[0001] This invention relates to the field of automotive inspection technology, and in particular to a tire wear indicator method, device, terminal equipment, and storage medium. Background Technology
[0002] With the continuous development of the automotive market and the increasing demand for automotive safety, tire pressure monitoring technology has gradually become a hot topic in the field of automotive electronics. Tire pressure monitoring refers to the real-time monitoring of the tire pressure of a vehicle through sensors. When the tire pressure is abnormal, the driver is promptly reminded to inflate the tires, thereby ensuring vehicle driving safety and tire lifespan.
[0003] However, existing tire pressure monitoring products generally only issue warnings when the tire pressure is outside the standard range or when there is a rapid leak. During long-term driving, when tires wear down due to external factors, the tire pressure may still be at a normal value. When the car is driving at high speed, a tire blowout may occur, causing an accident.
[0004] Therefore, a tire wear indicator method is needed for real-time tire pressure monitoring to solve the problem that the pressure values at various points on the tire cannot be accurately detected, which leads to the inability to warn of tire blowouts and cause accidents.

[0045] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0046] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0047] The main solution of this invention is as follows: Vehicle information is obtained by querying the vehicle's electronic control unit (ECU); sensor placement points are analyzed based on the tire information to obtain sensor deployment points; sensors are deployed on the vehicle according to the deployment points, and deployment results are obtained. The tire size is analyzed to obtain the tire's driving cycle; tire pressure is detected using pressure sensors based on the driving cycle, and several pressure differences are obtained. An error value is calculated based on the average pressure and the several pressure differences; the error value is compared with a preset error threshold; if the error value is less than the error threshold, the analysis result is output as "Tire is good"; if the error value is above the error threshold, the analysis result is output as "Tire wear". When the analysis result is "Tire wear", wear information is generated based on the deployment results and the error value; an alarm device is accessed through the vehicle's ECU, and an alarm message is issued through the alarm device based on the wear information. Based on the deployment results and error values, regional analysis is performed to obtain the wear area of the vehicle tires; the wear degree of the vehicle tires is obtained based on the error values; information is generated based on the wear degree and wear area to obtain wear information. Based on the wear information and vehicle information, a diagnosis is performed using a preset diagnostic device to obtain the diagnostic results; the vehicle owner information is obtained through the vehicle information, and the diagnostic results are sent according to the contact information in the owner information. This solves the problem of inaccurate detection of pressure values at various tire positions, which leads to the inability to warn of tire blowouts and cause accidents, and realizes tire wear warning, improving the efficiency of tire wear warning. Based on the present invention, considering that in reality, tire pressure monitoring products generally only issue warnings when the tire pressure is outside the standard range or when there is rapid leakage, while the tire pressure may still be at a normal value when the tire wears due to external influences during long-term driving, tire blowouts may occur during high-speed driving, causing accidents and affecting safety, a tire wear warning method is designed. The effectiveness of the tire wear warning method of the present invention is verified when warning of tire wear. Finally, the efficiency of tire wear warning is significantly improved by the present invention.
[0048] The embodiments of the present invention take into account that, when related technologies provide tire wear warnings, tire pressure products generally only issue an alarm when the tire pressure is outside the standard range or when there is a rapid leak. However, when tires wear out due to external factors during long-term driving, the tire pressure may still be at a normal value. When the car is driving at high speed, a tire blowout may occur, causing an accident. Therefore, this method has the problem of low safety.
[0049] Therefore, this invention addresses the problem that tire pressure monitoring systems typically only issue warnings when tire pressure is outside the standard range or when there is a rapid leak. However, during prolonged driving, tires may wear down due to external factors while still maintaining normal tire pressure. This can lead to tire blowouts and accidents at high speeds, compromising safety. Based on this, a tire wear warning method was designed. The effectiveness of this method was verified during tire wear warning demonstrations, and the efficiency of tire wear warnings was significantly improved.
[0050] Specifically, refer to Figure 1 , Figure 1 This is a schematic diagram of the functional modules of the terminal device to which the tire wear indicator of this invention belongs. The tire wear indicator can be a device capable of indicating tire wear, independent of the terminal device, and can be implemented on the terminal device in hardware or software form. The terminal device can be a smart mobile device with data processing capabilities, such as a mobile phone or tablet computer, or a fixed terminal device or server with data processing capabilities.
[0051] In this embodiment, the terminal device to which the tire wear indicator belongs includes at least an output module 110, a processor 120, a memory 130, and a communication module 140.
[0052] The memory 130 stores the operating system and a tire wear warning program. The tire wear warning device can use pre-deployed pressure sensors to detect tire pressure in the vehicle's tires and obtain several pressure difference values. When the analysis result indicates tire wear, an alarm message is issued. The tire wear warning program provides tire wear warnings, and the resulting information is stored in the memory 130. The output module 110 can be a display screen, etc. The communication module 140 can include a Wi-Fi module, a mobile communication module, and a Bluetooth module, etc., and communicates with external devices or servers through the communication module 140.
[0053] When the tire wear warning program in memory 130 is executed by the processor, it performs the following steps:
[0054] The tire pressure of the vehicle's tires is detected using pre-deployed pressure sensors to obtain several pressure difference values.
[0055] The tire pressure of the vehicle's tires is detected using pre-deployed pressure sensors to obtain several pressure difference values.
[0056] When the analysis result indicates tire wear, an alarm message is issued.
[0057] Furthermore, when the tire wear warning program in memory 130 is executed by the processor, it also performs the following steps:
[0058] Vehicle information is obtained by querying the vehicle's electronic control unit (ECU).
[0059] Based on the tire information of the vehicle information, sensor location analysis is performed to obtain sensor deployment points;
[0060] The vehicle is equipped with sensors based on the sensor deployment points, and the deployment results are obtained.
[0061] Furthermore, when the tire wear warning program in memory 130 is executed by the processor, it also performs the following steps:
[0062] The tire size of the vehicle is analyzed periodically to obtain the driving cycle of the vehicle tires;
[0063] Based on the driving cycle, the tire pressure of the vehicle is detected by the pressure sensor to obtain several pressure difference values.
[0064] Furthermore, when the tire wear warning program in memory 130 is executed by the processor, it also performs the following steps:
[0065] Based on the average pressure, the error value is obtained by calculating the difference using the several pressure differences;
[0066] Compare the error value with a preset error threshold;
[0067] If the error value is less than the error threshold, the output analysis result is "Tire is good".
[0068] If the error value is above the error threshold, the output analysis result is tire wear.
[0069] Furthermore, when the tire wear warning program in memory 130 is executed by the processor, it also performs the following steps:
[0070] When the analysis result indicates tire wear, wear information is generated based on the deployment result and error value.
[0071] The alarm device is obtained through the vehicle's ECU, and an alarm message is issued through the alarm device based on the wear information.
[0072] Furthermore, when the tire wear warning program in memory 130 is executed by the processor, it also performs the following steps:
[0073] Based on the deployment results and error values, regional analysis is performed to obtain the wear area of the vehicle tires;
[0074] The wear level of the vehicle tires is obtained based on the error value;
[0075] Information is generated based on the degree of wear and the wear area to obtain wear information.
[0076] Furthermore, when the tire wear warning program in memory 130 is executed by the processor, it also performs the following steps:
[0077] Based on the wear information and the vehicle information, a diagnosis is performed using a preset diagnostic device to obtain the diagnostic results;
[0078] The vehicle owner's information is obtained through the vehicle information, and the diagnostic results are sent according to the contact information in the vehicle owner's information.
[0079] This embodiment, through the above-described scheme, specifically uses pre-deployed pressure sensors to detect tire pressure in vehicle tires and obtain several pressure difference values; it then uses these pre-deployed pressure sensors to detect tire pressure in vehicle tires and obtains several pressure difference values; when the analysis result indicates tire wear, an alarm message is issued. By using pre-deployed pressure sensors to detect tire pressure in vehicle tires and analyzing the tire wear based on the tire pressure detection results, tire wear information is obtained, which can solve the problem of inaccurate detection of pressure values at various tire locations, leading to the inability to provide early warning of tire blowouts and causing accidents. Based on this invention, considering that in reality, tire pressure monitoring products generally only issue alarms when the tire pressure is outside the standard range or when there is a rapid leak, while the tire pressure may still be at a normal value when the tire wears due to external influences during long-term driving, tire blowouts may occur at high speeds, causing accidents and compromising safety, a tire wear warning method is designed. The effectiveness of the tire wear warning method of this invention is verified when providing tire wear warnings, and the efficiency of tire wear warnings using this invention is significantly improved.
[0080] Reference Figure 2 , Figure 2 This is a schematic flowchart of an exemplary embodiment of the tire wear warning method of the present invention. The tire wear warning method includes:
[0081] Step S04: Use pre-deployed pressure sensors to detect tire pressure in the vehicle tires and obtain several pressure difference values;
[0082] The subject executing the method in this embodiment can be a tire wear indicator device, a tire wear indicator terminal device, or a server. This embodiment takes a tire wear indicator device as an example, which can be integrated into a terminal device with data processing capabilities.
[0083] It should be clear that with the continuous development of the automobile market and the increasing frequency of vehicle use, vehicle safety has also received more attention. According to relevant data analysis, about 50% of traffic accidents each year are caused by tire problems, of which tire blowouts account for more than 70%. Therefore, it can be seen that if tires are not properly protected, the probability of causing an accident is relatively high. However, the current methods for monitoring tire pressure generally only issue an alarm when the tire pressure is outside the standard range or when there is a rapid leak. During long-term driving, when tires wear down due to external factors, the tire pressure may still be at a normal value. When the car is driving at high speed, a tire blowout may occur, leading to an accident.
[0084] To address the aforementioned issues, this embodiment employs pressure sensors pre-deployed on the tires to monitor vehicle tires. The number and location of these pressure sensors should be determined based on actual business needs. In this embodiment, the tire is divided into eight equal parts, and pressure sensors are deployed at the same location in each area.
[0085] The system receives the value returned by the pressure sensor and calculates the pressure difference for each tire rotation cycle. In this embodiment, the calculation interval is one driving cycle, but in other embodiments, it can be multiple cycles.
[0086] Step S05: Use pre-deployed pressure sensors to detect tire pressure in the vehicle tires and obtain several pressure difference values;
[0087] The average pressure value is obtained by averaging the pressure difference values returned by each sensor. For example, in this embodiment, 8 pressure sensors are used for monitoring. Therefore, the pressure difference values obtained by the 8 sensors are added together to obtain the total pressure difference value. Finally, the total pressure difference value is divided by the number of pressure sensors (i.e., 8) to obtain the average pressure value.
[0088] Error values are obtained by calculating the average pressure and the pressure difference. Threshold analysis is then performed using the error values and the error threshold to obtain the analysis results. In this embodiment, the analysis results are roughly divided into two types: one is that when the error value is greater than the error threshold, the analysis result is that the tire is worn; the other is that when the error value is less than the error threshold, the analysis result is that the tire is not worn. It should be clear that since there are 8 pressure sensors, the final analysis result is how many of the 8 sensors have error values that are greater than or less than the error threshold, thereby determining the specific situation of whether the tire is worn.
[0089] Step S06: When the analysis result indicates tire wear, an alarm message is issued.
[0090] When the analysis result indicates tire wear, it means the tire pressure is abnormal, potentially posing a risk of a tire blowout. If the vehicle is in motion at this time, it could lead to an accident, thus requiring a warning message. However, the warning message should be issued according to the current vehicle status. If the warning is sent via text message or a loud noise while driving, the driver may not receive the warning or may be startled. Therefore, when the vehicle is in motion, the warning message is sent through the vehicle's ECU. If the vehicle is stationary, the warning message can be sent via a mobile device to inform the driver of the tire wear status before driving. However, there is a possibility that the driver may not see the warning message on the mobile device. Therefore, when starting the vehicle, the vehicle's ECU simultaneously sends a warning message until the tire pressure monitoring returns to normal.
[0091] Specifically, step S05, which involves performing threshold analysis based on the average pressure and the pressure difference using a preset error threshold to obtain the analysis results, includes:
[0092] Step S051: Based on the average pressure, calculate the difference using the several pressure differences to obtain the error value;
[0093] Step S052: Compare the error value with a preset error threshold;
[0094] Step S053: If the error value is less than the error threshold, the analysis result is output as "Tire is good".
[0095] Step S054: If the error value is above the error threshold, the analysis result is output as tire wear.
[0096] After obtaining the average pressure value and the pressure difference value, an error analysis is performed on the pressure difference value and the average pressure value to obtain the error value of each deployed sensor. For example, if there are currently 8 sensors, 6 of them have an error value of 0.99, one has an error value of 0.85, and one has an error value of 1.15.
[0097] Threshold analysis is performed by comparing the pre-set error threshold with the obtained error value. For example, if the current error threshold is set to 0.95 to 1.05, then the range of 0.95 to 1.05 is considered normal. At this time, the six sensors with an error value of 0.99 are normal, but the sensor with an error value of 0.85 indicates that the tire pressure is too low, and the sensor with an error value of 1.15 indicates that the tire pressure is too high.
[0098] When all error values are less than the error threshold (greater than 0.95 or less than 1.05), the output analysis result is "Tire is good". When there are error values above the error threshold (less than or equal to 0.95 or greater than or equal to 1.05), the output analysis result is "Tire wear".
[0099] This embodiment, through the above-described scheme, specifically uses pre-deployed pressure sensors to detect tire pressure in the vehicle's tires and obtain pressure difference values; it then uses these pre-deployed pressure sensors to detect tire pressure in the vehicle's tires and obtains several pressure difference values; when the analysis result indicates tire wear, an alarm message is issued. This achieves tire wear warning, solving the problem of inaccurate pressure value detection at various tire locations, which leads to the inability to warn of tire blowouts and thus accidents, thereby improving the safety of tire wear warnings.
[0100] Reference Figure 3 , Figure 3 This is a schematic flowchart illustrating another exemplary embodiment of the tire wear indication method of the present invention.
[0101] Based on the above Figure 2 In the embodiment shown, before step S04, which involves using a pre-deployed pressure sensor to detect tire pressure in the vehicle tires and obtain several pressure difference values, the following steps are also included:
[0102] Step S01: Query the vehicle's electronic control unit (ECU) to obtain vehicle information;
[0103] Step S02: Analyze the sensor locations based on the tire information of the vehicle information to obtain the sensor deployment points;
[0104] Step S03: Deploy sensors on the vehicle according to the sensor deployment points and obtain the deployment results.
[0105] Before monitoring tire pressure on a vehicle, pressure sensors need to be deployed. This can be done by querying the vehicle's electronic control unit (ECU) to obtain vehicle information, including but not limited to tire information, owner information, and vehicle model information. Specific tire information can include tire size, tire brand, and tire material.
[0106] The sensor location analysis using the acquired tire information should be understood as follows: a vehicle tire experiences different pressures due to its material and size. Combined with the weight of the vehicle body, the pressure experienced by the vehicle also varies. Therefore, the vehicle tire can be divided into eight equal parts for sensor deployment, and a sensor deployment point can be set at the center of each of the eight areas.
[0107] Finally, based on the obtained sensor deployment points, the corresponding pressure sensors are deployed to obtain the deployment results.
[0108] After completing the pressure sensor step, the tire pressure can be tested on the vehicle tires. Therefore, in S04, the steps of using a pre-deployed pressure sensor to detect the tire pressure of the vehicle tires and obtain several pressure difference values include:
[0109] Step S041: Perform a periodic analysis based on the tire size of the vehicle information to obtain the driving cycle of the vehicle tires;
[0110] Step S042: Based on the driving cycle, the tire pressure of the vehicle tires is detected by the pressure sensor to obtain several pressure difference values.
[0111] Since the tires rotate during vehicle operation, the pressure they experience is not constant but changes in real time. Therefore, it is necessary to calculate the pressure change value of each pressure sensor during one rotation cycle. First, perform a cycle analysis based on the tire size in the vehicle information to obtain the vehicle tire's driving cycle.
[0112] Based on the vehicle's driving cycle, tire pressure is detected using a pressure sensor to obtain the maximum and minimum pressure values. It can be understood that the pressure value is the maximum when the tire is in contact with the ground and the minimum when it is away from the ground. The pressure difference is obtained by subtracting the minimum pressure value from the maximum pressure value.
[0113] This embodiment, through the above-described scheme, specifically queries the vehicle's electronic control unit (ECU) to obtain vehicle information; analyzes sensor locations based on tire information to determine sensor deployment points; and deploys sensors on the vehicle according to these deployment points, obtaining the deployment results. This achieves the deployment of pressure sensors and the calculation of pressure differences, solving the problem of lacking a corresponding method for calculating pressure values in various areas of the vehicle, and improving the accuracy of tire wear warnings.
[0114] Reference Figure 4 , Figure 4 This is a schematic flowchart illustrating another exemplary embodiment of the tire wear indication method of the present invention.
[0115] Based on the above Figure 2 In the embodiment shown, step S06, which involves issuing a warning message when the analysis result indicates tire wear, includes:
[0116] Step S061: When the analysis result is tire wear, generate wear information based on the deployment result and error value;
[0117] Step S062: Obtain the alarm device through the vehicle's ECU, and issue alarm information through the alarm device based on the wear information.
[0118] Once the analysis results show that the tires are worn, it can be concluded that the tire pressure of the vehicle is abnormal. At this time, there is a risk of tire blowout, so it is necessary to issue a warning message to inform the owner or driver of the situation.
[0119] Since there are multiple sensors deployed at this time, when an alarm is issued, it may not know which specific area is worn, and it is also unaware whether the current tire pressure is too high or too low. Therefore, the corresponding wear information is generated based on the deployment results and error values.
[0120] After obtaining tire wear information, the corresponding alarm device is accessed through the vehicle's ECU. It should be clear that the vehicle's status may be either moving or parked, and the alarm should be triggered differently in each case. If the vehicle is not moving, the likelihood of no accident is low, so the owner's contact information can be obtained through the vehicle's ECU, and the corresponding wear information can be sent to the owner. However, the owner may have accidentally deleted the alarm message or missed it before driving the vehicle. In this case, when the owner starts the vehicle, an alarm will be triggered simultaneously. Since the vehicle is not moving, the alarm volume can be relatively high, but it must be appropriate for the actual situation to avoid causing hearing damage to the driver. If the alarm is triggered while the vehicle is moving, the alarm should be triggered based on the actual driving conditions. If the vehicle is traveling at high speed or on complex road sections, a soft alarm should be triggered to inform the owner.
[0121] Specifically, step S061, which involves generating information based on the deployment results and error values to obtain wear information, includes:
[0122] Step S0611: Perform regional analysis based on the deployment results and error values to obtain the wear area of the vehicle tires;
[0123] Step S0612: Obtain the wear degree of the vehicle tires based on the error value;
[0124] Step S0613: Generate information based on the wear degree and wear area to obtain wear information.
[0125] Since there are a large number of sensors, simply issuing a warning about tire wear would not be enough to inform the driver of the specific situation. Therefore, based on the deployment results, namely the location of the sensors and the error values transmitted by the sensors, regional analysis is performed to determine the wear area of the vehicle's tires.
[0126] After obtaining the wear area of the vehicle's tires, it is also necessary to analyze it in conjunction with the error value to determine whether the current area is due to excessive tire pressure or excessive tire pressure, so that the car owner can take corresponding actions.
[0127] Finally, information on tire wear is generated using the degree of tire wear and the wear area, resulting in tire wear information for the vehicle.
[0128] This embodiment, through the above-described scheme, specifically generates wear information based on the deployment results and error values when the analysis result indicates tire wear. The vehicle's ECU then obtains the warning information and issues an alarm based on the wear information. Therefore, by generating wear information through the sensor deployment area and error values, the problem of drivers being unable to know the specific tire wear condition is solved, improving the efficiency of tire wear warnings.
[0129] Reference Figure 5 , Figure 5 This is a schematic flowchart illustrating another exemplary embodiment of the tire wear indication method of the present invention.
[0130] Based on the above Figure 2 In the embodiment shown, after step S06, which involves issuing an alarm message when the analysis result indicates tire wear, the method further includes:
[0131] Step S07: Based on the wear information and the vehicle information, perform a diagnosis using a preset diagnostic device to obtain the diagnostic results;
[0132] Step S08: Obtain the vehicle owner information through the vehicle information, and send the diagnostic results according to the contact information in the vehicle owner information.
[0133] Specifically, after obtaining the vehicle's alarm information, diagnostic equipment can be used to diagnose the vehicle in order to obtain a solution:
[0134] First, the acquired wear information, combined with vehicle information, is input into a preset diagnostic device for diagnosis to obtain diagnostic results. The diagnostic results include at least the cause of the wear, the solution, and the nearest repair shop.
[0135] Then, the vehicle owner's information is obtained through the vehicle information, and the owner's contact information is obtained based on the owner's information;
[0136] Finally, the diagnostic results obtained by the diagnostic equipment are sent to the vehicle owner's contact information so that the user can know the specific repair methods for the vehicle.
[0137] This embodiment, through the above-described scheme, specifically by using a preset diagnostic device to perform diagnosis based on the wear information and vehicle information, and obtaining diagnostic results; by obtaining the vehicle owner information through the vehicle information, and sending the diagnostic results according to the contact information in the owner information. Therefore, by diagnosing the vehicle's tire wear information through a preset diagnostic device, it is convenient for users to carry out repairs or find repair shops, solving the problem of not having a corresponding solution after wear occurs, and improving the efficiency of tire wear repair.
[0138] Furthermore, embodiments of the present invention also provide a tire wear indicator device, the tire wear indicator device comprising:
[0139] The detection module is used to detect tire pressure of the vehicle tires using pre-deployed pressure sensors and obtain several pressure difference values.
[0140] The analysis module is used to detect tire pressure in the vehicle's tires using pre-deployed pressure sensors and obtain several pressure difference values.
[0141] The alarm module is used to issue an alarm message when the analysis result indicates tire wear.

[0146] Compared to existing technologies, the tire wear warning method, device, terminal equipment, and storage medium proposed in this invention use pre-deployed pressure sensors to detect tire pressure in vehicle tires and obtain several pressure difference values. When the analysis result indicates tire wear, an alarm message is issued. This solves the problem of inaccurate detection of pressure values at various tire locations, leading to the inability to warn of tire blowouts and causing accidents. It achieves tire wear warning and improves the efficiency of tire wear warning. Based on this invention, considering that tire pressure monitoring products typically only issue alarms when tire pressure is outside the standard range or when there is rapid air leakage, while tires may still be at normal pressure during prolonged driving due to external factors, potentially leading to tire blowouts and accidents at high speeds, thus compromising safety, a tire wear warning method was designed. The effectiveness of this method was verified during tire wear warning, and the efficiency of tire wear warning was significantly improved.
[0147] Compared with existing technologies, the solutions of the embodiments of the present invention have the following advantages:
[0148] 1. Determine the degree of tire wear by detecting changes in tire wear at different locations;
[0149] 2. Issue a warning to the car owner when the car tires are worn.
