Description

Technical Field

[0001] The invention belongs to the field of vehicle body leveling, and in particular relates to a method for switching between multiple leveling modes. Background Art

[0002] Engineering practice has found that, whether hydraulic or electromechanical, the performance of leveling will change with the change of ambient temperature, especially hydraulic leveling. Although designers have added various guarantee measures to the leveling methods used, the problem of difficulty in leveling caused by the influence of ambient temperature is still inevitable. At the same time, there are many ways to level the vehicle body, and the following four are common: according to the calculation method of the leveling control amount, it is divided into PID method and fixed value method. According to the leveling action, it is divided into only rising leveling and rising and falling leveling. The latter is rarely used because of the poor control of the lowering leveling, and the simple lowering leveling has never been used in practice. The advantages and disadvantages of the four methods have their own characteristics and cannot be generalized. The general leveling program only uses one of them. No one uses them at the same time and switches at any time according to the situation. In this way, it is inevitable that the above problems will occur due to the influence of ambient temperature.

[0003] Therefore, in order to deal with the problem of difficulty in leveling due to the influence of ambient temperature, the leveling program should include these four methods at the same time and have the ability to switch between these methods. When encountering problems, users can flexibly switch between the four methods to select the most appropriate method. However, there is currently no literature or patent related to this issue. Summary of the invention

[0006] Technical Solution

[0007] A method for switching between multiple leveling modes, characterized in that: first, the leveling program should have parameters indicating four leveling modes, and for this purpose, two flag bits are set in the leveling mode control word that determines the leveling mode: one is the leveling control amount calculation mode bit: =0 indicates the fixed value mode, =1 indicates the PID mode; the other is the leveling action lifting and lowering bit: =0 indicates only lifting and leveling, =1 indicates lifting and lowering and leveling; these two flag bits are collectively referred to as the leveling mode flag;

[0008] The leveling program contains leveling routines that can identify the leveling mode flags and execute the corresponding leveling mode, and the parameter change routines contained in it can modify these mode flags; specifically, when the leveling program executes the leveling routine, the leveling control amount is first calculated according to the two flags, and then the specific leveling action is executed; if the leveling cannot be completed normally and the leveling mode needs to be switched, the user issues an instruction to stop the current leveling, and enters the parameter change routine through the combination button operation, selects the leveling mode flag that needs to be changed, makes the change, saves the result after the change is completed, and reissues the leveling instruction, and subsequent leveling routines will be executed according to the new mode flag.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] The leveling program covers four modes. As long as the corresponding program is compiled, switching between the four modes requires the program to have parameters representing the four modes and to be able to change them online. The method of realizing online change of internal parameters through the existing leveling button combination can be used to solve this problem.

[0022] First, the leveling program should have parameters indicating four leveling modes. For this purpose, two flags are set in the leveling mode control word that determines the leveling mode: one is the leveling control amount calculation mode bit: =0 indicates the fixed value mode, =1 indicates the PID mode; the other is the leveling action lifting and lowering bit: =0 indicates only lifting and leveling, =1 indicates lifting and lowering and leveling. These two flags are collectively called the leveling mode flags.

[0023] The leveling program contains a leveling routine that can identify the leveling mode flag and execute the corresponding leveling mode, and the parameter change routine contained in it can modify these mode flags. Specifically, when the leveling program executes the leveling routine, the leveling control amount is first calculated according to the two flags, and then the specific leveling action is performed. If the leveling cannot be completed normally and the leveling mode needs to be switched, the user issues an instruction to stop the current leveling, and enters the parameter change routine through the combination button operation, selects the leveling mode flag that needs to be changed, and changes it. After the change is completed, the result is saved, and the leveling instruction is reissued. The subsequent leveling routines will be executed according to the new mode flag. The specific method contains user interactive operations, which are characterized by:

[0024] (1) Other routines part 1

[0025] ……;

[0026] (j) If the user issues a command other than leveling, go to (m+3);

[0027] (j+1) Leveling routine:

[0028] ……;

[0029] (k) calculating the leveling control amount according to the calculation method of the leveling control amount;

[0030] (k+1) According to the lifting position of the leveling action, the control amount calculated in the previous step is used to control the legs to perform leveling;

[0031] ……;

[0032] (m) If leveling is completed normally, go to (m+2);

[0033] (m+1) When the leveling mode needs to be switched, the user issues a stop command, and the leveling program executes the command and stops. Then the user enters the parameter change routine of the leveling program through the combination button, selects the leveling mode flag to be modified, and then modifies the flag. The modification result is saved, and the user re-issues the leveling command to go to (j+1);

[0034] (m+2) The user issues a stop command, and the leveling program executes the command and stops;

[0035] (m+3) Other routines 2 parts

[0036] ……;

[0037] (m+n) turns into (1).

[0038] Now combined with the embodiments and Figure 2 The present invention is further described:

[0039] Example:

[0040] The schematic diagram of the embodiment of the present invention is shown in Figure 2 .

[0041] A hydraulic leveling subsystem is difficult to level due to the softness of the vehicle body and the influence of ambient temperature. In order to prevent the situation where leveling cannot be completed, the leveling program has taken a variety of measures and designed four leveling methods: according to the calculation method of the leveling control amount, it is divided into PID method and fixed value method; according to the leveling action, it is divided into only leveling and leveling by lifting and lowering, and two corresponding control bits are set in the leveling method control word of the leveling method: the leveling control amount calculation method bit: =0 indicates fixed value method, =1 indicates PID method; the leveling action lifting and lowering bit: =0 indicates only leveling by lifting, =1 indicates leveling by lifting. These two flag bits are collectively referred to as the leveling method flag.

[0042] The leveling routines contained in the leveling program can identify these leveling mode flags and perform corresponding leveling. The leveling program also contains a parameter change routine that can modify these flags. During use, the user can terminate the leveling that cannot be completed normally, enter the parameter change routine through the combination button, select the corresponding leveling mode flag, change and save, and re-issue the leveling command to perform leveling in the new mode. The specific process involving user interaction is carried out in the following steps:

[0043] (1) Other routines part 1

[0044] ……;

[0045] (j) If the user issues a command other than leveling, go to (m+3);

[0046] (j+1) Leveling routine:

[0047] ……;

[0048] (k) Calculate the leveling control amount according to the calculation method of the leveling control amount: = 0 is given in a fixed value method, = 1 is calculated in a PID method;

[0049] (k+1) According to the lifting and lowering position of the leveling action, the control amount calculated in the previous step is used to control the legs to perform leveling: =0 controls the relevant lifting legs to lift and level, =1 controls the relevant legs to perform lifting and lowering leveling;

[0050] ……;

[0051] (m) If leveling is completed normally, go to (m+2);

[0052] (m+1) When the leveling mode needs to be switched, the user issues a stop command, and the leveling program executes the command and stops. Then the user enters the parameter change routine of the leveling program through the combination button, selects the leveling mode flag to be modified: the leveling control amount calculation mode bit or the leveling action lifting bit, and then modifies the flag, saves the modification result, and the user re-issues the leveling command to go to (j+1);

[0053] (m+2) The user issues a stop command, and the leveling program executes the command and stops;

[0054] (m+3) Other routines 2 parts

[0055] ……;

[0056] (m+n) turns into (1).

[0057] The leveling program has the above four different modes and can switch between them, which improves the functionality, reliability and adaptability of leveling.

[0058] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
