In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the related objects are in an "or" relationship.

[0047] like Figure 1 As shown, this embodiment introduces a hydraulic control debugging method, including steps 1100-1600.

[0048] Step 1100: Obtain standard values ​​and tolerances of target parameters of the boost valve, wherein the target parameters include internal parameters of the boost valve, dimensions of the fixed iron and the moving iron fitting, and dimensions of the magnetic resistance fixed iron at the coil fitting.

[0049] The boost valve in the present invention is a solenoid valve and can be applied to various electronic control systems of a vehicle.

[0050] Specifically, the internal parameters of the boost valve include the cone angle, the steel ball diameter, and the spring preload. The dimensions of the fixed iron and moving iron fitting include the fixed iron diameter, the moving iron diameter, the opening diameter, and the ejection height of the ejector rod. The magnetic resistance fixed iron dimensions of the coil fitting include the magnetic conductive surface width of the moving iron coil and the magnetic conductive surface width of the fixed iron coil.

[0051] Step 1200: Determine the maximum value and the minimum value of each target parameter according to the standard value and tolerance of the target parameter of the boost valve.

[0052] Each target parameter has a corresponding standard value and tolerance. For example, if the standard value of the steel ball diameter is 2.5mm and the tolerance is 0.2mm, then the maximum value of the steel ball diameter is 2.6mm and the minimum value of the steel ball diameter is 2.4mm.

[0053] For example, the standard value of the fixed iron diameter is 9.7mm and the tolerance is 0.4mm. Then the maximum value of the fixed iron diameter is 9.9mm and the minimum value of the fixed iron diameter is 9.5mm.

[0054] Step 1300: Calculate, according to the maximum value and the minimum value of each target parameter, a first pressure-holding capacity corresponding to the maximum value of each target parameter and a second pressure-holding capacity corresponding to the minimum value of each target parameter.

[0055] Specifically, the pressure holding capacity is calculated according to the following formula:

[0056] ;

[0057] Among them, P represents the pressure holding capacity, S 0 L is the effective area of ​​moving iron and fixed iron, 0 is the clearance between the moving iron and the fixed iron, α is the correction coefficient, F T is the spring preload, η is the magnetic flux efficiency, I is the coil current, N is the number of coil turns, μ 0 is the vacuum permeability, L 02 is the ejection height of the ejector rod, d 0 is the fixed iron diameter, w 0 is the opening diameter, D 1 is the coil diameter, w 1 D is the magnetic conductive surface width of the moving iron coil, 2 is the coil diameter, w 2 is the magnetic conductive surface width of the fixed iron coil, D 0 D is the moving iron diameter b is the diameter of the steel ball, and θ is the cone angle.

[0058] According to the calculation formula of the above pressure holding capacity, it can be known that the pressure holding capacity obtained under different target parameters is different. When calculating the pressure holding capacity, the same coil current is used.

[0059] For each target parameter, the first pressure-holding capacity is calculated when the target parameter is at its maximum value, and the second pressure-holding capacity is calculated when the target parameter is at its minimum value. For example, the maximum value of the steel ball diameter is 2.6mm, and the minimum value of the steel ball diameter is 2.4mm. The first pressure-holding capacity corresponding to the maximum value of the steel ball diameter of 2.6mm is calculated, and the second pressure-holding capacity corresponding to the minimum value of the steel ball diameter of 2.4mm is calculated. When the steel ball diameter is used as a variable for calculation, other parameters in the pressure-holding capacity calculation formula can be selected as standard values.

[0060] Similarly, for each other target parameter, the first pressure-holding capacity corresponding to the maximum value of each target parameter and the second pressure-holding capacity corresponding to the minimum value of each target parameter are calculated respectively.

[0061] Step 1400: Determine the correlation between each target parameter and the pressure maintaining capacity of the boost valve according to the maximum value, the minimum value, the first pressure maintaining capacity and the second pressure maintaining capacity of each target parameter.

[0062] When the target parameter changes, the pressure-maintaining capability of the booster valve will also change. The correlation between the target parameter and the pressure-maintaining capability of the booster valve includes positive correlation and negative correlation.

[0063] If the pressure-holding capability of the boost valve increases accordingly when the target parameter increases, it is considered that the correlation between the target parameter and the pressure-holding capability of the boost valve is positively correlated.

[0064] If the pressure-holding capability of the boost valve decreases accordingly when the target parameter increases, it is considered that the correlation between the target parameter and the pressure-holding capability of the boost valve is negatively correlated.

[0065] Step 1500: Obtain the actual pressure-maintaining capability and target pressure-maintaining capability range of the boost valve.

[0066] Step 1600: When the actual pressure-maintaining capacity of the boost valve is not within the target pressure-maintaining capacity range, the target parameters of the boost valve are adjusted according to the correlation between each target parameter and the pressure-maintaining capacity of the boost valve, so that the actual pressure-maintaining capacity of the boost valve is within the target pressure-maintaining capacity range.

[0067] After the correlation between each target parameter and the pressure-maintaining capability of the pressure-boosting valve is obtained, the pressure-maintaining capability of the pressure-boosting valve is adjusted so that the pressure-maintaining capability of the pressure-boosting valve is within the target pressure-maintaining capability range.

[0068] For example, the correlation between the steel ball diameter and the pressure holding capacity of the boost valve is negatively correlated. If the actual pressure holding capacity of the boost valve is low, the steel ball diameter can be reduced to improve the actual pressure holding capacity of the boost valve.

[0069] For another example, the correlation between the fixed iron diameter and the pressure holding capacity of the boost valve is positively correlated. If the actual pressure holding capacity of the boost valve is low, the fixed iron diameter can be increased to improve the actual pressure holding capacity of the boost valve.

[0070] It should be understood that the adjustment of the target parameters of the boost valve in the present invention refers to the adjustment during the design process of the boost valve. The present invention is mainly used to identify possible problems in the system design and propose improvement plans to optimize the consistency and performance of the boost valve.

[0071] In this embodiment, step 1400 includes steps 1410-1420.

[0072] Step 1410: If the first pressure-maintaining capability is greater than the second pressure-maintaining capability, determine that the correlation between the target parameter and the pressure-maintaining capability of the boost valve is positively correlated.

[0073] Step 1420: If the first pressure-maintaining capability is less than the second pressure-maintaining capability, determine that the correlation between the target parameter and the pressure-maintaining capability of the boost valve is negatively correlated.

[0074] In the present invention, for a single target parameter, it is considered that the change of the pressure holding capacity is also monotonous in the process of the target parameter gradually increasing from the minimum value to the maximum value. That is, in the process of the target parameter increasing from the minimum value to the maximum value, the pressure holding capacity gradually increases from a small value to a large value, or the pressure holding capacity gradually decreases from a large value to a small value.

[0075] For a certain target parameter, when the first pressure holding capacity is greater than the second pressure holding capacity, it means that the larger the value of the target parameter is, the larger the corresponding pressure holding capacity is. In this case, the correlation between the target parameter and the pressure holding capacity of the booster valve is positively correlated.

[0076] For example, for the fixed iron diameter, the maximum value of the fixed iron diameter is 9.9mm, and the corresponding first pressure holding capacity is 30MPa. The minimum value of the fixed iron diameter is 9.5mm, and the corresponding second pressure holding capacity is 28MPa. The larger the fixed iron diameter, the greater the pressure holding capacity, so the correlation between the fixed iron diameter and the pressure holding capacity of the boost valve is positively correlated.

[0077] For a certain target parameter, when the first pressure holding capacity is less than the second pressure holding capacity, it means that the larger the value of the target parameter is, the smaller the corresponding pressure holding capacity is. In this case, the correlation between the target parameter and the pressure holding capacity of the booster valve is negatively correlated.

[0078] For example, for the steel ball diameter, the maximum value of the steel ball diameter is 2.6mm, and the corresponding first pressure holding capacity is 25MPa. The minimum value of the steel ball diameter is 2.4mm, and the corresponding second pressure holding capacity is 28MPa. The larger the steel ball diameter, the smaller the pressure holding capacity, so the correlation between the steel ball diameter and the pressure holding capacity of the booster valve is negatively correlated.

[0079] In this embodiment, step 1600 includes steps 1610-1630.

[0080] Step 1610: Determine the sizing cost of each target parameter according to the manufacturing process of each component of the boost valve.

[0081] Step 1620: Determine the target parameter to be adjusted according to the size adjustment cost of each target parameter and the first pressure holding capacity and the second pressure holding capacity of each target parameter.

[0082] Step 1630: Adjust the target parameter to be adjusted according to the correlation between the target parameter to be adjusted and the pressure maintaining capability of the boost valve.

[0083] The boost valve includes a variety of parts, and the manufacturing process of each part is different, and the corresponding target parameter size adjustment cost is also different. The size adjustment cost of some target parameters is high, while the size adjustment cost of some target parameters is low. When adjusting the target parameters of the boost valve, the target parameters of the parts with low manufacturing cost can be selected for adjustment.

[0084] The target parameter to be adjusted can be only one parameter or multiple parameters. On the one hand, the cost issue needs to be considered, and on the other hand, it is necessary to consider whether the adjustment of a single parameter can achieve the target. For example, if the actual pressure holding capacity of the boost valve is tested to be low, it is necessary to increase the pressure holding capacity of the boost valve by 3MPa by adjusting the target parameters. The parameter with the lowest adjustment cost is the steel ball diameter. Since the correlation between the steel ball diameter and the pressure holding capacity of the boost valve is negatively correlated, the steel ball diameter needs to be reduced. If the pressure holding capacity of the boost valve can be increased by 3MPa before the steel ball diameter is reduced to the minimum value, then only the steel ball diameter can be adjusted. If even if the steel ball diameter is reduced to the minimum value, the pressure holding capacity of the boost valve cannot be increased by 3MPa, then other parameters need to be adjusted so that the pressure holding capacity of the boost valve reaches the target.

[0085] In this embodiment, the method further includes steps 2100-2300.

[0086] Step 2100: testing a specified number of boost valves when the tolerance distribution of components of the boost valves is different, to obtain the pressure holding capacity distribution of the boost valves corresponding to the different tolerance distributions.

[0087] Specifically, the various distributions include uniform distribution, ±3σ normal distribution, ±4σ normal distribution, and ±6σ normal distribution, where σ is the standard deviation of the normal distribution. Other distributions may also be selected according to actual conditions.

[0088] Step 2200: Determine the proportion of the pressure-maintaining capacity distribution of the booster valve corresponding to each different tolerance distribution that meets a preset standard.

[0089] Step 2300: Determine a target tolerance distribution, wherein the proportion of the pressure holding capacity distribution of the boost valve corresponding to the target tolerance distribution that meets the standard exceeds a preset threshold, and the target tolerance distribution is used to control the dimensions of components of the boost valve.

[0090] Conduct simulation tests under various tolerance distribution conditions to determine the pressure-holding capacity distribution of a specified number of booster valves. For example, Matlab can be used to simulate 1 million sets of parts for calculation and analysis to statistically analyze the pressure-holding capacity distribution of booster valves.

[0091] If under a certain tolerance distribution, the pressure-holding capacity distribution of the boost valve meets expectations, that is, the proportion that meets the standard exceeds the preset threshold, then the component dimensions of the boost valve can be controlled based on the tolerance distribution.

[0092] During the production process of products, there are usually requirements for the pass rate. For example, the pass rate exceeds 95%, or a higher pass rate is required. For the booster valve, its pressure holding capacity is an important parameter that reflects the performance of the booster valve. For example, during the production process, the pressure holding capacity of the booster valve is required to fluctuate within ±1MPa. For example, the standard value of the pressure holding capacity of the booster valve is 25MPa, so the booster valves within the range of 24MPa-26MPa are considered qualified products, and those outside this range are unqualified products. The preset threshold can be determined based on the product pass rate.

[0093] When the tolerance distribution of parts is different, it will affect the pass rate of the booster valve. Through simulation testing, the target tolerance distribution is found, and the dimensions of the booster valve parts are controlled to improve the product pass rate.

[0094] In this embodiment, the method also includes: determining the proportion of influence of each target parameter on the pressure holding capacity of the boost valve based on a first pressure holding capacity corresponding to the maximum value of each target parameter and a second pressure holding capacity corresponding to the minimum value of each target parameter; taking the target parameter with the largest proportion of influence on the pressure holding capacity of the boost valve as a key control parameter, and the key control parameter is used to guide the system design of the boost valve.

[0095] According to the first pressure holding capacity corresponding to the maximum value of each target parameter and the second pressure holding capacity corresponding to the minimum value of each target parameter, the pressure holding capacity affected by each target parameter can be calculated, that is, the absolute value of the difference between the first pressure holding capacity and the second pressure holding capacity. For example, the maximum value of the fixed iron diameter is 9.9mm, and the corresponding first pressure holding capacity is 23.5MPa. The minimum value of the fixed iron diameter is 9.5mm, and the corresponding second pressure holding capacity is 20.2MPa. Then the pressure holding capacity affected by the fixed iron diameter is 3.3MPa.

[0096] After calculating the pressure-holding capacity affected by each target parameter, calculate the sum of the pressure-holding capacities affected by all target parameters. Then determine the proportion of each target parameter's influence on the pressure-holding capacity of the boost valve, specifically the ratio of each target parameter's influence on the pressure-holding capacity of the boost valve to the sum of the pressure-holding capacities affected by all target parameters. For example, if the pressure-holding capacity affected by the fixed iron diameter is 3.3MPa, and the sum of the pressure-holding capacities affected by all target parameters is 18.6MPa, then the proportion of the influence of the fixed iron diameter on the pressure-holding capacity of the boost valve is 17.74%.

[0097] After calculating the influence of each target parameter on the pressure-holding capacity of the boost valve, find out the target parameter with the largest influence on the pressure-holding capacity of the boost valve. For example, the influence of the fixed iron diameter on the pressure-holding capacity of the boost valve is 17.74%, while the influence of other target parameters on the pressure-holding capacity of the boost valve is less than 17.74%. Then the target parameter with the largest influence on the pressure-holding capacity of the boost valve is the fixed iron diameter. In the system design process of the boost valve, it is necessary to focus on how to set the fixed iron diameter to ensure the performance of the boost valve, thereby improving the efficiency of the overall system design.
