Description
Technical Field

Background
The tire is an important component part of the vehicle, in traffic accidents caused by the vehicle, the traffic accidents caused by tire burst account for a large proportion, and particularly for commercial vehicles, the commercial vehicles are forced to run under higher running speed and saturated loading conditions along with the compression of logistics timeliness and logistics cost, so that the probability of tire burst is further increased.
The national standard GB9744 specifies that the truck tires must be run for 47 hours under cumulative load at a corresponding fixed speed in a particular environment without breaking the tires. Accordingly, during the tire development design phase, truck tire products are typically tested for tire failure under this standard, resulting in tire endurance times. Tire products of generally consistent materials, processes, and construction have consistent tire endurance times. And the tire burst probability in the use process of the tire is evaluated according to the duration of the tire obtained in the tire design process, and the limit value of tire burst of the tire product is measured.
In addition, in order to reduce the occurrence rate of tire burst accidents, a tire pressure monitoring system (Tire Pressure Monitoring System, TPMS) is generally introduced into the logistics vehicles at present, so as to measure tire temperature data (or tire temperature data), tire pressure data (or tire pressure data), tire load data and the like through sensors installed on the tires, and further perform tire burst early warning on a fleet or a driver according to the tire temperature data, the tire pressure data and the like and corresponding thresholds.
However, in the actual fleet tire management process, most tires often have a puncture accident when the tire temperature or the tire pressure threshold set by the TPMS has not been reached. Therefore, how to more accurately predict tire burst is a problem to be solved.

Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, a flowchart for implementing a tire burst prediction method provided by an embodiment of the present invention is shown, and details are as follows:
in step 101, during use of the tire, key factor data affecting a tire puncture and additional factor data affecting the tire puncture in combination with the key factor data are obtained.
In this embodiment, considering that there are many factors affecting tire burst, for example, burst caused by overload, burst caused by overspeed, burst caused by too high or too low tire pressure, etc., it is not enough to predict tire burst by simply using certain factor data, and the effect of directly combining various factor data to predict tire burst is also not ideal. Therefore, it is considered that a factor is used as a key factor and a factor having a synergistic effect with the factor as a key factor is used as an additional factor of the key factor, so that tire puncture prediction is performed based on the key factor data affecting tire puncture and the additional factor data corresponding to the key factor data.
For example, various factor data of the same type of tire from the start of use to the blowout may be collected, such as load data, tire temperature data, tire pressure data, speed data, and the like of the same type of tire from the start of use to the blowout. And then taking one of the factor data as key factor data, inputting the key factor data and other factor data into a preset model for training so as to determine an additional factor with a synergistic effect with the key factor. Or the additional factors with the synergistic effect with the key factors can be determined empirically, so that the subsequent tire burst prediction can be more accurately performed based on the key factor data of the tire and the additional factor data corresponding to the key factor data.
Alternatively, the key factor data trained by the preset model or empirically determined may include at least one of loading factor data, tire temperature factor data, high tire pressure factor data, low tire pressure factor data, and speed factor data. Including, for example, loading factor data, tire temperature factor data, high tire pressure factor data, low tire pressure factor data, and speed factor data. Or only comprises loading factor data, tire temperature factor data and high tire pressure factor data.
Each item of factor data affecting tire burst is used as key factor data, and additional factor data corresponding to the key factor data is determined, so that tire burst prediction can be performed more accurately when a certain item of key factor data and the additional factor data corresponding to the key factor data meet the corresponding conditions of tire burst.
By way of example, training through a pre-set model or empirically may determine: when the key factor data is load factor data, the additional factor data that affects the tire burst together with the key factor data may include tire temperature factor data, high tire pressure factor data, and speed factor data.
When the key factor data is tire temperature factor data, the additional factor data that affects tire burst together with the key factor data may include load factor data, high tire pressure factor data, and speed factor data.
When the key factor data is high tire pressure factor data, the additional factor data that affects tire burst together with the key factor data may include load factor data, tire temperature factor data, and speed factor data.
When the key factor data is speed factor data, the additional factor data that affects the tire burst together with the key factor data may include load factor data, tire temperature factor data, and high tire pressure factor data.
When the key factor data is low tire pressure factor data, the additional factor data that affects tire puncture in conjunction with the key factor data may include loading factor data.
The comparison of damaged tires in low tire pressure is considered, so that when the key factor data is low tire pressure factor data, tire burst prediction can be performed only by combining load factor data with strong synergism with the tire pressure factor. That is, only the loading factor data is used as the additional factor data of the low tire pressure factor data.
In step 102, statistics of usage data of the tire when the key factor data meets a first threshold and the additional factor data meets a second threshold.
The first threshold value is a value representing that the tire is in a fatigue working condition under the key factors, and the second threshold value is a value representing that the tire is in the fatigue working condition under the additional factors corresponding to the key factors.
In this embodiment, considering that the tire is more likely to be burst when the tire is in the fatigue working condition, the value of the tire in the fatigue working condition under the key factor is obtained as the first threshold corresponding to the key factor, and the value of the tire in the fatigue working condition under the additional factor corresponding to the key factor is obtained as the second threshold corresponding to the additional factor, so that the use data of the tire when the key factor data of the tire meets the first threshold and the additional factor data meets the second threshold is counted, so as to measure the use condition of the tire in the fatigue working condition, and further, whether the tire is burst is predicted more accurately based on the use condition of the tire in the fatigue working condition.
For example, if the tire is more likely to cause a puncture when the load of the tire is greater than 110% of the standard load, and at the same time, the tire is more likely to cause a puncture when the tire temperature is greater than 70 ℃ and the tire pressure is greater than 1150kpa, and the speed is greater than 70km/h, it may be determined that when the key factor data is the load factor data, the first threshold value corresponding to the key factor is 110% of the standard load, and the second threshold values corresponding to the key factors are 70 ℃ and 1150kpa and 70km/h, respectively.
For example, if the tire is more likely to cause a puncture when the tire temperature is > 80 ℃, and at the same time, the tire is more likely to cause a puncture when the load is > 80%, the tire pressure is > 1150kpa, and the speed is > 80km/h, it may be determined that when the key factor data is the tire temperature factor data, the first threshold value corresponding to the key factor is 80 ℃, and the second threshold values of the additional factors corresponding to the key factors are respectively 80% standard load, 1150kpa, and 80km/h.
For example, if the tire is more likely to cause a puncture when the high tire pressure is greater than 1250kpa, and at the same time, the tire is more likely to cause a puncture when the load is greater than 80%, the tire temperature is greater than 75 ℃, and the speed is greater than 80km/h, it may be determined that when the key factor data is the high tire pressure factor data, the first threshold value corresponding to the key factor is 1250kpa, and the second threshold values corresponding to the additional factors are 80% standard load, 75 ℃ and 80km/h, respectively.
For example, if the tire is more likely to cause a puncture when the speed of the tire is greater than 80km/h, and at the same time, the tire is more likely to cause a puncture when the load is greater than 80%, the tire temperature is greater than 65 ℃, and the high tire pressure is greater than 1150kpa, it may be determined that when the key factor data is the speed factor data, the first threshold value corresponding to the key factor is 80km/h, and the second threshold values corresponding to the additional factors are 80% standard load, 65 ℃ and 1150kpa, respectively.
For example, if the tire is more likely to cause a blowout when the low tire pressure is less than 600kpa, and at the same time, the tire is more likely to cause a blowout when the load is greater than 80%, it may be determined that the first threshold value corresponding to the key factor is 600kpa and the second threshold value corresponding to the additional factor is 80% of the standard load when the key factor data is the low tire pressure factor data.
When the key factor and the additional factor corresponding to the key factor are other factors, the determination process of the first threshold of the key factor and the second threshold of the corresponding additional factor is similar to the above process, and will not be described herein.
On this basis, because the tire burst is caused by the use of the tire under the action of factors of corresponding high load, high temperature and high pressure, the statistics of the usage data of the tire when the key factor data meets a first threshold value and the additional factor data meets a second threshold value is needed to predict the tire burst. For example, the statistical load is more than 110% of standard load, and the tire temperature is more than 70 ℃, the tire pressure is more than 1150kpa, and the speed is more than 70km/h, so as to predict the tire burst.
Wherein the usage data of the tire may characterize a usage experience of the tire. For example, the usage data of the tire may include usage mileage data and/or usage time data of the tire. And counting the accumulated use condition of the tire under the action of factors of corresponding high load, high temperature and high pressure through at least one of the use mileage data and the use time data of the tire.
For example, the accumulated use mileage data and/or the accumulated use time data of the tire are counted when the load is more than 110% of the standard load, and the tire temperature is more than 70 ℃, the tire pressure is more than 1150kpa, and the speed is more than 70 km/h.
In step 103, equivalent fatigue usage data for the tire under the key factors is calculated from the usage data.
In step 104, a puncture prediction is performed for the tire based on the equivalent fatigue usage data.
In combination with the description in step 102, due to the difference of the corresponding first threshold value or the second threshold value when the factor affecting the tire burst is taken as the key factor or the additional factor, and the difference of the corresponding second threshold value when the additional factor is taken as the additional factor of different key factors, the usage data of the tire when the key factor data meets the first threshold value and the corresponding additional factor data meets the second threshold value is counted, so as to calculate the equivalent fatigue usage data of the tire under the key factor according to the usage data counted when the key factor and the corresponding additional factor meet the condition, and perform the tire burst prediction on the tire according to the equivalent fatigue usage data of the tire under the key factor, thereby obtaining a more accurate tire burst prediction result.
According to the embodiment of the invention, the key factor data influencing tire burst and the additional factor data influencing tire burst together with the key factor data are obtained in the use process of the tire, so that the use data of the tire when the key factor data meets a first threshold value and the additional factor data meets a second threshold value is counted, the use condition of the tire under the fatigue working condition is measured by the use data of the tire when the key factor data meets the first threshold value and the additional factor data meets the second threshold value, and the equivalent fatigue use data of the tire under the corresponding key factor and the corresponding additional factor are obtained, so that the tire burst is predicted more accurately according to the equivalent fatigue use data, the early prevention of the tire burst of a commercial vehicle is facilitated, and the traffic accidents and the property loss are reduced.
Optionally, for the purpose of calculating the equivalent fatigue usage data more accurately later to more accurately perform tire burst prediction, the usage data of the tire when the statistical key factor data satisfies the first threshold and the additional factor data satisfies the second threshold may include: dividing the key factor data into a plurality of subintervals, and counting the usage data of the tire in each subinterval when the key factor data meets a first threshold value and the additional factor data meets a second threshold value.
For example, as shown in table 1, for example, the tire temperature factor data, the tire pressure factor data, the speed factor data, and the load factor data may be divided into a plurality of subintervals according to the set interval values, and the corresponding levels of the subintervals may be determined, so as to facilitate accurate statistics of usage data of the tire when the critical factor data satisfies the first threshold value and the additional factor data satisfies the second threshold value.

As shown in table 1, the levels corresponding to the subintervals divided for each key factor data may be ordered in order from small to large or from large to small, which is not limited in this embodiment.
In this embodiment, considering that the probability of tire puncture is different when the key factor data falls in each subinterval, in order to predict tire puncture more accurately, the usage data of the tire at each subinterval is counted when the key factor data satisfies the first threshold and the additional factor data satisfies the second threshold.
Alternatively, calculating equivalent fatigue usage data for the tire under the key factors from the usage data may include: and acquiring fatigue weights corresponding to the key factor data in each subinterval, and calculating equivalent fatigue use data of the tire under the key factors according to the fatigue weights corresponding to the key factor data in each subinterval and the use data of the tire when the key factor data is in each subinterval.
In this embodiment, on the basis of dividing the key factor data into a plurality of subintervals, according to the possibility that the tire bursts when the key factor data falls in different subintervals, the fatigue weight corresponding to each subinterval of the key factor data is obtained, so that the equivalent fatigue use data of the tire under the key factor can be measured more accurately according to the fatigue weight corresponding to each subinterval of the key factor data and the use data of the tire when the key factor data is in each subinterval.
For example, the key factor data is divided into several sub-intervals and the fatigue weights of the key factor data corresponding to the respective sub-intervals may be determined by model training. As shown in table 1, for example, when the key factor data is load factor data, the corresponding first threshold may be 110% of the standard load (or nominal load), and the data with load factor data > 110% of the nominal load may be divided into 10 subintervals. When the key factor data is speed factor data, the corresponding first threshold value can be 100km/h, and the data of the speed factor data > 100km/h can be divided into 9 subintervals. When the key factor data is high tire pressure factor data, the corresponding first threshold value may be 1250kpa, and the data of the high tire pressure factor data > 1250kpa may be divided into 4 subintervals.
