[0002] The air compressor is an important component in the vehicle, which is used to generate compressed gas, and the compressed gas is stored in the air tank after being processed by the air processing unit, and is used as the power source of the engine, the air source of the brake system, etc.

[0003] Traditionally, the air processing unit is provided with unloading valve, regeneration valve, regeneration cylinder and other components, the unloading valve controls the unloading / charging of the air compressor according to the pneumatic control signal, when the air compressor is unloaded, the regeneration cylinder blows air to the air processing unit through the regeneration valve to realize regeneration.

[0004] The traditional design has the following problems:

[0005] The unloading valve is a mechanical spring structure, which works based on the pneumatic control signal; with use, the acting pressure of the spring is continuously attenuated, which leads to slow response to the pneumatic control signal, affects the control of the air compressor, and is not conducive to energy saving of the vehicle.

[0006] The regeneration valve is also a mechanical spring structure, with use, the acting pressure of the spring is attenuated, which leads to an increase in the regeneration coefficient, and further increases the load rate of the air compressor. If a separate regeneration cylinder is provided to realize the regeneration function, it also leads to complex structure of the air processing unit and difficult arrangement; and the regeneration time is limited by the unloading time, which causes energy waste and increases the load rate of the air compressor.

[0007] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information which does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0008] The present application provides an air management system and a control method of the air management system, which can overcome the problem that the sensitivity is reduced with use in the design that the mechanical spring structure works under the action of the pneumatic control signal, leading to inaccurate and slow response; the present application can realize convenient and on-demand control of the unloading process of the air compressor and the regeneration process of the air processing unit, which is conducive to energy saving of the vehicle, avoids energy waste and increases the load rate of the air compressor; and the air management system of the present application has simple structure, low cost and convenient arrangement, and is easy to popularize and use.

[0009] According to an aspect of the present application, there is provided an air management system, comprising an electronic control unit and a pressure sensor electrically connected, and an air compressor, an air treatment unit and an air tank connected in sequence to form an air charging circuit; wherein: the air treatment unit is free of an unloading valve, a regeneration valve and a regeneration tank; the air compressor is provided with an electrically controlled clutch electrically connected to the electronic control unit; the air management system further comprises an electrically controlled valve, an air outlet of the air tank being connected to a regeneration inlet of the air treatment unit through a valve passage of the electrically controlled valve, and the electronic control unit being electrically connected to the electrically controlled valve and an exhaust valve of the air treatment unit.

[0010] In some embodiments, when the system pressure collected by the pressure sensor reaches an unloading pressure threshold, the electronic control unit controls the electrically controlled clutch to be disengaged; and when the system pressure is lower than a charging pressure threshold, the electronic control unit controls the electrically controlled clutch to be engaged.

[0011] In some embodiments, the electronic control unit stores unloading pressure thresholds and / or charging pressure thresholds corresponding to different vehicle models and / or different driving conditions.

[0012] In some embodiments, the electrically controlled clutch is an electromagnetic clutch, and a first electronic switch is arranged in a power supply circuit of the electromagnetic clutch and electrically connected to the electronic control unit.

[0013] In some embodiments, the pressure sensor is connected to the air tank or arranged in a connecting pipe between the air treatment unit and the air tank.

[0014] In some embodiments, when the system pressure collected by the pressure sensor reaches an unloading pressure threshold, the electronic control unit controls the valve passage and the exhaust valve to be opened; and when the system pressure is lower than a regeneration pressure threshold, the electronic control unit controls the valve passage and the exhaust valve to be closed.

[0015] In some embodiments, the regeneration pressure threshold is higher than a charging pressure threshold for controlling the air compressor to charge, and / or the electronic control unit determines the regeneration pressure threshold according to at least a charging parameter of the air compressor.

[0016] In some embodiments, the electrically controlled valve is an electromagnetic valve, and a second electronic switch is arranged in a power supply circuit of the electromagnetic valve and electrically connected to the electronic control unit.

[0017] In some embodiments, when the second electronic switch is closed, the valve passage is opened; and when the second electronic switch is opened, the valve passage is closed.

[0018] According to another aspect of the present invention, a control method for an air management system is provided, wherein the air management system is as described in any of the above embodiments. The control method includes: an electronic control unit monitoring the system pressure of the air management system via a pressure sensor; when the system pressure reaches an unloading pressure threshold, the electronic control unit controls the electronically controlled clutch to disengage, causing the air compressor to stop pumping air, and the electronic control unit controls the valve passage of the electronically controlled valve and the exhaust valve of the air handling unit to open, causing the air storage tank to blow air into the air handling unit; when the system pressure is lower than a regeneration pressure threshold, the electronic control unit controls the valve passage and the exhaust valve to close, causing the air storage tank to stop blowing air; when the system pressure is lower than a pumping pressure threshold, the electronic control unit controls the electronically controlled clutch to engage, causing the air compressor to pump air.

[0019] The beneficial effects of this invention compared to the prior art include at least the following:

[0020] This invention utilizes an electronically controlled clutch configured in an air compressor to control the unloading process of the air compressor based on electrical signals from an electronic control unit. On the one hand, it eliminates the need for a mechanical spring-structured unloading valve, simplifying the structural design of the air handling unit and facilitating its pipeline layout. On the other hand, the electronically controlled clutch can quickly respond to electrical signals and maintain sensitivity at all times.

On the other hand, the electrically controlled valve can quickly and accurately respond to electrical signals from the electronic control unit, controlling the opening and closing of the regeneration air path. This enables accurate and on-demand control of the air handling unit's regeneration process, unaffected by unloading time limitations, thus promoting energy conservation in the vehicle and preventing energy waste and increased air compressor load.

[0032] It should be noted that, unless otherwise specified, the embodiments of the present invention and the features in different embodiments can be combined with each other.

[0033] Figure 1 This diagram illustrates the main architecture of the air management system, for reference. Figure 1 As shown, the air management system 100 provided in this embodiment of the invention includes:

[0034] The electronic control unit 110 and pressure sensor 120 are electrically connected, and the air compressor 130, air handling unit 140 and air tank 150 are connected in sequence to form an air pumping path.

[0035] The air handling unit 140 does not have an unloading valve, a regeneration valve, or a regeneration cylinder; the air compressor 130 is equipped with an electronically controlled clutch 131, which is electrically connected to the electronic control unit 110.

[0036] The outlet of the air storage tank 150 is connected to the regeneration inlet of the air handling unit 140 via the valve channel 161 of the electronically controlled valve 160. The electronic control unit 110 is electrically connected to the electronically controlled valve 160 and the exhaust valve 144 of the air handling unit 140.

[0037] The electronic control unit 110 can be the vehicle's ECU (Electronic Control Unit) or a separate controller for the air management system 100.

[0038] This invention utilizes an electronically controlled clutch 131 configured in the air compressor 130 to control the unloading process of the air compressor 130 based on electrical signals from the electronic control unit 110. On the one hand, it eliminates the need for a mechanical spring structure in the unloading valve, simplifying the structural design of the air handling unit 140 and facilitating its pipeline layout. On the other hand, the electronically controlled clutch 131 can quickly respond to electrical signals and maintain sensitivity at all times. By controlling the disengagement and engagement of the electronically controlled clutch 131 through electrical signals, the unloading and inflation of the air compressor 130 can be controlled, achieving precise and stable control of the unloading state of the air compressor 130.

[0039] Specifically, when the electronically controlled clutch 131 engages under the control of an electrical signal, the air compressor 130 pumps air; when the electronically controlled clutch 131 disengages under the control of an electrical signal, the air compressor 130 stops pumping air, thereby unloading. During the pumping phase, the compressed gas generated by the air compressor 130 is filtered, cleaned, and treated by the air treatment unit 140 before being stored in the air storage tank 150.

[0040] This invention utilizes an air reservoir 150 as a regeneration air source and sets up an electronically controlled valve 160 to form a regeneration air path that connects the air outlet of the air reservoir 150 to the regeneration inlet of the air handling unit 140 via the valve channel 161 of the electronically controlled valve 160, and further (via the internal processing chamber of the air handling unit 140) to its exhaust valve 144. On the one hand, this simplifies the structural design of the air handling unit 140, eliminating the need for a mechanical spring structure regeneration valve and a separate regeneration reservoir, making the air management system 100 simple in structure, reducing costs, and facilitating its layout. On the other hand, the electronically controlled valve 160 can quickly and accurately respond to electrical signals from the electronic control unit 110, controlling the opening and closing of the regeneration air path, achieving accurate and on-demand control of the regeneration process of the air handling unit 140, without being limited by unloading time, which is beneficial for overall vehicle energy saving, avoiding energy waste and increasing the load rate of the air compressor 130.

[0041] During the regeneration phase, compressed air in the air reservoir 150 is back-blown towards the air handling unit 140, removing impurities such as oil and water adsorbed within the internal processing chamber of the air handling unit 140, thus regenerating the air handling unit 140 and preventing it from becoming saturated. Furthermore, residual gas between the air compressor 130 and the air handling unit 140 can be discharged through the exhaust valve 144 of the air handling unit 140.

[0042] Therefore, the air management system 100 of the present invention can achieve precise, stable, convenient and on-demand control of the unloading process of the air compressor 130 and the regeneration process of the air handling unit 140, and simplifies the structural design, facilitates pipeline layout, promotes energy saving of the whole vehicle, reduces the cost of the whole vehicle, and is easy to promote and use.

[0043] In some embodiments, when the system pressure collected by the pressure sensor 120 reaches the unloading pressure threshold, the electronic control unit 110 controls the electronically controlled clutch 131 to disengage; when the system pressure collected by the pressure sensor 120 is lower than the inflation pressure threshold, the electronic control unit 110 controls the electronically controlled clutch 131 to engage.

[0044] The unloading pressure threshold can be a fixed value or adjustable based on different vehicle models and driving conditions. For example, the electronic control unit 110 can pre-store unloading pressure thresholds corresponding to different vehicle models and / or different driving conditions, including starting, acceleration, hill climbing, and steering. During vehicle operation, the electronic control unit 110 can determine the corresponding unloading pressure threshold based on the vehicle's model parameters and the current driving condition, and control the unloading of the air compressor 130 via the electronically controlled clutch 131. In this way, the electronic control unit 110 can adjust the unloading pressure threshold as needed to adapt to specific application scenarios and reduce overall vehicle energy consumption.

[0045] Similarly, the inflation pressure threshold can be a fixed value or adjusted according to different vehicle models and driving conditions. For example, the electronic control unit 110 can pre-store inflation pressure thresholds corresponding to different vehicle models and / or different driving conditions. During vehicle operation, the electronic control unit 110 can determine the corresponding inflation pressure threshold based on the vehicle's model parameters and the current driving conditions, and control the air compressor 130 to inflate the vehicle via the electronic clutch 131. In this way, the electronic control unit 110 can adjust the inflation pressure threshold as needed to adapt to specific application scenarios and reduce overall vehicle energy consumption.

[0046] In some embodiments, when the system pressure collected by the pressure sensor 120 reaches the unloading pressure threshold, the electronic control unit 110 also controls the valve channel 161 and the exhaust valve 144 to open; when the system pressure collected by the pressure sensor 120 is lower than the regeneration pressure threshold, the electronic control unit 110 controls the valve channel 161 and the exhaust valve 144 to close.

[0047] When the system pressure reaches the unloading pressure threshold, the air pressure inside the air reservoir 150 is sufficient, and the air pumping circuit is not working at this time. This is suitable for backflushing and regenerating the air handling unit 140, and for removing the residual gas between the air compressor 130 and the air handling unit 140. When the system pressure falls below the regeneration pressure threshold, the regeneration process ends.

[0048] The regeneration pressure threshold is higher than the air compressor pressure threshold used to control the air compressor 130 to pump air. That is, the regeneration process can end earlier than the unloading process, and the regeneration time is not limited by the unloading time, so as to avoid wasting energy and avoid increasing the load rate of the air compressor 130.

[0049] Furthermore, the electronic control unit 110 can determine the regeneration pressure threshold based on the air compressor 130's inflation parameters. For example, the electronic control unit 110 can pre-store a functional relationship between regeneration time and inflation time to determine the required regeneration time based on each inflation time. Similarly, the electronic control unit 110 can pre-store a functional relationship between regeneration air volume and inflation air volume to determine the required regeneration air volume based on each inflation air volume. In addition to the air compressor 130's inflation parameters, the electronic control unit 110 can also determine the regeneration pressure threshold based on vehicle system pressure, application conditions, and other factors. This enables intelligent regeneration as needed, reducing unnecessary compressed air consumption and achieving energy savings for the entire vehicle.

[0050] Figure 2 This diagram illustrates a specific implementation structure of an air management system, combined with... Figure 1 and Figure 2As shown, in some embodiments, the electronically controlled clutch 131 is an electromagnetic clutch, and a first electronic switch 171 is provided in the power supply circuit of the electromagnetic clutch. The first electronic switch 171 is electrically connected to the electronic control unit 110.

[0051] The electromagnetic clutch achieves engagement and disengagement between friction plates through electromagnetic attraction. When the first electronic switch 171 is closed, the coil of the electromagnetic clutch is energized, generating a magnetic attraction, thereby engaging the friction plates and putting the air compressor 130 into the pumping state, with the pumping air path (air compressor 130 → air handling unit 140 → air tank 150) operating; when the first electronic switch 171 is opened, the coil of the electromagnetic clutch is de-energized, the friction plates disengage, the air compressor 130 stops pumping air, and enters the unloading state.

[0052] Traditional clutches engage and disengage under the control of pneumatic signals, which suffers from slow response due to decreased sensitivity with use. This invention employs an electromagnetic clutch that uses an energized coil to generate a magnetic attraction, enabling rapid and precise response based on electrical signal control.

[0053] In other embodiments, the electronically controlled clutch 131 may also adopt other electronic control forms, as long as it can achieve engagement and disengagement under the action of an electrical signal.

[0054] In some embodiments, the electrically controlled valve 160 is a solenoid valve, and a second electronic switch 172 is provided in the power supply circuit of the solenoid valve. The second electronic switch 172 is electrically connected to the electronic control unit 110.

[0055] The solenoid valve has the advantages of fast response, high precision, stability and durability, thus realizing precise and efficient control of the regeneration gas path from the air storage tank 150 to the air handling unit 140 based on electrical signals.

[0056] The solenoid valve can operate when the second electronic switch 172 is closed, opening the valve passage 161; when the second electronic switch 172 is open, the valve passage 161 is closed. Depending on different design requirements, the solenoid valve can also operate when the second electronic switch 172 is open.

[0057] In other embodiments, the electrically controlled valve 160 may also adopt other electrically controlled forms, as long as it can realize the opening and closing of the valve channel 161 under the action of an electrical signal.

[0058] In the above embodiments, the pressure sensor 120 can be connected to the air reservoir 150, or installed in the connecting pipe between the air handling unit 140 and the air reservoir 150, to detect the system pressure of the air management system 100. The system pressure mainly refers to the pressure of the air reservoir 150.

[0059] This invention also provides a control method for an air management system, implemented based on the air management system described in any of the above embodiments. The features and principles of the air management systems described in the above embodiments can be applied to the control method embodiments below. In the following control method embodiments, the features and principles of the air management system already explained will not be repeated.

[0060] Figure 3 This diagram illustrates the main steps of the air management system's control method, with reference to... Figure 3 and combined Figure 1 and Figure 2 As shown, the control method for the air management system provided in this embodiment of the invention includes:

[0061] S310, the electronic control unit 110 monitors the system pressure of the air management system 100 via the pressure sensor 120;

[0062] S320, when the system pressure reaches the unloading pressure threshold, the electronic control unit 110 controls the electronic control clutch 131 to disengage, causing the air compressor 130 to stop pumping air, and the electronic control unit 110 controls the valve passage 161 of the electronic control valve 160 and the exhaust valve 144 of the air handling unit 140 to open, causing the air tank 150 to blow air into the air handling unit 140.

[0063] S330, when the system pressure is lower than the regeneration pressure threshold, the electronic control unit 110 controls the valve channel 161 and the exhaust valve 144 to close, so that the air storage tank 150 stops blowing air;

[0064] S340, when the system pressure is lower than the air pressure threshold, the electronic control unit 110 controls the electronic clutch 131 to engage, so that the air compressor 130 pumps air.

[0065] The unloading pressure threshold, regeneration pressure threshold, and inflation pressure threshold can be flexibly varied according to vehicle model parameters, vehicle operating conditions, and other factors. The regeneration pressure threshold is usually higher than the inflation pressure threshold to avoid excessive energy waste caused by using too much compressed gas for regeneration.

[0066] Figure 4 This diagram illustrates a specific implementation flow of the control method for an air management system, with reference to... Figure 4 and combined Figures 1 to 3 As shown, in some embodiments, the control method of the air management system may specifically include the following process. Each judgment and control step may be executed by the electronic control unit, and will not be repeated in the following description.

[0067] S410, the air compressor pumps air, and the compressed air is processed by the air handling unit and stored in the air tank.

[0068] S420: Determine if the current system pressure has reached the unloading pressure threshold. If yes, proceed to the next step; otherwise, the air compressor continues to pump air. When the system pressure has not reached the unloading pressure threshold, the air compressor pumps air, while the pressure sensor monitors the system pressure in real time and sends the pressure signal back to the electronic control unit.

[0069] S430 controls the electronically controlled clutch to de-energize and disengage, causing the air compressor to stop pumping air and enter an unloading state. When the system pressure reaches the unloading pressure threshold, the electronic control unit controls the first electronic switch to open, thus de-energizing and disengaging the electronically controlled clutch.

[0070] S440 controls the opening of the valve passages of the exhaust valve and the electronically controlled valve, allowing the gas in the air reservoir to be backflushed into the air handling unit for regeneration. Simultaneously, residual gas between the air compressor and the air handling unit is also discharged through the exhaust valve.

[0071] S450: Determine if the current system pressure is lower than the regeneration pressure threshold. If yes, proceed to the next step; otherwise, the electronically controlled valve will not operate.

[0072] S460 controls the closure of the valve passage and exhaust valve of the electronically controlled valve, stopping the regeneration gas circuit from operating. When the electronic control unit detects that the system pressure is lower than the regeneration pressure threshold, it controls the second electronic switch in the regeneration circuit to open, thereby ending the regeneration process and closing the exhaust valve.

[0073] S470: Determine if the current system pressure is lower than the inflation pressure threshold. If yes, proceed to the next step; otherwise, de-energize the electronic clutch.

[0074] S480 controls the electronic clutch to engage, putting the air compressor into pumping mode. As the vehicle pressure decreases, when the system pressure falls below the pumping pressure threshold, the first electronic switch closes, energizing the electronic clutch to engage and restarting the air compressor.

[0075] In summary, this invention enables precise, stable, convenient, and on-demand control of the unloading process of the air compressor and the regeneration process of the air handling unit. It also simplifies structural design, facilitates pipeline layout, promotes energy saving in the vehicle, reduces vehicle costs, and is easy to promote and use.

[0076] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
