[0002] In the field of research and development and manufacturing of rail vehicle door systems, the existing technical solutions usually follow the traditional verification mode of "design-manufacture physical prototype-installation test". This mode requires that after the component design is completed, a physical prototype is manufactured and installed on an actual vehicle for operation test to verify whether its function, durability and safety meet the preset technical standards. However, this verification method will cause the verification cycle to lag behind and the cost to be uncontrollable.

[0003] The above defects result in high time cost and economic risk in the research and development of door systems, which becomes a key bottleneck restricting the technological innovation of the industry.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] The present invention provides a method for verifying the parameters of production components in a vehicle door system. This method can be used to verify whether the parameters of key production components in a vehicle door system to be manufactured (such as a door system for rail vehicles) meet design standards. It enables efficient and low-cost determination of whether the parameters of production components of a vehicle door system to be verified meet production standards without actual production of the system. The core of this method lies in utilizing digital twin technology for efficient and low-cost virtual verification.

[0027] Figure 1 This is one of the flowcharts illustrating the method for verifying the production component parameters of a vehicle door system provided by the present invention.

[0028] The following will combine Figure 1 The process of verifying the parameters of the production components of the vehicle door system provided by the present invention is described.

[0029] In an exemplary embodiment of the present invention, combined with Figure 1 As can be seen, the method for verifying the parameters of the production components of the door system may include steps 110 to 130, and each step will be described below.

[0030] In step 110, a twin model of the door system corresponding to the door system to be verified is constructed. The twin model of the door system includes at least an excitation model and a door mechanism model. The excitation model is used to generate excitation signals for the door mechanism model. The model parameters of the door mechanism model are mapped to the production component parameters of the door system to be verified.

[0031] In one embodiment, a high-fidelity twin model of the door system can be constructed in a computer environment based on the design drawings, material properties, assembly relationships, and other information of the door system to be verified (the specific door design of the target vehicle model). The door system to be verified can be considered a door system that has not yet entered the actual production stage.

[0032] The twin model includes at least two sub-models, including an excitation model and a door mechanism model. The excitation model is used to simulate various excitation signals applied to the door system or the door mechanism model in actual use or under specific test conditions. For example, simulate the opening and closing door action (force, speed, angle). The door mechanism model can simulate the dynamic response and internal state change of the door system under the action of excitation. The key of the model is that the model parameters (such as mass, stiffness, damping coefficient, friction coefficient, motor characteristic parameters, geometric size tolerance, etc.) are one-to-one corresponding and mapped with the actual production component parameters (such as motor characteristic parameters provided by the supplier, door leaf weight, door leaf running track, lock system compression force, etc. Parameters such as seal rubber compression and rebound coefficient) of the door system to be verified. That is, the value of a certain parameter in the model can directly represent a key characteristic parameter of the physical production component.

[0033] In an embodiment, the door system twin model can be implemented through the AMESim simulation platform. The excitation model mainly defines the instruction input information. The excitation model simulates the external instruction signal source of the door controller, which is realized by configuring the constant signal source, step signal source and other modules of the AMESim software and assigning different values. The simulated instruction signal (corresponding to the preset excitation signal) can be a digital signal, including a door release signal, a zero speed signal, and an open / close door signal.

[0034] In step 120, a preset excitation signal is initiated to the door mechanism model based on the excitation model, and production component parameters formed by the door mechanism model after receiving the preset excitation signal are collected.

[0035] In an embodiment, based on the constructed excitation model, a preset excitation signal can be initiated to the door mechanism model. The preset excitation signal can be carefully designed according to the verification target, aiming to fully stimulate and investigate the performance of the target production component. For example, in order to verify the reliability of the door lock in an emergency, the excitation model can simulate a door closing signal encountering an obstacle. In the application process, the signal encountering an obstacle can be realized by setting a large sensitive resistance value. After the door mechanism model receives the above-mentioned preset excitation signal, it will perform calculations according to its inherent physical laws and mapped production component parameters to simulate the response of the entire door system and internal components.

[0036] Further, production component parameters directly or indirectly related to the mapped production component parameters formed by the door mechanism model during the simulation response process can be collected. Taking the opening and closing excitation signal as an example, the corresponding production component parameters can include the running curve parameters of the door leaf module and / or the running parameters of the motor module.

[0037] In step 130, in the case that the production component parameters meet the preset requirements, it is determined that the production component parameters of the vehicle door system to be verified meet the production standards.

[0038] In yet another embodiment, in the case that the collected production component parameters meet all relevant preset requirements, it is determined that the corresponding production component parameters of the vehicle door system to be verified meet the production standards. This means that the simulation verification based on digital twinning indicates that the components produced using these parameters can meet the expected functional and performance requirements after being installed in a vehicle. In this embodiment, by constructing a digital twinning model and verifying in a virtual environment, the need for manufacturing physical samples and conducting physical tests is significantly reduced or even avoided. This greatly shortens the verification period (from several weeks / months to several hours / days) and saves the cost of expensive sample manufacturing, test bench construction, manual testing, and potential loss.

[0039] The present application provides a vehicle door system production component parameter verification method, which constructs a vehicle door system twinning model corresponding to the vehicle door system to be verified, wherein the vehicle door system twinning model at least includes an excitation model and a vehicle door mechanism model, the excitation model is used to form the excitation signal of the vehicle door mechanism model, and the model parameters of the vehicle door mechanism model are mapped with the production component parameters of the vehicle door system to be verified; a preset excitation signal is initiated to the vehicle door mechanism model based on the excitation model, and the production component parameters formed by the vehicle door mechanism model after receiving the preset excitation signal are collected; in the case that the production component parameters meet the preset requirements, it is determined that the production component parameters of the vehicle door system to be verified meet the production standards. By establishing a vehicle door mechanism model that is completely mapped with the physical vehicle door system to be verified, it is realized that whether the production component parameters of the vehicle door system to be verified meet the production standards can be efficiently and low-costly judged without actually producing the vehicle door system to be verified.

[0040] Figure 2 is one of the process flow diagrams provided by the present application for initiating a preset excitation signal to the vehicle door mechanism model based on the excitation model, and collecting the production component parameters formed by the vehicle door mechanism model after receiving the preset excitation signal.

[0041] The following will be combined Figure 2 The process of initiating a preset excitation signal to the vehicle door mechanism model based on the excitation model and collecting the production component parameters formed by the vehicle door mechanism model after receiving the preset excitation signal provided by the present application will be described.

[0042] In an exemplary embodiment of the present application, the vehicle door mechanism model can include a door controller module, a motor module, a transmission device module, and a door leaf module. Combined with the above Figure 2It can be known that the step of initiating the preset excitation signal to the door mechanism model based on the excitation model and collecting the production component parameters formed by the door mechanism model after receiving the preset excitation signal can include steps 210 to 240, which will be introduced respectively.

[0043] In step 210, a preset excitation signal is initiated to the door controller module based on the excitation model, and a preset instruction corresponding to the preset excitation signal is obtained based on the analysis of the preset excitation signal by the door controller module, wherein the preset excitation signal is an excitation signal for controlling the operation of the door leaf module.

[0044] In an embodiment, the door mechanism model can include the following key functional modules: The door controller module can simulate the functions of the actual vehicle door electronic control unit (ECU), receive and analyze the instruction signal, and control the downstream actuator. The internal parameters (such as signal processing algorithm, control logic parameter) of the door controller module are mapped to the production component parameters of the door controller of the vehicle door system to be verified.

[0045] The motor module can simulate the motor characteristics of the driving mechanism of the vehicle door (such as the window lifting motor, the electric door latch motor, and the electric door opening and closing motor). The model parameters (such as rated voltage / current, torque constant, winding resistance, inductance, moment of inertia, efficiency curve, temperature characteristics, etc.) of the motor module are directly mapped to the parameters of the specific motor production components used in the vehicle door system to be verified.

[0046] The transmission module can simulate the mechanical transmission mechanism (such as gear box, worm gear, connecting rod mechanism, steel wire rope / tooth fan, etc.) connecting the motor and the final load (such as window glass, door latch mechanism, door leaf). The model parameters (such as transmission ratio, gear meshing gap and friction, connecting rod size and hinge point friction, steel wire rope stiffness and efficiency, etc.) of the transmission module are directly mapped to the parameters of the specific transmission device production components used in the vehicle door system to be verified.

[0047] The door leaf module can simulate the driven final load and its kinematics / dynamics characteristics. For electric door opening and closing, it represents the mass, center of mass, moment of inertia of the entire door leaf, and the friction damping characteristics of the slide rail (these parameters map the parameters of the corresponding door leaf structure, slide rail, etc. production components).

[0048] In another embodiment, a preset excitation signal can be initiated to the door controller module based on the excitation model, wherein the excitation model generates a preset excitation signal, which is an analog signal for controlling the operation of the door leaf module. This signal is input to the door controller module. After receiving the preset excitation signal, the door controller module analyzes the signal based on the internal mapping control logic and parameters (representing the characteristics of the actual door controller hardware and software). The purpose of the analysis is to obtain a preset instruction corresponding to the intended preset excitation signal.

[0049] In step 220, the preset instruction is sent to the motor module based on the gate controller module, so that the motor module operates in a mode matching the preset instruction.

[0050] In another embodiment, the gate controller module can send the parsed preset instruction to the motor module. After receiving the preset instruction, the motor module operates in a mode matching the preset instruction based on the mapped motor production component parameters. This simulates the actual motor's response under the real control instruction.

[0051] In step 230, the transmission module is driven to operate based on the operating motor module, and the door leaf module is driven to operate based on the operating transmission, to obtain the operating curve parameters of the door leaf module.

[0052] In step 240, the operating curve parameters of the door leaf module are taken as the production component parameters, and the production component parameters are collected.

[0053] In another embodiment, the operating motor module outputs torque and rotating speed, and drives the transmission module to operate. The transmission module converts (decelerates / increases force / changes the direction of motion) and transmits the motion of the motor based on the mapped transmission component parameters (such as transmission ratio, friction, clearance), and drives the door leaf module to operate. During the entire simulation execution process (or after the end), the operating curve parameters of the door leaf module are collected. These parameters are the motion state characteristics of the door leaf module after being driven, wherein the operating curve parameters of the door leaf module can include the speed-time curve and displacement-time curve of the door leaf opening / closing. Further, the operating curve parameters of the door leaf module are taken as the production component parameters for collection.

[0054] It should be noted that although the motion curve of the door leaf is directly collected, these curves are the comprehensive results of the joint action of the gate controller module parameters, the motor module parameters, the transmission module parameters, and the door leaf module parameters, and are obtained through accurate simulation calculation by the mechanism model. They indirectly but accurately reflect the performance of these underlying production component parameters (such as motor response speed, transmission efficiency, friction damping, and load inertia).

[0055] In the application process, the collected operating curve parameters of the door leaf module can be compared with the preset requirements. If the operating curve parameters meet all the preset requirements, it is determined that the related production component parameters (related components of the gate controller, motor, transmission, and door leaf) of the to-be-verified vehicle door system participating in the control process meet the production standard.

[0056] In another exemplary embodiment of the present application, the above steps are continued Figure 2The embodiment is described by example, after the preset instruction is sent to the motor module based on the door controller module, so that the motor module operates in a mode matching the preset instruction, the vehicle door system production component parameter verification method can further include the following steps: obtaining the operating parameters of the motor module; The operating parameters of the motor module are used as production component parameters, and the production component parameters are collected.

[0057] In an embodiment, after the motor module receives the preset instruction, it operates in a mode matching the preset instruction based on the mapped motor production component parameters (for example: accelerates to the target speed and outputs the specified torque according to the instruction). After the motor module starts operating (during or after it ends), the operating parameters of the motor module can be obtained. These operating parameters are physical quantities generated by the internal calculation of the twin model, reflecting the real-time or final working state of the motor during the response to the preset instruction and the execution of the operation process. Typical motor operating parameters can include: input current waveform (instantaneous value, effective value, peak value), input voltage waveform, power consumption, winding temperature, etc. In this embodiment, the operating parameters of the motor module are not specifically limited.

[0058] Further, the operating parameters of the motor module can also be collected as production component parameters. These parameters are directly related to and reflect the inherent characteristics and performance of the actual motor production components mapped by the motor module. In the application process, if all the collected production component parameters, such as the door leaf operating curve and / or the motor operating parameters, meet the preset requirements, it can be determined that the related production component parameters (especially the motor component and its related parameters) of the vehicle door system to be verified meet the production standards.

[0059] In another embodiment, when the door leaf operating curve is not up to standard, combined with the analysis of the motor operating parameters, the problem source can be more accurately distinguished: if the door leaf operating is abnormal (such as slow speed), but the motor operating parameters are normal (such as current and torque output meet the expectation), the problem is likely to be in the transmission device or the door leaf load (mapped transmission component or door leaf component parameter problem). If the door leaf operating is abnormal, and the motor operating parameters are also abnormal (such as actual output torque is insufficient, current is too large, temperature rise is too high), the problem is likely to be in the motor itself or its control (mapped motor component parameter or door controller parameter problem).

[0060] In another example embodiment of the present application, the preset excitation signal can be a first excitation signal, and the first excitation signal can be a switch door excitation signal for controlling the door leaf module to operate under an obstacle. Continue to describe the previous embodiment, before the preset instruction corresponding to the preset excitation signal is obtained based on the analysis of the preset excitation signal by the door controller module, the method further includes: In the case that the door leaf module is detected to encounter an obstacle, the detection door controller module receives a first excitation signal to determine whether the first excitation signal is valid; In the case that the door leaf module is detected to encounter an obstacle, the detection door controller module receives a first excitation signal to determine whether the first excitation signal is valid; In the case that the door leaf module is detected to encounter an obstacle, the detection door controller module receives a first excitation signal to determine whether the first excitation signal is valid;

[0061] In an embodiment, in the case that the door leaf module is detected to encounter an obstacle, the detection door controller module receives a first excitation signal to determine whether the first excitation signal is valid. In the case that the first excitation signal is valid, the detection door controller module analyzes the first excitation signal, i.e., a switch door excitation signal for controlling the door leaf module to run in the presence of an obstacle, to obtain a preset instruction corresponding to the first excitation signal. Then, the motor module and the door leaf module can be controlled based on the preset instruction corresponding to the first excitation signal, so as to collect whether the corresponding production component parameters meet the preset requirements, and then determine whether the production component parameters of the to-be-verified vehicle door system meet the production standards.

[0062] In the case that the door leaf module is detected to encounter an obstacle, the detection door controller module receives a first excitation signal to determine whether the first excitation signal is valid; the clamping force fed back by the door leaf module is greater than a threshold, or the sensor detects an obstacle, or in the case that the displacement of the door leaf module does not change within a specified time, it is determined that there is an obstacle, and further an obstacle signal can be output to the switch door control module.

[0063] In another embodiment, in addition to the clamping force fed back by the door leaf module being greater than a threshold, or the sensor detects an obstacle, or in the case that the displacement of the door leaf module does not change within a specified time, it is further determined whether a position switch signal is a valid level, for example, a low level. If yes, it is determined that there is an obstacle, and further an obstacle signal can be output to the switch door control module. Through this embodiment, the accuracy of obstacle detection can be further ensured.

[0064] In another exemplary embodiment of the present application, the preset excitation signal can be a second excitation signal, and the second excitation signal can be a switch door excitation signal for controlling the door leaf module to run in the absence of an obstacle. Continuing to take the previously described embodiment as an example, before the step of analyzing the preset excitation signal based on the door controller module to obtain a preset instruction corresponding to the preset excitation signal, the method can further include the following steps: In the case that the door leaf module is detected not to encounter the obstacle, the detection door controller module receives the second excitation signal to determine whether the second excitation signal is valid; In the case that the door leaf module is detected not to encounter the obstacle, the detection door controller module receives the second excitation signal to determine whether the second excitation signal is valid; In the case that the door leaf module is detected not to encounter the obstacle, the detection door controller module receives the second excitation signal to determine whether the second excitation signal is valid;

[0065] In the case that the door leaf module is detected not to encounter the obstacle, the detection door controller module receives the second excitation signal to determine whether the second excitation signal is valid;

[0066] It should be noted that the detection of the door leaf module not encountering the obstacle can refer to the judgment idea of the door leaf module encountering the obstacle, which is not limited in this embodiment.

[0067] In another example embodiment of the present application, the determination of whether the first excitation signal and / or the second excitation signal received by the door controller module is valid can be achieved in the following manner: In the case that the door leaf module is detected to encounter the obstacle and the door controller module is detected to receive the door release signal and the zero speed signal, it is determined that the first excitation signal received by the door controller module is valid, wherein the door release signal is a signal for controlling the door leaf module to start running, and the zero speed signal is a signal that the running speed of the rail vehicle corresponding to the vehicle door system to be verified is zero speed, or In the case that the door leaf module is detected not to encounter the obstacle and the door controller module is detected to receive the door release signal and the zero speed signal, it is determined that the second excitation signal received by the door controller module is valid, wherein the door release signal is a signal for controlling the door leaf module to start running, and the zero speed signal is a signal that the running speed of the rail vehicle corresponding to the vehicle door system to be verified is zero speed.

[0068] In an embodiment, in the case that the door leaf module is detected to encounter the obstacle and the door controller module is detected to receive the door release signal and the zero speed signal, it is determined that the first excitation signal received by the door controller module is valid.

[0069] In yet another embodiment, in the case that the door leaf module is detected not to encounter an obstacle, and at the same time, the door operator module is detected to receive a door release signal and a zero speed signal, it can be determined that the second excitation signal received by the door operator module is valid.

[0070] In this embodiment, based on the binary judgment logic of specific scenarios (obstacle encounter / non-encounter) and specific signal combinations (door release signal + zero speed signal), the implementation of signal validity detection in the digital twin model has clear operation steps and judgment basis, ensuring the repeatability of the verification process and the clarity of the results. It should be noted that by setting the zero speed signal to determine the validity of the first and second excitation signals, it can prevent accidental touching of the door release button and the door opening button when the train is running at high speed, which may cause the train door to open unexpectedly when running at high speed.

[0071] Figure 3 is a flowchart of the process of initiating a preset excitation signal to the train door mechanism model based on the excitation model and collecting the production component parameters formed by the train door mechanism model after receiving the preset excitation signal.

[0072] The following will be described in conjunction with Figure 3 The process of initiating a preset excitation signal to the train door mechanism model based on the excitation model and collecting the production component parameters formed by the train door mechanism model after receiving the preset excitation signal will be described.

[0073] In an exemplary embodiment of the present application, the train door system twin model can further include a calibration model, wherein the calibration model is used to calibrate the model parameters of the train door mechanism model based on the production component parameters of the door leaf of the train door system under normal operation. Figure 3 It can be seen that the process of initiating a preset excitation signal to the train door mechanism model based on the excitation model and collecting the production component parameters formed by the train door mechanism model after receiving the preset excitation signal can include steps 310 and 320, which will be described below.

[0074] In step 310, the train door mechanism model is calibrated based on the calibration model to obtain a calibrated train door mechanism model; In step 320, a preset excitation signal is initiated to the calibrated train door mechanism model based on the excitation model, and the production component parameters formed by the calibrated train door mechanism model after receiving the preset excitation signal are collected.

[0075] In an embodiment, the production component parameters of the door leaf of the vehicle door system in normal operation (such as actual measured normal opening and closing speed curve, force curve, etc.) can be used as input to adjust the internal model parameters (such as friction coefficient, damping value, stiffness, etc.) of the vehicle door mechanism model through the calibration model, so that the output (simulated door leaf operation parameter) of the vehicle door mechanism model is as close as possible to the actual normal operation data, thereby obtaining the calibrated vehicle door mechanism model. It can be understood that the calibrated vehicle door mechanism model is the vehicle door mechanism model after parameter adjustment.

[0076] Further, the calibrated vehicle door mechanism model can be used as the vehicle door mechanism model. In the application process, a preset excitation signal can be initiated to the calibrated vehicle door mechanism model based on the excitation model, and the production component parameters formed by the calibrated vehicle door mechanism model after receiving the preset excitation signal can be collected. Since the subsequent excitation application and parameter collection are based on the calibrated vehicle door mechanism model with higher accuracy, the risk of distorted verification results caused by errors in the model itself is greatly reduced, making the final determination of whether the production component parameters meet the standard more accurate and reliable.

[0077] In the embodiment, the internal parameters of the vehicle door mechanism model are adjusted by the calibration model using the actual production component parameters of the door leaf in normal operation, so that the calibrated vehicle door mechanism model can more accurately simulate the real physical behavior of the vehicle door system, significantly improving the fidelity and credibility of the twin model.

[0078] Figure 4 is a flowchart of a process provided by the present application for determining whether the production component parameters of the vehicle door system to be verified meet the production standard under the condition that the production component parameters meet the preset requirements.

[0079] The following will be described in conjunction with Figure 4 The process provided by the present application for determining whether the production component parameters of the vehicle door system to be verified meet the production standard under the condition that the production component parameters meet the preset requirements will be described.

[0080] In an exemplary embodiment of the present application, the production component parameters can include operation curve parameters of the door leaf module. In conjunction with Figure 4 It can be understood that determining whether the production component parameters of the vehicle door system to be verified meet the production standard under the condition that the production component parameters meet the preset requirements can include step 410 and step 420, which will be described below.

[0081] In step 410, after the door leaf module operates a preset number of times, the operation curve parameters of the door leaf module after operating the preset number of times are obtained. In step 420, if the running curve parameters meet the preset requirements after the door module has run a preset number of times, it is determined that the production component parameters of the door system to be verified meet the production standards.

[0082] In one embodiment, before determining whether the parameters of the manufactured components meet production standards, the operating curve parameters (i.e., displacement / angle-time curve, velocity-time curve, acceleration-time curve, etc. after durability testing) of the door module can be obtained after it has run a preset number of times (e.g., simulating 1000 door opening and closing cycles or 500 window raising and lowering cycles). During application, if the operating curve parameters of the door module after running a preset number of times meet the preset requirements, it can be determined that the parameters of the manufactured components of the door system to be verified meet production standards. In this embodiment, in addition to single-run verification, a preset number of simulated run tests are also performed, extending the verification scope to the component's lifespan. By comparing the operating curve parameters before and after the durability test, the stability of the manufactured component parameters after long-term use can be directly evaluated.

[0083] As described above, this invention provides a method for verifying the production component parameters of a vehicle door system. The method constructs a twin model of the vehicle door system corresponding to the system to be verified. This twin model includes at least an excitation model and a door mechanism model. The excitation model generates excitation signals for the door mechanism model, and the model parameters of the door mechanism model are mapped to the production component parameters of the vehicle door system to be verified. Based on the excitation model, a preset excitation signal is sent to the door mechanism model, and the production component parameters generated by the door mechanism model after receiving the preset excitation signal are collected. If the production component parameters meet preset requirements, it is determined that the production component parameters of the vehicle door system to be verified conform to production standards. By establishing a door mechanism model that is completely mapped to the physical vehicle door system to be verified, this method enables efficient and low-cost determination of whether the production component parameters of the vehicle door system to be verified conform to production standards, even while the actual production of the vehicle door system to be verified is underway.
