[0043] The first embodiment of the present application provides a method for generating an envelope of a control system, which is suitable for a manual transmission vehicle model. The control system of the manual transmission vehicle model includes a joystick, a transition mechanism and a transmission rocker arm. The tail end of the joystick is connected to a first output rod. The transition mechanism includes a second input rod and a second output rod connected to the tail end of the second input rod. The tail end of the first output rod is connected to the head end of the second input rod, and the tail end of the second output rod is connected to the head end of the transmission rocker arm. In the process of transmitting force, there will be a first drawing stroke loss between the first output rod and the second input rod, and there will be a second drawing stroke loss between the second output rod and the transmission rocker arm.

[0044] Figure 1 is a flow chart of a method for generating an envelope of a control system according to an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps:

[0045] Step S101: obtaining design input parameters of the control system and determining whether the design input parameters are reasonable according to preset logic judgment rules;

[0046] Among them, when all the data of the design input parameters meet the logical judgment rules, the design input parameters are judged to be reasonable parameters, and step S102 is executed. When any data in the design input parameters does not meet the Susonghu logical judgment rules, the design input parameters are judged to be unreasonable parameters, and the unreasonable data in the design input parameters will be marked in red to prompt the user, and return to the input parameter interface to adjust the design input parameters and re-enter them.

[0047] It should be noted that the design input parameters are customized by the design developers and input into the control system envelope generation system through the design developers. The design input parameters include joystick length, first output rod length, second input rod length, second output rod length, gearbox rocker arm length, wire drawing efficiency, first wire drawing stroke loss, second wire drawing stroke loss and gearbox rocker arm stroke under each gear. The preset logical judgment rules include multiple judgment conditions. Each data in the design input parameters is matched with a corresponding judgment condition. For example, for the joystick length, the corresponding judgment condition is that the joystick length is not less than 150mm and not more than 400mm. For the gearbox rocker arm length, the corresponding judgment condition is that the gearbox rocker arm length is not less than 30mm and not more than 200mm. For the wire drawing efficiency, the corresponding judgment condition is that the wire drawing efficiency is less than 1. For the first wire drawing stroke loss and the second wire drawing stroke loss, the two judgment conditions are the same, and specifically are greater than 0 and not more than 10mm.

[0048] Step S102: When it is determined that the design input parameters are reasonable parameters, the design input parameters are input into VB software, and the design input parameters are converted into conversion parameters through an analysis formula;

[0049] Among them, the analysis formula can be customized, and there are multiple preset analysis formulas, and different data in the conversion parameters are matched with corresponding analysis formulas. The conversion parameters include the gearbox rocker arm angle, the first output rod stroke, the second input rod stroke, the second output rod stroke, the joystick stroke and the joystick limit stroke under each gear.

[0050] Specifically, for the gearbox rocker arm angle at each gear, the corresponding analysis formula is as follows:

[0051] A j =2*sin -1 [N j / (2*L5)]

[0052] Among them, A j Represents the gearbox rocker arm angle at the jth gear, N j represents the gearbox rocker arm stroke under the j-th gear position, and L5 represents the gearbox rocker arm length.

[0053] For the second output rod stroke in each gear position, the corresponding analytical formula is as follows:

[0054] Q j =N j +δ2

[0055] Among them, Q j represents the second output rod stroke in the jth gear, N j represents the gearbox rocker arm stroke under the j-th gear position, and δ2 represents the second wire drawing stroke loss.

[0056] For the second input rod stroke in each gear position, the corresponding analytical formula is as follows:

[0057] M j =Q j *λ2

[0058] Among them, M j represents the second input rod stroke in the j-th gear position, and λ2 represents the second-stage lever ratio.

[0059] For the first output rod stroke in each gear position, the corresponding analysis formula is as follows:

[0060] O j =M j +δ1

[0061] Among them, Oj represents the first output rod stroke under the j-th gear position, M j represents the second input rod stroke at the j-th gear position, and δ1 represents the first wire drawing stroke loss.

[0062] For the limit travel of the joystick in each gear position, the corresponding analysis formula is as follows:

[0063] SS j =O j *λ1

[0064] Among them, SS j represents the limit travel of the joystick in the jth gear, λ1 represents the first-stage lever ratio, and δ represents the system travel loss.

[0065] For the joystick travel in each gear position, the corresponding analysis formula is as follows:

[0066] S j =(N j +δ)*λ1*λ2

[0067] Among them, S j is the joystick stroke in the jth gear, j = R, 1, 2, 3, ..., N j is the gearbox rocker arm stroke under the j-th gear, δ is the system stroke loss, λ1 is the first-stage lever ratio, and λ2 is the second-stage lever ratio.

[0068] Step S103, based on the design input parameters and the conversion parameters, envelope parameters are calculated using conversion rules;

[0069] Among them, the envelope parameters include the second input rod angle, the joystick angle, the first-stage leverage ratio, the second-stage leverage ratio, the total leverage ratio and the limit envelope safety factor, and the conversion rules include the stroke conversion formula, the angle conversion formula and the force conversion formula.

[0070] Specifically, the calculation formula of the limit envelope safety factor is as follows:

[0071] σ=SS j / S j

[0072] Among them, SS j is the limit travel of the joystick in the jth gear, S j is the joystick stroke at the jth gear, and σ is the limit envelope safety factor.

[0073] The calculation formula of the joystick angle at each gear position is as follows:

[0074] B j =2*sin-1 [S j / (2*L1)]

[0075] Among them, B j is the joystick angle at the jth gear, S j is the joystick stroke in the j-th gear, and L1 is the joystick length.

[0076] The calculation formula for the first-level leverage ratio is as follows:

[0077] λ1=L1 / L2

[0078] Wherein, λ1 represents the first-stage lever ratio, L1 represents the joystick length, and L3 represents the first output rod length.

[0079] The calculation formula for the second-tier leverage ratio is as follows:

[0080] λ2=L3 / L4

[0081] Wherein, λ2 represents the second stage lever ratio, L3 represents the second input rod length, and L4 represents the second output rod length.

[0082] The calculation formula of the second input rod angle is as follows:

[0083] C j =2*sin -1 [M j / (2*L3)]

[0084] Among them, C j represents the second input rod angle in the jth gear, M j represents the second input rod stroke in the j-th gear position, and L3 represents the second input rod length.

[0085] The calculation formula for selecting / shifting force in each gear is as follows:

[0086] FF j =F j / (λ1*λ2)

[0087] Among them, FF j F is the j-th gear selection / shifting force, j is the gearbox rocker arm force in the jth gear.

[0088] Step S104, diagnosing the envelope parameters using diagnostic rules to determine whether the envelope parameters meet design standards;

[0089] Among them, the diagnostic rules include multiple diagnostic statements for identifying the data in the envelope parameters one by one, and the diagnostic statements are all preset manually, that is, each data in the envelope parameters is pre-set with a corresponding diagnostic statement. For example, for the transmission rocker arm angle, the diagnostic statement is that the transmission rocker arm angle is not greater than 30°. For the selection / shift force, there are different diagnostic statements for different vehicle models. When the vehicle model is a truck, for the selection force, the diagnostic statement for the transmission rocker arm angle is that the transmission rocker arm angle is not greater than 35N, and for the shift force, the corresponding diagnostic statement is that the shift force is not greater than 50N; when the vehicle model is not a truck, for the selection force, the corresponding diagnostic statement is that the selection force is not greater than 20N, and for the shift force, the corresponding diagnostic statement is that the shift force is not greater than 28N.

[0090] It should be noted that when all the data in the envelope parameters pass the corresponding diagnostic statements, the envelope parameters are judged to meet the design standards and step S105 is executed. When any data in the included parameters does not pass the corresponding diagnostic statements, the included parameters are judged to not meet the design standards. At this time, the operating system envelope generation system will adjust the design input parameters according to the data that does not meet the design standards and issue a prompt to optimize the design input parameters.

[0091] It can be understood that the design input parameters are input into the VB software, and the optimal shift envelope data is output through algorithm iteration. This not only realizes the output of shift stroke and shift angle and supports the compilation of shift envelope, but also improves the efficiency of shift envelope output. It should be noted that the envelope data in the envelope parameters are not limited to the above-mentioned selection / shift stroke, selection / shift force, etc.

[0092] Step S105 : When the envelope parameters meet the design standards, modeling is performed based on the envelope parameters through the DMU module in CATIA software to generate a gear shift control system envelope.

[0093] Through the above steps, the design input parameters of the control system are identified through logical judgment rules to automatically identify the accuracy of the design input parameters. VB software is then used to develop the control system envelope calculation software. The design input parameters are converted into conversion parameters using analytical formulas in the VB software. Based on the conversion parameters and the design input parameters, the envelope parameters are obtained through conversion rules and presented in the form of analysis software. This improves the envelope output efficiency of the control system and is more convenient for boundary data collection. At the same time, it can also solve the problem of easy errors in logical relationships and parameter input. In addition, diagnostic rules are used to diagnose the parameters and determine whether the design meets the design standards. The envelope parameters that meet the design standards are further modeled through the DMU module in the CATIA software to support vehicle verification, which can improve the accuracy and timeliness of verification.

[0094] In some embodiments, the design input parameters include joystick length, first output rod length, second input rod length, second output rod length, transmission rocker arm length, drawing efficiency, first drawing stroke loss, second drawing stroke loss and transmission rocker arm stroke under each gear.

[0095] The design input parameters are set by design developers and input into the control system envelope generation system by the design developers.

[0096] In some embodiments, the conversion parameter includes a joystick stroke at each gear position, and the joystick stroke is matched with a corresponding analytical formula. The analytical formula for calculating the joystick stroke at each gear position is as follows:

[0097] S j =(N j +δ)*λ1*λ2

[0098] Among them, S j is the joystick travel in the jth gear, j = R, 1, 2, 3...., N j is the gearbox rocker arm stroke at the jth gear, δ is the system stroke loss, λ1 is the first-stage lever ratio, and λ2 is the second-stage lever ratio.

[0099] The conversion parameters further include the gearbox rocker arm angle, the first output rod stroke, the second input rod stroke, the second output rod stroke and the joystick limit stroke at each gear position.

[0100] In some embodiments, the envelope parameters include a first-stage leverage ratio, a second-stage leverage ratio, a total leverage ratio, a limit envelope safety factor, and a second input rod angle and an operating lever angle at each gear position.

[0101] In some embodiments, the conversion rule includes multiple calculation formulas, and each data in the envelope parameter is matched with a corresponding calculation formula. The calculation formula of the limit envelope safety factor is as follows:

[0102] σ=SS j / S j

[0103] Among them, SS j is the limit travel of the joystick in the jth gear, σ is the limit envelope safety factor;

[0104] The calculation formula of the joystick angle at each gear position is as follows:

[0105] B j =2*sin -1 [S j / (2*L1)]

[0106] Among them, B j is the joystick angle at the jth gear, S j is the joystick stroke in the j-th gear, and L1 is the length of the joystick.

[0107] In some embodiments, after obtaining the design input parameters of the control system and determining whether the design input parameters are reasonable according to a preset logic judgment rule, the method further includes:

[0108] When it is determined that the design input parameters are unreasonable, the unreasonable data in the design input parameters are marked with a red background, and the user returns to the parameter input interface.

[0109] Among them, when any data in the design input parameters does not meet the corresponding judgment conditions in the logical judgment rules, the design input parameters will be judged to be unreasonable. At this time, the system will analyze the unreasonable data to point out the unreasonable reasons and optimization methods, so that the design developers can quickly find solutions and re-enter the parameters.

[0110] It should be noted that the steps shown in the above process or the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

The design input parameters are converted into conversion parameters using analytical formulas in the VB software. Then, based on the conversion parameters and the design input parameters, the envelope parameters are obtained through conversion rules. This improves the envelope output efficiency of the control system and is more convenient for boundary data collection. At the same time, it can also solve the problem of easy errors in logical relationships and parameter input.
