Fig. 2 is a schematic flow chart of a diagnostic parameter data verification method in an embodiment of the present application, and specifically includes the following steps:
in step 201, a vehicle diagnosis device acquires diagnosis parameter data generated by a vehicle terminal.
The vehicle terminal may be an Electronic Control Unit (ECU) for monitoring a vehicle state and controlling vehicle operation, and may generate diagnostic parameter data for vehicle diagnosis, which may reflect physical quantities and chemical quantities of a vehicle, an assembly, and a mechanism, including working process parameters (engine power, oil consumption, vehicle braking distance), working process accompanying parameters (vibration, noise, etc.), geometric parameters (clearance, free stroke), and the like.
Optionally, the vehicle diagnostic device may directly read the diagnostic parameter data generated by the vehicle terminal through a wired connection, or obtain the diagnostic parameter data generated by the vehicle terminal in a network communication manner through a wireless connection, and the vehicle terminal generates the diagnostic parameter data according to the first data generation rule.
By acquiring the diagnosis parameter data generated by the vehicle terminal, whether the format of the diagnosis parameter data provided by the vehicle terminal is wrong can be judged before formal diagnosis is carried out, so that the waste of manpower caused by using wrong diagnosis parameters to diagnose the vehicle is avoided.
the pre-negotiated first data generation rule may be a Diagnostic agreement agreed between a vehicle Diagnostic device manufacturer and a vehicle terminal manufacturer, and the Diagnostic agreement may be achieved based on a Universal Diagnostic Service (UDS).
Specifically, the first data generation rule may adopt two aspects to specify the target data.
In a first aspect, the format of diagnostic parameter data is normalized;
optionally, the format of the diagnostic parameter data may adopt an XML (extensible markup language) format, and the XML file has a smaller volume. The vehicle diagnosis equipment does not need to be internally provided with converters with various file formats, can directly read the acquired diagnosis parameter data in the XML format, and greatly improves the verification efficiency of the diagnosis parameter data;
in the second aspect, the content arrangement mode of the diagnosis parameter data is standardized;
for example, the object-oriented programming idea is adopted, the diagnosis parameters are divided into various classes according to functions, each class can be nested to contain other classes, the shared data is placed in the base class, and the other classes can be inherited from the base class. The names of all classes, class members and attributes of the classes are fixed in a rule file, and the diagnosis parameter data must generate a target data file with a specified format according to the rule.
The vehicle diagnostic equipment is internally provided with the first data generation rule, and can check whether the diagnostic parameter data of the vehicle terminal accords with the first data generation rule after being read, specifically, the first data generation rule and the diagnostic parameter data are loaded in sequence, and the correctness of the data file is checked by judging the number of classes, the members of the classes, the attributes and the related names in the diagnostic parameter data file.
If the diagnostic parameter data conforms to the first data generation rule, step 203 is executed.
And step 203, the vehicle diagnosis equipment performs diagnosis operation on the vehicle terminal according to the diagnosis parameter data.
The diagnosis operation is that the vehicle diagnosis equipment diagnoses the vehicle after determining that the diagnosis parameter data has no formal errors, and can comprise reading fault codes, clearing fault codes, reading data streams, reading freeze frames, performing action tests and other diagnosis functions.
Whether the diagnosis parameter data accord with the first data generation rule or not is verified according to the first data generation rule negotiated with the vehicle terminal in advance, whether the format of the diagnosis parameter data accords with the rule requirement or not can be judged before the vehicle is formally diagnosed, waste of manpower and material resources caused by repeated vehicle testing is avoided, the probability of errors when the vehicle diagnosis equipment reads the diagnosis parameter data generated by the vehicle terminal is reduced, and the efficiency of the vehicle diagnosis equipment for vehicle diagnosis is improved.
Next, a detailed description is given to a flow of another diagnostic parameter data verification method according to an embodiment of the present application with reference to fig. 3, where fig. 3 is a schematic flow diagram of another diagnostic parameter data verification method according to an embodiment of the present application, and specifically includes the following steps:
in step 301, a vehicle diagnostic device obtains diagnostic parameter data generated by a vehicle terminal.
if the diagnostic parameter data conforms to the first data generation rule, step 303 is executed.
If the diagnostic parameter data does not meet the first data generation rule, go to step 304.
And step 304, the vehicle diagnosis equipment sends feedback information to the vehicle terminal.
The feedback information is used for marking data which does not accord with the first data generation rule in the diagnosis parameter data, when the diagnosis parameter data is found not to accord with the first data generation rule completely, wrong data is accurately positioned through the rule to be marked, the vehicle diagnosis equipment packs the wrong data to generate the feedback information, and the feedback information is sent to the vehicle terminal so that the vehicle terminal can correct and supplement the wrong data.
By sending the feedback information to the vehicle terminal, the vehicle terminal can know which part of the diagnostic parameter data has the form error, and the vehicle diagnostic equipment can receive more accurate diagnostic parameter data.
In step 305, the vehicle diagnosis device acquires supplementary diagnosis parameter data generated by the vehicle terminal based on the feedback information.
The vehicle terminal generates supplementary diagnostic parameter data after receiving the feedback information and correcting the feedback information, the supplementary diagnostic parameter data are only wrong diagnostic parameter data but not all diagnostic parameter data, and the efficiency of correcting the diagnostic parameter data can be improved by targeted correction.
The vehicle diagnostic apparatus checks the supplementary diagnostic parameter data again, and the specific method may refer to the method described in step 302, which is not described herein again.
If the supplementary diagnostic parameter data meets the first data generation rule, step 307 is executed. If the supplemental diagnostic parameter data does not meet the first data generation rule, step 308 is executed.
And 307, the vehicle diagnosis equipment merges the supplementary diagnosis parameter data and the data which accords with the first data generation rule in the diagnosis parameter data, and executes diagnosis operation on the vehicle terminal according to the merged diagnosis parameter data.
By combining the supplementary diagnostic parameter data and the previous correct data, the diagnostic parameter data which accords with the first data generation rule can be obtained, partial data which accords with the rule can not be checked again, the error probability of the vehicle diagnostic equipment when reading the diagnostic parameter data generated by the vehicle terminal is reduced, and the efficiency of the vehicle diagnostic equipment for diagnosing the vehicle is improved.
The indication information is used for indicating the vehicle terminal to send a notification message of data error to a provider server corresponding to the vehicle terminal.
Specifically, when the vehicle terminal cannot correct the diagnosis parameter data, the vehicle diagnosis device can directly inform a manufacturer of the vehicle terminal of fault detection of the vehicle terminal, and the vehicle terminal is informed of possible faults by sending the indication information to the vehicle terminal, and then the vehicle terminal requests the corresponding supplier server for checking to prevent the vehicle terminal from entering the dead end where the diagnosis parameter data cannot be corrected, so that the waste of manpower and material resources caused by repeated vehicle testing is avoided.
Through the steps, data circulation can be kept in the same rule and format, and the diagnostic parameter data provided by a manufacturer can be quickly checked through the rule, so that errors can be found in advance and accurate positioning can be realized. The vehicle diagnosis method and the vehicle diagnosis device avoid repeated vehicle testing, waste of manpower and material resources is avoided, the probability of errors when the vehicle diagnosis device reads diagnosis parameter data generated by the vehicle terminal is reduced, and the efficiency of the vehicle diagnosis device in vehicle diagnosis is improved.

in step 401, a vehicle diagnostic device obtains diagnostic parameter data generated by a vehicle terminal.

If the diagnostic parameter data does not comply with the first data generation rule, go to step 404.
And step 403, the vehicle diagnosis equipment performs diagnosis operation on the vehicle terminal according to the diagnosis parameter data.
In step 404, the vehicle diagnosis device judges whether the vehicle diagnosis device has the diagnosis parameter data modification authority of the vehicle terminal.
The vehicle diagnosis equipment judges whether the vehicle terminal is authorized or not through self-checking and whether the acquired diagnosis parameter data can be modified or not. The vehicle terminal may enable the vehicle diagnostic device to directly modify the acquired diagnostic parameter data by issuing the token, or may directly send the unencrypted diagnostic parameter data, which is not specifically limited herein.
If the vehicle diagnosis device has the diagnosis parameter data modification authority of the vehicle terminal, step 405 is executed.
If the vehicle diagnosis device does not have the diagnosis parameter data modification authority of the vehicle terminal, step 406 is executed.
Whether feedback information needs to be sent to the vehicle terminal can be determined by confirming whether the vehicle diagnosis equipment has the modification authority or not, and the efficiency of checking the diagnosis parameter data can be improved.
In step 405, the vehicle diagnostic device verifies whether the diagnostic parameter data complies with a second data generation rule other than the first data generation rule.
The vehicle diagnosis device and the vehicle terminal only share one set of first data generation rule, but the vehicle diagnosis device can have a plurality of sets of second data generation rules and can diagnose various vehicle types, when the diagnosis parameter data sent by the vehicle terminal does not accord with the first data generation rule, the vehicle diagnosis device needs to check whether the diagnosis parameter data accords with the second data generation rule, if so, the step 410 is executed, and if not, the step 406 is executed.
And 406, the vehicle diagnosis device sends feedback information to the vehicle terminal.
And step 407, the vehicle diagnosis device acquires supplementary diagnosis parameter data generated by the vehicle terminal based on the feedback information.
The vehicle diagnosis equipment directly corrects the diagnosis parameter data, so that the steps of sending feedback information to the vehicle terminal and waiting for receiving supplementary diagnosis parameter data of the vehicle terminal can be omitted, and the efficiency of checking the diagnosis parameter data is improved.
And 411, the vehicle diagnosis equipment executes diagnosis operation on the vehicle terminal according to the corrected diagnosis parameter data.
The steps that are not described in detail above refer to the corresponding steps that are described in detail in fig. 2 and fig. 3, and are not described again here.
