[0061] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] In an exemplary embodiment, Figure 1 As shown, a suspension K&C test simulation data processing method is provided. This embodiment uses the method applied to a computer device as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a computer device and a server, and is implemented through the interaction between the computer device and the server, which is not limited in this embodiment. The method includes:

[0063] Step 102, reading the simulation result file and the test result file through the human-computer interaction interface.

[0064] In an optional implementation, a computer device is connected to a K&C test bench, and the test under specific working conditions is completed through the K&C test bench. Simulation software and a setting program are run on the computer device, and simulation under specific working conditions is realized through the simulation software. The setting program run by the computer device provides a human-computer interaction interface. In response to the user's operation, the setting program of the computer reads the simulation result file output by the simulation software and the test result file output by the K&C test bench. It can be understood that each step of the method provided in the embodiment of the present application can be set as a Python class, which can be repeatedly called during the data processing process to make the program more streamlined.

[0065] The user selects the simulation result file and the test result file to be processed based on the GUI (Graphical User Interface) interface displayed on the computer device. The simulation result file can be a res format file generated by ADAMS / Car software simulation. The test result file can be a txt format file generated by the K&C test bench test.

[0066] Step 104 , extracting data of each parameter item from the simulation result file and the test result file respectively according to the K&C working condition, and obtaining simulation slice data and test slice data.

[0067] Optionally, the computer device pre-stores parameter item identifiers corresponding to each specific K&C working condition, and based on the parameter item identifiers, extracts specific data from the simulation result file and the test result file to obtain simulation slice data and test slice data consisting of data of multiple parameter items.

[0068] Optionally, by traversing the header data of the simulation result file, cache the identification id and unit required for calculating each working condition parameter item, and extract specific data through the retrieval id function. According to the parameter annotations in the declaration file supporting the K&C test bench, determine the identification id of each parameter item, and extract specific data through the retrieval id function.

[0069] Optionally, the K&C operating condition of this embodiment can be any specific operating condition, specifically at least one of a parallel wheel hop condition, a reverse wheel hop condition, an in-place turning condition, a same-direction lateral force condition, a reverse lateral force condition, a same-direction longitudinal force condition, a same-direction return torque condition, and a reverse return torque condition.

[0070] Step 106, converting the format of the simulation slice data to obtain simulation data.

[0071] Step 108 , converting the format of the test slice data according to the simulation coordinate system corresponding to the simulation slice data to obtain test data.

[0072] Among them, by converting the formats of simulation slice data and test slice data, the units, significant figures and coordinate systems of simulation data and test data are consistent. For example, the length units are converted to mm, the angle units are converted to deg, and the force units are converted to N. For another example, the data is rounded to three decimal places. For another example, the positive direction of X is uniformly defined as being opposite to the longitudinal movement direction of the car, and the positive directions of Y and Z form a right-handed coordinate system with the positive direction of X.

[0073] Step 110, calculating the values ​​of various parameter items of the K&C condition according to the simulation data and the test data.

[0074] The computer device calculates the value of each parameter item according to the calculation method of each parameter item, using the simulation data and the test data as references.

[0075] Among them, the parallel wheel hop condition requires the calculation of suspension stiffness, toe angle change, caster angle change, camber angle change, roll center height, wheel center longitudinal displacement change, and wheel center lateral displacement change. The reverse wheel hop condition requires the calculation of suspension roll stiffness with / without stabilizer bar, total roll stiffness, toe angle change, and camber angle change. The in-situ steering condition requires the calculation of steering gear ratio, kingpin inclination trail at ground contact point, kingpin caster offset at ground contact point, wheel center kingpin inclination trail, wheel center kingpin caster trail, kingpin inclination angle, kingpin caster angle, and 20° wheel angle Ackerman percentage. The same-direction lateral force condition requires the calculation of wheel center lateral flexibility, toe angle change, and caster angle change. The reverse lateral force condition requires the calculation of wheel center lateral flexibility, toe angle change, and caster angle change. The same-direction longitudinal force condition requires the calculation of wheel center longitudinal flexibility, toe angle change, and brake anti-nod. The toe stiffness needs to be calculated for the same direction return moment and the toe stiffness needs to be calculated for the reverse direction return moment.

[0076] It can be understood that the parameters used in the calculation in this embodiment can be directly read from the pre-processed data; optionally, the simulation data after format conversion is pre-stored in Data Frame1 (data structure), and the relevant data can be directly read from the Data Frame1 during calculation. Taking the parallel wheel jump toe angle change item as an example, the wheel center vertical displacement data column is extracted from Data Frame1 as the X-axis, and the toe angle data column is extracted as the Y-axis. The Y-axis is fitted with the first-order fitting of the X-axis ±10mm data segment to obtain the toe angle change gradient value, and the intersection of the fitting line and the Y-axis is taken as the toe angle value at the wheel jump 0 point.

[0077] Due to the limitation of sensor type during the test, some parameters need to be calculated in the middle. Taking the Ackerman percentage of the 20° wheel angle under the test in-situ steering condition as an example, the left wheel angle SaL, right wheel angle SaR, wheelbase WT, and wheelbase WB are taken from Data Frame2 (referring to the data structure in which the test data is stored in advance). Figure 2 , Figure 2 The Ackerman steering geometry is shown. The calculation process is as follows:

[0078]

[0079] Through the above formula, the data column of Ackerman rate and Ackerman error can be determined. The Ackerman percent value corresponding to the left wheel turning angle of 20° is the Ackerman percent of the 20° wheel turning angle in the on-the-spot steering condition.

[0080] In the above suspension K&C test simulation data processing method, the simulation result file and the test result file are read through the human-computer interaction interface; the data of each parameter item is extracted from the simulation result file and the test result file respectively according to the K&C working condition to obtain the simulation slice data and the test slice data; the simulation slice data is formatted to obtain the simulation data; according to the simulation coordinate system corresponding to the simulation slice data, the test slice data is formatted to obtain the test data; and the values ​​of each parameter item of the K&C working condition are calculated according to the simulation data and the test data. In the above manner, by reading files, extracting data, format conversion and parameter calculation, the K&C simulation and test data can be automatically processed, the processing operation is simplified, the processing efficiency is improved, and the vehicle development efficiency is improved.

[0081] In an exemplary embodiment, step 104 includes: determining the parameter item identifier corresponding to the K&C working condition; according to the parameter item identifier, traversing the simulation result file and the test result file respectively, extracting the data and units corresponding to the parameter item identifier, and obtaining the simulation slice data and the test slice data.

[0082] Among them, the parameter item identification can be determined by pre-stored data, and the parameter item identification of the simulation can also be determined by analyzing the simulation result file, and the parameter item identification of the test can be determined by analyzing the test result file. In an optional implementation method, based on the data structure of the simulation result file (res file), the res file header data is read, and the unit and id (parameter item identification) of each parameter are obtained by traversing the Pandas library (Python data analysis module). Through the retrieval id function, the specific data of each parameter item is obtained by using the Pandas library through the slicing command, and stored in the Data Frame (data structure). In an optional implementation method, according to the declaration file of the test bench, the specific data of each parameter item is extracted by the slicing command using the Pandas library and stored in the DataFrame.

[0083] Exemplarily, some pseudo codes for implementing the above-mentioned process of traversing the simulation result files are as follows:

[0084]

[0085]

[0086] In an exemplary embodiment, step 106 includes: performing unit conversion on the simulation slice data according to the set unit, and performing format conversion on the simulation slice data according to the set effective digits to obtain simulation data;

[0087] Step 108 includes: performing unit conversion on the test slice data according to the set unit; performing format conversion on the test slice data according to the set effective digits; performing coordinate system conversion on the test slice data according to the simulation coordinate system corresponding to the simulation slice data to obtain the test data.

[0088] Among them, the setting unit is the unit of each parameter item set in advance, and the setting of significant figures refers to the number of significant figures retained by the pre-agreed numerical value. Both the setting unit and the setting of significant figures can be adjusted according to actual needs. Convert the units of simulation slice data and test slice data to a unified setting unit. Exemplarily, the Pandas library is used to traverse the loop, and the unit of the data in the Data Frame is converted from rad to deg; the unit of the length data in the Data Frame is converted to mm; the unit of the force data in the DataFrame is converted to N. Exemplarily, the Pandas library is used to traverse the loop, and the data in the DataFrame is converted from str (string) format to float (floating point) format with three decimal places.

[0089] It is understandable that the data corresponding to each parameter item in the K&C working condition may be vector data, which is data with direction. It is necessary to unify the positive and negative directions of the vector data by unifying the vehicle coordinate system. For example, the Pandas library and the Numpy library are used to perform traversal loops to complete the conversion of the coordinate system of the data in the DataFrame.

[0090] Exemplarily, some pseudo codes for implementing the above unit conversion process are as follows:

[0091]

[0092]

[0093] Exemplarily, some pseudo codes for implementing the above-mentioned effective digit adjustment process are as follows:

[0094]

[0095] In an exemplary embodiment, step 110 includes: fitting and generating curves corresponding to each parameter item based on simulation data and test data; obtaining change information during the test process or simulation process based on the fitted curve; and calculating the values ​​of each parameter item of the K&C working condition based on the simulation data, test data and change information.

[0096] Among them, the Numpy library is used to perform linear fitting on the simulation data and the test data, generate the curves corresponding to each parameter item, and obtain the slope and hysteresis of the parameters in the test and simulation. Figure 3 Based on the simulation data and test data, linear fitting is performed to determine the test gradient (slope), test hysteresis, simulation gradient and other change information within the fitting interval. Based on the simulation data, test data and change information, the values ​​of each parameter item of the K&C condition are calculated according to the specific solution method of each parameter item.

[0097] Exemplarily, some pseudo codes for implementing the above linear fitting process are as follows:

[0098] slope1,intercept1=np.polyfit(x_down_up,y_down_up,1)

[0099] In an exemplary embodiment, Figure 4 As shown, the method provided by the present application also includes:

[0100] Step 402, generating a display screen according to the values ​​of each parameter item of the K&C working condition, and visually displaying the display screen.

[0101] Step 404: Generate trend comparison information based on the simulation data and the test data, and visualize the trend comparison information.

[0102] Among them, the embodiment of the present application also provides a visualization tool, which can visualize the values ​​of each parameter item of the K&C working condition, and can also visualize the comparison results of simulation data and test data. It mainly includes a calculation result summary page and a curve relationship display page. Optionally, the Pyecharts library is used to visualize the comparison data. The display content mainly includes: the change trend and slope of the K&C parameter items, comparison of test and simulation trends, etc.

[0103] Exemplarily, some pseudo codes for implementing the above process are as follows:

[0104]

[0105]

[0106] It can be understood that in the visualization method of this embodiment, the calculation results and the fitting relationship are visualized to facilitate the user to obtain trend information and comparison results.

[0107] Optionally, the visualization display page includes a calculation result summary page and a curve relationship display page. Figure 5 , Figure 5 A calculation result summary page is shown, which includes a table including specific data of suspension stiffness, toe angle change, caster angle change, camber angle change, wheel center longitudinal displacement change, wheel center lateral displacement change, and anti-nodding angle. The data columns of the table include: simulation value of the left wheel, test value of the left wheel, simulation value of the right wheel, and test value of the right wheel.

[0108] Reference Figure 6 , Figure 6 A curve relationship display page is shown. By interactively clicking on the tabs at the top of the page, you can jump to the corresponding indicator item. Each tab page can display at least one view. Figure 5 The views shown in the figure include: there is a corresponding data display or hiding switch at the top of the view to control the display or hiding of each curve; the specific data value of each point can be displayed by the cursor in the view.

[0109] In this embodiment, by visually displaying the values ​​and trend comparison information of each parameter item of the K&C working condition, the data can be made more intuitive and easy to understand, and potential features in the data can be more easily discovered, thereby improving processing efficiency.

[0110] In an exemplary embodiment, the K&C condition includes at least one of a parallel wheel hop condition, a reverse wheel hop condition, an in-place turning condition, a same-direction lateral force condition, a reverse lateral force condition, a same-direction longitudinal force condition, a same-direction return torque condition, and a reverse return torque condition.

[0111] Among them, the K&C simulation and test of this embodiment focus on 8 working conditions, namely: parallel wheel hop condition, reverse wheel hop condition, in-situ turning condition, same-direction lateral force condition, reverse lateral force condition, same-direction longitudinal force condition, same-direction return torque condition and reverse return torque condition.

[0112] In an exemplary embodiment, referring to Figure 7 The suspension K&C test simulation data processing method includes the following steps: extracting data and slicing cache for K&C simulation result files and K&C test result files respectively, and then preprocessing the data to unify the units, valid figures, and coordinate systems. Extracting parameters for each simulation condition, and extracting and calculating parameters for each test condition. Summarizing the calculation results, and comparing the curves of each parameter item. Visualizing the calculation results and fitting relationships.

[0113] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
