Description

Technical Field

[0001] The present application relates to the field of automotive technology, and in particular to a vehicle tire pressure control method, device, and equipment. Background Art

[0002] Tires are important basic components of a car and are also the components that come into contact with the ground during normal driving. The force generated by the engine is transmitted to the ground through the tires, providing thrust for the car to move forward. Therefore, the quality and safety of tires have a significant impact on the comfort and safety of the car.

[0003] Because tires are constantly in contact with the ground, they often come into contact with foreign objects, even sharp objects, during driving, causing a blowout. A blowout can significantly shift the vehicle's center of gravity, making it difficult for the driver to control the vehicle while driving, thus affecting driving safety. To address blowouts, a spare tire or tire sealant can be installed in the vehicle, allowing the user to manually replace or repair the tire after parking. Alternatively, a run-flat tire can be installed, allowing the vehicle to continue traveling at a reasonable speed for a longer distance after a blowout.

[0004] However, parking is inconvenient on highways, and a flat tire's impact on the vehicle's center of gravity can pose a safety hazard during parking. Therefore, relying on users to repair the problem themselves after parking presents challenges with timely response and driving safety. Furthermore, run-flat tires are expensive and relatively unavailable, so a flat tire while driving still poses a safety risk. Summary of the Invention

[0032] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0033] Tires are important basic components of automobiles. In order to absorb shock and support the vehicle, they are filled with high-pressure gas, and the tires are in constant contact with the ground during normal driving of the vehicle. Therefore, the quality of the tires affects the driving safety of the vehicle.

[0034] During driving, tires inevitably come into contact with foreign objects, even sharp ones, causing blowouts. A blowout can significantly shift the vehicle's center of gravity, making it difficult for the driver to control the vehicle and impacting driving safety. Therefore, reducing the incidence of blowouts or minimizing their impact on the vehicle can significantly improve driving safety.

[0035] A typical way to mitigate the impact of a tire blowout is to install run-flat tires. However, these are expensive and not widely available. Stopping to replace a spare tire or repair a tire has no positive impact on the vehicle's safety while driving. Therefore, a solution is needed to address the safety concerns of tire blowouts while driving.

[0036] In order to solve the above problems, the present application discloses a vehicle tire pressure control method, device and equipment, which detects the tire pressure data of the vehicle during driving, and promptly inflates and repairs tires with abnormal tire pressure or tire blowouts, thereby reducing the safety risks caused by tire blowouts during vehicle driving.

[0037] The following is an exemplary description of the file generation method disclosed in the embodiment of the present invention.

[0038] Figure 1 FIG. 1 is a flow chart showing a method for controlling tire pressure of a vehicle according to an embodiment of the present application. Figure 1 As shown, the method includes:

[0039] S110: During the driving of the vehicle, the tire pressure of the vehicle is detected to obtain first tire pressure data.

[0040] First, the vehicle's state must be determined, determining whether it is in motion or stationary. For example, the vehicle's speed can be obtained through a speed sensor. If the vehicle's speed is non-zero, the vehicle is considered to be in motion. When the vehicle is in motion, the tire pressure data can be tested to obtain first tire pressure data.

[0041] It should be noted that tire pressure can be monitored by tire pressure sensors respectively arranged on the vehicle wheel hub. Each tire has a corresponding tire pressure value. Therefore, in the embodiment of the present application, the first tire pressure data will include the tire pressure values ​​of all tires in the vehicle. Taking a family car as an example, the first tire pressure data will include the tire pressure values ​​of four tires, and each tire pressure value has a corresponding tire, so that the abnormal tire can be quickly found when the tire pressure value is abnormal.

[0042] S120: If the first tire pressure data is less than the first preset tire pressure, the status of the vehicle's air pump and the inflation valve connected to the air pump is detected.

[0043] After obtaining the first tire pressure data, the tire pressure values ​​corresponding to all tires in the first tire pressure data are compared with the first preset tire pressure. If there is a tire in the first tire pressure data with a tire pressure value less than the first preset tire pressure, it means that the tire pressure of the tire is abnormal. There are many reasons for abnormal tire pressure, such as cracks, tire blowouts, etc.

[0044] In some embodiments, when detecting tire pressure, the rate of change of tire pressure can also be detected. The rate of change of tire pressure can be described by the ratio of the tire pressure at the starting time point to the tire pressure at the end time point in a certain time period. When the rate of change of tire pressure is too large, it is considered that the tire pressure of the tire is abnormal.

[0045] It should be understood that the normal tire pressure of a vehicle during driving should be within a numerical range. That is, when the tire pressure value is within the numerical range, the vehicle's tire pressure data is normal. Based on this, whether the vehicle's tire pressure is greater than the maximum value in the numerical range or less than the minimum value in the numerical range, it will pose a risk to driving safety. The first preset tire pressure can be the minimum value in the numerical range to improve the sensitivity of inflation. However, in the embodiment of the present application, except that the first preset tire pressure needs to be less than the maximum value of the numerical range, there is no restriction on the first preset tire pressure. The first preset tire pressure can be less than the minimum value in the numerical range. For example, the first preset tire pressure can be half of the minimum value in the numerical range.

[0046] In addition, since the ranges of normal tire pressures for tires at different locations may be different, in some embodiments of the present application, the first preset tire pressure may also include preset tire pressure values ​​corresponding to the number of tires of the vehicle.

[0047] When the first tire pressure data is detected to contain a tire with a pressure value less than a first preset pressure, it is considered that the first tire pressure data is less than the first preset pressure, and the status of the vehicle's inflation valve is then detected. For example, in a family car, there are four inflation valves, each corresponding to one of the four tires. When the obtained tire pressure data is less than the first preset pressure, the status of the inflation valve in the corresponding tire is detected based on the tire corresponding to the tire pressure data. It should be understood that the number of inflation valves in each tire may not be unique, and this application does not impose any restrictions on the number of inflation valves.

[0048] S130: If the air pump and the inflation valve are both in the closed state, the air pump and the inflation valve are controlled to open, so as to control the air pump to inflate the tire of the vehicle through the inflation valve.

[0049] When the vehicle's air pump and inflation valve are detected to be closed, the corresponding tire's inflation valve is controlled to open, and the vehicle's air pump is simultaneously turned on to inflate the vehicle's tire. For example, when detecting valve status, only the inflation valve in the tire with abnormal tire pressure is tested, thereby preventing the inflation valve from opening incorrectly and causing air to be inflated into the tire with normal tire pressure, leading to excessive tire pressure.

[0050] It should be understood that the inflation valve needs to be connected to a device with gas generation or gas delivery functions in order to achieve the operation of replenishing air for the vehicle's tires while the vehicle is driving. Therefore, an air pump needs to be installed in the vehicle to pump air into the tires. For example, in an embodiment of the present application, in order to save internal space of the vehicle, the inflation valves of all tires can be connected to an air pump through a pipeline. The air pump can provide gas for replenishing air to the tires through the pipeline. Specifically, the air pump can compress external air and pump high-pressure gas into the tires, thereby increasing or maintaining the tire pressure of the tire with a tire pressure failure.

[0051] In some embodiments, the vehicle can simultaneously control the opening and closing of the air pump and the inflation valve, or a detection module can be set in the air pump. When the air pump detects that the inflation valve is opened, it automatically performs the inflation operation without issuing a control instruction.

[0052] Through the above technical solution, when the tire pressure of the vehicle's tire is abnormal, air can be filled into the tire, thereby ensuring that the tire pressure is not too low to affect the center of gravity of the vehicle and cause safety risks.

[0053] Figure 2 A flow chart of another vehicle tire pressure control method according to an embodiment of the present application is shown. In some cases, such as when a tire blows out or a large crack appears on the tire, a simple inflation operation is not enough to increase the tire pressure or even the inflation operation cannot maintain the tire pressure of the faulty tire. Therefore, in some embodiments, such as Figure 2 As shown, the method further includes:

[0054] S210: During the driving of the vehicle, the tire pressure of the vehicle is detected to obtain first tire pressure data.

[0055] S220: If the first tire pressure data is less than the first preset tire pressure, the status of the vehicle's air pump and the inflation valve connected to the air pump is detected.

[0056] S230: If the air pump and the inflation valve of the vehicle are both in the closed state, the air pump of the vehicle and the inflation valve connected to the air pump are controlled to open, so as to control the air pump to inflate the tire of the vehicle through the inflation valve.

[0057] The execution process of steps S210 to S230 in the method is the same as the execution process of steps S110 to S130 mentioned above, so steps S210 to S230 will not be described in detail in this application.

[0058] S240: Detecting the status of the glue valve connected to the fluid storage tank of the vehicle.

[0059] When the first tire pressure data is less than the first preset tire pressure, the status of the tire's glue valve can also be detected. Specifically, similar to the inflation valve, the glue valve is also installed in different tires. To deliver sealant fluid to the tire to fill cracks, the glue valve needs to be connected to a reservoir storing the sealant fluid. It should be noted that a tire can be equipped with one or more glue valves, and this application does not limit the number of glue valves in each tire.

[0060] In addition, the inflation valve and the glue valve can be arranged on the wheel hub or the rim, and are respectively connected to the air pump and the liquid storage tank through pipelines.

[0061] S250: If the glue valve is in the closed state, the glue valve is controlled to open, so as to control the tire repair fluid in the fluid storage tank to repair the tire of the vehicle.

[0062] When the glue valve of a vehicle is detected to be closed, the glue valve in the corresponding tire is controlled to open, thereby repairing the vehicle's tire with tire sealant. For example, when detecting the valve status, only the glue valve in the tire with abnormal tire pressure is tested, thereby preventing the glue valve from being opened incorrectly and causing tire sealant to flow into the tire with normal tire pressure, thereby wasting tire sealant.

[0063] In some embodiments of the present application, in order to ensure that the tire repair fluid in the liquid storage tank can be quickly released into the faulty tire, the liquid storage tank can be connected to the air pump through a pressure valve. When the glue valve is opened, the pressure valve can be opened synchronously, so that the gas generated by the air pump can be pumped into the liquid storage tank, increasing the air pressure in the liquid storage tank, so that the tire repair fluid stored in the liquid storage tank is transported to the faulty tire through the pipeline and the glue valve, thereby achieving the purpose of repairing the tire with the tire repair fluid.

[0064] When the glue valve is opened, the tire repair fluid can be delivered to the tire with abnormal tire pressure. If there is an air leak in the tire, the tire repair fluid will fill the gap in the tire under the action of air pressure, thereby achieving the purpose of repairing the tire.

[0065] It should be noted that there is no strict order for executing steps S220-S230 and steps S240-S250, that is, the status of the glue valve can be detected first and the glue valve can be opened, or the status of the inflation valve can be detected first and the inflation valve can be opened, or the status can be detected at the same time and opened at the same time. In the embodiment of the present application, there is no restriction on the operating sequence of the detection of the glue valve and the inflation valve. The above steps S220-S230 and S240-S250 are only a possible implementation scenario.

[0066] In some embodiments of the present application, the switching status of the air pump, inflation valve and glue valve can also be manually switched by the user in the vehicle. For example, when the tire pressure of the vehicle is abnormal, the information about the abnormal tire pressure is conveyed to the user in the form of images, videos or audio through the vehicle's on-board screen, voice components, etc. At this time, the user can input commands to open the air pump, inflation valve and glue valve through voice, buttons or icon controls on the vehicle screen, thereby controlling the opening of the air pump, inflation valve and glue valve to achieve manual control.

[0067] Similarly, when the vehicle's tire pressure returns to the normal range, the information that the vehicle's tire pressure has recovered is conveyed to the user in the form of images, videos or audio through the vehicle's on-board screen, voice components, etc. The user can again input commands to close the air pump, inflation valve and glue valve through voice, buttons or icon controls on the vehicle's screen, thereby controlling the closure of the air pump, inflation valve and glue valve.

[0068] It should be understood that in order to avoid excessive tire pressure due to inflation when the vehicle's tire pressure is normal, the user-input instructions for controlling the opening of the air pump, inflation valve and glue valve will only be executed by the vehicle when the vehicle's tire pressure is low.

[0069] Through the above technical solution, when the tire pressure of a vehicle's tire becomes abnormal, gas can be added to the tire while the tire is repaired with tire repair fluid, so that the inflation operation can maintain or increase the tire pressure, thereby ensuring that the tire pressure is not too low to affect the center of gravity of the vehicle and cause safety risks.

[0070] Figure 3 A flow chart of another vehicle tire pressure control method according to an embodiment of the present application is shown. In some cases, after the tire pressure reaches a normal range or a preset value, it is necessary to stop filling the tire to prevent energy waste. Therefore, in some embodiments, such as Figure 3 As shown, the method further includes:

[0071] S310: While the vehicle is traveling, the tire pressure of the vehicle is detected to obtain first tire pressure data.

[0072] S320: If the first tire pressure data is less than the first preset tire pressure, the status of the vehicle's air pump, inflation valve, and glue valve are detected.

[0073] S330: If the air pump, the inflation valve, and the glue valve are all in the closed state, the air pump, the inflation valve, and the glue valve are controlled to open to inflate and repair the tire of the vehicle.

[0074] The execution process of steps S310 to S330 in the method is the same as the execution process of steps S210 to S250 mentioned above, so steps S310 to S330 will not be described in detail in this application.

[0075] S340: Detecting second tire pressure data of the vehicle.

[0076] When performing the tire inflation and tire repair operations, the tire pressure data of the vehicle is continuously detected to obtain second tire pressure data. The second tire pressure data may also be the same as the first tire pressure data, including tire pressure data of all tires of the vehicle.

[0077] In some embodiments, the second tire pressure data may only be collected for the tire undergoing inflation or repair. If the collected second tire pressure data is less than the second preset tire pressure, it indicates that the tire is not fully inflated or repaired, and further inflation or repair is required until the second tire pressure data exceeds the second preset tire pressure.

[0078] S350: If the second tire pressure data is greater than the second preset tire pressure, determine the status of the air pump and the inflation valve.

[0079] The second preset tire pressure is greater than or equal to the first preset tire pressure, and is less than the maximum value in the normal tire pressure range of the vehicle tire. The specific value of the second preset tire pressure is not limited in the embodiment of the present application.

[0080] When it is detected that the second tire pressure data is greater than the second preset tire pressure, the state of the vehicle's inflation valve is detected.

[0081] S360: If the air pump and the inflation valve are both in the open state, control the air pump and the inflation valve to be closed.

[0082] When it is detected that the vehicle's air pump and inflation valve are in the open state, the vehicle's air pump and inflation valve are controlled to be closed, thereby avoiding overinflation that causes the tire pressure to be too high.

[0083] S370: Determine the status of the glue valve of the vehicle.

[0084] Similar to the above S350, when it is detected that the second tire pressure data is greater than the second preset tire pressure, the state of the glue valve of the vehicle needs to be detected. If the glue valve is in the closed state, no processing is performed.

[0085] S380: If the glue valve is in the open state, control the glue valve to close.

[0086] If the glue valve of the vehicle is in an open state, the glue valve of the vehicle is controlled to be closed, thereby saving tire sealant fluid and avoiding the situation where there is no tire sealant fluid available in the storage tank when tire pressure in other tires is abnormal due to tire sealant waste.

[0087] It should be noted that in some embodiments, if the liquid storage tank is connected to the air pump through a pressure valve, when the glue valve is closed, the pressure valve also needs to be closed synchronously to avoid excessive pressure in the liquid storage tank and damage to the liquid storage tank or pipeline.

[0088] In addition, there is no strict order for executing the above-mentioned steps S350-S360 and steps S370-S380, that is, the status of the glue valve can be detected first and the glue valve can be closed, or the status of the inflation valve can be detected first and the inflation valve can be closed, or the status can be detected at the same time and closed at the same time. In the embodiment of the present application, there is no restriction on the operation sequence of detecting the glue valve and the inflation valve. The above-mentioned steps S350-S360 and steps S370-S380 are only a possible implementation scenario.

[0089] Through the above technical solution, after the tire pressure of the vehicle tire becomes abnormal and returns to normal after air filling and tire repair, the inflation valve and glue valve can be closed to avoid overinflation causing excessive tire pressure and save the use of tire repair fluid.

[0090] Figure 4 A flow chart of another vehicle tire pressure control method according to an embodiment of the present application is shown. In some cases, after the tire pressure reaches a normal range or a preset value, it is necessary to stop filling the tire to prevent energy waste. Therefore, in some embodiments, such as Figure 4 As shown, the method further includes:

[0091] S410: During the driving of the vehicle, the tire pressure of the vehicle is detected to obtain first tire pressure data.

[0092] S420: If the first tire pressure data is less than the first preset tire pressure, the status of the vehicle's air pump, inflation valve, and glue valve are detected.

[0093] S430: If the air pump, the inflation valve, and the glue valve are all in the closed state, the air pump, the inflation valve, and the glue valve are controlled to open to inflate and repair the tire of the vehicle.

[0094] S440: Detecting the second tire pressure data of the vehicle.

[0095] S450: If the second tire pressure data is greater than the second preset tire pressure, the states of the air pump, the inflation valve, and the glue valve are determined.

[0096] S460: If the air pump, the inflation valve, and the glue valve are all in the open state, the air pump, the inflation valve, and the glue valve are controlled to be closed.

[0097] The execution process of steps S410 to S460 in the method is the same as the execution process of steps S310 to S380 mentioned above, so steps S410 to S460 will not be described in detail in this application.

[0098] S470: Detect the amount of tire sealant in the fluid storage tank.

[0099] After closing the glue valve, the amount of tire sealant in the liquid storage tank connected to the glue valve is detected. By detecting the amount of tire sealant, it is possible to determine how much tire sealant has been used for this tire repair and how much tire sealant is left. When the tire sealant is too low, the user can be reminded to refill it.

[0100] In some embodiments, for example, a meter for displaying the level of tire sealant fluid may be provided on the dashboard of the vehicle, thereby displaying the level of tire sealant fluid in the reservoir in real time. On this basis, a sensor may be provided in the reservoir to monitor the level of tire sealant fluid in the reservoir in real time, so that the user can know the level of tire sealant fluid at any time.

[0101] S480: If the amount of tire sealant is less than a preset amount, generate and output an amount prompt message.

[0102] The remaining level reminder is used to inform the user that the vehicle's tire sealant level is low. For example, the preset level can be 20% of the tank's upper capacity. That is, when the glue valve is closed and the remaining level of tire sealant in the tank is less than 20% of the upper capacity, the vehicle will generate a remaining level reminder. This remaining level reminder, similar to the recovery reminder described in the following steps, can be displayed on the vehicle's screen, through voice interaction, or output to the user's terminal device associated with the vehicle.

[0103] S490: Generate and output recovery prompt information.

[0104] The recovery prompt message is used to inform the user that the vehicle's tire pressure has returned to normal. After the reply prompt message is generated, the vehicle needs to be controlled to send the reply prompt message to the user. For example, the recovery prompt message can be displayed on the vehicle's on-board screen, or sent to a terminal device associated with the vehicle via a remote connection such as a cloud server or the Internet, or played via an in-vehicle voice message.

[0105] It should be noted that there is no strict order in which the above steps S470-S480 and step S490 are to be executed. The recovery prompt information can be generated first, or the amount of tire repair fluid in the storage tank can be checked first. The above steps S470-S480 and step S490 are only one possible implementation method.

[0106] Through the above technical solution, when the tire pressure of a vehicle tire becomes abnormal and returns to normal after air filling and tire repair, the user can be prompted that the tire pressure has returned to normal and the user can be reminded to replenish the tire repair fluid when it is too low.

[0107] Figure 5A flow chart of another vehicle tire pressure control method in an embodiment of the present application is shown. In some cases, when the tire pressure is abnormal, it is necessary to notify the user so that the user can know the situation in time and perform subsequent processing. Therefore, in some embodiments, such as Figure 5 As shown, the method further includes:

[0108] S510: While the vehicle is traveling, the tire pressure of the vehicle is detected to obtain first tire pressure data.

[0109] S520: If the first tire pressure data is less than the first preset tire pressure, the status of the vehicle's air pump and the inflation valve connected to the air pump is detected.

[0110] S530: If the air pump and the inflation valve are both in the closed state, the air pump and the inflation valve are controlled to open, so as to control the air pump to inflate the tire of the vehicle through the inflation valve.

[0111] The execution process of steps S510 to S530 in the method is the same as the execution process of steps S110 to S130 mentioned above, so steps S510 to S530 will not be described in detail in this application.

[0112] S540: Generate and output alarm information.

[0113] The warning message is used to inform the user that the tire pressure of a certain tire of the vehicle is abnormal. After the warning message is generated, it is necessary to control the vehicle to output the warning message to the user to achieve the effect of reminding. For example, the warning message can be displayed on the vehicle's on-board screen, or sent to a terminal device associated with the vehicle through a remote connection method such as a cloud server or the Internet, or the warning message can be played through the vehicle's voice.

[0114] Through the above technical solution, the user can be notified in time when the tire pressure of the vehicle is abnormal, which is convenient for the user to discover and perform subsequent processing.

[0115] Based on the above vehicle tire pressure control method, this application also provides a vehicle tire pressure control device 600, such as Figure 6 Shown, including:

[0116] The tire pressure monitoring component 610 is used to detect the tire pressure of the vehicle during the vehicle's driving process and obtain first tire pressure data;

[0117] a valve monitoring component 620 for detecting a status of an air pump of the vehicle and an inflation valve connected to the air pump if the first tire pressure data is less than a first preset tire pressure;

[0118] The controller 630 is used to control the vehicle's inflation valve to open when the air pump and the inflation valve are both in the closed state, so as to control the air pump to inflate the vehicle's tires through the inflation valve.

[0119] The air pump 640 is connected to the inflation valve and is used to generate gas to inflate the tires of the vehicle.

[0120] In an optional embodiment, the vehicle tire pressure control device 600 also includes: a liquid storage tank, one end of the liquid storage tank is connected to the glue valve of the vehicle, and the other end of the liquid storage tank is connected to the air pump through a pressure valve. The liquid storage tank is used to store tire repair fluid and release the tire repair fluid into the vehicle's tire through the glue valve through the air pressure generated by the air pump.

[0121] In an optional embodiment, the valve monitoring component 620 and the controller 630 are also used to: detect the status of the glue valve connected to the vehicle's fluid storage tank; if the status of the vehicle's glue valve is closed, control the vehicle's glue valve to open, so as to control the tire repair fluid in the fluid storage tank to repair the vehicle's tires.

[0122] In an optional manner, after controlling the vehicle's inflation valve to open, the vehicle tire pressure control device 600 is also used to: detect the vehicle's second tire pressure data; if the second tire pressure data is greater than the second preset tire pressure, determine the status of the air pump and the inflation valve; the second preset tire pressure is greater than or equal to the first preset tire pressure; if the status of the air pump and the inflation valve are both open, control the air pump and the inflation valve to close.

[0123] In an optional manner, the valve monitoring component 620 and the controller 630 are further configured to: determine the state of the glue valve of the vehicle; and if the state of the glue valve of the vehicle is open, control the glue valve of the vehicle to close.

[0124] In an optional embodiment, the vehicle tire pressure control device 600 is also used to: detect the amount of tire sealant fluid in a liquid storage tank connected to the glue valve; if the amount of tire sealant fluid is less than a preset amount, generate a stock prompt message, and the stock prompt message is used to prompt the user that the amount of tire sealant fluid in the vehicle is insufficient.

[0125] In an optional manner, the controller 630 is further configured to: generate an alarm message if the first tire pressure data is less than a first preset tire pressure, the alarm message being used to remind the user that the tire pressure of the vehicle is abnormal; and output the alarm message.

[0126] In an optional manner, the controller 630 is further used to: generate a recovery prompt message if the second tire pressure data is greater than the second preset tire pressure, the recovery prompt message being used to prompt the user that the tire pressure of the vehicle has returned to normal; and output the recovery prompt message.

[0127] In some embodiments, the controller 630 is also configured to receive user commands, including commands for controlling the on / off status of components such as the air pump, inflation valve, and glue valve, and to evaluate these commands. For example, if the air pump, inflation valve, or glue valve is open, the controller 630 will only execute the corresponding command when the vehicle's tire pressure is low. Furthermore, the controller 630 can monitor information such as the vehicle's tire pressure, the valve status of the device, and the level of tire sealant via the tire pressure monitoring component 610, the valve monitoring component 620, and various sensors, and transmit this information to the vehicle's onboard screen or dashboard to inform the user of the device's status, allowing the user to understand the vehicle's overall condition.
