Description

Technical Field

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

[0002] In real life, when a vehicle breaks down while driving, the owner can often only move the vehicle to a repair shop for repair. However, for most failures, the problem can often be solved by simply replacing the faulty assembly with a new one. The replacement can even be completed on-site (where the vehicle is located) to quickly resolve the problem. However, because the owner does not understand the situation or there are no replaceable spare assemblies and available equipment on site, the owner has to spend a lot of time going to the repair shop, which causes great inconvenience to the owner.

[0003] There is currently no effective technical solution to the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle fault repair method, a vehicle fault repair system and related equipment, which solves the problem that some vehicle faults can be solved on the spot but require users to spend a lot of time going to a repair shop for repair, which can greatly facilitate users and help improve the user experience in terms of repair services.

[0005] In a first aspect, the present invention provides a vehicle fault repair method, which is applied to a server of a vehicle fault repair system, wherein the vehicle fault repair system further includes a user terminal, a repair terminal and a mobile terminal; the vehicle fault repair method includes the following steps: S1. After all faulty assemblies causing the fault are determined by the user terminal, the types of all the faulty assemblies are determined; the types include easily disassembled and non-easy disassembled types; S2. When all the faulty assemblies are of the easily dismantled type, a dispatch instruction is generated and sent to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or a first notification message is generated and sent to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly; S3. When the type of any of the faulty assemblies is non-dismantlable, generate a second notification message and send the second notification message to the user terminal so that the user can go to the location of the maintenance end and repair the faulty assembly.

[0006] The vehicle fault repair method provided by the present invention adopts the on-site repair method of the mobile terminal actively dispatched by the maintenance service provider for minor faults (i.e., faults that can be solved on site by replacing the assembly), thereby reducing the time spent by users due to the fault, facilitating users and greatly improving the user experience.

[0007] Furthermore, the specific steps in step S1 include: S11. Based on a preset database, an assembly having a continuous assembly relationship with the faulty assembly is obtained as an associated assembly; the continuous assembly relationship means that the faulty assembly has a unique assembly sequence and disassembly sequence with all the associated assemblies; S12. Determine the assembly type of the faulty assembly according to the disassembly sequence.

[0008] The present invention uses a systematic and digitized method, combined with the actual structure and assembly relationship of the vehicle, to more objectively and accurately evaluate the feasibility of maintenance.

[0009] Furthermore, the specific steps in step S12 include: S121. When the faulty assembly is the first assembly to be disassembled in the disassembly sequence and all equipment required for disassembling the faulty assembly can be carried by the mobile terminal, the type of the faulty assembly is classified as easy to disassemble; S122. When the faulty assembly is the first assembly to be disassembled in the disassembly sequence and any equipment required to disassemble the faulty assembly cannot be carried by the mobile terminal, the type of the faulty assembly is classified as non-easy to disassemble; S123. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, perform the following steps: S1231. According to the disassembly sequence, all assemblies that must be disassembled before disassembling the faulty assembly are obtained and used as the assemblies that must be disassembled; S1232. When all equipment required for disassembling the faulty assembly and all the necessary disassembly assemblies can be carried by the mobile terminal, the type of the faulty assembly is classified as easy to disassemble; S1233. When any equipment required to disassemble the faulty assembly and all the necessary-to-disassemble assemblies cannot be carried by the mobile terminal, the type of the faulty assembly is classified as non-easy-to-disassemble.

[0010] The present invention can provide on-site maintenance services under appropriate circumstances by accurately determining the type of faulty assembly, thereby greatly improving maintenance efficiency. At the same time, this method can also optimize the allocation of maintenance resources, avoid simple faults occupying the resources of the maintenance shop, and thus improve the overall maintenance efficiency.

[0011] Furthermore, the specific steps in step S2 include: S2A1. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, all equipment required to disassemble the faulty assembly and all the necessary assemblies are arranged in the disassembly sequence and an equipment layout list is generated; S2A2. When the dispatch instruction is sent to the mobile terminal, the equipment layout list is sent to the mobile terminal so that the relevant personnel of the mobile terminal can place all the devices used to dismantle the faulty assembly and all the assemblies that must be dismantled in an orderly manner on the mobile terminal according to the sequence on the equipment layout list.

[0012] The method of the present invention ensures that all necessary tools are ready in the correct order through a systematic equipment arrangement list, thereby significantly improving maintenance efficiency and reducing the risk of operating errors.

[0013] Furthermore, the specific steps in step S2 include: S2B1. When a plurality of the faulty assemblies are mutually associated assemblies, all spare assemblies for replacing the faulty assemblies are arranged in the assembly order and an assembly layout list is generated; S2B2. When the dispatch instruction is sent to the mobile terminal, the assembly arrangement list is sent to the mobile terminal so that the relevant personnel of the mobile terminal can place all the spare assemblies in order on the mobile terminal according to the sequence on the assembly arrangement list and replace all the faulty assemblies in order.

[0014] In a second aspect, the present invention provides a vehicle fault maintenance system, comprising a user terminal, a server, a maintenance terminal and a mobile terminal; the user terminal is used to determine all fault assemblies causing the fault through a preset intelligent question-answering model and feed back to the server; The server is used to perform the following steps: S1. After all faulty assemblies causing the fault are determined by the user terminal, the types of all the faulty assemblies are determined; the types include easily disassembled and non-easy disassembled types; S2. When all the faulty assemblies are of the easily dismantled type, a dispatch instruction is generated and sent to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or a first notification message is generated and sent to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly; S3. When the type of any of the faulty assemblies is non-dismantlable, generate a second notification message and send the second notification message to the user terminal so that the user can go to the location of the maintenance end and repair the faulty assembly.

[0015] Furthermore, it also includes a factory end, which is used to receive the faulty assembly from the maintenance end and the mobile end and repair the faulty assembly.

[0016] In a third aspect, the present invention provides a vehicle fault repair device, which is applied to a server of a vehicle fault repair system, wherein the vehicle fault repair system further includes a user terminal, a repair terminal and a mobile terminal; the vehicle fault repair device includes: A judgment module, configured to judge the types of all the faulty assemblies after determining all the faulty assemblies causing the fault through the user terminal; the types include easily disassembled and non-easy disassembled types; A first control module is used for generating a dispatch instruction and sending the dispatch instruction to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or generating a first notification message and sending the first notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly when all the faulty assemblies are of the easily dismantled type; The second control module is used to generate a second notification message and send the second notification message to the user terminal when the type of any of the faulty assemblies is non-dismantlable, so as to enable the user to go to the location of the maintenance end and repair the faulty assembly.

[0017] The vehicle fault repair device provided by the present invention provides door-to-door repair options for easily dismantled faults by judging the fault type, thereby greatly improving the repair efficiency. At the same time, for complex non-easy-to-dismantle faults, the user is directly guided to the appropriate repair terminal, avoiding unnecessary attempts and delays. This differentiated processing method not only improves the overall repair efficiency, but also optimizes resource allocation and improves user experience.

[0018] In a fourth 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 in the vehicle fault repair method provided in the first aspect are executed.

[0019] In a fifth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, runs the steps of the vehicle fault repair method provided in the first aspect above.

[0020] From the above, it can be seen that the vehicle fault repair method provided by the present invention is based on a vehicle fault repair system including a maintenance end as a fixed repair shop and a mobile end as a mobile repair shop. Different repair methods are provided to users according to the type of faulty assembly. In this way, when users face minor faults, they only need to wait for the mobile repair shop to come to the door for repair and no longer need to take the initiative to go to the fixed repair shop. This achieves the effect of quickly resolving the fault on the spot, greatly facilitating users and greatly improving the user experience.

[0021] 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 breakdown repair, the current repair process has problems of inefficiency and waste of resources. When a vehicle breaks down, the owner usually needs to move the vehicle to a repair shop for inspection. This method is unnecessary for many simple faults. In fact, most faults can be solved by simply replacing the corresponding faulty assembly, or even repairs can be completed directly at the location of the vehicle. However, due to the lack of professional knowledge of the car owner, it is impossible to judge the severity of the fault and the complexity of the repair, and there is a lack of replaceable spare assemblies and repair tools on site, which causes the car owner to send the vehicle to the repair shop, which not only increases the time cost of the car owner, but also causes an unreasonable allocation of maintenance resources.

[0030] Specifically, suppose an electric car suddenly has a powertrain failure while driving on the highway. The on-board diagnostic system shows that there may be a problem with the motor controller, but the owner cannot determine whether this is a part that can be quickly replaced on site. Under the current maintenance model, the owner can only choose to tow the vehicle to the nearest repair shop. However, if the motor controller is a part that is easy to disassemble and replace, it is entirely possible to have a mobile repair shop (such as a repair truck that can provide door-to-door repair services) carry spare parts to the site for replacement, which can greatly shorten the vehicle fault repair time and reduce the impact on the owner's travel. However, due to the lack of effective fault classification and corresponding maintenance strategies, this efficient maintenance method is difficult to achieve today.

[0031] Furthermore, if this problem cannot be effectively solved, it will lead to a serious waste of maintenance resources and a decline in customer satisfaction. For simple faults, vehicles are sent to repair shops unnecessarily, which will occupy limited maintenance resources and prolong the waiting time for other vehicles that need professional repairs. At the same time, the dissatisfaction of car owners caused by long waits for repairs may affect the brand reputation. From a technical perspective, the lack of intelligent fault classification and maintenance scheduling systems makes it impossible to optimize the maintenance process according to the fault type, which not only reduces the overall maintenance efficiency, but also increases the maintenance cost.

[0032] In this regard, the present invention provides a vehicle fault repair method, which is applied to a server of a vehicle fault repair system, wherein the vehicle fault repair system further includes a user terminal, a repair terminal and a mobile terminal; the vehicle fault repair method includes the following steps: S1. After all faulty assemblies causing the fault are determined through the user terminal, the types of all faulty assemblies are determined; the types include easily disassembled and non-easy disassembled types; S2. When all faulty assemblies are of the easily disassembled type, a dispatch instruction is generated and sent to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or a first notification message is generated and sent to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly; S3. When the type of any faulty assembly is non-dismantlable, generate a second notification message and send the second notification message to the user terminal so that the user can go to the location of the maintenance terminal and repair the faulty assembly.

[0033] First of all, consider the diversity and complexity of vehicle failures. Some failures may require professional equipment and environment to repair, while some failures can be solved by simple component replacement. This raises a question: how to distinguish these different types of failures and formulate corresponding maintenance strategies for them. Based on this idea, this embodiment proposes the idea of ​​dividing the fault assembly into easy-to-disassemble and non-easy-to-disassemble types. Easy-to-disassemble failures refer to those that can be solved on-site by replacing the fault assembly, while non-easy-to-disassemble failures require more complex maintenance processes to solve. This classification method provides a basis for the formulation of subsequent maintenance strategies.

[0034] Next, consider how to optimize the maintenance process based on the type of fault. For easily disassembled faults, door-to-door service can save the owner's time. For non-easy-to-disassemble faults, directly guide the owner to a professional repair point. These considerations prompted the design of an intelligent vehicle fault maintenance system.

[0035] In this system, the user terminal, server, maintenance terminal and mobile terminal are four key components. The user terminal is used for preliminary diagnosis and fault reporting, the server is responsible for analyzing the fault type and formulating maintenance strategies, the maintenance terminal is a professional maintenance point, and the mobile terminal is a mobile repair shop that can provide door-to-door service.

[0036] Overall, the method of the present invention achieves optimal allocation of maintenance resources through intelligent fault classification and maintenance strategy selection. It not only improves maintenance efficiency and reduces the waiting time of car owners, but also expands the coverage and flexibility of maintenance services by introducing mobile repair shops. This systematic fault judgment and maintenance process effectively improves the accuracy and efficiency of maintenance, and ultimately achieves the goal of providing more efficient and convenient maintenance services and reducing unnecessary time and energy waste for car owners.

[0037] Specifically, for example, an electric car suddenly experiences a power system failure while driving on a highway. The on-board diagnostic system reports the possible faulty assembly to the server through the user terminal, namely the motor controller. After receiving this information, the server immediately queries the preset database to determine the type of motor controller. According to the information in the database, the motor controller is classified as an easily disassembled assembly because it is usually located in an easily accessible position and the tools required for replacement are relatively simple.

[0038] Based on this judgment, the server generates a dispatch instruction and sends it to the nearest mobile repair shop. The mobile repair shop is equipped with professional tools and common spare parts for electric vehicles, including motor controllers. After receiving the dispatch instruction, the mobile repair shop quickly locates the faulty vehicle through the navigation system.

[0039] When the maintenance personnel arrive at the scene, they first conduct a safety check to ensure that the vehicle is in a power-off state. Then, according to standard operating procedures, they remove the vehicle shell and access the motor controller. Special tools are used to remove the faulty motor controller and replace it with a new one. The whole process takes about 30 minutes. After the replacement is completed, the maintenance personnel conduct a system test to confirm that the fault has been eliminated and the vehicle has resumed normal operation.

[0040] This on-site rapid repair method greatly reduces the waiting time and inconvenience of the car owner. Compared with the traditional method of towing the vehicle to a repair shop, which may take hours or even days, the method of the present invention only takes about 1 hour to solve the problem, greatly improving the repair efficiency.

[0041] Another example is a hybrid car reporting an engine failure. The user submits the failure information to the server through a smartphone APP (user terminal). After analysis, the server determines that the possible faulty assemblies include the fuel injection system and the turbocharger. After querying the database, the server finds that the fuel injection system is easily disassembled, while the turbocharger is not easily disassembled.

[0042] Due to the existence of non-dismantled faulty assemblies, the server generated a second notification message and pushed it to the user through the APP, suggesting that the user send the vehicle to the nearest professional maintenance point. At the same time, the server also provides the user with the location, contact information and current busy and idle status of the three nearest maintenance points, and provides an online appointment function. The user selects the nearest maintenance point and completes the appointment. After receiving the appointment information, the maintenance point immediately begins to prepare the required testing equipment and possible spare parts. When the vehicle arrives, the maintenance personnel are fully prepared and can quickly carry out fault diagnosis and repair work.

[0043] This method avoids unnecessary on-site repair attempts and saves the resources of the mobile repair shop. At the same time, by making appointments and preparing in advance, it reduces the waiting time of users at the repair point and improves the overall repair efficiency.

[0044] The solution of the present invention has significant advantages over the prior art. The traditional vehicle fault repair process is usually to send the vehicle to the repair shop uniformly, regardless of the complexity of the fault. This method is often inefficient for simple faults and causes waste of resources. In contrast, the present invention achieves differentiated treatment of repair methods by intelligently judging the type of faulty assembly. For easily disassembled faults, on-site repair services are provided, which greatly shortens the repair time and improves user satisfaction. For complex faults, users are directly guided to professional repair points to avoid unnecessary attempts and delays.

[0045] In addition, the present invention introduces the concept of a mobile repair shop, which greatly expands the coverage of repair services. This not only improves the efficiency of repairs, but also enhances the ability to respond to emergencies. For example, for easily dismantled faults occurring in remote areas, mobile repair shops can respond quickly, avoiding the extra cost and time loss caused by long-distance towing.

[0046] In general, the vehicle fault repair method provided by the present invention effectively solves the problems of inefficiency and waste of resources in the traditional repair mode through technological innovation, provides users with more convenient and efficient repair services, and also provides a more optimized resource allocation solution for repair service providers.

[0047] In some embodiments, the specific steps in step S1 include: S11. Based on a preset database, an assembly having a continuous assembly relationship with the faulty assembly is obtained and used as an associated assembly; the continuous assembly relationship means that the faulty assembly has a unique assembly sequence and disassembly sequence with all associated assemblies; S12. Determine the assembly type of the faulty assembly based on the disassembly sequence.

[0048] This embodiment provides a more reliable basis for judging the type of faulty assembly by introducing the concepts of associated assembly and continuous assembly relationship. Specifically: the use of the preset database ensures the accuracy and completeness of the associated assembly information. The definition of the continuous assembly relationship clarifies the unique disassembly and assembly sequence between the faulty assembly and the associated assembly, providing a basis for subsequent judgment. The method of judging the type of assembly according to the disassembly sequence takes into account the operation sequence in the actual maintenance process, so that the judgment result is more in line with the actual situation. This method can more accurately judge whether the faulty assembly belongs to the easy-to-disassemble category or the non-easy-to-disassemble category by analyzing the position and disassembly difficulty of the faulty assembly in the entire assembly system. Compared with judging by experience or simple rules alone, this method takes into account more practical factors and improves the accuracy and reliability of the judgment. By accurately judging the type of the faulty assembly, the system can arrange subsequent maintenance methods more reasonably, such as deciding whether to dispatch a mobile terminal for on-site maintenance or notify the user to go to the maintenance terminal for maintenance. This not only improves maintenance efficiency, but also optimizes resource allocation and improves user experience.

[0049] When implementing the preset database, multiple methods can be used. For example, a relational database such as MySQL can be used, or a non-relational database such as MongoDB can be used. The database can store data such as vehicle model, assembly information, and assembly relationship. The continuous assembly relationship can be represented by a directed graph structure, where each node represents an assembly and the edge represents the assembly order. This structure can quickly query the assembly relationship between any two assemblies.

[0050] The process of obtaining the associated assemblies can be implemented by a depth-first search or a breadth-first search algorithm. Starting from the faulty assembly, search in both the upward and downward directions along the assembly relationship until all related assemblies are found. This method ensures that all assemblies that have a direct or indirect assembly relationship with the faulty assembly are found.

[0051] In the process of judging the type of assembly, the concept of difficulty coefficient can be introduced. For example, there are 9 associated assemblies that have a continuous assembly relationship with the faulty assembly, and the faulty assembly ranks third in the disassembly order (that is, two associated assemblies must be disassembled before the faulty assembly can be disassembled). A basic difficulty coefficient is set for each assembly (for example, the range is 1-10, and the basic difficulty coefficient is affected by factors such as the weight or volume of the equipment required for disassembly. For example, the basic difficulty coefficient of an assembly that can be disassembled using a screwdriver or a wrench is 1, the basic difficulty coefficient of an assembly that requires a jack is 1.5, and the basic difficulty coefficient of an assembly that requires a lift is 8, etc.). Assume that the basic difficulty coefficient of the first associated assembly to be disassembled is 1. The basic difficulty coefficient is 1, the basic difficulty coefficient of the second associated assembly to be disassembled is 8, and the basic difficulty coefficient of the faulty assembly is 1.5. When calculating the replacement difficulty coefficient of the faulty assembly, the basic difficulty coefficients of the associated assemblies before the faulty assembly will be superimposed on the faulty assembly, thereby determining the replacement difficulty coefficient of the faulty assembly to be 1+8+1.5=10.5. If the replacement difficulty coefficient is less than or equal to 5 (the threshold value can be considered from the actual carrying capacity of the mobile terminal, the minimum construction area for placing the assembly on site to avoid obstacles, the time required for disassembly, etc.), it is judged to be easy to disassemble, then the faulty assembly is classified as non-easy to disassemble.

[0052] Furthermore, the disassembly order also needs to be considered. Assuming that the faulty assembly is ranked 10th, the basic difficulty coefficients of all must-disassembled assemblies and faulty assemblies are 1, and the replacement difficulty coefficient of the faulty assembly is 10. Although all must-disassembled assemblies and faulty assemblies can theoretically be disassembled on site, the weight of all the equipment required exceeds the actual carrying capacity of the mobile terminal or the required floor space for placing all assemblies after disassembly exceeds the minimum construction area, making on-site disassembly unrealistic. Therefore, the faulty assembly is still classified as non-easy to disassemble.

[0053] In the specific implementation process, the system first determines the faulty assembly through the user terminal. Then, the server accesses the preset database, which contains the complete assembly information of the vehicle. For a specific example, suppose the faulty assembly is the oil pump of the engine. The system will query all assemblies related to the oil pump, such as the oil filter, oil line, crankshaft, etc. The system will analyze the assembly order of these assemblies. For example, it may be necessary to remove the oil filter and part of the oil line before accessing the oil pump.

[0054] Next, the system will evaluate the difficulty of removing the oil pump. Assume that the oil pump replacement difficulty coefficient is 4. At the same time, the system will check whether the tools required for removal can be carried by the mobile terminal. If all these conditions are met, the system will determine that the oil pump is an easy-to-remove assembly.

[0055] Based on this judgment, the system will generate a detailed repair plan. If it is determined to be easy to disassemble, the system will generate a dispatch instruction, including a list of tools to be brought, spare oil pumps, oil and other materials, as well as detailed instructions for disassembly and assembly steps. This instruction will be sent to the nearest mobile terminal so that it can quickly reach the user's location for on-site repairs.

[0056] Compared with traditional maintenance methods, the technical solution of the present invention can more accurately determine the type of faulty assembly, thereby making more reasonable maintenance decisions. Traditional methods may rely too much on the experience of maintenance personnel, which is prone to misjudgment, resulting in unnecessary towing or excessive maintenance. The present invention uses a systematic and data-based method, combined with the actual structure and assembly relationship of the vehicle, to more objectively and accurately evaluate the feasibility of maintenance.

[0057] In some preferred embodiments, the specific steps in step S12 include: S121. When the faulty assembly is the first assembly to be disassembled in the disassembly sequence and all equipment required to disassemble the faulty assembly can be carried by the mobile terminal, the type of the faulty assembly is classified as easy to disassemble; S122. When the faulty assembly is the first assembly to be disassembled in the disassembly sequence and any equipment required to disassemble the faulty assembly cannot be carried by the mobile terminal, the type of the faulty assembly is classified as non-easy to disassemble; S123. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, perform the following steps: S1231. According to the disassembly sequence, all assemblies that must be disassembled before disassembling the faulty assembly are obtained and used as the assemblies that must be disassembled; S1232. When all equipment required to disassemble the faulty assembly and all necessary disassembled assemblies can be carried by the mobile terminal, the type of the faulty assembly is classified as easy to disassemble; S1233. When any piece of equipment required to disassemble the faulty assembly and all the necessary disassembled assemblies cannot be carried by the mobile terminal, the type of the faulty assembly is classified as non-easy to disassemble.

[0058] This embodiment involves classifying and judging the faulty assembly according to its position in the disassembly sequence, considering the portability of the equipment required for disassembly, and introducing the concept of a must-disassemble assembly to handle the faulty assembly that is not the first to be disassembled. These technical features quickly determine whether it is necessary to consider the disassembly of other related assemblies by judging whether the faulty assembly is the first to be disassembled, judge whether it is suitable for repair on a mobile terminal by considering the portability of the equipment required for disassembly, and ensure that the difficulty of disassembly of all related assemblies is taken into account when judging the faulty assembly that is not the first to be disassembled by introducing the concept of a must-disassemble assembly.

[0059] During implementation, the present invention can achieve these key features in a variety of ways. For example, to determine the position of the faulty assembly in the disassembly sequence, a preset database can be used to store the assembly disassembly sequence of various vehicle models, and then the disassembly position of the specific faulty assembly can be obtained by querying the database. For the portability of the equipment required for disassembly, an equipment list can be established, including the weight, volume and other information of each equipment, and the carrying capacity threshold of the mobile terminal can be set, such as the weight not exceeding 50 kilograms and the volume not exceeding 1 cubic meter. When the total weight and total volume of all equipment required for disassembly do not exceed the threshold, it is determined to be portable.

[0060] When the concept of must-disassemble assemblies is introduced, a recursive algorithm can be used to obtain all must-disassemble assemblies. Specifically, starting from the faulty assembly, the assemblies that must be disassembled are searched step by step until the assembly that must be disassembled first is found. This ensures that all relevant must-disassemble assemblies are taken into account.

[0061] There are close connections and interactions between these features. For example, the position of the faulty assembly in the disassembly sequence directly affects whether it is necessary to consider the assembly that must be disassembled, and the introduction of the assembly that must be disassembled expands the scope of equipment that needs to be considered. This comprehensive consideration makes the judgment more comprehensive and accurate. At the same time, this method cooperates with the steps mentioned above to obtain the associated assembly, forming a complete judgment process, which can more accurately evaluate the repair difficulty of the faulty assembly.

[0062] In specific implementation, the technical solution of the present invention first determines whether the faulty assembly is the assembly to be disassembled first. If so, the type is directly determined based on the portability of the equipment required for disassembly. For example, if the faulty assembly is a small sensor on the engine, and disassembly only requires a small wrench and a screwdriver, which can obviously be carried by a mobile terminal, then the sensor is classified as easy to disassemble.

[0063] If the faulty assembly is not the first assembly to be disassembled, the concept of the assembly that must be disassembled is introduced, and the difficulty of disassembling all related assemblies is considered. For example, if the faulty assembly is a gearbox, then before disassembling the gearbox, it may be necessary to disassemble multiple assemblies that must be disassembled, such as the oil pump assembly. In this case, the present invention will consider whether the equipment required to disassemble all these assemblies that must be disassembled can be carried by the mobile terminal. If all equipment can be carried, such as small tools and lightweight jacking equipment, the gearbox is still classified as easy to disassemble; if large lifting equipment or special disassembly tools are required, it is classified as non-easy to disassemble.

[0064] This judgment method can effectively distinguish between easily disassembled and non-easy-to-disassemble faulty assemblies, providing an accurate basis for subsequent maintenance decisions. For easily disassembled faulty assemblies, you can choose to dispatch a mobile terminal for on-site maintenance or notify the user to go to the maintenance terminal; for non-easy-to-disassemble faulty assemblies, directly notify the user to go to the maintenance terminal for maintenance. This classification method helps improve maintenance efficiency, optimize resource allocation, and provide users with more appropriate maintenance solutions.

[0065] In order to better understand the technical solution of the present invention, a specific embodiment is provided below: Suppose a car's headlight fails. The system first determines the position of the headlight in the disassembly order through a preset database. The query results show that the headlight is one of the first assemblies to be disassembled. Next, the system checks the list of equipment required to disassemble the headlight, including: cross screwdriver, flat screwdriver, small wrench, headlight tester. The system queries the equipment database and finds that the total weight of these tools is 3 kilograms and the total volume is 0.02 cubic meters, which does not exceed the carrying capacity threshold of the mobile terminal (assuming 50 kilograms and 1 cubic meter). Therefore, the system classifies the headlight failure as easy to disassemble.

[0066] Based on this judgment result, the system generates a dispatch instruction and sends it to the nearest mobile terminal. After receiving the instruction, the mobile terminal prepares the tools according to the equipment list provided by the system and then goes to the user's location. After the maintenance personnel arrive at the scene, they can quickly disassemble and replace the faulty headlight. The whole process may only take about 30 minutes.

[0067] Compared with traditional maintenance methods, which may require users to send their vehicles to a repair shop regardless of the type of fault, this is not only time-consuming but may also cause unnecessary trouble. The present invention can provide on-site repair services under appropriate circumstances by accurately determining the type of faulty assembly, greatly improving maintenance efficiency. At the same time, this method can also optimize the allocation of maintenance resources, avoid simple faults occupying the resources of the repair shop, and thus improve overall maintenance efficiency.

[0068] In addition, the method of the present invention is highly adaptable and extensible. With the development of vehicle technology and the emergence of new faults, new maintenance scenarios can be dealt with by simply updating the disassembly sequence and equipment information in the database. This flexibility enables the method of the present invention to continuously provide accurate fault classification and maintenance suggestions, bringing long-term benefits to the vehicle maintenance industry.

[0069] In some embodiments, the specific steps in step S2 include: S2A1. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, arrange all equipment required to disassemble the faulty assembly and all other assemblies that must be disassembled in the disassembly sequence and generate an equipment layout list; S2A2. When the dispatch instruction is sent to the mobile terminal, the equipment arrangement list is sent to the mobile terminal so that the relevant personnel of the mobile terminal can place all the devices used to dismantle the faulty assembly and all the assemblies that must be dismantled in order on the mobile terminal according to the sequence on the equipment arrangement list.

[0070] In this embodiment, when generating the equipment arrangement list, the present invention can be implemented in a variety of ways. One way is to directly arrange all the required equipment in the order of disassembly. For example, if the disassembly order is assembly A, assembly B, assembly C, then the equipment arrangement list may be: 1. Assembly A disassembly tools, 2. Assembly B disassembly tools, 3. Assembly C disassembly tools. Another way is to arrange in groups according to the order of disassembly, that is, first list all the tools required to disassemble assembly A, then list all the tools required to disassemble assembly B, and so on.

[0071] In addition, the equipment layout list can include more detailed information, such as the specific model, quantity, and usage of each piece of equipment. For example: 1. A assembly disassembly wrench (model XX, 2 pieces), 2. A assembly disassembly special tool (model YY, 1 piece), 3. B assembly disassembly electric screwdriver (model ZZ, 1 piece), etc. This detailed list can further improve the efficiency of preparation and operation.

[0072] In specific implementation, the method of the present invention can be carried out as follows: First, the system determines the disassembly order of the faulty assembly based on the pre-stored vehicle structure data. Assuming that the engine assembly needs to be disassembled, the system may generate the following disassembly order: 1. Disconnect the battery, 2. Disassemble the engine hood, 3. Disassemble the radiator, 4. Disconnect various pipe connections, 5. Disassemble the engine bracket, 6. Disassemble the engine. Then, the system will generate an equipment layout list according to this order, for example: 1. Insulated gloves and power-off tools, 2. Engine hood disassembly tool set, 3. Special radiator disassembly tool, 4. Pipe disassembly tool set, 5. Engine bracket disassembly tool, 6. Engine lifting equipment.

[0073] This list will be sent to the mobile terminal along with the dispatch instruction. After receiving the list, the staff on the mobile terminal will place the tools on the maintenance vehicle (i.e. the mobile terminal) in the order of the list. In this way, when they start the actual disassembly work, all the necessary tools have been placed in the order of use, which greatly improves work efficiency and reduces the time of finding and switching tools.

[0074] Compared with traditional maintenance methods, in which maintenance personnel may need to prepare tools based on experience, which may lead to omissions or improper preparation, resulting in frequent interruptions during the maintenance process to find or replace tools. The method of the present invention ensures that all necessary tools are ready in the correct order through a systematic equipment layout list, significantly improving maintenance efficiency and reducing the risk of operating errors. In addition, this method also provides clear guidance for maintenance personnel who are not familiar with specific models, helping to improve the consistency of maintenance quality.

[0075] In some embodiments, the specific steps in step S2 include: S2B1. When multiple faulty assemblies are interrelated assemblies, arrange all spare assemblies used to replace the faulty assemblies in assembly order and generate an assembly layout list; S2B2. When the dispatch instruction is sent to the mobile terminal, the assembly arrangement list is sent to the mobile terminal so that the relevant personnel of the mobile terminal can place all spare assemblies in order on the mobile terminal according to the sequence on the assembly arrangement list and replace all faulty assemblies in order.

[0076] In this embodiment, in the specific implementation process, the generation of the assembly layout list can be achieved in a variety of ways. For example, based on the pre-established vehicle model database, the assembly order of the corresponding vehicle model can be automatically obtained according to the vehicle identification number, and then the faulty assemblies that need to be replaced are arranged in this order to generate a list. Another way is to use an artificial intelligence algorithm to analyze the vehicle structure diagram and the maintenance manual to automatically generate the optimal assembly disassembly and assembly sequence. The maintenance personnel place all the spare assemblies in order on the maintenance vehicle according to the order on the assembly layout list. When the maintenance personnel go to the site to replace the spare assemblies, the orderly arrangement enables the maintenance personnel to find and take out the required spare assemblies more easily. At the same time, the order on the assembly layout list itself can also provide guidance to the maintenance personnel, so that the maintenance personnel can correctly and orderly install all the spare assemblies to achieve fast and efficient maintenance results.

[0077] This method not only simplifies the operation process for maintenance personnel, but also greatly reduces the risk of errors. Especially when dealing with complex, interrelated multiple faulty assemblies, the advantages of this method are more obvious, and it can significantly improve the quality and efficiency of maintenance. For example, when replacing an engine assembly, multiple related components may be involved, such as the intake system, cooling system, transmission system, etc. Through the assembly layout list, maintenance personnel can clearly understand the order of disassembly and assembly of each component, avoiding additional work or damage caused by incorrect sequence.

[0078] By judging the type of faulty assembly, determining the associated assembly and disassembly sequence, and combining the assembly layout list in this solution, a complete and efficient vehicle fault repair process is formed. This combination not only solves the problem of how to judge whether the faulty assembly can be repaired on site, but also further optimizes the specific operation process of on-site repair, thereby comprehensively improving the efficiency and quality of vehicle fault repair.

[0079] The list can also include the special tools and safety precautions required for each assembly. After receiving this list on the mobile terminal, the maintenance personnel can prepare the tools and spare assemblies in the correct order and perform the replacement operation.

[0080] Compared with the prior art, traditional vehicle maintenance methods usually rely on the maintenance personnel's experience and paper maintenance manuals, which are prone to misjudgment or operational errors. The present invention greatly reduces the possibility of human error through intelligent fault diagnosis and precise maintenance guidance. Especially when dealing with complex, multi-assembly related faults, the present method can provide clear operation instructions, avoiding the problems of confusion in disassembly and assembly order, missing steps, etc. that may occur in traditional methods.

[0081] In some embodiments, the specific steps in step S2 include: S2C1. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, a first equipment list is generated based on all equipment required to disassemble the faulty assembly and all necessary disassembly assemblies; S2C2. When the first notification information is sent to the user terminal, the first equipment list is sent to the maintenance end so that the relevant personnel of the maintenance end can prepare all the equipment required for disassembling the faulty assembly and all the assemblies that must be disassembled according to the first equipment list.

[0082] In some embodiments, the specific steps in step S2 include: S2D1. When multiple faulty assemblies are mutually related assemblies, a first assembly list is generated based on all spare assemblies for replacing the faulty assembly; S2D2. When the first notification information is sent to the user terminal, the first assembly list is sent to the maintenance end so that the relevant personnel of the maintenance end can prepare all spare assemblies according to the first assembly list.

[0083] In the above embodiment, on-site maintenance at the mobile terminal pays more attention to efficiency. The above embodiment arranges the required equipment and spare assemblies in an orderly manner on the mobile terminal in advance, which can greatly improve the maintenance efficiency of the maintenance personnel on site. In contrast, the present embodiment requires the user to go to the repair shop for maintenance (hereinafter referred to as in-store maintenance). This in-store maintenance pays more attention to the rapid deployment of special workstations. Therefore, the required equipment and spare assemblies only require advance preparation but do not require orderly arrangement. For example, when the user is driving to the repair shop, the maintenance personnel of the repair shop (i.e., the maintenance terminal) prepares the special required equipment and special spare assemblies at the same time according to the first equipment list. Therefore, when the user arrives at the repair shop, on the one hand, the maintenance work can be started immediately, and on the other hand, special car and repair services can be provided, which is conducive to avoiding the misuse of the required equipment and spare assemblies, thereby facilitating the improvement of user experience.

[0084] In some embodiments, the specific steps in step S3 include: S3A1. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, a second equipment list is generated based on all equipment required to disassemble the faulty assembly and all necessary disassembly assemblies; S3A2. When the second notification information is sent to the user terminal, the second equipment list is sent to the maintenance end so that the relevant personnel of the maintenance end prepare all the equipment required for disassembling the faulty assembly and all the assemblies that must be disassembled according to the second equipment list.

[0085] In some embodiments, the specific steps in step S3 include: S3B1. When multiple faulty assemblies are mutually related assemblies, a second assembly list is generated based on all spare assemblies used to replace the faulty assembly; S3B2. When the second notification information is sent to the user terminal, the second assembly list is sent to the maintenance end so that the relevant personnel of the maintenance end can prepare all spare assemblies according to the second assembly list.

[0086] Similar to the above embodiment, the second equipment list and the second assembly list are both used to help maintenance personnel quickly deploy special workstations and realize fast maintenance services for special vehicles and special repairs.

[0087] In some embodiments, the specific steps in step S2 include: S2E1. After determining that the type is easily disassembled, an instruction message is sent to the maintenance end; the instruction message is used to command the maintenance end to check the existing inventory to determine whether there is a spare assembly that can replace the faulty assembly; S2E2. When the first feedback information sent by the maintenance end is obtained, a dispatch instruction is generated and sent to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly; the first feedback information is generated when the maintenance end determines that there is a spare assembly in the existing inventory; S2E3. When the second feedback information sent by the maintenance end is obtained, the first notification information is generated and sent to the user terminal to enable the user to go to the location of the maintenance end and repair the faulty assembly; the second feedback information is generated when the maintenance end determines that there is no spare assembly in the existing inventory.

[0088] In this embodiment, the spare assembly carried by the mobile terminal is provided by the maintenance terminal. Therefore, in actual application, for faulty assemblies that are easy to disassemble, it is also necessary to determine whether the maintenance terminal can provide the required spare assembly. If it can be provided, the mobile terminal will be dispatched for on-site repair; if it cannot be provided, the user will be notified to go to the store for repair.

[0089] The present invention provides a vehicle fault maintenance system, comprising a user terminal 2, a server 1, a maintenance terminal 3 and a mobile terminal 4; the user terminal 2 is used to determine all fault assemblies causing the fault through a preset intelligent question-answering model and feed back to the server 1; Server 1 is used to perform the following steps: S1. After all faulty assemblies causing the fault are determined through the user terminal, the types of all faulty assemblies are determined; the types include easily disassembled and non-easy disassembled types; S2. When all faulty assemblies are of the easily disassembled type, a dispatch instruction is generated and sent to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or a first notification message is generated and sent to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly; S3. When the type of any faulty assembly is non-dismantlable, generate a second notification message and send the second notification message to the user terminal so that the user can go to the location of the maintenance terminal and repair the faulty assembly.

[0090] In this embodiment, the mobile terminal 4 can be a maintenance vehicle equipped with professional maintenance tools and spare assemblies. The system can automatically generate a list of required tools and spare parts according to the type of faulty assembly to ensure that the equipment carried by the mobile terminal 4 can meet the maintenance needs. In addition, the mobile terminal 4 can also be equipped with remote diagnostic equipment to conduct remote consultations with experts at the maintenance terminal 3 when necessary, further improving the accuracy and efficiency of maintenance.

[0091] Maintenance Terminal 3 can be a traditional maintenance workshop equipped with more comprehensive maintenance equipment and professional technicians. For non-dismantling faults or complex maintenance tasks, the system will directly notify the user to go to Maintenance Terminal 3. This can avoid unnecessary door-to-door service and improve overall maintenance efficiency.

[0092] In actual application, the user interacts with the intelligent question-answering model through the user terminal 2 (such as mobile phones, tablets, computers and other electronic devices), and the intelligent question-answering model gradually asks and guides the user to check the vehicle, thereby analyzing and determining the faulty assembly. Generally, the intelligent question-answering model can determine the specific faulty parts in the faulty assembly through multiple rounds of questions and answers, but requires the user to be familiar with vehicle knowledge. In view of the fact that the maintenance terminal 3 and the mobile terminal 4 of the present invention mainly adopt the maintenance method of replacing the faulty assembly rather than replacing the faulty parts, the intelligent question-answering model only needs to be able to determine the faulty assembly, which not only reduces the design requirements of the intelligent question-answering model, but also can meet the normal use of users who are not familiar with vehicle knowledge.

[0093] In some embodiments, the vehicle breakdown repair system further includes a factory end 5 , which is used to receive the faulty assembly from the repair end 3 and the mobile end 4 and repair the faulty assembly.

[0094] In this embodiment, the fault is often caused by the failure of certain accessories in the faulty assembly. The maintenance end 3 only needs to analyze the faulty assembly and then directly replace the assembly to quickly complete the repair. The maintenance end 3 does not need to analyze the specific faulty accessories, and the factory end 5 is responsible for analyzing the specific faulty accessories from the faulty assembly, thereby repairing or replacing the faulty accessories, thereby completing the return of the faulty assembly to the factory for repair. This division of labor can reduce the workload of the maintenance end 3 and improve the maintenance efficiency of the maintenance end 3, so that the maintenance end 3 can handle more maintenance business.

[0095] As a professional maintenance center, the factory terminal 5 is capable of handling various complex faults, which solves the technical limitations that the maintenance terminal 3 and the mobile terminal 4 may face when handling complex faults. At the same time, the setting of the factory terminal 5 optimizes the resource allocation of the entire maintenance system. The maintenance terminal 3 and the mobile terminal 4 can focus on fault diagnosis and simple repairs, while the complex repair work is handed over to the factory terminal 5. This division of labor significantly improves the operating efficiency of the entire maintenance system.

[0096] Specifically, when a user's vehicle breaks down, the system first performs a preliminary diagnosis through the user terminal 2 to determine the faulty assembly. If the faulty assembly is determined to be easy to disassemble and can be repaired on site, the mobile terminal 4 will be dispatched for on-site repair. If the faulty assembly is determined to be non-easy to disassemble or cannot be repaired on site, the system will notify the user to send the vehicle to the nearest maintenance terminal 3. After receiving the faulty vehicle, the maintenance terminal 3 will conduct further diagnosis and evaluation. If it is found that the faulty assembly requires professional repair or replacement, the maintenance terminal 3 will disassemble the faulty assembly and send the fault information to the factory terminal 5 through the system. After receiving the information, the factory terminal 5 will arrange a special maintenance team and equipment for processing. For example, for a complex electronic control unit failure, the factory terminal 5 may need to use professional circuit diagnostic equipment and software for in-depth analysis, which is a task that is difficult for ordinary maintenance terminals 3 to complete. After the factory terminal 5 completes the repair, it will send the repaired assembly back to the original maintenance terminal 3 or the nearest maintenance terminal 3, and the maintenance terminal 3 will complete the installation of the assembly and the final vehicle commissioning.

[0097] Compared with the prior art, the present invention significantly improves the ability to handle complex faults by introducing the factory side. In the traditional maintenance model, each maintenance point often needs to handle all types of faults independently, which may result in some complex faults not being solved in a timely or effective manner. The present invention not only improves the quality of maintenance by centralizing complex faults to professional factory-side processing, but also optimizes resource allocation, allowing the entire maintenance network to operate more efficiently. At the same time, this model also reduces the equipment investment and technical training costs of each maintenance end, because they no longer need to prepare equipment and technology to handle all types of complex faults. This innovative maintenance model brings new solutions to vehicle fault maintenance, effectively solving the problem of how to efficiently handle fault assemblies received from the maintenance end and the mobile end.

[0098] Please refer to Figure 2 , Figure 2 A vehicle fault repair device in some embodiments of the present invention is applied to a server of a vehicle fault repair system. The vehicle fault repair device is integrated in a back-end control device in the form of a computer program, and includes: The judgment module 100 is used to judge the types of all faulty assemblies after determining all faulty assemblies causing the fault through the user terminal; the types include easy-to-disassemble type and non-easy-to-disassemble type; The first control module 200 is used to generate a dispatch instruction and send the dispatch instruction to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or generate a first notification message and send the first notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly when all the faulty assemblies are of the easily dismantled type; The second control module 300 is used to generate second notification information and send the second notification information to the user terminal when the type of any faulty assembly is non-dismantlable, so as to enable the user to go to the location of the maintenance end and repair the faulty assembly.

[0099] In some embodiments, the determination module 100 is used to determine the types of all faulty assemblies after determining all faulty assemblies causing a fault through a user terminal: S11. Based on a preset database, an assembly having a continuous assembly relationship with the faulty assembly is obtained and used as an associated assembly; the continuous assembly relationship means that the faulty assembly has a unique assembly sequence and disassembly sequence with all associated assemblies; S12. Determine the assembly type of the faulty assembly based on the disassembly sequence.

[0100] In some embodiments, the determination module 100 performs the following when used to determine the assembly type of the faulty assembly according to the disassembly sequence: S121. When the faulty assembly is the first assembly to be disassembled in the disassembly sequence and all equipment required to disassemble the faulty assembly can be carried by the mobile terminal, the type of the faulty assembly is classified as easy to disassemble; S122. When the faulty assembly is the first assembly to be disassembled in the disassembly sequence and any equipment required to disassemble the faulty assembly cannot be carried by the mobile terminal, the type of the faulty assembly is classified as non-easy to disassemble; S123. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, perform the following steps: S1231. According to the disassembly sequence, all assemblies that must be disassembled before disassembling the faulty assembly are obtained and used as the assemblies that must be disassembled; S1232. When all equipment required to disassemble the faulty assembly and all necessary disassembled assemblies can be carried by the mobile terminal, the type of the faulty assembly is classified as easy to disassemble; S1233. When any piece of equipment required to disassemble the faulty assembly and all the necessary disassembled assemblies cannot be carried by the mobile terminal, the type of the faulty assembly is classified as non-easy to disassemble.

[0101] In some embodiments, when the types of all faulty assemblies are easily disassembled, the first control module 200 generates a dispatch instruction and sends the dispatch instruction to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or generates a first notification message and sends the first notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly, and executes: S2A1. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, arrange all equipment required to disassemble the faulty assembly and all other assemblies that must be disassembled in the disassembly sequence and generate an equipment layout list; S2A2. When the dispatch instruction is sent to the mobile terminal, the equipment arrangement list is sent to the mobile terminal so that the relevant personnel of the mobile terminal can place all the devices used to dismantle the faulty assembly and all the assemblies that must be dismantled in order on the mobile terminal according to the sequence on the equipment arrangement list.

[0102] In some embodiments, when the types of all faulty assemblies are easily disassembled, the first control module 200 generates a dispatch instruction and sends the dispatch instruction to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or generates a first notification message and sends the first notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly, and executes: S2B1. When multiple faulty assemblies are interrelated assemblies, arrange all spare assemblies used to replace the faulty assemblies in order of assembly and generate an assembly layout list; S2B2. When the dispatch instruction is sent to the mobile terminal, the assembly arrangement list is sent to the mobile terminal so that the relevant personnel of the mobile terminal can place all spare assemblies in order on the mobile terminal according to the sequence on the assembly arrangement list and replace all faulty assemblies in order.

[0103] In some embodiments, when the types of all faulty assemblies are easily disassembled, the first control module 200 generates a dispatch instruction and sends the dispatch instruction to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or generates a first notification message and sends the first notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly, and executes: S2C1. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, a first equipment list is generated based on all equipment required to disassemble the faulty assembly and all necessary disassembly assemblies; S2C2. When the first notification information is sent to the user terminal, the first equipment list is sent to the maintenance end so that the relevant personnel of the maintenance end can prepare all the equipment required for disassembling the faulty assembly and all the assemblies that must be disassembled according to the first equipment list.

[0104] In some embodiments, when the types of all faulty assemblies are easily disassembled, the first control module 200 generates a dispatch instruction and sends the dispatch instruction to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or generates a first notification message and sends the first notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly, and executes: S2D1. When multiple faulty assemblies are mutually related assemblies, a first assembly list is generated based on all spare assemblies for replacing the faulty assembly; S2D2. When the first notification information is sent to the user terminal, the first assembly list is sent to the maintenance end so that the relevant personnel of the maintenance end can prepare all spare assemblies according to the first assembly list.

[0105] In some embodiments, when the type of any faulty assembly is non-dismantlable, the second control module 300 generates a second notification message and sends the second notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly: S3A1. When the faulty assembly is not the first assembly to be disassembled in the disassembly sequence, a second equipment list is generated based on all equipment required to disassemble the faulty assembly and all necessary disassembly assemblies; S3A2. When the second notification information is sent to the user terminal, the second equipment list is sent to the maintenance end so that the relevant personnel of the maintenance end prepare all the equipment required for disassembling the faulty assembly and all the assemblies that must be disassembled according to the second equipment list.

[0106] In some embodiments, when the type of any faulty assembly is non-dismantlable, the second control module 300 generates a second notification message and sends the second notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly: S3B1. When multiple faulty assemblies are mutually related assemblies, a second assembly list is generated based on all spare assemblies used to replace the faulty assembly; S3B2. When the second notification information is sent to the user terminal, the second assembly list is sent to the maintenance end so that the relevant personnel of the maintenance end can prepare all spare assemblies according to the second assembly list.

[0107] In some embodiments, when the types of all faulty assemblies are easily disassembled, the first control module 200 generates a dispatch instruction and sends the dispatch instruction to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly, or generates a first notification message and sends the first notification message to the user terminal so that the user goes to the location of the maintenance terminal and repairs the faulty assembly, and executes: S2E1. After determining that the type is easily disassembled, an instruction message is sent to the maintenance end; the instruction message is used to command the maintenance end to check the existing inventory to determine whether there is a spare assembly that can replace the faulty assembly; S2E2. When the first feedback information sent by the maintenance end is obtained, a dispatch instruction is generated and sent to the mobile terminal so that the mobile terminal goes to the location of the vehicle and replaces the faulty assembly; the first feedback information is generated when the maintenance end determines that there is a spare assembly in the existing inventory; S2E3. When the second feedback information sent by the maintenance end is obtained, the first notification information is generated and sent to the user terminal to enable the user to go to the location of the maintenance end and repair the faulty assembly; the second feedback information is generated when the maintenance end determines that there is no spare assembly in the existing inventory.
