Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a wing system and a vehicle having the wing system. Background Art

[0002] In related technologies, the wing system uses a controller to control the compressed air from the air compressor to enter the air tank, which is then controlled by a solenoid valve to control the air to enter the wing airbag, and finally the solenoid valve controls the air to be discharged to the atmosphere.

[0040] Reference below Figure 1-Figure 5 A side wing system 100 according to an embodiment of the present invention is described. The side wing system 100 is constructed as a closed system and does not exhaust directly into the vehicle interior, which helps reduce exhaust odor inside the vehicle. The water content of the gas in the side wing inflation circuit 11 is constant, and the possibility of water separation is extremely small, which helps reduce the risk of water accumulation and ice formation. In addition, the side wing airbag 13 and the air spring 14 share the same air compressor 12, which helps reduce the operating cost of the air compressor 12.

[0041] like Figure 1-Figure 5 As shown, a wing system 100 according to an embodiment of the present invention includes a wing inflation circuit 11 and an air spring 14 .

[0042] An air compressor 12 and a side wing airbag 13 are provided in the side wing inflation circuit 11. The side wing airbag 13 can be used to provide safe and comfortable support and protection for the occupants to provide better riding comfort and safety. The side wing airbag 13 can adjust the softness, hardness and wrapping of the seat by inflating and deflating air, thereby providing a better riding experience.

[0043] The air compressor 12 and the wing airbags 13 are arranged in series, and the wing inflation circuit 11 is connected to an air intake and exhaust structure. That is, when the air compressor 12 is in operation, it can supply air from the air intake and exhaust structure into the wing inflation circuit 11, thereby delivering the air to the wing airbags 13 through the wing inflation circuit 11 to inflate the wing airbags 13, thereby increasing the volume or supporting strength of the wing airbags 13. Alternatively, the air in the wing airbags 13 can be released through the wing inflation circuit 11 to deflate the wing airbags 13, thereby reducing the volume or supporting strength of the wing airbags 13. The air entering the wing inflation circuit 11 can form a closed circulation within the wing inflation circuit 11, thus forming the wing system 100 as a closed system. Furthermore, the air entering the wing inflation circuit 11 is compressed and dried by the air compressor 12, making it less susceptible to water accumulation and ice formation, thereby ensuring the structural stability and safety of the wing system 100.

[0044] Among them, the side wing inflation circuit 11 can take in air from outside the vehicle through the air intake and exhaust structure, and can also exhaust toward the outside of the vehicle. That is, the side wing airbag 13 will not exhaust directly into the cockpit, making it less likely to produce odor, and can also reduce the odor requirements of the air path parts, thereby reducing costs.

[0045] The air spring 14 is connected to the wing inflation circuit 11, allowing the air spring 14 to be selectively connected to the wing inflation circuit 11, allowing gas introduced into the wing inflation circuit 11 via the air compressor 12 to enter the air spring 14. Furthermore, the gas in the air spring 14 can also enter the wing inflation circuit 11. This allows the wing airbags 13 and the air spring 14 to share the air compressor 12 and the wing inflation circuit 11, thereby reducing installation costs. In other words, the air spring 14 and the wing airbag 13 do not need to be equipped with separate air compressors 12. Sharing the air compressor 12 not only reduces costs but also allows for a lighter vehicle design. Furthermore, the air suspension air compressor 12 has a higher atmospheric efficiency than a conventional wing air compressor 12, thereby improving the gas efficiency of the wing airbags 13.

[0046] According to the side wing system 100 of the embodiment of the present invention, the side wing system 100 is constructed as a closed system and does not exhaust directly into the vehicle, which helps reduce exhaust odor in the vehicle. The water content of the gas in the side wing inflation circuit 11 is constant, and the possibility of water separation is extremely small, which helps reduce the risk of water accumulation and ice formation. The side wing airbag 13 and air spring 14 share the same air compressor 12 and intake and exhaust structure, which not only helps reduce the operating cost of the air compressor 12, but also helps achieve a lightweight design for the vehicle.

[0047] In some embodiments, the wing inflation circuit 11 is further provided with an empty spring air tank 15, which is adapted to be selectively connected to the wing air bag 13, the air spring 14 or the air intake and exhaust structure. Figure 1-Figure 5 As shown, the empty spring air tank 15, the side wing air bag 13 and the air compressor 12 are all connected in series in the side wing inflation circuit 11, and the empty spring air tank 15 can be selectively connected to the air compressor 12 and the intake and exhaust structure through the side wing inflation circuit 11, and can also be selectively connected to the side wing air bag 13, and can also be selectively connected to the air spring 14.

[0048] Thus, the communication relationship between the various structural components in the wing inflation circuit 11 can be switched to switch the working mode of the wing system 100. Figure 2 As shown, the air intake and exhaust structure and the air spring 14 can be connected to the side wing inflation circuit 11, and the air compressor 12 drives the air intake toward the air spring air tank 15 and the air spring 14 to realize the inflation process of the inflation spring, or as shown in FIG. Figure 3 As shown, the air compressor 12 is not working, and the gas in the air spring 14 and the air spring air tank 15 can be discharged from the air intake and exhaust structure to achieve the exhaust process of the air spring 14. And, as Figure 4 As shown, the empty spring air tank 15 can be connected to the side wing air bag 13 through the side wing inflation circuit 11, so that the empty spring air tank 15 is inflated toward the side wing air bag 13, or, as shown in FIG. Figure 5 As shown, the side wing airbags 13 can be connected to the empty spring air tank 15 through the side wing inflation circuit 11 and the air is pumped from the side wing airbags 13 toward the empty spring air tank 15 through the air compressor 12 to achieve the exhaust function of the side wing airbags 13.

[0049] In this way, by setting an empty spring air tank 15 in the side wing inflation circuit 11, it can be inflated at the same time as the air spring 14, and the empty spring air tank 15 can also inflate toward the side wing air bag 13, thereby realizing the structural integration of the two functions of the side wing air bag 13 and the air spring 14, reducing the setting of the air compressor 12, and helping to reduce the setting cost.

[0050] In some embodiments, the wing inflation circuit 11 further includes a wing air tank 16 connected in series between the empty spring air tank 15 and the wing airbag 13. This means that both the empty spring air tank 15 and the wing air tank 16 can be used to store air. Thus, during inflation of the wing airbag 13, the empty spring air tank 15 and the wing air tank 16 can sequentially supply air to the wing airbag 13.

[0051] In other words, during the inflation of the wing airbags 13, the gas in the empty spring air tank 15 can be introduced into the wing air tank 16, and the air pressure in the wing air tank 16 can be controlled to be lower than the air pressure in the empty spring air tank 15. The wing air tank 16 is then connected to the wing airbags 13, allowing the gas in the wing air tank 16 to enter the wing airbags 13. This prevents the gas pressure directly entering the wing airbags 13 from being too high, that is, it prevents the high pressure in the empty spring air tank 15 from directly acting on the wing airbags 13 and other structures between the empty spring air tank 15 and the wing airbags 13, causing damage to system components, thereby improving system safety. Similarly, the gas in the wing airbags 13 can also enter the empty spring air tank 15 through the air compressor 12, realizing gas flow from the wing airbags 13 to the empty spring air tank 15.

[0052] Among them, the gas in the side wing system 100 can flow between the empty spring air tank 15, the side wing air tank 16 and the side wing air bag 13 to realize the internal circulation of the air flow in the side wing system 100. The gas is stored in the system for a long time, the water content in the system is constant, the possibility of water separation is extremely small, and it is not easy to cause water accumulation and ice.

[0053] In some embodiments, as Figure 1-Figure 5 As shown, a first on-off valve 21 is also provided in the wing inflation circuit 11. The first on-off valve 21 is connected in series between the wing air tank 16 and the empty spring air tank 15. The first on-off valve 21 can control the flow path between the wing air tank 16 and the empty spring air tank 15, and flexibly switch the connectivity state of this part of the flow path.

[0054] Among them, the first on-off valve 21 can be constructed as an electromagnetic valve, or it can also be a valve body of other control forms, that is, when the side wing airbag 13 is inflated, the first on-off valve 21 can be actively opened to connect the empty spring air tank 15 with the side wing air tank 16, so that the gas in the empty spring air tank 15 can enter the side wing air tank 16 through the first on-off valve 21, and after the pressure in the side wing air tank 16 reaches a certain height, the first on-off valve 21 is closed, and then enters the side wing airbag 13 through the side wing air tank 16.

[0055] Therefore, by providing the first on-off valve 21, not only can the empty spring air tank 15 be guaranteed to be able to normally inflate the wing air tank 16, but when the first on-off valve 21 is closed, the gas in the empty spring air tank 15 can be prevented from automatically entering the wing air tank 16, thereby ensuring a stable air pressure in the wing airbag 13. At the same time, the gas in the empty spring air tank 15 is prevented from automatically leaking, thereby ensuring the efficiency of the air compressor 12 in inflating the empty spring air tank 15.

[0056] In some embodiments, the wing inflation circuit 11 is further provided with a pressure-limiting valve 24, which is connected in series between the wing air reservoir 16 and the wing airbag 13. The gas pressure in the wing air reservoir 16 flows through the pressure-limiting valve 24 to the wing airbag 13. In other words, the pressure-limiting valve 24 controls the air pressure within a constant range, thereby achieving stable pressure control.

[0057] Therefore, by providing the pressure-limiting valve 24 , the gas pressure entering the side airbag 13 can be effectively controlled, thereby preventing excessive gas pressure from acting on the side airbag 13 , preventing the excessive gas pressure in the side airbag 13 from causing pressure shock to the occupants, and improving occupant safety.

[0058] In some embodiments, the wing air storage tank 16 is provided with a first pressure detection component 31 , that is, the air pressure in the wing air storage tank 16 can be detected by the first pressure detection component 31 , thereby obtaining the pressure in the wing air storage tank 16 .

[0059] The first pressure detection member 31 may be configured as a pressure sensor, which may be installed on the wing air storage tank 16 to directly detect the pressure in the wing air storage tank 16 to ensure accuracy and reliability of pressure detection.

[0060] Furthermore, when the side wing air tank 16 is inflated through the empty spring air tank 15, the first on-off valve 21 can be opened to detect the pressure of the side wing air tank 16 through the first pressure detection component 31. After the first pressure detection component 31 detects that the pressure in the side wing air tank 16 reaches a certain pressure value, the first on-off valve 21 can be controlled to close, so that the empty spring air tank 15 stops inflating the side wing air tank 16, thereby controlling the pressure in the side wing air outlet pipe within the required range, thereby preventing the air pressure in the side wing air tank 16 from being too high and impacting the side wing airbag 13.

[0061] In some embodiments, the wing inflation circuit 11 is connected to the air spring 14 through an air spring branch 41, and the air spring branch 41 is parallel between the air compressor 12 and the air spring air tank 15, that is, one end of the air spring branch 41 is connected between the air compressor 12 and the air spring air tank 15, and the other end of the air spring branch 41 is connected to the air spring 14.

[0062] In this way, Figure 2As shown, during the inflation process of the air spring 14, the air compressor 12 is working, and the air intake and exhaust structure takes in air. The airflow at the air compressor 12 can flow in two ways, one way flows to the air spring air tank 15, and the other way enters the air spring branch 41, and enters the air spring 14 through the air spring branch 41 to achieve the inflation of the air spring 14 and the air spring air tank 15. Among them, under most working conditions, the air spring 14 and the air spring air tank 15 are inflated separately, and only in very rare cases are they inflated at the same time. And when the air spring 14 is deflated, the air spring 14 and the air spring air tank 15 can also be deflated separately, or in very rare cases, they can be deflated at the same time. In this way, the air spring 14 and the air spring air tank 15 can share the same set of structures for inflation and deflation.

[0063] Specifically, if Figure 2 and Figure 3 As shown, the position of the air intake and exhaust structure can be set on the side of the air compressor 12 away from the air spring branch 41 and the air spring air tank 15, so that the gas entering the air spring 14 and the air spring air tank 15 and the exhausted gas both pass through the air compressor 12, which is conducive to achieving the effect of drying the gas through the air compressor 12.

[0064] In some embodiments, at least one second on-off valve 22 is provided in the air spring branch 41. That is, the second on-off valve 22 can actively control the on-off of the air spring branch 41 to flexibly switch the air flow state of the air spring 14. The second on-off valve 22 can be provided as one, or as two or more.

[0065] Among them, the second on-off valve 22 can be constructed as a solenoid valve, or it can also be a valve body of other control forms, that is, when the air spring 14 is inflated or deflated, the second on-off valve 22 can be actively opened to connect the air spring 14 with the intake and exhaust structure, so that the external airflow can enter the side wing inflation circuit 11 from the intake and exhaust structure to enter the air spring 14 from the second on-off valve 22. At this time, the part entering the air spring air tank 15 can be closed to prevent the gas from entering the air spring air tank 15, thereby realizing the inflation process of the air spring 14, or the gas in the air spring 14 can enter the side wing inflation circuit 11 through the second on-off valve 22 and be discharged from the intake and exhaust structure to realize the exhaust of the air spring 14.

[0066] Therefore, by setting the second on-off valve 22, not only can the air spring 14 be inflated or deflated normally, but also when the second on-off valve 22 is closed, the gas in the air spring 14 can be prevented from automatically entering the wing inflation circuit 11, thereby ensuring that the air pressure in the air spring 14 is stable.

[0067] In some embodiments, a third on-off valve 23 is also provided in the wing inflation circuit 11. The third on-off valve 23 is connected in series between the air spring air tank 15 and the air compressor 12, and is distributed in parallel with the air spring branch 41. That is, the wing inflation circuit 11 can be selectively turned on and off through the third on-off valve 23, that is, the third on-off valve 23 can switch the connection state between the air spring air tank 15 and the air compressor 12.

[0068] The third on-off valve 23 can also be constructed as a solenoid valve, or can also be a valve body of other control forms, that is, when the air spring air tank 15 is inflated or deflated, the third on-off valve 23 can be actively opened to connect the air spring air tank 15 with the intake and exhaust structure, so that the external airflow can enter the wing inflation circuit 11 from the intake and exhaust structure to enter the air spring air tank 15 from the third on-off valve 23, thereby realizing the inflation process of the air spring air tank 15, or the gas in the air spring air tank 15 can enter the air compressor 12 through the third on-off valve 23 and be discharged from the intake and exhaust structure, thereby realizing the exhaust of the air spring air tank 15.

[0069] Therefore, by providing the third on-off valve 23, not only can the normal inflation or deflation of the air spring reservoir 15 be ensured, but when the third on-off valve 23 is closed, the gas in the air spring reservoir 15 can be prevented from automatically entering and being discharged from the air intake and exhaust structure, thereby ensuring the stability of the air pressure in the air spring reservoir 15. At this time, the second on-off valve 22 can be opened to perform the independent inflation and deflation process of the air spring 14.

[0070] In some embodiments, a second pressure detection component 32 is provided at the connection point between the air spring branch 41 and the wing inflation circuit 11, that is, the second pressure detection component 32 can be used to detect the inflation and exhaust pressure of the air spring 14 and the air spring air tank 15, so as to actively control the corresponding control valve through the detection value of the second pressure detection component 32.

[0071] Among them, the second pressure detection component 32 can be constructed as a pressure sensor, which can be installed in the side wing inflation circuit 11 to detect the inflation and exhaust pressure of the air spring 14 and the air spring air tank 15 to ensure the accuracy and reliability of the pressure detection.

[0072] In addition, when the air spring 14 and the air spring air tank 15 are inflated or exhausted through the air compressor 12 and the air intake and exhaust structure, the second on-off valve 22 and the third on-off valve 23 can be opened to detect the inflation and exhaust pressure through the second pressure detection component 32. After the second pressure detection component 32 detects that the inflation and exhaust pressure reaches a certain pressure value, the second on-off valve 22 and the third on-off valve 23 can be controlled to close, so that the air spring 14 and the air spring air tank 15 stop inflating or exhausting, thereby realizing accurate control of inflation and exhaust.

[0073] In some embodiments, an air circuit switching valve 33 is also provided in the side wing inflation circuit 11, and the air circuit switching valve 33 includes a first valve port 331, a second valve port 332 and a third valve port 333. The first valve port 331 and the second valve port 332 are both connected to the side wing inflation circuit 11, and the third valve port 333 is connected to the intake and exhaust structure, and the first valve port 331 is constructed to selectively connect with the second valve port 332 or the third valve port 333, so that the intake and exhaust structure is selectively connected to the side wing inflation circuit 11 through the air circuit switching valve 33.

[0074] Specifically, if Figure 2 As shown, the left side of the air path switching valve 33 is provided with a first valve port 331, and the right side of the air path switching valve 33 is provided with a second valve port 332 and a third valve port 333. The third valve port 333 is located below the second valve port 332. At the same time, an air intake and exhaust structure is provided below the right side of the air path switching valve 33. The first valve port 331 can be connected to the second valve port 332 on the right side and disconnected from the third valve port 333, so that the air path switching valve 33 can fully connect the wing inflation circuit 11. At this time, Figure 5 As shown, the gas in the side airbag 13 can enter the air path switching valve 33 from the second valve port 332, and enter the air compressor 12 and the air spring air tank 15 from the first valve port 331, or, as shown in FIG. Figure 2 and Figure 4 As shown, the first valve port 331 can be disconnected from the second valve port 332 on the right and connected to the third valve port 333, so that the air circuit switching valve 33 connects the side wing inflation circuit 11 with the intake and exhaust structure. In this way, the gas at the intake and exhaust structure can enter the side wing inflation circuit 11 from the air circuit switching valve 33 to inflate the air spring 14 and the empty spring air tank 15, or the gas in the air spring 14 and the empty spring air tank 15 can also be discharged from the side wing inflation circuit 11 by the third valve port 333 of the air circuit switching valve 33.

[0075] Therefore, the provision of the air path switching valve 33 can achieve selective communication between the side flap inflation circuit 11 and the intake and exhaust structure, making it easier to achieve inflation and exhaust in the side flap inflation circuit 11.

[0076] In some embodiments, the intake and exhaust structure comprises an intake and exhaust branch 42 and an air filter 43. The intake and exhaust branch 42 is connected to the side wing inflation circuit 11. One end of the intake and exhaust branch 42 communicates with the third valve port 333, while the other end of the intake and exhaust branch 42 can be connected to the atmosphere, such as outside the vehicle body. This allows air to be injected into the side wing inflation circuit 11 through the intake and exhaust branch 42, or for air in the side wing inflation circuit to be discharged through the intake and exhaust branch 42.

[0077] Among them, the air filter 43 is arranged in the intake and exhaust branch 42, that is, the air filter 43 can filter the gas in the intake and exhaust branch 42 to prevent dirt from entering the side wing inflation circuit 11 along with the gas, ensuring that the air spring 14 and the side wing airbag 13 are used cleanly and safely.

[0078] Furthermore, the other end of the intake and exhaust branch 42 is connected to the exterior of the vehicle body, allowing the gas in the wing system 100 to be discharged outside the vehicle body. In other words, the wing airbags 13 of the wing system 100 of the present invention do not need to be exhausted into the cockpit, making them less likely to generate odor and also reducing the odor requirements of the air path components, thereby reducing costs.

[0079] In some embodiments, the side wing inflation circuit 11 includes at least two side wing branches 44 distributed in parallel, that is, the side wing branches 44 can be set to two, three, four or more, and the number of side wing branches 44 is not limited to this, wherein at least two side wing branches 44 distributed in parallel can be respectively connected in series in the side wing inflation circuit 11.

[0080] Each wing branch 44 is provided with a wing airbag 13 , that is, the number of the wing airbags 13 corresponds to the number of the wing branches 44 , so as to increase the number of the wing airbags 13 .

[0081] Specifically, if Figure 1-Figure 5 As shown, two wing branches 44 are provided, arranged in parallel, and each wing branch 44 is provided with a wing airbag 13. One of the two wing airbags 13 can be provided on the driver's seat, and the other on the passenger seat. That is, the wing airbags 13 on both seats can be inflated and deflated via the same wing inflation circuit 11, which helps reduce the number of wing inflation circuits 11 and lowers installation costs.

[0082] As well as Figure 1-Figure 5 As shown, a three-way valve 25 may be provided at the connection of the two side wing branches 44 , so that the two side wing branches 44 are provided in parallel in the side wing inflation circuit 11 through the three-way valve 25 .

[0083] In some embodiments, the wing system 100 also includes a main controller 5, which is used to control the connectivity status of the air spring 14, the air intake and exhaust structure, and the wing inflation circuit 11, that is, the main controller 5 can actively control the various valve structures in the wing inflation circuit 11 to achieve switching of the connectivity status of the wing inflation circuit 11.

[0084] Specifically, the air compressor 12, the air circuit switching valve 33, the first on-off valve 21, the second on-off valve 22 and the third on-off valve 23 in the wing system 100 are all electrically connected to the main controller 5. At the same time, the first pressure detection component 31 and the second pressure detection component 32 are also electrically connected to the main controller 5, so that the main controller 5 can actively control the air compressor 12, the air circuit switching valve 33, the first on-off valve 21, the second on-off valve 22 and the third on-off valve 23 based on the detection results of the first pressure detection component 31 and the second pressure detection component 32, thereby realizing the collaborative cooperation of multiple valve body structures, which is conducive to meeting the control requirements under different charging and exhaust modes.

[0085] Thus, multiple modes of control and switching can be achieved, as follows:

[0086] like Figure 2 The diagram shows the air circuit for charging the air spring 14. The main controller 5 switches the air circuit switching valve 33 to the air filter 43, switching the air circuit switching valve 33 to external circulation. The air compressor 12 is then started, and the second on-off valve 22 or the third on-off valve 23 is opened as needed to inflate the air spring 14 or the air spring tank 15. The inflation pressure is controlled by the second pressure sensor 32. Because the air compressor 12 includes a built-in drying unit, the gas charged into the air spring 14 or the air spring tank 15 is dried and low in moisture. This process enables functions such as air suspension lifting and inflation of the air spring tank 15 without affecting the original functions of the air suspension.

[0087] like Figure 3 The figure shows the exhaust path for air spring 14. Main controller 5 switches air path switching valve 33 to the direction of air filter 43, switching air path switching valve 33 to external circulation. It then opens second on-off valve 22 or third on-off valve 23 as needed to exhaust air from air spring 14 or air spring air tank 15. The exhaust endpoint is controlled by second pressure detector 32 or the vehicle height sensor, and the air is ultimately discharged to the atmosphere through air filter 43. This process enables functions such as lowering the air suspension and exhausting the air tank, without affecting the original functions of the air suspension.

[0088] like Figure 4 The diagram shows the inflation circuit for the side wing system 100. The main controller 5 controls the opening of the first on-off valve 21, allowing the air spring reservoir 15 to inflate the side wing reservoir 16. The process stops when the required pressure is reached. The gas in the side wing reservoir 16 is maintained at a constant pressure by the pressure-limiting valve 24. The gas then passes through the three-way valve 25 to the side wing airbags 13 for the driver and passenger seats. Based on the vehicle's steering and acceleration signals, the main controller 5 controls the actuators within the seats to inflate the side wing airbags 13, allowing the side wing to support the user's tilt. The gas used in this process is dried by the air compressor 12, making it less susceptible to water accumulation and ice formation.

[0089] As well as Figure 5 The figure shows the exhaust gas circuit diagram of the wing system 100. When the wing is triggered, the main controller 5 controls the gas circuit switching valve 33 to switch to the closed system, starts the air compressor 12, opens the third on-off valve 23, controls the actuator inside the seat to exhaust the wing airbag 13, and transfers the gas from the wing airbag 13 to the air spring tank 15. This process dries the used gas again, making it less likely to accumulate water and ice. Figure 4 and Figure 5 Combined into a complete side wing closed system.

[0090] It should be noted that the solid lines in the figure are gas connections, and the dotted lines are circuit connections.

[0091] The present invention also provides a vehicle.

[0092] A vehicle according to an embodiment of the present invention includes a wing system 100 according to any of the above-described embodiments. The wing system 100 is a closed system with almost no gas exchange, making it less likely to cause water accumulation and ice formation, and making the system more reliable. The air suspension's air compressor 12 can be utilized to its maximum potential, combining the air suspension system and the wing system 100 to share a common air compressor 12, thereby reducing costs and facilitating vehicle lightweighting. Furthermore, the air suspension's air compressor 12 is more powerful and quicker to inflate than the wing system 100's air compressor 12. Furthermore, the air spring air tank 15 (large tank) is used to inflate the wing's air tank 16 (small tank), instantly filling the small tank and enabling faster wing triggering.

[0093] In addition, the wing system 100 of the present invention is a closed system. The gas discharged from the wing airbag 13 is recollected in the empty spring air tank 15, that is, the gas is not discharged into the cabin, which can reduce the odor requirements of the air path parts and thus reduce costs. The wing system 100 integrates the air suspension controller and the seat wing controller into one, realizing that one controller controls two systems, making the system control structure simpler, reducing conflicts during the operation of the two systems, and making the overall system more stable.
