[0002] With the continuous development of technology, vehicles have become an indispensable means of transportation in people's daily lives, and comfort is one of the important indicators for measuring vehicle performance. As a key component affecting vehicle comfort and handling, the air suspension system plays an important role in mitigating road bumps and improving the riding experience.

[0003] In related technologies, air suspension systems cannot adjust the compressor speed according to their current state, resulting in a poor user experience. Summary of the Invention

[0020] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0021] The following describes in detail, with reference to the accompanying drawings, an adjustment method and apparatus for an air suspension system according to an embodiment of this application.

[0022] Figure 1 This application provides an embodiment of an air suspension system adjustment method, such as... Figure 1 As shown, the method includes:

[0023] S101. Obtain the air spring pressure value of each air spring in the air suspension system, and determine the gas capacity of each air spring based on the air spring pressure value of each air spring.

[0024] S102. Determine the target speed of the compressor in the air suspension system based on the gas capacity of each air spring.

[0025] S103, In response to a height adjustment command for the air suspension system, control the compressor to adjust the height of the air suspension system according to the target speed.

[0026] It is understood that the air suspension system adjustment method provided in this example is applicable to vehicles equipped with air suspension systems. These vehicles include vehicles with autonomous or intelligent driving capabilities (including passenger vehicles (e.g., cars, buses, coaches, minibuses, etc.), cargo vehicles (e.g., ordinary trucks, box trucks, trailer trucks, enclosed trucks, tank trucks, flatbed trucks, container trucks, dump trucks, special structure trucks), special vehicles (e.g., logistics delivery vehicles, automated guided vehicles (AGVs), patrol vehicles, cranes, excavators, bulldozers, loaders, road rollers, off-road engineering vehicles, armored engineering vehicles, sewage treatment vehicles, sanitation vehicles, vacuum trucks, floor scrubbers, water sprinkler trucks, sweeping robots, food delivery robots, shopping guide robots, lawnmowers, golf carts, etc.), recreational vehicles (e.g., amusement vehicles, amusement park autonomous driving devices, balance bikes, etc.), and rescue vehicles (e.g., fire trucks, ambulances, power repair vehicles, engineering emergency rescue vehicles, etc.)).

[0027] Understandably, an air suspension system includes a control unit, air tank, air springs, and compressor. When the vehicle height needs to be increased, the control unit determines, based on sensor signals, that air needs to be added to the air springs. The compressor starts, drawing in outside air and compressing it to produce high-pressure gas. The control system opens the air supply solenoid valve connecting the compressor and the air springs, allowing the high-pressure gas to enter. As the high-pressure gas enters, the air springs expand and rise, gradually increasing the vehicle height. When the vehicle height reaches the target value, the control system closes the air supply solenoid valve and stops the compressor. In some examples, the compressor also stores excess gas in the air tank, which can be used to replenish the air springs later. When the vehicle height needs to be decreased, the control unit determines, based on sensor signals, that the air springs need to be deflated. The control unit controls the compressor to run in reverse, absorbing gas from the air springs and releasing it into the air tank. The air springs decrease in size, and the vehicle height gradually decreases.

[0028] It is understood that an air suspension system is equipped with at least two air springs; for example, when an air suspension system is equipped with two air springs, the two air springs are located on the front axle of the vehicle (that is, each air spring corresponds to one wheel on the front axle), and when an air suspension system is equipped with four air springs, two air springs are located on the front axle of the vehicle and two air springs are located on the rear axle of the vehicle (that is, each air spring corresponds to one wheel on the rear axle).

[0029] It is understandable that the rising and falling rates of the air springs in an air suspension system are affected by the total gas volume of the air suspension system. Specifically, when the total gas volume in the air suspension system is large, the increase in gas pressure will be relatively small for the same compression stroke. Conversely, when the total gas volume in the air suspension system is small, the increase in gas pressure will be relatively large for the same compression stroke. Based on the above reasons, with other parameters (such as temperature and compressor speed) remaining constant, the higher the total gas volume in the air suspension system, the longer it takes for the air springs to rise or fall to the set height; and the lower the total gas volume in the air suspension system, the shorter it takes for the air springs to rise or fall to the set height.

[0030] Based on the above principle, this application determines the gas capacity of each air spring and, based on the gas capacity of the air spring, determines the target speed of the compressor in the air suspension system, so that the determined target speed can match the gas capacity of the air spring in the air suspension system.

[0031] Understandably, to avoid the need for additional sensors or inaccurate measurements due to directly measuring the gas capacity of each air spring in the air suspension system, this application obtains the air spring pressure value of each air spring in the air suspension system. The air spring pressure value reflects the gas capacity of the air spring. Therefore, this example can determine the gas capacity of each air spring based on the air spring pressure value of each air spring. The air spring pressure value can be detected by a pressure sensor, which will not be elaborated here.

[0032] It is understood that in some examples of this application, the gas volume of the air spring can also be directly collected by setting a gas volume sensor, which will not be elaborated here.

[0033] It is understandable that, in order to avoid the vehicle's vibration affecting the air springs during vehicle movement and causing inaccurate air spring pressure values ​​for each air spring, this application will acquire the vehicle status. Only when the vehicle status meets the preset pressure acquisition status will the air spring pressure value for each air spring in the air suspension system be acquired. The aforementioned pressure acquisition status includes, but is not limited to, at least one of the following: (1) the state where the up request response completion flag Flg_UpOver is 1; (2) the state where the down request response completion flag Flg_DownOver is 1; (3) the state where the all door closed flag Flg_AllDorClose is 1; (4) the state where the gear is shifted into or out of P gear; (5) the state where the vehicle has just been powered on.

[0034] In some examples, after determining the target speed, this application will respond to a height adjustment command for the air suspension system and control the compressor to adjust the height of the air suspension system according to the target speed; for example, if the target speed is determined to be 3000 rad / s, this application will control the compressor to adjust the height of the air suspension system according to 3000 rad / s.

[0035] According to the technical solution provided in this application, the air spring pressure value of each air spring in the air suspension system is obtained, and the gas capacity of each air spring is determined based on the air spring pressure value. The target speed of the compressor in the air suspension system is determined based on the gas capacity of each air spring. In response to a height adjustment command for the air suspension system, the compressor is controlled to adjust the height of the air suspension system according to the target speed. This application achieves accurate acquisition of the air spring gas capacity by obtaining the air spring pressure value, and then determines the target speed of the compressor based on the air spring gas capacity, so that the target speed of the compressor matches the gas capacity of the air spring. Subsequently, the compressor is controlled to adjust the height of the air suspension system based on the target speed, realizing real-time and dynamic matching of the compressor speed and the gas capacity of the air spring. This makes the compressor output more efficient and precise, avoiding the problem that the air suspension system cannot adjust the compressor speed according to its current state due to a fixed compressor speed, resulting in a poor user experience.

[0036] In some embodiments, such as Figure 2 As shown, the gas capacity of each air spring is determined based on the air bladder pressure value of each air spring, including:

[0037] S201. Obtain the mapping relationship between pressure value and gas volume;

[0038] S202. Match the air pressure value of each air spring with the mapping relationship between the pressure value and the gas capacity to obtain the gas capacity of each air spring.

[0039] It is understandable that, assuming other parameters of the air spring (such as temperature and height) are the same, the air spring's air pressure value is directly proportional to the air spring's gas capacity. That is, the higher the air spring's air pressure value, the higher the air spring's gas capacity, and the lower the air spring's air pressure value, the lower the air spring's gas capacity.

[0040] The mapping relationship between the pressure value and gas volume of the air spring in the air suspension system can be obtained by relevant personnel through testing of the air spring, while the mapping relationship between the pressure value and gas volume of the air spring in the air suspension system can be determined by a big data model based on various parameters of the air suspension system (such as the air spring material).

[0041] It is understood that this application does not limit the format of the mapping relationship between pressure value and gas capacity. The mapping relationship between pressure value and gas capacity can be any format of key-value pair, hash, table, or database.

[0042] It is understandable that each air spring in an air suspension system corresponds to a pressure value and a gas volume mapping relationship. For example, if an air suspension system includes a left front air spring, a right front air spring, a left rear air spring, and a right rear air spring, then the left front air spring corresponds to a pressure value and a gas volume mapping relationship, the right front air spring corresponds to a pressure value and a gas volume mapping relationship, the left rear air spring corresponds to a pressure value and a gas volume mapping relationship, and the right rear air spring corresponds to a pressure value and a gas volume mapping relationship.

[0043] In some examples, at least two air springs in the air suspension system correspond to a pressure value and a gas volume mapping relationship; for example, if the air suspension system includes a left front air spring, a right front air spring, a left rear air spring, and a right rear air spring, then the left front air spring and the right front air spring correspond to a pressure value and a gas volume mapping relationship, and the left rear air spring and the right rear air spring correspond to a pressure value and a gas volume mapping relationship.

[0044] This application matches the air spring pressure value with the mapping relationship between pressure value and gas volume to obtain the gas volume of each air spring. For example, this application uses a table format for the mapping relationship between pressure value and gas volume, as shown in Table 1 below:

[0045] Table 1: Mapping Relationship between Pressure Value and Gas Volume

[0046] Pressure value P (bar) 3 3.5 4 4.5 5 5.5 6 6.5 7 7.5 8 … Gas volume (g) 0.15 0.16 0.17 0.18 0.19 0.2 0.21 0.22 0.23 0.24 0.25 …

[0047] As shown in Table 1 above, when the air spring is at a preset height and the air spring temperature is a predetermined temperature, if the air spring pressure is 3 bar, the air spring capacity is determined to be 0.15 g; if the air spring pressure is 3.5 bar, the air spring capacity is determined to be 0.16 g; and if the air spring pressure is 8 bar, the air spring capacity is determined to be 0.25 g.

[0048] It's understandable that the relationship between gas volume and temperature is clearly reflected in the gas law, especially in the ideal gas law. The ideal gas law is stated as PV = nRT, where P represents the gas pressure, V represents the gas volume, n represents the amount of substance (i.e., the number of moles), R is the ideal gas constant, and T represents the absolute temperature of the gas (usually in Kelvin). Keeping other variables (such as pressure and amount of substance) constant, the gas volume V is directly proportional to the absolute temperature T. This means that when the gas temperature increases, if the pressure remains constant, the gas volume will increase; conversely, when the gas temperature decreases, if the pressure remains constant, the gas volume will decrease.

[0049] Based on the above reasons, it is known that the gas capacity of an air spring is also affected by temperature. Therefore, in constructing the mapping relationship between pressure value and gas capacity, this example can also consider the influence of temperature on the gas capacity of the air spring. Subsequently, the temperature of the air spring (or the ambient temperature) is obtained, and then the obtained temperature and the air spring's air bladder pressure value are matched with the mapping relationship between pressure value and gas capacity to obtain the gas capacity of each air spring, making the gas capacity of each air spring more accurate.

[0050] For example, taking into account the mapping relationship between pressure value and gas volume in temperature as a tabular form, as shown in Table 2 below:

[0051] Table 2: Mapping relationship between pressure value and gas volume considering temperature.

[0052]

[0053] As shown in Table 1 above, when the air spring is at a preset height and the air spring temperature is 25°C, if the air spring pressure is 3 bar, the air spring capacity is determined to be 0.16 g; if the air spring pressure is 3.5 bar, the air spring capacity is determined to be 0.25 g… if the air spring pressure is 8 bar, the air spring capacity is determined to be 0.25 g, and so on. Similarly, when the air spring temperature is 35°C, if the air spring pressure is 3 bar, the air spring capacity is determined to be 0.13 g; if the air spring pressure is 3.5 bar, the air spring capacity is determined to be 0.14 g… if the air spring pressure is 8 bar, the air spring capacity is determined to be 0.23 g.

[0054] In some examples, this application may also consider the influence of weather temperature and altitude on gas capacity to correct the determined gas capacity and obtain a more accurate gas capacity. Specifically, a first correction value is determined based on the current altitude and air pressure of the vehicle, and a second correction value is determined based on the weather temperature. The determined gas capacity is then processed according to the first and second correction values ​​to obtain the adjusted gas capacity. Processing the determined gas capacity according to the first and second correction values ​​to obtain the adjusted gas capacity includes: weighting the determined gas capacity according to the first and second correction values ​​to obtain the adjusted gas capacity; that is, the adjusted gas capacity M2 = M1 * f n *f t Where M2 is the adjusted gas capacity, M1 is the gas capacity determined based on the airbag pressure value of each air spring, and f n f is the first correction value. t This is the second correction value.

[0055] The process of determining the first correction value based on the vehicle's current altitude and atmospheric pressure includes: matching the vehicle's current altitude and atmospheric pressure with a pre-set correspondence between altitude, atmospheric pressure, and correction values ​​to obtain the first correction value corresponding to the vehicle's current altitude and atmospheric pressure. The process of determining the second correction value based on weather temperature includes: matching the weather temperature with a pre-set correspondence between temperature and correction values ​​to obtain the second correction value corresponding to the weather temperature.

[0056] According to the technical solution provided in the embodiments of this application, the mapping relationship between pressure value and gas capacity is obtained; the airbag pressure value of each air spring is matched with the mapping relationship between pressure value and gas capacity to obtain the gas capacity of each air spring. The above steps take into account the relationship between pressure value and gas capacity. Subsequently, the gas capacity of the air spring is accurately obtained by obtaining the airbag pressure value of the air spring, thereby achieving accurate acquisition of gas capacity.

[0057] In some embodiments, such as Figure 3 As shown, the target speed of the compressor in the air suspension system is determined based on the gas capacity of each air spring, including:

[0058] S301. Determine the total gas volume of the air suspension system based on the gas capacity of each air spring;

[0059] S302. Match the total gas volume of the air suspension system with the pre-set mapping relationship between capacity and speed to obtain the target speed.

[0060] It is understood that, in order to make the target speed take into account the total gas volume of the air suspension system, this application will determine the total gas volume of the air suspension system based on the gas capacity of each air spring, which is the current actual gas volume in the air suspension system.

[0061] Specifically, the total gas volume m of the air suspension system ALlOpre for:

[0062] m ALLOpre =m fl +m fr +m rl +m rr ;

[0063] In the formula, m ALLOpre The total amount of gas in the air suspension system is m fl The gas capacity corresponding to the left front air spring is m. fr The gas capacity corresponding to the right front air spring is m. rl The gas capacity corresponding to the left rear air spring is m. rr This represents the gas capacity corresponding to the right rear air spring.

[0064] In some examples, if the air suspension system includes an air tank, the total gas volume of the air suspension system must also take into account the gas volume in the air tank, as detailed below:

[0065] m ALLOpre =m compopre +m fl +m fr +m rl +m rr ;

[0066] In the formula, m ALLOpre The total amount of gas in the air suspension system, m comp The volume of gas in the storage tank, m fl The gas capacity corresponding to the left front air spring is m. fr The gas capacity corresponding to the right front air spring is m. rl The gas capacity corresponding to the left rear air spring is m. rr This represents the gas capacity corresponding to the right rear air spring.

[0067] It is understandable that the gas volume in the gas storage tank can also be determined based on the pressure value of the gas storage tank. Specifically, after obtaining the pressure value of the gas storage tank, this application matches the pressure value of the gas storage tank with the mapping relationship between the corresponding pressure value and the gas volume to obtain the gas volume of the gas storage tank.

[0068] It is understandable that the mapping relationship between the pressure value and the gas volume of the gas storage tank can be any form, such as hash, key-value pair, or table. Taking the mapping relationship between the pressure value and the gas volume of the gas storage tank as a table as an example, the mapping relationship between the pressure value and the gas volume of the gas storage tank is shown in Table 3 below:

[0069] Table 3: Mapping Relationship between Pressure Value and Gas Quantity for Gas Storage Tanks

[0070]

[0071]

[0072] Specifically, when the temperature (or ambient temperature) of the gas tank is 25°C, if the pressure of the gas tank is 3 bar, the gas volume in the gas tank is 0.2; if the pressure of the gas tank is 3.5 bar, the gas volume in the gas tank is 0.21; if the pressure of the gas tank is 4 bar, the gas volume in the gas tank is 0.22… if the pressure of the gas tank is 8 bar, the gas volume in the gas tank is 0.3, and so on.

[0073] In some examples, after obtaining the total gas volume of the air suspension system, this application will also match the total gas volume of the air suspension system with a pre-set mapping relationship between capacity and speed to obtain the target speed. The pre-set mapping relationship between capacity and speed can be any of the following forms: key-value pairs, hash, or table. For example, taking the pre-set mapping relationship between capacity and speed in tabular form, as shown in Table 4 below:

[0074] Table 4: Mapping Relationship between Capacity and Rotation Speed

[0075]

[0076] As shown in Table 4 above, when the total gas volume of the air suspension system is 1.1g, the compressor speed is determined to be 5500 rad / s; when the total gas volume of the air suspension system is 1.15g, the compressor speed is determined to be 5300 rad / s; and when the total gas volume of the air suspension system is 1.55g, the compressor speed is determined to be 4200 rad / s.

[0077] According to the technical solution provided in the embodiments of this application, the total gas volume of the air suspension system is determined based on the gas capacity of each air spring, thereby accurately obtaining the total gas volume of the air suspension system. The total gas volume of the air suspension system is matched with a pre-set mapping relationship between capacity and speed to obtain the target speed, so that the target speed takes into account the total gas volume of the air suspension system, thus improving the adaptability of the target speed to the air suspension system.

[0078] In some embodiments, such as Figure 4 As shown, the air spring pressure value of each air spring in the air suspension system is obtained, including:

[0079] S401. Obtain the initial air spring pressure value multiple times within a preset target time period;

[0080] S402. Determine the average airbag pressure value based on the initial airbag pressure values ​​obtained multiple times, and use the average airbag pressure value as the airbag pressure value of the air spring.

[0081] In some examples, in order to accurately obtain the air spring airbag pressure value, this application will obtain the initial air spring airbag pressure value multiple times within a preset target time period, and then determine the average airbag pressure value based on the multiple obtained initial airbag pressure values, and use the average airbag pressure value as the air spring airbag pressure value.

[0082] It is understandable that during the detection of the air spring's airbag pressure value, the air valve is opened to connect the pressure sensor and the air valve. This process causes fluctuations in the air spring's airbag pressure value, leading to errors in the measured airbag pressure value. For the above reasons, this application will acquire the initial airbag pressure value of the air spring multiple times within a pre-set target duration. For example, taking a target duration of 1 second as an example, this application will open the air valve for 1 second, and take an initial airbag pressure value every 10ms (10ms is a value set by relevant personnel according to actual needs) during the valve opening time. The average value of all the initial airbag pressure values ​​acquired during the valve opening time will be used to obtain the average airbag pressure value, and the average airbag pressure value will be used as the air spring's airbag pressure value.

[0083] In some examples, this application may also set a correction value based on the actual vehicle conditions, correct the initial airbag pressure value using the correction value, and then obtain the average value of all corrected initial airbag pressure values ​​to obtain the average airbag pressure value.

[0084] It is understandable that when there are multiple air springs in an air suspension system, multiple air springs can correspond to one correction value, or each air spring can correspond to one correction value, which will not be elaborated here.

[0085] It is understandable that the pressure value of the gas tank can also be obtained through a pressure sensor, and the gas tank can also correspond to a correction value.

[0086] This example does not restrict the testing order for pressure testing of the air tank and air springs. Relevant personnel can flexibly set it according to actual needs. Example 1 first tests the air tank, and then tests the pressure of the left front air spring, right front air spring, left rear air spring and right rear air spring. First, open the air valve between the pressure sensor and the air tank and keep it open for 700ms (that is, close the air valve between the air tank and the pressure sensor after 700ms. This 700ms is a value flexibly set by relevant personnel according to actual needs). Read the pressure value of the pressure sensor just before the valve is closed, and then subtract the corresponding correction value of the air tank to obtain the pressure value of the air tank.

[0087] After the air tank pressure is read, open the air valve between the left front air spring and the pressure sensor and keep it open for 700ms. Read the pressure value of the pressure sensor just before the valve is closed, and then subtract the correction value corresponding to the left front air spring to obtain the airbag pressure value corresponding to the left front air spring.

[0088] After the airbag pressure value of the left front air spring is detected, the air valve between the right front air spring and the pressure sensor is opened and kept open for 700ms (that is, the air valve between the right front air spring and the pressure sensor is closed after 700ms). The pressure value of the pressure sensor is read just before the valve is closed, and then the correction value corresponding to the right front air spring is subtracted to obtain the airbag pressure value corresponding to the right front air spring.

[0089] After the airbag pressure value of the right front air spring is detected, the air valve between the left rear air spring and the pressure sensor is opened and kept open for 700ms (that is, the air valve between the left rear air spring and the pressure sensor is closed after 700ms). The pressure value of the pressure sensor is read just before the valve is closed, and then the correction value corresponding to the left rear air spring is subtracted to obtain the airbag pressure value corresponding to the left rear air spring.

[0090] After the airbag pressure value of the left rear air spring is detected, the air valve between the right rear air spring and the pressure sensor is opened and kept open for 700ms (that is, the air valve between the right rear air spring and the pressure sensor is closed after 700ms). The pressure value of the pressure sensor is read just before the valve is closed, and then the correction value corresponding to the right rear air spring is subtracted to obtain the airbag pressure value corresponding to the right rear air spring.

[0091] According to the technical solution provided in the embodiments of this application, the initial airbag pressure value of the air spring is obtained multiple times within a preset target time period; the average airbag pressure value is determined based on the multiple obtained initial airbag pressure values, and the average airbag pressure value is used as the airbag pressure value of the air spring. The above solution reduces the influence of error on the actual airbag pressure value of the air spring by obtaining the average airbag pressure value as the actual airbag pressure value of the air spring.

[0092] In some embodiments, such as Figure 5 As shown, the method also includes:

[0093] S501. When the current state of the vehicle meets the preset target state, determine the optimal gas quantity corresponding to the air suspension system.

[0094] S502: Control the compressor to inflate the air suspension system so that the total gas volume of the air suspension system reaches the optimal gas volume.

[0095] To avoid affecting vehicle stability by adjusting the total gas volume of the air suspension system during vehicle use, this application will obtain the current state of the vehicle and determine the optimal gas volume for the air suspension system only when the current state of the vehicle meets the preset target state.

[0096] It is understood that the aforementioned target state refers to the vehicle being in grid wake-up mode, in park (P) gear, and the user not being in the vehicle. The air suspension system periodically wakes up to the network (e.g., at 4H, 8H, 12H). The optimal air quantity for the air suspension system is determined only if the vehicle's current state matches the aforementioned target state when the air suspension system performs a grid wake-up. It is understood that the aforementioned target state can be flexibly set by relevant personnel according to actual needs, and this application does not impose any limitations on it.

[0097] It is understandable that the rising and falling rates of the air springs in an air suspension system are affected by the total gas volume in the air suspension system. Specifically, both a large (or small) total gas volume in the air suspension system will affect the rising or falling rate.

[0098] Based on the above reasons, in order to ensure the adjustment efficiency (ascent rate, descent rate) of the air spring, this application needs to adjust the total gas volume of the air suspension system so that the total gas volume of the air suspension system is in the optimal state (that is, to make the total gas volume of the air suspension system the optimal gas volume).

[0099] In some examples, the optimal gas quantity is obtained through testing based on the actual conditions of the vehicle. Therefore, determining the optimal gas quantity for the air suspension system includes: querying a pre-set optimal gas quantity table to obtain the optimal gas quantity. For example, under the condition of a pre-set ascent / descent distance, the adjustment time corresponding to different gas quantities is shown in Table 5 below:

[0100] Table 5: Mapping Relationship between Gas Quantity and Adjustment Time in Air Suspension Systems

[0101] Gas quantity (g) in the air suspension system 1.2g 1.25g 1.3g 1.35g 1.40g 1.45g 1.50g 1.55g … Adjust time (seconds) 35 32 30 28 23 22 25 30 …

[0102] As shown in Table 5 above, with the ascending / descending distance preset, the adjustment time is 35s when the air supply volume of the air suspension system is 1.2g, 32s when the air supply volume is 1.25g, and 30s when the air supply volume is 1.55g. In the example above, the optimal air supply volume is determined to be 1.45g.

[0103] According to the technical solution provided in the embodiments of this application, when the current state of the vehicle meets the preset target state, the optimal gas quantity corresponding to the air suspension system is determined; the compressor is controlled to inflate the air suspension system so that the total gas quantity of the air suspension system reaches the optimal gas quantity, thereby improving the height adjustment efficiency of the air suspension system.

[0104] In some embodiments, such as Figure 6 As shown, determining the optimal gas quantity for the air suspension system includes:

[0105] S601. Obtain the initial gas quantity corresponding to the air suspension system;

[0106] S602. Determine the first influencing factor based on the time required for the air suspension system to adjust to the predetermined height under the initial gas volume and the time required for the air suspension system to adjust to the predetermined height under the current gas volume.

[0107] S603. The initial gas quantity is weighted according to the first influencing factor to determine the optimal gas quantity.

[0108] The initial gas quantity is a pre-set value, which can be flexibly adjusted by relevant personnel according to the actual situation of the air suspension system.

[0109] In some examples, the first influencing factor is determined based on the time required for the air suspension system to adjust to a predetermined height with an initial gas volume and the time required for the vehicle's air suspension system to adjust to a predetermined height with the current gas volume; specifically, the ratio of the time required for the air suspension system to adjust to a predetermined height with an initial gas volume to the time required for the vehicle's air suspension system to adjust to a predetermined height with the current gas volume is used as the first influencing factor.

[0110] In some examples, the initial gas quantity is weighted according to a first influencing factor to determine the optimal gas quantity. Specifically, let the initial gas quantity be M. com The first impact factor is f tep Then the optimal gas quantity M req =M com *f tep .

[0111] According to the technical solution provided in the embodiments of this application, the initial gas quantity corresponding to the air suspension system is obtained; a first influencing factor is determined based on the time required for the air suspension system to adjust to a predetermined height under the initial gas quantity and the time required for the air suspension system to adjust to a predetermined height under the current gas quantity; the initial gas quantity is weighted according to the first influencing factor to determine the optimal gas quantity. This method takes into account the change in the air suspension system's current gas quantity compared to the initial gas quantity, determines the first influencing factor based on this change, and processes the initial gas quantity according to the first influencing factor to obtain the optimal gas quantity, thereby ensuring the adjustment efficiency of the air suspension system.

[0112] In some embodiments, such as Figure 7 As shown, the initial gas quantity is determined based on the first influencing factor to determine the optimal gas quantity, including:

[0113] S701. Determine the second influencing factor based on the vehicle's current driving mode, and determine the third influencing factor based on the temperature corresponding to the air suspension system.

[0114] S702. The initial gas quantity is weighted according to the first influence factor, the second influence factor, and the third influence factor to obtain the optimal gas quantity.

[0115] The second influencing factor is a value determined based on the vehicle's driving mode. The initial air volume differs depending on the driving mode. For example, in Comfort mode, to provide a smooth and comfortable experience, the suspension needs to increase the air volume within the air suspension system, raising the vehicle body, softening the shock absorbers, and absorbing more road surface debris. In Sport mode, no change in the air volume is required. In Off-Road mode, the air volume is significantly increased, improving the suspension's ride height and ground clearance. Therefore, this application pre-sets a correspondence between driving modes and parameter values. By matching the vehicle's current driving mode with this pre-set correspondence, the second influencing factor can be obtained.

[0116] For example, as shown in Table 6 below:

[0117] Table 6: Correspondence between Driving Mode and Parameter Value

[0118] Driving Mode Comfort mode Sports Mode Off-road mode Parameter value 0.95 1 1.05

[0119] As shown in Table 6 above, when the vehicle's current driving mode is Comfort mode, the second influence factor is determined to be 0.95; when the vehicle's current driving mode is Sport mode, the second influence factor is determined to be 1; and when the vehicle's current driving mode is Off-road mode, the second influence factor is determined to be 1.05.

[0120] The third influencing factor is a value determined based on the temperature inside the vehicle's air suspension system. It is understandable that the lifting and lowering efficiency of the air suspension system varies at different temperatures. To ensure the stability of the lifting and lowering efficiency of the air suspension system, this application also needs to consider the influence of temperature on the lifting and lowering efficiency.

[0121] Specifically, this application pre-sets a correspondence between temperature and the third influencing factor. By obtaining the current temperature in the air suspension system and then matching the current temperature with the correspondence between temperature and the third influencing factor, the corresponding third influencing factor can be obtained.

[0122] For example, the correspondence between temperature and the third influencing factor is shown in Table 7 below:

[0123] Table 7: Correspondence between air temperature and the third influencing factor

[0124] Temperature (°C) -20～-10 -10～0 0～10 10～20 20～30 30～40 40～50 … Third Impact Factor 0.91 0.93 0.95 0.98 1 0.98 0.95 …

[0125] Taking the current temperature within the air suspension system as an example, which is between -20℃ and -10℃, the corresponding third influencing factor is determined to be 0.91.

[0126] In some examples, the initial gas quantity is weighted according to the first, second, and third influence factors to obtain the optimal gas quantity. That is, let the first influence factor be f. tep The second impact factor is f p The third impact factor is f m The initial gas quantity is M com Then the optimal gas quantity M req =M com *f tep *f p *f m .

[0127] According to the technical solution provided in the embodiments of this application, a second influencing factor is determined based on the current driving mode of the vehicle, and a third influencing factor is determined based on the temperature corresponding to the air suspension system. The initial gas quantity is weighted based on the first, second, and third influencing factors to obtain the optimal gas quantity. In this application, the changes in the current gas capacity of the air suspension system compared to the initial gas quantity, the influence of the driving mode on the optimal gas quantity, and the influence of temperature on the optimal gas quantity are taken into account, so as to more accurately determine the optimal gas quantity and thus ensure the adjustment efficiency of the air suspension system.

[0128] To better understand this application, this embodiment provides a more specific example for illustration. For example, suppose the initial gas volume of the air suspension system is 1.45g, the time required for the air suspension system to adjust to a predetermined height under the initial gas volume is 22 seconds, the current gas volume of the air suspension system is 1.2g, and the time required to adjust to a predetermined height is 35 seconds, then the first influence factor is 22 / 35 = 0.63.

[0129] For example, taking an optimal gas quantity of 1.45g as an example, when the gas quantity of the air suspension system is 1.45g, the suspension's ascent (descent) rate reaches its optimal level. However, in a closed system, gas leakage can occur. When the gas quantity is less than or greater than 1.45g, the ascent (descent) rate will decrease. Therefore, when the gas quantity of the air suspension system is not equal to 1.45g, the gas quantity of the air suspension system is either deflated or inflated. However, deflation and inflation would affect the user experience when the vehicle is in use, so they are not performed in this case, and 1.45g is taken as the optimal gas quantity. When the vehicle is locked, the air suspension system is woken up from the network at regular intervals of 4H, 8H, 12H… When the current state of the vehicle meets the target state, the gas quantity of the air suspension system is adjusted to determine the total gas quantity of the air suspension system as the optimal gas quantity.

[0130] In some examples, the optimal gas quantity range is ±0.01g. Taking an optimal gas quantity of 1.45g as an example, when the total gas quantity of the air suspension system is <1.44g, the air suspension system is inflated; when the total gas quantity of the air suspension system is >1.46g, the air suspension system is deflated. Maintaining the total gas quantity of the air suspension system between 1.44g and 1.46g ensures the rising and falling efficiency of the air springs in the air suspension system. Furthermore, ensuring the gas quantity of the air suspension system is within a suitable range also helps protect components and increases the service life of the air suspension system.

[0131] In some examples, when the total gas volume of the air suspension system is less than the optimal gas volume and the air suspension system needs to be inflated, this application determines the inflation time based on the total gas volume and the preset optimal gas volume. Specifically, this application obtains the gas volume difference between the total gas volume and the optimal gas volume, matches the gas volume difference with the preset mapping relationship between the gas volume difference and the inflation time, and then obtains the corresponding inflation time. Then, the compressor is controlled to inflate the air suspension system according to the inflation time so that the total gas volume of the air suspension system reaches the optimal gas volume.

[0132] In some examples, when the total gas volume of the air suspension system is greater than the optimal gas volume and the air suspension system needs to be deflated, this application determines the deflation time based on the total gas volume and the preset optimal gas volume. Specifically, this application obtains the gas volume difference between the total gas volume and the optimal gas volume, matches the gas volume difference with the preset mapping relationship between the gas volume difference and the inflation time, and then obtains the corresponding deflation time. Then, the compressor is controlled to deflate the air suspension system according to the deflation time, so that the total gas volume of the air suspension system reaches the optimal gas volume.

[0133] It is understood that the aforementioned pre-set mapping relationship between gas quantity difference and inflation time can be obtained by relevant personnel through testing of the vehicle's air suspension system. The aforementioned pre-set mapping relationship between gas quantity difference and inflation time can also be determined by a deep learning model based on various parameters of the vehicle. Furthermore, the aforementioned pre-set mapping relationship between gas quantity difference and inflation time can be any form of hash, key-value pair, or table, and this application does not limit it in this way.

[0134] In some examples, to avoid the problem of vehicle height changes and driver slack caused by inflating / deflating the air springs in the air suspension system, only the air tank of the air suspension system may be charged or deflated; in other examples, to accurately adjust the total gas volume of the air suspension system, both the air springs and the air tank in the air suspension system may be inflated or deflated.

[0135] In some examples, controlling the compressor to inflate the air suspension system according to the optimal gas quantity, so that the total gas quantity of the air suspension system reaches the optimal gas quantity, includes: obtaining the current load of the vehicle, determining the compressor's inflation speed based on the current load, and controlling the compressor to inflate the air suspension system according to the inflation speed, so that the total gas quantity of the air suspension system reaches the optimal gas quantity.

[0136] It is understandable that when the vehicle load changes (such as an increase or decrease in load), the inflation and deflation efficiency of the air springs in the air suspension system will be affected. For example, when the vehicle load increases, if the compressor continues to operate at the original speed, the inflation efficiency of the air suspension system will decrease, resulting in a slower response speed and affecting the user experience. Based on the above reasons, in order to adjust the total gas volume of the air suspension system to the optimal gas volume within the inflation time, this application further obtains the vehicle's current load and matches the current load with the mapping relationship between load and speed to obtain the compressor's inflation speed, which is the speed at which the compressor inflates the air suspension within the inflation time.

[0137] It is understood that the above-mentioned load and speed mapping relationship can be obtained by relevant personnel through multiple tests on the vehicle's air suspension system. The above-mentioned load and speed mapping relationship can also be obtained by a deep learning model based on the parameters of the vehicle's air suspension system. Furthermore, this application does not limit the form of the above-mentioned load and speed mapping relationship. The load and speed mapping relationship can be any form of key-value pairs, hash, or table.

[0138] After obtaining the inflation speed, the compressor is controlled to inflate the air suspension system according to the inflation speed, so that the total gas volume of the air suspension system reaches the optimal gas volume.

[0139] According to the technical solution provided in the embodiments of this application, the current load of the vehicle is obtained, and the inflation speed of the compressor is determined based on the current load. The compressor is controlled to inflate the air suspension system according to the inflation speed, so that the total gas volume of the air suspension system reaches the optimal gas volume, thereby enabling the compressor to adjust the total gas volume of the air suspension system to the optimal gas volume within the inflation time.

[0140] In some examples, after the air suspension system is height-adjusted by controlling the compressor according to the target speed, the method further includes: acquiring the vehicle's motion posture, determining the vehicle's safety factor based on the motion posture, and adjusting the air suspension system according to a preset safety mode if the safety factor is lower than a preset safety threshold.

[0141] In some cases, adjusting the air suspension system may lead to a decrease in vehicle stability, resulting in safety hazards such as vehicle tilting and swaying. To avoid safety accidents caused by the above problems, this application will also acquire the vehicle's operating posture after adjusting the height of the air suspension system, and determine the vehicle's safety factor based on the motion posture. Different motion postures correspond to different safety factors, and the safety factor corresponding to the motion posture can be determined by relevant personnel based on the actual situation of the vehicle.

[0142] If the safety factor is lower than the preset safety threshold, it indicates that the vehicle has safety hazards such as tilting and swaying. In order to avoid safety accidents caused by the above problems, this application will adjust the air suspension system according to the preset safety mode to avoid accidents such as vehicle rollover and skidding; wherein the above safety mode is the mode of the air suspension system corresponding to improving the stability of the vehicle.

[0143] If the safety factor is not lower than the preset safety threshold, it indicates that there are no safety hazards such as tilting or swaying of the vehicle. Then, the above process is exited, and the vehicle will wait for the next height adjustment command of the air suspension system to be received before adjusting the height of the air suspension system.

[0144] According to the technical solution provided in the embodiments of this application, the motion posture of the vehicle is obtained, and the safety factor of the vehicle is determined based on the motion posture. If the safety factor is lower than the preset safety threshold, the air suspension system is adjusted according to the preset safety mode, thereby avoiding the vehicle from rolling over or skidding due to the adjustment of the air suspension system.

[0145] All of the above-mentioned optional technical solutions can be combined in any way to form the optional embodiments of this application, and will not be described in detail here.

[0148] The acquisition module 801 is used to acquire the air spring pressure value of each air spring in the air suspension system, and determine the gas capacity of each air spring based on the air spring pressure value of each air spring.

[0149] The determination module 802 is used to determine the target speed of the compressor in the air suspension system based on the gas capacity of each air spring.

[0150] The adjustment module 803 is used to control the compressor to adjust the height of the air suspension system according to the target speed in response to a height adjustment command for the air suspension system.

[0151] In some examples, the acquisition module 801 is also used to acquire the mapping relationship between pressure value and gas capacity; the air bladder pressure value of each air spring is matched with the mapping relationship between pressure value and gas capacity to obtain the gas capacity of each air spring.

[0152] In some examples, the determining module 802 is also used to determine the total gas volume of the air suspension system based on the gas capacity of each air spring; and to match the total gas volume of the air suspension system with a pre-set mapping relationship between capacity and speed to obtain the target speed.

[0153] In some examples, the acquisition module 801 is also used to acquire the initial airbag pressure value of the air spring multiple times within a preset target duration; determine the average airbag pressure value based on the multiple acquired initial airbag pressure values, and use the average airbag pressure value as the airbag pressure value of the air spring.

[0154] In some examples, the adjustment module 803 is also used to determine the optimal gas quantity corresponding to the air suspension system when the current state of the vehicle meets the preset target state; and to control the compressor to inflate the air suspension system so that the total gas quantity of the air suspension system reaches the optimal gas quantity.

[0156] In some examples, the adjustment module 803 is also used to determine a second influencing factor based on the vehicle's current driving mode, and a third influencing factor based on the temperature corresponding to the air suspension system; and to perform weighted processing on the initial gas quantity based on the first, second, and third influencing factors to obtain the optimal gas quantity.

This application achieves accurate acquisition of the gas capacity of the air spring by obtaining the air spring pressure value, and then determines the target speed of the compressor based on the gas capacity of the air spring, so that the target speed of the compressor matches the gas capacity of the air spring. Subsequently, the compressor is controlled to adjust the height of the air suspension system based on the target speed, realizing real-time and dynamic matching of the compressor speed and the gas capacity of the air spring, making the compressor output more efficient and precise, and avoiding the problem that the air suspension system cannot adjust the compressor speed according to its current state due to the fixed compressor speed, resulting in a poor user experience of the air suspension system.
