[0091] Figure 4 An internal structural diagram of a computer device provided in an embodiment of the present invention. Detailed Implementation

[0092] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0093] The vehicle data management method provided in this application can be applied to, for example... Figure 1 In the application environment shown, vehicle 102 communicates with server 104 via a network. Vehicle 102 forwards vehicle component performance data and vehicle fault frequency to server 104. Server 104 first obtains the data types of the vehicle component performance data and vehicle fault frequency, where the data type of the vehicle component performance data is a vehicle component performance data type, and the data type of the vehicle fault frequency is a vehicle fault frequency type. Next, it determines whether both the vehicle component performance data type and the vehicle fault frequency type are quantitative. In response to determining that both the vehicle component performance data type and the vehicle fault frequency type are quantitative, server 104 performs a normality test on the vehicle component performance data and vehicle fault frequency, obtaining a normality test result. Based on the normality test result, a first correlation analysis algorithm is determined for performing correlation analysis on the vehicle component performance data and vehicle fault frequency. Alternatively, in response to determining that at least one of the vehicle component performance data type and vehicle fault frequency type is not quantitative, server 104 determines a second correlation analysis algorithm for performing correlation analysis on the vehicle component performance data and vehicle fault frequency. The correlation between the vehicle component performance data and vehicle fault frequency is obtained according to either the first or second correlation analysis algorithm. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0094] In one embodiment, such as Figure 2 As shown, a vehicle data management method is provided, which is applied to... Figure 1 Taking the server in the example, the following steps are included:

[0095] Step S101: Obtain the data types of vehicle component performance data and vehicle fault frequency, wherein the data type of vehicle component performance data is vehicle component performance data type, and the data type of vehicle fault frequency is vehicle fault frequency type.

[0096] Vehicle component performance data and vehicle failure frequencies can be acquired from multiple sources, including sensor data, inspection reports, and user feedback, and then pre-stored in a database. The database contains performance indicators and historical failure frequencies of components such as the engine and braking system, including data such as engine oil temperature and fuel consumption.

[0097] In some embodiments, the step of acquiring data types of vehicle component performance data and vehicle failure frequency includes:

[0098] (A1) The vehicle component performance data and vehicle failure frequency are used as the data to be analyzed in turn, and the diversity of the data to be analyzed is analyzed to obtain the diversity index.

[0099] (A2) Determine whether the diversity index is greater than the preset index threshold;

[0100] (A3) In response to the determination that the diversity index is not greater than the preset index threshold, the data type of the data to be analyzed is set to categorized.

[0101] (A4) In response to the determination that the diversity index is greater than the preset index threshold, the data type of the data to be analyzed is set to quantitative.

[0102] Assuming a preset index threshold of 0.7, vehicle component performance data is first used as the data to be analyzed. If the calculated Shannom diversity index for vehicle component performance data is 0.6, which is less than the preset index threshold, the data type of the vehicle component performance data is set to categorical. Next, vehicle failure frequency is used as the data to be analyzed. If the calculated Shannom diversity index for vehicle failure frequency is 0.8, which is greater than the preset index threshold, the data type of the vehicle failure frequency is set to quantitative.

[0103] In some embodiments, after determining whether the diversity index is greater than a preset index threshold, the method further includes:

[0104] (B1) In response to the determination that the diversity index is greater than the preset index threshold, discretization detection is performed on the data to be analyzed to determine the number of categories of the data to be analyzed;

[0105] (B2) Determine whether the number of categories is greater than a preset quantity threshold;

[0106] (B3) In response to the determination that the number of categories is greater than a preset quantity threshold, the data type of the data to be analyzed is set to quantitative; or

[0107] (B4) In response to the determination that the number of categories is not greater than a preset quantity threshold, the data type of the data to be analyzed is set to categorized.

[0108] Furthermore, in response to the determination that the diversity index is greater than a preset threshold, the data to be analyzed can be further analyzed to more accurately determine its data type. Discretization detection is performed on the data to be analyzed to determine whether it has significant discretization characteristics, such as containing only a small number of different values.

[0109] In some embodiments, the step of discretizing the data to be analyzed and determining the number of categories of the data to be analyzed includes:

[0110] (C1) Perform deduplication on the data to be analyzed to obtain deduplicated data;

[0111] (C2) Determine the number of categories of data to be analyzed based on the amount of deduplicated data.

[0112] First, the data to be analyzed is deduplicated, that is, duplicate values ​​are removed to obtain deduplicated data containing unique values. Then, based on the amount of deduplicated data, the number of categories of the data to be analyzed is determined. In one embodiment, the deduplicated data can be sorted, for example, by sorting the unique values ​​in the deduplicated data in ascending order or descending order. Then, the number of unique values ​​is counted, and this number of unique values ​​is set as the number of categories of the data to be analyzed.

[0113] For example, suppose the preset quantity threshold is 10. If the number of categories in the data to be analyzed is 8, since the number of categories is not greater than the preset quantity threshold, the data is determined to have strong discretization characteristics, and therefore the data type is set to categorical. If the number of categories in the data to be analyzed is 12, since the number of categories is greater than the preset quantity threshold, the data is determined to not have strong discretization characteristics, and therefore the data type is set to quantitative.

[0114] This application's embodiments, through analysis and discretization detection of the diversity of vehicle component performance data and vehicle fault frequencies, can automatically and accurately identify the data type. For example, when the vehicle component performance data is engine temperature data, diversity analysis and discretization detection determine whether the engine temperature data is continuous quantitative data or data with discrete characteristics. If the engine temperature data is highly discrete, such as having only a limited number of high-temperature alarms, then the engine temperature data is considered categorized data.

[0115] Step S102: Determine whether both the vehicle component performance data type and the vehicle fault frequency type are quantitative.

[0116] Determine whether both the vehicle component performance data type and the vehicle fault frequency type are quantitative. In response to determining that both the vehicle component performance data type and the vehicle fault frequency type are quantitative, proceed to step S103. In response to determining that at least one of the vehicle component performance data type and the vehicle fault frequency type is not quantitative, proceed to step S105.

[0117] Step S103: Perform a normality test on the vehicle component performance data and vehicle failure frequency to obtain the normality test results.

[0118] By generating QQ (Quantile-Quantile) plots, the distribution characteristics of each performance indicator are examined to determine whether standard statistical methods are suitable. For example, if the engine temperature data follows a roughly linear distribution, conforming to a normal distribution, then the Pearson correlation analysis algorithm is preferred. Otherwise, other suitable algorithms are used.

[0119] In one embodiment, the step of performing a normality test on vehicle component performance data and vehicle failure frequency to obtain the normality test result includes:

[0120] (D1) Determine the first fit between the data distribution of vehicle component performance data and the first theoretical normal distribution, and determine the second fit between the data distribution of vehicle fault frequency and the second theoretical normal distribution;

[0121] (D2) Determine the first normality test method based on the first fit, and determine the second normality test method based on the second fit; and

[0122] (D3) Perform a normality test on the vehicle component performance data according to the first normality test method, and perform a normality test on the vehicle fault frequency according to the second normality test method to obtain the normality test results.

[0123] A QQ plot can be generated using vehicle component performance data to determine the first fit between the data distribution and a theoretical normal distribution. If the points in the QQ plot are roughly distributed along a straight line, the first fit indicates that the vehicle component performance data values ​​are generally normal and close to a normal distribution; otherwise, the first fit indicates that the vehicle component performance data contains outliers.

[0124] Similarly, a QQ (Quantile-Quantile) plot can be generated using vehicle fault frequencies to determine the second fit between the data distribution of vehicle fault frequencies and the second theoretical normal distribution. If the points in the QQ plot are roughly distributed along a straight line, the second fit indicates that the vehicle fault frequency values ​​are roughly normal and close to a normal distribution; otherwise, the second fit indicates that there are outliers in the vehicle fault frequencies.

[0125] Next, based on the first fitting result, a first normality test method is determined for testing the normality of vehicle component performance data, and based on the second fitting result, a second normality test method is determined for testing the normality of vehicle fault frequency.

[0126] If the first fitting condition is that the vehicle component performance data contains outliers, then the first normality test method is determined to be the Shapiro-Wilk test. If the first fitting condition is that the vehicle component performance data values ​​are roughly normal and close to a normal distribution, then the first normality test method is determined to be the Kolmogorov-Smirnov test. Among these, the Shapiro-Wilk test performs better than the Kolmogorov-Smirnov test when dealing with small samples or the presence of outliers.

[0127] Similarly, if the second fitting condition is that there are outliers in the vehicle fault frequency, then the second normality test method is determined to be the Shapiro-Wilk test. If the second fitting condition is that the vehicle fault frequency values ​​are roughly normal and close to a normal distribution, then the second normality test method is determined to be the Kolmogorov-Smirnov test.

[0128] The system can automatically recommend suitable algorithms based on data type and normality detection results. For example, when analyzing the relationship between engine temperature data and fault frequency data, if the data is quantitative and conforms to a normal distribution, the Pearson correlation coefficient is recommended. When fuel consumption is quantitative data and braking status is categorical data, the Spearman rank correlation coefficient is recommended. This approach ensures the applicability of the algorithm and the reliability of the analysis results. A detailed explanation follows:

[0129] Step S104: Based on the normality test results, determine the first correlation analysis algorithm for performing correlation analysis on vehicle component performance data and vehicle fault frequency.

[0130] In some embodiments, based on the normality test results, a first correlation analysis algorithm step is determined for performing correlation analysis on vehicle component performance data and vehicle failure frequency, including:

[0131] (E1) Determine whether the normality test results are both vehicle component performance data and vehicle failure frequency conforming to a normal distribution;

[0132] (E2) In response to the determination that the normality test results show that both the vehicle component performance data and the vehicle fault frequency conform to a normal distribution, a first preset correlation analysis algorithm is selected as the algorithm for performing correlation analysis on the vehicle component performance data and the vehicle fault frequency; or

[0133] (E3) In response to the determination that the normality test results show that the vehicle component performance data and vehicle fault frequency do not conform to a normal distribution, a second preset correlation analysis algorithm is determined as the algorithm for performing correlation analysis on the vehicle component performance data and vehicle fault frequency.

[0134] For example, if the normality test results indicate that the vehicle component performance data and vehicle failure frequency conform to a normal distribution, then the Person correlation analysis algorithm is selected as the first preset correlation analysis algorithm for correlation analysis. If the normality test results indicate that the vehicle component performance data and vehicle failure frequency do not conform to a normal distribution, then the Spearman correlation analysis algorithm is selected as the second preset correlation analysis algorithm for correlation analysis.

[0135] Step S105: Determine a second correlation analysis algorithm for performing correlation analysis on vehicle component performance data and vehicle failure frequency.

[0136] In some embodiments, in response to determining that at least one of the vehicle component performance data type and the vehicle fault frequency type is not quantitative, a second correlation analysis algorithm step is determined for performing a correlation analysis on the vehicle component performance data and the vehicle fault frequency, including:

[0137] (F1) In response to the determination that the vehicle component performance data type and the vehicle fault frequency type are both classified, a third preset correlation analysis algorithm is determined as the algorithm for performing correlation analysis on the vehicle component performance data and the vehicle fault frequency.

[0138] (F2) In response to determining that the vehicle component performance data type is categorical and the vehicle fault frequency type is quantitative, a second preset correlation analysis algorithm is determined as the algorithm for performing correlation analysis on the vehicle component performance data and the vehicle fault frequency; or

[0139] (F3) If the vehicle component performance data type is quantitative and the vehicle fault frequency type is categorical, a second preset correlation analysis algorithm is determined as the algorithm for performing correlation analysis on the vehicle component performance data and the vehicle fault frequency.

[0140] For example, in response to determining that both the vehicle component performance data type and the vehicle fault frequency type are categorical, Kendall's Tau correlation analysis algorithm is selected as the third preset correlation analysis algorithm for correlation analysis. In response to determining that one of the vehicle component performance data type and the vehicle fault frequency type is categorical and the other is quantitative, the Spearman correlation analysis algorithm is selected as the second preset correlation analysis algorithm for correlation analysis.

[0141] Step S106: Obtain the correlation between vehicle component performance data and vehicle fault frequency according to the first correlation analysis algorithm or the second correlation analysis algorithm.

[0142] Through the aforementioned data processing flow and efficient algorithms, significant correlations between different performance indicators and fault frequencies can be quickly identified. For example, if there is a high correlation between engine temperature and brake failure, the vehicle will be marked as high-risk, indicating the need for further inspection. For abnormal data, such as anomalies like excessively high temperatures, alarms or optimization suggestions will be automatically generated to help optimize the design before the vehicle is put on the market.

[0143] In some embodiments, correlation analysis results can also be obtained, and correlation analysis charts can be determined based on vehicle component performance data types and vehicle fault frequency types; then, the correlation analysis results can be displayed through the correlation analysis charts.

[0144] After analyzing vehicle component performance data and vehicle failure frequencies using correlation analysis algorithms, correlation analysis charts can be determined based on the data types of vehicle component performance and vehicle failure frequencies to display the correlation analysis results. These correlation analysis charts include at least one of the following: scatter plots, box plots, bar plots, and / or correlation matrices.

[0145] For example, when both vehicle component performance data and vehicle failure frequency data are quantitative, a scatter plot can be used to visually display the relationship between the two data columns. When presenting the correlation analysis results using a scatter plot, the correlation coefficient and p-value can also be labeled. Conversely, when both vehicle component performance data and vehicle failure frequency data are categorical, a box plot or bar plot can be used.
