When the engine ECU is calibrated and matched based on the existing engine ECU data matching and calibrating method, the technical problems that the generated calibration report can not be stored and shared on line, the requirement on the technical level of an engineer is high and the like exist generally.
Aiming at the technical problems in the prior art, the embodiment of the application provides an engine ECU data matching calibration method, which can automatically determine a calibration result and reduce the requirements on the technical level of engineers.
The engine ECU data matching calibration method provided by the embodiment of the application is firstly introduced in entirety as follows:
the embodiment of the application provides an engine ECU data matching calibration method, which is applied to an online calibration system, wherein the online calibration system comprises an ECU calibration data storage database, a calibration rule calling module, a data analysis module and an ECU calibration data calibration module; the online calibration system monitors whether a newly added data record exists in an ECU calibration data storage database; when it is monitored that a newly added data record exists in the ECU calibration data storage database, extracting the newly added data record from the ECU calibration data storage database as a verified object; then, a verification rule data calling module is called, and a verification rule is correspondingly called from a verification rule storage database according to the verified object to form a verification rule set of the verification; the verification storage database is used for storing verification rules related to engine performance and emission specifications; then, calling a data analysis module to analyze the checked object, and determining variable information and a calibration value corresponding to the checked object; and then, calling an ECU calibration data calibration module, and determining a calibration result according to the variable information and the calibration value corresponding to the calibrated object by using the calibrated rule set.
The engine ECU data matching calibration method is based on the ECU calibration data storage database, monitors the dynamic state of the ECU calibration data in real time, and realizes the automatic and batch calibration of the calibration data; the method comprises the steps of determining a calibration rule set corresponding to newly added data records in an ECU calibration data storage database based on a calibration rule storage database, and then calibrating the newly added data records based on the calibration rule set.
The engine ECU data matching calibration method provided by the application is described in an embodiment mode as follows:
referring to fig. 2, fig. 2 is a schematic flow chart of an engine ECU data matching calibration method provided by the embodiment of the present application. The engine ECU data matching calibration method is applied to an online calibration system, and the online calibration system comprises an ECU calibration data storage database, a calibration rule calling module, a data analysis module and an ECU calibration data calibration module. As shown in FIG. 1, the engine ECU data matching calibration method comprises the following steps:
step 201: and monitoring whether a newly added data record exists in the ECU calibration data storage database.
The online calibration system monitors whether a newly added data record exists in the ECU calibration data storage database in real time, wherein the newly added data record is usually generated by adjusting the ECU initial calibration data in the running process of the engine, namely once the ECU initial calibration data is adjusted, the ECU calibration data storage database is correspondingly added with the newly added data record which corresponds to the adjustment of the ECU initial calibration data.
Before matching and calibrating the engine ECU, the online calibration system usually reads the initial parameters of the ECU from the ECU to be matched and calibrated to serve as initial calibration data of the ECU, and further stores the initial calibration data of the ECU in an ECU calibration data storage database, and subsequently matches and calibrates the engine ECU based on the initial calibration data of the ECU.
Step 202: and when the ECU calibration data storage database has a newly added data record, extracting the newly added data record from the ECU calibration data storage database as a verified object.
When the online system detects that a newly added data record exists in the ECU calibration data storage database, the initial parameters of the ECU of the engine are adjusted in the running process of the engine, and then the newly added data record is extracted from the ECU calibration data storage database and is used as a checked object, so that whether the adjustment on the ECU calibration data at this time meets a check rule or not is determined, and whether the adjustment on the ECU calibration data at this time is reasonable or not is determined.
It should be noted that the checked object usually includes new data and characteristic attributes corresponding to the new data, where the new data refers to the adjusted ECU parameter, and the characteristic attribute corresponding to the new data refers to a data category to which the new data belongs, and specifically may be a rotation speed, power consumption, and the like.
It should be understood that, in most cases, during the process of performing matching calibration on the engine ECU, a large number of parameters in the ECU need to be adjusted accordingly, so that, in general, a large number of new data may be included in the new data record, and the feature attributes corresponding to each new data may be included in each new data record.
Step 203: and calling the verification rule calling module, and correspondingly calling the verification rules from the verification rule storage database according to the verified object to form a verification rule set of the verification.
After the online calibration system monitors that newly added data records exist in the ECU calibration data storage database, the online calibration system correspondingly calls the calibration rule calling module of the online calibration system, so that the calibration rule calling module is utilized to correspondingly call the calibration rule from the calibration rule storage database according to the object to be calibrated, and further, the calibration rule called from the calibration rule storage database is utilized to form a calibration rule set of the calibration.
It should be noted that the check rule storage database is used for storing the check rules related to the engine performance and the emission specifications, wherein the stored check rules are rules summarized and formed by deep analysis and mining of the development experience of the ECU calibration data and the market fault solving measures by professional engineers, and have high reliability.
It should be noted that each of the check rules stored in the check rule storage database corresponds to a different single variable, that is, the check rule storage database stores the check rule using the variable as a unit, and the different check rules correspond to different variables. The specific check rule stored in the check rule database is shown in fig. 3, where the variable type and the check rule type form a corresponding constraint logic.
Specifically, when the verification rule is called, the online calibration system calls a verification rule calling module to match the characteristic attributes corresponding to the newly-added data in the verified object with the characteristic attributes corresponding to the verification rules stored in the verification rule storage database, and then calls the verification rules with successfully matched characteristic attributes to form a verification rule set for the verification.
Specifically, the new data and the characteristic attributes corresponding to the new data are included in the checked object, so that when the online calibration system calls the check rules, the characteristic attributes corresponding to the new data can be matched with the characteristic attributes corresponding to the check rules in the check rule storage database, if the matching is successful, the check rules are the check rules for checking the new data, the check rules are correspondingly extracted, the check rules corresponding to the new data are determined, and the check rules form the check rule set of this time.
Step 204: and calling the data analysis module to analyze the checked object, and determining variable information and a calibration value corresponding to the checked object.
After the on-line calibration system determines the checked object, a data analysis module can be called to analyze the checked object, so that variable information and a calibration value corresponding to the checked object are determined.
Specifically, the data analysis module may analyze each newly added data in the checked object, so as to determine variable information corresponding to each newly added data, where the variable information is generated by adjusting engine ECU parameters in a development process, and a calibration value corresponding to each newly added data, and the calibration value is an ECU initial calibration parameter corresponding to the newly added data.
It should be noted that, in practical applications, step 203 may be executed first and then step 204 is executed, step 204 may be executed first and then step 203 is executed, and step 203 and step 204 may also be executed simultaneously, where the execution sequence of step 203 and step 204 is not limited at all.
Step 205: and calling the ECU calibration data calibration module, and determining a calibration result according to the variable information and the calibration value corresponding to the calibration object by using the calibrated rule set.
After determining the check rule set of the current check and analyzing to obtain the variable information and the calibration value of the checked object, the online calibration system further calls an ECU calibration data check module, which may determine the check result corresponding to each newly added data record according to the variable information and the calibration value of the checked object obtained in step 204 by using the check rule set determined in step 203, that is, determine whether each newly added data record satisfies the corresponding check rule.
It should be noted that the checked object usually includes a large number of newly added data records, and in order to improve the checking efficiency, the online calibration system may perform batch checking processing by using multiple threads.
Specifically, the online calibration system calls an ECU calibration data check module to divide variable information and calibration values corresponding to each newly added data record into a plurality of processing queues, each processing queue corresponds to one processing thread, and then, in each processing thread, each newly added data record is checked by using an algorithm corresponding to each check rule, so as to determine a check result corresponding to each newly added data record.
In addition, the online calibration system provided in the embodiment of the present application may further include a verification result display module, and accordingly, after the verification result corresponding to the verified object is determined, the online calibration system may further invoke the verification result display module to display the variable information, the calibration value, the verification rule, and the verification result corresponding to the verified object.
Namely, the online calibration system displays the variable information, the calibration value, the calibration rule and the calibration result corresponding to each newly added data record in the object to be calibrated by using the calibration result display module, so that relevant workers can conveniently summarize and evaluate the data matching calibration process of the engine ECU according to the display content.
In addition, the online calibration system provided in the embodiment of the present application may further include a verification report generation module, and accordingly, after the online calibration system determines the verification result corresponding to the verified object, the online calibration system may call the verification report generation module, generate a verification report according to the determined verification result, export the verification report to the ECU calibration data storage database, and store the verification report of this verification in the ECU calibration data storage database.
The online calibration system provided by the embodiment of the application supports online storage and sharing, so that relevant workers can call the calibration reports stored in the ECU calibration data storage database at any time, correspondingly research and analyze the calibration reports according to the calibration reports of each calibration, and provide data for reference in other engine ECU data matching calibration processes.
