[0061] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0062] The following describes the NVH problem remote diagnosis control method, device, vehicle and storage medium of the embodiments of the present application with reference to the accompanying drawings.

[0063] Before introducing the remote diagnosis and control method for NVH problems according to the embodiment of the present application, a brief introduction will be given to the data control method of the prior art and the data control method proposed in the present application.

[0064] Specifically, if Figure 1 As shown, Figure 1 The red data flow ① in the middle represents the current NVH data collection, transmission and processing methods. Figure 2 The data flows ②, ③ and ④ in blue are the control methods of the NVH data acquisition, transmission and diagnosis system proposed in this application, which are compatible with the needs of different scenarios. They are respectively a data transmission method based on a preset PC-side 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 for Figure 1 The functional components in are described as follows:

[0066] (1) Sensor: data acquisition element, usually an accelerometer, microphone sensor, Hall sensor, speed sensor, 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 original data collected by the PC is temporarily stored in the designated location of the cloud disk.

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

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

[0072] (7) Portable data acquisition system: It has the functions of NVH data acquisition, analysis and wireless transmission, and can directly transmit the collected data to the data warehouse system through 5G and Wi-Fi.

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

[0074] (9) Mobile phone: A smart phone terminal with the function of recording sound signals.

[0075] (10) Customized APP: A mobile application software compatible with mobile phones, which has the function of real-time analysis and transmission of NVH data.

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

[0077] Depend on Figure 1 It can be seen that the data control method ① currently used in the existing technology can only transmit NVH data to a local desktop computer or the MDP system developed by the NVH department in the form of a cloud disk or USB flash drive, and then perform post-processing. The data interaction is relatively complex and the processing form is not uniform. The data control methods ②, ③ and ④ proposed in this application, while retaining the original cloud disk data transmission, add a data flow form with 5G wide area network and WiFi local area network as the main transmission method. By centrally transmitting NVH data to the NVH self-developed data warehouse system, testers can exchange data in the data warehouse system and centrally process it, thereby improving the efficiency of testing and analysis.

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

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

[0080] Specifically, Figure 2 A flowchart of a remote diagnosis and control method for NVH problems provided in an embodiment of the present application.

[0081] like Figure 2 As shown, the NVH problem remote diagnosis control method includes the following steps:

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

[0083] Specifically, embodiments of the present application can obtain current NVH issues based on user descriptions and inputs, or by using sensors and testing equipment to collect NVH data from the vehicle, thereby obtaining current NVH issues, without specific limitations herein. Furthermore, embodiments of the present application can obtain network data at the location where the current NVH issue occurs through 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, it also includes: based on the network data, determining whether the current network strength is greater than the 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 determining that the current NVH problem meets the preset scenario type matching condition, otherwise, determining that the current NVH problem does not meet the preset scenario type matching condition.

[0085] The preset intensity may be an intensity preset by those skilled in the art and is not specifically limited here.

[0086] Furthermore, the present embodiment of the application can subdivide the predefined application scenarios into seven application scenarios based on the types of NVH performance test and diagnosis business, namely vehicle and bench-level NVH performance development, factory production NVH performance monitoring, after-sales NVH performance maintenance, and NVH international business development. Among them, the predefined application scenarios are as follows: Figure 3 Shown, including:

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

[0088] Scenario 2: Real-time tracking of occasional NVH quality issues refers to the intermittent, sudden, and irregular performance characteristics of NVH issues, which require real-time monitoring by test equipment 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 problems that need to be solved in a timely manner and are raised at a test site that is far away from the R&D base.

[0090] Scenario 4: NVH performance acceptance of supplier parts refers to the supplier's test bench status. When the individual parts need to meet specific NVH indicators, corresponding data proof is required.

[0091] Scenario 5: NVH performance consistency monitoring of the production line means that when products on the production line have unstable NVH performance problems, timely monitoring is required to obtain problem data.

[0092] Scenario 6: Remote diagnosis of NVH issues arising from after-sales complaints means that when a customer or 4S shop raises a related NVH issue, a remote assistance channel needs to be established with the consumer or 4S shop.

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

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

[0095] If the current network strength is greater than the preset strength and the current NVH problem belongs to a predefined application scenario, it is determined that the current NVH problem meets the preset scenario type matching condition.

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

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

[0098] Among them, the target transmission methods include data collection and transmission methods based on a preset mobile terminal APP, data transmission methods based on a preset integrated portable data acquisition system, and data transmission methods based on a preset PC-side unified acquisition platform.

[0099] Furthermore, in some embodiments, the target transmission mode is determined according to the problem type of the current NVH problem, including: judging whether the user has a time limit requirement for the diagnosis result; if the user has a time limit requirement for the diagnosis result, then when the time limit requirement is an immediate requirement, the target transmission mode is determined to be a data transmission mode based on a preset PC-side unified acquisition platform; when the time limit requirement is a non-immediate requirement, the target transmission mode is determined to be a data transmission mode based on a preset integrated portable data acquisition system; otherwise, judging whether the problem type is a noise type; if the problem type is a noise type, the target transmission mode is a data acquisition and transmission mode based on a preset mobile terminal APP; otherwise, judging whether the problem type is a vibration monitoring type; if the problem type is a vibration monitoring type, the target transmission mode is a data transmission mode based on a preset integrated portable data acquisition system, and / or, a data transmission mode based on a preset PC-side unified acquisition platform.

[0100] The preset mobile terminal may be a mobile phone or other handheld communication device with a radio shortwave communication function, which is not specifically limited here.

[0101] Specifically, when it is determined based on the current NVH problem and / or network data that the current NVH problem meets the preset scenario type matching conditions, the corresponding application scenario in the predefined application scenarios 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, determine whether the user has a time limit requirement for the diagnosis result. If the user has a time limit requirement for the diagnosis result, then when the time limit requirement is immediate (i.e., detailed NVH problem diagnosis and conclusion output are required immediately), determine the target transmission method as a data transmission method based on the preset PC-side unified acquisition platform.

[0103] Furthermore, if the user has a time limit requirement for the diagnosis results, and the time limit requirement is non-immediate, that is, the user does not have high requirements for the immediacy of the NVH problem diagnosis results, that is, detailed problem diagnosis and conclusion output are not required 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, it is determined whether the NVH problem type is a noise type. That is, if the current NVH problem is a qualitative judgment of a noise type problem, the current problem type is determined to be a noise type, and the target transmission method is determined to be a data collection and transmission method based on a preset mobile terminal APP.

[0105] Furthermore, if the NVH problem type is not a noise type, it is determined whether the problem type is a vibration monitoring type. If the problem type is a vibration monitoring type, that is, the problem diagnosis requires monitoring of the vibration signal, then the target transmission mode is determined to be a data transmission mode based on a preset integrated portable data acquisition system, or the target transmission mode is determined to be a data transmission mode based on a preset PC-side unified acquisition platform, or the target transmission mode is determined to be a data transmission mode based on a preset integrated portable data acquisition system and a data transmission mode based on a preset PC-side unified acquisition platform.

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

[0107] Among them, the preset data warehouse system is a platform for centralized storage and management of 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 engineer experience.

[0108] Specifically, after determining the target data transmission method based on the specific type of NVH problem and user needs, the target transmission method is used to transmit the problem data of the current NVH problem to the preset data warehouse system for remote joint diagnosis using a wireless communication network, such as 5G or WiFi network. 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 diagnostic analysis of the NVH problem, the first diagnostic result of the current NVH problem is obtained.

[0109] Therefore, when diagnosing NVH problems, the handling of complex NVH problems no longer requires the use of experienced or highly technical engineers on business trips. By integrating multiple data transmission methods, data transmission can be carried out using 5G networks, WiFi networks, etc., to achieve remote joint diagnosis and improve test efficiency.

[0110] Furthermore, in some embodiments, when the problem data of the current NVH problem is transmitted to the preset data warehouse system for diagnosis according to the target transmission method, it also includes: based on the network data, judging whether the current network speed is in the preset network speed range; if the current network speed is in the preset network speed range, uploading the problem data of the current NVH problem to the preset data warehouse system in sequence, or temporarily storing the problem data of the current NVH problem in the preset test terminal in sequence, and uploading them to the preset data warehouse system after the storage is completed; if the current network speed is not in the preset network speed range, temporarily storing the problem data of the current NVH problem in the preset test terminal in sequence, and uploading them to the preset data warehouse system after the storage is completed.

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

[0112] Specifically, the embodiments of the present application can select different transmission methods according to the network speed. First, based on the network data, the current network speed of the location where the current NVH problem occurs is obtained. If the current network speed is within the preset network speed range, that is, the current network signal quality is good, the problem data of the current NVH problem is transmitted to the preset data warehouse system in real time. Alternatively, the problem data of the current NVH problem can be temporarily stored in the preset test terminal in sequence according to user needs, and uploaded to the preset data warehouse system in a unified and centralized manner 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 turn, and uploaded to the preset data warehouse system after storage, 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, it also includes: determining whether the first diagnostic result is valid; if the first diagnostic result is valid, 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, the embodiment of the present application determines whether the first diagnostic result is valid, such as whether the diagnostic result is accurate and 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, etc., the test personnel are arranged to conduct on-site testing at the place where the NVH problem occurs, and obtain the on-site test results of the current NVH problem.

[0116] Therefore, diagnosing NVH problems using the remote diagnosis and control method proposed in the embodiments of this application does not mean completely abandoning the traditional on-site diagnosis of problems by testers traveling. However, when conducting preliminary analysis of the problem, joint diagnosis based on remote data transmission should be preferred to achieve the goal of reducing costs and increasing efficiency.

[0117] Furthermore, in some embodiments, after determining that the current NVH problem does not meet the preset scenario type matching conditions, it also includes: obtaining the on-site test results of the current NVH problem, and judging 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 the preset data warehouse system for remote joint diagnosis to obtain a second diagnostic result of the current NVH problem; otherwise, a third diagnostic 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, the test engineer is given priority to go to the site to troubleshoot, diagnose and confirm the NVH problem, so as to obtain the on-site test results of the current NVH problem, and based on the complexity of the on-site test results, the severity of the problem, and whether the necessary conditions for remote joint diagnosis (such as network status, etc.) are met, further judgment is made on whether remote joint diagnosis is required. If remote joint diagnosis is required, the problem data and on-site test results are transmitted to the preset data warehouse system for remote joint diagnosis. After remote joint diagnosis, the second diagnostic result of the current NVH problem is obtained.

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

[0120] Those in this field should understand that a complete NVH test mainly consists of five major links, of which data collection and analysis, data upload, and performance diagnosis account for 85% of the working hours. According to the standard test task calculation, after using the remote testing and diagnosis system, the five major test links can improve efficiency by about 10%-20%. Taking a single new hybrid project as an example, according to the standard operating procedures, after this application is put into operation, the cumulative reduction in man-months can be 3. The use of this control method can reduce the number of business trips, and it is expected that labor efficiency will increase by about 20%, and development costs will be reduced by 20%-30%.

[0121] In order to facilitate those skilled in the art to more clearly and intuitively understand the NVH problem diagnosis method based on scenario definition and data control mode in the embodiment of the present application, the following is combined with Figure 4 Provide detailed explanation.

In this way, the problems of high time and labor costs and low efficiency of related technologies are solved. By matching the corresponding data control method according to the specific usage scenario and using the local data warehouse system for intelligent diagnosis, the efficiency of NVH problem diagnosis is improved, and cost reduction and efficiency improvement are achieved.

[0144] Furthermore, in some embodiments, when the problem data of the current NVH problem is transmitted to the 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 in the preset network speed range based on the network data; if the current network speed is in the preset network speed range, then upload the problem data of the current NVH problem to the preset data warehouse system in sequence, or temporarily store the problem data of the current NVH problem in the preset test terminal in sequence, and upload them to the preset data warehouse system after the storage is completed; if the current network speed is not in the preset network speed range, then temporarily store the problem data of the current NVH problem in the preset test terminal in sequence, and upload them to the preset data warehouse system after the storage is completed.

This solves the problems of high time and labor 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, and cost reduction and efficiency improvement are achieved.
