[0047] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0048] In a first aspect, an embodiment of the present invention provides an air spring explosion-proof method.

[0049] Figure 1 A schematic flow chart of an air spring explosion-proof method in one embodiment of the present invention is shown.

[0050] Reference Figure 1 In one embodiment, the air spring explosion-proof method comprises the following steps:

[0051] S11, obtaining a first judgment value of each air spring, wherein the first judgment value is the pressure of the air spring;

[0052] In this embodiment, the air spring is an elastic element in the air suspension system. The air suspension system adjusts its own stiffness by inflating or deflating the air spring, which controls the vibration of the vehicle body and adjusts the height of the vehicle body, thereby ensuring the operational stability and ride comfort of the vehicle while driving. The pressure of the air spring specifically refers to the gas pressure inside the air spring. Changes in vehicle load, bumpy driving of the vehicle, and the inflation or deflation of the air spring may all affect the pressure of the air spring. If the pressure of the air spring is continuously greater than the bursting pressure, the air spring is prone to bursting by high pressure, causing a safety accident. Therefore, the pressure of the air spring is an important basis for judging whether an air spring has a risk of bursting, so as to take countermeasures against the risk spring with a risk of bursting.

[0053] Figure 2 A schematic structural diagram of an air suspension system in one embodiment of the present invention is shown.

[0054] Reference Figure 2 In one embodiment, the air suspension system includes an air suspension control unit, an air suspension air supply module, an air suspension air storage unit and four air springs. The air suspension control unit is used to control the four air springs to inflate or deflate according to external instructions or internal control strategies, the air suspension air supply module is used to inflate the four air springs, and the air suspension air storage unit is used to store and provide compressed gas to the air suspension air supply module. The four air springs are respectively a left front air spring, a right front air spring, a left rear air spring and a right rear air spring. As the name implies, the left front air spring is used to adjust the distance between the left front part of the vehicle body and the left front wheel, the right front air spring is used to adjust the distance between the right front part of the vehicle body and the right front wheel, the left rear air spring is used to adjust the distance between the left rear part of the vehicle body and the left rear wheel, and the right rear air spring is used to adjust the distance between the right rear part of the vehicle body and the right rear wheel.

[0055] In this embodiment, a pressure sensor is provided in the air suspension air supply module for measuring the pressure of four air springs. Step S11 obtains a first judgment value of each air spring through the pressure sensor.

[0056] S12, determining whether each air spring is in a maximum extension state;

[0057] In this embodiment, the air spring has different bursting pressures according to the different deformation states of the air spring. Specifically, the bursting pressure of the air spring decreases with the increase of the degree of stretching, and increases with the increase of the degree of compression. When the air spring is in the maximum stretching state, affected by the structural strength of the bladder skin, the bursting pressure of the air spring is the smallest, and it is very easy to produce a risk of explosion. Therefore, whether the air spring is in the maximum stretching state is another important basis for judging whether an air spring has a risk of explosion, so as to take countermeasures against the risk spring with a risk of explosion. It can be understood that the prior art only uses the pressure of the air spring as the only basis for judgment, resulting in low reliability of the air spring explosion-proof method, and the air spring has a high risk of explosion, which is easy to cause safety accidents.

[0058] As an optional implementation, step S12 includes:

[0059] Obtaining a second judgment value of each air spring, wherein the second judgment value is a distance between a wheel corresponding to the air spring and the vehicle body;

[0060] If the second judgment value of an air spring is equal to the second preset threshold, it is determined that the air spring is in a maximum tension state.

[0061] In this embodiment, the air spring is used to adjust the distance between the corresponding wheel and the vehicle body, thereby adjusting the height of the vehicle body. When the air spring is in the maximum tension state, the distance between the wheel and the vehicle body reaches a maximum value. The second preset threshold is set according to the actual vehicle conditions and with reference to the distance between the wheel and the vehicle body when the air spring is in the maximum tension state, and the present invention does not limit this.

[0062] Continue to refer to Figure 2 In one embodiment, the air suspension system further includes four height sensors, which are a left front height sensor, a right front height sensor, a left rear height sensor, and a right rear height sensor. The left front height sensor is used to measure the distance between the left front part of the vehicle body and the left front wheel, the right front height sensor is used to measure the distance between the right front part of the vehicle body and the right front wheel, the left rear height sensor is used to measure the distance between the left rear part of the vehicle body and the left rear wheel, and the right rear height sensor is used to measure the distance between the right rear part of the vehicle body and the right rear wheel.

[0063] In this embodiment, step S12 obtains the second judgment value of each air spring through a height sensor. Specifically, the lower part of the vehicle body is provided with a fender corresponding to the wheel, and the measurement value of the height sensor is the distance between the wheel center and the corresponding fender.

[0064] S13, if an air spring is in a maximum extension state, and the first judgment value of the air spring is greater than a first preset threshold value and lasts for a preset time, then the air spring is judged to be a risk spring;

[0065] In this embodiment, the pressure of the air spring and whether the air spring is in the maximum tension state are used as the basis for judging whether the air spring has a risk of explosion, which improves the accuracy of the judgment result, thereby improving the reliability of the air spring explosion-proof method, reducing the risk of air spring explosion, and improving the safety performance of the vehicle. Specifically, when the pressure of the air spring is used as the basis for judgment, the judgment condition that needs to be met is that it is greater than the first preset threshold and lasts for a preset time. The first preset threshold is set according to the bursting pressure of the air spring when the air spring is in the maximum tension state. The continuous preset time eliminates transient interference caused by factors such as vehicle driving bumps, thereby ensuring the accuracy of the judgment result. For example, in one embodiment, the bursting pressure of the air spring when the air spring is in the maximum tension state is measured by experiment to be A, the safety factor is set to 0.8, the first preset threshold is set to 0.8A, and the preset time is set to 10 seconds.

[0066] S14. Stop inflating the risk spring.

[0067] In this embodiment, the reason why the air spring is in the maximum extension state and the pressure of the air spring is continuously greater than the first preset threshold is usually that the air spring is inflated. Therefore, after determining that an air spring is a risk spring, the response measure taken is to stop inflating the risk spring to prevent the pressure of the air spring from further increasing, resulting in a high-pressure explosion of the air spring.

[0068] Therefore, in this embodiment, the first judgment value of each air spring is obtained, wherein the first judgment value is the pressure of the air spring; it is judged whether each air spring is in the maximum tension state; if an air spring is in the maximum tension state, and the first judgment value of the air spring is greater than the first preset threshold value and lasts for a preset time, then the air spring is judged to be a risk spring; and the risk spring is stopped from being inflated. Through this embodiment, for the case where the air spring is in the maximum tension state and the bursting pressure is the minimum, it is judged whether the air spring is a risk spring by the pressure and duration conditions, and the risk spring is stopped from being inflated, thereby effectively preventing the risk spring from being exploded by high pressure. Since the deformation state of the air spring and the corresponding bursting pressure are comprehensively considered, the air spring explosion-proof method of this embodiment has high reliability, reduces the risk of air spring explosion, and improves the safety performance of the vehicle.

[0069] It is particularly noted that the air spring explosion-proof method of the present invention can be combined with the explosion-proof measures in the relevant technology to also provide explosion-proof protection for air springs in a compressed state. For example, the risk spring determined based on the judgment condition of step S13 is defined as a first type of risk spring, and a step is added: if an air spring is in a compressed state, and the first judgment value of the air spring is greater than another preset threshold, the air spring is judged to be a second type of risk spring. Among them, since the bursting pressure of the air spring decreases with the increase of the degree of stretching and increases with the increase of the degree of compression, the preset threshold is greater than the first preset threshold. For another example, a protective sleeve is provided on the outside of the air spring. When the air spring is in a compressed state, the protective sleeve is sleeved on the outside of the air spring to provide explosion-proof protection for the air spring.

[0070] Figure 3 A schematic flow chart of an air spring explosion-proof method in another embodiment of the present invention is shown.

[0071] Reference Figure 3 In one embodiment, the air spring explosion-proof method comprises the following steps:

[0072] S21, obtaining a first judgment value of each air spring, wherein the first judgment value is a pressure value of the air spring;

[0073] S22, determining whether each air spring is in a maximum extension state;

[0074] S23, if an air spring is in a maximum extension state, and the first judgment value of the air spring is greater than a first preset threshold value and lasts for a preset time, then the air spring is judged to be a risk spring;

[0075] S24, stop charging the risk spring;

[0076] In this embodiment, the analysis of steps S21 to S24 may refer to the analysis of steps S11 to S14 in the above-mentioned embodiment, and will not be elaborated here.

[0077] S25, determining whether the vehicle is on a special road surface; if the vehicle is on a special road surface, outputting a first warning prompt; if the vehicle is not on a special road surface, outputting a second warning prompt;

[0078] In this embodiment, the reasons for the existence of risk springs in the vehicle are further analyzed. Specifically, when the vehicle is on a special road surface, the air suspension system inflates the air springs according to the external instructions or internal control strategies at the time, so that the wheels corresponding to some of the air springs are suspended in the air. When the wheels corresponding to the air springs are suspended in the air, since the air springs are not subject to the load of the vehicle body, the air springs are in the maximum tension state, and continuing to inflate the air springs will cause them to be judged as risk springs. At this time, in addition to stopping the inflating of the risk springs, it is also necessary to output the first warning prompt to inform the driver that there is a risk of explosion of the air spring, and the explosion risk is caused by the suspension of the wheels due to the special road surface, and remind the driver to adjust the vehicle height after leaving the current position.

[0079] When the vehicle is not on a special road surface, if there is a risk spring, it is usually because the execution module or detection module in the air suspension system fails, causing the air spring to continue to be inflated after it is in the maximum extension state. At this time, in addition to stopping the inflation of the risk spring, it is also necessary to output a second warning prompt to inform the driver that the air spring has a risk of explosion and that the explosion risk is caused by a failure of the air suspension system, reminding the driver to inspect the air suspension system.

[0080] In one embodiment, the step of outputting a first warning prompt includes:

[0081] The driver is reminded through text on the instrument panel that "there is a risk of explosion of the air spring in the vehicle's current state. Please leave the current position before adjusting the vehicle height."

[0082] In one embodiment, the step of outputting the second warning prompt includes:

[0083] The driver is prompted through text on the instrument panel that "there is a risk of explosion of the air spring in the current state of the vehicle. Please inspect the air suspension system."

[0084] In one embodiment, if the vehicle is not on a special road surface, in addition to outputting the second warning prompt, it is also necessary to disable the air suspension system and light up the fault light on the instrument panel so that the system stores a fault code.

[0085] In one embodiment, the step of determining whether the vehicle is on a special road surface includes:

[0086] Obtaining a second judgment value of each air spring, wherein the second judgment value is a distance between a wheel corresponding to the air spring and the vehicle body;

[0087] It is determined whether the vehicle is on a special road surface based on the second determination value of each air spring.

[0088] In this embodiment, the correlation analysis of the second judgment value refers to the analysis in step S12. When the wheel corresponding to the air spring is suspended due to the influence of a special road surface, the second judgment value of each air spring has a specific rule. The rules of the second judgment values ​​of the air springs corresponding to various special roads are summarized through experiments, so that when the second judgment value of the air spring meets a certain rule, it is judged that the vehicle is on a special road surface.

[0089] In one embodiment, the step of determining whether the vehicle is on a special road surface according to the second determination value of each air spring includes:

[0090] determining a first reference spring, wherein the first reference spring is an air spring arranged side by side with the risk spring;

[0091] The third judgment value is calculated by subtracting the second judgment value of the first reference spring from the second judgment value of the risk spring;

[0092] Determine a second reference spring and a third reference spring, wherein the second reference spring is an air spring arranged diagonally with the risk spring, and the third reference spring is an air spring arranged side by side with the second reference spring;

[0093] The fourth judgment value is calculated by subtracting the second judgment value of the third reference spring from the second judgment value of the second reference spring;

[0094] If the third judgment value is greater than or equal to the third preset threshold, and the fourth judgment value is greater than or equal to the third preset threshold, it is determined that the vehicle is on the first special road surface.

[0095] In this embodiment, the air suspension system includes four air springs, wherein two air springs arranged side by side refer to two air springs corresponding to two wheels of the same axle, for example, the left front air spring and the right front air spring corresponding to the left front wheel and the right front wheel are two air springs arranged side by side. Two air springs arranged diagonally refer to two air springs corresponding to two wheels of different axles and staggered left and right, for example, the left front air spring and the right rear air spring corresponding to the left front wheel and the right rear wheel are two air springs arranged diagonally. When the vehicle is on the first special road surface, the vehicle has only one risk spring, and the other three air springs are defined as the first reference spring, the second reference spring and the third reference spring according to the side-by-side relationship and the diagonal arrangement relationship, so that the second judgment value of each air spring is substituted into the law corresponding to the first special road surface for verification, and when the second judgment value of the air spring satisfies the law, it is judged that the vehicle is on the first special road surface.

[0096] Figure 4 A schematic diagram showing a vehicle on a first special road surface in an embodiment of the present invention is shown.

[0097] Reference Figure 4, the vehicle is on the first special road surface A, which is also called a torsion road. The right rear wheel 11 is in a suspended state, and its corresponding right rear air spring is a risk spring. The second judgment value of the risk spring is L1. Specifically, L1 is the distance between the wheel center of the right rear wheel 11 and the wheel eyebrow 20. L2, L3 and L4 are similar and are not described here. The left rear air spring corresponding to the left rear wheel 12 is the first reference spring, and the second judgment value of the first reference spring is L2. The third judgment value is equal to L1-L2. The left front air spring corresponding to the left front wheel 13 is the second reference spring, and the second judgment value of the second reference spring is L3. The right front air spring corresponding to the right front wheel 14 is the third reference spring, and the second judgment value of the third reference spring is L4. The fourth judgment value is equal to L3-L4. The third preset threshold is a. At this time, L1-L2≥a, L3-L4≥a. The third preset threshold is set according to the actual situation. For example, the third preset threshold a is equal to 30 mm.

[0098] In one embodiment, the step of determining whether the vehicle is on a special road surface according to the second determination value of each air spring includes:

[0099] determining a first reference spring, wherein the first reference spring is an air spring arranged side by side with the risk spring;

[0100] The third judgment value is calculated by subtracting the second judgment value of the first reference spring from the second judgment value of the risk spring;

[0101] If the third judgment value is greater than or equal to the fourth preset threshold, it is determined that the vehicle is on the second special road surface.

[0102] In this embodiment, when the vehicle is on the second special road surface, the vehicle has only one risk spring, and the first reference spring is defined based on the side-by-side relationship, so that the second judgment values ​​of the risk spring and the first reference spring are substituted into the law corresponding to the second special road surface for verification, and when the second judgment value of the air spring satisfies the law, it is judged that the vehicle is on the second special road surface.

[0103] Figure 5 A schematic diagram showing a vehicle on a second special road surface in an embodiment of the present invention is shown.

[0104] Reference Figure 5 , the vehicle is on the second special road surface B, which is also called the extreme single-wheel curb. The right rear wheel 11 is in a suspended state, and its corresponding right rear air spring is a risk spring. The second judgment value of the risk spring is L1, and the left rear air spring corresponding to the left rear wheel 12 is the first reference spring, and the second judgment value of the first reference spring is L2. The third judgment value is equal to L1-L2. The fourth preset threshold is b. At this time, L1-L2≥b. The fourth preset threshold is set according to the actual situation. For example, the fourth preset threshold b is equal to 40 mm.

[0105] S26. Control the risk spring to deflate until the first judgment value of the risk spring is equal to a fifth preset threshold, wherein the fifth preset threshold is less than the first preset threshold.

[0106] In this embodiment, after stopping inflating the risk spring, the risk spring is further controlled to deflate, so that the pressure of the risk spring is reduced to a value less than the first preset threshold, that is, the fifth preset threshold, thereby eliminating the risk of explosion of the air spring, thereby improving the protection effect of the air spring. For example, in one embodiment, the bursting pressure of the air spring when the air spring is in the maximum tension state is measured by experiment to be A, the first preset threshold is set to 0.8A, and the fifth preset threshold is set to 0.6A.

[0107] It should be noted that, in the embodiment, when both step S25 and step S26 exist, if the vehicle is not judged on a special road surface based on the second judgment value of the air spring, step S25 and step S26 do not have a specific time sequence. If the vehicle is judged on a special road surface based on the second judgment value of the air spring, since the deflation operation may cause the second judgment value to change, step S25 needs to be performed before step S26 to ensure the accuracy of the judgment.

[0133] Furthermore, in one embodiment, the execution module is also used for:
