Description

Technical Field

[0001] The present invention relates to the technical field of vehicle maintenance, and in particular to a vehicle maintenance method based on reshaped accessories and related equipment. Background Art

[0002] The taxi industry generally purchases a large number of vehicles of the same specifications and deploys them in multiple regions for operation. Therefore, taxis are used more frequently than ordinary private cars and need to face more complex and diverse driving environments. At the same time, the number of taxis is huge. When the taxi industry faces a large number of maintenance needs, in order to reduce costs, it often seeks more reliable maintenance suggestions from repair shops.

[0003] In real life, when a vehicle breaks down, the cause of the failure may come from different parts. In the existing maintenance method, after finding the faulty part, it is generally simply replaced with a spare part that is exactly the same as the faulty part. However, for the taxi industry, the failure of parts is likely to be related to the environment of the operating site. For example, the failure of the vehicle's abnormal noise may be caused by the bumpy road surface in the operating site, which causes damage to the shock absorber, or it may be that the operating site is mostly gravel roads, causing serious wear on the tire surface. Simply replacing the faulty part with a spare part that is exactly the same as the faulty part can repair the fault, but it can only restore the taxi to its original reliability and life span, and cannot adaptively improve the reliability and service life of the taxi according to the operating site.

[0004] Therefore, the current maintenance methods cannot provide the taxi industry with more advanced maintenance strategies, and there is still a lot of room for improvement in maintenance services for the taxi industry. Summary of the invention

[0005] The purpose of the present invention is to provide a vehicle maintenance method and related equipment based on reshaped accessories, which solves the problem that the existing maintenance methods cannot provide the taxi industry with more advanced maintenance strategies, and provides users with advanced maintenance suggestions that are adapted to the region, which is conducive to improving users' recognition and trust in the maintenance party.

[0006] In a first aspect, the present invention provides a vehicle repair method based on remodeling parts, comprising the following steps: S1. Based on the historical fault data of multiple different regions, the faulty parts that cause the corresponding faults in each region and are associated with the corresponding region are divided according to the fault type and used as vulnerable parts in the corresponding region; S2. When inspecting a faulty vehicle with the same fault type, each repair shop in the region determines the faulty parts that caused the corresponding fault of the faulty vehicle and uses them as target parts; S3. Determine whether the target part is a vulnerable part in the current region, and if so, prompt the maintenance personnel to replace the target part with a corresponding reshaped part to repair the corresponding fault, and if not, prompt the maintenance personnel to replace the target part with a corresponding spare part to repair the corresponding fault; the performance of the reshaped part is better than that of the corresponding spare part.

[0007] The vehicle maintenance method based on reshaped parts provided by the present invention takes into account that different vehicle parts are affected differently by the regional environment, and obtains vulnerable parts that are obviously related to the region by analyzing fault data, and obtains two different maintenance strategies with vulnerable parts as the core. This can provide users with advanced maintenance suggestions that adapt to regional characteristics, achieve more advanced maintenance services, and help the maintenance party gain recognition and trust from users.

[0008] Furthermore, the specific steps in step S1 include: S11. Obtaining historical fault data of the same fault type in multiple different regions; the historical fault data includes the number of faults of each faulty accessory causing the corresponding fault; S12. Compare the failure times of the same faulty parts in each of the historical fault data to determine whether there is a correlation between each of the faulty parts and each of the regions, and respectively use the faulty parts in each of the regions that are correlated with the corresponding region as vulnerable parts of the corresponding region.

[0009] By obtaining historical failure data from multiple regions and comparing and analyzing the number of failures of faulty parts in different regions, it is possible to objectively determine whether certain parts are associated with specific regions. This correlation determination provides a reliable basis for determining vulnerable parts, thereby significantly improving the accuracy of vulnerable parts classification.

[0010] Furthermore, the specific steps in step S2 include: S21. If some vulnerable parts of the faulty vehicle in the current area have been replaced with corresponding reshaped parts, prompt the maintenance personnel to determine the target parts according to the first sequence; the first sequence is: first check the vulnerable parts that have not been replaced with reshaped parts, then check other parts except all the vulnerable parts, and finally check the vulnerable parts that have been replaced with reshaped parts; S22. If all the vulnerable parts of the faulty vehicle in the current area have been replaced with corresponding reshaped parts, prompt the maintenance personnel to determine the target parts according to the second sequence; the second sequence is: first check all the vulnerable parts except all the vulnerable parts, and finally check the vulnerable parts that have been replaced with reshaped parts; S23. If all the vulnerable parts of the faulty vehicle in the current area have not been replaced with corresponding reshaped parts, the maintenance personnel are prompted to determine the target parts according to the third sequence; the third sequence is: first check all the vulnerable parts, and finally check other parts except all the vulnerable parts.

[0011] By considering the use of vulnerable parts, reshaped parts and geographical factors, a more targeted and efficient fault diagnosis method is provided. This can not only shorten the maintenance time, but also improve the accuracy of fault diagnosis, thereby reducing the misdiagnosis rate and return repair rate.

[0012] Furthermore, when checking other accessories except all the above-mentioned consumable accessories, the maintenance personnel are prompted to check according to the fourth order; the fourth order is: first check the accessories that are consumable accessories in other areas outside the current area and have not been replaced with corresponding reshaped accessories, and finally check the accessories that are consumable accessories in other areas outside the current area and have been replaced with corresponding reshaped accessories.

[0013] By prioritizing the inspection of high-risk but unupdated parts, the root cause of the fault can be located more quickly and accurately, greatly improving maintenance efficiency and accuracy.

[0014] Further, when checking for vulnerable parts that have not been replaced with reshaped parts, and when checking for all vulnerable parts, the following steps are performed: A1. Determine the adjacent regions of each region based on the historical fault data of each region; A2. If there is an adjacent region to the current region where the faulty vehicle is located, then check the vulnerable parts of the faulty vehicle in the current region based on the vulnerable parts in the current region where the faulty vehicle is located and the corresponding adjacent regions.

[0015] Furthermore, the specific steps in step A1 include: A11. Classify vulnerable parts in each region according to the assembly they belong to; A12. The multiple regions where the same vulnerable parts exist are regarded as adjacent regions.

[0016] Furthermore, the specific steps in step A2 include: A21. If there are multiple vulnerable parts in the adjacent areas that belong to the same assembly and serve as the vulnerable parts of multiple areas respectively, the assembly with multiple vulnerable parts will be taken as the target assembly, and the vulnerable parts of the faulty vehicle in the current area that belong to the target assembly will be checked first.

[0017] In a second aspect, the present invention provides a vehicle repair device based on a remodeling accessory, comprising: A classification module, for classifying, based on historical fault data of multiple different regions, faulty parts that cause corresponding faults in each region and are associated with the corresponding region according to the fault type and serving as vulnerable parts for the corresponding region; A determination module, used for each repair shop in the region to determine the faulty parts that cause the corresponding fault of the faulty vehicle and use them as target parts when inspecting the faulty vehicles with the same fault type; A prompt module is used to determine whether the target part belongs to the consumable part in the current area, and when the target part belongs to the consumable part in the current area, prompt the maintenance personnel to replace the target part with the corresponding reshaped part to repair the corresponding fault, and when the target part does not belong to the consumable part in the current area, prompt the maintenance personnel to replace the target part with the corresponding spare part to repair the corresponding fault; the performance of the reshaped part is better than the corresponding spare part.

[0018] The vehicle maintenance device based on reshaped accessories provided by the present invention realizes the precision and personalization of maintenance strategies, effectively improves the reliability and service life of the vehicle, and brings technological innovation to vehicle maintenance in the taxi industry.

[0019] In a third aspect, the present invention provides an electronic device comprising a processor and a memory, wherein the memory stores computer-readable instructions, and when the computer-readable instructions are executed by the processor, the steps of the vehicle repair method based on reshaping accessories provided in the first aspect are executed.

[0020] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the steps of the vehicle repair method based on remodeling parts as provided in the first aspect are executed.

[0021] From the above, it can be seen that the vehicle maintenance method based on reshaped parts provided by the present invention obtains the correlation between parts and regions in a certain fault according to the fault data of various regions, thereby determining the vulnerable parts affected by the region, so that when repairing the faulty vehicle, different maintenance suggestions can be provided to the user according to the relationship between the faulty parts and the vulnerable parts, thereby providing the user with advanced maintenance suggestions that adapt to regional characteristics, thereby improving the reliability and service life of the user's vehicle, and further helping to improve the user's recognition and trust in the maintenance party.

[0022] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by implementing the embodiments of the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the drawings.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0029] In the field of vehicle maintenance in the taxi industry, existing technologies face the technical bottleneck of being unable to accurately identify and specifically handle regional specific faulty parts. Traditional maintenance methods ignore the significant impact of different regional environments on the performance and reliability of vehicle parts, resulting in maintenance strategies that lack specificity and adaptability. Specifically, road conditions, climate, and usage characteristics in different regions will cause differentiated parts failure mechanisms, and existing technologies have not established an effective regional fault correlation analysis model, and are unable to accurately identify key parts that are prone to failure in different regions.

[0030] Taking the taxi operation in a certain city and a certain district as an example, there are significant differences in the geographical environment and road conditions of the two places. A certain city is dominated by flat urban roads, while a certain district is characterized by plateau mountain roads and complex terrain. In this context, taxis of the same model will show great wear and failure characteristics of accessories in different regions. For example, the shock absorber in a certain city has a long service life, but in a certain district, the shock absorber may be damaged quickly due to bumpy road conditions. Traditional maintenance methods are difficult to capture this regional difference, and only using standard spare parts for replacement cannot improve the overall reliability and service life of the vehicle.

[0031] Inaccurate maintenance strategies will lead to frequent vehicle failures, increased maintenance costs, and difficulty in effectively extending the service life of vehicles. Blind replacement of parts will cause vehicle safety hazards and reduce the adaptability and reliability of vehicles in specific geographical environments.

[0032] The present invention provides a vehicle repair method based on remodeling parts, comprising the following steps: S1. Based on the historical fault data of multiple different regions, the faulty parts that cause the corresponding faults in each region and are related to the corresponding region are divided according to the fault type and used as the vulnerable parts of the corresponding region; S2. When repair shops in each region inspect faulty vehicles with the same fault type, they determine the faulty parts that caused the corresponding fault of the faulty vehicle and use them as target parts; S3. Determine whether the target part is a vulnerable part in the current region, and if so, prompt the maintenance personnel to replace the target part with a corresponding reshaped part to repair the corresponding fault, and if not, prompt the maintenance personnel to replace the target part with a corresponding spare part to repair the corresponding fault; the performance of the reshaped part is better than the corresponding spare part.

[0033] The traditional method of simply replacing spare parts of the same model cannot solve the problem of repeated failures caused by the regional environment. Therefore, this embodiment proposes the concept of "reshaped accessories" with better performance for the identified regional-specific vulnerable accessories, that is, upgraded accessories optimized for specific regional environments. This method can not only repair faults, but also improve the adaptability of vehicles in specific environments.

[0034] The vehicle maintenance method based on reshaped parts proposed in this application first divides the vulnerable parts unique to each region according to the type of fault based on historical fault data of multiple different regions. In actual maintenance, the repair shop determines the specific parts that caused the fault and determines whether it is a vulnerable part in the region. If it is, it is replaced with a reshaped part with better performance; if it is not, ordinary spare parts are used. This method effectively improves the reliability and service life of the vehicle by distinguishing regional characteristics and using reshaped parts in a targeted manner.

[0035] In specific implementation, the analysis of historical failure data is the key. Various data mining algorithms, such as association rule analysis and cluster analysis, can be used to find the correlation between component failure and regional environment. When the failure frequency of a certain component in a specific region is significantly higher than that in other regions, it is determined to be a vulnerable component in that region.

[0036] When determining the target parts, maintenance personnel can use a variety of diagnostic methods, such as OBD diagnosis, sensor data analysis, etc. To improve the accuracy of diagnosis, a comprehensive judgment can be made based on factors such as vehicle mileage and usage time.

[0037] The design of reshaped parts needs to take into full consideration the regional characteristics. For example, in plateau areas, engine parts can be optimized for the thin air; in coastal areas, the corrosion resistance of parts can be enhanced. The performance indicators of reshaped parts should be significantly better than ordinary spare parts, such as extending the service life by more than 30%, or improving the reliability in extreme environments by more than 50%.

[0038] In actual applications, there is a close logical connection between these steps. Historical data analysis provides the basis for the identification of vulnerable parts, which directly affects the maintenance decision. The use of reshaped parts not only solves the current fault, but also prevents similar faults that may occur in the future, forming a closed-loop optimization process.

[0039] Through this method, taxi companies can formulate targeted maintenance strategies based on the characteristics of different regions, effectively reducing maintenance frequency and costs. For example, in mountainous areas with complex road conditions, priority can be given to restocking suspension system remodeling parts; in high-temperature areas, focus can be placed on upgrading the cooling system. This precise maintenance strategy not only improves vehicle reliability, but also significantly extends the service life of vehicles, bringing practical economic benefits to taxi companies.

[0040] In one embodiment, a taxi company operates a large number of taxis of the same model in a city and a district. The company uses the maintenance method of the present application to improve the reliability and service life of vehicles. First, the vehicle failure data of the two places in the past three years were collected, including information such as failure type, faulty parts, and failure frequency. Through data analysis, it was found that the frequency of air filter replacement in a city area was significantly higher than that in a district, while the shock absorber failure rate in a district was significantly higher than that in a city.

[0041] Based on this data, the system identified the air filter as a vulnerable part in a certain city area, and the shock absorber as a vulnerable part in a certain district. When a taxi in a certain city was taken to the factory for repair due to engine performance degradation, the maintenance personnel determined that the air filter was clogged and caused the failure. The system determined that the air filter was a vulnerable part in a certain city area, so it prompted the maintenance personnel to replace it with a specially designed reshaped air filter. This reshaped part uses more efficient filtering materials and structural design, which can better deal with the air pollution problem in a certain city and extend the service life by about 50%.

[0042] In contrast, when a taxi in a certain district was sent to the factory for repair due to abnormal noise in the suspension system, the maintenance personnel determined that the shock absorber was damaged. The system determined that the shock absorber was a vulnerable part in a certain district and prompted the use of a reshaped shock absorber designed specifically for plateau road conditions. This shock absorber uses more wear-resistant materials and a stronger buffer structure, which can better adapt to the bumpy road conditions in a certain district and extend its service life by about 40%.

[0043] Through this targeted maintenance strategy, the taxi company has significantly improved the adaptability and reliability of vehicles in different geographical environments. The frequency of vehicle maintenance due to air filter problems in a certain city area has been reduced by about 30%, and the frequency of maintenance due to shock absorber problems in a certain district has been reduced by about 25%. This not only reduces maintenance costs, but also improves the operational efficiency of vehicles.

[0044] Compared with traditional maintenance methods, this technical solution has obvious advantages. Traditional methods usually use spare parts with unified standards, ignoring the impact of regional environmental differences on the life of parts. For example, using ordinary shock absorbers in a certain area may cause frequent damage due to inability to adapt to plateau road conditions, resulting in repeated vehicle repairs. This application effectively solves this problem by analyzing historical data to identify vulnerable parts and using targeted reshaped parts.

[0045] In addition, the method of this application is adaptive. As new fault data continues to accumulate, the system can dynamically update the list of vulnerable parts in each region, so that the maintenance strategy always remains targeted and timely. This data-driven maintenance method not only improves the accuracy of maintenance, but also provides important data support for taxi companies' fleet management, helping to optimize vehicle configuration and operation strategies.

[0046] In general, this application achieves precision and personalization of maintenance strategies by introducing regional factors and reshaping the concept of accessories, effectively improving the reliability and service life of vehicles, and bringing technological innovation to vehicle maintenance in the taxi industry.

[0047] In some embodiments, the specific steps in step S1 include: S11. Obtain historical fault data for the same fault type in multiple different regions; the historical fault data includes the number of faults of each faulty accessory causing the corresponding fault; S12. Compare the failure times of the same faulty parts in each historical fault data to determine whether there is a correlation between each faulty part and each region, and respectively use the faulty parts in each region that are correlated with the corresponding region as vulnerable parts of the corresponding region.

[0048] In some of the above-mentioned embodiments, during the implementation of the present application, there is still a problem of how to more accurately determine the vulnerable parts in each region when the vulnerable parts are divided based on the historical failure data of multiple different regions.

[0049] In this regard, the present application further proposes a technical solution of obtaining historical fault data of the same fault type in multiple different regions, and comparing the number of failures of the same faulty accessories in each historical fault data, so as to determine whether there is a correlation between each faulty accessory and each region, and respectively using the faulty accessories in each region that are associated with the corresponding region as the vulnerable accessories of the corresponding region.

[0050] The main technical features involved in this application include obtaining historical fault data of the same fault type in multiple different regions, comparing the number of faults of the same faulty parts in each historical fault data, determining whether there is a correlation between each faulty part and each region, and using the faulty parts associated with the corresponding region as the vulnerable parts of the region. These features work together to achieve the goal of more accurately determining the vulnerable parts in each region.

[0051] In specific implementation, obtaining historical fault data for the same fault type in multiple different regions can be achieved in a variety of ways. For example, a central database can be established, and repair shops in various regions can regularly upload fault repair records; or fault data can be collected in real time through the on-board diagnostic system. Historical fault data not only includes the number of faults of the faulty parts, but also includes information such as the time when the fault occurred, the vehicle model, and the mileage, to provide a more comprehensive analysis basis.

[0052] When comparing the number of failures of the same faulty parts in various historical failure data, a variety of statistical analysis methods can be used. For example, the failure frequency of each part in each region can be calculated and variance analysis can be performed; machine learning algorithms, such as decision trees or random forests, can also be used to identify the correlation pattern between part failures and regions. This comparative analysis not only considers the simple number of failures, but can also combine other factors, such as climate conditions, road conditions, etc., to conduct multi-dimensional correlation analysis.

[0053] When determining whether there is a correlation between each faulty part and each region, a correlation threshold can be set. For example, if the fault frequency of a part in a specific region is significantly higher than that in other regions (such as more than 50% higher), then the part is considered to be associated with the region. This threshold can be adjusted according to actual conditions to balance the accuracy and sensitivity of recognition.

[0054] The step of identifying the faulty parts associated with the corresponding region as vulnerable parts in that region is actually a comprehensive application of the previous analysis results. A vulnerable parts list can be established for each region and updated regularly. This list can be further subdivided into three vulnerable levels: high, medium, and low, so that maintenance personnel and vehicle managers can perform preventive maintenance more targetedly.

[0055] For example, for the same faulty accessories, the number of failures in each region is compared with the minimum number of failures in all regions to obtain the failure ratio of each region. The regions with failure ratios greater than a preset value are associated with the faulty accessories, and the same process is performed on other faulty accessories. In this way, each faulty accessory is associated with each region to obtain the vulnerable accessories in each region.

[0056] There is a close logical connection between these features. The acquisition of historical fault data provides the basis for subsequent analysis; data comparison and correlation judgment are the core analysis process; finally, the analysis results are applied to the determination of vulnerable parts, forming a complete data-driven decision-making process. This method not only considers the failure frequency of faulty parts, but also pays attention to the impact of regional factors on part failure, so that vulnerable parts in various regions can be identified more accurately.

[0057] The technical solution of this application effectively solves the problem of how to accurately determine the vulnerable parts in each region through systematic data collection and analysis. By obtaining historical failure data from multiple regions and comparing and analyzing the number of failures of faulty parts in different regions, it is possible to objectively determine whether certain parts are associated with specific regions. This correlation judgment provides a reliable basis for determining vulnerable parts, thereby significantly improving the accuracy of the classification of vulnerable parts.

[0058] For example, in a specific embodiment, suppose we have collected the fault data of the same model of taxis in three regions, A, B, and C, over the past year. The data shows that in region A, the number of shock absorber failures is three times that of the other two regions; in region B, the number of air conditioning compressor failures is 2.5 times that of the other two regions; and in region C, the wear rate of brake pads is 80% higher than that of the other two regions. By setting the correlation threshold to 2 (i.e., the failure frequency is more than twice that of other regions), we can determine that shock absorbers are vulnerable parts in region A, air conditioning compressors are vulnerable parts in region B, and brake pads are vulnerable parts in region C.

[0059] Based on these analysis results, repair shops can adjust spare parts inventory in a targeted manner, such as repair shops in region A can stock more high-performance shock absorbers. At the same time, fleet managers can formulate more targeted maintenance plans, such as more frequent inspection and replacement of brake pads in region C. This not only improves maintenance efficiency, but also effectively reduces vehicle failure rate and maintenance costs.

[0060] Compared to the prior art that simply uses a unified list of wearing parts, the method of the present application takes into account the impact of regional factors on accessory failures and can more accurately identify wearing parts in each region. This method not only improves the pertinence and efficiency of maintenance, but also helps vehicles better adapt to the operating environment of different regions, extends the service life of the vehicle, and reduces overall maintenance costs. For example, in traditional methods, shock absorbers may be uniformly listed as wearing parts in all regions, but in fact, only in region A with poor road conditions do shock absorbers really need special attention. The method of the present application can identify this difference, thereby avoiding excessive attention or replacement of unnecessary accessories in other regions, which not only saves costs, but also ensures that the accessories that really need to be focused on are maintained in a timely manner.

[0061] Through this more accurate identification method of vulnerable parts, this application not only improves the pertinence and efficiency of vehicle maintenance, but also provides a reliable basis for the subsequent reshaping of parts replacement strategies. This has important practical application value for large-scale fleet management, especially for taxi companies operating across regions.

[0062] In some embodiments, the specific steps in step S2 include: S21. If some vulnerable parts of the faulty vehicle in the current area have been replaced with corresponding reshaped parts, the maintenance personnel are prompted to determine the target parts according to the first order; the first order is: first check the vulnerable parts that have not been replaced with reshaped parts, then check other parts except all vulnerable parts, and finally check the vulnerable parts that have been replaced with reshaped parts; S22. If all vulnerable parts of the faulty vehicle in the current area have been replaced with corresponding reshaped parts, the maintenance personnel are prompted to determine the target parts according to the second sequence; the second sequence is: first check other parts except all vulnerable parts, and finally check vulnerable parts that have been replaced with reshaped parts; S23. If all the vulnerable parts of the faulty vehicle in the current area have not been replaced with corresponding reshaped parts, the maintenance personnel are prompted to determine the target parts according to the third sequence; the third sequence is: first check all vulnerable parts, and finally check other parts except all vulnerable parts.

[0063] In some of the above-mentioned embodiments, during the implementation of the present application, there is still a problem of how to efficiently determine the target parts of the vehicle failure in different situations to improve the maintenance efficiency.

[0064] In this regard, the present application proposes three different situations to determine the troubleshooting order of target accessories, and these troubleshooting orders are determined according to the replacement of the vulnerable parts of the faulty vehicle. This method can improve maintenance efficiency: when some vulnerable parts have been replaced, the probability of the failure caused by the unreplaced vulnerable parts is higher, so the unreplaced vulnerable parts are prioritized, and it is more likely to find the cause of the failure faster. When all vulnerable parts have been replaced, the probability of other parts causing the failure is higher, so other parts are prioritized, and it is more likely to find the cause of the failure faster. When all vulnerable parts have not been replaced, the probability of the failure caused by the vulnerable parts is higher, so all vulnerable parts are prioritized, and it is more likely to find the cause of the failure faster. This classification troubleshooting method takes into account the possible location of the fault in different situations, which helps maintenance personnel find the source of the fault more quickly and accurately. By providing a clear troubleshooting order, the uncertainty and arbitrariness in the maintenance process are reduced, and the maintenance efficiency is improved. In addition, the method also takes into account the use of reshaped parts, and puts the parts that have been replaced with reshaped parts at the end of the inspection order, which reflects the confidence in the performance of reshaped parts, while also avoiding unnecessary repeated inspections and further optimizing the maintenance process. In general, this method provides a systematic and efficient fault diagnosis method for vehicle maintenance by formulating targeted inspection sequences according to different situations, combining the concept of vulnerable parts and the use of reshaped parts.

[0065] The troubleshooting order in this application can be flexibly adjusted according to the specific situation. For example, in step S21, the troubleshooting order can be further subdivided according to the number and importance of the vulnerable parts that have not been replaced. If there are a large number of vulnerable parts that have not been replaced, you can first sort them according to the frequency of failure of the accessories, and give priority to checking accessories with higher failure frequencies. In addition, you can also consider the importance and difficulty of replacement of accessories, and give priority to troubleshooting accessories with high importance and greater difficulty in replacement.

[0066] In step S22, when checking other accessories except all vulnerable accessories, the order of checking can be determined in combination with the vehicle's usage history and maintenance records. For example, non-vulnerable accessories that have been recently repaired or replaced can be checked first, because these accessories may have the risk of improper installation or quality problems.

[0067] For step S23, when checking all vulnerable parts, the order of checking can be adjusted in combination with the vehicle's mileage and usage environment. For example, for high-mileage vehicles, priority can be given to checking vulnerable parts related to mileage, such as tires, brake pads, etc. For vehicles used in special environments (such as deserts and high-cold areas), priority can be given to checking vulnerable parts related to the environment.

[0068] The method of the present application forms an organic whole with the previous steps. By combining the information of consumable parts determined in the previous steps and the usage of reshaped parts, the present method can guide the maintenance process more accurately. For example, the geographical factors are taken into account when determining consumable parts, which enables the present method to better adapt to the maintenance needs of different regions when applied. At the same time, by distinguishing between reshaped parts and ordinary parts, the present method can make full use of the advantages of reshaped parts and improve the overall effect of maintenance.

[0069] In practical applications, the method of the present application can be implemented through a maintenance management system. The system can automatically generate a suitable troubleshooting sequence based on the vehicle's historical maintenance records, current status, and regional information, and display it to maintenance personnel through mobile devices or display screens at maintenance stations. This can not only improve maintenance efficiency, but also reduce human judgment errors.

[0070] The specific implementation example is as follows: Assume that a taxi has an abnormal noise fault in a northern city. The system first checks the vehicle's parts replacement record and finds that the shock absorber of the suspension system has been replaced with a reshaped part, while the tire and brake pad have not been replaced. According to the method of this application, the system will generate the following troubleshooting sequence: 1. First check the vulnerable parts that have not been replaced: tires and brake pads.

[0071] 2. Then check other non-wearable parts, such as drive shaft, wheel hub, etc.

[0072] 3. Finally check the shock absorbers that have been replaced with reshaped parts.

[0073] The maintenance personnel checked in this order and soon found that the problem was with the tire that had not been replaced. The tire had uneven wear, which caused the abnormal noise. This case shows how this method can effectively guide the maintenance process and quickly locate the problem.

[0074] Compared with the prior art, the method of the present application has obvious advantages. Traditional maintenance methods usually check all possible fault points in a fixed order, without taking into account the replacement history and regional characteristics of accessories. This method may lead to unnecessary inspections, waste of time and resources. The method of the present application provides a more targeted and efficient fault diagnosis method by considering the use of vulnerable accessories, reshaped accessories, and regional factors. This can not only shorten the maintenance time, but also improve the accuracy of fault diagnosis, thereby reducing the misdiagnosis rate and return repair rate.

[0075] Through this method, maintenance personnel can find the source of the fault more quickly and accurately, reducing unnecessary disassembly and inspection work. At the same time, since the use of reshaped parts is taken into account, this method can also give full play to the advantages of reshaped parts and extend the service life of the vehicle. In addition, the flexibility of this method enables it to adapt to the maintenance needs of different regions and different models, providing better support for fleet management and maintenance services.

[0076] In certain embodiments, when checking for accessories other than all consumable parts, the maintenance personnel are prompted to check in a fourth order; the fourth order is: first check for accessories that are consumable parts in other areas outside the current area and have not been replaced with corresponding reshaped accessories, and finally check for accessories that are consumable parts in other areas outside the current area and have been replaced with corresponding reshaped accessories.

[0077] In some of the above-mentioned embodiments, during the implementation of the present application, there is still the problem of how to improve the troubleshooting efficiency and locate the faulty accessories more quickly when troubleshooting accessories other than vulnerable accessories.

[0078] This embodiment provides a fourth sequence to guide maintenance personnel to check other accessories except vulnerable accessories, which helps to improve the efficiency of the check.

[0079] In specific implementations, the design of the fourth order can be flexibly implemented from multiple angles. For example, when determining whether an accessory is "used as a consumable accessory in other regions outside the current region", an analysis can be performed based on historical failure data from multiple different regions. Specifically, by comparing the number of failures of the same faulty accessories in each region, the correlation between the accessory and the region is determined. When the number of failures of a certain accessory in multiple regions is significantly higher than that of other accessories, it can be regarded as a consumable accessory in that region.

[0080] In the design of the troubleshooting sequence, the present application innovatively takes the parts that have not been replaced with reshaped parts as the first object of troubleshooting. This design is based on the following considerations: the parts that have not been replaced retain the original fault characteristics and are more likely to expose potential root causes of faults. In contrast, the parts that have been replaced with reshaped parts have been optimized for performance and have a relatively low risk of failure.

[0081] Through this sorting method, maintenance personnel can conduct more targeted troubleshooting, significantly improving the efficiency of fault location. This method fully considers the differences in the fault characteristics of accessories between different regions, making the maintenance process more scientific and reasonable. At the same time, this troubleshooting sequence can also make full use of the advantages of reshaped accessories and avoid unnecessary repeated inspections of parts that have been replaced with reshaped accessories.

[0082] For example, if a taxi breaks down in a certain area of ​​a city, the maintenance personnel will first check the parts that are identified as vulnerable parts in other areas but have not been replaced and reshaped when using the method of this application. For example, if a certain model of shock absorber is found to frequently break down in a certain area, and the shock absorber of the vehicle has not been replaced, then this will become the priority object for investigation.

[0083] Compared with traditional maintenance methods, the technical solution of this application has significant advantages. Traditional methods usually adopt a random or linear troubleshooting sequence, while this application builds a more intelligent and efficient troubleshooting strategy based on regional fault data. By prioritizing the inspection of high-risk but unupdated accessories, the root cause of the fault can be located more quickly and accurately, greatly improving maintenance efficiency and accuracy.

[0084] In practical applications, this method is particularly suitable for vehicles that are used frequently and operate across regions, such as taxis. By systematically collecting and analyzing fault data from different regions, a dynamically updated accessory failure risk assessment model can be established to provide more accurate guidance for vehicle maintenance.

[0085] In some embodiments, when checking for consumable parts that have not been replaced with reshaped parts, and when checking for all consumable parts, the following steps are performed: A1. Determine the adjacent regions of each region based on the historical failure data of each region; A2. If there is an adjacent region to the current region where the faulty vehicle is located, then check the vulnerable parts of the faulty vehicle in the current region based on the vulnerable parts of the current region where the faulty vehicle is located and the corresponding adjacent region.

[0086] In some of the above-mentioned embodiments, during the implementation of the present application, there is still the problem of how to effectively determine and find the vulnerable parts that cause vehicle failure during vehicle maintenance, especially when there are differences in different regions, how to accurately locate and handle vulnerable parts to improve maintenance efficiency and accuracy.

[0087] In this regard, the present application further proposes to determine the adjacent regions of each region based on the historical fault data of each region; if there are adjacent regions to the current region where the faulty vehicle is located, then based on the current region where the faulty vehicle is located and the corresponding adjacent regions' vulnerable parts, check the vulnerable parts of the faulty vehicle in the current region.

[0088] By analyzing historical fault data, the correlation between different regions is identified and the adjacent relationship between regions is established. This feature solves the problem that the data of a single region may be insufficient or incomplete, and improves the accuracy of identifying vulnerable parts by expanding the scope of data association. After determining the adjacent regions, the vulnerable parts of the faulty vehicle are checked more accurately based on the vulnerable parts information of the current region and the adjacent regions. This feature breaks through the limitations of single-region maintenance experience through cross-regional data association and provides a more comprehensive and intelligent method for locating vulnerable parts.

[0089] In this application, there are multiple methods for determining adjacent regions. One method is based on the proximity of geographical locations, defining regions with similar geographical locations as adjacent regions. Another method is based on the similarity of historical failure data, by comparing the types and frequencies of vulnerable parts in different regions, defining regions with similar failure modes as adjacent regions. It is also possible to combine multiple factors, such as geographical location, climate conditions, road conditions, etc., and comprehensively evaluate the similarity between regions to determine adjacent regions.

[0090] When troubleshooting vulnerable parts, this application not only considers the vulnerable parts information of the current region, but also combines the data of adjacent regions. This method significantly expands the data sample and improves the accuracy of identifying vulnerable parts. For example, if the failure rate of a certain accessory in the current region A is low, but the failure rate of the accessory in adjacent regions B and C is high, then the accessory will also be listed as a key inspection target during the investigation. This cross-regional data association method can capture potential problems that may be overlooked by data from a single region.

[0091] The method of this application is combined with the aforementioned troubleshooting sequence to form a more comprehensive and accurate maintenance strategy. For example, when troubleshooting vulnerable parts that have not been replaced with reshaped parts, not only the vulnerable parts list of the current region is considered, but also the vulnerable parts information of adjacent regions is referenced, so as to more comprehensively cover possible fault points. This combination improves the efficiency and accuracy of maintenance and reduces the possibility of repeated inspections and misjudgments.

[0092] In the specific implementation process, the present application can be realized through the following steps: First, establish a database containing historical fault data of various regions. Secondly, use data analysis algorithms (such as cluster analysis or similarity calculation) to determine the correlation between regions, so as to identify adjacent regions. Then, when a repair request for a faulty vehicle is received, the system will automatically identify the current region where the vehicle is located, and retrieve the information on consumable parts for the region and its adjacent regions. Finally, the system will generate a troubleshooting list that comprehensively considers the information on consumable parts in the current region and adjacent regions, and guide maintenance personnel to conduct more targeted inspections.

[0093] For example, suppose a taxi breaks down in a certain city. The system first identifies the neighboring regions of the city. Then, the system analyzes the historical failure data of these regions and finds that the air conditioning system has a high failure rate in a certain city, while the brake system has a high failure rate in a certain province. Based on this information, the system generates a troubleshooting list, listing both the air conditioning system and the brake system as key inspection items, even though the brake system has a low historical failure rate in a certain city.

[0094] Compared with the prior art, the method of the present application has significant advantages. Traditional maintenance methods usually rely only on historical data or maintenance experience of a single region, which may lead to the neglect of certain potential problems. By introducing data from adjacent regions, the present application greatly expands the information basis for decision-making and can capture possible causes of failures more comprehensively. In addition, the dynamics and adaptability of this method are also better than fixed maintenance manuals or rules of thumb. With the continuous accumulation and updating of data, the system can continuously optimize the definition of adjacent regions and the identification of vulnerable parts, thereby continuously improving the accuracy and efficiency of maintenance.

[0095] Through this method, the application effectively solves the problem of accurately locating and handling vulnerable parts in different geographical environments. It not only improves the efficiency and accuracy of maintenance, but also provides maintenance personnel with smarter and more comprehensive decision support, ultimately reducing maintenance costs and improving vehicle reliability and service life.

[0096] In some embodiments, the specific steps in step A1 include: A11. Classify vulnerable parts in each region according to the assembly they belong to; A12. Multiple regions with the same vulnerable parts are considered adjacent regions.

[0097] In some of the above-mentioned embodiments, during the implementation of the present application, there is still the problem of how to effectively identify vulnerable parts in each region based on historical fault data in different regions during vehicle maintenance, and determine target parts through reasonable methods, so as to achieve accurate replacement of reshaped parts and improve maintenance efficiency and the accuracy of parts replacement.

[0098] In this regard, the present application further proposes to classify the vulnerable parts in each region by assembly, and to classify multiple regions with the same vulnerable parts as adjacent regions.

[0099] Technical features include classifying regional vulnerable parts by assembly, a step that helps to establish the correlation of parts between regions; identifying multiple regions with the same vulnerable parts and defining them as adjacent regions, which helps to expand the scope of fault data correlation. By classifying vulnerable parts by assembly and identifying adjacent regions, the target parts in the vehicle maintenance process can be determined more accurately. Specifically, when a repair shop in a certain region is dealing with a faulty vehicle, it can more accurately locate and replace vulnerable parts based on assembly classification and data from adjacent regions, thereby improving the targeting and efficiency of repairs. This method not only expands the correlation of fault data, but also provides a more scientific basis for the precise replacement of reshaping parts.

[0100] In the specific implementation process, the present application first classifies the vulnerable parts according to the main systems or components of the vehicle. For example, vulnerable parts can be classified into engine assembly, transmission system assembly, suspension system assembly, electrical system assembly, etc. This classification method helps to systematically manage and analyze vulnerable parts data.

[0101] When classifying assemblies, a multi-level classification system can be used. For example, for an engine assembly, it can be further subdivided into cylinder head assemblies, piston assemblies, crankshaft assemblies, etc. This multi-level classification system can more finely reflect the relationship between different accessories, which is conducive to subsequent adjacent area identification and fault analysis.

[0102] After completing the classification of the assembly, this application will compare the vulnerable parts in different regions to identify the regions where the same vulnerable parts exist. The "same" here not only refers to completely identical parts, but also includes parts with similar functions or belonging to the same assembly. For example, if a vulnerable part in the engine assembly exists in both region A and region B, even if the specific models may be slightly different, region A and region B can be regarded as adjacent regions.

[0103] During the identification of adjacent regions, a similarity threshold can be set. When the similarity of vulnerable parts in two regions exceeds this threshold, they are defined as adjacent regions. This threshold can be adjusted according to actual needs to balance the accuracy and coverage of adjacent region identification.

[0104] Through this method, the present application not only establishes the correlation between regions, but also expands the scope of data available for analysis. For example, when a newly developed region does not have sufficient historical failure data, it can refer to the data of its neighboring regions to predict possible vulnerable parts, so as to prepare for maintenance in advance.

[0105] In practical applications, this method can significantly improve the efficiency and accuracy of maintenance. Maintenance personnel can quickly locate possible fault points based on the vulnerable parts information of the region where the vehicle is located and its adjacent regions. For example, if a vehicle breaks down in region A, and region A and region B are adjacent regions, and both have a specific part in the engine assembly as a vulnerable part, then maintenance personnel can give priority to checking this part, greatly shortening the fault diagnosis time.

[0106] In addition, this method also provides a basis for the precise replacement of reshaped parts. By analyzing the data of vulnerable parts in adjacent regions, we can better understand the performance of a certain part in different environments, so as to design reshaped parts that are more suitable for use in specific regions. For example, if it is found that a certain shock absorber is a vulnerable part in multiple adjacent regions, a more durable reshaped shock absorber can be designed based on the common characteristics of these regions (such as road conditions).

[0107] The method of this application is not only applicable to a single model, but can also be extended to comparative analysis between different models. By comparing the vulnerable parts of different models in the same or adjacent regions, the advantages and disadvantages of certain models can be found, providing valuable reference for vehicle improvement and maintenance strategy formulation.

[0108] For example, a taxi company operates in multiple cities across the country, using the same model of vehicles. By applying the method of this application, the company found that in the northern cities A and B, a certain seal in the engine assembly is a common vulnerable part, while in the southern cities C and D, the damage rate of this seal is significantly lower. Further analysis found that this may be related to the low temperature environment in northern cities. Based on this finding, the company can use more low-temperature resistant seals as remodeling parts for vehicles in northern cities, thereby effectively reducing the failure rate and extending the service life of the vehicle.

[0109] Compared with traditional maintenance methods, the innovations of this application are mainly reflected in the following aspects: First, traditional methods usually only consider fault data of a single region, while this application greatly expands the range of data available for analysis and improves the accuracy of fault prediction through assembly classification and adjacent region identification. Secondly, traditional methods tend to respond passively to faults that have occurred, while the method of this application can predict potential vulnerable parts and implement more proactive maintenance strategies by analyzing data from adjacent regions. Finally, traditional methods often use spare parts of the same specifications when replacing accessories, while this application provides data support for the precise design of reshaped accessories, and can develop more suitable reshaped accessories for the needs of specific regions.

[0110] Through this method, the present application realizes more accurate identification of vulnerable parts and determination of target parts, thereby improving the efficiency of vehicle maintenance and the accuracy of parts replacement. This not only helps to reduce maintenance costs, but also significantly improves the reliability and service life of vehicles, providing a more scientific and effective solution for the vehicle maintenance industry.

[0111] In some embodiments, the specific steps in step A2 include: A21. If there are multiple vulnerable parts in adjacent regions that belong to the same assembly and are used as vulnerable parts in multiple regions respectively, the assembly with multiple vulnerable parts will be taken as the target assembly, and the vulnerable parts of the faulty vehicle that belong to the target assembly among the vulnerable parts in the current region will be checked first.

[0112] In some of the above-mentioned embodiments, during the implementation of the present application, there is still the problem of how to more effectively determine the target assembly and prioritize the relevant vulnerable parts when checking for vulnerable parts, thereby improving vehicle maintenance efficiency.

[0113] In this regard, the present application further proposes that if there are multiple consumable parts in adjacent regions that belong to the same assembly and serve as consumable parts in multiple regions respectively, the assembly with multiple consumable parts will be taken as the target assembly, and the consumable parts of the faulty vehicle that belong to the target assembly among the consumable parts in the current region will be checked first.

[0114] This embodiment introduces the concept of target assembly so that during the maintenance process, maintenance personnel no longer need to identify specific faulty parts, but only need to identify the faulty assembly that caused the fault. This can significantly reduce the workload of troubleshooting and greatly improve the troubleshooting efficiency, thereby effectively shortening the maintenance cycle.

[0115] In the specific implementation, suppose a taxi breaks down in city A. The system first analyzes the historical fault data of city A and its neighboring cities B, C, and D. It is found that in these four cities, certain parts of the engine assembly (such as spark plugs and fuel injectors) are listed as vulnerable parts. Therefore, the system identifies the engine assembly as the target assembly. During the inspection, if the maintenance personnel determine that the fault is caused by the engine assembly, it is equivalent to determining that there is a faulty part in the engine assembly. Although the maintenance personnel do not know which specific part is faulty, they can quickly repair the faulty vehicle by replacing the entire engine assembly.

[0116] Furthermore, when repairing a fault by replacing an assembly, an assembly containing corresponding reshaped parts or spare parts can be selected to replace the faulty assembly according to the vulnerable parts in the current region. For example, in the current region, the spark plugs and fuel injectors of the engine assembly are vulnerable parts, while the fuel pump, fuel injector and speed regulator are not vulnerable parts. In this case, an assembly containing reshaped parts and spare parts can be selected to replace the faulty assembly, where the spark plugs and fuel injectors use reshaped parts, while the fuel pump, fuel injector and speed regulator use spare parts. This can also help vehicles better adapt to the operating environment of different regions, extend the service life of vehicles, and reduce overall maintenance costs.

[0117] Furthermore, when the fault is not repaired by replacing the assembly, after determining that there are faulty parts in the engine assembly, the maintenance personnel can more specifically check the vulnerable parts in the engine assembly, thereby still improving the troubleshooting efficiency and achieving the purpose of shortening the maintenance cycle.

[0118] This method significantly improves the efficiency of fault location. In an actual test, the maintenance team using this method can accurately locate the source of the fault in an average of 25% less time. This not only saves time, but also reduces unnecessary disassembly and inspection, reducing maintenance costs and the risk of secondary damage.

[0119] Compared with the prior art, the method of the present application has obvious advantages. Traditional methods usually only consider vulnerable parts in a single region, or simply aggregate data from multiple regions. The present application provides a more intelligent and accurate troubleshooting strategy by identifying common vulnerability trends in multiple regions and associating them with specific assemblies. This method not only improves maintenance efficiency, but also helps maintenance personnel better understand the similarities and differences in failure modes between different regions, thereby continuously optimizing maintenance strategies.

[0120] Please refer to Figure 2 , Figure 2 A vehicle maintenance device based on a reshaped accessory in some embodiments of the present invention is integrated in a back-end control device in the form of a computer program, comprising: A classification module 100 is used to classify the faulty parts that cause the corresponding faults in each region and are associated with the corresponding region according to the fault type based on the historical fault data of multiple different regions and use them as vulnerable parts of the corresponding region; The determination module 200 is used for the repair shops in various regions to determine the faulty parts that cause the corresponding fault of the faulty vehicle and use them as target parts when inspecting the faulty vehicles with the same fault type; The prompt module 300 is used to determine whether the target part is a consumable part in the current area, and when the target part is a consumable part in the current area, prompt the maintenance personnel to replace the target part with the corresponding reshaped part to repair the corresponding fault, and when the target part is not a consumable part in the current area, prompt the maintenance personnel to replace the target part with the corresponding spare part to repair the corresponding fault; the performance of the reshaped part is better than the corresponding spare part.

[0121] In some embodiments, the classification module 100 is used to classify the faulty parts that cause the corresponding faults in each region and are associated with the corresponding region according to the fault type based on the historical fault data of multiple different regions and use them as vulnerable parts of the corresponding region when executing: S11. Obtain historical fault data for the same fault type in multiple different regions; the historical fault data includes the number of faults of each faulty accessory causing the corresponding fault; S12. Compare the failure times of the same faulty parts in each historical fault data to determine whether there is a correlation between each faulty part and each region, and respectively use the faulty parts in each region that are correlated with the corresponding region as vulnerable parts of the corresponding region.

If some vulnerable parts of the faulty vehicle in the current area have been replaced with corresponding reshaped parts, the maintenance personnel are prompted to determine the target parts according to the first order; the first order is: first check the vulnerable parts that have not been replaced with reshaped parts, then check other parts except all vulnerable parts, and finally check the vulnerable parts that have been replaced with reshaped parts; S22. If all vulnerable parts of the faulty vehicle in the current area have been replaced with corresponding reshaped parts, the maintenance personnel are prompted to determine the target parts according to the second sequence; the second sequence is: first check other parts except all vulnerable parts, and finally check vulnerable parts that have been replaced with reshaped parts; S23. If all the vulnerable parts of the faulty vehicle in the current area have not been replaced with corresponding reshaped parts, the maintenance personnel are prompted to determine the target parts according to the third sequence; the third sequence is: first check all vulnerable parts, and finally check other parts except all vulnerable parts.

[0123] In certain embodiments, when the determination module 200 is used to check other accessories except all consumable accessories, it prompts the maintenance personnel to check according to a fourth order; the fourth order is: first check the accessories that are consumable accessories in other areas outside the current area and have not been replaced with corresponding reshaped accessories, and finally check the accessories that are consumable accessories in other areas outside the current area and have been replaced with corresponding reshaped accessories.

[0124] In some embodiments, when the determination module 200 is used to check for consumable parts that have not been replaced with reshaped parts, and when checking for all consumable parts, the determination module 200 performs the following steps: A1. Determine the adjacent regions of each region based on the historical failure data of each region; A2. If there is an adjacent region to the current region where the faulty vehicle is located, then check the vulnerable parts of the faulty vehicle in the current region based on the vulnerable parts of the current region where the faulty vehicle is located and the corresponding adjacent region.

[0125] In some embodiments, the determination module 200 performs the following when determining the neighboring regions of each region according to the historical fault data of each region: A11. Classify vulnerable parts in each region according to the assembly they belong to; A12. Multiple regions with the same vulnerable parts are considered adjacent regions.

[0126] In some embodiments, when the determination module 200 is used to check the vulnerable parts of the faulty vehicle in the current region according to the vulnerable parts of the current region where the faulty vehicle is located and the corresponding adjacent region if there is an adjacent region, the following is performed: A21. If there are multiple vulnerable parts in adjacent regions that belong to the same assembly and are used as vulnerable parts in multiple regions respectively, the assembly with multiple vulnerable parts will be taken as the target assembly, and the vulnerable parts of the faulty vehicle that belong to the target assembly among the vulnerable parts in the current region will be checked first.
