[0027] In this embodiment, a method for determining vehicle tire pressure running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0028] Figure 2 FIG. 1 is a flow chart of a method for determining vehicle tire pressure according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0029] Step S201, obtaining reference data of the wheels, the reference data of the wheels including reference tire pressure values ​​of the wheels and reference rotation numbers of the wheels corresponding to each reference tire pressure value, the reference rotation numbers of the wheels being the number of rotations of the wheels per predetermined kilometer of straight-line travel when the tire pressure value of the wheels is the reference tire pressure value;

[0030] Specifically, the above-mentioned benchmark data can be obtained through multiple tests when the vehicle leaves the factory, or can be the historical data of other vehicles of the same model obtained by the background. For example, some vehicles can set a fixed tire pressure value when driving. The owner will set the above-mentioned fixed tire pressure value during a certain driving, and the background will collect the number of rotations of the wheel under the fixed tire pressure value and record it as a set of benchmark data. The background will collect multiple sets of such data to obtain a benchmark data table for subsequent comparison with the real-time number of rotations of the wheel;

[0031] The predetermined kilometer can be 1 kilometer, 0.5 kilometer, 2 kilometers, etc., and is generally set to 1 kilometer.

[0032] Step S202, obtaining the real-time rotation number of the wheel in real time, where the real-time rotation number of the wheel is the actual rotation number of the vehicle when the vehicle travels a predetermined number of kilometers in a straight line;

[0033] Specifically, the wheels include one of the left front wheel, the right front wheel, the left rear wheel, and the right rear wheel. Since the inner circle radius is not the same as the outer circle radius when the vehicle is traveling on a curve, it is more complicated to calculate the distance, thereby increasing the calculation process of the real-time number of rotations. Therefore, directly obtaining the number of rotations of the wheels when the vehicle is traveling in a straight line can simplify the calculation process, improve efficiency and reduce costs.

[0034] The specific implementation steps of step S202 are as follows:

[0035] Step S2021, obtaining the cumulative mileage of the vehicle, where the cumulative mileage is the cumulative mileage of the vehicle when it travels in a straight line within a predetermined time;

[0036] Step S2022, obtaining the total number of rotations of the wheel, where the total number of rotations of the wheel is the total number of rotations of the wheel when the vehicle travels the accumulated mileage in a straight line;

[0037] Step S2023, determining the real-time number of rotations of the wheels according to the accumulated mileage and the total number of rotations of the wheels, wherein the real-time number of rotations of the wheels is the ratio of the total number of rotations of the wheels to the accumulated mileage.

[0038] As can be seen from the above, since the calculation of the distance traveled on a curve and the number of rotations of each tire is relatively complicated, the mileage of the vehicle when it is traveling in a straight line is generally directly obtained as the cumulative mileage, and the real-time number of rotations obtained in the above embodiment is the number of rotations of the wheel for every kilometer of straight-line driving. Correspondingly, in other embodiments, the number of rotations of the wheel for every other number of kilometers of straight-line driving (for example: two kilometers, three kilometers, etc.) can also be used as the real-time number of rotations, and the subsequent calculation process is also adjusted accordingly. In other schemes, the distance traveled on a curve can also be counted into the cumulative mileage, and the subsequent calculation process can be adjusted accordingly.

[0039] like Figure 3 As shown, the cumulative mileage is the cumulative mileage when the vehicle travels in a straight line within a predetermined time, that is, the cumulative mileage [D] = D1 + D2 + D3 + ... + Dn. The number of kilometers traveled by the vehicle in a straight line is directly obtained as the cumulative mileage, and the number of wheel rotations per kilometer can simplify the calculation process, improve efficiency and reduce costs.

[0040] Step S203, compare the real-time rotation number of the above-mentioned wheels with the reference rotation number of the above-mentioned wheels to obtain a comparison result; and determine the current tire pressure value of the above-mentioned wheels at least based on the above-mentioned comparison result, and the above-mentioned comparison result includes whether the real-time rotation number of the above-mentioned wheels is the same as the reference rotation number of each of the above-mentioned wheels.

[0041] Specifically, since the current tire pressure value corresponding to each real-time number of rotations is different, and the benchmark data may not be able to accurately obtain the tire pressure value corresponding to each number of rotations (that is, the benchmark data may only be two groups), it is necessary to first compare the real-time number of rotations with the benchmark number of rotations recorded in the benchmark data. If a benchmark number of rotations in the benchmark data is exactly the same as the real-time number of rotations, the benchmark tire pressure value corresponding to the benchmark number of rotations can be directly determined as the current tire pressure value. If there is no benchmark number of rotations in the benchmark data that is the same as the real-time number of rotations, the corresponding current tire pressure value will be obtained through subsequent calculation.

[0042] In one embodiment, the real-time rotation number of the wheel is compared with the reference rotation number of the plurality of wheels to obtain a comparison result; and the current tire pressure value of the wheel is determined at least based on the comparison result, including: when the real-time rotation number of the wheel is the same as the reference rotation number of one of the wheels, the reference tire pressure value corresponding to the reference rotation number of the wheel is determined as the current tire pressure value of the wheel. In this way, the current tire pressure value can be determined directly without going through the calculation process, simplifying the calculation steps and reducing the cost.

[0043] Specifically, when the real-time number of rotations of the wheel is the same as the reference number of rotations of one of the wheels, there is no need to perform further calculation steps, and the reference tire pressure value corresponding to the reference number of rotations can be directly determined as the current tire pressure value.

[0044] In another embodiment, the real-time rotation number of the wheel is compared with the reference rotation number of the plurality of wheels to obtain a comparison result; and the current tire pressure value of the wheel is determined at least based on the comparison result, including: when the real-time rotation number of the wheel is different from the reference rotation number of each wheel, the current tire pressure value of the wheel is determined based on the reference rotation number of at least some of the wheels, the reference tire pressure value of the wheel corresponding to at least some of the reference rotation numbers, the standard tire pressure value of the wheel, the standard rotation number of the wheel corresponding to the standard tire pressure value, and the real-time rotation number of the wheel; wherein the standard tire pressure value is the tire pressure value set when the vehicle leaves the factory, and the standard rotation number is the number of rotations of the wheel when the vehicle has the tire pressure value of the wheel being the standard tire pressure value per predetermined kilometer of straight-line travel. In this way, the current tire pressure value can be obtained more accurately.

[0045] Specifically, depending on the wheel model or the vehicle model, the corresponding standard tire pressure value is also different. Generally, the predetermined kilometer can be set to one kilometer, which can facilitate the overall calculation, and the reference rotation circle of at least some of the above wheels can be two, three, etc., and the calculation process can be adjusted accordingly according to the different numbers.

[0046] Wherein, in the case where the real-time number of rotations of the wheels is different from the reference number of rotations of each of the wheels, the specific implementation steps of determining the current tire pressure value of the wheels according to the reference number of rotations of at least some of the wheels, the reference tire pressure values ​​of the wheels corresponding to at least some of the reference number of rotations, the standard tire pressure values ​​of the wheels, the standard number of rotations of the wheels corresponding to the standard tire pressure values, and the real-time number of rotations of the wheels are as follows:

[0047] Step S301, obtaining the reference rotation numbers of the two wheels, and obtaining the two reference tire pressure values ​​corresponding to the two reference rotation numbers respectively;

[0048] Step S302, determining a unit tire pressure calibration amount according to the two reference rotation numbers and the two reference tire pressure values ​​respectively corresponding to the two reference rotation numbers, wherein the unit tire pressure calibration amount is a ratio of a difference between the two reference tire pressure values ​​respectively corresponding to the two reference rotation numbers and a difference between the two reference rotation numbers;

[0049] Step S303, determining the current tire pressure value of the wheel according to the standard tire pressure value of the wheel, the standard number of rotations of the wheel corresponding to the standard tire pressure value, the real-time number of rotations of the wheel and the unit tire pressure calibration amount.

[0050] Specifically, the unit tire pressure correction amount is the tire pressure value that differs for each additional (or less) rotation of the wheel. The firstly obtained unit tire pressure correction amount is the basis for the subsequent calculation of the current tire pressure value, and the accurate current tire pressure value can be obtained.

[0051] The specific implementation steps of step S303 are as follows:

[0052] Step S3031, obtaining a rotation number difference, where the rotation number difference is the difference between the real-time rotation number of the wheel and the standard rotation number of the wheel;

[0053] Step S3032, when the lap number difference is greater than zero, the difference between the standard tire pressure value of the wheel and the actual tire pressure correction amount is determined as the current tire pressure value of the wheel, and the actual tire pressure correction amount is the product of the lap number difference and the unit tire pressure calibration amount. The current tire pressure value can be determined more accurately without installing a tire pressure sensor, and the calculation process is simple and the cost is low.

[0054] Specifically, the circle number difference represents the difference between the real-time number of rotations of the wheel and the standard number of rotations of the wheel. Multiplying it by the unit tire pressure calibration value can give the difference between the current tire pressure value and the standard tire pressure value. Finally, the standard tire pressure value is added or subtracted from the difference between the current tire pressure value and the standard tire pressure value to get the current tire pressure value.

[0055] Among them, when the difference in the number of revolutions is greater than zero, it means that the real-time number of revolutions is greater than the standard number of revolutions, which means that the diameter of the wheel at the current moment is smaller than the standard wheel diameter, proving that the current tire pressure value is smaller than the standard tire pressure value, so the current tire pressure value should be the value obtained by subtracting the above difference from the standard tire pressure value.

[0056] In one embodiment, step S303 further includes the following steps:

[0057] Step S3033, when the circle number difference is less than zero, the sum of the standard tire pressure value of the wheel and the actual tire pressure correction amount is determined as the current tire pressure value of the wheel, wherein the actual tire pressure correction amount is the product of the circle number difference and the unit tire pressure calibration amount, and the circle number difference is the difference between the real-time rotation circle number of the wheel and the standard rotation circle number of the wheel;

[0058] Step S3034: when the lap difference is zero, the standard tire pressure value of the wheel is determined as the current tire pressure value of the wheel. The current tire pressure value can be determined more accurately without installing a tire pressure sensor, thereby reducing the cost of installing a tire pressure sensor.

[0059] Among them, when the difference in the number of revolutions is less than zero, it means that the real-time number of revolutions is less than the standard number of revolutions, which means that the diameter of the wheel at the current moment is greater than the standard wheel diameter, proving that the current tire pressure value is greater than the standard tire pressure value, so the current tire pressure value should be the value obtained by adding the standard tire pressure value to the above difference.

[0060] When the difference in the number of revolutions is equal to zero, it means that the real-time number of revolutions is equal to the standard number of revolutions, which means that the diameter of the wheel at the current moment is equal to the standard wheel diameter, proving that the current tire pressure value is equal to the standard tire pressure value, so the current tire pressure value is the standard tire pressure value.

[0061] Wherein, at least according to the comparison result, determining the current tire pressure value of the wheel further comprises the following steps:

[0062] Step S401, determining an initial tire pressure value according to the real-time rotation number of the wheel and the historical data of the wheel;

[0063] Step S401, obtaining an influencing factor, where the influencing factor is at least related to one of a road condition information factor, a temperature information factor and a humidity information factor;

[0064] Step S401: Use the influencing factor to correct the initial tire pressure value to obtain the current tire pressure value of the wheel.

[0065] Specifically, under different environmental conditions, the wheels may experience thermal expansion and contraction, resulting in inaccurate calculation of tire pressure and lap values. In this case, it is necessary to introduce influencing factors during the calculation to avoid the impact of the environment on the current tire pressure calculation results, making the current tire pressure calculation more accurate.

[0066] The method for determining the tire pressure of a vehicle of the present application first obtains the reference data of the wheel, the reference data of the wheel includes the reference tire pressure values ​​of multiple wheels and the reference rotation number of the wheel corresponding to each reference tire pressure value, the reference rotation number of the wheel is the number of rotations of the wheel for each predetermined kilometer of straight-line driving when the tire pressure value of the wheel is the reference tire pressure value; then obtains the real-time rotation number of the wheel in real time, the real-time rotation number of the wheel is the actual number of rotations of the vehicle when the vehicle travels the predetermined kilometer in a straight line; finally compares the real-time rotation number of the wheel with the reference rotation number of multiple wheels to obtain a comparison result; and determines the current tire pressure value of the wheel at least based on the comparison result, the comparison result includes whether the real-time rotation number of the wheel is the same as the reference rotation number of each wheel. The method can also monitor the tire pressure of the vehicle in real time without installing a tire pressure sensor, ensures the driving safety of the vehicle, reduces the cost, and solves the problem that the existing technology relies on the tire pressure sensor to monitor the tire pressure in real time, has the risk of failure and is high in cost.

[0080] The processor includes a kernel, which retrieves the corresponding program unit from the memory. One or more kernels can be set, and the kernel parameters can be adjusted to solve the problem that the existing technology relies on tire pressure sensors to monitor tire pressure in real time, which has the risk of failure and high cost.

[0081] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.

[0082] An embodiment of the present invention provides a computer-readable storage medium, which includes a stored program, wherein when the program is executed, the device where the computer-readable storage medium is located is controlled to execute the method for determining the vehicle tire pressure.

[0083] Specifically, the method for determining the vehicle tire pressure includes:

[0084] Step S201, obtaining reference data of the wheels, the reference data of the wheels including reference tire pressure values ​​of the wheels and reference rotation numbers of the wheels corresponding to each reference tire pressure value, the reference rotation numbers of the wheels being the number of rotations of the wheels per predetermined kilometer of straight-line travel when the tire pressure value of the wheels is the reference tire pressure value;

[0085] Specifically, the above-mentioned benchmark data can be obtained through multiple tests when the vehicle leaves the factory, or can be the historical data of other vehicles of the same model obtained by the background. For example, some vehicles can set a fixed tire pressure value when driving. The owner will set the above-mentioned fixed tire pressure value during a certain driving, and the background will collect the number of rotations of the wheel under the fixed tire pressure value and record it as a set of benchmark data. The background will collect multiple sets of such data to obtain a benchmark data table for subsequent comparison with the real-time number of rotations of the wheel;

[0086] Step S202, obtaining the real-time rotation number of the wheel in real time, where the real-time rotation number of the wheel is the actual rotation number of the vehicle when the vehicle travels a predetermined number of kilometers in a straight line;

[0087] Specifically, the wheels include one of the left front wheel, the right front wheel, the left rear wheel, and the right rear wheel. Since the inner circle radius is not the same as the outer circle radius when the vehicle is traveling on a curve, it is more complicated to calculate the distance, thereby increasing the calculation process of the real-time number of rotations. Therefore, directly obtaining the number of rotations of the wheels when the vehicle is traveling in a straight line can simplify the calculation process, improve efficiency and reduce costs.

[0088] Step S203, compare the real-time rotation number of the above-mentioned wheels with the reference rotation number of the above-mentioned wheels to obtain a comparison result; and determine the current tire pressure value of the above-mentioned wheels at least based on the above-mentioned comparison result, and the above-mentioned comparison result includes whether the real-time rotation number of the above-mentioned wheels is the same as the reference rotation number of each of the above-mentioned wheels.

[0089] Specifically, since the current tire pressure value corresponding to each real-time number of rotations is different, and the benchmark data may not be able to accurately obtain the tire pressure value corresponding to each number of rotations (that is, the benchmark data may only be two groups), it is necessary to first compare the real-time number of rotations with the benchmark number of rotations recorded in the benchmark data. If a benchmark number of rotations in the benchmark data is exactly the same as the real-time number of rotations, the benchmark tire pressure value corresponding to the benchmark number of rotations can be directly determined as the current tire pressure value. If there is no benchmark number of rotations in the benchmark data that is the same as the real-time number of rotations, the corresponding current tire pressure value will be obtained through subsequent calculation.

[0090] An embodiment of the present invention provides a processor, and the processor is used to run a program, wherein the method for determining the vehicle tire pressure is executed when the program is run.

[0091] Specifically, the method for determining the vehicle tire pressure includes:

[0092] Step S201, obtaining reference data of the wheels, the reference data of the wheels including reference tire pressure values ​​of the wheels and reference rotation numbers of the wheels corresponding to each reference tire pressure value, the reference rotation numbers of the wheels being the number of rotations of the wheels per predetermined kilometer of straight-line travel when the tire pressure value of the wheels is the reference tire pressure value;

[0093] Specifically, the above-mentioned benchmark data can be obtained through multiple tests when the vehicle leaves the factory, or can be the historical data of other vehicles of the same model obtained by the background. For example, some vehicles can set a fixed tire pressure value when driving. The owner will set the above-mentioned fixed tire pressure value during a certain driving, and the background will collect the number of rotations of the wheel under the fixed tire pressure value and record it as a set of benchmark data. The background will collect multiple sets of such data to obtain a benchmark data table for subsequent comparison with the real-time number of rotations of the wheel;

[0094] Step S202, obtaining the real-time rotation number of the wheel in real time, where the real-time rotation number of the wheel is the actual rotation number of the vehicle when the vehicle travels a predetermined number of kilometers in a straight line;

[0095] Specifically, the wheels include one of the left front wheel, the right front wheel, the left rear wheel, and the right rear wheel. Since the inner circle radius is not the same as the outer circle radius when the vehicle is traveling on a curve, it is more complicated to calculate the distance, thereby increasing the calculation process of the real-time number of rotations. Therefore, directly obtaining the number of rotations of the wheels when the vehicle is traveling in a straight line can simplify the calculation process, improve efficiency and reduce costs.

[0096] Step S203, compare the real-time rotation number of the above-mentioned wheels with the reference rotation number of the above-mentioned wheels to obtain a comparison result; and determine the current tire pressure value of the above-mentioned wheels at least based on the above-mentioned comparison result, and the above-mentioned comparison result includes whether the real-time rotation number of the above-mentioned wheels is the same as the reference rotation number of each of the above-mentioned wheels.

[0097] Specifically, since the current tire pressure value corresponding to each real-time number of rotations is different, and the benchmark data may not be able to accurately obtain the tire pressure value corresponding to each number of rotations (that is, the benchmark data may only be two groups), it is necessary to first compare the real-time number of rotations with the benchmark number of rotations recorded in the benchmark data. If a benchmark number of rotations in the benchmark data is exactly the same as the real-time number of rotations, the benchmark tire pressure value corresponding to the benchmark number of rotations can be directly determined as the current tire pressure value. If there is no benchmark number of rotations in the benchmark data that is the same as the real-time number of rotations, the corresponding current tire pressure value will be obtained through subsequent calculation.

[0099] Step S201, obtaining reference data of the wheels, the reference data of the wheels including reference tire pressure values ​​of the wheels and reference rotation numbers of the wheels corresponding to each reference tire pressure value, the reference rotation numbers of the wheels being the number of rotations of the wheels per predetermined kilometer of straight-line travel when the tire pressure value of the wheels is the reference tire pressure value;

[0100] Step S202, obtaining the real-time rotation number of the wheel in real time, where the real-time rotation number of the wheel is the actual rotation number of the vehicle when the vehicle travels a predetermined number of kilometers in a straight line;
