Description

Technical Field

[0001] This application relates to the field of simulation testing technologies, and particularly to a method, apparatus, device, and storage medium for logically displaying program variables. Background Art

[0002] The measurement of an Electronic Control Unit (ECU) program usually uses specialized measurement tools. For example, CANape or INCA commonly used in this industry.

[0003] In the prior art, CANape or INCA can measure the running values of variables in the ECU program in real time to monitor the running conditions of the variables in the ECU program. However, when CANape or INCA detects an abnormal situation, it can only display one or more variables and running values associated with the abnormal situation in its monitoring interface, and cannot display the control strategies associated with the above one or more variables. Since the purpose of developers or testers to measure ECU program variables is to find out whether there are control abnormal situations in the ECU program, and when a control abnormal situation is detected, based on the control strategies associated with the control abnormal situation, the existing ECU program is adjusted to obtain an ECU program with the control effect meeting the expectations.

[0004] Then, in the prior art, when using the above CANape or INCA to measure ECU program variables and an abnormal situation is detected, developers or testers still need to consult the associated control strategies based on the above one or more variables for offline analysis, which not only makes the testing process less intuitive but also increases the workload of troubleshooting abnormal situations. Summary of the Invention

[0005] Embodiments of this application provide a method, apparatus, device, and storage medium for logically displaying program variables to make the ECU program testing process more intuitive and improve the troubleshooting efficiency of abnormal situations.

[0006] The specific technical solutions provided by the embodiments of this application are as follows:

[0007] In a first aspect, embodiments of this application provide a method for logically displaying ECU program variables, including:

[0008] Generating a to-be-tested ECU program based on an ECU control logic simulation model built in a simulation software interface, where the ECU control logic simulation model is composed of at least two graphic modules connected according to a control logic;

[0009] Determine the set of variables to be displayed for the ECU program to be tested based on the variable description file of the ECU program to be tested and the ECU control logic simulation model, where the variable description file includes the description information of each variable included in the ECU program to be tested;

[0010] Based on the set of variables to be displayed, within the preset range corresponding to the graphic module included in the ECU control logic simulation model, set the running value display boxes corresponding to the variables to be displayed;

[0011] In response to the start test instruction, continuously collect the running values of each variable included in the set of variables to be displayed, and display the running values in the running value display boxes corresponding to the variables to be displayed.

[0012] In the above method, by setting the running value display boxes for each variable included in the set of variables to be displayed, the running values of each variable obtained by the ECU controller when running the ECU program to be tested can be intuitively and dynamically displayed in the ECU control logic simulation model, so that developers or testers can more intuitively view the test process through the ECU control logic simulation model as the client interface, and when it is monitored that the running value of a certain variable or certain variables is abnormal, the corresponding control logic can be intuitively viewed in the ECU control logic simulation model to quickly find out the cause of the abnormal problem, improve the troubleshooting efficiency, and thus improve the test efficiency.

[0013] Optionally, the determining the set of variables to be displayed for the ECU program to be tested based on the variable description file of the ECU program to be tested and the ECU control logic simulation model includes:

[0015] Obtain each variable from the ECU control logic simulation model, and form the second variable set with the each variable;

[0016] Determine the intersection of the first variable set and the second variable set, and use the intersection as the set of variables to be displayed.

[0017] In the above method, since the ECU control logic simulation model is drawn according to the control logic, through the above screening operation, the set of variables to be displayed can be accurately determined, so as to accurately display the running values of the variables to be displayed in the ECU control logic simulation model, and then accurately and intuitively reflect the test process, so that developers or testers can accurately make judgments on the ECU program to be tested, improving the test efficiency.

[0018] Optionally, within a preset range corresponding to the graphic module included in the ECU control logic simulation model based on the set of variables to be displayed, set a running value display box for the variables to be displayed, including:

[0020] Use the area where the variable value label is located as the running value display box for the corresponding variable to be displayed.

[0021] The above method can use the default label in the Simulink simulation software - the Simulink.Annotation label to add a running value display box for each variable to be displayed, so as to intuitively and dynamically display the running values of each variable to be displayed in the ECU control logic simulation model, thereby improving the test efficiency.

[0025] Continuously communicate with the ECU controller through the CAN adapter and communication protocol to obtain the running values of each variable to be displayed included in the set of variables to be displayed.

[0026] The above method, through the CAN adapter and communication protocol, can real-time the running values of each variable obtained by the ECU controller running the ECU program to be tested, so as to facilitate directly and dynamically displaying the obtained running values in the ECU control logic simulation model subsequently, making the test process more intuitive and the troubleshooting of abnormal situations more convenient.

[0027] Optionally, the method further includes:

[0028] If there are already displayed running values in the running value display box, after obtaining the new running value of the corresponding variable to be displayed, update the already displayed running value based on the new running value.

[0029] The above method can intuitively and dynamically display the running values of each variable obtained by the ECU controller running the ECU program to be tested in the ECU control logic simulation model in real time. In this way, the testing process becomes more intuitive, facilitating the improvement of testing efficiency.

[0060] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0061] It should be noted that the terms "first", "second", "third", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here.

[0062] In order to solve the problems that the testing process in the prior art is not intuitive enough and the troubleshooting efficiency for abnormal situations is low, in the embodiments of the present application, based on the variable description file of the ECU program to be tested and the ECU control logic simulation model, a set of variables to be displayed for the ECU program to be tested is determined. Among them, the ECU program to be tested is generated based on the ECU control logic simulation model built in the simulation software interface. The ECU control logic simulation model is composed of at least two graphic modules connected according to the control logic. The variable description file includes the description information of each variable included in the ECU program to be tested; then, based on the set of variables to be displayed, within the preset range corresponding to the graphic modules included in the ECU control logic simulation model, value display frames corresponding to the variables to be displayed are set; then, in response to the start testing instruction, the running values of each variable to be displayed included in the set of variables to be displayed are continuously collected, and the running values are displayed in the value display frames corresponding to the variables to be displayed; in this way, the real-time running values of the variables in the ECU program are dynamically displayed in the ECU control logic simulation model, making the testing process more intuitive. Thus, when it is determined that the running value of a certain variable or certain variables is abnormal, the control logic between the above-mentioned certain variable or certain variables can be intuitively viewed, thereby improving the troubleshooting efficiency for abnormal situations.

[0063] Refer to Figure 1 As shown, it is a schematic diagram of the application scenario in the embodiments of the present application. The schematic diagram of the application scenario includes an ECU controller, a CAN adapter, and a terminal device; among them,

[0064] The ECU controller is the object to be tested and is used to run the ECU program to be tested;

[0065] The CAN adapter is an interface converter and is used for communication between the ECU controller and the terminal device;

[0066] The terminal device is used to store the ECU control logic simulation model matching the program to be tested, communicate with the ECU controller through the CAN adapter, and display the real-time running value in the ECU controller in the ECU control logic simulation model in real time.

[0067] In the embodiments of the present application, the above-mentioned CAN adapter can be a third-party adapter such as ES581 or CANapeXL; the above-mentioned ECU control logic simulation model can be a simulink model built in the Simulink simulation software interface.

[0068] It should be noted that the Simulink simulation software is a visual simulation tool in MATLAB. It is a block diagram design environment based on MATLAB and is a software package for realizing dynamic system modeling, simulation, and comprehensive analysis. It is widely used in the modeling and simulation of linear systems, non-linear systems, digital control, and digital signal processing. In this Simulink environment, there is no need to write a large number of programs, and complex systems can be constructed only through simple and intuitive mouse operations.

[0069] The following further elaborates on the preferred embodiments of the present application in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application. And without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0070] Refer to Figure 2 As shown, a method for logically displaying ECU program variables provided by an embodiment of the present application has the following specific process:

[0071] Step 200: Generate a to-be-tested ECU program based on an ECU control logic simulation model built in the simulation software interface. The ECU control logic simulation model is composed of at least two graphic modules connected according to the control logic.

[0072] In an embodiment of the present application, a developer or tester builds an ECU control logic simulation model in the simulation software interface. Then, the terminal device generates a corresponding to-be-tested ECU program based on the ECU control logic simulation model built by the developer or tester in the simulation software interface.

[0073] In an embodiment of the present application, after step 200 is executed, the terminal device inputs the to-be-tested ECU program into the ECU controller so that the ECU controller runs the to-be-tested ECU program to obtain the running values of each variable included in the to-be-tested ECU program.

[0074] In an embodiment of the present application, a developer or tester can obtain the above-mentioned ECU control logic simulation model in the following manner: First, based on the control logic, select the required corresponding graphic modules from the module library of the Simulink simulation software, and complete the modeling based on the selected graphic modules, thereby obtaining the above-mentioned ECU control logic simulation model.

[0075] Optionally, in an embodiment of the present application, the terminal device can also build the above-mentioned ECU control logic simulation model based on a script file written by a developer or tester. The specific manner of specifically building the ECU control logic simulation model is not limited.

[0076] Step 210: Based on the variable description file of the ECU program to be tested and the ECU control logic simulation model, determine the set of variables to be displayed in the ECU program to be tested. This variable description file includes the description information of each variable included in the ECU program to be tested.

[0077] In the embodiments of the present application, when performing Step 210, specifically, by performing the following operations, determine the set of variables to be displayed in the ECU program to be tested:

[0078] Operation 1: Read each variable from the variable description file of the ECU program to be tested, and form the first variable set with each variable.

[0079] Under the prior art, the simulink simulation software can generate a corresponding code program based on the simulink model in the simulation software interface. At the same time, in actual applications, when generating the code program, a variable description file matching the generated code program can be generated, for example, an A2L file.

[0080] Then, in the embodiments of the present application, when performing Operation 1, read each variable from the variable description file matching the ECU program to be tested, and form the first variable set with each read variable.

[0081] Operation 2: Obtain each variable from the ECU control logic simulation model, and form the second variable set with each variable.

[0082] In the embodiments of the present application, when performing Operation 2, obtain each variable from the ECU control logic simulation model, and then form the second variable set with each obtained variable.

[0083] Operation 3: Determine the intersection of the first variable set and the second variable set, and use the intersection as the set of variables to be displayed.

[0084] In the embodiments of the present application, when performing Operation 3, compare the first variable set and the second variable set obtained by performing Operation 1 and Operation 2 respectively, so as to determine the intersection of the above first variable set and the second variable set, and use this intersection as the set of variables to be displayed. In this way, it can be ensured that each displayed variable is included in both the ECU control logic simulation model and the ECU program to be tested, thereby ensuring the accuracy and effectiveness of the running values of the variables displayed during subsequent testing.

[0085] It should be noted that in the embodiments of the present application, the above variables refer to physical quantities that are dynamically changing and can be measured.

[0086] Step 220: Based on the set of variables to be displayed, within the preset range corresponding to the graphic module included in the ECU control logic simulation model, set the running value display box for the corresponding variables to be displayed.

[0087] In the embodiment of the present application, by executing Step 220, a running display box is set for each variable to be displayed included in the set of variables to be displayed determined in Step 210, so that the running values of each variable to be displayed obtained subsequently can be displayed near the corresponding variable to be displayed, making the testing process more intuitive.

[0088] In practical applications, in the ECU control logic simulation model, variable value labels can be set for each variable to be displayed included in the set of variables to be displayed, where the variable value labels corresponding to different variables to be displayed are different; then, the area where the variable value labels are located is used as the running value display box for the corresponding variables to be displayed.

[0089] In the embodiment of the present application, the above-mentioned running value display box can be implemented by adding tags such as Simulink.Annotation in Simulink for each variable to be displayed included in the set of variables to be displayed, or can be obtained by adding annotations in any form for each variable to be displayed; the specific form of the above-mentioned running value display box is not limited to the above form, and no specific limitation is made here.

[0090] Step 230: In response to the start test instruction, continuously collect the running values of each variable to be displayed included in the set of variables to be displayed, and display the running values in the running value display box corresponding to the variable to be displayed.

[0091] In the embodiment of the present application, after executing Step 220, the ECU program to be tested can be started for testing. Specifically, when executing Step 230, in response to the start test instruction, automatically retrieve each variable to be displayed for which the running value display box has been set, continuously communicate with the ECU controller through the CAN adapter and communication protocol, and obtain the running values of each variable to be displayed included in the set of variables to be displayed; then, display each obtained running value in the running value display box corresponding to the variable to be displayed.

[0092] Optionally, in the embodiment of the present application, when executing Step 230, if there is a displayed running value in the running value display box, after obtaining the new running value of the corresponding variable to be displayed, update the displayed running value based on the new running value. In this way, the real-time running values of each variable to be displayed obtained by the ECU controller running the ECU program to be tested can be timely displayed in the ECU control logic simulation model, thereby making the testing process more intuitive, facilitating the troubleshooting of abnormal situations, and further improving the testing efficiency.

[0093] It should be noted that in the embodiments of the present application, before testing, the terminal device needs to perform a communication handshake negotiation with the ECU controller to determine the communication protocol between the terminal device and the ECU controller. Then, when step 230 is executed, through the CAN adapter and the pre-determined communication protocol, smooth communication between the terminal device and the ECU controller can be achieved.

[0094] In the embodiments of the present application, when step 230 is executed, it is determined whether a stop test instruction is received. If so, the test is stopped; otherwise, the running values of each variable to be displayed included in the variable set to be displayed are continuously collected, and the running values are displayed in the running value display box corresponding to the variable to be displayed.

[0095] For example, refer to Figure 3 As shown, take the testing of the ECU program to be tested between the terminal device and the ECU controller as an example.

[0096] Suppose a developer or tester builds an ECU control logic simulation model in the simulink simulation software of the terminal device.

[0097] Then, based on this ECU control logic simulation model, the terminal device generates the ECU program to be tested.

[0098] Then, in the ECU control logic simulation model, the terminal device sets the running value display box for each variable to be displayed included in the variable set to be displayed.

[0099] In specific implementation, refer to Figure 4 As shown, the terminal device realizes the functions of determining the variable set to be displayed and setting the running value display box for each variable to be displayed included in the variable set to be displayed in the ECU control logic simulation model by executing the following steps:

[0100] Step 400: Read each variable from the variable description file of the ECU program to be tested, and form the first variable set with each variable.

[0101] Step 410: Obtain each variable from the ECU control logic simulation model, and form the second variable set with each variable.

[0102] Step 420: Determine the intersection of the first variable set and the second variable set, and use the intersection as the variable set to be displayed.

[0103] Step 430: Based on the variable set to be displayed, set the running value display box for the corresponding variable to be displayed within the preset range corresponding to the graphic module included in the ECU control logic simulation model.

[0104] In the embodiment of the present application, after obtaining the set of variables to be displayed in step 420, when performing step 430, the function of adding labels in the Simulink simulation software can be used to add running value display boxes for each variable to be displayed.

[0105] Assume that the running value display box added for each display variable is a "Simulink.Annotation" label. Then, the area where the "Simulink.Annotation" label of each variable to be displayed is located is used as the running value display box corresponding to the variable to be displayed.

[0106] Also assume that the developer or tester clicks the start test button in the control interface of the terminal device.

[0107] Then, in the embodiment of the present application, referring to Figure 5 as shown, the terminal device realizes the data acquisition and display functions by executing the following steps:

[0108] Step 500: Respond to the start test instruction and retrieve the "Simulink.Annotation" label of each variable to be displayed included in the set of variables to be displayed.

[0109] Step 510: Continuously collect the running values of each variable to be displayed included in the set of variables to be displayed through the CAN adapter and the communication protocol.

[0110] Step 520: Display the running value in the "Simulink.Annotation" label corresponding to the variable to be displayed.

[0111] In the embodiment of the present application, when performing step 520, if there is a displayed running value in the running value display box, after obtaining the new running value of the corresponding variable to be displayed in step 510, update the displayed running value based on the new running value.

[0112] Step 530: Determine whether a stop test instruction is received. If so, execute step 540; otherwise, execute step 510.

[0113] Step 540: Respond to the stop test instruction and end the process.

[0114] In this way, the running values of each variable obtained by the ECU controller running the ECU program to be tested can be directly and dynamically displayed in the ECU control logic simulation model in real time. When it is detected that the running value of a certain variable or some variables is abnormal, the corresponding control logic can be intuitively viewed in the ECU control logic simulation model, and the cause of the abnormal problem can be quickly identified, thereby improving the troubleshooting efficiency and further improving the test efficiency.
