Technical Field

[0001] The present application belongs to the field of vehicle detection technology, and in particular, relates to a detection method, a detection system, a terminal device and a computer-readable storage medium. Background Art

[0002] As automotive technology develops and the complexity of automotive electronic control systems increases, more efficient and accurate methods are needed to detect vehicle faults.

[0003] In the related art, before testing a vehicle, a dependent condition is usually required, that is, the correct execution of the test can only be ensured when the dependent condition is met. The detection device sends multiple instructions to the vehicle control system to obtain the working condition data corresponding to the dependent condition, and determines whether the obtained working condition data meets the dependent condition. In the above implementation, multiple data interactions are usually required between the detection device and the vehicle control system, resulting in low detection efficiency. Summary of the invention

[0010] In an embodiment of the present application, the system identifies the preset conditions (dependent conditions) corresponding to the detection request sent by the detection device, and obtains the working condition data corresponding to the preset conditions. When it is determined that the working condition data meets the preset conditions, the detection task corresponding to the detection request is executed. In other words, when the detection request needs to detect the preset conditions, the working condition data corresponding to the preset conditions is obtained through the vehicle system, and it is determined whether the working condition data meets the preset conditions. This solves the problem in the related art that multiple instructions are sent from the detection device to the vehicle control system to obtain the working condition data corresponding to the dependent conditions, and it is determined whether the obtained working condition data meets the dependent conditions. Multiple data interactions are usually required between the detection device and the vehicle control system, which can reduce the number of data interactions between the detection device and the vehicle control system and improve detection efficiency.

[0011] In a possible implementation manner of the first aspect, obtaining a preset condition corresponding to the detection request includes:

[0012] After monitoring the detection request, determining whether the detection request includes the first identifier;

[0013] If the detection request includes the first identifier, a preset condition corresponding to the detection request is obtained.

[0014] In the embodiment of the present application, by checking the identifier (first identifier), the system can screen out specific requests and only process those requests with the corresponding identifier, thereby improving the efficiency and accuracy of processing.

[0017] If the first identifier exists in the preset database, the first detection condition corresponding to the first identifier in the preset database is determined as the preset condition.

[0018] In the embodiment of the present application, by checking the identifiers in the preset database, the system can accurately identify specific conditions, thereby ensuring that only requests that meet the preset conditions are processed.

[0019] In a possible implementation manner of the first aspect, the preset condition includes a plurality of first sub-conditions; the operating condition data includes data corresponding to each first sub-condition;

[0022] If there is a first sub-condition that is not met, it is determined that the operating condition data does not meet the preset condition;

[0023] If all the first sub-conditions are met, it is determined that the operating condition data meets the preset conditions.

[0024] In the embodiment of the present application, by checking the first sub-conditions one by one, the system can accurately determine whether the operating condition data meets all preset conditions, and the preset conditions can be configured according to actual needs, so that the system can adapt to different inspection standards and complex conditions.

[0033] A first identifier is generated according to a third detection condition.

[0034] In the embodiment of the present application, by considering different sub-condition combinations of the second detection condition, the system can generate multiple possible detection conditions and generate different identifiers based on the multiple possible detection conditions, thereby increasing the flexibility of processing detection tasks.

[0035] In a possible implementation manner of the first aspect, the method further includes:

[0036] If the operating condition data does not meet the preset conditions, the result that the operating condition data does not meet the preset conditions is returned to the detection device, and the detection task corresponding to the detection request is refused to be executed.

[0037] In an embodiment of the present application, results that do not meet the conditions are returned to the detection device, so that the device operator can understand the situation in a timely manner and take corresponding measures, thereby improving the user experience. In addition, the detection task is not performed if the preset conditions are not met, thereby reducing system instability or erroneous operations that may be caused by erroneous data.

[0051] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0053] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0054] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0055] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0056] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0057] As automotive technology develops and the complexity of automotive electronic control systems increases, more efficient and accurate methods are needed to detect vehicle faults.

[0058] In the related art, before testing a vehicle, a dependent condition is usually required, that is, the correct execution of the test can only be ensured when the dependent condition is met. The detection device sends multiple instructions to the vehicle control system to obtain the working condition data corresponding to the dependent condition, and determines whether the obtained working condition data meets the dependent condition. In the above implementation, multiple data interactions are usually required between the detection device and the vehicle control system, resulting in low detection efficiency.

[0059] In order to solve the problems arising in the above-mentioned related technologies, an embodiment of the present application provides a detection method. In the present application, multiple dependency conditions can be customized and sent to the electronic control unit (ECU) of the vehicle. The vehicle ECU will store and integrate these multiple conditions to generate a dependency ID. When executing the detection task, if there is a dependency condition, the corresponding dependency ID and the detection task can be sent to the vehicle ECU together. The vehicle ECU will automatically determine whether each condition is met based on the dependency ID. If not, it returns that the condition is not met. If it is met, the detection task is directly executed and the result is returned. In this way, it is possible to reduce the repeated sending of instructions to judge the dependency items and improve the detection efficiency.

[0060] See also Figure 1 , is a flow chart of the detection method provided in the embodiment of the present application. As an example but not a limitation, the method may include the following steps:

[0061] S101, when a detection request sent by a detection terminal is monitored, a preset condition corresponding to the detection request is obtained.

[0062] In the embodiment of the present application, the detection terminal refers to a device with detection function, which is used to monitor the environment, physical state, equipment performance, etc. In the process of detecting or diagnosing the vehicle, the detection terminal can be an on-board diagnostic system (OBD) diagnostic tool, which can read the vehicle's fault code and real-time data stream through the vehicle's OBD interface.

[0063] After the detection device (detection terminal) sends a detection request to the vehicle control system, when the system receives the detection request, it will extract the preset conditions associated with the request. Preset conditions can also be called dependent conditions, which refer to a series of parameters, rules or standards that must be met in order to perform the detection task. For example, the preset conditions are that the ignition switch must be turned on, the vehicle speed is 0, and the steering wheel must be in the initial state. These preset conditions are parameters that must be met before performing the detection task.

[0064] In one embodiment, see Figure 2 , is a schematic diagram of the process of obtaining the preset conditions provided in the embodiment of the present application Figure 1 ,like Figure 2As shown, step S101 includes:

[0065] S201, after monitoring a detection request, determining whether the detection request includes a first identifier;

[0066] In an embodiment of the present application, after receiving a detection request, the system (vehicle ECU) needs to check whether the request contains a specific identifier, and this identifier (first identifier) ​​is used to determine whether a preset condition is required in the pre-detection.

[0067] The first identifier is equivalent to an ID, which is used to identify a specific detection task or request. If the detection request contains this ID, and it is detected that the dependency check flag is added in the detection request, it means that the request is rejected when the preset conditions are not met. If the detection request does not contain the first identifier, and the dependency check flag is not added, it means that the request does not need to be tested for preset conditions, and the system can directly execute the request. Among them, the dependency check flag indicates that a specific identifier is included in the message or data structure of the detection request, which is used to indicate whether the system should perform certain additional (preset condition) checks.

[0068] S202: If the detection request includes the first identifier, obtain a preset condition corresponding to the detection request.

[0069] In an embodiment of the present application, when processing a detection request, the system checks whether the request contains a specific identifier (first identifier). If the identifier is detected, the system will then obtain preset conditions related to this request to verify whether these conditions are met before performing the detection.

[0070] In the above method, in the embodiment of the present application, by checking the identifier (first identifier), the system can filter out specific requests, so that only those requests with the corresponding identifier are processed, thereby improving the efficiency and accuracy of processing.

[0071] In one embodiment, see Figure 3 , is a schematic diagram of the process of obtaining the preset conditions provided in the embodiment of the present application Figure 2 ,like Figure 2 As shown, step S202 includes:

[0072] S301, detecting whether a first identifier exists in a preset database; wherein the preset database includes a plurality of identifiers and a first detection condition corresponding to each identifier.

[0073] In the embodiment of the present application, the preset database is a data storage system stored in the vehicle, which contains various identifiers and their corresponding detection conditions. This database can be a file system, a data structure in memory, or any other storage solution suitable for use in a vehicle environment.

[0074] After the system detects that the detection request sent by the detection device contains the first identifier, it needs to check whether the first identifier and the first detection condition corresponding to each identifier exist in the preset database stored in the vehicle. If the system needs to implement logic to perform a query on the preset database, this may involve writing a query statement or using a database query language such as SQL. When the system determines that the first identifier exists in the database, it needs to parse the detection condition (first detection condition) associated with the identifier, which involves extracting condition data from the database and converting them into executable inspection steps.

[0075] S302: If the first identifier exists in the preset database, determine the first detection condition corresponding to the first identifier in the preset database as the preset condition.

[0076] In the embodiment of the present application, when the system detects the first identifier in the database and the detection conditions corresponding to the first identifier, these conditions are regarded as preset conditions. Before performing any other operations, the system must ensure that these preset conditions are met.

[0077] Exemplarily, the first detection condition corresponding to the first identifier in the preset database is that the ignition switch is turned on, the vehicle speed is 0, and the steering wheel is in the initial state. In this case, the ignition switch is turned on, the vehicle speed is 0, and the steering wheel is in the initial state are determined as preset conditions. Before executing the detection task, it is first checked whether the preset conditions are met.

[0078] In the above method, by checking the identifiers in the preset database, the system can accurately identify specific conditions, thereby ensuring that only requests that meet the preset conditions are processed.

[0079] S102, obtaining operating condition data corresponding to preset conditions.

[0080] In the embodiment of the present application, as in the above example, the preset conditions are that the ignition switch is turned on, the vehicle speed is 0, and the steering wheel is in the initial state. The operating condition data refers to the data of the current state of the vehicle, such as the engine state, vehicle speed, steering wheel position, etc. corresponding to the preset conditions.

[0081] Specifically, the ECU in the vehicle control system is an electronic device in the vehicle that is responsible for controlling specific functions (such as the engine, transmission system, braking system, etc.). The ECU usually collects data through sensors, actuators, and other ECUs. The ECU can obtain the status of the ignition switch by querying the vehicle's power management system, which involves communication with the power control module (PCM) to determine whether the ignition switch is turned on; the ECU can obtain vehicle speed data through the vehicle's sensors (such as speed sensors). These sensors send vehicle speed information to the ECU so that the ECU can check whether the vehicle speed is 0; the ECU can obtain the status of the steering wheel through the steering wheel position sensor. These sensors can detect the angle of the steering wheel and pass it to the ECU so that the ECU can determine whether the steering wheel is in the initial state. After receiving this data, the ECU will process and verify it to ensure that the preset conditions are met.

[0082] In one embodiment, the preset condition includes a plurality of first sub-conditions; the operating condition data includes data corresponding to each first sub-condition, and after obtaining the operating condition data corresponding to the preset condition in step S102, the method further includes:

[0083] Determine whether each first sub-condition is satisfied based on the data corresponding to each first sub-condition; if there is a first sub-condition that is not satisfied, determine that the operating condition data does not meet the preset condition; if all first sub-conditions are satisfied, determine that the operating condition data meets the preset condition.

[0084] In the embodiment of the present application, the preset condition is composed of multiple smaller sub-conditions (first sub-conditions), which together define the complete conditions that the system needs to meet. For example, in the preset conditions in the above example, the ignition switch must be turned on, the vehicle speed is 0, and the steering wheel must be in the initial state. The first sub-conditions are respectively the ignition switch is turned on, the vehicle speed is 0, and the steering wheel is in the initial state. The data corresponding to the first sub-condition is the state data of the ignition switch, the vehicle speed data, and the angle data of the steering wheel (operating condition data) obtained by the ECU.

[0085] Specifically, the system includes a judgment logic for judging whether the entire operating condition data meets the preset conditions based on the verification of the first sub-condition. All sub-conditions can be looped through to compare whether the corresponding data in the operating condition data is consistent with the requirements of each first sub-condition. If the data meets the requirements of the sub-condition, the sub-condition is considered to be established. If any first sub-condition in the operating condition data is not satisfied, that is, the corresponding data does not meet the requirements of the sub-condition, then the entire operating condition data is considered to not meet the preset conditions. If all first sub-conditions in the operating condition data are satisfied, that is, the corresponding data points meet the requirements of the sub-conditions, then the operating condition data is considered to meet the preset conditions.

[0086] In the above method, by checking the first sub-conditions one by one, the system can accurately determine whether the operating data meets all preset conditions, and the preset conditions can be configured according to actual needs, so that the system can adapt to different inspection standards and complex conditions.

[0087] S103: If the operating condition data meets the preset conditions, the detection task corresponding to the detection request is executed to obtain the detection result.

[0088] In an embodiment of the present application, when the operating condition data meets the preset conditions, the system will trigger and execute the detection task corresponding to the corresponding detection request, which may involve starting a specific detection program, algorithm or test process. For example, the detection task is to read the vehicle's fault code and real-time data stream through the vehicle's OBD interface. After the vehicle's diagnostic system or sensor executes the detection task, the system collects and organizes the detection results.

[0089] S104, sending the detection results to the detection terminal.

[0090] In one embodiment, the vehicle's diagnostic system collects necessary detection data (such as fault codes) and packages them into a format suitable for transmission, which involves converting the data into a standardized message format such as JSON or XML, and may include encryption and security measures to ensure the integrity of the data during transmission. The vehicle needs to select a suitable communication protocol to send data, and different protocols have different transmission speeds, power consumption, and coverage.

[0091] For example, if the vehicle is far away from the detection terminal, it may be necessary to use cellular network communication. The vehicle sends the packaged data to the detection terminal through the wireless network, which may involve the use of a mobile data network such as 4G or 5G, or a direct connection using a Wi-Fi hotspot. The detection terminal may store the received data in a database for historical record analysis or trend prediction.

[0092] In the above method, when the detection request needs to detect the preset conditions, the operating condition data corresponding to the preset conditions is obtained through the vehicle system, and it is judged whether the operating condition data meets the preset conditions. This solves the problem that in the related technology, multiple instructions are sent to the vehicle control system by the detection device to obtain the operating condition data corresponding to the dependent conditions, and it is judged whether the acquired operating condition data meets the dependent conditions, and multiple data interactions are usually required between the detection device and the vehicle control system. This can reduce the number of data interactions between the detection device and the vehicle control system and improve the detection efficiency.

[0093] In one embodiment, see Figure 4 , is a schematic diagram of a process for generating a first identifier provided in an embodiment of the present application, such as Figure 4 As shown, the detection method also includes:

[0094] S401, obtaining a first request sent by a detection terminal, where the first request includes a second detection condition.

[0095] In the embodiment of the present application, the above-mentioned first identifier can be generated before the detection device (detection terminal) sends a detection request to the vehicle ECU. If the detection requirement requires the detection of a preset condition (second detection condition) first, the detection device sends the second detection condition corresponding to the detection task to the vehicle ECU to apply for a unique dependency ID (first identifier), and the detection device needs to send a request for a new dependency (first request) to the vehicle ECU, so that the vehicle ECU generates a unique dependency ID according to the second detection condition.

[0096] The first request mentioned above includes the judgment method for each dependent condition (second detection condition), and the method includes the data item code (Data Item Description, DID,) to be judged, the judgment method (0 equals, 1 is greater than, 2 is less than, 3 is in range), and the judgment value. For example, the DID of the vehicle speed is 0x0801, and the judgment method 0 means equal, and the judgment value is 0. Among them, DID is a code used to identify a specific data item, which usually includes the type and location information of the data item. In some standardized systems, such as the diagnostic communication protocol in the automotive industry, DID can help identify and access various data items of the vehicle.

[0097] S402: Generate a first identifier according to the second detection condition.

[0098] In the embodiment of the present application, a unique ID (first identifier) ​​is created according to the second detection condition to ensure that each detection condition has a unique identifier.

[0099] Specifically, the system needs to define the format of the ID (first identifier), including its length, components (such as numbers, letters, special symbols), and whether it needs to include a timestamp, sequence number, etc. According to the second detection condition, a suitable algorithm is selected, such as UUID, Snowflake algorithm, Leaf algorithm, etc., and ID generation is implemented according to the selected algorithm.

[0100] If the selected algorithm is the Snowflake algorithm, the steps for generating an ID according to the second detection condition can be: obtain the current timestamp and subtract a fixed offset (such as epoch time) to obtain the timestamp part; generate a unique working node ID based on the machine ID and data center ID; use a serial number generator to generate a serial number; combine these parts into a 64-bit integer as the ID.

[0101] In one embodiment, step S402 includes:

[0102] If the second detection condition includes multiple second sub-conditions, a third detection condition is generated according to any combination of A second sub-conditions among the multiple second sub-conditions, where 1≤A≤N, and N is the total number of second sub-conditions included in the second detection condition; and a first identifier is generated according to the third detection condition.

[0103] In the embodiment of the present application, the first identifier may be generated according to different combinations of multiple sub-conditions (second sub-conditions) in the detection condition (second detection condition).

[0104] Exemplarily, if the second detection condition includes: a. the engine is in an off state, b. the vehicle speed is 0, c. the vehicle brake is in a locked state, and d. the vehicle is in an unloaded state. a, b, c, and d are the second sub-conditions in the second detection condition, and the number N is the total number of the second sub-conditions, in this example N=4. The four second sub-conditions are arbitrarily combined into a third detection condition; for example, the third detection condition can be: a. the engine is in an off state, b. the vehicle speed is 0, c. the vehicle brake is in a locked state; a. the engine is in an off state, b. the vehicle speed is 0, c. the vehicle brake is in a locked state, etc. After the third detection conditions of the three combinations are sent to the vehicle ECU respectively, the vehicle ECU can generate three different first identifiers according to the three combinations.

[0105] In the above method, by considering different sub-condition combinations of the second detection condition, the system can generate multiple possible detection conditions and generate different identifiers according to the multiple possible detection conditions, thereby increasing the flexibility of processing detection tasks.

[0106] S403: Store the first identifier and the second detection condition in a preset database.

[0107] In the embodiment of the present application, the vehicle ECU needs to write logic to process the operation of storing the first identifier and the second detection condition in the preset database, which usually involves using SQL statements or other database operation languages ​​to perform insert operations, and the system executes the storage logic to store the first identifier and the second detection condition as records in the preset database. The storage operation may require processing details such as data format and data type conversion.

[0108] S404: Send the first identifier to the detection terminal.

[0109] In the embodiment of the present application, the vehicle ECU or software system executes the sending logic to send the first identifier to the detection terminal through the communication connection. This process may involve data serialization, encryption or other security measures.

[0110] In the above method, by generating a unique identifier, the system can easily identify and manage different detection conditions, improve data management efficiency, and help improve the detection efficiency of subsequent detection tasks.

[0111] In one embodiment, the detection method further comprises:

[0112] If the operating condition data does not meet the preset conditions, the result that the operating condition data does not meet the preset conditions is returned to the detection device, and the detection task corresponding to the detection request is refused to be executed.

[0113] In the embodiment of the present application, when the vehicle ECU determines that the mobile phone to working condition data does not meet the preset conditions, the system will generate an abnormality report and send this report back to the detection device. At the same time, the system will cancel or refuse to perform the task related to the detection request. For example, if the engine temperature exceeds the preset limit, the system may not allow emission detection until the temperature returns to normal.

[0114] In one embodiment, the present application discloses a detection system, including a detection terminal and at least one electronic control unit of a vehicle to be tested that executes any of the above detection methods.

[0115] In an embodiment of the present application, a detection system is provided, which is composed of a detection terminal and an electronic control unit (ECU) of a vehicle to be tested, and the ECU is capable of executing a specific detection method. The detection terminal refers to a special device or software interface for sending requests to the ECU and receiving data from the ECU, processing the data, and displaying the detection results. The detection terminal may be portable or fixedly installed on the vehicle. The ECU is one or more electronic modules on the vehicle, responsible for monitoring and controlling various systems of the vehicle, such as engine management, transmission system, braking system, etc. In the detection system, the ECU is responsible for executing the actual detection method, such as collecting data, performing diagnostic tests, etc.

[0116] See also Figure 5 , is a schematic diagram of the structure of the detection method provided in the embodiment of the present application, and the steps of performing detection using the above detection system are as follows:

[0117] 1) The detection device sends a detection request to the vehicle ECU;

[0118] 2) The vehicle ECU determines whether the detection request contains the first identifier, and if so, executes step 3), and if not, executes step 6);

[0119] 3) The vehicle ECU obtains the preset conditions;

[0120] 4) Vehicle ECU obtains working condition data;

[0121] 5) The vehicle ECU determines whether the operating condition data meets the preset conditions. If so, it executes step 6). If not, it directly returns to the testing equipment;

[0122] 6) Vehicle ECU performs detection tasks;

[0123] 7) Vehicle ECU obtains the test results;

[0124] 8) The vehicle ECU returns the test results to the testing equipment.

[0125] In the above method, the vehicle ECU stores the dependency conditions (preset conditions) sent by the detection device and integrates these multiple conditions to generate a dependency ID. When executing the detection task, if there are dependency conditions, the corresponding dependency ID and the detection task can be sent to the ECU together. The ECU will automatically determine whether each condition is met based on the dependency ID. If not, it returns that the condition is not met. If it is met, the detection task is directly executed and the result is returned. In this way, repeated instructions to judge dependencies can be reduced, which can improve detection efficiency.
