[0002] The tire pressure of an automobile tire plays an extremely important role in vehicle driving safety, comfort, operating energy consumption, and wear. Abnormal tire pressure can affect the comfort of vehicle driving, or even cause abnormal wear of the tire or damage to the internal mechanism of the tire, resulting in driving safety hazards.

[0003] Currently, a tire pressure monitoring device is usually installed on an automobile to monitor the tire pressure of the tire in real time and to issue a reminder when the tire pressure of the tire is abnormal, prompting the user to go to a professional repair shop to adjust the tire pressure. However, this reminder cannot immediately solve the tire pressure abnormality, and the tire pressure abnormality will be fed back to the vehicle that is driving in real time, causing driving safety hazards or accidents, such as vehicle deviation, deceleration, tire burst, and the like. If the driver does not have experience in dealing with the vehicle driving abnormality caused by the tire pressure abnormality and does not timely handle the vehicle driving abnormality, the tire wear will be aggravated, and the driving vehicle may even cause more serious safety accidents.

However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.

[0027] The tire pressure monitoring method, device, electronic device and readable storage medium according to the embodiments of the present application will be described in detail below with reference to the drawings.

[0028] Figure 1 is a flow diagram of a tire pressure monitoring method for a tire provided by an embodiment of the present application. Figure 1 The tire pressure monitoring method for a tire can be executed by a controller provided on a target vehicle. As shown in Figure 1 , the tire pressure monitoring method comprises:

[0029] S101: monitoring the real-time tire pressure of all tires on the target vehicle;

[0030] S102: for each axle line, determining the tire pressure difference between the real-time tire pressure of all tires corresponding to the axle line;

[0031] S103: determining whether there is an axle line whose tire pressure difference is greater than a preset tire pressure difference;

[0032] S104: if yes, determining that real-time tire pressures of all tires corresponding to the axle line include a first tire pressure and a second tire pressure, and determining a tire pressure relationship among the first tire pressure, the second tire pressure, a preset tire pressure upper limit and a preset tire pressure lower limit; wherein the preset tire pressure upper limit is greater than the preset tire pressure lower limit, the first tire pressure is less than the second tire pressure, the difference between the second tire pressure and the first tire pressure is the tire pressure difference, and the first tire pressure and the second tire pressure correspond to a first tire and a second tire, respectively;

[0033] S105: according to the tire pressure relationship, determining that the tire to be adjusted is at least one of all the tires, and determining a target tire pressure of each tire to be adjusted, the target tire pressure being between the preset tire pressure lower limit and the preset tire pressure upper limit and causing the adjusted tire pressure difference between the first tire and the second tire to be not greater than the preset tire pressure difference;

[0034] S106: using a tire pressure adjustment system arranged on the target vehicle to adjust the real-time tire pressure of the tire to be adjusted according to the target tire pressure.

[0035] It can be understood that if the determination result of step S103 is no, the action of step S101 is continued to be performed.

[0036] It can be understood that the axle lines on the target vehicle at least include a front axle line and a rear axle line, and the tires on each axle line include a left tire and a right tire. Therefore, for each axle line, the tire pressure difference between the real-time tire pressures of the left tire and the right tire is calculated, and the tire pressure difference is a non-negative value. In the calculation, the real-time tire pressure of any tire on the axle line can be directly selected to be subtracted from the real-time tire pressure of another tire to obtain the tire pressure difference, or the real-time tire pressures of the two tires on the axle line can be compared in size, and the larger real-time tire pressure is subtracted from the smaller real-time tire pressure to obtain the tire pressure difference.

[0037] After obtaining the tire pressure difference of each axle line, the size of each tire pressure difference and the preset tire pressure difference is determined. If the tire pressure difference of a certain axle line is greater than the preset tire pressure difference, the vehicle will be deviated, and the tire pressure of the tire on the axle line needs to be adjusted, that is, steps S104-S106 are entered. It should be noted that steps S104-S106 are all for the tires and their real-time tire pressures on the axle line whose tire pressure difference is greater than the preset tire pressure difference in step S103.

[0038] In the specific step S104, the real-time tire pressure of the tire on the axle line is compared, the smaller real-time tire pressure is taken as the first tire pressure P1, and the corresponding tire is the first tire; the larger real-time tire pressure is taken as the second tire pressure P2, and the corresponding tire is the second tire; the preset upper limit Pmax and the preset lower limit Pmin of the tire pressure are known quantities preset in advance, and are the maximum tire pressure and the minimum tire pressure of the corresponding tire that can work normally without being damaged. The first tire pressure P1, the second tire pressure P2, the preset upper limit Pmax and the preset lower limit Pmin of the tire pressure are compared to determine the tire pressure relationship.

[0039] In step S105, the tire to be adjusted is determined according to the tire pressure relationship, and the target tire pressure of the tire to be adjusted is determined, so that the tire pressure of the tire to be adjusted is adjusted according to the relationship between the target tire pressure and the real-time tire pressure in step S106. It can be understood that the target vehicle is provided with a tire pressure adjustment system, and the tire pressure adjustment system can inflate or deflate the tire when receiving an adjustment instruction, so as to achieve the effect of reducing or increasing the tire pressure. Generally, the target tire pressure confirmed in step S105 is generally between the first tire pressure P1 and the second tire pressure P2, and generally needs to meet the implicit requirement that it is not less than the preset upper limit Pmax of the tire pressure and not greater than the preset lower limit Pmin of the tire pressure. The purpose of steps S104-S106 is to adjust the tire pressure so that the tire pressure difference is not greater than the preset tire pressure difference, and the specific adjustment object can be the second tire, the first tire, or the first tire and the second tire. The specific adjustment object can be determined according to the implementation difficulty and the tire pressure relationship, and the pressure adjustment measure of the second tire is generally to reduce the tire pressure, and the adjustment measure of the first tire is generally to increase the tire pressure.

[0040] Considering the adjustment difficulty of the tire pressure adjustment system, the target tire pressure can be determined by reducing the tire pressure as a measure, except for the case that the real-time tire pressure exceeds the preset tire pressure interval. When the real-time tire pressure exceeds the preset tire pressure interval, it is required to return the tire pressure of the tire to the preset tire pressure interval through the tire pressure adjustment system. The preset tire pressure interval refers to the interval between the preset upper limit Pmax and the preset lower limit Pmin of the tire pressure.

[0041] According to different tire pressure relationships, different target tire pressures can be obtained as adjustment means:

[0042] When the tire pressure relationship is: the preset lower limit of tire pressure is less than the first tire pressure and the second tire pressure is less than the preset upper limit of tire pressure, the second tire is determined as the tire to be adjusted, and the target tire pressure of the second tire is determined as the third tire pressure, which is not less than the first tire pressure and not greater than the sum of the first tire pressure and the preset tire pressure difference. When the current tire pressure relationship is Pmin < P1 < P2 < Pmax, the second tire is selected as the tire to be adjusted, and the target tire pressure is determined as P3, P1 ≤ P3 ≤ P1 + ΔP0, wherein ΔP0 is the preset tire pressure difference. At this time, the second tire is taken as the tire to be adjusted, and the tire pressure adjustment system is used to deflate the second tire. The above tire pressure variables satisfy the following relationship:

[0043] Pmin < P1 ≤ P3 ≤ P1 + ΔP0 < P2 < Pmax;

[0044] Based on the minimum adjustment amount, P3 = P1 + ΔP0 can be selected, and subsequent actions are performed.

[0045] Similarly, when the tire pressure relationship is: the first tire pressure is less than the preset lower limit of tire pressure, which is less than the second tire pressure, which is less than the preset upper limit of tire pressure, and the difference between the second tire pressure and the preset lower limit of tire pressure is not greater than the preset tire pressure difference, the first tire is determined as the tire to be adjusted, and the target tire pressure of the first tire is determined as the preset lower limit of tire pressure. When the current tire pressure relationship is P1 < Pmin < P2 < Pmax, P2-Pmin ≤ ΔP0. At this time, the first tire must be inflated to the preset lower limit of tire pressure, P2-Pmin ≤ ΔP0, and the second tire can not be adjusted. Therefore, the first tire is determined as the tire to be adjusted, and the target tire pressure is determined as the preset lower limit of tire pressure Pmin. The tire pressure adjustment system is used to inflate the first tire to the preset lower limit of tire pressure Pmin.

[0046] Similarly, when the tire pressure relationship is: the first tire pressure is less than the preset lower limit of tire pressure, which is less than the second tire pressure, which is less than the preset upper limit of tire pressure, and the difference between the second tire pressure and the preset lower limit of tire pressure is greater than the preset tire pressure difference, the first tire and the second tire are determined as the tires to be adjusted;

[0047] The target tire pressures corresponding to the first tire and the second tire are determined as the preset lower limit of tire pressure and the fourth tire pressure, respectively.

[0048] The fourth tire pressure is not less than the preset lower limit of tire pressure, and the fourth tire pressure is not greater than the sum of the preset lower limit of tire pressure and the preset tire pressure difference.

[0049] The current tire pressure relationship is P1 < Pmin < P2 < Pmax, and P2-Pmin > ΔP0. At this time, the first tire must first increase the tire pressure to the preset lower limit of tire pressure Pmin, and P2-Pmin > ΔP0. Even if the tire pressure of the first tire is increased to the preset lower limit of tire pressure Pmin, the tire pressure difference between the first tire and the second tire is still greater than the preset tire pressure difference ΔP0. Therefore, in order to improve the adjustment efficiency, the pressure of the first tire is increased at the same time as the pressure of the second tire is decreased. Therefore, the first tire and the second tire are determined to be the tires to be adjusted, the target tire pressure of the first tire is set to the preset lower limit of tire pressure Pmin, and the target tire pressure of the second tire is set to the fourth tire pressure P4, Pmin ≤ P4 ≤ Pmin + ΔP0.

[0050] The above tire pressure variables have the following relationship:

[0051] P1 < Pmin ≤ P4 ≤ Pmin + ΔP0 < P2 < Pmax;

[0052] Based on the minimum adjustment amount, P4 = Pmin + ΔP0 can be selected, and subsequent actions are performed.

[0053] Similarly, when the tire pressure relationship is: the preset lower limit of tire pressure is less than the first tire pressure, which is less than the preset upper limit of tire pressure, which is less than the second tire pressure, the second tire is determined to be the tire to be adjusted.

[0054] The target tire pressure value of the second tire is determined to be the fifth tire pressure, which is not greater than the preset upper limit of tire pressure, and is not greater than the sum of the first tire pressure and the preset tire pressure difference, and is not less than the first tire pressure.

[0055] The current tire pressure relationship is Pmin < P1 < Pmax < P2, and the first tire can not be adjusted in pressure, and only the second tire can be adjusted in pressure. Therefore, the second tire is determined to be the tire to be adjusted, and the target tire pressure thereof is determined to be the fifth tire pressure P5, P5 ≤ Pmax, and P5 ≤ P1 + ΔP0, and P5 ≥ P1.

[0056] Based on the minimum adjustment amount, P5 = min (Pmax, P1 + ΔP0) can be selected, and subsequent actions are performed.

[0057] Further, in addition to the tire pressure adjustment for the case where the tire pressure difference exceeds the preset tire pressure difference, the real-time tire pressure of each tire should also meet the condition that the tire pressure is not greater than the preset upper limit of tire pressure and is not less than the preset lower limit of tire pressure. Therefore, the method of the embodiment further comprises:

[0058] determining whether the real-time tire pressure of the tire is between the preset upper limit of tire pressure and the preset lower limit of tire pressure;

[0059] If not, using the tire pressure adjustment system to adjust the real-time tire pressure of the tire whose real-time tire pressure is greater than the preset upper limit of tire pressure or whose real-time tire pressure is less than the preset lower limit of tire pressure.

[0060] It can be understood that, based on the least amount of adjustment, if the real-time tire pressure is greater than the preset upper limit of tire pressure, the tire pressure is reduced to the preset upper limit of tire pressure, and if the real-time tire pressure is less than the preset lower limit of tire pressure, the tire pressure is increased to the preset lower limit of tire pressure. Further, based on the best tire pressure effect, the tire pressure can be further adjusted to a standard tire pressure between the preset upper limit of tire pressure and the preset lower limit of tire pressure. The standard tire pressure refers to the optimal tire pressure value of the vehicle under cold vehicle conditions, which is obtained by balancing various vehicle performances according to the tire model, the static load of the wheel, and the vehicle simulation and test under multiple working conditions during the vehicle research and development process.

[0061] Further, the preset upper limit of tire pressure and the preset lower limit of tire pressure in the embodiment are not constant amounts, but will change with the actual driving state. The method of the embodiment further comprises:

[0062] monitoring a driving state parameter of the target vehicle, the driving state parameter including one or more of a temperature parameter, a driving parameter, and a road surface parameter;

[0063] adjusting the preset lower limit of tire pressure and the preset upper limit of tire pressure according to the driving state parameter.

[0064] According to the change of the driving state parameter, the tire pressure range in which the tire normally works will change, so the preset lower limit of tire pressure and the preset upper limit of tire pressure will be increased or decreased. The preset lower limit of tire pressure and the preset upper limit of tire pressure are adjusted in real time, and then applied to the method implementation of steps S103-S106.

[0065] The embodiment of the application adjusts the tire pressure when the tire pressure difference of the tires on the same axle line exceeds the preset tire pressure difference by monitoring the real-time tire pressure of the current tire, reduces the negative impact of the large tire pressure difference on the tire and vehicle driving as much as possible, reduces the degree of expansion of the negative impact, and thus improves the reliability of vehicle driving.
