The active tire pressure control system is a device that can be used to solve the problem of automatic air pressure adjustment of automobile tires in a variety of different scenarios.

[0050] Embodiments of the present application are described in detail below, and 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 intended to be used to explain the present application, and should not be construed as limiting the present application.

[0051] The vehicle tire pressure active regulation system, vehicle, and control method of the vehicle tire pressure active regulation system proposed in the embodiments of the present application are described below with reference to the accompanying drawings.

[0052] In related technologies, the vehicle is equipped with an active tire pressure control system to meet the needs of automatic air pressure adjustment of automobile tires in various scenarios. The active tire pressure control system introduces compressed gas into the integrated valve through the vehicle-mounted air pump, and uses the combined action of the integrated valve and the safety valve corresponding to the tire to achieve a series of actions such as inflation, deflation, pressure maintenance, and pressure measurement of the corresponding tire.

[0053] However, although the above technical solution can realize the tire pressure adjustment and control of the vehicle, the air pump used in the active tire pressure control device is limited by factors such as cost, pressure, NVH performance, and vehicle energy efficiency. Vehicle manufacturers will not use a large-flow air pump, which greatly reduces the inflation rate and reduces the user experience.

[0054] In order to solve the above-mentioned technical problems, the present application proposes a vehicle tire pressure active adjustment system. By setting a first air source and a second air source, the first air source, or the second air source, or both air sources can be used as air source devices in the process of adjusting the tire pressure. The first air source and the second air source form a parallel relationship through the corresponding structural air path. When adjusting the tire pressure, the two air sources can be used independently and complement each other, thereby ensuring the air adjustment rate and NVH performance and improving the user experience.

[0055] Figure 1 It is a block diagram of a vehicle tire pressure active adjustment system according to an embodiment of the present application.

[0056] like Figure 1As shown, the vehicle tire pressure active regulation system of the present application includes: a first air source 10, a second air source 20, an air valve module 30 and a controller 50. The first air source 10 and the second air source 20 are respectively connected to each tire 40 of the vehicle through the air valve module 30. The controller 50 is used to control the air valve module 30 so that at least one of the first air source 10 and the second air source 20 works to regulate the tire pressure of the corresponding tire.

[0057] Specifically, the air outlets of the first air source 10 and the second air source 20 are respectively connected to the two inlets of the air valve module 30 through the air path, and are connected to each tire 40 of the vehicle through the air valve module 30. The first air source 10 and the second air source 20 are connected through the air path to form a parallel relationship. When the tire pressure of the corresponding tire is adjusted, the first air source 10 and the second air source 20 can both be used as air source devices, wherein the tire pressure adjustment includes actions such as inflation, deflation, and pressure maintenance. For example, when the vehicle tire pressure active adjustment system inflates the tire 40, the controller 50 can control the opening and closing of the air valve module 30 to connect the air path between the first air source 10 and the corresponding tire 40, and close the air path between the second air source 20 and the corresponding tire 40, so as to inflate the corresponding tire through the first air source 10; or, close the air path between the first air source 10 and the corresponding tire 40, and connect the air path between the second air source 20 and the corresponding tire 40, so as to inflate the corresponding tire through the second air source 20; or, connect the air path between the first air source 10 and the corresponding tire 40, and the air path between the second air source 20 and the corresponding tire 40. At this time, the corresponding tire 40 is inflated through the first air source 10 and the second air source 20. The controller 50 can control the air valve module 30 according to actual conditions, so that the first air source 10 and the second air source 20 can be used independently and complement each other, thereby effectively ensuring the inflation rate.

[0058] Therefore, when the vehicle tire pressure active adjustment system adjusts the tire 40, the first air source 10 and the second air source 20 can both be used as air source devices, and the two are in a parallel relationship. Then, when the system adjusts the tire pressure of the tire 40, the controller 50 controls the air valve module 30 so that the two can be used independently and complement each other, thereby effectively ensuring the tire pressure adjustment rate.

[0059] Furthermore, if Figure 2As shown, the air valve module 30 may include an integrated valve 31 and a safety valve 32 corresponding to the tire 40. In this embodiment, the vehicle tire pressure active adjustment system is composed of the first air source 10, the second air source 20, the integrated valve 31, the safety valve 32, the controller 50, the tire pressure monitoring sensor 60 and other subsystems and corresponding system structure air circuits, wherein the integrated valve 31 is an electric control valve and the safety valve 32 is an air control valve. The controller 50 collects and analyzes various signal data and performs comprehensive control on each subsystem to achieve tire pressure adjustment of the tire 40. Among them, the signal data may include gear information, vehicle speed information, temperature information, and tire pressure signals obtained by the tire pressure monitoring control module 70 that establishes communication with the tire pressure monitoring sensor 60, etc., which are not limited here. In addition, the controller 50 is also connected to the vehicle instrument multimedia central control screen 80. On the one hand, the data signal received or processed by the controller 50 can be displayed through the vehicle instrument multimedia central control screen 80. On the other hand, the controller 50 can receive the control instructions triggered by the vehicle instrument multimedia central control screen 80, thereby performing corresponding voltage regulation actions according to the control instructions.

[0060] It should be noted that the first gas source 10 and the second gas source 20 may be gas sources of the same type, for example, both the first gas source 10 and the second gas source 20 are gas tanks, or they may be gas sources of different types, for example, one of them is an air pump and the other is a gas tank, which may be set according to actual conditions.

[0061] Combination Figure 3 As shown, in one embodiment of the present application, the second air source 20 includes an air tank 21, wherein the controller 50 is also used to obtain the pressure value of the air tank 21 when inflating the corresponding tire, and when the pressure value of the air tank 21 is greater than or equal to the first preset pressure value P1, control the air valve module 30 to inflate the corresponding tire through the air tank 21.

[0062] In this embodiment, the compressed gas storage tank 21 is used as a high-pressure gas source. The capacity of the gas storage tank 21 can be flexibly adjusted according to the surplus space in the vehicle, and is mainly used to quickly inflate the tire 40.

[0063] When the controller 50 performs the inflation operation on the corresponding tire according to the received tire inflation instruction, it first obtains the pressure value of the air tank 21. When it is determined that the pressure value of the air tank 21 is greater than or equal to the first preset pressure value P1, it is determined that the gas pressure stored in the air tank 21 reaches the specified pressure value preset by the system, and the pressure stored in the air tank 21 is sufficient. At this time, the vehicle tire pressure active adjustment system defaults to using the air tank 21 to inflate the tire 40. The controller 50 controls the air valve module 30 to connect the air path between the corresponding tire 40 and the air tank 21, and ensures that the air path between the corresponding tire and the first air source 10 is cut off, so that the high-pressure gas in the air tank 21 passes through the air valve module 30 to inflate the corresponding tire.

[0064] It should be noted that the first gas source 10 may also be a gas storage container. For example, the second gas source 10 includes gas storage tanks of different volumes. Figure 2 The air pump 11 shown, when the first air source 10 includes the air pump 11, and the air pump 11 is used as the air source, in addition to the above-mentioned technical solution of ensuring that the air path between the corresponding tire and the first air source 10 is cut off by controlling the valve to avoid the first air source 10 inflating the corresponding tire, the controller 50 can also control the air pump 11 in the first air source 10 not to work. At this time, the air pump 11 does not output compressed gas. Even if the control valve is not set at the air outlet of the air pump 11, it can be ensured that the air pump 11 does not inflate the corresponding tire 40.

[0065] In one embodiment of the present application, Figure 3 As shown, the first air source 10 includes an air pump 11, and the air valve module 30 includes: an air valve 33, the first end of the air valve 33 is connected to the air tank 21; a control valve 34, and the second end of the air valve 33 is connected to the corresponding tire 40 via the control valve 34; wherein, the outlet of the air pump 11 is connected between the second end of the air valve 33 and the control valve 34.

[0066] The air pump 11 is a conventional air source, which can provide compressed air for the entire vehicle tire pressure active regulation system and can be used for conventional inflation of the tire 40 .

[0067] Specifically, both the first end and the second end of the inflation valve 33 can be inlet, and the control valve 34 is set in one-to-one correspondence with the tire 40. When the controller 50 receives the inflation instruction for the corresponding tire, if it is determined that the corresponding tire is inflated through the air tank 21, the inflation pump 11 is controlled not to work, and the inflation valve 33 and the control valve 34 corresponding to the corresponding tire are controlled to open, so that the air path between the air tank 21 and the corresponding tire is connected, and the tire is inflated through the air tank 21. If it is determined that the corresponding tire is inflated through the inflation pump 11, the inflation pump 11 is controlled to work and the control valve 43 corresponding to the corresponding tire is controlled to open, so that the air path between the inflation pump 11 and the corresponding tire is connected, so that the tire is inflated by the compressed gas provided by the inflation pump 11. At the same time, the inflation valve 33 should be kept closed to prevent the compressed gas discharged by the inflation pump 11 from entering the air tank 21 through the inflation valve 33, and the air tank 21 is closed at the same time to prevent the gas in the air tank 21 from flowing out.

[0068] In addition, the air pump 11 can not only adjust the tire pressure of the tire 40, but also inflate the air tank 21. Specifically, the control valve 34 can be controlled to be closed, the inflation valve 33 can be controlled to be opened, and the air pump 11 can be controlled to work. At this time, the air path between the air pump 11 and the air tank 21 is connected, and the compressed gas provided by the air pump 11 enters the liquid tank 21 through the inflation valve 33 to perform air replenishment of the liquid tank 21. Figure 4 As shown, the number of tires 40 of the vehicle is four, namely, the left front wheel tire 41, the right front wheel tire 42, the left rear wheel tire 43, and the right rear wheel tire 44. The first safety valve 321, the second safety valve 322, the third safety valve 323, and the fourth safety valve 324 in the safety valve 32 are respectively arranged on the four tires 40, and the control valve 34 arranged corresponding to the tire 40 includes the first control valve 312, the second control valve 313, the third control valve 314, and the fourth control valve 315. In this embodiment, in addition to the safety valve 32, the inflation valve 33, and the control valve 34, the air valve module 30 is also provided with a quick release valve 316 and a deflation valve 317, wherein the inflation valve 33, the control valve 34, the quick release valve 316, and the deflation valve 317 are integrated in the integrated valve 31, and the controller 50 controls the integrated valve 31 and the inflation pump 11 to achieve the corresponding pressure regulation action.

[0069] Furthermore, the safety valve 32 is arranged on the rim of the wheel, and the two ends of the safety valve 32 are respectively connected to the tire 40 and the rotating sealed air chamber arranged on the hub unit through an air pipe. The rotating sealed air chamber is connected to the integrated valve 31 through the air pipe to form a complete air pressure control circuit. The four tires 40 each branch out a single-tube air path from the integrated valve 31, which can inflate, deflate and maintain the pressure of each tire 40. The air pressure sensor in the integrated valve 31 can also measure the air pressure value of each tire 40. Specifically, the outlet of the air storage tank 21 is connected to the first end of the inflation valve 33, and after the second end of the inflation valve 33 is connected to the outlet of the inflation pump 11, it is connected to the left front wheel tire 41 through the first control valve 312, the left front wheel tire rotating sealing device 411, and the first safety valve 321; it is connected to the right front wheel tire 42 through the second control valve 313, the right front wheel tire rotating sealing device 421, and the second safety valve 322; it is connected to the left rear wheel tire 43 through the third control valve 314, the left rear wheel tire rotating sealing device 431, and the third safety valve 323; it is connected to the right rear wheel tire 44 through the fourth control valve 315, the right rear wheel tire rotating sealing device 441, and the fourth safety valve 324.

[0070] The air pump 11, the integrated valve 31 and the controller 50 are connected through a circuit, and the controller 50 directly controls the air pump 11 and each valve in the integrated valve 31, thereby controlling the working state of the system gas source and the system structure gas path. The opening and closing of the air tank 21 can be directly controlled by the inflation valve 33 in the integrated valve 31. For example, when the air tank 21 inflates the corresponding tire 40 alone, the controller 50 controls the air pump 11 to remain in a stopped state, opens the inflation valve 33 and the corresponding control valve 34, and at this time, the gas inside the air tank 21 flows into the corresponding inflation gas path through the inflation valve 33, thereby performing an inflation operation on the tire 40.

[0071] Taking the inflating of the left front wheel tire 41 as an example, when the controller 50 receives the inflation instruction for the left front wheel tire 41, the inflation operation of the left front wheel tire 41 is performed. First, the controller 50 controls the inflation valve 33 to open, and the high-pressure gas in the air tank 21 flows through the inflation valve 33 into the central air path inside the integrated valve 31. At this time, the high-pressure gas in the air tank 21 will be enclosed in the space formed by the air tank 21, the inflation valve 33, the air pressure sensor 318 and the central air path of the integrated valve. The air pressure sensor 318 can measure the internal pressure value of the air tank 21, and then perform the pressure measurement operation on the air tank 21 through the air pressure sensor 318 in the integrated valve 31. When it is determined that the pressure value in the air tank 21 reaches the first preset pressure value P1, the controller 50 controls the first control valve 312 to open, and the high-pressure gas in the air tank 21 passes through the inflation valve 33, the first control valve 312, and the left front wheel rotating sealing device 411 in sequence to reach the first safety valve 321. The first safety valve 321 opens under the action of air pressure, so that the high-pressure gas in the air tank 21 is introduced into the left front wheel tire 41 to inflate the left front wheel tire 41.

[0072] That is to say, when the vehicle tire pressure active regulation system is inflating the corresponding tire, if it is determined that the pressure value of the air tank 21 reaches the first preset pressure value P1 and the air pressure in the air tank 21 is sufficient, the air tank 21 is preferentially used to perform rapid inflation on the corresponding tire.

[0073] In one embodiment of the present application, the controller 50 is further used to determine the inflation rate of the tire 40 when the corresponding tire is inflated through the air tank 21, and when the inflation rate is less than the first preset inflation rate V1, control the air valve module 30 to stop inflating the tire 40 through the air tank 21. The first preset inflation rate V1 can be set according to actual conditions, for example, the first preset inflation rate V1 can be set to 0.4 kpa / s.

[0074] Continue to Figure 4Taking the inflation of the left front wheel tire 41 in the figure as an example, during the process of the air tank 21 inflating the left front wheel tire 41, the inflation rate of the left front wheel tire 41 is obtained in real time, and can be specifically calculated by the tire pressure value obtained by the first tire pressure monitoring sensor 61. For example, the tire pressure value of the left front wheel tire 41 determined before the air tank 21 inflates the left front wheel tire 41 is P01, and the tire pressure value of the left front wheel tire 41 obtained after the air tank 21 inflates the left front wheel tire 41 for t1 time is P02. The inflation rate of the left front wheel tire 41 can be calculated by the formula (P02-P01) / t1. The inflation rate is then compared with the first preset inflation rate V1. If the inflation rate is less than the first preset inflation rate V1, it is considered that the inflation rate is too small and the air pressure in the air tank 21 is insufficient. The controller 50 controls the first control valve 312 to be closed, or controls the inflation valve 33 and the first control valve 312 to be closed at the same time to stop the air tank 21 from continuing to inflate the left front wheel tire 41.

[0075] Further, if the inflation rate is greater than or equal to the first preset inflation rate V1, the controller 50 continues to inflate the left front wheel tire 41 with the air tank 21 until the tire pressure value of the left front wheel tire 41 reaches the target tire pressure. The controller 50 determines that the inflation is completed, controls the inflation valve 33 to be closed, so as to stop the outflow of the compressed gas in the air tank 21, and realizes the inflation stop. Then, the pressure-maintaining valve 316 is controlled to be turned on, wherein the pressure-maintaining valve 316 is a quick release valve. Therefore, after the pressure-maintaining valve 316 is turned on, the left front wheel tire 41 is connected to the atmosphere through the first safety valve 321, the left front wheel rotary sealing device 411, the first control valve 312 and the pressure-maintaining valve 316, so as to realize rapid pressure relief. The first safety valve 321 is reset and closed under the action of air pressure. After determining that the first safety valve 321 is reset and closed, the controller 50 controls the first control valve 312 to be turned off, thereby completing the inflation and pressure-maintaining action.

[0076] In one embodiment of the present application, the first air source 10 includes an air pump 11, and the controller 50 is also used to control the air valve module 30 to inflate the corresponding tire through the air pump 11 when the pressure value of the air tank 21 is less than the first preset pressure value P1, if the air pump 11 is normal.

[0077] That is to say, when the controller 50 inflates the corresponding tire, if the pressure value of the air tank 21 is less than the first preset pressure value P1, it is considered that the current air pressure in the air tank 21 is insufficient, and the air source pressure generated by the air pump 11 is further judged. If the air source pressure generated by the air pump 11 is normal, the air valve module 30 is controlled to perform regular inflation on the corresponding tire through the compressed gas generated by the air pump 11.

[0078] Continue to Figure 4Taking the inflation operation of the left front wheel tire 41 in the example, after the controller 50 determines that the air pressure value of the air tank 21 is less than or equal to the first preset pressure value P1 based on the pressure value obtained by the air pressure sensor 318, the inflation valve 33 is controlled to be closed, and the inflation pump 11 is started. The compressed gas generated by the inflation pump 11 flows into the integrated valve 31, and the air source pressure generated by the inflation pump 11 is detected by the air pressure sensor 318. If it is determined that the pressure of the inflation pump 11 is normal, the controller 50 controls the first control valve 312 to open, and the compressed gas generated by the inflation pump 11 reaches the first safety valve 321 through the first control valve 312 and the left front wheel rotating sealing device 411. The first safety valve 321 opens under the action of pressure to allow the compressed gas generated by the inflation pump 11 to enter the left front wheel tire 41 to inflate the left front wheel tire 41.

[0079] That is to say, when the vehicle tire pressure active regulation system is performing tire inflation, if it is determined that the pressure of the air tank 21 is insufficient, but the pressure of the air pump 11 is normal, the air pump 11 is used to perform conventional inflation on the corresponding tire.

[0080] In one embodiment of the present application, the controller 50 is further used to determine the inflation rate of the tire 40 when the corresponding tire 40 is inflated by the air pump 11, and when the inflation rate is less than the second preset inflation rate V2, control the air valve module 30 to stop inflating the tire 40 by the air pump 11. The second preset inflation rate V2 can be set according to actual conditions.

[0081] That is, during the process of the air pump 11 inflating the tire 40, the inflation rate of the corresponding tire 40 is monitored in real time. If it is determined that the inflation rate is less than the second preset inflation rate V2, the air pump 11 is stopped to continue to inflate the tire.

[0082] For example, the air pump 11 is used to Figure 4 Taking the inflation operation of the left front wheel tire 41 in the example, the inflation rate of the left front wheel tire 41 during the inflation process is calculated according to the tire pressure value obtained in real time by the first tire pressure monitoring sensor 60, and the inflation rate is compared with the second preset inflation rate V2. If the inflation rate is greater than or equal to the second preset inflation rate V2, the controller 50 continues to control the air pump 11 to continue to inflate the left front wheel tire 41 until the tire pressure value of the left front wheel tire 41 reaches the target tire pressure, and the inflation is determined to be completed, and then the air pump 11 is controlled to stop working, and the pressure-maintaining action is further performed on the left front wheel tire 41 by controlling the pressure-maintaining valve 316, so that the inflation and pressure-maintaining action is completed. If the inflation rate is less than the second preset inflation rate V2, the controller 50 directly controls the air pump 11 to stop working, and controls the first control valve 312 to be turned off, so as to stop the air pump 11 from continuing to inflate the left front wheel tire 41.

[0083] In one embodiment of the present application, the first air source 10 includes an air pump 11 , and the controller 50 is further used to control the air valve module 30 to replenish air and increase pressure in the air storage tank 21 through the air pump 11 after stopping inflating the tire 40 .

[0084] Continue to Figure 4 Taking the inflation of the left front wheel tire 41 as an example, after the air tank 21 or the air pump 11 stops inflating the left front wheel tire 41 due to the low inflation rate, the controller 50 controls the inflation valve 33 to be turned on and controls the air pump 11 to work. At this time, the compressed gas output by the air pump 11 only flows into the air tank 21 through the inflation valve 33 to replenish and pressurize the air tank 21.

[0085] During the process of the air pump 11 replenishing and pressurizing the air tank 21, if it is determined that the pressure value of the air tank 21 reaches the preset pressure value, indicating that the internal pressure of the air tank 21 is sufficient, the air pump 11 is controlled to stop working. At this time, the controller 50 can control the air valve module 30 to allow the air tank 21 with sufficient pressure to continue to quickly inflate the left front wheel tire 41, or control the air pump 11 and the air tank 21 to inflate the left front wheel tire 41 to speed up the inflation efficiency.

[0086] In one embodiment of the present application, the controller 50 is further used to obtain the pressure value of the air tank 21 when the air tank 21 is supplemented with air and pressurized by the air pump 11, and when the pressure value of the air tank 21 is greater than or equal to the second preset pressure value P2, control the air valve module 30 to inflate the tire 40 through the air tank 21 and the air pump 11. The second preset pressure value P2 can be set according to actual conditions.

[0087] In other words, continue to Figure 4 Taking the inflating of the left front wheel tire 41 in the figure as an example, when the air pump 11 performs air replenishment and pressurization on the air tank 21 through the inflation valve 33, the controller 50 performs real-time detection of the pressure value of the air tank 21 based on the air pressure sensor 318. When it is determined that the pressure value of the air tank 21 reaches the second preset pressure value P2, it is considered that the pressure of the gas stored in the air tank 21 is sufficient. The controller 50 controls the inflation pump 11, the inflation valve 33, and the first control valve 312 to open, so as to inflate the left front wheel tire 41 through the air tank 21 and the inflation pump 11 at the same time, thereby increasing the inflation rate and performing extreme inflation of the left front wheel tire 41.

[0088] In one embodiment of the present application, the controller 50 is also used to determine the inflation rate of the tire 40 when the tire 40 is inflated by the air tank 21 and the air pump 11, and when the inflation rate is less than a third preset inflation rate V3, control the air valve module 30 to stop inflating the tire 40 by the air tank 21 and the air pump 11.

[0089] Specifically, continue to Figure 4 Taking the inflation of the left front wheel tire 41 in the example, when the controller 50 controls the air tank 21 and the air pump 11 to perform extreme inflation on the left front wheel tire 41, the inflation rate is calculated based on the tire pressure value of the left front wheel tire 41 obtained by the first tire pressure detection sensor 61 before and after the preset time interval, and the calculated inflation rate is compared with the third inflation rate V3. If the inflation rate is less than the third preset inflation rate V3, it is considered that the inflation rate is too small, and the "extreme inflation" inflation is abnormal. The controller 50 controls the air pump 11 to stop working, and controls the inflation valve 33 and the first control valve 312 to be turned off, so as to stop the inflation action of the air pump 11 and the air tank 21 on the left front wheel tire 41.

[0090] In one embodiment of the present application, the controller 50 is further configured to report a fault when controlling the air valve module 30 to stop inflating the tire 40 through the air tank 21 and the air pump 11 .

[0091] That is to say, during the process of extreme inflation of the left front wheel tire 41 through the air tank 21 and the air pump 11, when the inflation rate is less than the third preset inflation rate V3, the controller 50 controls the air pump 11 and the air tank 21 to stop inflating the left front wheel tire 41, and at the same time issues a corresponding fault code to provide a fault reminder.

[0092] If during the extreme inflation process, the inflation rate is greater than or equal to the third preset inflation rate V3, the controller 50 continues to control the air tank 21 and the air pump 11 to inflate the left front wheel tire 41 until the tire pressure value of the left front wheel tire 41 reaches the target tire pressure, and the controller 50 controls the air pump 11 to stop working, and controls the inflation valve 33 to be turned off, and the pressure-maintaining valve 316 to be opened. At this time, the left front wheel tire 41 is quickly depressurized to the atmosphere through the first safety valve 321, the left front wheel rotary sealing device 411, the first control valve 312, and the pressure-maintaining valve 316. The first safety valve 321 is reset and closed under the action of pressure, thereby completing the pressure-maintaining action of the left front wheel tire 41, and the controller 50 controls the first control valve 312 and the pressure-maintaining valve 316 to be turned off.

[0093] It should be further explained that, during the process of rapid inflation of the tire 40 through the air tank 21, conventional inflation of the tire through the air pump 11, and extreme inflation of the tire 40 through the air tank 21 and the air pump 11, if the inflation rate is determined to be too small based on the inflation rate and it is necessary to stop the tire inflation, the controller 50 may also perform a pressure maintaining action on the corresponding tire by controlling the air valve module 30 to avoid internal gas leakage of the tire.

[0094] In one embodiment of the present application, the controller 50 is also used to obtain the tire pressure when inflating the tire 40, and control the air valve module 30 to maintain the pressure of the tire 40 when it is determined that the tire pressure meets the preset tire pressure requirement.

[0095] That is to say, during the process of inflating the tire 40, when the controller 50 determines that the tire pressure value of the inflated tire 40 reaches the target tire pressure, it is considered that the tire pressure meets the preset tire pressure requirement, and the controller 50 stops inflating and performs the pressure-maintaining action on the tire 40. Taking the inflating action of the left front wheel tire 41 as an example, when it is determined that the tire pressure value of the left front wheel tire 41 reaches the target tire pressure, the controller 50 controls the inflation valve 33 to be closed, and controls the pressure-maintaining valve 316 to be turned on, and the left front wheel tire 41 is connected to the atmosphere through the first safety valve 321, the left front wheel rotary sealing device 411, the first control valve 312 and the pressure-maintaining valve 316 to achieve rapid pressure relief, and the first safety valve 321 is reset and closed under the action of air pressure. After determining that the first safety valve 321 is reset and closed, the controller 50 controls the first control valve 312 to be closed, and the inflation and pressure-maintaining action is completed.

[0096] In one embodiment of the present application, the first air source includes an air pump, and the controller is further used to control the air valve module to replenish air and increase pressure in the air storage tank through the air pump when the tire pressure value is within the target tire pressure range. The target tire pressure range can be set according to actual conditions. When the tire pressure value is within the target tire pressure range, it is considered that the tire pressure of the tire is normal and no pressure adjustment is required.

[0097] Specifically, when the tire pressure values ​​of all tires in the vehicle are within the target tire pressure range, it is considered that the tire pressure of each tire of the vehicle is normal, and there is no need to perform inflation, deflation, pressure maintenance and other actions. That is, when the vehicle tire pressure active adjustment system is in an idle state, the controller 50 controls the inflation valve 33 to be turned on, and the inflation pump 11 to work. The compressed gas discharged by the inflation pump 11 flows into the air tank 21 through the inflation valve 33, so as to replenish air and pressurize the air tank 21 through the inflation pump 11, so as to facilitate the application of subsequent pressure adjustment actions.

[0098] Furthermore, when the vehicle tire pressure active regulation system is in an idle state, for example, when the tire pressure of each tire is normal and no inflation, deflation, or pressure-maintaining actions are performed, the controller 50 can control the inflation valve 33 to be turned on at a fixed time interval (such as every 4 hours in the ignition cycle), and after opening the air valve 311, the high-pressure gas in the air tank 21 flows through the inflation valve 33 and enters the central air path of the integrated valve 31. At this time, the high-pressure gas in the air tank 21 will be enclosed in the space formed by the air tank 21, the inflation valve 33, the air pressure sensor 316, and the central air path of the integrated valve, and the air pressure sensor 316 can measure the internal pressure value of the air tank 21. When it is determined that the pressure stored in the air tank 21 is insufficient, the controller 50 controls the air pump 11 to turn on, and replenishes air and pressurizes the air tank 21. At the same time, the air pressure sensor 316 collects the pressure value in the central air circuit in real time. When it is determined that the pressure value in the central air circuit reaches the target pressure value, it is determined that the inflation in the air tank 21 is completed, and the air pump 11 and the inflation valve 33 are controlled to close, ending the air replenishment and pressurization action of the air tank 21, thereby maintaining the air pressure in the air tank 21.

[0099] In addition, in addition to the above-mentioned case where the tire pressure values ​​of each tire of the vehicle are within the target tire pressure range, that is, the vehicle tire pressure active regulation system is in an idle state, the air tank 21 is supplemented with air and pressurized by the air pump 11, the vehicle tire pressure active regulation system can also inflate the corresponding tire and determine that the inflation is completed when the tire pressure value of the tire is within the target tire pressure range. After the inflation action is completed, the controller 50 controls the air valve module 30 to first supplement the air tank 21 with air and pressurize it through the air pump 11 to ensure that the pressure value in the air tank 21 meets the subsequent inflation requirements. The specific control can be set according to actual needs and is not limited here.

[0100] In one embodiment of the present application, the controller 50 is further configured to stop inflating the corresponding tire 40 when the pressure value of the air tank 21 is less than the first preset pressure value P1 and if the air pump 21 is abnormal.

[0101] That is, when the controller 50 receives the corresponding inflation instruction and inflates the corresponding tire, if the pressure of the air tank 21 is insufficient and the air source pressure generated by the inflation pump 11 is abnormal, the controller 50 stops inflating.

[0102] In one embodiment of the present application, the controller 50 is further configured to report a fault when the corresponding tire 40 stops being inflated.

[0103] That is to say, during the process of inflating the corresponding tire, when the pressure in the air tank 21 is insufficient and the air source pressure generated by the air pump 11 is abnormal, the controller 50 controls the air valve module 20 to stop the inflation process and issues a corresponding fault code to remind the user.

[0104] In summary, according to the vehicle tire pressure active regulation system of the embodiment of the present application, the first air source and the second air source are respectively connected to each tire of the vehicle through the air valve module, and the controller controls the air valve module to make at least one of the first air source and the second air source work to regulate the tire pressure of the corresponding tire. Therefore, the vehicle tire pressure active regulation system regulates the tire pressure by controlling at least one of the first air source and the second air source to work, thereby ensuring the air regulation rate and improving the user experience.
