[0087] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0088] The present application aims to solve at least one of the technical problems existing in the related art. To this end, the present application proposes an air supply system, an integrated valve, a control method for the air supply system, and a vehicle, which can reduce the startup frequency of the air source.

[0089] Reference below Figures 1-13 A gas supply system 1 according to an embodiment of the present application is described.

[0090] like Figure 1 and Figure 2 As shown, the gas supply system 1 includes a first execution unit 10, a second execution unit 20, an air source 30, a central air circuit 40, a first subsystem branch 50 and a second subsystem branch 60, wherein the central air circuit 40 is connected to the air source 30, the first subsystem branch 50 includes a first air storage device 510, the first subsystem branch 50 is used to supply air to the first execution unit 10, and can be selectively connected to the central air circuit 40, the second subsystem branch 60 includes a second air storage device 610, the second subsystem branch 60 is used to supply air to the second execution unit 20, and can be selectively connected to the central air circuit 40.

[0091] In this embodiment, the gas supply system 1 is mainly used to provide a power source or working medium for equipment or functions that require compression of specific gases. The gas supply system 1 can integrate multiple subsystems and perform gas generation, storage, regulation, distribution and control, thereby driving the actuator to complete specific actions or provide the required gas for a specific process.

[0092] The gas source controller 90 of the gas supply system 1 is electrically connected to the gas source 30. The gas source 30 is mainly used to provide gas with a specific flow rate and pressure required by the gas supply system 1. For example, the gas source 30 includes but is not limited to an air pump and a compressor. The gas source controller 90 is mainly used to control the operation of the gas source 30.

[0093] The gas source 30 is connected to the central gas circuit 40, and the first subsystem branch 50 and the second subsystem branch 60 are respectively connected to the central gas circuit 40 and are independent of each other. The central gas circuit 40 is the main pipeline connecting the gas source 30 and the various subsystem branches in the gas supply system 1, and has the function of transporting and distributing gas. Compared with the subsystem branches connected between the central gas circuit 40 and the various execution units, the pipeline of the central gas circuit 40 has a larger diameter and is more resistant to high pressure.

[0094] The subsystem branches branch out from the central gas circuit 40, are connected to each execution unit one by one, and are equipped with control and adjustment elements. The subsystem branches are mainly used to further distribute and adjust the gas from the central gas circuit 40 to meet the precise needs of specific subsystems.

[0095] In addition, the first subsystem branch 50 may include a first gas storage device 510, which is used to supply gas to the first execution unit 10 and can be selectively connected to the central gas circuit 40. The second subsystem branch 60 may include a second gas storage device 610, which is used to supply gas to the second execution unit 20 and can be selectively connected to the central gas circuit 40.

[0096] In other words, the first subsystem branch 50 can supply air to the first execution unit 10 when it is connected to the central air circuit 40, and the first subsystem branch 50 can also supply air to the first execution unit 10 through the first air storage device 510 when it is not connected to the central air circuit 40. The second subsystem branch 60 can supply air to the second execution unit 20 when it is connected to the central air circuit 40, and the second subsystem branch 60 can also supply air to the second execution unit 20 through the second air storage device 610 when it is not connected to the central air circuit 40.

[0097] The central gas circuit 40, the first subsystem branch 50 and the second subsystem branch 60 may be connected in a variety of ways, including but not limited to:

[0098] In example 1, the central gas circuit 40 is connected to the first subsystem branch 50 , the central gas circuit 40 is connected to the second subsystem branch 60 , and the first subsystem branch 50 is not connected to the second subsystem branch 60 .

[0099] In this embodiment, the gas generated by the gas source 30 flows through the central gas path 40 and then flows to the first subsystem branch 50 and the second subsystem branch 60 respectively. The gas flowing through the first subsystem branch 50 can supply gas to the first execution unit 10, or it can supply gas to the first gas storage device 510, and the gas flowing through the second subsystem branch 60 can supply gas to the second execution unit 20, or it can supply gas to the second gas storage device 610.

[0100] Example 2: The central gas circuit 40 is connected to the first subsystem branch 50 , the central gas circuit 40 is not connected to the second subsystem branch 60 , and the first subsystem branch 50 is not connected to the second subsystem branch 60 .

[0101] In this embodiment, the gas generated by the gas source 30 flows to the first subsystem branch 50 after flowing through the central gas path 40, wherein the gas flowing through the first subsystem branch 50 can supply gas to the first execution unit 10, or to the first gas storage device 510, and at the same time, the second gas storage device 610 can supply gas to the second execution unit 20.

[0102] Example 3: The central gas circuit 40 is not connected to the first subsystem branch 50 , the central gas circuit 40 is connected to the second subsystem branch 60 , and the first subsystem branch 50 is not connected to the second subsystem branch 60 .

[0103] In this embodiment, the gas generated by the gas source 30 flows to the second subsystem branch 60 after flowing through the central gas path 40, wherein the gas flowing through the second subsystem branch 60 can supply gas to the second execution unit 20, or to the second gas storage device 610, and at the same time, the first gas storage device 510 can supply gas to the first execution unit 10.

[0104] Example 4: the central gas circuit 40 is not connected to the first subsystem branch 50 , the central gas circuit 40 is not connected to the second subsystem branch 60 , and the first subsystem branch 50 is connected to the second subsystem branch 60 .

[0105] In this embodiment, the gas source 30 does not supply gas to the first execution unit 10 and the second execution unit 20. The first gas storage device 510 can supply gas to the first execution unit 10 and the second execution unit 20. The second gas storage device 610 can supply gas to the first execution unit 10 and the second execution unit 20.

[0106] Example 5: The central gas circuit 40 is not connected to the first subsystem branch 50 , the central gas circuit 40 is not connected to the second subsystem branch 60 , and the first subsystem branch 50 is not connected to the second subsystem branch 60 .

[0107] In this embodiment, the gas source 30 does not supply gas to the first execution unit 10 and the second execution unit 20 , the first gas storage device 510 can supply gas to the first execution unit 10 , and the second gas storage device 610 can supply gas to the second execution unit 20 .

[0108] It should be noted that the application scenarios of the air supply system 1 include but are not limited to vehicles, aerospace and industrial automation. Taking the application of the air supply system 1 to a vehicle as an example, the first execution unit 10 may include an air spring control part, and the second execution unit 20 may include a seat massage and adjustment part.

[0109] In related technologies, pneumatic systems for vehicle suspension, seat adjustment, and tire inflation, among other functions, are typically integrated into a common gas supply device to achieve modular air supply control. However, in most solutions, the air circuits of the various subsystems can only be integrated, not isolated. This is particularly true when the pressure requirements of the subsystems are inconsistent. Subsystems with lower pressure requirements within the integrated air circuits need to vent air to reduce their own air circuit pressures, resulting in increased activation frequency of the air source 30, leaving room for improvement.

[0110] The present application selectively connects the central gas circuit 40 with the first subsystem branch 50 and the second subsystem branch 60, respectively, to achieve integration and isolation of the subsystem branches in the gas supply system 1, thereby dynamically adjusting the gas circuit connection relationship within the gas supply system 1, and automatically adjusting the gas pressure output by the gas source 30 according to different working conditions. When the pressure requirements of the first subsystem branch 50 and the second subsystem branch 60 are consistent, the first subsystem branch 50 and the second subsystem branch 60 can both be connected to the central gas circuit 40 and share the gas provided by the gas source 30. When the pressure requirements of the first subsystem branch 50 and the second subsystem branch 60 are inconsistent, at least one of the first subsystem branch 50 and the second subsystem branch 60 can be disconnected from the central gas circuit 40. The subsystem branch disconnected from the central gas circuit 40 can be supplied with gas through the gas storage device, thereby achieving isolation of the different subsystem branches. In addition, the first subsystem branch 50 includes a first gas storage device 510, and the second subsystem branch 60 includes a second gas storage device 610. When the first subsystem branch 50 and the second subsystem branch 60 are connected to each other and are not connected to the central gas circuit 40, one gas storage device can supply gas to multiple subsystem branches, thereby realizing the comprehensive control of the gas source and pressure by the gas supply system 1, which helps to reduce the startup frequency of the gas source 30 and improve work efficiency.

[0111] According to the gas supply system 1 provided in the embodiment of the present application, the central gas path 40 can be selectively connected to the first subsystem branch 50 and the second subsystem branch 60 respectively, which can dynamically adjust the gas path connection relationship within the gas supply system 1, and also help to reduce the startup frequency of the gas source 30 and improve work efficiency.

At the same time, the first sub-control valve 530 and the first execution unit 10 may each include multiple first sub-control valves 530 and the first execution unit 10 are connected one-to-one, and the first sub-control valve 530 is connected between the corresponding first execution unit 10 and the first gas storage device 510.

[0117] Among them, when the second main control valve 620 and the second sub-control valve 630 are both open, the second execution unit 20 receives gas from the central gas path 40; when the second main control valve 620 is closed and the second sub-control valve 630 is open, the second execution unit 20 receives gas from the second gas storage device 610; when the second sub-control valve 630 is closed, the second execution unit 20 does not receive gas.

[0118] In some embodiments, as Figure 3 As shown, the first execution unit 10 includes a plurality of empty spring assemblies 110 , and the second ends of the plurality of first sub-control valves 530 are connected to corresponding empty spring assemblies 110 .

[0119] In this embodiment, the first execution unit 10 may include multiple empty spring assemblies 110, and the first sub-control valve 530 is connected to the empty spring assembly 110 in a one-to-one correspondence. In other words, the first end of the first sub-control valve 530 is connected to the first main control valve 520 and the first air storage device 510, and the second end of the first sub-control valve 530 is connected to the corresponding empty spring assembly 110.

[0120] Among them, the first execution unit 10 is the main actuator group in the gas supply system 1 that is directly related to the equipment function and driven by gas. The first execution unit 10 usually includes multiple execution components with the same or similar functions, such as the air spring assembly 110, and is managed by a unified control logic.

[0121] The air spring is a key suspension component between the bogie and the vehicle body. The air spring assembly 110 is a device that uses compressed air to elastically support the load and is a type of pneumatic actuator. The control functions of the air spring include air spring stiffness adjustment and vehicle height adjustment. The vehicle's air suspension system adjusts the pressure of multiple air spring assemblies 110 to achieve vehicle height adjustment or load balance. For example, during the driving of the vehicle, the chassis domain control can send the target pressure control requirement or stiffness adjustment requirement directly to the central integrated air source controller 90 after calculation based on vehicle load, road conditions, driving mode, vehicle status and other data. The air source controller 90 performs specific air spring airbag inflation and deflation operations or air spring stiffness adjustment operations according to the control requirements of the chassis domain control.

[0122] When the first main control valve 520 and the first sub-control valve 530 are both open, the air spring assembly 110 receives gas from the central air path 40. When the first main control valve 520 is closed and the first sub-control valve 530 is open, the air spring assembly 110 receives gas from the first air storage device 510. When the first sub-control valve 530 is closed, the air spring assembly 110 does not receive gas.

[0123] Compared with this solution, similar integrated solutions in related technologies are unable to efficiently and centrally control the air supply system, and there is a problem that when the air spring function is running, the central inflation and deflation function cannot be run at the same time, or there is a problem that multiple air spring assemblies in the whole vehicle cannot simultaneously execute the inflation and deflation of individual air spring assemblies, resulting in the problem that multiple air spring assemblies cannot coordinately control the vehicle body posture.

[0124] In some embodiments, as Figure 3 As shown, the air spring assembly 110 may include a first sub-airbag 111, a second sub-airbag 112, a stiffness control valve 113, an airbag exhaust valve 114 and an airbag pressure sensor 115, wherein the stiffness control valve 113 is installed between the first sub-airbag 111 and the second sub-airbag 112, the first end of the airbag exhaust valve 114 is connected to the second sub-airbag 112, the second end of the airbag exhaust valve 114 is used to communicate with the outside world, and the airbag pressure sensor 115 is used to detect the air pressure of the first sub-airbag 111 and the second sub-airbag 112.

[0125] In this embodiment, the empty spring assembly 110 includes multiple, such as an empty spring assembly 110 located at the left front of the vehicle, an empty spring assembly 110 located at the right front of the vehicle, an empty spring assembly 110 located at the left rear of the vehicle, and an empty spring assembly 110 located at the left rear of the vehicle.

[0126] Taking one of the empty spring assemblies 110 as an example, the empty spring assembly 110 may include a first sub-airbag 111, a second sub-airbag 112, a stiffness control valve 113, an airbag exhaust valve 114 and an airbag pressure sensor 115. When the stiffness control valve 113 is opened, the first sub-airbag 111 and the second sub-airbag 112 are in a connected state. When the stiffness control valve 113 is closed, the first sub-airbag 111 and the second sub-airbag 112 are in an isolated state, and the airbag exhaust valve 114 is connected to the second sub-airbag 112. When the airbag exhaust valve 114 is opened, the high-pressure gas in the second sub-airbag 112 is discharged into the atmosphere.

[0127] Among them, the first sub-airbag 111 and the second sub-airbag 112 are two independent air chambers inside the empty spring assembly 110, and the positional relationship between the first sub-airbag 111 and the second sub-airbag 112 is not limited. For example, the first sub-airbag 111 can be the upper airbag and the second sub-airbag 112 can be the lower airbag, or the first sub-airbag 111 can be the lower airbag and the second sub-airbag 112 can be the upper airbag. The first sub-airbag 111 and the second sub-airbag 112 are connected by a stiffness control valve 113. The stiffness control valve 113 mainly changes the overall elasticity by controlling the gas flow between the first sub-airbag 111 and the second sub-airbag 112, thereby performing segmented stiffness adjustment. In addition, when one airbag fails, the other airbag can still provide partial support, thereby improving the safety performance of the empty spring assembly 110.

[0128] The airbag exhaust valve 114 is mainly used to control the connection between the second sub-airbag 112 and the outside world, which helps to quickly release the gas in the airbag to achieve height reduction or emergency exhaust. The airbag pressure sensor 115 is a device for real-time monitoring of the internal pressure of the first sub-airbag 111 and the second sub-airbag 112. It can provide feedback signals to the control system to achieve closed-loop control to maintain the set height or stiffness. The airbag pressure sensor 115 can also perform fault diagnosis.

[0129] In addition, the first end of the airbag exhaust valve 114 is connected to the second sub-airbag 112, the second end of the airbag exhaust valve 114 is used to communicate with the outside world, and the second sub-airbag 112 is connected to the second end of the first sub-control valve 530, that is, the second sub-airbag 112 is respectively connected to the second end of the first sub-control valve 530 and the first end of the airbag exhaust valve 114.

[0130] In some embodiments, as Figure 3 As shown, the second execution unit 20 may include a plurality of seat airbags 210 , and the second ends of the plurality of second sub-control valves 630 are connected to the corresponding seat airbags 210 .

[0131] In this embodiment, the second execution unit 20 may include multiple seat air bags 210, and the second sub-control valve 630 is connected to the seat air bags 210 in a one-to-one correspondence. In other words, the first end of the second sub-control valve 630 is connected to the second main control valve 620 and the second air storage device 610, and the second end of the second sub-control valve 630 is connected to the corresponding seat air bag 210.

[0132] Among them, the second execution unit 20 is the main actuator group in the air supply system 1 that is directly related to the equipment function and driven by gas. The second execution unit 20 usually includes multiple execution components with the same or similar functions, such as seat airbags 210, and is managed by a unified control logic.

[0133] The seat airbag 210 is a sealed airbag made of flexible materials such as rubber or polyurethane-coated fabric. The seat airbag 210 mainly changes its shape or hardness by inflation and deflation to achieve dynamic adjustable support, thereby optimizing the riding experience. The massage and adjustment functions of the seat airbag 210 include a seat massage function and a seat adjustment function. The seat massage function includes a driver's seat massage function and a passenger's seat massage function. The seat adjustment function includes a driver's seat lumbar support adjustment function, a passenger's seat lumbar support adjustment function, a driver's seat wing adjustment function, and a passenger's seat wing adjustment function. For example, according to the seat massage requirements, different combinations of inflation control or different combinations of deflation control are performed on the airbags located at the massage points of the driver's seat or the passenger's seat, thereby realizing the seat massage function. For example, according to the seat adjustment requirements, the lumbar support and side wing airbags of the driver's seat or the passenger's seat are inflated or deflated, and after the inflation control or deflation control is completed, the pressure of the lumbar support and side wing airbags is maintained, thereby realizing the seat lumbar support or seat side wing adjustment function.

[0134] When the second main control valve 620 and the second sub-control valve 630 are both open, the seat airbag 210 receives gas from the central air path 40. When the second main control valve 620 is closed and the second sub-control valve 630 is open, the seat airbag 210 receives gas from the second air storage device 610. When the second sub-control valve 630 is closed, the seat airbag 210 does not receive gas.

[0135] In some embodiments, as Figure 3 As shown, the second subsystem branch 60 may further include an air bag exhaust valve 640 , a first end of the air bag exhaust valve 640 is connected to the second end of the second main control valve 620 , and a second end of the air bag exhaust valve 640 is used to communicate with the outside.

[0136] In this embodiment, the second subsystem branch 60 is a branch pipeline network in the air supply system 1 that is specifically used to supply air to the second execution unit 20, and belongs to the next-level distribution structure of the central air circuit 40. The air bag exhaust valve 640 is a valve installed at the end of the second subsystem branch 60, which is used to quickly discharge the gas in the seat air bag 210 to the outside atmosphere, thereby achieving the contraction or pressure release of the seat air bag 210.

[0137] In some embodiments, as Figure 6 As shown, the following states can be combined arbitrarily, wherein the first state, the second state and the third state are that the gas source 30 inflates the corresponding gas storage device through the central gas path 40, the fourth state, the fifth state and the sixth state are that the gas source 30 supplies gas to the corresponding execution unit through the central gas path 40 and the subsystem branch, and the seventh state and the eighth state are that the gas storage device cross-supplies gas to other subsystem branches.

The gas source 30 is used to supply gas to the first gas storage device 510 through the central gas circuit 40 and the first subsystem branch 50. For example, the gas generated by the gas source 30 flows to the first subsystem branch 50 after flowing through the central gas circuit 40, wherein the gas flowing through the first subsystem branch 50 can supply gas to the first gas storage device 510.

For example, after the gas generated by the gas source 30 flows through the central gas circuit 40, part of it flows to the first subsystem branch 50, and the other part flows to the second subsystem branch 60. The gas flowing through the first subsystem branch 50 can supply gas to the first gas storage device 510, and at the same time, the gas flowing through the second subsystem branch 60 can supply gas to the second gas storage device 610.

The gas flowing through the first subsystem branch 50 can supply gas to the first gas storage device 510, and at the same time, the gas flowing through the second subsystem branch 60 can supply gas to the second gas storage device 610.

[0149] In addition, a control valve can be provided between the central gas path 40 and the gas source 30, and the connection between the central gas path 40 and the gas source 30 is controlled by the opening and closing state of the control valve. In the first state to the sixth state, the control valve is open, and the central gas path 40 is connected to the gas source 30. In the seventh state and the eighth state, the control valve is closed, and the central gas path 40 is not connected to the gas source 30.

[0150] In some embodiments, as Figure 2 and Figure 6 As shown, the air supply system 1 further includes at least one third execution unit 70 and at least one third subsystem branch 80 , wherein the third execution unit 70 can be selectively connected to the central air circuit 40 through the corresponding third subsystem branch 80 .

[0151] In this embodiment, the third subsystem branch 80 can supply gas to the third execution unit 70 when it is connected to the central gas circuit 40. The third subsystem branch 80 is separated from the central gas circuit 40 and is connected to the third execution unit 70 one-to-one, and is equipped with a control and adjustment element. The third subsystem branch 80 is mainly used to further distribute and adjust the gas from the central gas circuit 40 to meet the precise needs of the third execution unit 70.

[0152] In some embodiments, as Figure 2 and Figure 6 As shown, the third subsystem branch 80 may include a third sub-control valve 810 , a first end of the third sub-control valve 810 is connected to the central gas path 40 , and a second end of the third sub-control valve 810 is connected to the corresponding third execution unit 70 .

[0153] In this embodiment, the third sub-control valve 810 and the third execution unit 70 can each include multiple ones, and the third sub-control valve 810 and the third execution unit 70 are connected one-to-one, wherein when the third sub-control valve 810 is opened, the third execution unit 70 receives gas from the central gas path 40, and when the third sub-control valve 810 is closed, the third execution unit 70 does not receive gas.

[0154] In some embodiments, as Figure 4 As shown, one of the third subsystem branches 80 includes an expansion control valve 820 , and a first end of the expansion control valve 820 is connected to the central gas line 40 .

[0155] In this embodiment, the third execution unit 70 corresponding to the third subsystem branch 80 including the expansion control valve 820 includes all other unmentioned gas-using systems 750 in the entire vehicle. When the expansion control valve 820 is in the open state, the gas source 30 supplies gas to the other gas-using systems 750.

[0156] It should be noted that the first end of the expansion control valve 820 is connected to the central air path 40, and the second end of the expansion control valve 820 can be connected to the corresponding third execution unit 70, or can be connected to other control valve groups. For example, the expansion control valve 820 can be directly connected to other gas systems 750 of the entire vehicle, or can be connected to other control valve groups through the expansion control valve 820, or can be connected to an expansion gas tank through the expansion control valve 820, thereby performing expansion control on other gas systems 750 of the entire vehicle.

[0157] In some embodiments, as Figure 4 and Figure 5 As shown, the third execution unit 70 includes at least one of the following:

[0158] The vehicle body water-floating airbag 710 , the camera demisting mechanism 720 , the rearview mirror air blowing device 730 and the wheel side assembly 740 are each selectively connected to the central air path 40 through the corresponding third subsystem branch 80 .

[0159] In other words, the air supply system 1 can also include: a vehicle body water floating airbag 710, a camera demisting mechanism 720, a rearview mirror air blowing device 730, a wheel side assembly 740 and multiple third subsystem branches 80, wherein the vehicle body water floating airbag 710, the camera demisting mechanism 720, the rearview mirror air blowing device 730 and the wheel side assembly 740 can be selectively connected to the central air path 40 through the corresponding third subsystem branches 80.

[0161] Among them, the vehicle body falling into water buoy control function is mainly realized through the inflation control of the vehicle body floating airbag 710. After the vehicle falls into water, the vehicle falling into water floating self-rescue system determines the falling situation and sends the control instruction of the vehicle body floating airbag 710 to the air source controller 90. The air source controller 90 performs emergency rapid air supply control on the vehicle body floating airbag 710, including opening the vehicle body floating airbag control valve 814, and comprehensively controlling all the compressed gas in the entire vehicle to quickly supply air to the vehicle body floating airbag 710, and at the same time inflating the central air path 40, thereby increasing the inflation amount of the vehicle body floating airbag 710 and increasing the volume of the vehicle body floating airbag 710, thereby increasing the displacement of the vehicle body floating airbag 710, so that the buoyancy provided by the vehicle body floating airbag 710 can lift the vehicle to float on the water surface.

[0162] The demisting control function of the vehicle camera is mainly realized through the camera demisting mechanism 720. When the air source controller 90 receives the camera demisting control instruction sent by the intelligent driving system or other systems of the vehicle, the air source controller 90 controls the camera demisting control valve 815 to open, and the air source 30 fills the air circuit of the demisting part of the vehicle camera with high-pressure gas, and then drives the camera demisting mechanism to operate 720 through the high-pressure gas, or by blowing high-pressure gas, removes water droplets, fog or other dirt attached to the lens of the intelligent driving or driving safety-related camera on the vehicle, thereby improving the image recognition performance related to the intelligent driving camera of the vehicle and the safety performance of the vehicle.

[0163] The de-mist control function of the exterior rearview mirror is mainly realized through the rearview mirror air blowing device 730. When the air source controller 90 receives the rearview mirror de-mist control command sent by the vehicle instrument, multimedia central control screen or rain sensing system, the air source controller 90 controls the rearview mirror de-mist control valve 816 to open, and combines the exterior rearview mirror air blowing device 730 to blow high-pressure gas to the rearview mirror to remove water droplets, fog or other dirt attached to the rearview mirror outside the vehicle, thereby improving the visibility of the exterior rearview mirror in rainy days and improving the safety of vehicle driving.

[0169] It should be noted that the functions running in the twelfth state are mainly functions that require fast response.

[0170] In some embodiments, as Figure 3-Figure 5 As shown, the second execution unit 20 includes a seat airbag 210, and the third execution unit 70 includes a vehicle body floating airbag 710 and a wheel side assembly 740;

[0173] In addition, the twelfth state corresponds to the vehicle body falling into water buoy control function is in the start state, in other words, after the vehicle falls into water, the vehicle falling into water floating self-rescue system determines the falling into water situation, sends the control instruction of the vehicle body floating airbag 710 to the air source controller 90, and the air source controller 90 performs emergency rapid air supply control on the vehicle body floating airbag 710, switches the air supply system 1 to the twelfth state, in which the third subsystem branch 80 corresponding to the vehicle body floating airbag 710 and the wheel side assembly 740 corresponding to the wheel side assembly 740 are activated. The third subsystem branch 80, the first subsystem branch 50, and the second subsystem branch 60 are all connected to the central air path 40. The first air storage device 510, the second air storage device 610, the wheel side assembly 740, the seat airbag 210, and the air source 30 are all used to supply air to the corresponding vehicle body floating airbag 710, thereby increasing the volume of the vehicle body floating airbag 710, thereby increasing the displacement of the vehicle body floating airbag 710, and further enabling the buoyancy provided by the vehicle body floating airbag 710 to lift the vehicle onto the water surface.

[0174] In some embodiments, as Figure 5 As shown, the third execution unit 70 includes a wheel side assembly 740, and the corresponding third sub-control valve 810 includes: a tire control valve 811, a tire deflation valve 812 and an external inflation valve 813, wherein the first end of the tire control valve 811 is connected to the central air path 40, the second end of the tire control valve 811 is connected to the corresponding wheel side assembly 740, the first end of the tire deflation valve 812 is connected to the first end of the tire control valve 811, the second end of the tire deflation valve 812 is connected to the outside world, the first end of the external inflation valve 813 is connected to the central air path 40, and the second end of the external inflation valve 813 is used to connect to the object to be inflated.

[0175] In this embodiment, the inflation and deflation control function of the wheel side assembly 740 is mainly realized through the wheel side assembly 740. The inflation and deflation control function of the wheel side assembly 740 includes a tire pressure adjustment function and an external inflation function. For example, the air source controller 90 performs the tire pressure adjustment function according to the tire pressure adjustment requirement, and can control the inflation and deflation of the vehicle's tires so that the actual tire pressure of the tire reaches the target tire pressure requirement. For example, the air source controller 90 performs the external inflation function according to the external inflation requirement, and can control the inflation of external inflated objects 742 such as air mattresses, footballs and spare tires. The external inflated objects 742 are external objects to be inflated.

[0176] In addition, the wheel rim assembly 740 may include multiple ones, such as a wheel rim assembly 740 located at the left front of the vehicle, a wheel rim assembly 740 located at the right front of the vehicle, a wheel rim assembly 740 located at the left rear of the vehicle, and a wheel rim assembly 740 located at the left rear of the vehicle.

[0177] Taking one of the wheel rim assemblies 740 as an example, the third sub-control valve 810 corresponding to the wheel rim assembly 740 includes at least a tire control valve 811, a tire deflation valve 812 and an external inflation valve 813, wherein the first end of the tire control valve 811 is connected to the central air circuit 40, the second end of the tire control valve 811 is connected to the corresponding wheel rim assembly 740, the first end of the tire deflation valve 812 is connected to the first end of the tire control valve 811, the second end of the tire deflation valve 812 is connected to the outside world, the first end of the external inflation valve 813 is connected to the central air circuit 40, and the second end of the external inflation valve 813 is used to connect to the object to be inflated.

[0178] In addition, the tire deflation valve 812 may include a tire quick release valve and a tire slow release valve.

[0179] When the wheel assembly 740 starts to control inflation and deflation, the air source 30 supplies air to the wheel assembly 740 through the central air circuit 40 and the third subsystem branch 80 corresponding to the wheel assembly 740. When the tire control valve 811 is opened and the tire deflation valve 812 is closed, the air source 30 inflates the tire 741. When the tire control valve 811 is closed and the tire deflation valve 812 is opened, the tire 741 is deflated. When the external inflation valve 813 is opened, the air source 30 inflates the external object 742.

[0180] In some embodiments, as Figure 2 and Figure 6 As shown, the air supply system 1 can also include an air source controller 90, and the control valves in each subsystem branch and each execution unit are solenoid valves.

[0182] The air source controller 90 is electrically connected to the CAN bus, where CAN is a controller area network. The air source controller 90 is configured to obtain the vehicle's driving signals and control signals through the CAN bus, and control the air source 30 and the solenoid valve based on the driving signals and control signals.

[0184] In addition, the gas source controller 90 can control the motor speed of the gas source 30 by controlling the operating power of the gas source 30, thereby controlling the output flow rate of the high-pressure gas output by the gas source 30. The smaller the power of the gas source 30, the smaller the output flow rate, and the smaller the output gas pressure.

[0185] When controlling the inflation of different systems, the gas source controller 90 controls the gas source 30 to operate in different power ranges, thereby controlling the system output corresponding gas pressure ranges, wherein the power range of the second execution unit 20 is smaller than the charging and discharging power range of the wheel side assembly 740, the charging and discharging power range of the wheel side assembly 740 is smaller than the control power range of the first execution unit 10, and the control power range of the first execution unit 10 is smaller than the control power range of simultaneous inflation of the first execution unit 10 and the second execution unit 20.

[0186] The air source controller 90, air source 30 and integrated valve in the system can each be an assembly part individually, or they can be integrated into an assembly part in pairs, or the three can be integrated into an assembly part together, and can be installed on the chassis, trunk, or front cabin of the vehicle.

[0187] In some embodiments, as Figure 2 and Figure 3 As shown, the air supply system 1 includes a plurality of air spring assemblies 110 and a plurality of seat air bags 210, an air source 30, a central air circuit 40, a first subsystem branch 50 and a second subsystem branch 60, wherein the central air circuit 40 is connected to the air source 30, the first subsystem branch 50 includes a first air storage device 510, the first subsystem branch 50 is used to supply air to the air spring assembly 110, and can be selectively connected to the central air circuit 40, the second subsystem branch 60 includes a second air storage device 610, the second subsystem branch 60 is used to supply air to the seat air bags 210, and can be selectively connected to the central air circuit 40.

[0190] The first subsystem branch 50 can supply air to the air spring assembly 110 when it is connected to the central air circuit 40, and the first subsystem branch 50 can also supply air to the air spring assembly 110 through the first air storage device 510 when it is not connected to the central air circuit 40. The second subsystem branch 60 can supply air to the seat air bag 210 when it is connected to the central air circuit 40, and the second subsystem branch 60 can also supply air to the seat air bag 210 through the second air storage device 610 when it is not connected to the central air circuit 40.

[0191] In some embodiments, as Figure 3 and Figure 6 As shown, the first subsystem branch 50 further includes: a first master control valve 520 and at least one first sub-control valve 530, wherein a first end of the first master control valve 520 is connected to the central air path 40, a second end of the first master control valve 520 is connected to a first end of the first sub-control valve 530 and the first air storage device 510, and a second end of the first sub-control valve 530 is connected to a corresponding air spring assembly 110;

[0193] Among them, when the first main control valve 520 and the first sub-control valve 530 are both open, the air spring assembly 110 receives gas from the central air path 40; when the first main control valve 520 is closed and the first sub-control valve 530 is open, the air spring assembly 110 receives gas from the first gas storage device 510; when the first sub-control valve 530 is closed, the air spring assembly 110 does not receive gas.

[0194] Among them, when the second main control valve 620 and the second sub-control valve 630 are both open, the seat airbag 210 receives gas from the central air path 40; when the second main control valve 620 is closed and the second sub-control valve 630 is open, the seat airbag 210 receives gas from the second air storage device 610; when the second sub-control valve 630 is closed, the seat airbag 210 does not receive gas.

[0196] In this embodiment, when the stiffness control valve 113 is opened, the first sub-airbag 111 and the second sub-airbag 112 are in a connected state; when the stiffness control valve 113 is closed, the first sub-airbag 111 and the second sub-airbag 112 are in an isolated state, and the airbag exhaust valve 114 is connected to the second sub-airbag 112; when the airbag exhaust valve 114 is opened, the high-pressure gas in the second sub-airbag 112 is discharged into the atmosphere.

[0197] Among them, the first sub-airbag 111 and the second sub-airbag 112 are two independent air chambers inside the air spring assembly 110, which are connected by a stiffness control valve 113. The stiffness control valve 113 mainly changes the overall elasticity by controlling the gas flow between the first sub-airbag 111 and the second sub-airbag 112, thereby performing segmented stiffness adjustment. In the event that one airbag fails, the other airbag can still provide partial support, thereby improving the safety performance of the air spring assembly 110.

[0198] The airbag exhaust valve 114 is mainly used to control the connection between the second sub-airbag 112 and the outside world, which helps to quickly release the gas in the airbag to achieve height reduction or emergency exhaust. The airbag pressure sensor 115 is a device for real-time monitoring of the internal pressure of the first sub-airbag 111 and the second sub-airbag 112. It can provide feedback signals to the control system to achieve closed-loop control to maintain the set height or stiffness. The airbag pressure sensor 115 can also perform fault diagnosis.

[0199] In some embodiments, as Figure 3 As shown, the second subsystem branch 60 may further include an air bag exhaust valve 640 , a first end of the air bag exhaust valve 640 is connected to the second end of the second main control valve 620 , and a second end of the air bag exhaust valve 640 is used to communicate with the outside.

[0200] In this embodiment, the second subsystem branch 60 is a branch pipeline network in the air supply system 1 that is specifically used to supply air to the second execution unit 20, and belongs to the next-level distribution structure of the central air circuit 40. The air bag exhaust valve 640 is a valve installed at the end of the second subsystem branch 60, which is used to quickly discharge the gas in the seat air bag 210 to the outside atmosphere, thereby achieving the contraction or pressure release of the seat air bag 210.

[0201] In some embodiments, as Figure 6 As shown, the gas supply system 1 also includes an integrated valve, the first subsystem branch 50 includes a first sub-gas circuit, the second subsystem branch 60 includes a second sub-gas circuit, and the integrated valve includes: a central gas circuit 40, a first sub-gas circuit and a second sub-gas circuit. The first subsystem branch 50 can be selectively connected to the central gas circuit 40 through the first sub-gas circuit, and the second subsystem branch 60 can be selectively connected to the central gas circuit 40 through the second sub-gas circuit.

[0202] In some embodiments, as Figure 6 As shown, the integrated valve also includes a plurality of valve cores, and the plurality of valve cores and the plurality of sub-gas paths are used to form a plurality of first-type subsystem control valve groups. The first-type subsystem control valve group is a control valve group connected to the gas storage device. The first-type subsystem control valve group includes a main control valve and a first-type sub-control valve. The first end of the main control valve is connected to the central gas path 40, and the second end of the main control valve is connected to the first end of the sub-control valve. There is a port for connecting to the gas storage device between the second end of the main control valve and the first end of the sub-control valve.

[0203] In some embodiments, as Figure 6 As shown, the plurality of gas circuits further form a second type of subsystem control valve group, which is connected to the central gas circuit 40 .

[0204] The present application also provides an integrated valve. Figure 6 As shown, the integrated valve includes a central gas path 40 and a plurality of sub-gas paths, and the plurality of sub-gas paths are selectively connected to the central gas path 40 .

[0206] In this embodiment, the gas supply system 1 includes an integrated valve composed of multiple control valve groups, and multiple gas paths are provided in the integrated valve. The gas supply system 1 controls the connectivity state of the gas paths in the integrated valve by adjusting the opening and closing states of the control valve groups in the integrated valve, thereby realizing the control of the entire gas supply system 1.

[0207] The multiple air paths within the integrated valve can form a central air path 40 and multiple first-class subsystem control valve groups, and the multiple first-class subsystem control valve groups are respectively connected to the central air path 40, and the multiple first-class subsystem control valve groups all include a main control valve and a first-class sub-control valve, wherein the first end of the main control valve is connected to the central air path 40, and the second end of the main control valve is connected to the first end of the sub-control valve, that is, the main control valve is connected between the central air path 40 and the sub-control valve, and at the same time, the second end of the sub-control valve is connected to the execution unit, and there is a port for connecting to the gas storage device between the second end of the main control valve and the first end of the sub-control valve, that is, the main control valve is also connected between the central air path 40 and the gas storage device.

[0208] When the main control valve is open and the sub-control valve is closed, the central air path 40 is connected to the air storage device. When the main control valve is open and the sub-control valve is open, the central air path 40 is connected to the air storage device and the execution unit at the same time.

[0209] For example, the first type of subsystem control valve group may include a main control valve and a first type of sub-control valve, wherein the main control valve may include a first main control valve 520 and a second main control valve 620 , and the first type of sub-control valve may include a first sub-control valve 530 and a second sub-control valve 630 .

[0210] In some embodiments, as Figure 6 As shown, the plurality of gas circuits further form a second type of subsystem control valve group, which is connected to the central gas circuit 40 .

[0211] In this embodiment, the multiple air paths within the integrated valve can also form a second-type subsystem control valve group, and the multiple second-type subsystem control valve groups are respectively connected to the central air path 40. The second-type subsystem control valve group is a control valve group that is not connected to the air storage device, wherein the first end of the second-type subsystem control valve group is connected to the central air path 40, and the second end of the second-type subsystem control valve group is connected to the execution unit. When the second-type subsystem control valve group is opened, the central air path 40 is connected to the execution unit.

[0212] For example, the second type of subsystem control valve group may include a third sub-control valve 810 .

[0213] The embodiment of the present application further provides a control method for the gas supply system 1, comprising:

[0214] Based on the working state of the first execution unit 10, the working state of the second execution unit 20, the pressure of the first gas storage device 510 and the pressure of the second gas storage device 610, the connection state of the first subsystem branch 50 and the second subsystem branch 60 with the central gas path 40 is controlled.

[0215] In some embodiments, as Figure 8 As shown, the control method of the gas supply system 1 includes: controlling the communication state of the first subsystem branch 50 and the second subsystem branch 60 with the central gas path 40 based on at least one of the working state of the first execution unit 10, the working state of the second execution unit 20, the pressure of the first gas storage device 510, and the pressure of the second gas storage device 610, including:

[0216] When it is determined that the pressure of the first gas storage device 510 is not less than the first target value, the first subsystem branch 50 is disconnected from the central gas circuit 40, and the first gas storage device 510 is used to supply gas to the corresponding first execution unit 10; and / or

[0217] When it is determined that the pressure of the second gas storage device 610 is not less than the second target value, the second subsystem branch 60 is controlled to be disconnected from the central gas circuit 40 , and gas is supplied to the corresponding second execution unit 20 through the second gas storage device 610 .

[0218] In some embodiments, as Figure 8 As shown, the control method of the gas supply system 1 includes: when it is determined that the pressure of the first gas storage device 510 is less than the first target value, controlling the gas source 30 to start, controlling the first subsystem branch 50 to communicate with the central gas path 40 to inflate the first gas storage device 510; and / or,

[0219] When it is determined that the pressure of the second gas storage device 610 is less than the second target value, the control gas source 30 is started to control the second subsystem branch 60 to be connected to the central gas path 40 to inflate the second gas storage device 610 .

[0220] In this embodiment, the pressure of the first gas storage device 510 is defined as not being less than the first target value, and the first gas storage device 510 is in a full gas state. When the pressure of the first gas storage device 510 is less than the first target value, the first gas storage device 510 is in an inflated state. The pressure of the second gas storage device 610 is defined as not being less than the second target value, and the second gas storage device 610 is in a full gas state. When the pressure of the second gas storage device 610 is less than the second target value, the second gas storage device 610 is in an inflated state.

[0221] During actual operation, after the gas supply system 1 is powered on and started, it determines whether the pressure of at least one of the first gas storage device 510 and the second gas storage device 610 meets the target value preset by the gas supply system 1. When it is determined that the pressure of the first gas storage device 510 is less than the first target value, the first gas storage device 510 is in an inflated state, and the gas supply system 1 controls the gas source 30 to start, and controls the first subsystem branch 50 to be connected to the central gas path 40 to inflate the first gas storage device 510.

[0222] When it is determined that the pressure of the second gas storage device 610 is less than the second target value, the second gas storage device 610 is in an inflated state, and the gas supply system 1 controls the gas source 30 to start, and controls the second subsystem branch 60 to be connected to the central gas path 40 to inflate the second gas storage device 610.

[0223] Among them, the first gas storage device 510 and the second gas storage device 610 can reach a full gas state after the inflation process, or they can be in a full gas state as soon as they are turned on. After the first gas storage device 510 is in a full gas state, the pressure of the first gas storage device 510 is not less than the first target value, and the first subsystem branch 50 is controlled to be disconnected from the central gas line 40, thereby ending the inflation of the first gas storage device 510. After the second gas storage device 610 is in a full gas state, the pressure of the second gas storage device 610 is not less than the second target value, and the second subsystem branch 60 is controlled to be disconnected from the central gas line 40, thereby ending the inflation of the second gas storage device 610.

[0224] In addition, when it is determined that the pressure of the first air storage device 510 is less than the first target value and the pressure of the second air storage device 610 is less than the second target value, the control air source 30 is started, the first subsystem branch 50 is controlled to be connected to the central air circuit 40 to inflate the first air storage device 510, and the second subsystem branch 60 is controlled to be connected to the central air circuit 40 to inflate the second air storage device 610.

[0225] In other words, after the system is powered on and started, it is first determined whether the air pressure values ​​of the first air storage device 510 and the second air storage device 610 meet the preset pressure requirements of the system;

[0226] If it is determined that the air pressure value in the first air storage device 510 does not meet the preset pressure requirement of the system, and the air pressure value in the second air storage device 610 meets the preset pressure requirement of the system, the system controls the air source 30 to start and control the inflation of the first air storage device 510;

[0227] If it is determined that the air pressure value in the first air storage device 510 meets the preset pressure requirement of the system, and the air pressure value in the second air storage device 610 does not meet the preset pressure requirement of the system, the system controls the air source 30 to start and controls the inflation of the second air storage device 610;

[0228] If it is determined that the air pressure values ​​in the first air storage device 510 and the second air storage device 610 do not meet the preset pressure requirements of the system, the system controls the air source 30 to start and simultaneously controls the inflation of the first air storage device 510 and the second air storage device 610;

[0229] If it is determined that the air pressure values ​​in the first air storage device 510 and the second air storage device 610 both meet the preset pressure requirements of the system, the system directly enters the dormant state and waits for the execution instruction of the corresponding function.

[0230] In addition, when the gas source 30 inflates the first gas storage device 510, the first subsystem branch 50 is connected to the central gas circuit 40. If the first execution unit 10 also has an inflation demand, the first execution unit 10 is connected to the first subsystem branch 50, and the gas source 30 can inflate the first gas storage device 510 and the first execution unit 10 at the same time. If the first execution unit 10 has no inflation demand, the first execution unit 10 is disconnected from the first subsystem branch 50, and the gas source 30 can only inflate the first gas storage device 510.

[0231] When the first gas storage device 510 is fully inflated, the first subsystem branch 50 is disconnected from the central gas path 40 , and the first gas storage device 510 inflates the first execution unit 10 .

[0232] When the gas source 30 inflates the second gas storage device 610, the second subsystem branch 60 is connected to the central gas path 40. If the second execution unit 20 also has an inflation demand, the second execution unit 20 is connected to the second subsystem branch 60, and the gas source 30 can inflate the second gas storage device 610 and the second execution unit 20 at the same time. If the second execution unit 20 has no inflation demand, the second execution unit 20 is disconnected from the second subsystem branch 60, and the gas source 30 can only inflate the second gas storage device 610.

[0233] When the second gas storage device 610 is fully inflated, the second subsystem branch 60 is disconnected from the central gas path 40 , and the second gas storage device 610 inflates the second execution unit 20 .

[0234] In some embodiments, the gas supply system 1 includes: a first-type subsystem branch and a second-type subsystem branch, the first-type subsystem branch includes a gas storage device, and the second-type subsystem branch does not include a gas storage device;

[0235] Controlling the connection between the first subsystem branch 50 and the second subsystem branch 60 and the central gas path 40 based on at least one of the working state of the first execution unit 10, the working state of the second execution unit 20, the pressure of the first gas storage device 510, and the pressure of the second gas storage device 610 includes:

[0236] When it is determined that the gas source 30 is one of the first and second subsystem branches, the startup instruction corresponding to the execution unit corresponding to the other subsystem branch is not executed temporarily.

[0237] For example, when the third subsystem branch 80 corresponding to the wheel side assembly 740 is in the inflation function, the inflation instruction corresponding to at least one of the first air storage device 510 and the second air storage device 610 is temporarily not executed.

[0238] Among them, when the air source 30 supplies air to the wheel side assembly 740 of the third subsystem branch 80, when an inflation instruction corresponding to at least one of the first air storage device 510 and the second air storage device 610 is received, the first subsystem branch 50 and / or the second subsystem branch 60 are temporarily not started.

[0239] For another example, when the air source 30 supplies air to at least one of the first air storage device 510 and the second air storage device 610 , the start-up instruction corresponding to the wheel side assembly 740 is temporarily not executed.

[0240] Among them, when receiving the start instruction corresponding to the wheel side assembly 740 corresponding to the third subsystem branch 80, when the gas source 30 supplies gas to the first subsystem branch 50, the wheel side assembly 740 corresponding to the third subsystem branch 80 is temporarily not started. After the gas source 30 completes the gas supply to the first gas storage device 510 of the first subsystem branch 50, the first execution unit 10 is supplied with gas through the first gas storage device 510. When the gas source 30 supplies gas to the second subsystem branch 60, the wheel side assembly 740 corresponding to the third subsystem branch 80 is temporarily not started. When the gas source 30 supplies gas to the second gas storage device 610 of the second subsystem branch 60, the first execution unit 10 is supplied with gas. After the air supply is completed, air is supplied to the second execution unit 20 through the second air storage device 610. When the air source 30 supplies air to the first subsystem branch 50 and the second subsystem branch 60, the wheel side assembly 740 corresponding to the third subsystem branch 80 is temporarily not started. After the air source 30 completes the air supply to the first air storage device 510 of the first subsystem branch 50 and the second air storage device 610 of the second subsystem branch 60, air is supplied to the first execution unit 10 through the first air storage device 510, and air is supplied to the second execution unit 20 through the second air storage device 610, and then the wheel side assembly 740 corresponding to the third subsystem branch 80 is started.

[0241] In some embodiments, as Figure 9 and Figure 12 As shown, the first type of subsystem branch includes a first subsystem branch 50 and a second subsystem branch 60, the second type of subsystem branch includes a third subsystem branch 80, and the air supply system 1 includes a wheel side assembly 740 and the corresponding third subsystem branch 80;

[0242] When it is determined that the air source 30 is one of the first and second subsystem branches, the startup instructions corresponding to the execution unit corresponding to the other subsystem branch will not be executed temporarily, including: the wheel side assembly 740 performs the inflation function through the corresponding third subsystem branch 80, and the startup instructions corresponding to the first execution unit 10 and the second execution unit 20 will not be executed temporarily.

[0243] In some embodiments, as Figure 9 and Figure 12 As shown, the control method of the air supply system 1 includes: when the air supply system 1 includes a wheel side assembly 740 and a corresponding third subsystem branch 80, and receives a start instruction corresponding to at least one of the first execution unit 10 and the second execution unit 20, determining whether the third subsystem branch 80 corresponding to the wheel side assembly 740 is performing an inflation function;

[0244] When the wheel assembly 740 performs the inflation function through the corresponding third subsystem branch 80 , the first execution unit 10 and the second execution unit 20 are suspended.

[0245] In this embodiment, after the air supply system 1 receives a start-up instruction corresponding to at least one of the first execution unit 10 and the second execution unit 20, it determines the pressure of the corresponding air storage device in real time, and uses the corresponding air storage device to supply air when the pressure of the air storage device is not less than the target value, and enters the corresponding control state. For example, after the air supply system 1 receives a start-up instruction corresponding to the first execution unit 10, it determines the pressure of the first air storage device 510 in real time, and uses the first air storage device 510 to supply air when the pressure of the first air storage device 510 is not less than the first target value, thereby starting the control function of the air spring. For another example, after the air supply system 1 receives a start-up instruction corresponding to the second execution unit 20, it determines the pressure of the second air storage device 610 in real time, and uses the second air storage device 610 to supply air when the pressure of the second air storage device 610 is not less than the second target value, thereby starting the massage and adjustment function of the seat air bag 210.

[0246] Among them, when the air supply system 1 includes a wheel side assembly 740 and a corresponding third subsystem branch 80, no matter whether the air supply system 1 receives an inflation instruction corresponding to the first air storage device 510 or receives an inflation instruction corresponding to the second air storage device 610, it is necessary to first determine whether the third subsystem branch 80 corresponding to the wheel side assembly 740 is performing the inflation function.

[0247] When the third subsystem branch 80 corresponding to the wheel side assembly 740 is performing the inflation function, the start-up instructions corresponding to the first execution unit 10 and the second execution unit 20 are temporarily not executed. After the inflation function of the third subsystem branch 80 corresponding to the wheel side assembly 740 is completed, the pressure of the air storage device is determined, and when the pressure of the air storage device is not less than the target value, the corresponding air storage device is used to supply air, and the corresponding control state is entered.

[0248] In other words, when it is determined that the air pressure value in the second air storage device 610 is lower than the preset pressure requirement of the system, the system will determine whether the inflation function of the wheel assembly 740 is being executed;

[0249] If the wheel assembly 740 inflation function is being executed, the system will prioritize executing the wheel assembly 740 inflation function. When it is determined that the control instruction for the wheel assembly 740 inflation function has ended, it will then determine whether the air pressure values ​​in the second air storage device 610 and the first air storage device 510 are both lower than the system preset pressure requirement.

[0250] If the wheel assembly 740 inflation function is not executed, the system directly determines whether the air pressure values ​​in the second air storage device 610 and the first air storage device 510 are both lower than the system preset pressure requirement;

[0251] When it is determined that the air pressure value in the first air storage device 510 is lower than the preset pressure requirement of the system, the system will also determine whether the inflation function of the wheel assembly 740 is being executed.

[0252] In some embodiments, as Figure 10 As shown, the first type of subsystem branch includes a first subsystem branch 50 and a second subsystem branch 60, the second type of subsystem branch includes a third subsystem branch 80, and the air supply system 1 includes a wheel side assembly 740 and the corresponding third subsystem branch 80;

[0253] When it is determined that the air source 30 is supplying air to one of the first and second subsystem branches, the startup instruction corresponding to the execution unit corresponding to the other subsystem branch will not be executed temporarily, including: the air source 30 is supplying air to at least one of the first air storage device 510 and the second air storage device 610, and the startup instruction corresponding to the wheel side assembly 740 will not be executed temporarily.

[0254] In some embodiments, as Figure 10 As shown, the control method of the air supply system 1 includes: when the air supply system 1 includes a wheel side assembly and a corresponding third subsystem branch 80 and receives a start instruction corresponding to the wheel side assembly, determining whether the air source 30 is supplying air to at least one of the first air storage device 510 and the second air storage device 610;

[0255] When it is determined that the air source 30 is supplying air to at least one of the first air storage device 510 and the second air storage device 610 , the execution of the start-up instruction corresponding to the wheel side assembly 740 is suspended.

[0256] In this embodiment, when the air supply system 1 includes a wheel side assembly 740 and a corresponding third subsystem branch 80, and receives a start-up instruction corresponding to the wheel side assembly 740, it is determined whether the air source 30 is supplying air to at least one of the first air storage device 510 and the second air storage device 610. When the air source 30 is not supplying air to at least one of the first air storage device 510 and the second air storage device 610, the air source 30 is controlled to supply air to the third subsystem branch 80 corresponding to the wheel side assembly 740.

[0257] When it is determined that the air source 30 is supplying air to at least one of the first air storage device 510 and the second air storage device 610, the execution of the start-up instruction corresponding to the wheel side assembly 740 is suspended. After the first air storage device 510 or the second air storage device 610 is fully inflated, the execution of the start-up instruction corresponding to the wheel side assembly 740 is continued, and the air source 30 is controlled to supply air to the third subsystem branch 80 corresponding to the wheel side assembly 740.

[0258] After the wheel assembly 740 is inflated, the third subsystem branch 80 corresponding to the wheel assembly 740 is controlled to be disconnected from the central air path 40 to end the inflation of the wheel assembly 740.

[0259] In other words, if it is determined that the inflation control of the first air storage device 510 or the second air storage device 610 is currently being executed, or there is a current inflation demand for the first air storage device 510 or the second air storage device 610, the air source 30 is used first to supply air, and the inflation control of the first air storage device 510 and the second air storage device 610 is performed. After ensuring that there is no inflation demand for the first air storage device 510 or the second air storage device 610, the inflation function of the wheel side assembly 740 is entered.

[0260] In some embodiments, as Figure 11 and Figure 12 As shown, the control method of the gas supply system 1 includes: when it is determined that at least one of the first executing unit 10 and the second executing unit 20 is in an operating state, and the pressure of the first gas storage device 510 is less than a first target value, and the pressure of the second gas storage device 610 is less than a second target value, controlling the gas source 30 to start, controlling the first subsystem branch 50 and the second subsystem branch 60 to be connected to the central gas path 40, so as to inflate the first gas storage device 510 and the second gas storage device 610, and inflate the executing unit in the operating state of the first executing unit 10 and the second executing unit 20;

[0261] When it is determined that the pressure of the first gas storage device 510 is not less than the first target value and the pressure of the second gas storage device 610 is less than the second target value, the gas source 30 is controlled to remain in operation, the first subsystem branch 50 is controlled to be disconnected from the central gas path 40, and the second subsystem branch 60 is controlled to be connected to the central gas path 40, and the first gas storage device 510 is used to supply gas to the first execution unit 10;

[0262] When it is determined that the pressure of the first gas storage device 510 is less than the first target value and the pressure of the second gas storage device 610 is not less than the second target value, the control gas source 30 keeps working, the first subsystem branch 50 is controlled to be connected to the central gas circuit 40, and the second subsystem branch 60 is controlled to be disconnected from the central gas circuit 40, and the first gas storage device 510 is used to supply gas to the second execution unit 20.

[0263] In this embodiment, when the pressure of the first gas storage device 510 is less than the first target value and the pressure of the second gas storage device 610 is less than the second target value, the control gas source 30 is started to control the first subsystem branch 50 and the second subsystem branch 60 to be connected to the central gas path 40 to inflate the first gas storage device 510 and the second gas storage device 610.

[0264] When the pressure of one of the first gas storage device 510 and the second gas storage device 610 meets the target value, the corresponding subsystem branch is controlled to be disconnected from the central gas circuit 40, and the gas storage device is used to supply gas. For example, when it is determined that the pressure of the first gas storage device 510 is not less than the first target value and the pressure of the second gas storage device 610 is less than the second target value, the gas source 30 is controlled to keep working, the first subsystem branch 50 is controlled to be disconnected from the central gas circuit 40, and the second subsystem branch 60 is controlled to be connected to the central gas circuit 40. The first gas storage device 510 is used to supply gas to the first execution unit 10.

[0265] For example, when the pressure of the second gas storage device 610 is not less than the second target value, the second subsystem branch 60 is controlled to be disconnected from the central gas circuit 40, and the second gas storage device 610 is used to supply gas to the second execution unit 20. The first subsystem branch 50 is still connected to the central gas circuit 40, and the gas source 30 is used to supply gas to the first execution unit 10.

[0266] In some embodiments, as Figure 13 As shown, the control method of the air supply system 1 includes: upon receiving a deflation instruction corresponding to at least one air spring assembly 110, controlling the corresponding airbag exhaust valve 114 to open; and / or,

[0267] Upon receiving a charge command corresponding to at least one empty spring assembly 110, the corresponding first sub-control valve 530 is controlled to open, and when the pressure of the first air storage device 510 is not less than a first target value, the first subsystem branch 50 is controlled to be disconnected from the central air circuit 40, and air is supplied to the corresponding empty spring assembly 110 through the first air storage device 510; and / or,

[0268] Upon receiving a charge command corresponding to at least one empty spring assembly 110, the corresponding first sub-control valve 530 is controlled to open, and when the pressure of the first air storage device 510 is less than a first target value, the first subsystem branch 50 is controlled to communicate with the central air path 40, the control air source 30 is activated, and air is supplied to the first air storage device 510 and the corresponding empty spring assembly 110; and / or,

[0269] When a stiffness adjustment instruction corresponding to at least one empty spring assembly 110 is received, the corresponding stiffness control valve 113 is controlled to open.

[0270] In this embodiment, taking the air source 30 including an air pump as an example, when the first execution unit 10 includes an air spring assembly 110, the air spring control function includes an air spring stiffness adjustment function and a vehicle body height adjustment function. When the air supply system 1 performs the air spring height adjustment function, upon receiving a deflation instruction corresponding to at least one air spring assembly 110, the corresponding airbag exhaust valve 114 is controlled to open, and the corresponding airbag exhaust valve 114 is used as an independent exhaust port of the air spring airbag, and the corresponding air spring airbag is controlled to be deflated, thereby reducing the volume of the air spring airbag and lowering the vehicle body.

[0271] When the air supply system 1 performs the air spring height adjustment function, upon receiving an inflation instruction corresponding to at least one air spring assembly 110, the corresponding first sub-control valve 530 is controlled to open, and when the pressure of the first air storage device 510 is not less than the first target value, the first subsystem branch 50 is controlled to be disconnected from the central air circuit 40, and air is supplied to the corresponding air spring assembly 110 through the first air storage device 510, thereby increasing the volume of the air spring airbag and raising the vehicle body.

[0272] When the air supply system 1 performs the air spring stiffness adjustment function, upon receiving a stiffness adjustment instruction corresponding to at least one air spring assembly 110, the corresponding stiffness control valve 113 is controlled to open, connecting the first sub-airbag 111 with the second sub-airbag 112 in the air spring assembly 110, thereby reducing the pressure in the connected airbags and reducing the stiffness of the air spring assembly 110.

[0273] In some embodiments, as Figure 12As shown, the control method of the air supply system 1 includes: upon receiving a deflation instruction corresponding to at least one seat air bag 210, controlling the air bag exhaust valve 640 and the corresponding second sub-control valve 630 to open; and / or

[0274] Upon receiving an inflation command corresponding to at least one seat airbag 210, controlling the corresponding second sub-control valve 630 to open, and when the pressure of the second air storage device 610 is not less than a second target value, controlling the second subsystem branch 60 to be disconnected from the central air circuit 40, and supplying air to the corresponding seat airbag 210 through the second air storage device 610; and / or

[0275] When an inflation command corresponding to at least one seat air bag 210 is received, the corresponding second sub-control valve 630 is controlled to open, and when the pressure of the second air storage device 610 is less than the second target value, the second subsystem branch 60 is controlled to be connected to the central air path 40, the control air source 30 is started, and air is supplied to the second air storage device 610 and the corresponding seat air bag 210.

[0276] In this embodiment, taking the air source 30 including an air pump as an example, when the second execution unit 20 includes a seat air bag 210, the seat air bag 210 massage and adjustment function of the air supply system 1 includes a seat air bag 210 massage function and a seat air bag 210 adjustment function. When the air supply system 1 executes the seat air bag 210 massage function or the seat air bag 210 adjustment function, upon receiving a deflation instruction corresponding to at least one seat air bag 210, the air bag exhaust valve 640 and the corresponding second sub-control valve 630 are controlled to open, and the air bag exhaust valve 640 is used as the main exhaust port. For example, the seat air bag 210 adjustment function can deflate the side air bags and lumbar support air bags of the driver's and passenger seats through the air bag exhaust valve 640, and the seat air bag 210 massage function can deflate the massage air bags of the driver's and passenger seats through the air bag exhaust valve 640.

[0277] When the air supply system 1 performs the seat airbag 210 massage function or the seat airbag 210 adjustment function, upon receiving an inflation instruction corresponding to at least one seat airbag 210 , the corresponding second sub-control valve 630 is controlled to open to supply air to the corresponding seat airbag 210 .

[0278] When the pressure of the second air storage device 610 is not less than the second target value, the second subsystem branch 60 is controlled to be disconnected from the central air circuit 40, and the corresponding seat airbag 210 is supplied with air through the second air storage device 610. For example, the adjustment function of the seat airbag 210 can use the second air storage device 610 to supply air, and the side airbags and lumbar support airbags of the driver and passenger are inflated respectively through the corresponding second sub-control valve 630. The massage function of the seat airbag 210 can use the second air storage device 610 to inflate the massage airbags of the driver and passenger.

[0279] When the pressure of the second air storage device 610 is less than the second target value, the second subsystem branch 60 is controlled to be connected to the central air path 40, the air source 30 is controlled to start, and air is supplied to the second air storage device 610 and the corresponding seat airbag 210. For example, the adjustment function of the seat airbag 210 can use the air source 30 to supply air to inflate the second air storage device 610 and the side airbags and lumbar support airbags for the driver and passenger seats. The massage function of the seat airbag 210 can use the air source 30 to supply air to inflate the second air storage device 610 and the massage airbags for the driver and passenger seats.
