034] First of all, it should be noted that the annual inspection of new energy vehicles is more complicated than that of traditional fuel vehicles, because new energy vehicles have added core components such as power batteries, motors, and electronic controls. The safety and performance of these components are crucial to the overall operation of the vehicle. Therefore, the annual inspection of new energy vehicles mainly includes the following aspects: Vehicle appearance: Check whether the body, lights, tires, etc. are intact, without damage, deformation or abnormal wear. Safety devices: Including seat belts, brake systems, steering systems, etc., to ensure that they function normally without failures or safety hazards. Chassis and brakes: Check whether the chassis is rusted or deformed, and whether the brake system is sensitive and reliable. Power battery: Perform safe charging and electrical safety tests on the power battery to ensure that it is in good working condition and has no safety hazards such as leakage and short circuit. For operating new energy vehicles, the temperature and voltage of the power battery during charging and discharging will also be tested. Drive motor and electronic control system: Check the operating status of the drive motor and electronic control system to ensure that its performance is stable and there is no abnormal noise, overheating, etc. With the continuous increase in the number of new energy vehicles, relevant departments are also constantly improving the annual inspection standards and procedures for new energy vehicles. Listing power battery safe charging test and electrical safety test as mandatory inspection items further improves the pertinence and effectiveness of the annual inspection of new energy vehicles. This will help promote the healthy development of the new energy vehicle industry and ensure the driving safety of car owners.

[0035] Figure 1 FIG. 1 is a schematic diagram of an implementation environment of vehicle detection according to an exemplary embodiment of the present application. Figure 1 As shown, during the inspection process of the vehicle 110, the identity identifier corresponding to the vehicle can be obtained through the server 120, and the brand, model, battery brand, battery type, drive motor manufacturer, etc. corresponding to the vehicle can be determined through the identity identifier. Then, it can be determined whether the vehicle has any modification items based on the vehicle information and the modification items can be recorded. Then, the appearance of the vehicle is inspected. After the appearance inspection is completed, the server 120 further performs an electrical safety inspection on the battery of the vehicle, and the server 120 establishes a communication connection with the on-board automatic diagnostic system to receive the vehicle chassis test data reported by the on-board automatic diagnostic system through the communication connection, and then the server 120 can further integrate the vehicle chassis test data, electrical safety inspection data, appearance data and the vehicle's identity identifier to generate a test report for the vehicle.

[0036] in, Figure 1The server 120 shown may be, for example, an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms, and is not limited here. The vehicle 110 may communicate with the vehicle 110 via wireless networks such as 3G (third generation mobile information technology), 4G (fourth generation mobile information technology), and 5G (fifth generation mobile information technology), and is not limited here.

[0037] Traditionally, the annual inspection information of vehicles is in the form of a paper label attached to the front windshield of the vehicle's cab. The traffic management department can understand the annual inspection status of the vehicle by identifying the label, so as to achieve the purpose of recording the annual inspection information of the vehicle.

[0038] However, with the vigorous development of new energy vehicles in my country, the market share of new energy vehicles is also increasing year by year. Although the safety of new energy vehicles is not inferior to traditional fuel vehicles, many users are still worried about their safety. Therefore, annual inspections of new energy vehicles can effectively reduce the probability of accidents. How to detect new energy vehicles is a technical problem that needs to be solved urgently.

[0039] The above-mentioned problems are generally applicable in common scenarios. To solve these problems, the embodiments of the present application respectively propose a vehicle detection method, a vehicle detection device, an electronic device, a computer-readable storage medium, and a computer program product, which will be described in detail below.

[0040] See also Figure 2 , Figure 2 is a flow chart of a vehicle detection method shown in an exemplary embodiment of the present application. The method can be applied to Figure 1 The implementation environment shown is specifically executed by the server 120 in the implementation environment. It should be understood that the method can also be applied to other exemplary implementation environments and be specifically executed by devices in other implementation environments. This embodiment does not limit the implementation environment to which the method is applicable.

[0041] like Figure 2 As shown, in an exemplary embodiment, the vehicle detection method includes at least steps S210 to S240, which are described in detail as follows:

[0042] Step S210, obtaining identity information corresponding to the vehicle to be detected, and determining vehicle information corresponding to the vehicle to be detected based on the identity information.

[0043] Specifically, the vehicle identification number (VIN) corresponding to the vehicle can be obtained. Each vehicle has a unique VIN code, which can be used to confirm the vehicle's brand, model, production date, and place of origin. It is like the "ID card" of the vehicle and is the key to vehicle identification. Through the VIN code, the vehicle's historical records can be queried, including whether there are accident records, maintenance records, maintenance conditions, etc. The VIN code can also be used to query the exact model and specifications of vehicle accessories, making it convenient for car owners or repair shops to purchase the correct accessories. This uniqueness ensures the correct matching of accessories and improves the accuracy of repairs. The basic information of the vehicle can then be determined through the vehicle's VIN code, such as vehicle brand, model, battery brand, battery type, drive motor manufacturer, drive motor type, vehicle quality, and other information. The vehicle information of the vehicle can then be authenticated and tested item by item, and if there are any modifications, they can be updated to the corresponding server.

[0044] Step S220: If the vehicle information authentication is passed and the appearance data collection of the vehicle to be detected is completed, the battery status of the vehicle to be detected is obtained.

[0045] Specifically, after the vehicle information authentication record is completed, the vehicle appearance inspection can be started, such as checking whether there are scratches on the body, whether the brand type identification of the vehicle is normal, whether the lighting is normal, whether the tire is damaged, etc. After the appearance data collection is completed, the battery status of the vehicle is further obtained.

[0046] Exemplarily, when the vehicle information authentication is passed and the appearance data collection of the vehicle is completed, a series of technical measures can be taken to obtain the battery status of the vehicle. The battery status usually includes information such as power, voltage, current, health status (such as SOH, i.e., State of Health), and whether there is a fault. This information is crucial for evaluating the performance of the vehicle and predicting possible problems. For example, a professional car diagnostic tool (such as an OBD-II scanner) can be used to connect to the vehicle's diagnostic system through the vehicle's OBD-II interface. This interface is usually located under or near the driver's side dashboard. Through the diagnostic equipment, the vehicle's control unit (ECU) can be accessed and the relevant data of the battery can be requested to be sent. This data may include the current voltage, current, power percentage, and battery health status. Once the battery data is obtained from the vehicle system, the diagnostic equipment or software on the computer can be used to analyze and interpret the data. For example, it can be checked whether the battery voltage is within the normal range, whether the current has abnormal fluctuations, and whether the power is sufficient.

[0047] Step S230, completing the electrical safety test of the vehicle to be tested based on the battery status, and establishing a communication connection with the on-board automatic diagnosis system of the vehicle to be tested.

[0048] Specifically, when completing the vehicle electrical safety test based on the battery status, you first need to ensure that the battery itself is in good condition, because the battery is one of the core components of the vehicle's electrical system and is responsible for providing power support for the vehicle's electrical system. Once the battery status is confirmed (such as sufficient power, stable voltage, no faults, etc.), further electrical safety testing can be performed.

[0049] Among them, electrical safety testing usually includes the following aspects: Circuit system inspection: Check the vehicle's circuit system, including components such as wires, connectors, fuses and relays, to ensure that they are not damaged, aged or in poor contact. This helps prevent electrical faults such as short circuits and open circuits. Electrical component testing: Test various electrical components on the vehicle, such as lights, horns, wipers, air conditioning systems, etc., to ensure that they can work properly. Failure of these components may affect driving safety or the normal use of the vehicle. Charging and discharging tests: For the battery itself, in addition to checking its current state, charging and discharging tests can also be performed to evaluate its performance and health. These tests can reveal key parameters such as the battery's capacity and internal resistance, thereby helping to predict its service life and potential problems. Grounding system inspection: Check the vehicle's grounding system to ensure that all electrical components are properly grounded. Poor grounding may cause the electrical system to work unstably or fail.

[0050] Step S240, receiving chassis test data of the vehicle reported by the on-board automatic diagnosis system through a communication connection, and generating a test report of the vehicle to be tested based on the chassis test data, electrical safety test, appearance data and identity identification.

[0051] Specifically, chassis test data: These data usually include performance parameters and test results of suspension systems, brake systems, steering systems, etc. Chassis testing is essential for evaluating the safety and handling of vehicles. Electrical safety test data: Including battery status, circuit system inspection results, electrical component test conditions, grounding system inspection, etc., these data reflect the health and safety of the vehicle's electrical system. Appearance data: The collected vehicle appearance information, such as body damage, paint condition, tire wear, etc., is also important for evaluating the overall condition and potential value of the vehicle. Identity identification: The vehicle's VIN code (vehicle identification number) or other unique identifier is used to confirm the identity of the vehicle and trace its history. Conduct in-depth analysis of the various data received to identify any abnormalities, potential problems or non-compliance with standards. Compare chassis test data with vehicle manufacturer specifications or industry standards to evaluate whether the vehicle's performance meets the standards. Comprehensive electrical safety test results to evaluate the safety and reliability of the vehicle's electrical system. Combined with appearance data, a comprehensive evaluation of the overall condition of the vehicle is made. Based on the analysis results, a detailed test report is written. The report should include basic information about the vehicle (such as VIN number, model, production date, etc.), inspection time, inspection personnel, etc. The inspection contents and results of chassis test, electrical safety test, appearance inspection, etc. should be listed one by one. Any problems or abnormalities found should be described in detail and possible explanations or suggestions should be given.

[0052] In this embodiment, through automated and digital means (such as rapid vehicle information confirmation based on identity information, automatic detection of battery status, communication connection with the on-board automatic diagnostic system, etc.), the time and error rate of manual operation are greatly reduced, and the overall efficiency and accuracy of the detection process are improved. Combining chassis test data, electrical safety test results, appearance data, and vehicle identity information, a comprehensive and detailed vehicle inspection report can be generated. This comprehensive assessment not only covers the main mechanical and electrical systems of the vehicle, but also takes into account the identity information and appearance of the vehicle, providing comprehensive vehicle status information for car owners and maintenance personnel.

[0053] Further, based on the above embodiments, please refer to Figure 3 In one of the exemplary embodiments provided in the present application, the specific implementation process of the above vehicle detection method may also include steps S310 to S330, which are described in detail as follows:

[0054] Step S310, determining chassis-related parameters corresponding to the vehicle to be detected based on the identity identifier;

[0055] Step S320, adjusting the operating parameters of the chassis test equipment based on the chassis related parameters to obtain an adjusted chassis test equipment;

[0056] Step S330, establishing a communication connection between the adjusted chassis test equipment and the on-board automatic diagnostic system.

[0057] Specifically, the tire specifications, wheel spacing, wheelbase and other parameters of the vehicle can be determined according to the vehicle identification to adjust the operating parameters of the chassis test equipment. Among them, the tire specification is a set of numbers and letters that describe the tire size and performance characteristics. It usually includes information such as tire width, aspect ratio, tire type, rim diameter, load index and speed level. For example, in the tire specification "195 / 55R1685V", 195 means that the tire width is 195 mm, 55 means the aspect ratio (that is, the percentage of the tire section height to the width), R means radial tire, 16 means the rim diameter is 16 inches, 85 is the load index, and V is the speed level. Tire specifications are an important basis for tire selection, replacement and maintenance. Wheel spacing, more precisely, wheel hole spacing or pitch circle diameter (PCD), refers to the distance between the centers of two adjacent fixing bolt holes on the inner ring of the wheel hub. This parameter is crucial to ensure that the wheel is properly installed on the vehicle. Different vehicles and wheel hub designs may have different wheel hole spacings, so special attention needs to be paid when selecting and installing wheels. The value of the wheel hub hole spacing is usually expressed in millimeters, such as "5X114.3" means that the wheel hub has five bolt holes, and the center distance between two adjacent holes is 114.3 mm. The wheelbase refers to the distance between the midpoints (or axles) of two adjacent wheels on the same side of the vehicle, that is, the distance from the center of the front axle to the center of the rear axle. Wheelbase is one of the important parameters of vehicle design and performance, which affects the vehicle's stability, handling, ride comfort and space layout. Vehicles of different models and uses often have different wheelbase designs to meet different usage requirements.

[0058] Exemplarily, the input identity is used to query the corresponding vehicle parameters in the vehicle information database. These parameters include but are not limited to tire specifications, wheel hub spacing (pitch diameter), wheelbase, vehicle weight, engine type, etc. According to the extracted parameters such as tire specifications, wheel hub spacing and wheelbase, the chassis test equipment is analyzed for adjustments that need to be made. For example, the tire specifications determine the road friction coefficient and tire load capacity that the test equipment needs to simulate; the wheel hub spacing and wheelbase affect the positioning accuracy and test range of the test equipment. According to the analysis results, the operating parameters of the chassis test equipment are adjusted accordingly. This may include adjusting the size, shape and height of the test platform to accommodate vehicles with different wheelbases; adjusting the specifications and air pressure of the test tires to match the tires of the actual vehicle; and adjusting the sensors and control systems of the test equipment to ensure the accuracy and reliability of the test. After completing the adjustment of the equipment parameters, necessary verification and testing are carried out to ensure that the adjusted chassis test equipment can accurately simulate the driving conditions and performance of the actual vehicle.

[0059] In this embodiment, the operating parameters of the chassis test equipment are adjusted according to the chassis-related parameters, which can ensure that the test equipment operates in the optimal state, thereby improving the accuracy and reliability of the test results. By establishing a communication connection with the on-board automatic diagnostic system (OBD system), real-time transmission and automatic analysis of test data can be achieved, further improving the automation and intelligence level of the test. Moreover, this automated test process reduces human intervention and errors, and improves the consistency and repeatability of the test.

[0060] Further, based on the above embodiments, please refer to Figure 4 In one of the exemplary embodiments provided in the present application, after the communication connection between the adjusted chassis test equipment and the on-board automatic diagnostic system is established, the specific implementation process of the above vehicle detection method may further include step S410 and step S420, which are described in detail as follows:

[0061] Step S410, fixing the adjusted chassis test equipment and the vehicle to be tested, and controlling the vehicle to be tested to run at a preset speed;

[0062] Step S420, obtaining the operating condition information corresponding to the vehicle to be detected at a preset vehicle speed, so as to obtain the chassis test data of the vehicle to be detected based on the operating condition information through the vehicle automatic diagnosis system.

[0063] Specifically, ensure that the chassis test equipment is firmly connected to the vehicle through appropriate fixtures, brackets or other fixtures. This can prevent the equipment or vehicle from moving or shifting during the test, thereby ensuring the accuracy and safety of the test. Adjust the relative position between the chassis test equipment and the vehicle to ensure that the test equipment can accurately simulate and measure the performance of the vehicle chassis under different working conditions. This may include adjusting parameters such as the height, angle and position of the test platform. According to the test requirements, set a preset vehicle speed in the chassis test equipment or vehicle control system. This speed can be constant or change according to a certain pattern to simulate different working conditions in actual driving.

[0064] During the operation of the vehicle, the vehicle's operating information is monitored and recorded in real time through on-board sensors and chassis test equipment. This information may include vehicle speed, acceleration, braking force, steering angle, suspension system status, etc., which reflect the actual performance of the vehicle under different working conditions. The on-board automatic diagnostic system (OBD system) can read and analyze the data of various vehicle systems in real time, including the engine, transmission system, braking system, suspension system, etc. During the vehicle's operation at the preset speed, the OBD system will continue to collect data related to chassis performance, such as engine speed, wheel speed, ABS working status, etc. The data obtained by the on-board automatic diagnostic system is synchronized and matched with the data of the chassis test equipment, and the data is processed and analyzed by data processing and analysis software. This can reveal the performance of the vehicle chassis under different working conditions, such as the response speed of the suspension system, the effectiveness of the braking system, the stability of the steering system, etc. Based on the processed and analyzed data, the performance of the vehicle chassis is comprehensively evaluated. This may include comparison with standard values ​​or reference values ​​to determine whether the performance of the vehicle chassis meets the requirements or what problems exist.

[0065] In this embodiment, by firmly fixing the chassis test equipment to the vehicle to be tested, the test error caused by vehicle shaking or equipment looseness can be effectively avoided, ensuring the stability and reliability of the test data. By obtaining the working condition information at the preset vehicle speed, the various performances of the vehicle chassis system can be comprehensively evaluated, including the response and stability of the suspension system, braking system, steering system, etc. This comprehensive evaluation helps to discover potential performance problems or hidden faults, and provides strong support for subsequent repairs and maintenance.

[0066] Further, based on the above embodiments, please refer to Figure 5 In one of the exemplary embodiments provided in the present application, the specific implementation process of the above vehicle detection method may also include steps S510 to S530, which are described in detail as follows:

[0067] Step S510, obtaining multiple operating condition information corresponding to the vehicle to be detected at a preset speed according to a first preset frequency;

[0068] Step S520, generating chassis diagnostic data of the vehicle to be tested based on multiple operating condition information through the on-board automatic diagnostic system;

[0069] Step S530: obtaining a chassis test report of the vehicle to be tested based on the chassis diagnostic data.

[0070] Specifically, first, it is necessary to determine a suitable sampling frequency, namely the first preset frequency, for regularly acquiring working condition information from the vehicle and chassis test equipment. This frequency should be high enough to accurately capture the dynamic changes of the vehicle under different working conditions, but at the same time, the data processing and storage capabilities should also be taken into account. According to the set first preset frequency, the working condition information is regularly collected from the vehicle sensors, chassis test equipment and other related systems. These working condition information may include multiple parameters such as vehicle speed, acceleration, braking force, steering angle, suspension system status, wheel speed, engine speed, etc. : The working condition information obtained from each sampling is recorded and timestamped for subsequent data processing and analysis. The working condition information obtained from multiple samplings is integrated to form a complete data set. This data set contains the detailed performance of the vehicle under different working conditions. The integrated data is parsed using the data processing capabilities of the on-board automatic diagnostic system (OBD system). The OBD system can identify and extract data directly related to chassis performance, such as the response speed of the suspension system, the effectiveness of the braking system, the stability of the steering system, etc. Based on the parsed data, chassis diagnostic data is generated. These data may include performance indicators, abnormal conditions, potential failures and other information of various chassis systems.

[0071] The chassis diagnostic data is then evaluated to determine whether the performance of the vehicle chassis meets the preset standards or requirements. This may include comparison with standard values ​​provided by the manufacturer, industry standards or regulatory requirements. Based on the results of the data evaluation, a chassis test report is written. The report should include the test purpose, test methods, test conditions, test data, evaluation results, and possible improvement suggestions. The evaluation results should clearly indicate whether the performance of the vehicle chassis meets the standards, as well as any problems or potential risks.

[0072] In this embodiment, more information about the working condition of the vehicle at different time points can be captured by sampling multiple times (according to the first preset frequency), thereby avoiding the contingency and error that may be caused by single sampling. The comprehensive analysis of multiple working condition information can more comprehensively reflect the working state of the vehicle chassis system at the preset vehicle speed, and improve the accuracy and reliability of the test data.

[0073] Further, based on the above embodiments, please refer to Figure 6 In one of the exemplary embodiments provided in the present application, the specific implementation process of the above vehicle detection method may also include steps S610 to S630, which are described in detail as follows:

[0074] Step S610, establishing a connection between the vehicle to be detected and the charging detection device;

[0075] Step S620, performing electrical safety testing on the vehicle to be tested based on the charging testing equipment;

[0076] Step S630, obtaining status data of the battery of the vehicle to be tested during the electrical safety test, where the status data includes at least one of potential, capacity, voltage and temperature.

[0077] Specifically, after the appearance inspection of the vehicle is completed, the charging equipment can be used to perform AC / DC and electrical safety inspections on the vehicle's batteries. For example, the charging inspection equipment can be used to collect relevant data on the vehicle, including: the maximum temperature of the power battery, the maximum voltage of the single battery, the extreme difference of the single battery voltage, the total voltage indication of the BMS, the insulation resistance of the DC charging socket, the potential balance between the outer casing and the electrical platform, the insulation resistance of the AC charging socket, the potential balance between the outer casings, and other data.

[0078] Exemplarily, ensure that the charging detection device is properly installed and in working condition, and check whether its power supply, communication interface (such as CAN bus, Bluetooth, Wi-Fi, etc.) and necessary sensors (such as current sensor, voltage sensor, temperature sensor) are intact. Check whether the vehicle is parked in a suitable location for charging, and confirm that the vehicle power is turned off, but the vehicle electrical system (such as 12V battery) should be in a detectable state. Use a charging cable to connect the charging interface of the charging detection device to the charging interface of the vehicle. Charging cables or adapters of different specifications may be required for different models. In some cases, it may be necessary to communicate through the vehicle's OBD-II interface or a dedicated communication port, in which case the corresponding data cable should be connected. Start the electrical safety detection program on the charging detection device. The program usually includes insulation resistance detection, ground continuity detection, overcurrent protection detection, etc. During the electrical safety detection process or after the detection is completed, start the battery status data acquisition program. Through the sensors on the charging detection device or communicating with the vehicle's OBD-II interface, the battery's potential, capacity, voltage, temperature and other status data are collected in real time.

[0079] In this embodiment, the battery status data is obtained in real time during the electrical safety detection process, which can immediately reflect the working status and performance of the battery. This real-time performance ensures the accuracy of the detection results, helps to discover and solve problems in a timely manner, and the obtained battery status data is an important basis for repair and maintenance. Furthermore, based on this data, maintenance personnel can determine whether the battery needs to be replaced, whether the charging system needs to be adjusted, etc., so as to formulate a scientific and reasonable maintenance plan.

[0080] Further, based on the above embodiments, please refer to Figure 7 In one of the exemplary embodiments provided in the present application, the specific implementation process of the above vehicle detection method may further include step S710 and step S720, which are described in detail as follows:

[0081] Step S710, converting the state data into a corresponding identification code based on a mapping relationship between the state data and the identification code, where the identification code includes a service identification code and a service identification code;

[0082] Step S720, generating a CAN message based on the service identification code and the service identification code, so as to determine the electrical safety test result corresponding to the vehicle to be tested based on the CAN message.

[0083] Specifically, the status data can be converted into the corresponding identification code according to the mapping relationship between the status data and the identification code. In the "New Energy Vehicle Operation Safety Performance Inspection Procedure", regarding the specific content of SID (Service Identifier) ​​and PID (Parameter Identifier), all possible CAN (Controller Area Network) message contents and their SID and PID combinations are usually not directly listed. This is because the content of the CAN message is highly dependent on the specific vehicle manufacturer, model, and communication protocol used.

[0084] Among them, SID (Service Identifier) ​​SID is used to identify specific service requests or commands in vehicle communication, especially diagnostic communication. It is a code used to identify different diagnostic services and is usually used in vehicle diagnostic communication protocols, such as UDS (Unified Diagnostic Services) and OBD-II (On-Board Diagnostics) systems. Each SID corresponds to a specific service function, such as reading data, clearing fault codes, executing specific control commands, etc. When technicians use diagnostic tools to communicate with the vehicle's ECU (Electronic Control Unit), they send requests with specific SIDs to obtain the required information or perform specific operations. PID (Parameter Identifier) ​​PID is used to identify specific data or parameters that can be accessed and transmitted through network communication protocols. In the automotive field, PID is commonly found in OBD systems and is used to represent various sensor data, fault codes, vehicle status and other information of the vehicle. For example, in the OBD-II protocol, PID is used to represent the code for vehicle status information such as engine speed, vehicle speed, and coolant temperature. With the appropriate diagnostic tools or equipment, technicians can obtain data related to the vehicle's operating status or fault by querying specific PIDs, which is very important for fault diagnosis and repair.

[0085] Exemplarily, in this process, various status data of the vehicle (such as battery voltage, motor temperature, brake system status, etc.) are mapped to corresponding identification codes. These identification codes include service identification codes (SID) and parameter identification codes (PID). SID is used to identify a specific service or request type, while PID is used to identify specific parameters or data under the service or request. The vehicle's ECU (electronic control unit) or diagnostic system will convert the real-time collected status data into corresponding SID and PID according to the preset mapping relationship. In this way, each status data point has a unique SID and PID corresponding to it, which is convenient for transmission and identification in the CAN network. Once the status data is converted into SID and PID, they will be encapsulated into one or more CAN messages. CAN messages are a standardized data frame used to transmit information on the CAN network inside the vehicle. Each CAN message contains an identifier (ID, which can be regarded as a combination of SID and PID or SID alone, depending on the protocol design), data length, and data field.

[0086] The receiving end (such as a diagnostic tool, vehicle dashboard, or central control unit) parses the received CAN message and identifies the specific status data based on the SID and PID. This status data is then used to evaluate the vehicle's electrical safety performance. For example, if the battery voltage is below the safety threshold or the braking system is in an abnormal state, the system will issue a warning or take appropriate safety measures.

[0087] In this embodiment, by establishing a mapping relationship between the status data and the identification code, data standardization and unification are achieved. This standardization process facilitates the exchange and sharing of data between different systems or devices, and improves the readability and maintainability of the data. In addition, by transmitting data through CAN messages, information can be quickly transmitted in the internal network of the vehicle. After converting the status data into an identification code and generating a CAN message, the redundancy and delay of data transmission can be significantly reduced, and the efficiency and real-time performance of data transmission can be improved.

[0088] Further, based on the above embodiments, please refer to Figure 8 In one of the exemplary embodiments provided in the present application, the specific implementation process of the above vehicle detection method may further include step S810 and step S820, which are described in detail as follows:

[0089] Step S810, collecting CAN messages at a second preset frequency within a preset period, where the second preset frequency is lower than the first preset frequency;

[0090] Step S820, determining the electrical safety test result corresponding to the vehicle to be tested based on the status data corresponding to the multiple CAN messages collected within a preset period.

[0091] In some feasible embodiments, a diagnostic CAN message can only read one data, so it is necessary to periodically send diagnostic messages to read the corresponding data. Therefore, the diagnostic message can be sent according to the second preset frequency to read the corresponding CAN message through the sent diagnostic message. Since the real-time requirement for vehicle speed detection is relatively high, the first preset frequency for collecting vehicle speed is higher than the second preset frequency for collecting electrical status data. For example, because a diagnostic message can only read one data. Therefore, it is necessary to periodically send diagnostic messages to read the corresponding data, and the interval between each two sent diagnostic messages is 200ms. In addition, the real-time requirement for vehicle speed is relatively high, so the message interval for obtaining vehicle speed is set to 50ms. After receiving the diagnostic message, the vehicle-side ECU replies with data, and the data is forwarded to the PAD end through the OBD device. After receiving the data, the PAD decodes it into data with practical significance. Finally, the data is reported to the server.

[0092] For example, in the vehicle diagnostic system, the CAN (Controller Area Network) bus is widely used for communication between various control units (ECU, Electronic Control Unit) inside the vehicle. Since a single diagnostic CAN message can usually only carry a limited amount of information, that is, only one specific data can be read, in order to fully monitor and diagnose the vehicle status, it is necessary to periodically send multiple different diagnostic request messages, and receive and process the responses to these messages accordingly. The vehicle's control unit (ECU) will respond to these diagnostic requests and send CAN messages containing the required data. The system needs to collect these response messages at a lower second preset frequency within a preset period (for example, a few seconds or minutes). Although the second preset frequency is lower than the first preset frequency, it is still sufficient to capture important state changes. The multiple CAN messages collected within the preset period contain status data of different systems and components of the vehicle. These data need to be parsed, integrated and compared to form a comprehensive assessment of the electrical safety status of the vehicle. Based on the results of the above data processing, the system can generate electrical safety detection results. These results may include but are not limited to: whether a system is operating normally, whether there is a potential fault, whether maintenance or repair is required, etc.

[0093] In this embodiment, by collecting multiple CAN messages within a preset period, the status data of the vehicle electrical system at multiple time points can be obtained. The comprehensive analysis of these data points can more comprehensively reflect the overall operating status of the electrical system, and can timely discover and deal with potential safety hazards, reducing the risk of vehicle accidents caused by electrical failures.
