[0061] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0062] The following description, with reference to the accompanying drawings, outlines a method, apparatus, vehicle, and storage medium for remote diagnosis and control of NVH (Noise, Vibration, and Harshness) issues according to embodiments of this application.

[0063] Before introducing the remote diagnostic control method for NVH problems according to the embodiments of this application, let's briefly introduce the data control methods of the prior art and the data control method proposed in this application.

[0064] Specifically, such as Figure 1 As shown, Figure 1 The red data flow ① represents the current NVH data acquisition, transmission, and processing methods. Figure 2 The blue data flows ②, ③, and ④ represent the control methods of the NVH data acquisition, transmission, and diagnostic system proposed in this application, which are compatible with different scenario requirements. They are, respectively, a data transmission method based on a preset PC-based unified acquisition platform, a data transmission method based on a preset integrated portable data acquisition system, and a data acquisition and transmission method based on a preset mobile terminal APP.

[0065] The following is about Figure 1 The functional components are described as follows:

[0066] (1) Sensors: Data acquisition elements, typically accelerometers, microphone sensors, Hall effect sensors, speed sensors, etc.

[0067] (2) Data acquisition hardware: Head, LMS and BK are the hardware acquisition systems of the three major data acquisition hardware suppliers.

[0068] (3) Acquisition software: Artimes, Testlab, and Pulse are the corresponding software acquisition systems provided by the three major suppliers Head, LMS, and BK, respectively.

[0069] (4) Cloud disk: Temporary data storage address. The raw data collected by the PC is temporarily stored in the designated location on the cloud disk.

[0070] (5) MDP system: a data storage and post-processing system.

[0071] (6) Local computer: The work computer used by the testers in the office, usually a desktop computer.

[0072] (7) Portable data acquisition system: It has NVH data acquisition, analysis and wireless transmission functions, and can directly transmit the acquired data to the data warehouse system via 5G and wifi.

[0073] (8) Unified data acquisition platform: PC-based data acquisition software system with powerful data acquisition, real-time analysis and post-processing functions. The acquired data can be transmitted to the data warehouse system through this platform.

[0074] (9) Mobile terminal: Smart phone terminal with sound signal recording capability.

[0075] (10) Customized APP: Mobile application software adapted to mobile devices, with real-time NVH data analysis and transmission functions.

[0076] (11) Data Warehouse System: A brand-new data acquisition, storage and post-processing system with a certain degree of intelligent diagnostic function. The system is developed based on a browser architecture and can interact with external devices based on network addresses.

[0077] Depend on Figure 1 It can be seen that the existing data control method ① can only transmit NVH data to a local desktop computer or the NVH department's self-developed MDP system via cloud disks or USB flash drives for post-processing. This data interaction is relatively complex and the processing methods are not standardized. In contrast, the data control methods ②, ③, and ④ proposed in this application, while retaining the original cloud disk data transmission, add data flow modes primarily using 5G wide area networks and WiFi local area networks. By centrally transmitting NVH data to the NVH department's self-developed data warehouse system, testers can exchange data and process it centrally within the data warehouse system, thereby improving the efficiency of testing and analysis.

[0078] This application divides the complete NVH testing process and the testing tools used into scenarios and functions. With the definition of application scenarios as the core, it derives three data control methods and uses unified data storage and intelligent diagnostic programs to realize an automatic diagnostic system that does not rely on experienced engineers.

[0079] The following describes the remote diagnostic and control method for NVH problems proposed in this application.

[0080] Specifically, Figure 2 This is a flowchart illustrating a remote diagnostic and control method for NVH problems provided in an embodiment of this application.

[0081] like Figure 2 As shown, the remote diagnostic and control method for NVH problems includes the following steps:

[0082] In step S201, network data of the current NVH problem and the location where the current NVH problem occurs are obtained.

[0083] Specifically, embodiments of this application can obtain the current NVH problem based on user descriptions and inputs, or by collecting vehicle NVH data using sensors and testing equipment, without further specific limitations. Furthermore, embodiments of this application can obtain network data of the location where the current NVH problem occurs using mobile testing equipment.

[0084] Furthermore, in some embodiments, after obtaining the network data of the current NVH problem and the location where the current NVH problem occurs, the method further includes: based on the network data, determining whether the current network strength is greater than a preset strength, and determining whether the current NVH problem belongs to a predefined application scenario; if the current network strength is greater than the preset strength and the current NVH problem belongs to a predefined application scenario, then the current NVH problem is determined to meet the preset scenario type matching conditions; otherwise, the current NVH problem is determined not to meet the preset scenario type matching conditions.

[0085] The preset strength can be a strength pre-set by those skilled in the art, and is not specifically limited here.

[0086] Furthermore, based on the types of NVH performance testing and diagnostic services—namely, vehicle and bench-level NVH performance development, factory production NVH performance monitoring, after-sales NVH performance maintenance, and NVH international business development—the predefined application scenarios can be subdivided into seven application scenarios. These predefined application scenarios include: Figure 3 As shown, it includes:

[0087] Scenario 1: Efficient data collection for routine NVH performance testing, mainly data collection of vehicle NVH issues during normal project development.

[0088] Scenario 2: Real-time tracking of intermittent NVH quality problems refers to NVH problems that are intermittent, sudden, and irregular, requiring testing equipment to monitor them in real time in order to capture vibration and noise data when the problem occurs.

[0089] Scenario 3: Remote joint diagnosis of NVH performance at the test site refers to NVH issues raised by the test site, which is far away from the R&D base, and which need to be resolved in a timely manner.

[0090] Scenario 4: Supplier component NVH performance acceptance refers to the requirement that suppliers provide corresponding data proof when individual components in bench condition are required to meet specific NVH indicators.

[0091] Scenario 5: Production line NVH performance consistency monitoring refers to the need for timely monitoring when products on the production line exhibit unstable NVH performance issues, so as to obtain problem data.

[0092] Scenario 6: Remote diagnosis of NVH issues in after-sales complaints refers to establishing a remote assistance channel with the consumer or 4S store when the customer or 4S store raises relevant NVH issues.

[0093] Scenario 7: International NVH performance business development. When NVH problems occur in internationally developed models or models sold overseas, timely remote assistance is needed to quickly diagnose the problems.

[0094] Specifically, this application embodiment considers the network environment where the NVH problem occurs, determines whether the current network strength is greater than the preset strength based on the acquired network data, and determines whether the current NVH problem belongs to a predefined application scenario based on the description and input of the NVH problem.

[0095] If the current network strength is greater than the preset strength and the current NVH problem belongs to a predefined application scenario, then the current NVH problem is determined to meet the preset scenario type matching conditions.

[0096] If the current network strength is less than the preset strength—for example, if there is no wireless communication network signal, such as 5G or Wi-Fi, at the location where the NVH problem occurs, or if the network signal is very weak—then the current NVH problem is determined not to meet the preset scenario type matching conditions. Furthermore, if the current NVH problem does not belong to a predefined application scenario, it is also determined not to meet the preset scenario type matching conditions.

[0097] In step S202, based on the current NVH problem and / or network data, when it is determined that the current NVH problem meets the preset scenario type matching conditions, the target transmission method is determined according to the problem type of the current NVH problem.

[0098] The target transmission methods include data acquisition and transmission based on a preset mobile terminal APP, data transmission based on a preset integrated portable data acquisition system, and data transmission based on a preset unified acquisition platform on a PC.

[0099] Furthermore, in some embodiments, determining the target transmission method based on the current NVH problem type includes: determining whether the user has a time-limited requirement for diagnostic results; if the user has a time-limited requirement for diagnostic results, then if the time-limited requirement is immediate, the target transmission method is determined to be a data transmission method based on a preset unified PC acquisition platform; if the time-limited requirement is non-immediate, the target transmission method is determined to be a data transmission method based on a preset integrated portable data acquisition system; otherwise, determining whether the problem type is noise; if the problem type is noise, the target transmission method is a data acquisition and transmission method based on a preset mobile terminal APP; otherwise, determining whether the problem type is vibration monitoring; if the problem type is vibration monitoring, the target transmission method is a data transmission method based on a preset integrated portable data acquisition system, and / or a data transmission method based on a preset unified PC acquisition platform.

[0100] The preset mobile terminal can be a mobile phone or other handheld communication device with shortwave radio communication function, and no specific limitation is made here.

[0101] Specifically, when the current NVH problem and / or network data are determined to meet the preset scenario type matching conditions, the corresponding application scenario in the predefined application scenario is matched according to the current NVH problem, and the data remote control method is reasonably selected according to the user's time limit requirements for the diagnostic results and the problem type of the current NVH problem.

[0102] Specifically, it determines whether the user has a time-limited requirement for the diagnostic results. If the user has a time-limited requirement for the diagnostic results, then when the time-limited requirement is an immediate requirement (i.e., a detailed NVH problem diagnosis and conclusion output are required immediately), the target transmission method is determined to be the data transmission method based on the preset PC-side unified acquisition platform.

[0103] Furthermore, if the user has a time limit requirement for the diagnostic results, and the time limit requirement is not an immediate requirement, that is, the user does not have a high requirement for the immediacy of the NVH problem diagnostic results, that is, there is no need for detailed problem diagnosis and conclusion output on site, then the target transmission method is determined to be the data transmission method based on the preset integrated portable data acquisition system.

[0104] Furthermore, if the user does not have a time limit requirement for the diagnostic results, then it is determined whether the NVH problem type is noise type. That is, if the current NVH problem is qualitatively judged as a noise problem, then the current problem type is determined to be noise type, and the target transmission method is determined to be the data collection and transmission method based on the preset mobile terminal APP.

[0105] Furthermore, if the NVH problem type is not noise type, then determine whether the problem type is vibration monitoring type. If the problem type is vibration monitoring type, that is, the problem diagnosis requires monitoring vibration signals, then determine the target transmission method as the data transmission method based on the preset integrated portable data acquisition system, or determine the target transmission method as the data transmission method based on the preset PC-side unified acquisition platform, or determine the target transmission method as both the data transmission method based on the preset integrated portable data acquisition system and the data transmission method based on the preset PC-side unified acquisition platform.

[0106] In step S203, the problem data of the current NVH problem is transmitted to the preset data warehouse system for diagnosis according to the target transmission method, and the first diagnostic result of the current NVH problem is obtained.

[0107] The pre-defined data warehouse system is a platform for centrally storing and managing NVH problem data. It can process and analyze large amounts of NVH problem data, has big data processing capabilities, and takes into account intelligent diagnosis. It can provide preliminary diagnostic results without relying on engineers' experience.

[0108] Specifically, after determining the target data transmission method based on the specific type of NVH problem and user needs, the problem data of the current NVH problem is transmitted to a preset data warehouse system for remote joint diagnosis using the target transmission method and wireless communication networks, such as 5G or WiFi networks. The preset data warehouse system uses built-in algorithms or models to analyze and process the NVH problem data to identify the potential causes of the NVH problem. After the preset data warehouse system completes the NVH problem diagnosis and analysis, the first diagnostic result of the current NVH problem is obtained.

[0109] Therefore, when diagnosing NVH problems, complex NVH issues can no longer rely on experienced or highly skilled engineers traveling to handle them. By integrating multiple data transmission methods, such as 5G and Wi-Fi networks, data transmission can be carried out to achieve remote joint diagnosis and improve testing efficiency.

[0110] Furthermore, in some embodiments, when transmitting the problem data of the current NVH problem to a preset data warehouse system for diagnosis according to the target transmission method, the method further includes: determining whether the current network speed is within a preset network speed range based on network data; if the current network speed is within the preset network speed range, then sequentially uploading the problem data of the current NVH problem to the preset data warehouse system, or sequentially temporarily storing the problem data of the current NVH problem to a preset test terminal, and then centrally uploading it to the preset data warehouse system after storage; if the current network speed is not within the preset network speed range, then sequentially temporarily storing the problem data of the current NVH problem to a preset test terminal, and then centrally uploading it to the preset data warehouse system after storage.

[0111] The preset network speed range can be a network speed range pre-set by those skilled in the art, and is not specifically limited here. Optionally, the preset test terminal can be a test computer.

[0112] Specifically, this application embodiment can select different transmission methods based on network speed. First, based on network data, the current network speed of the location where the NVH problem occurs is obtained. If the current network speed is within a preset network speed range, that is, the current network signal quality is good, then the problem data of the current NVH problem is transmitted sequentially to a preset data warehouse system in real time. Alternatively, the problem data of the current NVH problem can be temporarily stored sequentially to a preset test terminal according to user needs, and then uniformly uploaded to the preset data warehouse system after storage is completed.

[0113] Furthermore, if the current network speed is not within the preset network speed range, that is, the current network signal quality is poor, the problem data of the current NVH problem will be temporarily stored in the preset test terminal in sequence, and then uploaded to the preset data warehouse system in a centralized manner after storage is completed, thereby avoiding the risk of data transmission failure when the network conditions are poor.

[0114] Furthermore, in some embodiments, after obtaining the first diagnostic result of the current NVH problem, the method further includes: determining whether the first diagnostic result is valid; if the first diagnostic result is valid, then outputting the first diagnostic result; otherwise, executing the step of obtaining the on-site test result of the current NVH problem.

[0115] Specifically, after obtaining the first diagnostic result of the current NVH problem, this embodiment of the application determines whether the first diagnostic result is valid, such as whether the diagnostic result is accurate or complete. If the first diagnostic result is valid, the first diagnostic result is directly output; if the first diagnostic result is invalid, that is, the first diagnostic result is wrong or incomplete, the test personnel are arranged to go to the site where the NVH problem occurs to conduct the test and obtain the on-site test results of the current NVH problem.

[0116] Therefore, using the remote diagnostic control method for NVH problems proposed in this application does not mean completely abandoning the traditional method of on-site problem diagnosis by traveling test personnel. However, during the initial analysis of the problem, joint diagnosis based on remote data transmission should be prioritized to achieve cost reduction and efficiency improvement.

[0117] Furthermore, in some embodiments, after determining that the current NVH problem does not meet the preset scenario type matching conditions, the method further includes: obtaining the on-site test results of the current NVH problem, and determining whether remote joint diagnosis is required based on the on-site test results; if remote joint diagnosis is required, the problem data and the on-site test results are transmitted to a preset data warehouse system for remote joint diagnosis to obtain a second diagnosis result of the current NVH problem; otherwise, a third diagnosis result of the current NVH problem is obtained based on the on-site test results.

[0118] Specifically, after determining that the current NVH problem does not meet the preset scenario type matching conditions—that is, the current NVH problem does not belong to the predefined application scenario, or the current network strength is less than the preset strength—test engineers are first dispatched to the site to investigate, diagnose, and confirm the NVH problem. This obtains the on-site test results of the current NVH problem. Based on the complexity of the on-site test results, the severity of the problem, and whether the necessary conditions for remote joint diagnosis are met (such as network conditions), a further determination is made as to whether remote joint diagnosis is necessary. If remote joint diagnosis is required, the problem data and on-site test results are transmitted to a preset data warehouse system for remote joint diagnosis. After remote joint diagnosis, a second diagnostic result for the current NVH problem is obtained.

[0119] Furthermore, if it is determined that remote joint diagnosis is not necessary or is not feasible, a third diagnostic result is derived directly based on the intuitive analysis and experience of the test engineer using on-site test data.

[0120] Those skilled in the art should understand that a complete NVH test mainly comprises five stages, with data acquisition and analysis, data uploading, and performance diagnostics accounting for 85% of the time. Based on standard testing task calculations, utilizing a remote testing and diagnostic system can cumulatively improve efficiency by approximately 10%-20% across these five stages. Taking a single new hybrid project as an example, following standard operating procedures, this application can cumulatively reduce man-months after it is put into operation. This control method can also reduce the number of business trips, with an estimated increase in labor efficiency of approximately 20% and a reduction in development costs of 20%-30%.

[0121] To facilitate a clearer and more intuitive understanding by those skilled in the art of the NVH problem diagnosis method based on scenario definition and data control in the embodiments of this application, the following is combined with... Figure 4 Please provide a detailed explanation.

[0134] Therefore, this application divides the test types into scenarios. Based on the characteristics of different scenarios, it integrates various digital means such as wide area 5G network, local area network WiFi, mobile APP, and portable integrated data acquisition and data warehouse system. Without relying on the rich experience of individual engineers or the need to rely heavily on personnel mobility to solve problems, it achieves the goal of replacing personnel mobility with data mobility, thereby reducing costs and increasing efficiency, and empowering R&D with digital means.

[0135] The remote diagnostic control method for NVH problems proposed in this application, based on the current NVH problem and / or network data of the location where the current NVH problem occurs, determines the target transmission method according to the problem type of the current NVH problem when it is determined that the current NVH problem meets the preset scenario type matching conditions; the problem data of the current NVH problem is then transmitted to a preset data warehouse system for diagnosis according to the target transmission method to obtain the first diagnostic result of the current NVH problem. This solves the problems of high time and manpower costs and low efficiency of related technologies. By matching the corresponding data control method according to the specific usage scenario and utilizing a local data warehouse system for intelligent diagnosis, the efficiency of NVH problem diagnosis is improved, achieving cost reduction and efficiency improvement.

[0136] Next, referring to the accompanying drawings, a remote diagnostic control device for NVH problems according to an embodiment of this application is described.

[0137] Figure 5 This is a block diagram of a remote diagnostic control device for NVH problems according to an embodiment of this application.

[0138] like Figure 5 As shown, the remote diagnostic control device 10 for NVH problems includes: an acquisition module 100, a processing module 200, and a diagnostic module 300.

[0139] The module 100 is used to acquire the current NVH problem and the network data of the location where the current NVH problem occurs; the processing module 200 is used to determine the target transmission method according to the problem type of the current NVH problem when the current NVH problem meets the preset scenario type matching conditions based on the current NVH problem and / or network data; the diagnosis module 300 is used to transmit the problem data of the current NVH problem to a preset data warehouse system for diagnosis according to the target transmission method, and obtain the first diagnosis result of the current NVH problem.

[0140] Further, in some embodiments, the processing module 200 is configured to: determine whether the user has a time-limit requirement for the diagnostic results; if the user has a time-limit requirement for the diagnostic results, then if the time-limit requirement is an immediate requirement, determine that the target transmission method is a data transmission method based on a preset unified acquisition platform on a PC; if the time-limit requirement is a non-immediate requirement, determine that the target transmission method is a data transmission method based on a preset integrated portable data acquisition system; otherwise, determine whether the problem type is noise; if the problem type is noise, then the target transmission method is a data acquisition and transmission method based on a preset mobile terminal APP; otherwise, determine whether the problem type is vibration monitoring; if the problem type is vibration monitoring, then the target transmission method is a data transmission method based on a preset integrated portable data acquisition system, and / or a data transmission method based on a preset unified acquisition platform on a PC.

[0141] Furthermore, in some embodiments, after obtaining the network data of the current NVH problem and the location where the current NVH problem occurs, the acquisition module 100 is further configured to: determine, based on the network data, whether the current network strength is greater than a preset strength, and whether the current NVH problem belongs to a predefined application scenario; if the current network strength is greater than the preset strength and the current NVH problem belongs to a predefined application scenario, then the current NVH problem is determined to meet the preset scenario type matching condition; otherwise, the current NVH problem is determined not to meet the preset scenario type matching condition.

[0142] Furthermore, in some embodiments, after determining that the current NVH problem does not meet the preset scenario type matching conditions, the acquisition module 100 is further configured to: acquire the on-site test results of the current NVH problem, and determine whether remote joint diagnosis is required based on the on-site test results; if remote joint diagnosis is required, the problem data and the on-site test results are transmitted to a preset data warehouse system for remote joint diagnosis to obtain a second diagnosis result of the current NVH problem; otherwise, a third diagnosis result of the current NVH problem is obtained based on the on-site test results.

[0143] Furthermore, in some embodiments, after obtaining the first diagnostic result of the current NVH problem, the diagnostic module 300 is further configured to: determine whether the first diagnostic result is valid; if the first diagnostic result is valid, output the first diagnostic result; otherwise, execute the step of obtaining the on-site test result of the current NVH problem.

[0144] Furthermore, in some embodiments, when transmitting the current NVH problem data to a preset data warehouse system for diagnosis according to the target transmission method, the diagnosis module 300 is also used to: determine whether the current network speed is within a preset network speed range based on network data; if the current network speed is within the preset network speed range, then sequentially upload the current NVH problem data to the preset data warehouse system, or sequentially temporarily store the current NVH problem data to a preset test terminal, and then centrally upload it to the preset data warehouse system after storage; if the current network speed is not within the preset network speed range, then sequentially temporarily store the current NVH problem data to a preset test terminal, and then centrally upload it to the preset data warehouse system after storage.

[0145] It should be noted that the foregoing explanation of the embodiment of the remote diagnosis and control method for NVH problems also applies to the remote diagnosis and control device for NVH problems in this embodiment, and will not be repeated here.

[0146] The remote diagnostic control device for NVH problems proposed in this application, based on the current NVH problem and / or network data of the location where the current NVH problem occurs, determines the target transmission method according to the problem type of the current NVH problem when it is determined that the current NVH problem meets the preset scenario type matching conditions; and transmits the problem data of the current NVH problem to a preset data warehouse system for diagnosis according to the target transmission method to obtain the first diagnostic result of the current NVH problem. This solves the problems of high time and manpower costs and low efficiency of related technologies. By matching the corresponding data control method according to the specific usage scenario, the efficiency of NVH problem diagnosis is improved, achieving cost reduction and efficiency improvement.
