Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0060] In order to enable those skilled in the art to better understand the present application, the application scenarios involved in the present application are first briefly described.
[0061] As a vehicle drives, its tires experience a certain degree of wear. In related technologies, users can only visually inspect the extent of tire wear, but many users are unable to determine whether a tire needs replacement. Visual inspection is extremely inaccurate, causing significant inconvenience to users. Furthermore, continued use of severely worn tires poses significant safety risks.
[0062] Specifically, currently, the decision to replace a vehicle's tires is largely left to the user. This determination relies on visually assessing whether the internal grooves have reached a certain level of wear. However, this determination method is based on simple instructions, leaving users vulnerable to inexperience, the need for professional assistance, or even the need for tire salespeople to manipulate them. Consequently, current tire wear assessment methods are significantly inconvenient for users, and continued use of severely worn tires poses significant safety risks.
[0063] In order to solve the above problems, the embodiments of the present application provide a vehicle tire status reminder method, device, program product, medium and vehicle, which can at least to a certain extent remind the vehicle tire status, improve the accuracy of tire wear detection, and at the same time improve the user convenience and reduce safety hazards.
[0064] Reference Figure 1, shows a flow chart of a vehicle tire status reminder method in an embodiment of the present application. The vehicle tire status reminder method can be executed by a device with computing and processing capabilities. For example, it can be executed by a vehicle controller, which is not limited in the present application.
[0065] Reference Figure 1 As shown, according to the first aspect of an embodiment of the present application, a vehicle tire status reminder method is provided for a vehicle. The vehicle of the present application includes tires, the number of which is determined by the type of vehicle, and a typical vehicle has four tires. A tire processing unit and at least two detection units are provided on the tire. The detection unit is connected to the tire processing unit. The detection unit is used to detect the wear of the tire, obtain a detection result, and send the detection result to the tire processing unit. The tire processing unit can be a microprocessor chip embedded in the middle of the tire, and the detection unit can be a detection element for detecting the wear of the tire, such as a resistance meter for measuring resistance, an instrument for measuring thickness or friction, etc. At least two of the detection units are not located at one position on the tire. In one embodiment, the at least two detection units can be evenly distributed at various angles of the tire. For example, when there are two detection units, the two detection units are distributed at both ends of the diagonal of the tire. If there are four detection units, the four detection units can be distributed at ninety degrees on the tire.
[0066] The vehicle tire status reminder method of the present application includes at least steps 110 to 130, which are described in detail as follows:
[0067] Step 110: Acquire a detection result through the tire processing unit, where the detection result includes at least two level parameters detected by at least two detection units.
[0068] The tire processing unit of the present application can be a microprocessor chip connected to the vehicle controller by wire or wirelessly, and is provided for each tire. The tire processing unit is connected to the detection unit and receives detection results sent by the detection unit, which include at least two level parameters detected by at least two detection units.
[0069] The detection unit can be an instrument for measuring resistance, such as a sliding rheostat, and the corresponding level parameter is the resistance value; the detection unit can also be other parameters for measuring friction changes, and the corresponding level parameter can be the friction change value, etc.
[0070] In one embodiment of the present application, the detection unit of the present application can verify the degree of tire wear before the tire leaves the factory. Therefore, if there are two detection units, the two initial detection values detected by the two sensors corresponding to the detection units must be verified on the tire before leaving the factory. In addition, this verification is continuous during the rolling process. When the vehicle is stationary, there may be differences in the tire itself due to gravity. When the vehicle is running, the error is very small. Therefore, the solution of the present application can verify the tire wear conditions when the vehicle is stationary and when running, which is convenient to use.
[0071] Step 120: When the maximum difference between at least two level parameters is less than or equal to a first threshold, determine that the current detection result is valid.
[0072] The present application determines that the current detection result is valid when the maximum difference between at least two level parameters is less than or equal to a first threshold. In real-world situations, vehicles are constantly in motion. As a result of this movement, the vehicle may be parked on uneven roads or sandy ground, or a tire may be engulfed by small stones, all of which can lead to inaccurate detection results. Therefore, to avoid this situation, the present application introduces at least two detection units, and only determines that the current detection result is valid when the maximum difference between at least two level parameters is less than or equal to the first threshold. In other words, the present application expects that the at least two level parameters detected by the at least two detection units of the tire are completely consistent. Of course, due to varying degrees of wear in different locations on the tire, complete consistency cannot be guaranteed. The present application introduces a first threshold to mitigate errors caused by tire characteristics or usage habits. When using a resistance meter as the detection unit, the first threshold can be 0.1 milliohms. Specifically, the current detection result is determined to be valid if the difference between the maximum and minimum resistance values of the at least two resistance values detected by the at least two detection units does not exceed 0.1 milliohms.
[0073] Step 130: When the maximum value of the at least two level parameters is greater than or equal to the second threshold, a first reminder signal is issued, where the first reminder signal is used to prompt the user to change the tire.
[0074] After determining that the current detection result is valid through step 120, step 130 can be performed to further determine whether the maximum value of at least two level parameters is greater than or equal to the second threshold. If so, a first reminder signal is issued, which is used to prompt the user to change the tire.
[0075] Step 130 of the present application determines whether the current wear exceeds a set second threshold. This second threshold is set based on tire scrapping. Specifically, when the wear level of the vehicle tire reaches the second threshold, continued driving may pose a significant safety risk, such as a tire blowout. The second threshold can be set using industry standards for tire scrapping.
[0076] In step 130 of the present application, when it is determined that the maximum value of at least two level parameters is greater than or equal to a second threshold, a first reminder signal is issued. The first reminder signal is used to prompt the user to change tires. This can effectively remind the user to change tires. Using the maximum value of at least two level parameters for judgment is also intended to further reduce risk. Because the maximum value of at least two level parameters is greater than or equal to the second threshold, a warning can be issued in advance to avoid dangerous situations.
[0077] Based on the technical solution proposed in the present application, the present application provides a tire processing unit and at least two detection units on the tire, and determines that the current detection result is valid when the maximum difference between at least two level parameters is less than or equal to a first threshold value. After the result is valid, a first reminder signal is issued when the maximum value of the at least two level parameters is greater than or equal to a second threshold value. The first reminder signal is used to prompt the user to replace the tire. Since the present application uses at least two detection units to detect the level parameters of the tire, and determines whether the maximum difference between at least two level parameters is less than or equal to the first threshold value, if the maximum difference between the two level parameters is less than or equal to the first threshold value, it indicates that the current detection result of the tire is valid. The method of the present application can more accurately detect the level parameters of the tire, avoiding the problem of inaccurate detection results caused by the surrounding environment of the tire, such as the tire being stuck in stones or sand. Therefore, the solution of the present application improves the accuracy of tire wear detection. At the same time, since it can automatically detect and issue the first reminder signal, the present application also improves the convenience of user use and reduces safety hazards to a certain extent.
[0078] In order to make those skilled in the art better understand this application, Figure 2 , continue to explain other solutions of this application.
[0079] See also Figure 2 , shows a detailed flow chart of the vehicle tire status reminder method in an embodiment of the present application. In some embodiments of the present application, based on the above solution, the method of the present application further includes steps 210-220.
[0080] Step 210: When the maximum difference between at least two level parameters is greater than a first threshold, determine that the current detection result is invalid.
[0081] In this application, if the maximum difference between at least two level parameters is greater than the first threshold, it means that the data detected by each detection unit is inconsistent. This may be due to the surrounding environment of the tire, such as being stuck with stones or being in sand, which causes the data detected by each detection unit to have large discrepancies.
[0082] Step 220: Sending a second reminder signal, which is used to remind the user that the current detection result is inaccurate and to check the surrounding conditions of the tire.
[0083] If the situation in step 210 occurs, a second reminder signal is issued to remind the user that the current test result is inaccurate and to check the surrounding conditions of the tire. After receiving the reminder, the user can check the tire condition and drive the car to an unaffected environment before performing tire replacement test.
[0084] The solution of this application can determine the current test result by comparing at least two level parameters, avoiding detection errors caused by stones stuck in the vehicle tire or in special environments, thereby improving detection accuracy. Moreover, if the test result is inaccurate, the user can be reminded to check the surrounding conditions of the tire. After checking, the user can drive the vehicle to an unaffected environment for further testing, thereby improving the accuracy of vehicle tire wear detection.
[0085] In order to enable those skilled in the art to better understand the present application, other solutions of the present application will be further described.
[0086] In some embodiments of the present application, based on the aforementioned solution, the vehicle includes a dashboard or a display, and the method of the present application further includes:
[0087] When the maximum value of the at least two level parameters is less than the second threshold, a signal indicating that the tire is normal is sent to the instrument panel or the display.
[0088] The vehicle of the present application is equipped with a dashboard or display. When the maximum value of at least two level parameters is less than the second threshold value, it means that the tire is in good wear condition and does not need to be replaced. At this time, a signal indicating that the tire is normal can be sent to the dashboard or display.
[0089] This application uses the dashboard or display to remind users of the tire status, providing users with a good user experience. Users can clearly obtain the status of each tire through the dashboard or display and use it with peace of mind.
[0090] In order to make those skilled in the art better understand this application, Figure 3 , continue to explain other solutions of this application.
[0091] See also Figure 3 , shows a detailed flow chart of the vehicle tire status reminder method in an embodiment of the present application.
[0092] In some embodiments of the present application, based on the aforementioned solution, the method of the present application further includes steps 310 to 330.
[0093] Step 310: Obtain the initial use time of the tire.
[0094] The tire's initial use time is the time the tire begins to be used after being installed. The vehicle's processor can obtain this time from the memory, or it can be obtained from the user, or the user can manually enter this time.
[0095] Step 320: Obtain the current time, and subtract the starting usage time from the current time to obtain the tire usage time.
[0096] The processor can directly obtain the current time through the Internet, and then subtract the starting usage time from the current time to obtain the tire usage time.
[0097] Step 330: When the tire usage time is greater than or equal to a first preset time, a first reminder signal is issued.
[0098] The first preset time duration is the allowable service life of the tire. If the usage time exceeds this time duration, it is recommended to replace the tire, otherwise there is a greater risk. This application issues a first reminder signal when the tire usage time is equal to or greater than the first preset time duration. The first reminder signal is the same as that in step 130, i.e., it is used to prompt the user to replace the tire. This can effectively remind the user to replace the tire.
[0099] Through this embodiment of the present application, not only can the tire status of the vehicle be reminded according to the degree of tire wear, but the tire status of the vehicle can also be reminded according to the length of time the tire has been used, further improving the safety factor.
[0100] In some embodiments of the present application, based on the aforementioned solution, the vehicle includes a speaker, a dashboard, or a display, and issues a first reminder signal, including:
[0101] an audible warning signal through a loudspeaker; or
[0102] Signalled by an icon on the instrument panel; or
[0103] A visual reminder signal is issued via the display.
[0104] The first reminder signal of the present application can be issued via a speaker, instrument panel, or display. The speaker can issue an audible reminder signal, such as a voice message such as "The left tire is severely worn, please replace it," to prompt the user to replace it. The instrument panel can issue an icon display signal, such as a flashing icon indicating severe left tire wear, to prompt the user to replace it. The display can issue a video reminder signal to prompt the user that the left tire needs to be replaced. The video reminder signal can also include a video of the tire replacement, further enhancing the user experience.
[0105] Among them, this application can also use speakers, dashboards and displays to issue reminders at the same time to prevent users from missing some information.
[0106] This application reminds users through the speakers, dashboard or display configured on the vehicle, so that users can clearly know the wear status of each tire of the vehicle, thereby facilitating tire replacement and improving the user experience.
[0107] In order to make those skilled in the art better understand this application, Figure 4 , continue to explain other solutions of this application.
[0108] See also Figure 4 , shows a detailed flow chart of the vehicle tire status reminder method in an embodiment of the present application.
[0109] In some embodiments of the present application, based on the aforementioned solution, the detection unit includes a sliding rheostat, the sliding rheostat includes a fixed end and a movable end, and the level parameter includes the resistance value of the tire; in step 110 of the present application, the method for obtaining the detection result through the tire processing unit includes steps 410-420:
[0110] Step 410: Sending a collection signal to the tire processing unit. The collection signal is used to drive the tire processing unit to send a detection signal to the active end of the sliding rheostat. The detection signal is used to drive the active end to move. The tire processing unit is used to record the moving distance of the active end.
[0111] The detection unit of this application includes a sliding rheostat, which includes a fixed end and a movable end. The movable end moves as the tire skin thins, while the fixed end remains unchanged. When the sliding end moves due to tire thinning, the resistance of the contact with the fixed end changes, causing a change in resistance value, which is transmitted to the tire processing unit. The change in resistance value is linearly related to the sliding distance, which is more intuitive.
[0112] Therefore, based on the characteristics of a sliding rheostat, this application uses the sliding rheostat as a detection unit. A collection signal is sent to the tire processing unit, which drives the tire processing unit to send a detection signal to the active end of the sliding rheostat. The detection signal drives the active end to move, and the tire processing unit records the movement distance of the active end. Once the tire processing unit has recorded the movement distance of the active end, step 420 can be performed.
[0113] Step 420: The tire processing unit obtains the movement distance, and determines the resistance value of the tire according to the movement distance.
[0114] The active distance is obtained through the tire processing unit, and then the corresponding sliding distance and tire resistance value can be mapped one by one according to a pre-set mapping table to find the tire resistance value corresponding to the active distance, and the detection result can be determined.
[0115] This embodiment of the present application uses a sliding rheostat as a detection unit, and can use the sliding rheostat to perform different displacement characteristics according to the tire wear condition to improve the accuracy of tire detection. In addition, the detection process is simple and the tire resistance value can be obtained without overly complicated calculations, making detection convenient.
[0116] In order to make those skilled in the art better understand this application, Figure 5 , continue to explain other solutions of this application.
[0117] See also Figure 5 , shows a detailed flow chart of the vehicle tire status reminder method in an embodiment of the present application.
[0118] In some embodiments of the present application, based on the aforementioned solution, a tire processing unit, a first detection unit, and a second detection unit are provided on the tire, and the first detection unit, the second detection unit, and the tire processing unit are connected in a straight line on the tire. The method of the present application further includes steps 510 to 540:
[0119] Step 510: During the vehicle's travel, the tire processing unit acquires the first level parameter detected by the first detection unit and the second level parameter detected by the second detection unit in real time.
[0120] This application Figure 5 In this embodiment, two detection units are installed on the tire: a first detection unit and a second detection unit. These units are aligned with the tire processing unit in a straight line. This ensures that the two detection units are spaced far apart, preventing erroneous data from both detection units due to a single tire side being in a unique environment. For example, if a road surface is uneven, one of the two detection units may be affected. By introducing two detection units, and placing them diagonally on the tire, detection accuracy can be improved.
[0121] Furthermore, in step 510 of the present application, the first level parameter detected by the first detection unit and the second level parameter detected by the second detection unit are acquired in real time by the tire processing unit, and then subsequent steps are performed.
[0122] Step 520: Obtaining the tire usage time. When the tire usage time is greater than the second preset time, determining whether the difference between the first level parameter and the second level parameter is less than or equal to a third threshold, the third threshold is greater than the first threshold, and the second preset time is less than the first preset time;
[0123] Step 520 of this application combines the tire's age and tire wear. In reality, tires of varying ages often use the same wear parameters. This can lead to invalid test results later on, as tire wear accumulates over time. Failure to adjust the wear parameters will result in poor data accuracy.
[0124] This application takes this into consideration and designs the method of step 520. In step 520 of this application, the tire usage time is obtained. When the tire usage time is greater than the second preset time, it is determined whether the difference between the first level parameter and the second level parameter is less than or equal to a third threshold value, the third threshold value is greater than the first threshold value, and the second preset time value is less than the first preset time value.
[0125] The second preset duration of the present application can be half of the first preset duration, or other durations, and can be defined based on the usage of different tires. For example, for tires of better quality, the second preset duration can be set longer, while for tires of lower quality, the second preset duration can be set shorter.
[0126] The present application determines whether the difference between the first level parameter and the second level parameter is less than or equal to a third threshold value when the tire usage time is greater than the second preset time. In the present application, when the tire usage time is greater than the second preset time, the first threshold value is no longer used for judgment, and the third threshold value is used instead, wherein the third threshold value is greater than the first threshold value. This means that after a period of use, due to the different usage frequencies of various parts of the tire, the wear conditions of each position itself are different. Therefore, if the first threshold value is still used for adjustment at this time, the second reminder signal may be frequently issued, and correct detection cannot be performed. Therefore, the present application changes the first threshold value to a larger third threshold value when the tire usage time is greater than the second preset time, and determines whether the difference between the first level parameter and the second level parameter is less than or equal to the third threshold value. This can avoid the frequent issuance of the second reminder signal due to long-term wear of the tire, thereby improving the efficiency of tire wear detection.
[0127] Step 530: If yes, determine that the current detection result is valid.
[0128] If the difference between the first level parameter and the second level parameter is less than or equal to the third threshold, it indicates that the current detection result is valid, and the process proceeds to step 540 .
[0129] Step 540: When the minimum value of the first level parameter and the second level parameter is greater than or equal to the second threshold, a first reminder signal is issued, where the first reminder signal is used to prompt the user to change tires.
[0130] Step 540 is the same as step 130 , that is, when it is determined that the minimum value of the first level parameter and the second level parameter is greater than or equal to the second threshold, a first reminder signal is issued, which will not be repeated here.
[0131] In order to make those skilled in the art better understand this application, Figure 6 , continue to explain other solutions of this application.
[0132] See also Figure 6 , shows a detailed flow chart of the vehicle tire status reminder method in an embodiment of the present application.
[0133] In some embodiments of the present application, based on the aforementioned scheme, a tire processing unit, a first detection unit, and a second detection unit are provided on the tire, and the first detection unit, the second detection unit, and the tire processing unit are connected in a straight line on the tire. The method of the present application also includes steps 610-640.
[0134] Step 610: During the driving of the vehicle, the first level parameter detected by the first detection unit and the second level parameter detected by the second detection unit are acquired in real time by the tire processing unit.
[0135] Step 620: Obtain the tire usage time. When the tire usage time is greater than the second preset time, determine whether the difference between the first level parameter and the second level parameter is less than or equal to the first threshold, and the second preset time is less than the first preset time.
[0136] The second preset duration of the present application can be half of the first preset duration, or other durations, and can be defined based on the usage of different tires. For example, for tires of better quality, the second preset duration can be set longer, while for tires of lower quality, the second preset duration can be set shorter.
[0137] Step 630: If yes, determine that the current detection result is valid.
[0138] Step 640: When the minimum value of the first level parameter and the second level parameter is greater than or equal to the fourth threshold, a first reminder signal is issued, the first reminder signal is used to prompt the user to change the tire, and the fourth threshold is less than the second threshold.
[0139] Steps 610-640 of the present application also combine the two factors of tire usage time and tire wear. However, steps 610-640 are aimed at changing the second threshold in step 130. In actual use, as the tire usage time continues, the degree of wear of various parts of the tire varies greatly. Therefore, if the second threshold is still used as the basis for judging the wear condition, it may result in some areas of the tire having reached the wear level, but this area is not detected by the detection unit (the number of detection units is limited and does not cover all areas of the tire), which will affect the detection results. Therefore, based on this point, the present application designs steps 610-640.
[0140] When the tire usage time exceeds a second preset time, the present application determines whether the difference between the first level parameter and the second level parameter is less than or equal to a first threshold, and the second preset time is less than the first preset time. If so, the current detection result is determined to be valid. When the minimum value of the first level parameter and the second level parameter is greater than or equal to a fourth threshold, a first reminder signal is issued, the first reminder signal being used to prompt the user to replace the tire, and the fourth threshold is less than the second threshold.
[0141] The present application adjusts the second threshold to a fourth threshold, which is smaller than the second threshold. Therefore, it can avoid the problem of inaccurate detection results due to different degrees of wear of the tire as it is used. By lowering the threshold, the safety factor is increased to avoid the situation where some areas are not detected by the detection unit and are severely worn and cannot be reminded.
[0142] Among them, this application Figure 5 and Figure 6 The embodiments can be combined, that is, when the tire usage time is greater than the second preset time, the first threshold can be adjusted to the third threshold and the second threshold can be adjusted to the fourth threshold at the same time.
[0143] Among them, this application Figure 5 and Figure 6 The second preset duration in can be adjusted according to actual conditions. The two can be different or the same, and this application does not impose any restrictions on this.
[0144] The above describes the embodiments of the present application. The following describes the application embodiments of the present application in detail.
[0145] In order to make those skilled in the art better understand this application, Figure 7 , continue to explain other solutions of this application.
[0146] See also Figure 7 , shows a schematic diagram of a vehicle tire status detection system in an embodiment of the present application.
[0147] In order to detect the wear of tires, this application designs a vehicle tire status detection system. Specifically, the system is composed of the following Figure 7 As shown, a central control system is installed in the middle of each wheel (corresponding to Figure 7 The central control unit is mainly used to send the resistance value change of the outer wheel edge detection to the vehicle end through radio frequency signals, and can also provide power to the entire system (with a replaceable power supply) and receive the resistance value of the outer wheel edge through the line. Among them, this central control unit is the same as the tire processing unit in the above steps.
[0148] At least 2 outer wheel edge detection devices connected to the central control system ( Figure 7 The sensing device in the previous step is the same as the detection unit. The reason for at least two is that if a stone gets stuck on an uneven road during vehicle movement, the detected resistance value will be distorted, leading to the perception of tire wear when the actual cause is a stone stuck and uneven road. The at least two values are valid only if the resistance values of the two sensors are the same during normal movement, when the tire wears. At this point, the data is transmitted to the vehicle. If the two values are inconsistent, a stone stuck fault is reported, requiring repair.
[0149] The outer wheel edge detection device could consist of a sliding rheostat. The movable end of the slider moves as the tire skin thins, while the fixed end remains unchanged. As the sliding end moves due to tire thinning, the resistance in contact with the fixed end changes, causing a change in resistance that is transmitted to the central control system. The change in resistance is linearly related to the sliding distance, making it more intuitive.
[0150] This application takes into account that the tread wear of tires during normal use requires a meter to remind you to replace them. This reminder can be displayed separately for four different tire wear levels to show the wear of each wheel. Each wheel has this system, which can achieve different displays, which is simple and intuitive.
[0151] In summary, based on the technical solution proposed in this application, this application provides a tire processing unit and at least two detection units on the tire, and determines that the current detection result is valid when the maximum difference between the at least two level parameters is less than or equal to a first threshold value. After the result is valid, a first reminder signal is issued when the maximum value of the at least two level parameters is greater than or equal to a second threshold value. The first reminder signal is used to prompt the user to replace the tire. Since this application uses at least two detection units to detect the level parameters of the tire, and determines whether the maximum difference between the at least two level parameters is less than or equal to the first threshold value, if the maximum difference between the two level parameters is less than or equal to the first threshold value, it indicates that the current detection result of the tire is valid. The method of this application can more accurately detect the level parameters of the tire, avoiding the problem of inaccurate detection results caused by the surrounding environment of the tire, such as the tire being stuck in stones or sand. Therefore, the solution of this application improves the accuracy of tire wear detection. At the same time, since it can automatically detect and issue the first reminder signal, this application also improves the convenience of user use and reduces safety hazards to a certain extent.
