Ensuring that these buttons can work stably and efficiently during the long-term use of the vehicle has become an urgent problem to be solved in the production process.

[0003] At present, the key function detection method in the prior art usually only relies on simple resistance value or switch state to determine whether the key is working properly. Although this method can achieve functional judgment to a certain extent, its limitations are very obvious. For example, the resistance value may be affected by factors such as ambient temperature and humidity, resulting in errors in the detection results, thereby causing unstable key functions. In addition, the prior art usually only focuses on whether the key is pressed, while ignoring other performance indicators such as the response speed and accuracy of the key execution operation.

[0014] This application provides a steering wheel assembly monitoring method and system to solve the technical problem in the prior art that the key function detection relies on simple resistance values ​​or switch states, which makes it impossible to fully evaluate the key performance, further affecting the stability and reliability of the key function. The technical goal of accurately evaluating and fully monitoring the key performance is achieved, and the technical effect of improving the key response speed, accuracy and multi-functional stability is achieved.

[0015] Below, the technical solutions in the present application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. It should also be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, rather than all of them.

[0016] For example, please refer to the attached Figure 1 The present application provides a steering wheel assembly monitoring method, which is applied to a steering wheel assembly monitoring system, and specifically includes the following steps: Step 1: Activate the auxiliary tooling, and mark the steering column of the target steering wheel by using the line drawing dial in the auxiliary tooling to obtain the target positioning reference.

[0017] Specifically, the target steering wheel is the steering wheel to be monitored for assembly. Activating the auxiliary tooling means starting and using a tool or device that can provide auxiliary functions during the assembly process, such as helping with positioning or ensuring accuracy. Next, the drawing turntable in the auxiliary tooling is operated. The drawing turntable is a rotatable device whose surface may contain reference lines for calibration. By rotating the drawing turntable, the steering column of the target steering wheel can be marked for positioning, that is, the precise position of the steering column can be determined. In this way, the target positioning reference obtained becomes a reference point in the steering wheel assembly process to ensure that the assembly of the various parts of the steering wheel meets the predetermined accuracy requirements. Through a process of gradual refinement and precision calibration, an irregular object is gradually adjusted to a standard position through a series of tools to ensure high accuracy and high quality of the final product.

[0018] Step 2: Assemble the target steering wheel to the steering column based on the target positioning reference to obtain a target assembly result.

[0019] Specifically, based on the target positioning datum, assembling the target steering wheel to the steering column is a precise assembly process. The target positioning datum provides the accurate position and direction for the assembly process. In the process of assembling the target steering wheel to the steering column, it is necessary to ensure that the connection between the steering wheel and the steering column meets the design requirements based on the calibration information of the target positioning datum. The steering column is usually an important vehicle component, connecting the steering wheel and the vehicle's steering system, and it is crucial to maintain precise fit. After the assembly is completed, the target assembly result is formed, indicating that all components have been assembled correctly and accurately and meet the specified performance standards.

[0020] Step three: Read a predetermined steering wheel button monitoring strategy, and monitor the target assembly result according to the predetermined steering wheel button monitoring strategy to obtain a target monitoring record.

[0021] Specifically, read the predetermined steering wheel button monitoring strategy. The predetermined steering wheel button monitoring strategy includes requirements for the function, response, durability, etc. of each button, such as whether the button can be operated smoothly, whether the feedback is clear, etc. Next, monitor the target assembly results according to the predetermined steering wheel button monitoring strategy, which means that after completing the assembly of the steering wheel assembly, it is necessary to perform a performance check on the assembled steering wheel buttons according to these rules. For example, you can check whether the button can be triggered normally, whether it can transmit the signal correctly, etc. Finally, through these monitoring operations, the target monitoring record is obtained, which includes the performance data of each button and whether it meets the predetermined standards, to ensure the reliability and accuracy of the assembly results.

[0022] Step 4: extracting the dynamic resistance information in the target monitoring record, and determining whether the dynamic resistance information complies with a predetermined signal constraint.

[0023] Specifically, extracting dynamic resistance information from the target monitoring record refers to obtaining data related to resistance changes from the completed monitoring records, which reflects the resistance changes of the electrical signal button during operation. Dynamic resistance information refers to the real-time change of resistance value when the button is pressed or released. For example, the resistance may decrease as the button is pressed, and then return to its original value after release. Next, judging whether the dynamic resistance information meets the predetermined signal constraints means that the extracted dynamic resistance data needs to be compared with the pre-set standards to confirm whether it is within the allowable range. The predetermined signal constraints are usually set according to design requirements. For example, the resistance change should be within a certain range (such as between 10 ohms and 50 ohms). If it exceeds this range, it means that the button may have a fault or abnormal electrical performance. Ensure that the electrical performance of the button is within the expected range, thereby ensuring that the assembled steering wheel button can be used normally. Among them, the judgment method is shown in the following table:

[0024] Step 5: If the dynamic resistance information meets the predetermined signal constraint, activate the signal processor to analyze the target monitoring record to obtain the target key function.

[0025] Specifically, if the dynamic resistance information meets the predetermined signal constraints, it means that the detected resistance change information meets the preset standard range. Dynamic resistance information refers to the change of the resistance of a button or circuit over time during operation, while the predetermined signal constraint is a set allowable range or standard value of resistance change. For example, if the resistance change exceeds the predetermined signal constraint, it does not meet the predetermined signal constraint. If the dynamic resistance information meets these predetermined signal constraints, the subsequent operation will continue.

[0026] When the resistance information meets expectations, the signal processor will start working and perform data analysis on the target monitoring records. The target monitoring records usually contain various data generated by the device during operation, including resistance value, operation time and other information. By analyzing these records, the signal processor can identify the status and functional performance of the target button. For example, by analyzing the monitoring records, the signal processor can determine whether a button has been pressed and whether the corresponding function has been successfully triggered.

[0027] By analyzing the monitoring records, the specific function of the button is finally determined as the target button function. The target button function is determined by the button design and control logic. For example, a button may be used to adjust the volume, switch the vehicle mode, or open the window. By analyzing the target monitoring records, the signal processor can confirm the actual function of the button, thereby ensuring that the button function can be correctly implemented in actual operation.

[0028] Step 6: Obtain the target execution operation, and collaboratively analyze the target execution operation and the target button function to obtain target collaborative information.

[0029] Specifically, the target action is usually a function triggered by the user's intention, such as pressing a button to adjust the volume, switch the media playback mode, or adjust the air conditioning temperature. Obtaining the target action means identifying or selecting the specific action that the user needs to perform from the system, determining the user's operation intention, and preparing for subsequent processing based on this action.

[0030] Perform collaborative analysis on the target execution operation and the target button function to identify the relationship between the target execution operation and the button function. Collaborative analysis combines the button function and the execution operation to ensure that the button operation can correctly trigger the corresponding function. For example, when the user presses the volume up or down button, confirm that the function of this button is to adjust the volume, and ensure that the collaboration between the execution operation and the function is correct.

[0031] By analyzing the coordination between the target execution operation and the target key function, information about the relationship between the two is finally generated, namely the target coordination information. The target coordination information is a data set containing the correspondence between operations and functions, which helps determine the function that each key should perform in different situations.

[0032] Step 7: The target collaborative information after weighted normalization is used to obtain the target key performance index of the target assembly result.

[0033] Specifically, standardization is the process of converting different data into a unified standard so that they can be compared and analyzed on the same scale. The target collaborative information after weighted standardization is given different weights according to the importance of each factor to obtain the target key performance index of the target assembly result, which is intended to measure the performance of the key in actual operation. For example, if a key has a high performance index, it means that it performs better in all aspects and can perform functions quickly and accurately. Otherwise, it will be worse, which will help to obtain the performance of the key in the entire assembly process.

[0034] The steering wheel assembly monitoring method is applied to a steering wheel assembly monitoring system, which can achieve the technical goal of accurate evaluation and comprehensive monitoring of button performance, and achieve the technical effect of improving button response speed, accuracy and multi-functional stability.

[0035] Furthermore, the present application also includes: before assembling the target steering wheel to the steering column based on the target positioning reference to obtain the target assembly result, it also includes obtaining the positioning base in the auxiliary tooling and connecting the positioning base to the steering column through a predetermined connection method.

[0036] Specifically, the target positioning reference is a precise position point determined by auxiliary tooling. Through the target positioning reference, it can be ensured that the assembly of the target steering wheel and the steering column meets the design requirements to ensure the accuracy and correctness of the final assembly. The target steering wheel is assembled to the steering column based on the target positioning reference. Among them, the steering column is a component in the vehicle steering system that needs to be precisely docked with the steering wheel to achieve the steering function.

[0037] Next, get the positioning base in the auxiliary tooling. The positioning base is a supporting component in the assembly process. It has a specific geometry and precision, which can ensure that other components (such as steering wheels or steering columns) are accurately positioned in the correct position. The auxiliary tooling provides the required support and positioning to help the assembly process achieve high precision.

[0038] Then, the positioning base is connected to the steering column according to a predetermined connection method. The predetermined connection method may be mechanical fixation, screw connection or snap connection to engage the external spline to ensure that the connection between the auxiliary tooling and the steering column is fixed and tight. The specific method is determined according to the design requirements. Through the predetermined connection method, the positioning base can maintain a precise positional relationship with the steering column, ensuring that the components in the assembly process will not affect the final result due to loosening or displacement.

[0039] Finally, the target assembly result is obtained. The target assembly result means that all parts have been assembled according to precise steps, all connections and positioning are in place, and finally a complete assembly with performance that meets the requirements is formed, ensuring the precise docking between parts.

[0040] Furthermore, the present application also includes: extracting the electrical signal button monitoring strategy from the predetermined steering wheel button monitoring strategy; performing a performance test on the target electrical signal button in the target assembly result according to the electrical signal button monitoring strategy to obtain the dynamic resistance information; extracting the LIN signal button monitoring strategy from the predetermined steering wheel button monitoring strategy; performing a performance test on the target LIN signal button in the target assembly result according to the LIN signal button monitoring strategy to obtain data message information; synchronizing the dynamic resistance information and the data message information based on the detection timestamp to obtain the target monitoring record.

[0041] Specifically, the electric signal button monitoring strategy in the predetermined steering wheel button monitoring strategy is extracted, and the specific strategy related to the electric signal button is extracted. The electric signal button monitoring strategy includes the rules and methods for monitoring the electrical performance of the buttons on the steering wheel. For example, the electric signal button may involve detecting whether the button can transmit the electric signal normally, or whether the electrical connection of the button is stable.

[0042] According to the electric signal button monitoring strategy, the target electric signal button in the target assembly result is tested for performance and dynamic resistance information is obtained, which means that the electric signal button in the assembled steering wheel is actually tested for performance according to the above strategy. This test may include measuring the change in resistance value. Dynamic resistance information refers to the change in resistance over time or button action during button operation, ensuring that there is no unstable electric signal transmission during button operation.

[0043] Extracting the LIN signal button monitoring strategy from the predetermined steering wheel button monitoring strategy refers to extracting some strategies related to the LIN (local interconnect network) signal button from the original monitoring plan. The LIN signal button monitoring strategy is to check whether the signal transmitted through the local interconnect network meets the standard, especially the situation where the buttons on the steering wheel communicate with other vehicle systems through the LIN protocol. These buttons may be used to send or receive data messages. In this process, the performance of the LIN signal button must meet certain requirements.

[0044] After completing the assembly of the steering wheel assembly, the target LIN signal button in the target assembly result is tested for performance according to the LIN signal button monitoring strategy, that is, the LIN signal button in the assembly result is tested for function, and the data transmitted by the button through the LIN protocol is tested to see if it is accurate and complete, and the data message information is obtained. The data message information is the specific data generated during the transmission of these signals, and records the status and results of the button operation.

[0045] According to the timestamp of each test record, the dynamic resistance information and data message information are synchronized in chronological order to ensure that the data of the two can match. The timestamp refers to the specific time when the data is recorded, ensuring that different data can be correctly aligned, and finally forming a complete target monitoring record, recording all important information in the entire assembly and test process.

[0046] By performing detailed performance tests on the electrical signal buttons and LIN signal buttons of the steering wheel, it is ensured that they meet the predetermined requirements during the assembly process. By synchronizing different types of data, the target monitoring record is finally obtained, which includes not only the electrical performance data but also the effectiveness of the communication signal. Through this detailed monitoring and recording, it can be ensured that the assembled steering wheel button system can operate reliably in actual use.

[0047] Furthermore, the present application also includes: analyzing the dynamic resistance information to obtain a resistance signal time series; collecting a resistance signal time domain feature set of the resistance signal time series; collecting a resistance signal frequency domain feature set of the resistance signal frequency domain obtained by fast Fourier transforming the resistance signal time series; forming a signal feature set based on the resistance signal time domain feature set and the resistance signal frequency domain feature set; when any signal feature parameter in the signal feature set satisfies a corresponding arbitrary signal feature threshold, the dynamic resistance information complies with the predetermined signal constraint.

[0048] Specifically, analyzing dynamic resistance information to obtain resistance signal timing means extracting the sequence of resistance value changes over time by deeply analyzing the obtained resistance change data. The resistance signal timing reflects the change process of resistance over a period of time. For example, when a key is pressed, the resistance gradually decreases, and when it is released, the resistance gradually recovers. By analyzing the timing data, we can understand the dynamic change of resistance over time, providing a basis for subsequent performance evaluation.

[0049] Collecting the resistance signal time domain feature set of the resistance signal time series refers to extracting time-related feature data from the resistance signal time series. These features may include the amplitude, waveform, periodicity, etc. of the signal, which can describe the change trend of the resistance signal over time. For example, by analyzing the resistance change curve, parameters such as the resistance change rate and change amplitude can be obtained, so as to better understand the electrical characteristics during the key operation process.

[0050] The frequency domain feature set of the resistance signal obtained by collecting the resistance signal time series through fast Fourier transformation refers to the feature data extracted from the frequency domain after converting the resistance signal time series into the frequency domain signal through fast Fourier transform (FFT). The frequency domain feature reflects the energy distribution of the signal at different frequencies, which can help analyze the potential periodicity and frequency components in the resistance signal. For example, key operation may cause signal fluctuations of a certain frequency. These frequency components can be identified through FFT to further determine the stability and normality of the signal.

[0051] The signal feature set based on the resistance signal time domain feature set and the resistance signal frequency domain feature set is to combine the feature data extracted from the time domain and frequency domain to form a complete signal feature set for further analysis and judgment of the quality of the resistance signal. For example, the time domain feature may indicate the amplitude change of the signal, while the frequency domain feature can reveal the frequency characteristics of the signal. The combination of the two can provide a more accurate judgment of the signal.

[0052] When any signal characteristic parameter in the signal characteristic set meets the corresponding arbitrary signal characteristic threshold, the dynamic resistance information meets the predetermined signal constraint, that is, if any characteristic parameter (such as amplitude, frequency, etc.) in the signal characteristic set meets the predetermined standard range, then the dynamic resistance information can be considered to meet the set signal constraint. The signal characteristic threshold is pre-set and is used to determine whether the signal is within the normal range. For example, if the frequency of the signal exceeds the set maximum frequency or the amplitude exceeds the maximum tolerance value, it may indicate that there is a problem with the key.

[0053] By analyzing the dynamic resistance information in the time domain and frequency domain, the performance of the resistance signal can be comprehensively evaluated from different angles. First, the change of the resistance signal is extracted from the time domain, and then the frequency characteristics of the signal are revealed through frequency domain analysis. These features are then combined to construct a complete set of signal features. Finally, by comparing with the predetermined signal constraints, it is determined whether the signal meets the specifications, thereby determining whether the target monitoring information meets the expected requirements.

[0054] Furthermore, the present application also includes: when any signal feature parameter in the signal feature set does not satisfy the corresponding any signal feature threshold, issuing an abnormal alarm instruction, and checking and repairing the target assembly result based on the abnormal alarm instruction.

[0055] Specifically, when any signal feature parameter in the signal feature set does not meet the corresponding arbitrary signal feature threshold, it means that after analyzing the time domain and frequency domain characteristics of the resistance signal, it is found that one of the signal features (such as resistance change amplitude, frequency, etc.) does not reach the predetermined standard range. These feature thresholds are set in advance to determine whether the signal meets the requirements of normal working conditions. If the feature parameters fail to meet the threshold conditions, for example, the change in resistance value exceeds the allowable range, it will be judged as abnormal, and then an abnormal alarm instruction will be issued to remind relevant personnel of potential problems. For example, the instruction may include specific error information, equipment status, and recommended follow-up measures, so that operators can detect problems in time and take appropriate measures.

[0056] Troubleshooting and repairing the target assembly results based on abnormal alarm instructions means that after receiving the abnormal alarm instructions, the target assembly results are carefully checked to find possible fault sources and repair them. For example, by re-evaluating the assembly quality, check whether the steering wheel buttons have poor electrical connections, abnormal button functions, etc. Troubleshooting and repair may include replacing parts, adjusting components or reassembling to ensure that the steering wheel button system returns to normal working condition.

[0057] By analyzing the signal feature set and finding that a certain feature parameter does not meet the predetermined standard, an abnormal alarm is automatically triggered to remind the operator to deal with it in time. Subsequently, based on the alarm instruction, the target assembly result is checked and repaired to ensure that the assembled steering wheel button system can work normally. Through real-time monitoring and alarm mechanisms, the assembly quality can be effectively improved and subsequent problems caused by component failure can be reduced.

[0058] Furthermore, the present application also includes: performing analog-to-digital conversion processing on the first resistance signal in the resistance signal timing by the signal processor to obtain a first digital signal; when the first digital signal reaches a predetermined threshold, reverse matching the first key corresponding to the first digital signal; obtaining the first control logic corresponding to the first key, and forming the target key function based on the first control logic.

[0059] Specifically, the signal processor performs analog-to-digital conversion processing on the first resistance signal randomly extracted from the resistance signal sequence, which means that the signal processor performs digital processing on the resistance signal, converts the continuously changing resistance signal into a digital signal that can be processed by the computer, and obtains the first digital signal. The resistance signal sequence refers to the signal generated by the change of the resistance value over time, and the analog-to-digital conversion is the process of converting these analog signals into digital signals. For example, the resistance range is from 0 ohms to 50 ohms, and the signal processor converts these continuously changing analog resistance values ​​into digital signals (such as decimal values) so that the computer or other digital system can further process them.

[0060] When the first digital signal reaches a predetermined threshold, the first key corresponding to the first digital signal is reverse matched, which means that when the digital signal reaches the set standard, the signal will be recognized and matched with a specific key. Among them, the predetermined threshold is a pre-set value that represents the normal working range of the key. When the digital signal exceeds the predetermined threshold, it will be determined that the key is pressed or activated at this time. The reverse matching process refers to tracing back from the digital signal to the specific key to determine which key generated the signal, ensuring that the key action and the system feedback are accurately corresponding.

[0061] Obtaining the first control logic corresponding to the first button, and forming the target button function based on the first control logic, means obtaining the control logic of the button after the button is identified. Control logic refers to the rules or procedures related to button operations. For example, pressing a button may trigger a function such as adjusting the volume or switching the vehicle system. Forming the target button function based on the control logic means determining the actual functional performance of the button based on its definition and function. For example, a button may perform operations such as increasing the volume or switching media playback according to its control logic.

[0062] The resistor signal is converted into a digital signal through analog-to-digital conversion. After the digital signal reaches the set threshold, the corresponding key is determined to be activated. The corresponding key is found through reverse matching, and the control logic of the key is obtained, so as to finally define and execute the function of the key. Through the digitization and logic matching of the signal, it is ensured that the key operation can accurately respond and realize the predetermined function.

[0063] Furthermore, the present application also includes: identifying the data message information in the target monitoring record through the signal processor to obtain a first data message; matching the second button corresponding to the first data message, and obtaining the second control logic corresponding to the second button; adding the second control logic to the target button function.

[0064] Specifically, the signal processor identifies the data message information in the target monitoring record to obtain the first data message, which means that the signal processor extracts and identifies the message information containing useful data from the target monitoring record. A data message refers to an information unit used for transmission, including data such as the status of a button and function instructions. When the signal processor performs identification, it parses the message and converts it into usable information, for example, determining whether a button has been pressed or a certain instruction has been generated, ensuring that the information in the message can be understood by the system and further processed.

[0065] Matching the second button corresponding to the first data message and obtaining the second control logic corresponding to the second button means finding the button associated with it and obtaining the control logic of the button based on the information extracted from the data message. Each button has its own unique control logic, which defines the specific function that will be triggered when the button is pressed. For example, a button may be related to the volume increase function, and another button may be related to switching media modes. By matching the information in the data message, it is determined which button is activated and the control logic of the button is extracted for subsequent use.

[0066] Integrate the acquired control logic of the second button into the function of the target button to ensure that the function of the target button can be operated according to the set control logic. For example, if the control logic of the second button is to adjust the volume, add this function to the target button so that when the target button is pressed, the volume adjustment operation can be triggered. The function of the button is specifically defined and can be performed as expected in actual use.

[0067] The signal processor identifies the data message information from the target monitoring record and extracts the content of the first data message. Then, by matching the data message, the corresponding key is found and the control logic of the key is obtained. Finally, the control logic is integrated into the function of the target key so that the key can perform a specific operation. Through identification, matching and integration, the correct implementation of each key function is ensured.

[0068] Furthermore, the present application also includes: extracting first collaborative information from the target collaborative information, wherein the first collaborative information includes a first execution operation and a first key function; when the first execution operation and the first key function meet a predetermined function mapping constraint, calculating a first execution time difference between the first execution operation and the first key function; performing weighted calculation on the first execution time difference after standardization to obtain the target key performance index.

[0069] Specifically, randomly extracting the first collaborative information in the target collaborative information means randomly obtaining functions related to a specific key and execution operation from the target collaborative information as the first execution operation and the first key function. The first execution operation refers to the execution of an operation, such as a key being pressed or a function being activated, and the first key function is the specific function corresponding to the key, such as increasing the volume or switching modes.

[0070] When the first execution operation and the first key function meet the predetermined function mapping constraint, it means that the relationship between the execution operation and the key function is confirmed to meet the preset rules or standards. The predetermined function mapping constraint is set in advance, for example, it is stipulated that a certain key can only correspond to a specific function operation to ensure that the actual function of the key is consistent with the design requirements. If the execution operation and the key function match, then the first execution time difference between the first execution operation and the first key function is calculated, which means measuring the difference between the time when the key executes the operation and the time required for the function to actually complete. The execution time difference refers to the time interval from the activation of the key to the actual completion of the function, which is used to evaluate the speed and accuracy of the key response. For example, if the volume adjustment operation takes longer than the predetermined value after pressing the volume up button, it may mean that the response speed is slow or there is a delay.

[0071] The first execution time difference after normalization is weighted, that is, the time difference is weighted according to different importance to obtain the target key performance index.
