S120, generating a fault data screening table according to the automobile quality data. Wherein the failure data screening table is used for representing the relationship between the vehicle attribute data and the vehicle service data.
The fault data screening table can be used for carrying out statistical screening on fault data of the vehicle attribute data under different conditions. It should be noted that at least one fault data filtering table may be generated according to the vehicle quality data. For example, the fault data filtering table may be a fault frequency statistics of each failure part on different production dates, a fault frequency statistics of each vehicle model on different fault dates, a fault frequency statistics of each failure part on different areas, a fault frequency statistics of each failure part on different fault mileage, a fault frequency statistics of each vehicle model on different production dates, and so on. The embodiment of the invention is not limited, and can be determined according to actual needs.
As an alternative but non-limiting implementation, generating a fault data screening table according to the vehicle quality data includes, but is not limited to, the following steps A1-A2:
and A1, selecting target row data, target column data, target values and target screening options from the automobile quality data.
The target line data can be various failure pieces, vehicle models or product models, so that trend statistics can be conveniently carried out on different failure pieces, vehicle models or product models; the target column data can be the dividing condition of the failure frequency of each failure piece, vehicle type or product model; the target value can be an accumulated value of failure frequency of the target line data under a specific screening condition; the target screening item can be a screening condition of failure frequency of each failed part, vehicle model or product model. Specifically, the target row data may be selected from the vehicle attribute data, and the target column data, the target value, and the target screening item may be selected from the vehicle quality data.
In the embodiment of the invention, the selection principle of the target row data, the target column data, the target value and the target screening item can be determined according to the type of the fault data screening table. For example, if the failure data filtering table is the failure frequency statistics of each failure piece on different production dates, the target row data is each failure piece, the target column data is each production date, the target value is the failure frequency value, and the target filtering item is the product platform and the data validity. Also, for example, if the fault data filtering table is a fault frequency statistic of each vehicle model on different fault dates, the target row data is each vehicle model, the target column data is each fault date, the target value is a fault frequency value, and the target filtering item is a product platform and data validity. Also, for example, if the failure data filtering table is a failure frequency statistics of each failure piece in different areas, the target row data is each failure piece, the target column data is each area, the target value is a failure frequency value, and the target filtering item is a product platform, data validity and production date.
And A2, generating a fault data screening table according to the target row data, the target column data, the target value, the target screening item and a preset calculation type of the target value.
The preset calculation type of the target value is counting, namely, the accumulated value of the failure frequency of the target line data under the specific screening condition can be counted. For example, when the failure data filtering table is a statistics of failure frequency of each failure part in different areas, if the obtained vehicle quality data includes failure part 1 of vehicle a, failure part 1 of vehicle B, failure part 2 of vehicle C in the beijing area, failure part 1 of vehicle D in the seagoing area, failure part 2 of vehicle E, the target values corresponding to failure part 1 and beijing area are 2, the target values corresponding to failure part 1 and the seagoing area are 1, the target values corresponding to failure part 2 and the beijing area are 1, and the target values corresponding to failure part 2 and the seagoing area are 1.
According to the embodiment of the invention, importing and filling can be carried out from the acquired automobile quality data in the automobile market in the first preset period according to the selected target row data, the target column data, the target value and the target screening item; the fault data screening table can be generated by calculating the target value based on the function of the pivot table.
It should be noted that the fault data filtering table may include a main filtering table and a custom filtering table, where the main filtering table is a fixed fault data filtering table, and the custom filtering table is a fault data filtering table that is personalized according to actual needs.
S130, predicting the cumulative failure frequency of the failure piece in a prediction time period according to the failure piece in the vehicle attribute data, and the production date, the using time length and the failure frequency value corresponding to the failure piece in the vehicle service data, and determining the predicted cumulative failure frequency of the failure piece.
Wherein the predicted time period may be the next time period to the current time, e.g., the current time period is 2023, 1 month, then the predicted time period may be 2023, 2 months. The cumulative failure frequency may be the frequency at which the failed piece has accumulated to fail before a certain period of time.
Specifically, according to the accumulated failure frequency values of the failure piece in different using time periods and different production dates, the increasing trend of the failure frequency of the failure piece along with the different using time periods can be obtained; and further predicting the accumulated failure frequency of the failure part in the predicted time period according to the failure frequency increasing trend of the failure part, so as to obtain the accumulated failure frequency of the failure part before the next time period.
And S140, determining a fault analysis result of the failure piece according to the fault data screening table and the predicted accumulated fault frequency.
The failure analysis result may be a failure frequency trend of the failed part before the current time period and a failure frequency trend after the current time period. Specifically, the fault data screening table and the predicted accumulated fault frequency can be subjected to statistical arrangement to obtain a data table of fault trends of related failure parts under different using time periods or different production dates, and the data table of fault trends can be further displayed in a chart mode.
As an alternative but non-limiting implementation, determining the failure analysis result of the failed component according to the failure data filtering table and the predicted cumulative failure frequency includes, but is not limited to, the following steps B1-B3:
and B1, marking the data which are larger than the first preset fault frequency in the fault data screening table to obtain a fault data screening identification table.
The first preset failure frequency can be standard data corresponding to the frequency data counted in the failure data screening table, and can be determined according to historical experience. It should be noted that, the first preset failure frequency and the failure data filtering table are in one-to-one correspondence, and when at least two failure data filtering tables exist, at least two first preset failure frequencies exist.
Specifically, the data with high absolute value, high ratio or large amplification of fault frequency in the fault data screening table can be identified, for example, the area of the data to be identified can be filled with other colors to carry out distinguishing identification.

As shown in fig. 3, the method of this embodiment specifically includes the following steps:

Wherein the first preset period is a preset period of time before the current time, the vehicle quality data comprises vehicle attribute data and vehicle service data, the vehicle attribute data is used for representing equipment inherent attribute data of a vehicle, and the vehicle service data is used for representing equipment maintenance service data of the vehicle
S220, generating a fault data screening table according to the automobile quality data; wherein the failure data screening table is used for representing the relationship between the vehicle attribute data and the vehicle service data.
S230, determining the accumulated failure frequency of different production dates corresponding to the failure piece in each use time according to the failure piece, the production date, the use time and the failure frequency value corresponding to the failure piece.
Specifically, firstly, the use time length of the failure piece corresponding to different production dates can be determined according to the failure date and the failure frequency value of the failure piece, secondly, a corresponding table of each production date and each use time length can be established, and finally, the accumulated failure frequency of the failure piece is counted according to each production date and each corresponding use time length.
Fig. 4 is a diagram illustrating a statistical representation of cumulative failure frequency provided in a second embodiment of the present application. As shown in fig. 4, the horizontal axis represents the date of production, the vertical axis represents the duration of use, and the table contents represent cumulative failure frequencies of the failure pieces corresponding to the date of production and the duration of use, respectively. For example, the content in 2003/0MIS indicates that a failure element has a cumulative failure frequency of 3 times during use for 3 months at 3 months in 2020 (i.e., 6 months before 2020); the content in 2003/1MIS indicates that a failure piece has a cumulative failure frequency of 50 times over 4 months of use at 3 months of 2020; the content in 2004/12MIS indicates that a failure element has a cumulative failure frequency of 539 times during 15 months of use at 4 months of 2020.

Specifically, the cumulative failure frequency of the failure piece in the prediction time period can be predicted according to the change rule of the cumulative failure frequency corresponding to different use time periods of the failure piece in the same production date, or according to the change rule of the cumulative failure frequency corresponding to different production dates of the failure piece in the same use time period, so as to determine the predicted cumulative failure frequency of the failure piece.
The change rule of the accumulated failure frequency can be obtained by performing linear fitting on each accumulated failure frequency, so that a change function of the accumulated failure frequency is obtained, and further, the predicted accumulated failure frequency of the failure piece in a predicted time period is determined according to the change function. Of course, the embodiment of the invention does not limit the change rule of the accumulated failure frequency, and can also determine the ratio of the accumulated failure frequency between adjacent production dates or the ratio of the accumulated failure frequency between adjacent use periods, and the like.
As an optional but non-limiting implementation manner, according to the accumulated failure frequency of the failure piece in each use time period corresponding to different production dates, the accumulated failure frequency of the failure piece in a predicted time period is predicted, and the predicted accumulated failure frequency of the failure piece is determined, which includes but is not limited to the following processes of steps C1-C2:
and C1, selecting a target accumulated fault frequency from accumulated fault frequencies of different production dates corresponding to the time length of each use of the invalid piece according to the time length of each use, and determining the average growth rate of the accumulated fault frequency of the invalid piece according to the target accumulated fault frequency. The target accumulated fault frequency is a preset number of accumulated fault frequencies which are closest to the time interval of the predicted time period and are continuous and effective in production date and correspond to each using time period.
The effective means that the accumulated failure frequency is the data which actually occurs and is fixed. For example, as illustrated in fig. 4, the current time period is 2110 (i.e., 2021, 10 months), the predicted time period may be 2021, 11 months, 0MIS refers to the cumulative failure frequency of the failed part during 3 months of use, and the effective cumulative failure frequency in 0MIS is the data before the date of production is 2107 (i.e., 2021, 07 months). Similarly, the effective cumulative failure frequency in 1MIS is data prior to date 2106 (i.e., 2021, month 06); the cumulative failure frequency valid in 2MIS is data before date of production 2105 (i.e., month 05 of 2021) until the cumulative failure frequency valid in 12MIS is data before date of production 2007 (i.e., month 07 of 2020).
Illustratively, and as illustrated by way of example in FIG. 4, the current time period is 2021, 10 months, and the predicted time period is 2021, 11 months, as shown in FIG. 4.
First, for 0MIS to 12MIS, a cumulative failure frequency with consecutive and valid production dates in the last 5 months from the 11 months of 2021, which is the data included in the hatched portion in fig. 4, is selected from cumulative failure frequencies of different production dates corresponding to the time period of each use of the failure piece.
And secondly, calculating the ratio of the accumulated fault frequency of the current use time length to the accumulated fault frequency of the last use time length in the same production date respectively, and taking the ratio as the candidate growth rate of the accumulated fault frequency of the current production date in different use time lengths.

As shown in fig. 5a, 0MIS/0MIS at the same date of production is taken as the candidate growth rate of 0MIS at the date of production, 1MIS/0MIS is taken as the candidate growth rate of 1MIS at the date of production, 2MIS/1MIS is taken as the candidate growth rate of 2MIS at the date of production, and the calculation result of the candidate growth rate shown in fig. 5a is obtained by the same method.
And thirdly, respectively carrying out summation and average on candidate growth rates of the failure piece accumulated failure frequency in different production dates of the same using time length to obtain the average growth rate of the failure piece accumulated failure frequency.
Fig. 5b is a schematic diagram illustrating calculation of an average growth rate according to an embodiment of the present application. As shown in fig. 5b, the candidate growth rates that are continuous and effective in production date in the last 5 months from 11 months of 2021 are summed and averaged, respectively, for example, in 1MIS, the candidate growth rates 1, 2, 2.25, 3 and 0 from 2 months to 6 months of 2021 are summed and averaged to obtain 1.65, and the calculation result of the average growth rate as shown in fig. 5b is obtained by the same.
And C2, predicting the failure frequency of the failure piece in the prediction time period according to the average growth rate and the target accumulated failure frequency, and determining the predicted accumulated failure frequency of each failure piece.
Specifically, the predicted cumulative failure frequency of the failure piece under the use duration in the predicted time period can be determined according to the average growth rate of the same use duration and the cumulative failure frequency of the target cumulative failure frequency, wherein the cumulative failure frequency is closest to the time interval of the predicted time period in the use duration and is continuous and effective in production date.
Fig. 5c is a schematic diagram illustrating calculation of a predicted cumulative failure frequency according to an embodiment of the present application. As shown in fig. 5c, the cumulative failure frequency of the failure part, which is 1 month more recently from 2021, 11, and is effective, and the average growth rate calculated in fig. 5b are multiplied to obtain the predicted cumulative failure frequency of the failure part.
After determining the predicted cumulative failure frequency of each failure piece, the predicted cumulative failure frequency can be compared with the actual cumulative failure frequency fed back, and the maximum assignment is obtained.
The technical scheme has the beneficial effects that the accumulated fault frequency of the prediction time period in different use periods is predicted, and the accuracy of predicting the trend of the long fault index in each use period is improved.
S250, determining a fault analysis result of the failure piece according to the fault data screening table and the predicted accumulated fault frequency.
The embodiment of the invention provides a processing method of automobile quality data, which comprises the steps of obtaining the automobile quality data in an automobile market in a first preset period; the vehicle quality data comprises vehicle attribute data and vehicle service data, wherein the vehicle attribute data is used for representing equipment inherent attribute data of a vehicle, and the vehicle service data is used for representing equipment maintenance service data of the vehicle; generating a fault data screening table according to the automobile quality data; wherein the fault data screening table is used for representing the relation between the vehicle attribute data and the vehicle service data; determining the cumulative failure frequency of the failure piece on different production dates corresponding to each use time according to the failure piece and the production date, the failure date and the failure frequency value corresponding to the failure piece; predicting the cumulative failure frequency of the failure piece in a prediction time period according to the cumulative failure frequency of the failure piece in each use time period, and determining the predicted cumulative failure frequency of the failure piece; and determining a fault analysis result of the failure piece according to the fault data screening table and the predicted accumulated fault frequency. According to the technical scheme, the accumulated fault frequency of the prediction time period in different use periods is predicted, and the accuracy of predicting the trend of the long fault index in each use period is improved.
On the basis of the above embodiments, after determining the failure analysis result of the failed component according to the failure data filtering table and the predicted cumulative failure frequency, the method further includes: counting the failure frequency of parts which do not fail in each service station from the automobile quality data; if the service station with the failure frequency of the non-failure part being greater than the second preset failure frequency exists, determining the service station as a target service station, and performing special training and management control on the target service station.
The non-faulty component may be a component that is repaired and replaced during service, but analyzed by the vehicle manufacturer or component manufacturer to meet the "good" requirements.
Specifically, in the first step, the number of faults of non-faulty (No valid Found) parts in each area can be screened from a three-pack claim system in the market, the sales number of products in each area is generated by using a vehicle information screening table in each area, and then the number of faults of the NTF parts is divided by the sales number of products in each area, so that thousands of frequency of faults of the NTF in each area can be obtained; and secondly, screening the areas with more NTF faults in the vehicle information screening table of each area to serve as key areas, adopting a three-pack claim system in the market to further screen vehicle maintenance service stations, and taking the service stations with failure frequencies of non-failure parts larger than the second preset failure frequencies as target service stations to perform special training and management control on the target service stations.
The technical scheme has the advantages that the quality data of the NTF parts with large market claim ratio can be subjected to special analysis, and the key areas or vehicle maintenance service stations with more NTF faults are identified, so that a service department is guided to conduct special guidance and enhanced management and control on the abnormal claim service stations, containment measures are quickly taken, and market claim and user complaints are reduced.

Specifically, for example, the parts having seasonal faults such as an air-conditioning compressor are used frequently in summer or winter and used frequently in spring or autumn, so that when the frequency of faults of the parts is counted for one year or less, the change rule of the frequency of faults is not easily obtained for the parts having seasonal faults, and effective production guidance advice cannot be provided for the parts having seasonal faults.
In view of the above, for such a failure part with seasonal faults, the embodiment of the present application counts the target vehicle quality data in a period exceeding a general statistical period, for example, the first preset period (i.e., the general statistical period) is 12 months, and the second preset period may be 18 months; and further, the fault frequency and the variation amplitude are analyzed in a time axis transverse ratio mode, so that more accurate evaluation and suggestion can be obtained.
The technical scheme has the beneficial effects that the special data analysis can be carried out on the parts with seasonal faults so as to output more accurate evaluation and further judge the fault risk more timely and accurately.
