[0048] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions 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. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0049] As Figure 1 shown, the embodiment of the present invention provides a fuel tank adjustment method, including the following steps:

[0050] S1. Obtain the tensile force data of each suspension seat of the fuel tank;

[0051] S2. Obtain the vertical movement direction of each suspension seat according to the tensile force data of each suspension seat and the preset tensile force threshold;

[0052] S3. Obtain the line operation condition data;

[0053] S4. Obtain the fuel tank adjustment data according to the line operation condition data and the preset rules;

[0054] S5. According to the vertical movement direction of each suspension seat, the fuel tank adjustment data, and the control module, displacements of each suspension seat of the fuel tank are adjusted respectively to keep the liquid level in the fuel tank stable.

[0055] In steps S1 to S2, at least 4 suspension seats are arranged in the fuel tank. By detecting the tension data of each suspension seat in the fuel tank, the vertical movement direction of each suspension seat is obtained respectively according to the judgment made based on the acquired tension data and the preset tension threshold.

[0056] In steps S3 to S4, the change of the liquid level in the fuel tank is greatly affected by the line operation conditions during vehicle driving. Therefore, it is necessary to obtain the line operation condition data of the vehicle driving, and then calculate the adjustment data of the fuel tank according to the line operation condition data and the preset calculation rules.

[0057] In step S5, the control module adjusts the displacements of each suspension seat of the fuel tank respectively according to the vertical movement direction of each suspension seat obtained in step S2 and the adjustment data of the fuel tank calculated in step S4, so as to dynamically adjust the attitude of the fuel tank during vehicle operation, thereby keeping the liquid level in the fuel tank stable.

[0058] Preferably, step S2 includes the following steps:

[0059] Judge whether the tension data of each suspension seat is greater than the preset tension threshold respectively;

[0060] If so, the vertical movement direction of the suspension seat is upward;

[0061] If not, the vertical movement direction of the suspension seat is downward.

[0062] In the actual application process, since the liquid level of the fuel tank changes with the change of the vehicle operation attitude; if the tension data of one of the suspension seats of the fuel tank is greater than the preset tension threshold, it means that more fuel has accumulated there, and this place is at a low position. It is necessary to vertically lift the height of the suspension seat at this place to make the fuel flow back; if the tension data of one of the suspension seats of the fuel tank is less than the preset tension threshold, it means that there is a lack of fuel at this place, and this place is at a high position. It is necessary to vertically lower the height of the suspension seat at this place to make the fuel flow back; the vertical movement direction of the suspension seat is judged through the tension data, and then the height of the suspension seat is adjusted, so as to realize the even distribution of the fuel in the fuel tank.

[0063] Preferably, the line operation condition data includes: curve superelevation data, gradient data, and running acceleration data.

[0064] In the actual operation process, when the vehicle runs through a curve or a slope, the fuel tank will tilt, and the internal fuel will flow to the lower position, resulting in deviation in the test of the liquid level sensor. For example, when the fuel level inside the fuel tank is low, unstable fuel suction will occur and cause the engine to stop. Therefore, it is necessary to obtain the line operation condition data of the vehicle. In this embodiment, the obtained line operation condition data includes curve superelevation data, slope data, and running acceleration data.

[0065] As Figure 2 shown, preferably, step S4 includes the following steps:

[0066] A1. Obtain the first fuel liquid level value according to the curve superelevation data;

[0067] A2. Obtain the second fuel liquid level value according to the slope data;

[0068] A3. Obtain the third fuel liquid level value according to the running acceleration data;

[0069] A4. Obtain the fuel tank adjustment data according to the first fuel liquid level value, the second fuel liquid level value, the third fuel liquid level value, and a preset rule.

[0070] In step A1, according to the curve superelevation data and in combination with the width of the fuel tank, the first fuel liquid level value in the width direction of the fuel tank caused by the curve superelevation is calculated through a formula;

[0071] The specific calculation formula is:

[0072] where W is the width of the fuel tank; h(t) is the curve superelevation; ΔH 1 is the first fuel liquid level value; 1435 is the standard gauge, with the unit of mm.

[0073] In step A2, according to the slope data and in combination with the length of the fuel tank, the second fuel liquid level value in the length direction of the fuel tank caused by the slope data is calculated through a formula;

[0074] The specific calculation formula is: ΔH 2 = i(t) × L,

[0075] where L is the length of the fuel tank; i(t) is the line slope; ΔH 2 is the second fuel liquid level value;

[0076] In step A3, according to the vehicle running acceleration and in combination with the length of the fuel tank, the second fuel liquid level value in the length direction of the fuel tank caused by the vehicle running acceleration is calculated through a formula;

[0077] The specific calculation formula is:

[0078] where a(t) is the vehicle running acceleration; L is the length of the fuel tank body; ΔH 3 is the third fuel level value; g is the acceleration due to gravity;

[0079] In step A4, according to the first fuel level value calculated in step A1, the second fuel level value calculated in step A2, and the third fuel level value calculated in step A3, the adjustment displacement of each hanger is calculated through a formula. Among them, the adjustment data of the fuel tank body is the adjustment displacement of each hanger;

[0080] The specific calculation formula is:

[0081]

[0082]

[0083]

[0084]

[0085] where S 1 、S 2 、S 3 and S 4 represent the adjustment displacements of each hanger.

[0089] The third acquisition module is used to acquire the line operation condition data;

[0090] The fourth acquisition module is used to acquire the fuel tank body adjustment data according to the line operation condition data and a preset rule;

[0091] The adjustment module is used to respectively perform displacement adjustment on each hanger of the fuel tank body according to the vertical movement direction of each hanger, the fuel tank body adjustment data, and the control module, so as to keep the liquid level in the fuel tank stable.

[0092] In the actual application process, the first acquisition module is connected to the second acquisition module; the third acquisition module is connected to the fourth acquisition module; the adjustment module is respectively connected to the second acquisition module and the fourth acquisition module; the first acquisition module sends the tensile force data of each suspension seat of the vehicle body fuel tank to the second acquisition module, and the second acquisition module respectively obtains the vertical movement direction of each suspension seat according to the tensile force data sent by the first acquisition module and a preset threshold, and sends the obtained vertical movement direction of each suspension seat to the adjustment module; the third acquisition module sends the obtained line operation condition data to the fourth acquisition module; the fourth acquisition module obtains fuel tank adjustment data according to the line operation condition data and a preset rule, and sends the fuel tank adjustment data to the adjustment module; the adjustment module respectively adjusts the displacement of each suspension seat of the fuel tank according to the vertical movement direction of each suspension seat, the fuel tank adjustment data and the control module, so as to keep the liquid level in the fuel tank stable.
