It is to be understood that the same or equivalent parts are designated by the same reference numerals, and different or equivalent parts are designated by different reference numerals.

[0039] The embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0040] Reference Figure 1 , Figure 1 A vehicle push rod displacement interconnection method flow chart provided by the present application is shown in FIG. 1. As shown in FIG. 1, the method comprises the steps of: Figure 1

[0041] Step S101: Calculate the push rod displacement change capability limit ratio based on the sum of the push rod displacement change capability limit and the overall machine displacement change capability limit.

[0042] Specifically, the overall machine displacement change capability limit is calculated based on the push rod displacement change capability limit. The overall machine displacement change capability limit is equal to the sum of the push rod displacement change capability limit. The calculation formula of the overall machine displacement change capability limit is: wherein, ΔS allmax is the overall machine displacement change capability limit; ΔSmax i is the i-th push rod displacement change capability limit, the bench test parameter; n is the total number of push rods.

[0043] Further, ΔSmax i is the maximum value of displacement change per unit time.

[0044] The push rod displacement change capability limit ratio is calculated based on the push rod displacement change capability limit and the overall machine displacement change capability limit. The push rod displacement change capability limit ratio is equal to the push rod displacement change capability limit divided by the overall machine displacement change capability limit. The calculation formula of the push rod displacement change capability limit ratio is: according to the formula: The push rod displacement change capability limit ratio is calculated, wherein ΔS allmax ​ΔSmax i is the displacement target difference of the i-th push rod.

[0045] Step S102: Calculate the displacement target difference of each push rod and the absolute total sum of displacement change of the whole machine, and calculate the displacement target proportion of each push rod through the displacement target difference and the absolute total sum of displacement change.

[0046] Specifically, the displacement target difference of each push rod is calculated based on the target displacement of each push rod and the executed displacement of each push rod, and the absolute total sum of displacement change of the whole machine is calculated through the displacement target difference of each push rod;

[0047] According to the formula: Calculate the displacement target proportion of each push rod, where Δδ i is the displacement target proportion of the i-th push rod, ΔS i is the displacement target difference of the i-th push rod, ΔS all is the absolute total sum of displacement change of the whole machine.

[0048] For convenience of understanding and specific description, the displacement target difference of each push rod is calculated based on the target displacement of each push rod and the executed displacement of each push rod. The displacement target difference of each push rod is equal to the target displacement of each push rod minus the executed displacement of its push rod. The calculation formula of the displacement target difference of each push rod is: i i -S(K-1) i , where Starget i is the target displacement of the i-th push rod, which is calculated by other algorithms or rules; S(K-1) i is the executed displacement of the i-th push rod, and the initial value is 0; ΔS i is the displacement target difference of the i-th push rod.

[0049] The absolute total sum of displacement change of the whole machine is calculated based on the displacement target difference of each push rod. The absolute total sum of displacement change of the whole machine is equal to the sum of the absolute values of the displacement target difference of each push rod. The calculation formula of the absolute total sum of displacement change of the whole machine is: all where ΔS all is the absolute total sum of displacement change of the whole machine.

[0050] The displacement target proportion of each push rod is calculated based on the displacement target difference of each push rod and the absolute total sum of displacement change of the whole machine. The displacement target proportion of each push rod is equal to the displacement target difference of its push rod divided by the absolute total sum of displacement change of the whole machine. The calculation formula of the displacement target proportion of each push rod is: i where Δδ i is the displacement target proportion of the i-th push rod.

[0051] Step S103: calculating each push rod displacement relative ratio based on the each push rod displacement change ability limit ratio and the each push rod displacement target ratio, and calculating each push rod displacement utilization ratio based on the each push rod displacement relative ratio and the each push rod displacement target ratio.

[0052] Specifically, each push rod displacement relative ratio is calculated based on the each push rod displacement change ability limit ratio and the each push rod displacement target ratio. The each push rod displacement relative ratio is equal to the absolute value of the each push rod displacement change ability limit ratio divided by the each push rod displacement target ratio. The calculation formula of the each push rod displacement relative ratio is: wherein, βi i is the i-th push rod relative ratio. The machine displacement reference relative ratio is obtained based on the each push rod displacement relative ratio. The machine displacement reference relative ratio is equal to the minimum value in the each push rod displacement relative ratio (the minimum value is selected to limit the push rod displacement change ability and avoid damage of the push rod caused by intense work of the push rod). The calculation formula of the machine displacement reference relative ratio is: βC=min 1≤i≤n β i wherein, βC is the machine displacement reference relative ratio.

[0053] The each push rod displacement utilization ratio is calculated based on the machine displacement reference relative ratio and the each push rod displacement target ratio. The each push rod displacement utilization ratio is equal to the machine displacement reference relative ratio multiplied by the each push rod displacement target ratio. The calculation formula of the each push rod displacement utilization ratio is: Δδ1 i = βC*Δδ i wherein, Δδ1 i is the i-th push rod displacement utilization ratio.

[0054] Step S104: calculating each push rod displacement change execution value based on the calculated machine displacement change reference value and the each push rod displacement utilization ratio, and calculating each push rod current state execution displacement based on the each push rod displacement change execution value and each push rod executed displacement, and performing to make the each push rod current state execution displacement to the target displacement of the push rod require the same time.

[0055] Specifically, the machine displacement change reference value is calculated based on the machine displacement change ability limit sum and the absolute sum of the displacement change of the machine. The machine displacement change reference value is equal to the smaller value of the machine displacement change ability limit sum and the absolute sum of the displacement change of the machine. The calculation formula of the machine displacement change reference value is: ΔS1=min(ΔS all ,ΔS allmax ), wherein, ΔS1 is the machine displacement change reference value. The each push rod displacement change execution value is calculated based on the machine displacement change reference value and the each push rod displacement utilization ratio. The each push rod displacement change execution value is equal to the product of the machine displacement change reference value and the each push rod displacement utilization ratio. The calculation formula of the each push rod displacement change execution value is: ΔS1 i = ΔS1*Δδ1i wherein, ΔS1 i is the i-th push rod displacement change execution value (it can be understood as the change amount of each push rod), and the current state execution displacement of each push rod is calculated based on the push rod displacement change execution value and the executed displacement of each push rod. The current state execution displacement of each push rod is equal to the push rod displacement change execution value plus the executed displacement of each push rod. The calculation formula of the current state execution displacement of each push rod is: S(K) i = S(K-1) i + ΔS1 i wherein, S(K) i is the i-th push rod current state execution displacement.

[0056] In an embodiment, the time required for the current state execution displacement of each push rod to change to the target displacement of the push rod is calculated according to the formula: to verify whether each push rod is associated with each other, wherein, time i is the time required for the i-th current state execution displacement to change to the target displacement of the push rod, and ΔS i is the displacement target difference of the i-th push rod.

[0057] It can be understood that, through the time i verification, it can be known that the time required for the current state execution displacement of each push rod to change to the target displacement of the push rod is a same number, that is, the time required for the current state execution displacement of each push rod to change to the target displacement of the push rod is the same, which ensures that the push rod displacement change process is associated with each other and coordinated with each other, and ensures the timeliness of the system work.

[0058] Specifically, the time i verification process is as follows:

[0059] Further, S(K) i and S(K-1) i are the execution displacements of adjacent time points.

[0060] Further, after a unit of time, step 1 is jumped to for cyclic execution.

[0061] Further, it can be known that the time required for the current state execution displacement of each push rod to change to the target displacement of the push rod is: wherein, time i is the time required for the i-th current state execution displacement to change to the target displacement of the push rod.

[0062] Further, it can be known that:

[0063]

[0064] Further, it can be known that:

[0065]

[0066] Further, it can be simplified as:

[0067]

[0068] Further, it can be simplified as:

[0069]

[0070] The above verification can know that the time required for each push rod to change its current state to its target displacement is the same, which ensures that the push rod displacement change process is correlated and coordinated with each other, and ensures the timeliness of the system work.

[0071] In an embodiment, it is judged whether the push rod displacement change execution value is less than or equal to its push rod displacement change capability limit, to verify whether the push rod is damaged. The specific verification process is as follows:

[0072] |ΔS1 i |≤S allmax *|Δδ1 i |

[0073] Further, it can be simplified as:

[0074] |ΔS1 i |≤S allmax *|βC*Δδ i |

[0075] Further, it can be simplified as:

[0076] |ΔS1 i |≤S allmax *β i *|Δδ i |

[0077] Further, it can be simplified as:

[0078]

[0079] Further, it can be simplified as:

[0080] |ΔS1 i |≤S allmax *Δτmax i

[0081] Further, according to the ratio of the displacement change capability limit of each push rod, that is, the formula: It can be known that:

[0082] |ΔS1 i |≤ΔSmax i

[0083] From the above verification, the push rod displacement change execution value is less than or equal to the push rod displacement change capacity limit, avoiding the problem of push rod damage caused by severe push rod work.

[0084] In summary, the present application calculates the current state execution displacement of each push rod, so that the current state execution displacement of each push rod changes to the target displacement of the push rod at the same time, ensuring that the push rod displacement change process is correlated and coordinated with each other, ensuring the consistency of system working efficiency. At the same time, the beneficial effect is that the push rod displacement change execution value is less than or equal to the push rod displacement change capacity limit, avoiding the problem of push rod damage caused by severe push rod work. In addition, it needs to be explained why the required time of each push rod can be the same, which is because the current state execution displacement of each push rod is calculated, for example, the execution displacement of push rod A to the target displacement (1m) is 0.3m (the actual A has already executed 0.7 displacement, and it is calculated that only 0.3 displacement needs to be executed), and the execution displacement of push rod B to the target displacement is 0.6 (that is, it has already executed 0.4, and it is calculated that 0.6 needs to be executed to 1m), thereby ensuring that the current state execution displacement of each push rod changes to the target displacement of the push rod at the same time, ensuring that the push rod displacement change process is correlated and coordinated with each other, ensuring the consistency of system working efficiency
