Technical Field

[0001] This invention relates to the automotive field, and in particular to a tire monitoring method, system, and vehicle. Background Technology

[0002] Currently, in the automotive industry, tire pressure and temperature are typically monitored. When problems arise with tire pressure or temperature, a warning light will illuminate on the digital instrument cluster, alerting the driver and potentially preventing accidents.

Often, tire problems exist without the driver's timely awareness, increasing the probability of an accident.

[0045] Figure 4 This is a schematic diagram of a tire monitoring system provided in an embodiment of the present invention. Detailed Implementation

[0046] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0047] This invention provides a method for tire monitoring, referring to... Figure 1 , Figure 1 A flowchart of a tire monitoring method provided in an embodiment of the present invention is shown below. Figure 1 As shown, the method includes:

[0048] Step 100: Power on the vehicle and obtain the current values ​​of multiple dimensional parameters of the vehicle's tires.

[0049] In this embodiment of the invention, the vehicle's self-test system is activated by powering on the vehicle. The self-test obtains the current values ​​of multiple dimensions of the vehicle's tires. In one feasible embodiment, the self-test system of this invention can be integrated into the vehicle's existing self-test system, meaning the current values ​​of the multiple dimensions of the tires can be obtained through the existing system. In another feasible embodiment, the self-test system can be a standalone system. It can perform a self-test to obtain the current values ​​of the multiple dimensions of the tires after the vehicle is powered on, either before or after the existing self-test system has completed its self-test, or it can perform the self-test simultaneously with the existing system. It should be noted that regardless of the embodiment used, the current values ​​of the multiple dimensions of the tires can be obtained before the vehicle is started; therefore, this invention does not limit the scope of the self-test.

[0050] In this embodiment of the invention, obtaining the current values ​​of multiple dimensional parameters of the vehicle tires includes:

[0051] The monitoring system of this invention is integrated into the vehicle's original self-inspection system, and the vehicle's tire pressure and tire temperature data are obtained through the vehicle's self-inspection.

[0052] Based on the standard tire pressure data range, if the current tire pressure exceeds the standard tire pressure data range, it is recorded as one tire pressure abnormality, and the current cumulative number of tire pressure abnormalities is obtained. In practical applications, for a recording cycle, after each maintenance or fault code clearing, it will become a new recording cycle. Therefore, for the number of tire pressure abnormalities, it is necessary to monitor not only the number of tire pressure abnormalities in a single recording cycle, but also the cumulative number of tire pressure abnormalities throughout the entire life cycle. For example, if the number of tire pressure abnormalities in a single recording cycle exceeds the parameter threshold or the number of consecutive tire pressure abnormalities exceeds the maximum tolerance value for the entire life cycle, an alarm will be triggered directly.

[0053] Based on the standard range of tire temperature data, if the current tire temperature exceeds the standard range, it is recorded as one instance of abnormal tire temperature, and the current cumulative number of abnormal tire temperature instances is obtained. In practical applications, the monitoring method for the number of abnormal tire temperature instances is the same as that for the number of abnormal tire pressure instances.

[0054] The mileage is obtained from the odometer; in practical applications, the mileage data is obtained from the vehicle's existing mileage records, and what is recorded is the mileage within the tire's lifespan, not the vehicle's total mileage.

[0055] The mileage is obtained through a cloud server; in practical applications, the mileage is the mileage within the monitoring and recording period. However, the overall lifespan of the tires is also considered to determine whether they have exceeded their maximum service life.

[0056] By installing a camera in front of the vehicle, the road conditions are captured and uploaded to a cloud server. After AI analysis, the road conditions of the driving segment are obtained. In practical applications, the road conditions of the driving segment are monitored throughout its entire life cycle. That is, with each self-check of the vehicle, the parameters of the driving segment need to be accumulated.

[0057] Access maintenance records and tire repair information via cloud servers;

[0058] Maintenance records and tire repair information are uploaded to the cloud server by the 4S store after the vehicle has been maintained and / or repaired. In practice, maintenance records and tire repair information are both cumulative values ​​of the tire's lifespan.

[0059] By comparing and analyzing road surface information and single-trip driving time with original manufacturer durability test data, the wear level of a tire in a single trip can be obtained. In practical applications, tire wear monitoring measures the cumulative wear level of the tire over its lifespan.

[0060] In this embodiment of the invention, the recording cycle refers to a cycle from when the tire is fault-free to when it becomes faulty, but after the fault code is repaired or cleared, it becomes a completely new cycle.

[0061] The life cycle is defined as the period from when a tire begins to be used until it is replaced.

[0062] Step 200: Determine the initial weight of each of the multiple dimension parameters according to their respective importance levels; wherein, the higher the importance level, the higher the initial weight of each of the multiple dimension parameters.

[0063] refer to Figure 2 , Figure 2 This diagram illustrates a method for determining the initial weights of multiple dimensional parameters according to an embodiment of the present invention. In this embodiment, through analysis of extensive real-vehicle test data, the multiple dimensional parameters are divided into different importance levels based on their respective importance within the entire system. In specific applications, the initial weights of the multiple dimensional parameters can be divided into first initial weights, second initial weights, third initial weights, and fourth initial weights according to different importance levels; as the importance level increases, the initial weights of each dimensional parameter increase sequentially from the first to the fourth.

[0064] In this embodiment of the invention, through analysis of real vehicle test data, it was found that tire pressure data, tire temperature data, and the number of abnormal tire pressure and temperature readings have the highest importance level; mileage and tire repair information have the second highest importance level; vehicle age and maintenance records have the second lowest importance level; and road conditions and tire wear level have the lowest importance level. Therefore, the initialization weights of the four dimensions of tire pressure data, tire temperature data, and the number of abnormal tire pressure and temperature readings are assigned as the first initialization weight; the initialization weights of mileage and tire repair information are assigned as the second initialization weight; the initialization weights of vehicle age and maintenance records are assigned as the third initialization weight; and the initialization weights of road conditions and tire wear level are assigned as the fourth initialization weight. It should be noted that in this embodiment of the invention, the sum of the initialization weights of the multiple dimensions is 1.

[0065] Step 300: Determine the overall risk level of the tire based on the current values ​​and initial weights of the multiple dimension parameters.

[0066] In this embodiment of the invention, the current values ​​of the multiple dimension parameters of the vehicle tire need to be scored based on whether the current values ​​of the multiple dimension parameters exceed the corresponding parameter thresholds.

[0067] When the current value of at least one of the multiple dimension parameters exceeds the corresponding parameter threshold, the current value score of the dimension parameter is determined as the highest target score.

[0068] When the current values ​​of the multiple dimension parameters do not exceed the corresponding parameter thresholds, the current value scores of the multiple dimension parameters are determined as scores between the lowest and highest target scores. It should be noted that the specific scores need to be determined based on a large amount of test drive data analysis and data of specific vehicles, which is not limited in this embodiment.

[0069] In the above steps, after obtaining the current values ​​of the multiple dimension parameters, the scores are weighted and summed according to their respective initial weights to obtain a comprehensive score. The comprehensive risk level of the tire is then determined based on the comprehensive score.

[0070] In a feasible specific embodiment of the present invention, the first initialization weight is 0.2, the second initialization weight is 0.05, the third initialization weight is 0.03, and the fourth initialization weight is 0.02. The minimum target score can be 0 points, and the maximum target score can be 100 points. That is, when the current value of the multiple dimension parameters exceeds the corresponding parameter threshold, the initialization weight of the dimension parameter is disregarded, and the current value score of the dimension parameter is directly determined as 100 points; when the current value of the multiple dimension parameters does not exceed the corresponding parameter threshold, the current value score of the multiple dimension parameters is determined as a score between 0 and 100 points, and the score value of each dimension parameter is calculated according to its respective initialization weight. The scores of each dimension parameter are then weighted and summed to obtain a comprehensive score.

[0071] In another feasible embodiment of the present invention, when one of the multiple dimension parameters exceeds its corresponding parameter threshold, the corresponding dimension parameter is scored as 100 points and used as the comprehensive score, thus triggering an alarm. This indicates that the tires are in a serious abnormality, and driving on the road would likely result in a traffic accident. Therefore, the vehicle will be prohibited from starting, and the owner will be reminded to have the tires inspected. In practical applications, the vehicle owner can either contact and schedule an appointment with a nearby 4S dealership, or the owner can proactively contact the dealership.

[0072] refer to Figure 3 , Figure 3 This diagram illustrates a process for determining the current score of multiple dimensions of a tire, as provided in an embodiment of the present invention. Figure 3 As shown:

[0073] When the current value of the tire pressure data is greater than the corresponding parameter threshold, the current score of the tire pressure data is set to the highest target score. When the current value of the tire pressure data is less than or equal to the parameter threshold, the current score of the tire pressure data is set to the value between the minimum target score and the maximum target score.

[0074] When the current value of the tire temperature data is greater than the corresponding parameter threshold, the current score of the tire temperature data is set to the highest target score. When the current value of the tire temperature data is less than or equal to the parameter threshold, the current score of the tire temperature data is set to the value between the minimum target score and the maximum target score.

[0075] When the current value of the number of abnormal tire pressures is greater than the corresponding parameter threshold, the current score of the number of abnormal tire pressures is set to the highest target score. When the current value of the number of abnormal tire pressures is less than or equal to the parameter threshold, the current score of the number of abnormal tire pressures is set to the value between the minimum target score and the maximum target score.

[0076] When the current value of the number of abnormal tire temperatures is greater than the corresponding parameter threshold, the current score of the number of abnormal tire temperatures is set to the highest target score. When the current value of the number of abnormal tire temperatures is less than or equal to the parameter threshold, the current score of the number of abnormal tire temperatures is set to the value between the minimum target score and the maximum target score.

[0077] When the current mileage is greater than the corresponding parameter threshold, the current mileage score is the highest target score; when the current mileage is less than or equal to the parameter threshold, the current mileage score is set to a value between the minimum and maximum target scores.

[0078] When the current value of the driving years is greater than the corresponding parameter threshold, the current driving years score is the highest target score; when the current value of the driving years is less than or equal to the parameter threshold, the current driving years score is set to a value between the minimum target score and the maximum target score.

[0079] If the current value of the driving segment is greater than the corresponding parameter threshold, the current score of the driving segment is the highest target score; if the current value of the driving segment is less than or equal to the parameter threshold, the current score of the driving segment is set to a value between the minimum target score and the maximum target score.

[0080] When the current value of the maintenance record is greater than the corresponding parameter threshold, the current score of the maintenance record is the highest target score; when the current value of the maintenance record is less than or equal to the parameter threshold, the current score of the maintenance record is set to the value between the minimum target score and the maximum target score.

[0081] When the current value of the tire repair record is greater than the corresponding parameter threshold, the current score of the tire repair record is the highest target score; when the current value of the tire repair record is less than or equal to the parameter threshold, the current score of the tire repair record is set to a value between the minimum target score and the maximum target score.

[0082] When the current value of tire wear is greater than the corresponding parameter threshold, the current tire wear score is the highest target score. When the current value of tire wear is less than or equal to the parameter threshold, the current tire wear score is set to a value between the minimum and maximum target scores.

[0083] After obtaining the current scores of the multiple dimension parameters, the current tire comprehensive score is obtained by combining the initial weights corresponding to the current values ​​of each dimension parameter with their respective initial weights and performing a weighted sum. In practical applications, if any of the above-mentioned dimension parameters exceeds a parameter threshold, the comprehensive score is set to the highest target score, and the monitoring of other dimension parameters is stopped, while an alarm is issued simultaneously.

[0084] In another feasible embodiment of the present invention, after the vehicle is powered on, the current values ​​of multiple dimensions of the vehicle's tires can be obtained during the vehicle's self-check. Simultaneously, it can be determined whether the current values ​​of these multiple dimensions have changed. If there is no change, the historical results are displayed; if the data changes, the results need to be recalculated. For example, if the overall test result after powering on is 20 points, indicating that the tires are in good condition and safe to drive, and no monitoring is performed during driving, and after driving 100 kilometers, if at least one of the multiple dimensions changes upon the next start of the vehicle, the result will be recalculated. For example, if the calculated result is 25 points, an intelligent reminder will be given based on this score. However, the entire lifecycle situation also needs to be considered. For example, the number of abnormal tire pressure readings. Since each repair constitutes a new recording cycle, even if the number of abnormal tire pressure readings in a single recording cycle does not exceed the threshold, if the cumulative number of abnormal tire pressure readings within the actual lifecycle exceeds the maximum tolerance value, the overall score needs to be set to 100 points, and an alarm will be given directly. This method can also be applied to other dimensions that require lifecycle monitoring.

[0085] In this embodiment of the invention, the current tire comprehensive score can be the total comprehensive score of the four tires or the comprehensive score of any one of the four tires. If it is the comprehensive score of any one of the four tires, then the comprehensive score of each tire needs to be calculated separately.

[0086] After calculating the tire's overall score in the above steps, it is necessary to determine the tire's current overall risk level based on the overall score.

[0087] When the tire's overall score is in the first target score range, the tire's overall risk level is determined to be in the good performance range.

[0088] When the tire's overall score is in the second target score range, the tire's overall risk level is determined to be in the range of gradually diminishing performance.

[0089] When the overall score of the tire is within the third target score range, the overall risk level of the tire is determined to be in the performance alarm warning range.

[0090] The "good performance" range indicates that the tire is currently within a safe operating range and does not require maintenance; the "gradually deteriorating performance" range indicates that the tire has a problem and its performance is gradually declining, but it does not affect driving; the "performance warning" range indicates that the tire has developed a serious problem that can significantly affect safe driving, and the tire must be inspected and maintained immediately.

[0091] In one feasible embodiment of the present invention, when the vehicle tires are already in the performance warning range, the vehicle will not be able to start, thereby ensuring the safety of the driver.

[0092] In one feasible embodiment of the present invention, the target score range can be 0 to 100 points;

[0093] When the tire's overall score is in the range of 0 to 60, the tire's overall risk level is determined to be in the good performance range.

[0094] When the tire's overall score is in the range of 61 to 80, the tire's overall risk level is determined to be in the range of gradually diminishing performance.

[0095] When the overall score of the tire is in the range of 81 to 100, the overall risk level of the tire is determined to be in the performance warning range.

[0096] It should be noted that in practical applications, when the current score of one of the multiple dimension parameters reaches 100 points, the current score of that dimension parameter can be used as the comprehensive score of the tire, and the scores of other dimension parameters no longer need to be calculated. At this time, it can be determined that the comprehensive risk level of the tire is in the performance warning range, and the vehicle will not be able to start.

[0097] Step 400: Based on the overall risk level of the tire, output a prompt message through the instrument panel.

[0098] In this embodiment of the invention, after determining the overall risk level of the current tire, the risk level can be displayed on the vehicle's dashboard. When the overall risk level is in the good performance range, the dashboard will display a green light; when the overall risk level is in the gradually deteriorating performance range, the dashboard will display a yellow light; and when the overall risk level is in the performance warning range, the dashboard will display a red light.

[0099] In another feasible embodiment, the instrument panel will display a green light when the overall risk level is in the good performance range; a yellow light when the overall risk level is in the gradually deteriorating performance range; and a red light when the overall risk level is in the performance warning range. Simultaneously, while assessing the overall risk level of the tires, the vehicle's self-diagnostic system will transmit specific dimensional parameter scores to the vehicle's central control system, allowing the driver to view the scores for these specific dimensional parameters through the central control system.

[0100] In a preferred embodiment, the vehicle's central control system is connected to a cloud-based intelligent maintenance system. The central control system can alert the driver to problems in a specific dimension based on the scoring of relevant parameters and provide corresponding handling suggestions. Simultaneously, based on the cloud-based intelligent maintenance system, nearby 4S dealerships are notified to proactively contact the driver to inquire whether on-site service or scheduled maintenance services are needed. In practical applications, when a vehicle is in a performance warning zone, the tires may already be in a dangerous condition. Driving under such conditions would significantly increase the probability of a traffic accident. In this case, the vehicle will be unable to start, thus preventing accidents caused by forced driving.

[0101] Another object of the present invention is to provide a tire monitoring system for use in vehicles, wherein, as Figure 4 The diagram shown is a schematic representation of a tire monitoring system according to an embodiment of the present invention. The system includes:

[0102] The acquisition module is used to acquire the current values ​​of multiple dimensional parameters of the vehicle tires;

[0103] The first determining module is used to determine the initial weight of each of the multiple dimension parameters according to the importance level corresponding to each of the multiple dimension parameters; wherein, the higher the importance level, the higher the initial weight of each of the multiple dimension parameters.

[0104] The second determining module is used to determine the overall risk level of the tire based on the current values ​​and initial weights of the multiple dimension parameters.

[0105] The output module is used to output prompt information through the instrument based on the overall risk level of the tire.

[0106] In the system described in this embodiment of the invention, before starting the vehicle, the vehicle is powered on, and the current values ​​of multiple dimensions of the vehicle's tires are acquired by the acquisition module, including at least one of the following: tire pressure data, tire temperature data, number of abnormal tire pressures, number of abnormal tire temperatures, mileage, vehicle age, driving route, maintenance records, and tire wear. Then, the initial weights of each of the multiple dimensions of parameters are determined by the first determination module, followed by the determination of the overall risk level of the tires by the second determination module, and finally, a prompt message is output via the output module.

[0107] The acquisition module includes:

[0108] The first acquisition module is used to acquire the tire pressure data and tire temperature data of the tire;

[0109] The second acquisition module is used to acquire the number of times the tire pressure is abnormal and the number of times the tire temperature is abnormal.

[0110] The third acquisition module is used to acquire the current value of at least one of the following parameters: mileage, years of service, route traveled, maintenance records, tire repair information, and tire wear.

[0111] The first determining module includes:

[0112] The first determining submodule is used to determine the importance level of the multiple dimensional parameters;

[0113] The second determining submodule is used to divide the initial weights of the multiple dimension parameters into a first initial weight, a second initial weight, a third initial weight, and a fourth initial weight according to the importance level corresponding to each of the multiple dimension parameters.

[0114] The second determining module includes:

[0115] The scoring submodule is used to score the current values ​​of the multiple dimension parameters and obtain the current score of each of the multiple dimension parameters.

[0116] The weighted submodule is used to obtain the current tire comprehensive score by weighted summation based on the current score of the current value of each of the multiple dimension parameters and the initial weight of the current value of each of the multiple dimension parameters.

[0117] The second determining submodule is used to determine the overall risk level of the tire based on the current tire comprehensive score.

[0118] The scoring submodule includes:

[0119] The first scoring subunit is used to determine the score of the current value of the dimension parameter that exceeds the parameter threshold as the highest target score when the current value of at least one of the current values ​​of the plurality of dimension parameters exceeds the corresponding parameter threshold.

[0120] The second scoring subunit is used to determine the current value score of the multiple dimension parameters as a score between the lowest target score and the highest target score when the current value of the multiple dimension parameters does not exceed the corresponding parameter threshold.

[0121] The second determining submodule includes:

[0122] The first determining subunit is used to determine that the overall risk level of the tire is in the good performance range when the overall score of the tire is in the first target score range;

[0123] The second determining subunit is used to determine that the tire's overall risk level is in the gradually deteriorating performance range when the tire's overall score is in the second target score range;

[0124] The third determining subunit is used to determine that the overall risk level of the tire is in the performance alarm warning range when the overall score of the tire is in the third target score range.

[0125] Another object of the present invention is to provide a vehicle comprising the tire monitoring system described above.

[0126] The vehicle described above has the same advantages over existing technologies as the aforementioned tire monitoring method and system, which will not be repeated here.

[0127] By employing the technical solution of this invention, the current values ​​of multiple dimensions of vehicle tires are obtained. Then, the current weights of each of the multiple dimensions are determined according to the parameter thresholds corresponding to each of the multiple dimensions.
