[0055] The embodiments of the present application are described in detail below. 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.

[0056] With the rapid development of intelligent vehicles, users are increasingly demanding a wider range of driving conditions, and driving strategies for different road conditions are becoming increasingly complex. During driving, changes in tire pressure can affect the contact area between the tire and the ground, changing the contact area between the tire and the ground.

[0057] In related technologies, it is difficult for vehicles to automatically adjust tire pressure. They can only detect the tire pressure status and issue warnings for abnormal tire pressure. Users need to adjust the tire pressure by themselves, which is a complicated operation.

[0058] Based on the above issues to be resolved, please refer to Figure 1 and Figure 2 The embodiment of the present application provides a tire pressure control method for a tire 100 of a vehicle 1000, the tire pressure control method comprising:

[0059] 01: Determine a target tire pressure of the tire 100 according to state parameters and / or environmental parameters of the vehicle 1000;

[0060] 02: Control the tire 100 to inflate or deflate according to the target tire pressure.

[0061] Embodiments of the present application provide an electronic device comprising one or more processors and a memory, wherein the memory stores a computer program executable by the processor. The processor may be configured to: determine a target tire pressure for a tire 100 based on vehicle 1000 status parameters and / or environmental parameters; and control tire 100 inflation and deflation based on the target tire pressure.

[0062] Embodiments of the present application provide a tire pressure control device, comprising a first determination module and a first control module. The first determination module is operable to determine a target tire pressure for a tire 100 based on state parameters and / or environmental parameters of a vehicle 1000; and the first control module is operable to control the inflation and deflation of the tire 100 based on the target tire pressure.

[0063] The present embodiment provides a tire pressure control system 300, which includes a tire pressure determination module 310 and an inflation / deflation module 330. The tire pressure determination module 310 is configured to determine a target tire pressure for the vehicle 1000 based on state parameters and / or environmental parameters of the vehicle 1000; the inflation / deflation module 330 is configured to control the inflation / deflation of the tires 100 of the vehicle 1000 based on the target tire pressure.

[0064] Specifically, the target tire pressure can be determined based on the state parameters and / or environmental parameters of vehicle 1000. That is, the target tire pressure can be determined based on the state parameters of vehicle 1000. Alternatively, the target tire pressure can be determined based on the environmental parameters of vehicle 1000. Alternatively, the target tire pressure can be determined based on both the state parameters and environmental parameters of vehicle 1000.

[0065] The state parameters of vehicle 1000 include the dynamic parameters of vehicle 1000 and the mode of vehicle 1000. Environmental parameters include the ambient temperature, humidity, and weather of the environment in which vehicle 1000 is located, as well as the surface conditions of the road on which vehicle 1000 is traveling. Based on the state parameters of vehicle 1000 and the environmental parameters, a target tire pressure suitable for the current situation of tire 100 can be automatically determined. The tire 100 is then inflated and deflated according to the target tire pressure to ensure that the tire pressure of tire 100 reaches the target tire pressure.

[0066] The target tire pressure can be the tire pressure of a single tire 100, or it can be determined based on the average tire pressure of the four tires 100. Controlling the tire 100 to inflate or deflate according to the target tire pressure refers to inflating or deflation of a single tire 100. For example, a vehicle 1000 includes four tires 100, and a target tire pressure is determined for each tire 100. Then, each tire 100 is controlled to inflate or deflate according to the corresponding target tire pressure. In other words, the target average value for each tire 100 can be different. For another example, a single target tire pressure can be determined, and then each tire 100 is controlled to inflate or deflate according to the target tire pressure. In other words, the target average value for each tire 100 is the same.

[0067] The tire 100 includes a tire elastic body 101 and a wheel hub 103. The inflation and deflation module 330 is disposed on the tire elastic body 101.

[0068] In some embodiments, tire pressure control system 300 includes a vehicle detection module 350 and an environment detection module 370. Vehicle detection module 350 is configured to determine state parameters, while environment detection module 370 is configured to determine environmental parameters. In some embodiments, the tire pressure detection method of the present application can be implemented by an electronic control unit (ECU) of vehicle 1000.

[0069] In related technologies, tire pressure monitoring systems are only capable of detecting tire pressure, alerting drivers of abnormal pressure, and reminding them to adjust tire 100 pressure themselves. Tire pressure control systems 300 only offer manually controlled, tiered tire pressure control options. Users must independently categorize road conditions and manually select system-defined pressure options to adjust tire pressure. There is no real-time feedback between tire pressure and vehicle 1000 status parameters, nor is there a way to automatically determine the optimal tire pressure based on vehicle 1000 status and environmental parameters. Users must analyze and determine the optimal tire pressure themselves, then instruct vehicle 1000 to adjust accordingly.

[0070] In the embodiments of the present application, the most appropriate target tire pressure can be determined based on the real-time state parameters of vehicle 1000 and environmental parameters, and the tire pressure of tire 100 can be automatically adjusted based on the target tire pressure, simplifying the user's tire pressure adjustment operation. Furthermore, the determined target tire pressure is based on the real-time state parameters of vehicle 1000 and environmental parameters, which can more effectively adapt to the current state and environment of vehicle 1000.

[0071] It should be noted that the embodiment of the present application can also determine the target tire pressure based on other parameters of the vehicle and its environment, which is not limited here.

[0072] Tire 100 includes a single-chamber tire or a multi-chamber tire. The tire pressure control method of the embodiment of the present application can be used for single-chamber tires or multi-chamber tires. The single-chamber tire includes an inflation / deflation valve. By controlling the inflation / deflation valve, the inflation / deflation of the entire tire 100 of the single-chamber tire can be controlled. The multi-chamber tire includes multiple sub-chambers 111. Each sub-chamber 111 is equipped with a sub-inflation / deflation valve. By controlling the inflation / deflation of the sub-inflation / deflation valve, the air pressure within the sub-chamber 111 can be controlled, thereby adjusting the tire pressure of the entire multi-chamber tire.

[0073] In this way, by determining the target tire pressure of vehicle 1000 based on the state parameters and environmental parameters of vehicle 1000, and then adjusting the tire 100 of vehicle 1000 according to the target tire pressure, the tire pressure of tire 100 can be automatically adjusted without the user having to adjust it himself, which simplifies the complexity of user operations and improves user experience.

[0074] See also Figure 3 and Figure 4 In some embodiments, the tire 100 includes a plurality of sub-chambers 111. Step 02, controlling the tire 100 to inflate and deflate according to a target tire pressure, includes:

[0075] 021: Determine the chamber pressure of each sub-chamber 111 according to the target tire pressure;

[0076] 022: According to the chamber air pressure, control the sub-chamber 111 corresponding to the tire 100 to inflate or deflate.

[0077] In some embodiments, the processor may be configured to: determine the chamber pressure of each sub-chamber 111 according to the target tire pressure; and control the inflation and deflation of the corresponding sub-chamber 111 of the tire 100 according to the chamber pressure.

[0078] In some embodiments, the first control module includes a first determination submodule and a first control submodule. The first determination submodule can be used to determine the chamber pressure of each subchamber 111 based on the target tire pressure; the first control submodule can be used to control the inflation or deflation of the corresponding subchamber 111 of the tire 100 based on the chamber pressure.

[0079] In some embodiments, the tire 100 includes multiple sub-chambers 111, and the inflation and deflation module 330 includes an inflation and deflation assembly 331. Each sub-chamber 111 is configured with a corresponding inflation and deflation assembly 331, and the inflation and deflation assembly 331 is configured to inflate and deflate the sub-chamber 111.

[0080] Specifically, a single tire 100 includes multiple subchambers 111. Each subchamber 111 is isolated and distinct from the others, and the air pressure within each subchamber 111 does not affect the other subchambers 111. By providing multiple subchambers 111, the tire 100 can be compartmentalized, preventing a leak in one area of the tire 100 from rendering the entire tire 100 unusable, thereby improving the safety of the tire 100.

[0081] Each subchamber 111 is equipped with at least one inflation / deflation assembly 331. Each inflation / deflation assembly 331 includes an inflation / deflation valve. By controlling the inflation / deflation valve, the air pressure within each subchamber 111 can be adjusted. By adjusting the air pressure in each of the multiple subchambers 111, the air pressure of the entire tire 100 can be controlled.

[0082] After determining the target tire pressure for a single tire 100, the pressure in each sub-chamber 111 of the tire 100 can be determined based on the target tire pressure. After the pressure is determined, the corresponding sub-chamber 111 is inflated or deflated based on the pressure to achieve the desired pressure condition.

[0083] Thus, by providing multiple sub-chambers 111 within the tire 100 and individually controlling the inflation and deflation of each sub-chamber 111, accurate inflation and deflation of various parts of the tire 100 can be achieved. This also prevents damage to a particular part of the tire 100 from causing a leak or blowout of the entire tire 100, rendering the entire tire 100 unusable, thereby improving the safety of the tire 100.

[0084] See also Figure 5 In some embodiments, the tire 100 includes a plurality of chambers 110 , each chamber 110 includes a plurality of sub-chambers 111 , and the tire pressure control method further includes:

[0085] 03: Determine the target contact state of the tire 100 according to the state parameters of the vehicle 1000 and the environmental parameters;

[0086] Step 021, determining the chamber pressure of each sub-chamber 111 according to the target tire pressure, includes:

[0087] 0211: Determine the chamber air pressure of the sub-chamber 111 corresponding to each chamber 110 according to the target contact state and the target tire pressure.

[0088] In some embodiments, the processor may be configured to: determine a target contact state of the tire 100 based on state parameters and environmental parameters of the vehicle 1000; and determine the chamber air pressure of the sub-chamber 111 corresponding to each chamber 110 based on the target contact state and target tire pressure.

[0089] In certain embodiments, the tire pressure control device further includes a second determination module, and the first determination submodule includes a determination unit. The second determination module can be configured to determine a target contact state of the tire 100 based on state parameters of the vehicle 1000 and environmental parameters; and the determination unit can be configured to determine the chamber pressure of the subchamber 111 corresponding to each chamber 110 based on the target contact state and the target tire pressure.

[0090] Specifically, the tire may include a plurality of chambers. In one embodiment, along the axial direction of the tire, the tire includes a plurality of chambers distributed sequentially.

[0091] The contact state between the tire 100 and the ground affects the adhesion of the tire 100 to the ground, thereby affecting the power of the vehicle 1000. For example, when the inner and outer sides of the tire 100 in the axial direction have more contact with the ground, the contact area between the tire 100 and the ground is larger, and the adhesion of the tire 100 is stronger. When the inner and outer sides of the tire 100 in the axial direction have less contact with the ground, the contact area between the tire 100 and the ground is smaller, and the adhesion of the tire 100 is weaker. Therefore, by dividing the tire 100 into multiple chambers 110 along the axial direction, the chamber pressure of the sub-chambers 111 corresponding to each chamber 110 can be determined separately to achieve more precise control of the tire 100.

[0092] Based on the state parameters of vehicle 1000 and environmental parameters, a suitable contact state between tire 100 and the ground can be determined as a target contact state. Based on the target contact state and target tire pressure, the chamber pressure of sub-chamber 111 corresponding to each chamber 110 can be determined.

[0093] The contact state refers to the equivalent contact surface between the tire 100 and the ground, which is related to the air pressure difference between the inner and outer chambers 110 of the tire 100 .

[0094] In some embodiments, the tire 100 includes a first chamber 1101, a second chamber 1102, and a third chamber 1103, and the first chamber 1101, the second chamber 1102, and the third chamber 1103 each include multiple sub-chambers 111; the air pressure of the sub-chamber 111 of the first chamber 1101, the air pressure of the sub-chamber 111 of the second chamber 1102, and the air pressure of the sub-chamber 111 of the third chamber 1103 can be different.

[0095] In the axial direction of the tire 100 and in the direction toward the interior of the vehicle 1000, the first chamber 1101 can be the outer chamber 110 of the tire 100, the second chamber 1102 can be the middle chamber 110, and the third chamber 1103 can be the inner chamber 110. By setting different air pressures in the first chamber 1101, the second chamber 1102, and the third chamber 1103, the contact state between the tire 100 and the ground can be changed, that is, the contact area between the tire 100 and the ground can be changed.

[0096] In one embodiment, along the axial direction of the tire 100 and inward of the vehicle 1000, the chamber pressures of the outer chamber 110 and the inner chamber 110 of the tire 100 are greater than the chamber pressure of the middle area, so that the contact area between the tire 100 and the ground is smaller, the adhesion of the tire 100 is smaller, and the fuel economy of the vehicle 1000 is increased.

[0097] In another embodiment, along the axial direction of the tire 100 and in the direction toward the interior of the vehicle 1000, the chamber pressures of the outer chamber 110 and the inner chamber 110 of the tire 100 are slightly smaller than the chamber pressure in the middle area, so that the contact area between the tire 100 and the ground is larger, the adhesion of the tire 100 is greater, and the dynamic performance of the vehicle 1000 is stronger.

[0098] In some embodiments, the tire pressure control system 300 further includes an air pressure detection module 390, which is configured to detect the current air pressure of the tire 100 in real time. The air pressure detection module 390 may be a pressure sensor.

[0099] Furthermore, the target tire pressure is the equivalent total tire pressure when the tire 100 is a multi-chamber tire. Then, the target tire pressure can be calculated based on the mapping function G from the equivalent total tire pressure and the contact state of the tire 100 to the chamber pressure of each sub-chamber 111. -1 (F T (t) ), the chamber pressure of each sub-chamber 111 is determined according to the target tire pressure and the target contact state. T(t) is the equivalent total tire pressure and contact state of the tire 100. T(t) is a time function based on the acquisition frequency of the air pressure detection module 390 and the acquisition frequency of each module of the ECU.

[0100] The equivalent total tire pressure is related to the chamber air pressure values of all sub-chambers 111 of the tire 100 .

[0101] In one embodiment, the mapping function G(P) from the chamber pressure of each sub-chamber 111 to the relationship between the total tire pressure of the tire 100 and the contact state is prepared in advance. T(t) a1 ,P T(t) a2 ,P T(t) a3 ,...,P T(t) an ,P T(t) b1 ,P T(t) b2 ,P T(t) b3 ,...,P T(t) bn ,P T (t)c 1,P T(t) c2 ,P T(t) c3 ,...,P T(t) cn ,P T(t) d1 ,P T(t) d2,P T(t) d3 ,...,P T(t) dn ) for calibration. Among them, the air pressure of each chamber P T(t) ij The i represents the wheel number (the default is a, b, c, d for a four-wheel vehicle 1000), and j represents the chamber 110 number of the wheel. T(t) ai is the chamber pressure of the i-th sub-chamber 111 of the first tire 100a, P T(t) bi is the chamber pressure of the i-th sub-chamber 111 of the second tire 100b, P T(t) ci is the chamber pressure of the i-th sub-chamber 111 of the third tire 100c, P T (t) di is the chamber pressure of the i-th sub-chamber 111 of the fourth tire 100d, 1≤i≤n. Then find the inverse function of G and get G -1 (F T (t) ) and pre-stored in the processor. After determining the target tire pressure and target contact state, based on G -1 (F T(t) ) can obtain the chamber pressure of each sub-chamber 111.

[0102] In addition, by adjusting the air pressure of the sub-chambers of the plurality of chambers 110 , the wear uniformity of the tire 100 can be improved, thereby increasing the durability and life of the tire 100 .

[0103] In this way, the target contact state of the tire 100 with the ground can be determined based on the vehicle 1000's state parameters and environmental parameters. Furthermore, the air pressure of each sub-chamber 111 corresponding to each chamber 110 can be determined based on the target contact state and target tire pressure. By controlling the air pressure of each sub-chamber 110, the dynamic performance of the vehicle 1000 can be effectively improved.

[0104] See also Figure 6 In some embodiments, step 022, controlling the inflation and deflation of the sub-chamber 111 corresponding to the tire 100 according to the chamber air pressure, includes:

[0105] 0221: When the chamber air pressure is different from the current air pressure of the corresponding sub-chamber 111, the sub-chamber 111 corresponding to the tire 100 is controlled to be inflated or deflated according to the chamber air pressure.

[0106] In some embodiments, the processor may be configured to control the inflation and deflation of the corresponding sub-chamber 111 of the tire 100 according to the chamber air pressure when the chamber air pressure is different from the current air pressure of the corresponding sub-chamber 111 .

[0107] In some embodiments, the first control submodule includes a control unit configured to control the inflation or deflation of the corresponding subchamber 111 of the tire 100 according to the chamber air pressure when the chamber air pressure differs from the current air pressure of the corresponding subchamber 111 .

[0108] In some embodiments, the tire pressure control system 300 also includes an air pressure control module 3110, which is used to compare the chamber air pressure and the current air pressure of the corresponding sub-chamber 111, and when the chamber air pressure and the current air pressure of the corresponding sub-chamber 111 are different, control the inflation and deflation of the sub-chamber 111 corresponding to the tire 100 according to the chamber air pressure.

[0109] Specifically, for a multi-chamber tire, the air pressure detection module 390 includes multiple air pressure detection components, each of which is disposed in a sub-chamber 111 to detect the current air pressure inside the sub-chamber 111. The air pressure detection component detects and obtains the current air pressure P of each sub-chamber 111. T(t) a1 ,P T(t) a2 ,P T(t) a3 ,...,P T(t) an ,P T(t) b1 ,P T(t) b2 ,P T(t) b3 ,...,P T(t) bn ,P T(t)c 1,P T(t) c2 ,P T(t) c3 ,...,P T(t) cn ,P T(t) d1 ,P T(t) d2 ,P T(t) d3 ,...,P T(t) dn The current air pressure is uploaded to the ECU, which can compare the current air pressure with the chamber pressure.

[0110] If the chamber pressure is the same as the current pressure, there is no need to adjust the pressure by inflating or deflating the chamber, just maintain the current pressure.

[0111] If the chamber pressure is different from the current pressure of the corresponding sub-chamber 111 , the corresponding sub-chamber 111 is controlled to be inflated or deflated according to the chamber pressure, so as to adjust the pressure of the sub-chamber 111 to the chamber pressure.

[0112] In this way, only when the chamber pressure is different from the current pressure does it need to control the sub-chamber 111 to be inflated or deflated, thereby simplifying the control operation.

[0113] See also Figure 7 In some embodiments, step 02, controlling the tire 100 of the vehicle 1000 to inflate or deflate according to the target tire pressure, includes:

[0114] 023: When the target tire pressure and the current tire pressure of the tire 100 are different, the tire 100 of the vehicle 1000 is controlled to be inflated or deflated according to the target tire pressure.

[0115] In some embodiments, the processor may be configured to control the inflation and deflation of the tire 100 of the vehicle 1000 according to the target tire pressure when the target tire pressure is different from the current tire pressure of the tire 100 .

[0116] In some embodiments, the first control module further includes a second control submodule configured to control the inflation and deflation of the tire 100 of the vehicle 1000 according to the target tire pressure when the target tire pressure is different from the current tire pressure of the tire 100 .

[0117] Specifically, for a single-chamber tire, the air pressure detection module 390 may include only one air pressure detection component to monitor the current tire pressure inside the tire 100. If the current tire pressure of the tire 100 is the same as the target tire pressure, there is no need to inflate or deflate the tire 100. Only when the current tire pressure of the tire 100 is different from the target tire pressure is it necessary to control the inflation or deflation of the tire 100.

[0118] In this way, by judging the target tire pressure and the current tire pressure, it can be determined whether the tire 100 needs to be inflated or deflated. Inflation or deflation is only required when the current tire pressure and the target tire pressure are different, thereby simplifying the control operation.

[0119] See also Figure 8 In some embodiments, step 03, determining the target tire pressure of the vehicle 1000 based on the state parameters and / or environmental parameters of the vehicle 1000, includes:

[0120] 031: Determine a target tire pressure based on at least one of the power parameters of the vehicle 1000, the driving mode, the environmental state parameters, and the terrain state of the road on which the vehicle 1000 is traveling.

[0121] In some embodiments, the processor may be configured to determine a target tire pressure based on at least one of a power parameter of the vehicle 1000 , a driving mode, an environmental state parameter, and a terrain state of a road on which the vehicle 1000 is traveling.

[0122] In some embodiments, the second determination module includes a second determination submodule configured to determine the target tire pressure based on at least one of a power parameter of the vehicle 1000 , a driving mode, an environmental parameter, and a terrain condition of a road on which the vehicle 1000 is traveling.

[0123] Specifically, the state parameters include the power parameters and driving mode of vehicle 1000, and the environmental parameters include environmental state parameters and the terrain conditions of the road surface on which vehicle 1000 is traveling. The power parameters of vehicle 1000 include the dynamic state parameters of vehicle 1000. Driving modes include sports mode, economy mode, and low-power mode. Environmental state parameters include the weather, temperature, and humidity of the environment in which vehicle 1000 is located. The terrain conditions of the road surface on which vehicle 1000 is traveling include the terrain characteristics and degree of slipperiness of the road surface.

[0124] Based on at least one of the vehicle 1000's power parameters, driving mode, environmental parameters, and the terrain of the road on which the vehicle 1000 is traveling, the optimal target tire pressure for the current tire 100 can be determined to suit the vehicle 1000's current driving and environmental conditions. By considering these parameters to determine the target tire pressure, the optimal tire pressure can be automatically determined without requiring user analysis, thus eliminating subjectivity, simplifying user operations, and improving driving safety.

[0125] In this way, when determining the target tire pressure, considering at least one of the power parameters, driving mode, environmental state parameters, and terrain state of the road on which the vehicle 1000 is traveling can make the determined target tire pressure more consistent with the current state of the vehicle 1000 and improve the accuracy of the target tire pressure.

[0126] In some embodiments, the dynamic parameters include at least one of the vehicle speed of the vehicle 1000 , the wheel speed of the tire 100 , and the torque, and the environmental state parameters include at least one of the temperature, humidity, meteorological conditions, and atmospheric pressure of the environment in which the vehicle 1000 is located.

[0127] In some embodiments, the state parameters include at least one of the vehicle speed, driving mode, wheel speed and torque of the tire 100 of the vehicle 1000, and the vehicle detection module 350 includes a power detection module 351 and a driving mode recognition module 353. The power detection module 351 is configured to determine the vehicle speed, wheel speed and / or torque of the vehicle 1000, and the driving mode recognition module 353 is configured to identify the driving mode of the vehicle 1000.

[0128] In some embodiments, the environmental parameters include the terrain state of the road on which the vehicle 1000 is traveling, and at least one of the temperature, humidity, meteorological state, and atmospheric pressure of the environment in which the vehicle 1000 is located. The environmental detection module 370 includes a ground recognition module and an environmental detection module. The terrain recognition module is configured to identify the terrain state, and the environmental detection module is configured to determine at least one of the temperature, humidity, meteorological state, and atmospheric pressure of the environment in which the vehicle 1000 is located.

[0129] Specifically, the ECU may include a power detection module 351 , a driving mode recognition module 353 , an environment detection module, and a ground recognition module.

[0130] The power detection module 351 may be a dynamic sensor for detecting the current speed f of the vehicle 1000. T (t) 11 , the rotational speed f of the tire 100 T(t) 12 and the torque f of the drive motor T(t) 13 The ground recognition module is used to identify the ground state of the road on which the vehicle 1000 is currently traveling. T(t) 2. The environment detection module can be used to obtain cloud data, such as the weather conditions of the environment where the vehicle 1000 is located. T(t) 31 , temperature and humidity T(t) 32 , atmospheric pressure f T(t) 33 The driving mode recognition module 353 can obtain the driving mode K of the vehicle 1000 to determine the current driving mode of the vehicle 1000.

[0131] Furthermore, the ECU further includes a tire pressure determination module 310 for determining the equivalent total tire pressure of each wheel and the function F of the contact surface according to the state parameters and environmental parameters of the vehicle 1000. T (t) (F T(t) 1,F T(t) 2,F T(t)3,K), determine the target tire pressure and target contact state. Among them, F T(t) 1 is about f T(t) 11 ,f T (t) 12 ,f T(t) 13 ,...,f T(t) 1n Function, F T(t) 2 is about f T(t) 2 function, F T(t) 3 is about f T(t) 31 ,f T(t) 32 ,f T (t) 33 ,...,f T(t) 3n Function. f T(t) 1i is the power parameter of vehicle 1000, f T(t) 2 is the ground state of the road where the vehicle 1000 is currently traveling, f T(t) 3i It is the meteorological state parameter of the environment in which the vehicle 1000 is located.

[0132] For example, according to the vehicle speed f T(t) 11 , the rotational speed f of the tire 100 T(t) 12 and the torque f of the drive motor T(t) 13 , determine F T(t) 1. According to the ground state f of the road on which the vehicle 1000 is currently traveling T(t) 2. Determine F T(t) 2. According to the weather conditions of the environment where the vehicle 1000 is located T (t) 31 , temperature and humidity T(t) 32 , atmospheric pressure f T(t) 33 , determine F T(t) 3. According to F T(t) 1. F T(t) 2. F T(t) 3 obtained F T(t) That is, it is a function of the equivalent total tire pressure and contact area of each wheel based on different driving conditions of vehicle 1000 based on data such as wheel speed, vehicle speed, torque, etc., based on different terrains and based on different weather, temperature, humidity, and atmospheric pressure.

[0133] Among them, F T(t)(F T(t) 1,F T(t) 2,F T(t) 3, K) can be a set of pre-calibrated mappings from the state parameters and environmental parameters of the vehicle 1000 to the equivalent total tire pressure and contact surface, or it can be a real-time algorithm for determining the equivalent total tire pressure and contact surface based on the state parameters and environmental parameters of the vehicle 1000, which is used to calculate the target tire pressure and target contact state based on the state parameters and environmental parameters of the vehicle 1000.

[0134] In this way, the target tire pressure is determined based on the vehicle speed of vehicle 1000, the wheel speed and torque of tire 100, and at least one of the temperature, humidity, weather conditions, atmospheric pressure, and atmospheric pressure of the environment in which vehicle 1000 is located. This can make the target tire pressure more suitable for the current operating state and environmental state of vehicle 1000.

[0135] See also Figure 9 In some embodiments, the tire pressure control method further includes:

[0136] 04: When the duration of the tire 100 being inflated and deflated is greater than a set threshold, an alarm is issued.

[0137] In some embodiments, the processor may be configured to generate an alarm if the duration of the tire 100 being inflated or deflated is greater than a set threshold.

[0138] In some embodiments, the tire pressure control device includes a second control module that can be configured to issue an alarm when the duration of the tire 100 being inflated or deflated is greater than a set threshold.

[0139] In some embodiments, the tire pressure control system 300 further includes an alarm module 3130 , which is configured to issue an alarm if there is a fault in the tire 100 .

[0140] Specifically, the alarm module 3130 can be a generator or display component, etc., used to alert the user of a tire 100 malfunction. When the tire 100 begins to be inflated or deflated, a timer begins. If the duration of inflation or deflation exceeds a set threshold, it is determined that the tire 100 is leaking and cannot be effectively inflated or deflated. Therefore, the alarm module 3130 of the vehicle 1000 can be controlled to sound an alarm to alert the user of the tire 100 leak.

[0141] Furthermore, for a multi-chamber tire, each sub-chamber 111 is timed when being inflated or deflated, and the inflation and deflation time T of each sub-chamber 111 is obtained. T(t) ij (i=a, b, c or d, j=1, 2, ..., n) The filling and degassing time T of a certain sub-chamber 111T(t) ij Greater than the set time T k In the case of , it can be considered that there is air leakage in the sub-chamber 111. Although the tire 100 can continue to be used for a short time because other sub-chambers 111 have no faults, the alarm module 3130 can also be controlled to sound an alarm to remind the user to check in time.

[0142] In this way, based on the comparison result of the duration of inflation and deflation and the set time, it can be determined whether the tire 100 is leaking. If the duration is greater than the set threshold, it can be determined that the tire 100 has a leak, and the alarm module 3130 of the vehicle 1000 is controlled to issue an alarm.

[0143] In one embodiment, at time T(t), the tire pressure determination module 310 in the driving ECU receives the data F from the power detection module. T(t) 1(f T(t) 11 ,f T(t) 12 ,...,f T(t) 1n ), data F of terrain recognition module T(t) 2. Data F of the environmental detection module T (t) 3(f T(t) 31 ,f T(t) 32 ,...,f T(t) 3n ) and the data K of the driving mode recognition module 353.

[0144] The tire pressure determination module 310 calculates the required target tire pressure and target contact state as F T(t) (F T(t) 1,F T(t) 2,F T(t) 3,K), and judge F T(t) With F T(t-1) If they are the same, the state parameters and environmental parameters of the vehicle 1000 are received again; if they are different, the tire pressure determination module 310 determines the tire pressure according to F T(t) Calculate the required chamber pressure G of the multiple sub-chambers 111 of each tire 100 -1 (F T(t) ), the chamber pressure required by each sub-chamber 111 is recorded as G T(t) 11 ,G T(t) 12 ,G T(t) 13 ,...,G T(t) 1n ,G T(t) 21 ,G T(t) 22 ,G T(t) 23 ,...,G T(t) 2n ,G T(t) 31 ,G T(t) 32 ,G T(t) 33 ,...,G T(t) 3n ,G T(t) 41 ,G T(t) 42 ,G T(t) 43 ,...,G T(t) 4n ; The driving ECU sends the air pressure of each chamber to the air pressure control module 3110.

[0145] The air pressure detection module 390 records the air pressure data of each chamber of each wheel as P a1 ,P a2 ,P a3 ,...,P an ,P b1 ,P b2 ,P b3 ,...,P bn ,P c1 ,P c2 ,P c3 ,...,P cn ,P d1 ,P d2 ,P d3 ,...,P dn The air pressure control module 3110 receives data G T(t) ij , judge G T(t) ij With P T(t) ij When G T(t) ij >P T(t) ij When G T(t) ij <P T(t) ij When G T(t) ij =P T(t) ijWhen the tire pressure is set to zero, there is no need to inflate or deflate the tire. The ECU only needs to receive the status parameters and environmental parameters of the vehicle 1000 and determine a new target tire pressure.

[0146] When the charging and discharging time T of the electronically controlled charging valve 201 is T(t) ij ≤T k When P T(t) ij =G T(t) ij (i=a, b, c or d,,j=1, 2, ..., n), close the electronically controlled inflation and deflation valve 201, and the tire 100 is inflated and deflated;

[0147] On the contrary, the charging and discharging time T of the electronically controlled charging valve 201 is T(t) ij >T k , and P T(t) ij ≠G T(t) ij (i=a, b, c or d, j=1, 2, ..., n), the tire 100 is determined to be leaking, and an alarm signal is sent to the alarm module 3130. The alarm module 3130 receives the alarm signal, warns the user, and closes the cycle of the tire pressure control method.

[0148] See also Figure 10 An embodiment of the present application provides a tire 100, which includes an inflation / deflation module 330, and the inflation / deflation module 330 is configured to inflate and deflate the tire 100 based on the tire pressure control method of any of the above embodiments.

[0149] In some embodiments, the inflation and deflation module 330 includes an inflation and deflation component 331, an air storage component 333, an air distribution channel 335 and a rotatable component 337. The air storage component 333 is configured to inflate the tire 100 through the air distribution channel 335. The rotatable component 337 is arranged at the axis of the tire 100. The air distribution channel 335 includes a first channel 3351 and a second channel 3353. The first channel 3351 connects the inflation and deflation component 331 and the rotatable component 337, and the second channel 3353 connects the air storage component 333 and the rotatable component 337.

[0150] Specifically, the rotatable component 337 can be a rotatable bearing. The rotatable component 337 can be set at the center of the hub 103 of the tire 100. The rotatable component 337 includes a fixed end and a rotating end, and the rotating end can rotate relative to the fixed end. The first channel 3351 is connected to the rotating end of the rotatable bearing, and the second channel 3353 is connected to the fixed end of the rotatable bearing. When the tire 100 rotates, the second channel 3353 rotates with the tire 100, and the first channel 3351 does not rotate with it, so as to ensure that the connection between the air storage component 333 and the tire 100 is not affected when the tire 100 rotates. The second channel 3353, the rotatable component 337 and at least part of the first channel 3351 can form a "T-shaped" connection structure.

[0151] The gas storage assembly 333 includes a gas tank, a gas bottle, an gas bag, etc., which can be used to store gas to inflate the tire 100. The gas storage assembly 333 can inflate the tire 100 through the first channel 3351, the rotatable component 337, the second channel 3353 and the inflation and deflation assembly 331.

[0152] The inflation / deflation assembly 331 includes an electrically controlled inflation / deflation valve. The inflation / deflation assembly 331 can be disposed on the tire elastic body 101 and can connect the air distribution channel 335 with the inner cavity of the tire 100 so that the gas transmitted inside the air distribution channel 335 can be inflated into the inner cavity of the tire 100.

[0153] In this way, by setting the air distribution channel 335 in the form of a first channel 3351, a rotatable component 337 and a second channel 3353, the air storage component 333 can be kept connected to the inflation and deflation component 331 through the air distribution channel 335 when the tire 100 rotates.
