[0047] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the accompanying drawings. Detailed Embodiments

[0048] 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.

[0049] In a first aspect, an embodiment of the present invention provides an air spring control method.

[0050] To more clearly show the air spring control method provided by the embodiments of the present application, first, the application scenario of the air spring control method provided by the embodiments of the present application will be introduced.

[0051] The air spring control method provided by the embodiments of the present application is applied to the situation where due to the complexity of the vehicle operating conditions and some unreasonable driving operations, such as operating the air spring to lower, the vehicle chassis or body has bottomed out, but the target height has not been reached yet, which will cause the air spring to continuously deflate, and there will be a situation where the gas in the air spring is less or exhausted. If the pressure in the air storage tank is low at this time, the air spring cannot be inflated, and when the vehicle encounters complex road conditions again, it is easy to cause damage to the airbag or shock absorber block of the air spring.

[0052] In one embodiment, referring to Figure 1 , Figure 1 is a flowchart of an embodiment of the air spring control method of the present invention. As shown in Figure 1 , the air spring control method includes:

[0053] Step S10, detecting whether the vehicle frequently switches driving modes.

[0054] In this embodiment, frequent switching of driving modes generally refers to the driver performing multiple switching operations of driving modes through the IVI (In-Vehicle Infotainment, in-vehicle information entertainment system, abbreviated as IVI) within a short time interval. It should be noted that for the present invention, it is necessary to ensure that the ASC (Active Stability Control, active stability control system) is free of faults and can operate normally to avoid the failure of the height sensor and air pump of the ASC, etc., resulting in the inability to adjust the height of the air spring.

[0055] Step S20, if so, detect whether only the air storage tank is used to inflate the air spring.

[0056] In this embodiment, if it is detected that the vehicle frequently switches driving modes, then further detect whether only the air storage tank is used to inflate the air spring. It should be noted that the methods of inflating the air spring mainly include using only the air storage tank, using only the air pump, and using a combination of the air storage tank and the air pump. Among them, using the air pump to inflate the air spring with external gas has the slowest speed, which is mainly applied when there is less gas in the air spring; using the gas inside the air storage tank to inflate the air spring has the fastest speed, which is mainly applied when there is sufficient gas in the air spring.

[0057] Step S30, if so, count the inflation duration of using only the air storage tank to inflate the air spring.

[0058] In this embodiment, if it is detected that the vehicle frequently switches driving modes and further detected that only the air storage tank is used to inflate the air spring, then count the inflation duration of using only the air storage tank to inflate the air spring. The purpose is to avoid inflating the air spring with only the air storage tank for a long time, resulting in a low pressure in the air storage tank. If the pressure in the air storage tank is low, the air spring cannot be inflated, and when the vehicle encounters complex road conditions again, it is easy to cause damage to the airbag or shock absorber block of the air spring.

[0059] Step S40, when the inflation duration is greater than the preset inflation duration, it is identified as entering the underpressure mode of the air storage tank.

[0060] In this embodiment, when the inflation duration of using only the air storage tank to inflate the air spring is greater than the preset inflation duration, for example, 7 seconds, it is identified that the underpressure mode of the air storage tank is entered at this time, that is, the pressure in the air storage tank is in a low state at this time.

[0061] Step S50, disable the air spring and give a reminder of entering the underpressure mode of the air storage tank.

[0062] In this embodiment, when the pressure of the air storage tank is relatively low, it is unable to continue inflating the air spring. If the air spring is continuously used in complex road conditions, it is likely to cause damage to the air spring. At the same time, underpressure warnings for the air storage tank are given through means such as lights, voice, and instrument panels. For example, warnings like "Entering the underpressure mode of the air storage tank, the air spring is temporarily unavailable. Do not frequently switch the driving mode" can be given, which can avoid further reduction of the pressure of the air storage tank caused by frequent switching of the driving mode and reduce the damage to the air spring.

[0063] In this embodiment, when the driver performs multiple switching operations of the driving mode through the IVI within a short time interval, the duration of inflating the air spring only using the air storage tank is counted to avoid inflating the air spring only using the air storage tank for a long time, resulting in a relatively low pressure of the air storage tank. After exceeding the preset duration, it is identified as entering the underpressure mode of the air storage tank, indicating that the pressure of the air storage tank is in a relatively low state at this time. Then the air spring is disabled, which can avoid the situation that the air storage tank cannot inflate the air spring under the underpressure state of the air storage tank. If the air spring is continuously used in complex road conditions, it is likely to cause damage to the air spring. At the same time, underpressure warnings for the air storage tank are given, such as warnings like "Entering the underpressure mode of the air storage tank, the air spring is temporarily unavailable. Do not frequently switch the driving mode", which can avoid further reduction of the pressure of the air storage tank caused by frequent switching of the driving mode and reduce the damage to the air spring.

[0064] Further, in one embodiment, referring to Figure 2 , Figure 2 is Figure 1 a detailed process schematic diagram of step S10 in Figure 2 As shown, step S10 includes:

[0065] Step S101, detecting whether the interval duration of the vehicle switching the driving mode is less than the preset interval duration;

[0066] Step S102, if so, detecting whether the number of times of switching the driving mode within the preset monitoring duration is greater than the preset number of switching times;

[0067] Step S103, if so, determining that the detection result is that the vehicle frequently switches the driving mode.

[0068] In this embodiment, first, it is detected whether the interval duration of the vehicle switching the driving mode is less than the preset interval duration. The preset interval duration is, for example, 5 seconds. When the interval duration of the vehicle switching the driving mode is less than 5 seconds, it is further detected whether the number of times of switching the driving mode within the preset monitoring duration is greater than the preset number of switching times. For example, if the number of times of switching the driving mode within the preset monitoring duration of 20 seconds is greater than the preset number of switching times of 5 times, it is determined that the detection result is that the vehicle frequently switches the driving mode.

[0069] Further, in one embodiment, referring to Figure 3, Figure 3 is Figure 1 a detailed process schematic diagram of step S20 in, as Figure 3 shown, step S20 includes:

[0070] Step S201, detect whether the preset conditions are met, and the preset conditions include:

[0071] The switched driving mode is to lift the vehicle;

[0072] The distribution valve of the air storage tank and the valve of the air spring are both in the open state;

[0073] The air pump is in the closed state;

[0074] Step S202, if the above preset conditions are met simultaneously, determine that the detection result is to inflate the air spring only using the air storage tank.

[0075] In this embodiment, when it is detected in step S10 that the vehicle frequently switches the driving mode, it is determined whether to inflate the air spring only using the air storage tank by detecting whether the above preset conditions are met simultaneously.

[0076] Further, in one embodiment, referring to Figure 4 , Figure 4 is a schematic diagram of the air spring inflation and exit process of an embodiment of the air spring control method of the present invention. As Figure 4 shown, after step S50, it includes:

[0077] Step S60, stop inflating the air spring using the air storage tank and use the air pump to inflate the air storage tank;

[0078] Step S70, when it is detected that the current pressure value of the air storage tank is greater than the preset pressure value, exit the underpressure mode of the air storage tank.

[0079] In this embodiment, when it is recognized in step S40 that the underpressure mode of the air storage tank is entered, it means that the pressure in the air storage tank is relatively low and cannot normally inflate the air spring. Therefore, stop inflating the air spring using the air storage tank and use the air pump to inflate the air storage tank with external gas to restore the pressure of the air storage tank to normal. When it is detected that the current pressure value of the air storage tank is greater than the preset pressure value, the underpressure mode of the air storage tank can be exited.

[0080] Further, in one embodiment, the exiting of the underpressure mode of the air storage tank includes:

[0081] Turn off the air pump and give a reminder to exit the underpressure mode of the air storage tank;

[0082] The air spring responds to the last driving mode request before entering the underpressure mode of the air storage tank.

[0083] In this embodiment, when it is detected that the current pressure value of the air storage tank is greater than the preset pressure value, the underpressure mode of the air storage tank is exited. At this time, the pressure of the air storage tank is normal, and the gas in the air storage tank is relatively sufficient, and the air spring can be normally inflated. Therefore, the underpressure mode of the air storage tank can be exited, the inflation of the air spring by the air pump is turned off, and at the same time, reminders for exiting the underpressure mode of the air storage tank are given through means such as lights, voices, and meters. For example, reminders such as "The underpressure mode of the air storage tank is exited, and the air spring resumes normal use" are given. The air spring can respond to the last driving mode request before entering the underpressure mode of the air storage tank.

[0084] Further, in one embodiment, the preset monitoring duration and the preset switching times are determined according to the working pressure, the working volume of the air storage tank, and the weight of the vehicle.

[0085] In this embodiment, for different air storage tanks with different working pressures, working volumes, and vehicle weights, during the preset monitoring duration, the preset number of driving mode switches has different impacts on the pressure reduction of the air storage tank. Therefore, the preset monitoring duration and the preset switching times can be calibrated according to the working pressure, the working volume of the air storage tank, and the weight of the vehicle. Then, during implementation, the preset monitoring duration and the preset switching times are determined according to the working pressure, the working volume of the air storage tank, and the weight of the vehicle. The preset monitoring duration is, for example, 20 seconds, and the preset switching times are, for example, 5 times.

[0086] In a second aspect, an embodiment of the present invention further provides an air spring control device.

[0087] Referring to Figure 5 , Figure 5 is a schematic diagram of the functional modules of an embodiment of the air spring control device of the present invention.

[0102] The air pump is in a closed state;

[0103] If the above preset conditions are simultaneously satisfied, determine that the detection result is that only the air storage tank is used to inflate the air spring.
