[0002] Currently, the algorithms used to calculate spring force in vehicle suspension simulations primarily determine the spring force under spring hysteresis based on the length of time, and use signals from devices attached to the current spring to provide feedback on the spring's status.

[0003] The above method has great limitations. Due to the limitations of materials and physical laws, the deformation and force exhibited by the spring are non-ideal, and it is difficult to calculate the spring force in the hysteresis state in real time.

[0004] Therefore, how to accurately calculate the spring force of the spring in the hysteresis state is a technical problem that needs to be solved. Summary of the Invention

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0058] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0059] First, some of the terms involved in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0060] Cross product: The vector product, also known as the outer product or cross product in mathematics and the vector product or cross product in physics, is a binary operation performed on vectors in vector space. Unlike the dot product, its result is a vector rather than a scalar. Furthermore, the cross product of two vectors is perpendicular to the sum of the two vectors. It has a wide range of applications, often found in physics, optics, and computer graphics.

[0061] This application is applied to the scenario of spring simulation, and the specific scenario is to determine the spring force of the spring by the deformation of the spring under the hysteresis state of the spring.

[0062] However, currently, the algorithms used to calculate spring force in vehicle suspension simulations primarily determine the spring force under hysteresis based on time, using signals from devices attached to the spring to provide feedback on the spring's state. Conventional hysteresis simulations typically place an integration module in the main signal path and take the difference between the integrated and pre-integrated values, using this difference as the integral input. This structure is a time-series model, simulating hysteresis based on current signal changes. This approach has significant limitations. Due to material constraints and physical laws, the deformation and force exhibited by springs are non-ideal, making it difficult to calculate the spring force under hysteresis in real time. This can lead to logical failures in the spring force calculation, resulting in erroneous data and interruptions in the hysteresis simulation process. Furthermore, this issue involves specific spring parameter settings, making it impossible to effectively identify and filter the input deformation data. This makes it impossible to guarantee a stable simulation process and accurate results.

[0063] To this end, the present application determines whether the deformation direction of the spring to be tested has changed; when it is determined that the deformation direction of the spring to be tested has changed, the current spring parameters are calculated using a preset standard hysteresis curve expression to obtain a predicted hysteresis curve, wherein the spring parameters include the deformation amount of the spring; and the spring force of the spring to be tested in the current hysteresis state is determined by predicting the hysteresis curve. When hysteresis occurs in the spring and it is determined that the deformation direction of the spring has changed, the predicted hysteresis curve of the current spring can be determined based on the deformation amount of the spring, and the spring force of the current spring can be accurately predicted based on the size of the deformation amount, thereby achieving the effect of accurately calculating the spring force of the spring in the hysteresis state.

[0064] In the embodiment of the present application, the execution entity may be a spring force calculation device in a spring force calculation system. In actual applications, the spring force calculation device may be an electronic device such as a terminal device and a server, and no limitation is made here.

[0065] The following combination Figure 1The method for calculating the spring force in the embodiment of the present application is described in detail.

[0066] Please see Figure 1 , Figure 1 A flow chart of a method for calculating spring force provided in an embodiment of the present application is shown as follows: Figure 1 The methods shown for calculating spring force include:

[0067] Step 110: Determine whether the deformation direction of the spring to be tested changes.

[0068] Determining whether the deformation direction of the spring under test has changed includes determining whether the spring under test exhibits spring hysteresis. Spring hysteresis is a phenomenon in which the spring exhibits a non-ideal ratio between deformation and force due to material and physical limitations. In vehicle suspension simulation, the spring force directly affects the vehicle's state, thereby affecting the accuracy and precision of the simulation. Therefore, including spring hysteresis in the simulation is crucial for accurate vehicle simulation.

[0069] In some embodiments of the present application, determining whether the deformation direction of the spring to be tested has changed includes: recording the current change trend of the spring to be tested and the keyword corresponding to the change trend; determining whether the keyword meets the trigger condition, wherein if the keyword meets the trigger condition, it is determined that the deformation direction of the spring to be tested has changed; if the keyword does not meet the trigger condition, it is determined that the deformation direction of the spring to be tested has not changed.

[0070] In the above process, when the spring changes, the present application can accurately determine whether the deformation direction of the spring has changed by recording the keywords corresponding to the trend of the change.

[0071] Among them, the change trend includes compression and relaxation. The keywords corresponding to the change trend can be key parameter information, such as time and deformation, or key deformation direction information. For example, when it is determined that the spring is transformed from a compression trend to a relaxation trend (or vice versa), it can be determined that the deformation direction has changed.

[0072] Step 120: When it is determined that the deformation direction of the spring to be tested has changed, current spring parameters are calculated using a preset standard hysteresis curve expression to obtain a predicted hysteresis curve.

[0073] Among them, the spring parameters include the deformation of the spring, as well as the duration of the spring hysteresis phenomenon. The preset standard hysteresis expression is a non-time domain replacement of the expression in the time domain. The modeling of the hysteresis phenomenon in the conventional time domain includes a standard time length t. This standard time length can be replaced by a standard constant s, which determines the intensity of the hysteresis phenomenon (the larger the stronger). The non-time domain expression after replacement is the standard hysteresis curve expression preset in the application.

[0074] In some embodiments of the present application, the current spring parameters are calculated using a preset standard hysteresis curve expression to obtain a predicted hysteresis curve, including: determining a two-dimensional transformation matrix using the current deformation of the spring to be measured and the spring parameters set by the user, wherein the parameters of the two-dimensional transformation matrix include multiple deformation directions and multiple deformation ratios corresponding to the multiple deformation directions; and cross-multiplying the two-dimensional transformation matrix by a preset standard hysteresis curve expression to obtain a predicted hysteresis curve.

[0075] In the above process of the present application, the predicted hysteresis curve obtained through the two-dimensional matrix can accurately predict the spring force of the spring according to the deformation of the spring at this time.

[0076] Among them, combining the current spring deformation and the slope of the curve corresponding to the spring deformation at the point of the compression (tension) curve set by the user, calculating the parameters of the two-dimensional transformation matrix (for example, 2×2), including the scaling in the x-direction and y-direction and the displacement in the y-direction, a predicted hysteresis curve can be obtained.

[0077] Step 130: Determine the spring force of the spring under the current hysteresis state by predicting the hysteresis curve.

[0078] The spring force of the spring to be tested in the current hysteresis state is determined by predicting the hysteresis curve, including obtaining the corresponding deformation from the predicted hysteresis curve according to the current spring deformation magnitude and deformation direction.

[0079] In some embodiments of the present application, the spring force of the spring to be tested in the current hysteresis state is determined by predicting the hysteresis curve, including: determining the deformation of the spring to be tested in the current state; and determining the spring force of the spring to be tested in the current hysteresis state from the predicted hysteresis curve based on the deformation.

[0080] In the above process, the present application can directly obtain the spring force corresponding to the current deformation magnitude from the predicted hysteresis curve through the current spring deformation magnitude, thereby achieving the effect of accurately predicting the spring force.

[0081] In some embodiments of the present application, after determining the spring force of the spring to be tested in the current hysteresis state by predicting the hysteresis curve, Figure 1 The method shown also includes: when it is determined that the deformation direction of the spring to be tested has not changed, calculating the spring parameters of the spring to be tested in the current state through a standard linear expression or matching the spring force corresponding to the spring parameters in the spring force table according to the spring parameters to obtain the current spring force of the spring to be tested in the normal state.

[0082] In the above process, when the deformation direction of the spring does not change, the spring force at this time can be directly calculated according to the standard linear expression, or the spring force of the current spring can be directly obtained from the table, which reduces the time used in the calculation process.

[0083] In some embodiments of the present application, when a spring is applied to a vehicle, after determining the spring force of the spring under the current hysteresis state by predicting the hysteresis curve, Figure 1 The method shown also includes: correcting the spring force in real time according to the motion state of the vehicle to obtain a final predicted spring force.

[0084] In the above process, when the spring force of the spring is predicted, the spring force can be further corrected according to the influence of the vehicle's operating state on the spring, so that the final predicted spring force is more accurate.

[0085] The vehicle's motion state may be acceleration, deceleration, or a constant speed. By comparing the effect of the current motion state and the initial motion state on the spring, the predicted spring force of the spring can be further corrected to obtain the final spring force.

[0086] In the above Figure 1 In the process shown, the present application determines whether the deformation direction of the spring to be tested has changed; when it is determined that the deformation direction of the spring to be tested has changed, the current spring parameters are calculated using a preset standard hysteresis curve expression to obtain a predicted hysteresis curve, wherein the spring parameters include the deformation amount of the spring; and the spring force of the spring to be tested in the current hysteresis state is determined by predicting the hysteresis curve. When the spring undergoes hysteresis and it is determined that the deformation direction of the spring has changed, the predicted hysteresis curve of the current spring can be determined based on the deformation amount of the spring, and the spring force of the current spring can be accurately predicted based on the size of the deformation amount, thereby achieving the effect of accurately calculating the spring force of the spring in the hysteresis state.

[0087] Previous article passed Figure 1 The method for calculating spring force is described below. Figure 2 Describe the system for calculating spring forces.

[0088] The following combination Figure 2 The system for calculating spring force according to an embodiment of the present application is described in detail.

[0089] Please see Figure 2 , Figure 2 A schematic diagram of a system for calculating spring force provided in an embodiment of the present application is shown in FIG. Figure 2 The system shown for calculating spring force consists of:

[0090] Spring state recording module, spring input parameter preprocessing module, hysteresis curve transformation matrix module and spring initial offset correction module.

[0091] Spring status recording module: used to record the change trend of the current spring to be tested and the keywords corresponding to the change trend.

[0092] Spring input parameter preprocessing module: used to determine whether the keyword meets the trigger conditions.

[0093] Hysteresis curve transformation matrix module: It is used to calculate the current deformation and curve slope of the spring to be tested using the preset standard hysteresis curve expression to obtain a two-dimensional transformation matrix.

[0094] Spring initial offset correction module: used to correct the spring force in real time according to the vehicle's motion state to obtain the final predicted spring force.

[0095] Among them, the spring input parameter preprocessing module sends the deformation of the current spring to the hysteresis curve transformation matrix module when it is determined that the keyword meets the trigger condition. The hysteresis curve transformation matrix module predicts the spring force in the current spring hysteresis state through the two-dimensional transformation matrix. When it is determined that the keyword does not meet the trigger condition, the spring force in the hysteresis state is directly sent to the spring initial offset correction module through a standard linear expression or table lookup. The spring state recording module is used to record relevant information at the transition moment of the spring change trend state, including the deformation of the spring at the current and previous moments during the discrete simulation process (the change relative to the initial state is distinguished by positive and negative, positive for tension, and negative for compression). The hysteresis curve transformation matrix module can obtain the spring force that meets the user-set parameters through the two-dimensional transformation matrix and the spring deformation.
