It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application.

[0024] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0025] A common method for determining the remaining service life of a tire in the prior art is to collect tire images and then further analyze the tire wear condition in combination with the tire temperature, or to determine the tire wear condition by analyzing the tire noise caused by the tire against the road surface, and further determine the tire life based on the acquired wear condition.

[0026] In the prior art, the technical means of using image analysis technology to determine the tire wear condition and thus the remaining service life of the tire has the disadvantages of high analysis cost and complex system.

[0027] The technical disadvantage of analyzing tire wear through tire noise is that it is too dependent on road conditions and is not very accurate.

[0028] Based on this, the embodiments of the present application provide a method, device, electronic device and storage medium for detecting the remaining service life of a tire, which jointly determines the remaining service life of the tire by a gas concentration sensor and a thermal sensor, thereby reducing the calculation complexity and accuracy of the remaining service life of the tire, as follows:

[0029] See also Figure 1 , Figure 1 FIG. 1 is a flow chart showing a method for detecting the remaining service life of a tire provided in an embodiment of the present application. Figure 1As shown, the method provided in the embodiment of the present application is integrated in a vehicle controller, the vehicle controller is connected to a signal receiver, the signal receiver pre-establishes communication with a tire pressure sensor, a gas concentration sensor and a thermistor sensor in a tire currently in use by the vehicle, and the vehicle controller is also connected to a central control display, specifically, comprising the following steps:

[0030] S100: Obtaining a target volatile organic compound gas concentration in a tire currently in use of the vehicle collected by a gas concentration sensor at a current moment.

[0031] The tire comprises an inner tube and an outer tube, and the gas concentration sensor is installed in the inner tube.

[0032] S200: Obtain a target average tire temperature of a currently used tire of the vehicle collected by a thermal sensor within a historical time period.

[0033] The thermal sensor is installed in the tire inner tube.

[0034] S300: Determine a target gas concentration variation curve at a target tire average temperature according to tire data corresponding to a currently used tire of the vehicle.

[0035] The gas concentration variation curve indicates the mapping relationship between the volatile organic compound gas concentration in the tire inner tube and the service aging age.

[0036] S400: Determine the remaining service life of the tire at the current moment according to the target volatile organic compound gas concentration, the target gas concentration variation curve and the given tire service life limit, and send the remaining service life of the tire to the central control display for display.

[0037] In step S100, the gas concentration sensor installed in the tire currently in use of the vehicle can continuously collect the volatile organic gas concentration in the inner tube according to a given collection frequency after completing initialization, and the collected volatile organic gas concentration is sent to the signal receiver. The present application extracts the volatile organic gas concentration at the current moment from the signal receiver.

[0038] In step S200, the present application receives and records the tire temperature transmitted by the thermistor through a signal receiver, and calculates the target tire average temperature corresponding to the current moment based on a preset historical time period (for example, within the past month based on the current moment).

[0039] In step S300, the tire data includes the tire model. Specifically, the gas concentration change curves corresponding to different models of tires at different average tire temperatures are different. Therefore, the present application needs to first determine which gas concentration change curve to use as the target gas concentration change curve for the subsequent calculation of the remaining tire aging life based on the tire model currently used by the vehicle and the target average tire temperature collected at the current moment.

[0040] In step S400, after determining the target gas concentration change curve corresponding to the current moment, the remaining tire service life at the current moment can be further determined according to the target volatile organic compound gas concentration and the given tire service life limit and sent to the central control display for real-time display.

[0041] The method provided in the present application is mainly aimed at tires with an inner tube and an outer tube structure. In steps S100 to S400, the method provided in the present application calculates the remaining service life of the tire according to a preset calculation frequency. Specifically, the present application uses a gas concentration sensor to record the rising process of the gas concentration of the inner tube, and further combines it with a predetermined gas concentration change curve to determine the remaining service life of the tire at the current moment. The method is mainly based on the fact that the VOCs (Volatile Organic Compounds) gases emitted by the tire during the continuous aging process are different. Based on this, the concentration change curve of the volatile organic compound gas in the inner tube can be pre-stated to determine the aging age of the tire and further determine the remaining service life of the tire. In this process, due to the obvious change in the concentration of volatile organic compound gases in the severely worn tire, the present application determines the remaining service life of the tire by combining a gas concentration sensor with a thermal sensor to reduce the calculation complexity and accuracy of the remaining service life of the tire.

[0042] In a preferred embodiment, the remaining useful life of the tire is determined by:

[0043] According to the outer tire model currently used by the vehicle, determine the target gas concentration change curve at the target average tire temperature. According to the target gas concentration change curve, determine the target usage aging age corresponding to the target volatile organic compound gas concentration. According to the given tire service life limit and the target usage aging age, determine the remaining service life of the tire.

[0044] Specifically, for different outer tire models, the corresponding gas concentration change curves at the same average tire temperature are different. For the same outer tire model, affected by the average tire temperature, the corresponding gas concentration change curves at different average tire temperatures are also different. Therefore, in the present application, the target curve data packet corresponding to the outer tire model currently used by the vehicle is first retrieved. The curve data packet stores multiple gas concentration change curves of the same outer tire model at different average tire temperatures. After determining the target curve data packet, the target gas concentration change curve is further determined according to the target average tire temperature. Then, the target usage aging age of the tires currently used by the vehicle at the current moment is further determined according to the target gas concentration change curve and the target volatile organic compound gas concentration.

[0045] In a preferred embodiment, before determining the target gas concentration variation curve, the method further includes:

[0046] Real-time detection is performed to determine whether a tire replacement signal is received. The tire replacement signal is sent from the cloud. If a tire replacement signal is detected, the tire data corresponding to the target tire replaced by the vehicle is retrieved from the cloud, and the tire data corresponding to the target tire is used to update the tire data of the currently used tire.

[0047] Specifically, in the present application, considering the replacement of the tire outer shell, each replacement requires the calculation of the remaining service life of the tire to be restarted. Therefore, each time the tire outer shell is replaced in the present application, the outer shell data corresponding to the tire outer shell needs to be updated. Specifically, each time the tire outer shell is replaced, the user scans the identification mark on the target outer shell replaced by the vehicle through the target application service in the mobile terminal and generates a tire replacement signal. At the same time, the identification mark and the outer shell replacement signal will be sent to the cloud at the same time. In the method provided by the present application, the outer shell replacement signal sent by the cloud (carrying the identification mark corresponding to the replaced outer shell) is detected in real time. When the outer shell replacement signal is received, the corresponding outer shell data is retrieved from the cloud according to the identification mark on the target outer shell replaced by the vehicle and updated to the outer shell data of the currently used outer shell. In this way, the corresponding target gas concentration change curve can be re-determined using the updated outer shell data when the outer shell is replaced, and the calculation of the remaining service life of the tire corresponding to the replaced outer shell is restarted.

[0048] In a preferred embodiment, the target usage aging age is determined by:

[0049] Receive the current tire pressure collection value and the previous tire pressure collection value of the tire currently in use of the vehicle collected by the tire pressure sensor, the current tire pressure collection value is the tire pressure collection value corresponding to the current moment, and the previous tire pressure collection value is the tire pressure collection value corresponding to the previous moment, the tire pressure sensor is installed in the inner tube, calculate the difference between the current tire pressure collection value and the previous tire pressure collection value and determine it as the tire pressure change value, determine whether the tire pressure change value is within the target tire pressure change range, the target tire pressure change range is the inflation tire pressure change range or the deflation tire pressure change range, if the tire pressure change value is within the target tire pressure change range, then directly use the target usage aging age calculated at the previous moment as the target usage aging age at the current moment, if the tire pressure change value is within the given normal tire pressure change range, then bring the target volatile organic compound gas concentration into the target gas concentration change curve to obtain the target usage aging age at the current moment.

[0050] In a specific example, the process of determining the target usage aging age corresponding to the tire currently in use by the vehicle at the current moment needs to consider the process of tire inflation and deflation performed to maintain a constant tire internal pressure. During the tire inflation and deflation process, the tire pressure change values ​​corresponding to adjacent moments are obviously different from the tire pressure change values ​​at adjacent moments when the tire is not inflated or deflated. The present application uses the difference between the two to pre-set the target tire pressure change range at adjacent moments during the inflation and deflation process and the given normal tire pressure change range when the tire is not inflated or deflated (i.e., normal state). The state of the tire currently in use by the vehicle (including inflation, deflation and normal state) is further determined through the tire pressure change value between the current moment and the previous moment. According to the different states of the tire currently in use by the vehicle, the target usage aging age corresponding to the tire currently in use by the vehicle at the current moment needs to be determined in different ways.

[0051] Specifically, when the tire pressure change value is within the target tire pressure change range, it means that the vehicle's current tire is in an inflated or deflated state. In this state, the collected target volatile organic compound gas concentration is affected by the inflation or deflation state and no longer conforms to the determined target gas concentration change curve. At this time, at the current moment, it is necessary to use the target usage aging age calculated at the previous moment as the basis, and it is necessary to recalculate and update the gas concentration change curve corresponding to the currently used outer tire model at the target average tire temperature for subsequent use.

[0052] If the tire pressure change value is within the given normal tire pressure change range, the target gas concentration change curve is still taken as the basis, and the target volatile organic compound gas concentration is substituted into the target gas concentration change curve to obtain the target usage aging age of the vehicle's currently used tires at the current moment.

[0053] In a preferred embodiment, the method provided by the present application further includes:

[0054] If the tire pressure change value is within the target tire pressure change range, the slope corresponding to the target gas concentration change curve is extracted, and the target volatile organic compound gas concentration and the target usage aging age calculated at the previous moment are used as the initial change point. Combined with the slope corresponding to the target gas concentration change curve, the gas concentration change curve of the vehicle's current tires at the target average tire temperature is recreated and updated.

[0055] For details, please refer to Figure 2 , Figure 2 FIG. 1 is a schematic diagram showing a gas concentration change curve updating process provided by an embodiment of the present application. Figure 2 In the coordinate system shown, the abscissa represents the volatile organic compound gas concentration F, and the ordinate represents the tire's service aging age x, wherein, assuming that L1 represents the target gas concentration change curve used at the previous moment t0, and the target volatile organic compound gas concentration measured at the previous moment t0 is f0, then for the previous moment t0, f0 is substituted into L1 to determine the target service aging age corresponding to the previous moment as x0, and the corresponding target volatile organic compound gas concentration is detected at the current moment t1 as f1, and it is determined that the tire pressure change value corresponding to the previous moment t0 and the current moment t1 is within the target tire pressure change range, then at this time, the target service aging age corresponding to the current moment t1 is directly determined as the target service aging age calculated at the previous moment t0 as x0, and further, the gas concentration change curve of the tire currently used by the vehicle at the target tire average temperature is updated.

[0056] Specifically, Figure 2 , taking (f1, x0) as the initial change point of the updated gas concentration change curve, retaining the corresponding slope of L1, the updated gas concentration change curve L2 of the vehicle's currently used tire at the target tire average temperature can be obtained.

[0057] In a preferred embodiment, the remaining useful life of the tire is determined by:

[0058] Retrieve the production date of the currently used outer tire, determine the target static depreciation ratio, static aging age weight and usage aging age weight corresponding to the tire currently used by the vehicle according to the currently used outer tire model, determine the target static aging age of the currently used outer tire according to the time difference between the production date and the replacement date and the target static depreciation ratio, weight the target static aging age and the target usage aging age using the static aging age weight and the usage aging age weight to determine the target tire aging age, and determine the difference between the given tire service life limit and the target tire aging age as the remaining tire service life of the tire currently used by the vehicle at the current moment.

[0059] In the present application, there is static aging of the tire from production to commissioning. In the present application, there is a certain relationship between the static aging age and the time difference between the production date and the replacement date of the tire. The relationship is defined as the static depreciation ratio. The static depreciation ratio, static aging age weight and usage aging age weight corresponding to different tire models are all different.

[0060] In addition, in the present application, the static depreciation ratio, static aging age weight and usage aging age weight corresponding to different tire models are given in advance.

[0061] In a preferred embodiment, the method provided by the present application further includes:

[0062] The remaining service life of the tire is compared with the remaining service life threshold of the tire. If the remaining service life of the tire reaches the remaining service life threshold of the tire, a tire life warning prompt is generated and sent to the central control display.

[0063] Specifically, the tire life warning can be set according to actual needs, such as generating a text prompt message (such as a tire change reminder) or displaying the remaining tire life in different colors as the remaining tire life shortens compared to the remaining tire life threshold, such as gradually deepening the same color or displaying different colors. No specific restrictions are made here.

[0065] ① This application is simple to implement and cost-controllable.

[0066] ②This application method can be applied to independent vehicles without removing the tires.

[0067] ③ Accurate measurement. Since the concentration of volatile organic compounds in severely worn tires changes significantly, the accuracy of monitoring using volatile organic compound gas concentration is guaranteed.
