Description

Technical Field

[0001] The present application relates to the technical field of connected vehicles, and in particular to a vehicle tire monitoring method and related devices. Background Art

[0002] Tires are important and vulnerable parts of vehicles, which greatly affect the safety of vehicles. Therefore, the industry has corresponding standards for tire wear and replacement. When the tire tread wear reaches a certain depth, the tire needs to be replaced in time to ensure the driving safety of the vehicle.

[0003] At present, for monitoring the degree of tire wear, measuring tools are usually used to directly measure the tire pattern to determine the degree of tire wear, but this monitoring method cannot monitor the health status of vehicle tires at any time. Alternatively, instead of using measuring tools, special sensors are used to measure the corresponding torque, slip rate and other parameters to indirectly calculate the degree of tire wear, but this monitoring method requires the installation of special sensors, resulting in increased vehicle costs. Summary of the invention

[0004] The embodiments of the present application provide a vehicle tire monitoring method and related devices, which can monitor the health status of vehicle tires at any time without installing special sensors, thereby reducing vehicle costs.

[0005] In a first aspect, an embodiment of the present application provides a vehicle tire monitoring method, which is applied to a vehicle and can be performed by a communication device. The communication device can be a device, or a chip (system) or circuit for a device, which is not limited in the present application. The method includes:

[0006] Acquire first information, the first information comprising at least one data set, a first data set in the at least one data set comprising a first vehicle speed corresponding to the vehicle and a first wheel speed corresponding to a first tire of the vehicle;

[0007] The wear degree of the first tire is determined according to the first information.

[0008] In an embodiment of the present application, a vehicle tire monitoring method is provided, which is applied to a vehicle, and a communication device obtains first information and determines the wear degree of a first tire of the vehicle according to the first information. The communication device here can also be a processor / chip that can be used to execute computer execution instructions, and the embodiment of the present application does not limit this.

[0009] The first information in the embodiment of the present application includes at least one data set, and the first data set in the at least one data set includes the first vehicle speed corresponding to the vehicle and the first wheel speed corresponding to the first tire of the vehicle. It can be understood that a data set here can be considered as a data frame, or it can exist in other data storage forms, and the embodiment of the present application does not limit this. At a certain moment when the vehicle is traveling, the vehicle has a corresponding speed, and each tire of the vehicle also has a corresponding wheel speed. The data of the vehicle speed and wheel speed together constitute the data set corresponding to the moment. It can be understood that the first information can include a data set corresponding to a certain moment, and can also include multiple data sets corresponding to a certain time period, and the embodiment of the present application does not limit this.

[0010] Through the embodiment of the present application, the wear degree of the vehicle tire can be determined only by using the vehicle speed and wheel speed data. Compared with the method of using a measuring tool to directly measure the tire pattern to determine the wear degree of the vehicle tire, the embodiment of the present application can use the vehicle speed and wheel speed data to determine the wear degree of the vehicle tire at any time, and monitor the health status of the vehicle tire at any time; compared with the method of indirectly calculating the degree of tire wear by measuring the corresponding torque, slip rate and other parameters through special sensors, the embodiment of the present application can determine the degree of wear of the vehicle tire only based on the sensors for measuring the vehicle speed and wheel speed that are conventionally configured on the vehicle without installing special sensors, thereby reducing vehicle costs.

[0011] In a possible implementation manner, determining the wear degree of the first tire according to the first information includes:

[0012] converting the first wheel speed into a first rotational speed and converting the first vehicle speed into a first reference rotational speed according to the specification information of the first tire;

[0013] The wear degree of the first tire is determined according to the first rotation speed and the first reference rotation speed.

[0014] In an embodiment of the present application, a possible specific implementation method for determining the wear degree of a first tire is provided, specifically, first, according to the specification information of the first tire, the speed data in the above-mentioned first data set is converted into rotation speed data, for example, the first wheel speed is converted into a first rotation speed, and the first vehicle speed is converted into a first reference rotation speed, and then the wear degree of the first tire is determined according to the first rotation speed and the first reference rotation speed. It can be understood that the speed data here includes but is not limited to data in kilometers per hour (km / h), and the rotation speed data here includes but is not limited to data in revolutions per minute (rpm). The first rotation speed can be considered as the rotation speed corresponding to the first tire, and the first reference rotation speed can be considered as the rotation speed corresponding to the standard specification tire used as a reference. It can be understood that the specification information of the first tire includes but is not limited to various size information related to the first tire, and the embodiment of the present application does not limit this. Since the vehicle speed and the wheel speed of the tire are very close during driving, it is difficult to accurately determine the tire wear condition based on the difference between the vehicle speed and the wheel speed. The embodiment of the present application amplifies the difference between the vehicle speed and the wheel speed by converting the speed data into rotational speed data, and then determines the tire wear condition based on the difference in the amplified rotational speed data, thereby obtaining a more accurate tire wear degree.

[0015] In a possible implementation manner, determining the wear degree of the first tire according to the first rotational speed and the first reference rotational speed includes:

[0016] An error of the first rotation speed relative to the first reference rotation speed is determined as the wear degree of the first tire.

[0017] In the embodiment of the present application, a possible specific implementation method for determining the wear degree of the first tire is provided, specifically, the error of the first rotational speed relative to the first reference rotational speed is determined as the wear degree of the first tire, the first rotational speed can be considered as the rotational speed corresponding to the first tire, and the first reference rotational speed can be considered as the rotational speed corresponding to the standard specification tire used as a reference. Since the vehicle speed and the wheel speed of the tire are very close during the driving process of the vehicle, it is difficult to accurately determine the wear condition of the tire based on the difference between the vehicle speed and the wheel speed. The embodiment of the present application amplifies the difference between the vehicle speed and the wheel speed by converting the speed data into the rotational speed data, and then determines the wear condition of the tire based on the difference in the amplified rotational speed data (i.e., the error of the first rotational speed relative to the first reference rotational speed), so that a more accurate tire wear degree can be obtained.

[0018] In a possible implementation, the number of the first data sets is N, the wear degree of the first tire is associated with a first rotational speed and a first reference rotational speed corresponding to each of the N first data sets, and N is an integer greater than 1.

[0019] In the embodiment of the present application, a possible specific implementation method for determining the wear degree of the first tire is provided, specifically, the first information includes N first data sets corresponding to a certain time period, each of the N first data sets includes the vehicle speed and the wheel speed of each tire corresponding to a certain moment in a certain time period, and according to the tire specification information, the speed data is converted into rotation speed data, and the first rotation speed and the first reference rotation speed corresponding to each first data set can be obtained. At this time, the wear degree of the first tire is associated with the first rotation speed and the first reference rotation speed corresponding to each first data set in the N first data sets. It can be understood that, in the case where the first information includes N first data sets, the error of the first rotation speed corresponding to each first data set relative to the first reference rotation speed is calculated, and then the average relative error corresponding to the N first data sets can be obtained by taking the average or weighted average of the errors corresponding to the N first data sets, and the average relative error is determined as the wear degree of the first tire. Through the embodiment of the present application, the speed data is converted into rotation speed data to amplify the difference between the vehicle speed and the wheel speed, and the wear condition of the tire is determined according to the average relative error corresponding to multiple first data sets in a certain period of time, so that a more accurate tire wear degree can be obtained.

[0020] In a possible implementation manner, the wear degree of the first tire is further associated with a first weight corresponding to each first data set in the N first data sets, and the first weight is associated with a tire pressure corresponding to each first data set in the N first data sets.

[0021] In an embodiment of the present application, a possible specific implementation method for determining the wear degree of a first tire is provided, specifically, when the first information includes N first data sets, the error of the first rotation speed corresponding to each first data set relative to the first reference rotation speed is calculated, and then the average relative error corresponding to the N first data sets is obtained by taking the average or weighted average of the errors corresponding to the N first data sets, and the average relative error is determined as the wear degree of the first tire. The wear degree of the first tire (i.e., the average relative error) is also associated with the first weight corresponding to each first data set in the N first data sets, and the first weight is associated with the tire pressure corresponding to each first data set in the N first data sets. It can be understood that when the errors corresponding to the N first data sets are weighted averaged, the weights of the errors corresponding to each first data set may be the same or different, and the weights may also be determined by the tire pressure of the vehicle tire at the time corresponding to the first data set. For example, when performing weighted averaging on the errors corresponding to N first data sets, when the tire pressure of the vehicle tire at the time corresponding to a certain first data set is an intermediate value within the normal tire pressure range, the weight of the error corresponding to the first data set is the largest, and when the tire pressure of the vehicle tire at the time corresponding to a certain first data set is the minimum value or the maximum value within the normal tire pressure range, the weight of the error corresponding to the first data set is the smallest, that is, the weight of the error corresponding to the first data set and the tire pressure of the vehicle tire at the time corresponding to the first data set satisfy a relationship similar to a normal distribution. Through the embodiments of the present application, when performing weighted averaging on the errors corresponding to N first data sets, the weight of the error corresponding to each first data set is associated with the tire pressure of the vehicle tire at the time corresponding to the first data set, so that the average relative error corresponding to the N first data sets obtained can be more in line with the actual use scenario of the tire, thereby obtaining a more accurate tire wear degree.

[0022] In a possible implementation manner, the first data set satisfies at least one of the following conditions:

[0023] The first vehicle speed is greater than a first threshold, the wheel speed of the tires of the vehicle is in a first interval, and the tires of the vehicle include the first tire.

[0024] In an embodiment of the present application, a possible specific implementation of a first data set is provided, specifically, the vehicle speed in the first data set is greater than a first threshold value, and / or the wheel speed of the vehicle tire in the first data set is in a first interval. Specifically, the first data set includes a first vehicle speed corresponding to the vehicle and a first wheel speed corresponding to the first tire of the vehicle, the first vehicle speed is greater than the first threshold value, and / or the first wheel speed is in a first interval. It can be understood that the first threshold value and the first interval are not fixed values, and can be adjusted according to different tire usage scenarios. For example, the first threshold value can be configured as 40km / h, and the endpoint value of the first interval can be configured according to the wheel speed of all tires of the vehicle, which is not limited in the embodiment of the present application. Through the embodiment of the present application, filtering conditions are set for the vehicle speed data and the wheel speed data, and invalid sampling data, such as extreme values, null values, etc., can be removed to obtain a valid first data set, thereby calculating a more accurate tire wear degree.

[0025] In a possible implementation manner, the first data set also includes a tire pressure of the vehicle corresponding to a first moment, and the tire pressure of the vehicle corresponding to the first moment is in a second range, and the first moment is the moment corresponding to the first data set.

[0026] In an embodiment of the present application, a possible specific implementation of a first data set is provided, specifically, the tire pressure of the vehicle tire at the time corresponding to the first data set is in a second interval. It can be understood that the second interval is not a fixed value and can be adjusted according to different tire usage scenarios. For example, the second interval can be configured to be 2.0 to 3.5 bar, and the embodiment of the present application does not limit this. Through the embodiment of the present application, a screening condition is set for the tire pressure of the vehicle tire at the time corresponding to the first data set, and invalid sampling data such as extreme values ​​and null values ​​can be removed to obtain a valid first data set, thereby calculating a more accurate tire wear degree, and making the calculated tire wear degree more in line with the actual use scenario of the tire.

[0027] In a possible implementation manner, the endpoint value of the first interval is preconfigured;

[0028] Alternatively, the endpoint values ​​of the first interval are associated with the average value of the wheel speed corresponding to at least one tire of the vehicle at a first moment and the standard deviation of the wheel speed corresponding to at least one tire of the vehicle at the first moment, and the first moment is the moment corresponding to the first data set.

[0029] In an embodiment of the present application, a possible specific implementation of the endpoint value of the first interval is provided, specifically, the endpoint value of the first interval can be pre-configured, specifically can be system configured, and can also be user configured, and the endpoint value of the configured first interval is not a fixed value, and can be adjusted according to different tire usage scenarios. Alternatively, the endpoint value of the first interval can also be configured according to the wheel speed of at least one tire of the vehicle, specifically can be configured according to the average value of the wheel speed corresponding to at least one tire of the vehicle and the standard deviation of the wheel speed corresponding to at least one tire of the vehicle. Through the embodiment of the present application, a screening condition is set for the tire pressure of the vehicle tire at the corresponding moment of the first data set, and invalid sampling data, such as extreme values, null values, etc., can be removed to obtain a valid first data set, thereby calculating a more accurate tire wear degree, and making the calculated tire wear degree more in line with the actual tire usage scenario.

[0030] Optionally, a coefficient may be configured for each tire. When calculating the wear of a certain tire, a first interval screening condition is set for the tire pressure of the vehicle tire at the time corresponding to the first data set. The endpoint value of the first interval may be determined by the coefficient configured for the tire, the average value of the wheel speed corresponding to at least one tire of the vehicle, and the standard deviation of the wheel speed corresponding to at least one tire of the vehicle. Since the coefficient configured for the tire is associated with factors such as the hardware performance of the tire, the user's driving habits, and the driving road conditions, the first interval determined according to the coefficient can more effectively remove invalid sampling data, such as extreme values, null values, etc., to obtain a valid first data set, thereby calculating a more accurate tire wear degree, and making the calculated tire wear degree more in line with the actual use scenario of the tire.

[0031] In a possible implementation manner, the specification information of the first tire includes at least one of the following:

[0032] The outer diameter of the first tire, a parameter set of the width, aspect ratio, and hub diameter of the first tire.

[0033] In an embodiment of the present application, a possible specific implementation of the specification information of a first tire is provided, specifically, the specification information of the first tire includes but is not limited to various dimensional information related to the first tire, which is used to convert speed data into rotational speed data. The specification information of the first tire may directly include the outer diameter of the first tire, which is used to convert speed data into rotational speed data. Alternatively, the specification information of the first tire may also include a parameter set of the width, flatness, and hub diameter of the first tire, which is used to indirectly calculate the outer diameter of the first tire, thereby converting speed data into rotational speed data. It can be understood that the specification information of the first tire includes various dimensional information that can be used to obtain the outer diameter of the first tire. As for the content of the specific included dimensional information, the embodiment of the present application does not limit this.

[0075] It is understandable that, in one possible case, after the remote server determines the wear degree of the first tire and / or the life information of the first tire, it controls the wear degree of the first tire and / or the life information of the first tire to be displayed on a device with a display function such as a vehicle-side computer / mobile phone APP / smart wearable device, in which case the remote server is independently deployed outside the vehicle, and has a wireless communication connection with the vehicle-side computer / mobile phone APP / smart wearable device, etc. In another possible case, the remote server is integrated into the vehicle, and after the vehicle-side computer determines the wear degree of the first tire and / or the life information of the first tire, it displays the wear degree of the first tire and / or the life information of the first tire.

[0076] Through the embodiments of the present application, the wear degree of the first tire of the vehicle and / or the life information of the first tire are displayed, which can effectively provide the user with the current tire health status and health status development trend, so that the user can monitor the health status of the vehicle tires at any time, so as to replace or repair the tires in time and ensure the safety of vehicle driving.

For example, the user may be prompted through a screen, sound, light, electricity, vibration, etc.

[0079] In the implementation mode of the present application, the life information includes at least one of the following: the remaining mileage that can be used, the remaining service life, and the time to reach the replacement condition. It can be understood that the remaining service life of the first tire refers to the remaining time before the first tire is scrapped predicted by theoretical calculation, and the time to reach the replacement condition of the first tire refers to the remaining available time that the first tire may affect the driving safety of the vehicle and thus needs to be replaced in combination with the actual driving scenario. Among them, the actual driving scenario may include but is not limited to the purpose of the vehicle (commercial vehicle, family car), the load of the vehicle (truck, bus), the size of the vehicle (large car, medium-sized car, small car), the hardware performance of the vehicle tire, the user's driving habits, driving road conditions, etc.

It is understandable that a data set here can be considered as a data frame, or it can exist in other data storage forms, and the embodiment of the present application does not limit this. At a certain moment when the vehicle is traveling, the vehicle corresponds to a vehicle speed, and each tire of the vehicle also corresponds to a wheel speed. The data of the vehicle speed and wheel speed together constitute the data set corresponding to the moment. It is understandable that the first information can include a data set corresponding to a certain moment, and can also include multiple data sets corresponding to a certain time period, and the embodiment of the present application does not limit this.

[0142] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0143] The terms "first" and "second" in the specification, claims and drawings of this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0144] The "embodiment" mentioned in this article means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be explicitly and implicitly understood by those skilled in the art that in the various embodiments of the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0145] It should be understood that in the present application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0146] It should be noted that in this application, "indication" may include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0147] In the present application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association relationship between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by the protocol), thereby reducing the indication overhead to a certain extent. The information to be indicated can be sent together as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or can be configured by the transmitting end device by sending configuration information to the receiving end device.

[0148] It should be noted that in this application, "send" can be understood as "output", and "receive" can be understood as "input". "Send information to A", where "to A" only indicates the direction of information transmission, A is the destination, and does not limit "sending information to A" to direct transmission on the air interface. "Sending information to A" includes sending information directly to A, and also includes sending information to A indirectly through a transmitter, so "sending information to A" can also be understood as "outputting information to A". Similarly, "receiving information from A" indicates that the source of the information is A, including receiving information directly from A, and also includes receiving information indirectly from A through a receiver, so "receiving information from A" can also be understood as "inputting information from A".

[0149] The present application provides a vehicle tire monitoring method, which is applied to the field of connected vehicle technology, such as monitoring of vehicle tires of smart electric vehicles or smart electric bicycles, etc. In order to more clearly describe the solution of the present application, some knowledge related to tire monitoring is first introduced below.

[0150] Tires are important and vulnerable parts of vehicles, which greatly affect the safety of vehicles. Therefore, the industry has corresponding standards for tire wear and replacement. When the tire tread wear reaches a certain depth, the tire needs to be replaced in time to ensure the driving safety of the vehicle.

[0151] Electric vehicles have greater torque and react faster when starting than fuel vehicles, so they are subject to greater ground reaction force when starting. Therefore, electric vehicle tires need to be able to withstand greater weight and achieve a more durable effect. Since electric vehicle tires have to withstand greater loads than fuel vehicle tires and electric vehicles react faster when starting, electric vehicle tires wear faster than fuel vehicle tires. In addition, for commercial vehicles, tires are in working condition for a long time, wear faster, and face greater safety risks. Therefore, more monitoring and more detailed information are needed to ensure the safety of tires.

[0152] At present, for monitoring the degree of tire wear, measuring tools are usually used to directly measure the tire pattern to determine the degree of tire wear, but this monitoring method cannot monitor the health status of vehicle tires at any time. Alternatively, instead of using measuring tools, special sensors are used to measure the corresponding torque, slip rate and other parameters to indirectly calculate the degree of tire wear, but this monitoring method requires the installation of special sensors, resulting in increased vehicle costs.

[0153] In view of this, an embodiment of the present application provides an architecture of a vehicle tire monitoring system, and based on the architecture, proposes a new vehicle tire monitoring method, which can determine the wear of the vehicle tires using only the vehicle speed and wheel speed data. It can monitor the health status of the vehicle tires at any time and does not require the installation of special sensors, thereby reducing vehicle costs.

[0154] See also Figure 1A and Figure 1B , Figure 1A and Figure 1B A schematic diagram of the architecture of a vehicle tire monitoring system provided in an embodiment of the present application.

[0155] like Figure 1A As shown, the architecture of the vehicle tire monitoring system is mainly used for monitoring information such as vehicle tire wear and vehicle tire life, involving two major parts: the vehicle side and the remote server side.

[0156] The vehicle side and the remote server side are connected via a wireless network.

[0157] The vehicle side includes but is not limited to a data acquisition system for collecting the current state of the vehicle, including but not limited to the vehicle speed, the wheel speed of each tire, the tire pressure of each tire, etc. It is understandable that the data acquisition system includes but is not limited to sensors for measuring vehicle speed, wheel speed, and tire pressure that are conventionally configured on the vehicle, and is used to collect various types of vehicle data. The vehicle side sends the collected data to the remote server side.

[0158] The remote server includes but is not limited to data storage system, data processing system, data analysis system, data evaluation system, etc. Its functions are described as follows:

[0159] After receiving the data from the vehicle, the remote server stores the data in the data storage system.

[0160] After the data processing system extracts the required data from the data storage system, it cleans the data, removes invalid sampled data, such as extreme values, null values, etc., filters out valid data, and performs data segmentation on the valid data. For example, the data can be segmented by time, and the valid data can be segmented into driving data segments for each day or each time period. For another example, the data can be segmented by mileage, and the valid data can be segmented into driving data segments for each mileage, and so on. The embodiments of the present application do not limit this.

[0161] The data analysis system analyzes the segmented valid data, calculates the tire wear, predicts the tire life information, stores the tire wear and tire life information in the data storage system, and sends the tire wear and tire life information to the data evaluation system.

[0162] After receiving the tire wear and tire life information from the data analysis system, the data evaluation system evaluates the health status of the tire based on the tire wear and tire life information, and outputs the tire evaluation information. It can provide users with tire quality and cost evaluation analysis to reduce the maintenance cost of vehicle tires and ensure vehicle driving safety.

[0163] Optionally, the data evaluation system will also send tire wear and tire life information to the vehicle / mobile phone APP / smart wearable device and other devices with display functions for display, and issue early warnings to users through screen, sound, light, electricity, vibration, etc.

[0164] Based on the above vehicle tire monitoring system architecture description, the workflow of the entire vehicle tire monitoring system can be as follows:

[0165] (1) The server classifies the vehicles and configures tire parameters. The vehicle classification may include but is not limited to the purpose of the vehicle (commercial vehicle, family car), the load of the vehicle (truck, bus), the size of the vehicle (large vehicle, medium vehicle, small vehicle), etc. Optionally, the tire parameters are configured to support individual configuration by users, such as configuring tire specifications through a mobile phone APP, or the system administrator can also be configured in the background, which is not limited in the present embodiment of the application.

[0166] (2) Clean the data reported by each vehicle to remove invalid sampling data, such as extreme values ​​and null values, and filter out valid data.

[0167] (3) The filtered valid data is divided into driving data segments for each day or each time period according to time, or divided into driving data segments for each mileage according to mileage.

[0168] (4) Extract relevant features from the driving data segment, calculate the wear of each tire, and store the records.

[0169] (5) For each vehicle, predict the tire life based on the wear data recorded every day, every time period, or every mileage period.

[0170] (6) Produce an analysis report on the current tires of all current vehicles, including but not limited to the health status of the tires, the wear of the tires, the quality assessment of the tires, the cost assessment of the use of the tires, etc., which is not limited to this embodiment of the present application.

[0171] (7) For a single vehicle, the remote server sends the tire wear and tire life prediction results to the vehicle / mobile phone APP / smart wearable device and other devices with display functions, and issues an early warning.

[0172] like Figure 1B As shown, the architecture of the vehicle tire monitoring system is mainly used to monitor information such as vehicle tire wear and vehicle tire life, involving the vehicle side.

[0173] The vehicle side includes but is not limited to data acquisition system, data storage system, data processing system, data analysis system, data evaluation system, etc. Its functional description can be referred to Figure 1A The corresponding description is not repeated here.

[0174] It is understandable that in the above Figure 1A In the vehicle tire monitoring system shown, the remote server is independently deployed outside the vehicle, and has a wireless communication connection with the vehicle-side computer / mobile phone APP / smart wearable device and other devices with display functions. After the remote server determines the tire wear and / or tire life information, it controls the tire wear and / or tire life information to be displayed on the vehicle-side computer / mobile phone APP / smart wearable device and other devices with display functions. Figure 1B In the vehicle tire monitoring system shown, the remote server is integrated with the vehicle, and after the vehicle computer determines the tire wear and / or the tire life information, it displays the tire wear and / or the tire life information.

[0175] Based on the above Figure 1A and Figure 1B The vehicle tire monitoring system architecture shown in FIG. 1 is a vehicle tire monitoring system architecture shown in FIG. 1 . The present application embodiment also provides a new vehicle tire monitoring method. Figures 2 to 6 The vehicle tire monitoring method is described.

[0176] See also Figure 2 , Figure 2A flow chart of a vehicle tire monitoring method provided in an embodiment of the present application. The vehicle tire monitoring method is applied to the field of connected vehicle technology, such as monitoring of vehicle tires of smart electric vehicles or smart electric bicycles. Specifically, the vehicle tire monitoring method includes but is not limited to the following steps:

[0177] S201: Acquire first information.

[0178] S202: Determine the wear degree of the first tire according to the first information.

[0179] Optionally, the device for obtaining the first information and determining the wear degree of the first tire according to the first information in the embodiment of the present application may be a first communication device, which is a device equipped with a processor / chip that can be used to execute computer-executable instructions, or a processor / chip that can be used to execute computer-executable instructions, and the embodiment of the present application does not limit this. Optionally, the first communication device may be a vehicle end, or a processor / chip in the vehicle end, for example, specifically, the above-mentioned Figure 1B The vehicle end in the vehicle tire monitoring system shown is used to execute the vehicle tire monitoring method in the embodiment of the present application, so as to determine the wear of the vehicle tires using only the vehicle speed and wheel speed data. This can monitor the health status of the vehicle tires at any time and does not require the installation of special sensors, thereby reducing vehicle costs.

[0180] Optionally, the device used to obtain the first information and determine the wear degree of the first tire according to the first information in the embodiment of the present application may also be a second communication device, and the second communication device is a device equipped with a processor / chip that can be used to execute computer-executable instructions, or a processor / chip that can be used to execute computer-executable instructions, and the embodiment of the present application does not limit this. Optionally, the second communication device may be a remote server, or a processor / chip in the remote server, for example, the second communication device may be the above-mentioned Figure 1A The remote server end in the vehicle tire monitoring system shown is used to execute the vehicle tire monitoring method in the embodiment of the present application, so as to determine the wear degree of the vehicle tire only by using the vehicle speed and wheel speed data, which can monitor the health status of the vehicle tire at any time and reduce the vehicle cost without installing special sensors. At this time, the second communication device (remote server end) and the first communication device (vehicle end) constitute a vehicle tire monitoring system, and its architecture can be specifically referred to the above Figure 1A The description is not repeated here.

[0181] It is understandable that the vehicle in the embodiment of the present application can be replaced by a terminal device, which can be a mobile robot or other terminal device that is driven by a power battery and needs to move with the help of tires. The embodiment of the present application does not make specific limitations on this.

[0182] The first information includes at least one data set, and a first data set in the at least one data set includes a first vehicle speed corresponding to the vehicle and a first wheel speed corresponding to a first tire of the vehicle.

[0183] It is understandable that a data set here can be considered as a data frame, or can exist in other data storage forms, and the embodiments of the present application do not limit this. At a certain moment of vehicle driving, the vehicle corresponds to a vehicle speed, and each tire of the vehicle also corresponds to a wheel speed. The data of the vehicle speed and wheel speed together constitute the data set corresponding to the moment.

[0184] For example, taking a vehicle with four tires (left front wheel, right front wheel, left rear wheel, right rear wheel) as an example, the data set corresponding to a certain time t can be expressed as follows:

[0185]

[0186] Among them, the units of wheel speed and vehicle speed in the above table are speed units, such as km / h.

[0187] It is understandable that the first information may include a data set corresponding to a certain moment, or may include multiple data sets corresponding to a certain time period, and the embodiment of the present application is not limited to this.

[0188] In the embodiment of the present application, the wear degree of the vehicle tire can be determined only by using the vehicle speed and wheel speed data. Compared with the method of using a measuring tool to directly measure the tire pattern to determine the wear degree of the vehicle tire, the embodiment of the present application can use the vehicle speed and wheel speed data to determine the wear degree of the vehicle tire at any time, and monitor the health status of the vehicle tire at any time; compared with the method of indirectly calculating the degree of tire wear by measuring the corresponding torque, slip rate and other parameters through special sensors, the embodiment of the present application can determine the degree of wear of the vehicle tire only based on the sensors for measuring the vehicle speed and wheel speed that are conventionally configured on the vehicle without installing special sensors, thereby reducing vehicle costs.

[0189] In a possible embodiment, the above step S202 may be specifically implemented as follows:

[0190] According to the specification information of the first tire, the first wheel speed is converted into a first rotation speed, and the first vehicle speed is converted into a first reference rotation speed; according to the first rotation speed and the first reference rotation speed, the wear degree of the first tire is determined.

[0191] It can be understood that the speed data in the above-mentioned first data set is first converted into rotational speed data based on the specification information of the first tire. For example, the first wheel speed is converted into the first rotational speed, and the first vehicle speed is converted into the first reference rotational speed. Then, the wear degree of the first tire is determined based on the first rotational speed and the first reference rotational speed.

[0192] It is understood that the speed data herein include but are not limited to data in kilometers per hour (km / h), and the speed data herein include but are not limited to data in revolutions per minute (rpm). The first speed may be considered as a speed corresponding to the first tire, and the first reference speed may be considered as a speed corresponding to a tire of a standard specification used as a reference.

[0193] It can be understood that the specification information of the first tire includes but is not limited to various dimensional information related to the first tire, which is used to obtain the outer diameter of the first tire and then to convert the speed data into rotational speed data. As for the specific content of the dimensional information included, the embodiment of the present application does not limit this.

[0194] Optionally, the specification information of the first tire may directly include the outer diameter of the first tire, which is used to convert the speed data into rotation speed data.

[0195] Optionally, the specification information of the first tire may also include a parameter set of the width, aspect ratio, and hub diameter of the first tire, which is used to indirectly calculate the outer diameter of the first tire, thereby converting the speed data into rotation speed data.

[0196] Exemplarily, when the specification information of the first tire includes the width, aspect ratio, and hub diameter of the tire, the speed data (first wheel speed, first vehicle speed) may be converted into rotation speed data (first rotation speed, first reference rotation speed) by the following formula according to the specification information of the first tire:

[0197]

[0198] Among them, v rpm Indicates the speed data, v kmh represents speed data, d represents the outer diameter of the tire, and the calculation formula is as follows:

[0199]

[0200] Among them, L is the width of the tire, V is the aspect ratio, and r is the wheel diameter (in inches). For example, for a tire with specifications of "L=255, V=50, r=20", its outer diameter is d=2*255*50 / 100+20*25.4=763mm.

[0201] It is understandable that since the vehicle speed and the wheel speed of the tire are very close during driving, it is difficult to accurately determine the tire wear condition based on the difference between the vehicle speed and the wheel speed. The embodiment of the present application amplifies the difference between the vehicle speed and the wheel speed by converting the speed data into rotational speed data, and then determines the tire wear condition based on the difference in the amplified rotational speed data, thereby obtaining a more accurate tire wear degree.

[0202] In a possible embodiment, the step of “determining the wear degree of the first tire according to the first rotation speed and the first reference rotation speed” in the above step may be specifically implemented as follows:

[0203] An error of the first rotation speed relative to the first reference rotation speed is determined as the degree of wear of the first tire.

[0204] The first rotation speed may be considered as a rotation speed corresponding to the first tire, the first reference rotation speed may be considered as a rotation speed corresponding to a tire of a standard specification used as a reference, and the error of the first rotation speed relative to the first reference rotation speed may be expressed by the following formula:

[0205]

[0206] The above g represents the first rotational speed, and the above h represents the first reference rotational speed. g and h can be obtained by the conversion formula between the above speed data and the rotational speed data.

[0207] Since the vehicle speed and the wheel speed of the tire are very close during driving, it is difficult to accurately determine the tire wear condition based on the difference between the vehicle speed and the wheel speed. The embodiment of the present application amplifies the difference between the vehicle speed and the wheel speed by converting the speed data into rotational speed data, and then determines the tire wear condition based on the difference in the amplified rotational speed data (i.e., the error of the first rotational speed relative to the first reference rotational speed), thereby obtaining a more accurate tire wear degree.

[0208] In a possible embodiment, when the first information includes N first data sets, the wear degree of the first tire is associated with the first rotation speed and the first reference rotation speed corresponding to each first data set in the N first data sets, where N is an integer greater than 1. In this case, the specific implementation of determining the wear degree of the first tire may be as follows:

[0209] Among them, the first information includes N first data sets corresponding to a certain time period, and each first data set in the N first data sets includes the vehicle speed and the wheel speed of each tire corresponding to a certain moment in a certain time period. According to the specification information of the tire, the speed data is converted into rotational speed data, and the first rotational speed and the first reference rotational speed corresponding to each first data set can be obtained. At this time, the wear degree of the first tire is associated with the first rotational speed and the first reference rotational speed corresponding to each first data set in the N first data sets.

[0210] It can be understood that, in the case where the first information includes N first data sets, the error of the first rotation speed corresponding to each first data set relative to the first reference rotation speed is calculated, and then the average relative error corresponding to the N first data sets is obtained by averaging the errors corresponding to the N first data sets. The average relative error is determined as the wear degree of the first tire, which can be specifically expressed by the following formula:

[0211]

[0212] The above i represents the first speed corresponding to the i-th first data set among the N first data sets. The above h i represents the first reference speed corresponding to the i-th first data set among the N first data sets, g i and h i It can be obtained by the conversion formula of the speed data and the rotation speed data, where N is the number of the first data sets. It can be seen that the formula represents taking the average value of the errors corresponding to the N first data sets to obtain the average relative error corresponding to the N first data sets.

[0213] Through the embodiments of the present application, the speed data is converted into rotational speed data to amplify the difference between the vehicle speed and the wheel speed, and the tire wear condition is determined based on the average relative error corresponding to multiple first data sets within a certain period of time, so that a more accurate tire wear degree can be obtained.

[0214] In a possible embodiment, when the first information includes N first data sets, the wear degree of the first tire is associated with the first rotation speed, the first reference rotation speed, and the first weight corresponding to each first data set in the N first data sets, where N is an integer greater than 1. In this case, the specific implementation of determining the wear degree of the first tire may be as follows:

[0215] The first information includes N first data sets corresponding to a certain time period, each of the N first data sets includes the vehicle speed and the wheel speed of each tire corresponding to a certain moment in the certain time period, and each first data set also corresponds to a first weight. According to the tire specification information, the speed data is converted into rotation speed data, and the first rotation speed and the first reference rotation speed corresponding to each first data set can be obtained. At this time, the wear degree of the first tire is associated with the first rotation speed, the first reference rotation speed and the first weight corresponding to each first data set in the N first data sets.

[0216] It can be understood that, in the case where the first information includes N first data sets, the error of the first rotation speed corresponding to each first data set relative to the first reference rotation speed is calculated, and then the weighted average of the errors corresponding to the N first data sets is taken by using the first weights corresponding to the N first data sets, so that the average relative error corresponding to the N first data sets can be obtained, and the wear degree of the first tire is determined by the average relative error, which can also be specifically expressed by the following formula:

[0217]

[0218] The above k i represents the first weight corresponding to the i-th first data set among the N first data sets, and is used to perform weighted averaging on the errors corresponding to the N first data sets. The above g i represents the first speed corresponding to the i-th first data set among the N first data sets. The above h i represents the first reference speed corresponding to the i-th first data set among the N first data sets, g i and h i It can be obtained by the conversion formula of the speed data and the rotation speed data, where N is the number of the first data sets. It can be seen that the formula represents taking the weighted average of the errors corresponding to the N first data sets to obtain the average relative error corresponding to the N first data sets.

[0219] Through the embodiments of the present application, the speed data is converted into rotational speed data to amplify the difference between the vehicle speed and the wheel speed, and the tire wear condition is determined based on the average relative error corresponding to multiple first data sets within a certain period of time, so that a more accurate tire wear degree can be obtained.

[0220] Optionally, the above k i (The first weight) is also associated with the tire pressure corresponding to the i-th first data set among the N first data sets.

[0221] It is understandable that when weighted averaging is performed on the errors corresponding to N first data sets, the weight of the error corresponding to each first data set may be the same or different, and the weight may also be determined by the tire pressure of the vehicle tire at the time corresponding to the first data set.

[0222] For example, when weighted averaging the errors corresponding to N first data sets, when the tire pressure of the vehicle tire at the time corresponding to a certain first data set is the middle value within the normal tire pressure range (configurable), the weight of the error corresponding to the first data set is the largest, and when the tire pressure of the vehicle tire at the time corresponding to a certain first data set is the minimum or maximum value within the normal tire pressure range, the weight of the error corresponding to the first data set is the smallest, that is, the weight of the error corresponding to the first data set and the tire pressure of the vehicle tire at the time corresponding to the first data set satisfy a relationship similar to a normal distribution. It can be understood that the set tire pressure range is configurable, for example, it can be configured to 2.0 to 3.5 bar, and the embodiments of the present application do not limit this.

[0223] Through the embodiments of the present application, when performing weighted averaging on the errors corresponding to N first data sets, the weight of the error corresponding to each first data set is associated with the tire pressure of the vehicle tire at the time corresponding to the first data set. This can make the obtained average relative error corresponding to the N first data sets more in line with the actual usage scenario of the tire, thereby obtaining a more accurate tire wear degree.

[0224] In a possible embodiment, the first data set satisfies at least one of the following conditions:

[0225] The first vehicle speed is greater than a first threshold, and the wheel speeds of the tires of the vehicle (including the first tire) are in a first interval.

[0226] Specifically, the first data set includes a first vehicle speed corresponding to the vehicle and a first wheel speed corresponding to a first tire of the vehicle, the first vehicle speed is greater than a first threshold, and / or the first wheel speed is in a first interval.

[0227] It can be understood that the first threshold and the first interval are not fixed values ​​and can be adjusted according to different tire usage scenarios. For example, the first threshold can be configured to 40km / h, and the endpoint value of the first interval can be configured according to the wheel speed of all tires of the vehicle. The embodiment of the present application does not limit this.

[0228] Through the embodiment of the present application, by setting filtering conditions for the vehicle speed data and the wheel speed data, invalid sampling data, such as extreme values, null values, etc., can be removed to obtain a valid first data set, thereby calculating a more accurate tire wear degree.

[0229] In a possible embodiment, the first data set further includes the tire pressure of the vehicle corresponding to the first moment, and the tire pressure of the vehicle corresponding to the first moment is in the second range, and the first moment is the moment corresponding to the first data set.

[0230] It is understandable that the second interval is not a fixed value and can be adjusted according to different tire usage scenarios. For example, the second interval can be configured as 2.0 to 3.5 bar, and the embodiment of the present application does not limit this.

[0231] Through the embodiments of the present application, by setting filtering conditions for the tire pressure of the vehicle tire at the corresponding moment of the first data set, invalid sampling data, such as extreme values, null values, etc., can be removed to obtain a valid first data set, thereby calculating a more accurate tire wear degree and making the calculated tire wear degree more in line with the actual use scenario of the tire.

[0232] Optionally, the endpoint values ​​of the first interval are preconfigured; or, the endpoint values ​​of the first interval are associated with the average value of the wheel speed corresponding to at least one tire of the vehicle at a first moment and the standard deviation of the wheel speed corresponding to at least one tire of the vehicle at the first moment, the first moment being the moment corresponding to the first data set.

[0233] Specifically, the endpoint value of the first interval may be pre-configured, specifically system-configured, or user-configured, and the configured endpoint value of the first interval is not a fixed value and may be adjusted according to different tire usage scenarios. Alternatively, the endpoint value of the first interval may also be configured according to the wheel speed of at least one tire of the vehicle, specifically according to the average value of the wheel speed corresponding to at least one tire of the vehicle and the standard deviation of the wheel speed corresponding to at least one tire of the vehicle.

[0234] Exemplarily, the first interval may be configured as [PQ, P+Q], wherein P is an average value of the wheel speeds corresponding to all tires of the vehicle, and Q is a standard deviation of the wheel speeds corresponding to all tires of the vehicle.

[0235] Through the embodiments of the present application, by setting filtering conditions for the tire pressure of the vehicle tire at the corresponding moment of the first data set, invalid sampling data, such as extreme values, null values, etc., can be removed to obtain a valid first data set, thereby calculating a more accurate tire wear degree and making the calculated tire wear degree more in line with the actual use scenario of the tire.

[0236] Optionally, a coefficient may be configured for each tire. When calculating the wear degree of a certain tire, a first interval screening condition may be set for the tire pressure of the vehicle tire at the corresponding moment of the first data set. The endpoint value of the first interval may be determined by the coefficient of the tire configuration, the average value of the wheel speed corresponding to at least one tire of the vehicle, and the standard deviation of the wheel speed corresponding to at least one tire of the vehicle.

[0237] Exemplarily, the first interval can be configured as [Pj*Q, P+j*Q], where P is the average wheel speed corresponding to all tires of the vehicle, Q is the standard deviation of the wheel speed corresponding to all tires of the vehicle, and j is the coefficient of the tire configuration.

[0238] Since the coefficient configured for the tire is related to factors such as the hardware performance of the tire, the user's driving habits, and driving road conditions, the first interval determined according to the coefficient can more effectively remove invalid sampling data, such as extreme values, null values, etc., to obtain a valid first data set, thereby calculating a more accurate tire wear degree and making the calculated tire wear degree more in line with the actual usage scenario of the tire.

[0239] In a possible embodiment, the vehicle tire monitoring method may also include but is not limited to the following steps:

[0240] Life information of the first tire is determined based on the degree of wear of the first tire.

[0241] The life information includes at least one of the following: remaining usable mileage, remaining service life, and time to reach replacement conditions.

[0242] It is understandable that the remaining service life of the first tire refers to the remaining time until the first tire is scrapped as predicted by theoretical calculation, and the time when the first tire reaches the replacement condition refers to the remaining available time when the first tire may affect the driving safety of the vehicle and needs to be replaced as predicted in combination with actual driving scenarios. The actual driving scenarios may include but are not limited to the purpose of the vehicle (commercial vehicle, family car), the load of the vehicle (truck, bus), the size of the vehicle (large vehicle, medium-sized vehicle, small vehicle), the hardware performance of the vehicle tire, the user's driving habits, driving road conditions, etc.

[0243] Through the embodiments of the present application, tire wear is used to predict tire life information, which can effectively provide users with the current tire health status and health status development trend, allowing users to monitor the health status of vehicle tires at any time, so as to replace or repair tires in time and ensure vehicle driving safety.

[0244] Optionally, the specific implementation of “determining the life information of the first tire according to the wear degree of the first tire” in the above step may be as follows:

[0245] Acquire second information, the second information including the wear of the first tire in a first time period; output life information of the first tire according to the second information and a tire life prediction model, the tire life prediction model being used to characterize the relationship between the historical wear of the tire and the tire life.

[0246] It can be understood that the second information serves as the input of the tire life prediction model, and the life information of the first tire serves as the output of the tire life prediction model. The tire life prediction model is used to characterize the relationship between the historical tire wear and the tire life, and its training process is not limited in the embodiment of this application.

[0247] In the embodiment of the present application, the historical wear within the first time period is used to predict the life information of the tire, which can effectively provide the user with the current tire health status and health status development trend, so that the user can monitor the health status of the vehicle tires at any time, so as to replace or repair the tires in time and ensure the safety of vehicle driving.

[0248] Optionally, the second information may also include but is not limited to at least one of the following:

[0249] The braking strength of the vehicle's brake pedal in the first time period, the braking distance of the first tire in the first time period, and the weather information in the first time period.

[0250] Specifically, in addition to the historical wear, the second information may also include but is not limited to the braking strength of the vehicle's brake pedal in the first time period, the braking distance of the first tire in the first time period, weather information in the first time period, and the like.

[0251] Through the embodiments of the present application, by combining actual driving scenarios and historical wear to predict tire life information, the current tire health status and health status development trend can be effectively provided to users, allowing users to monitor the health status of vehicle tires at any time, so as to replace or repair tires in time and ensure vehicle driving safety.

[0252] Optionally, the second information may also include but is not limited to the accumulated mileage of the current tire, the accumulated usage time of the current tire, the purpose of the vehicle (commercial vehicle, family car), the load of the vehicle (truck, bus), the size of the vehicle (large vehicle, medium-sized vehicle, small car), the hardware performance of the vehicle tires, the user's driving habits, driving road conditions, etc.

[0253] In a possible embodiment, the vehicle tire monitoring method may also include but is not limited to the following steps:

[0254] The display of the wear degree of the first tire and / or the life information of the first tire is controlled.

[0255] Specifically, after the wear degree of the first tire is determined, the display of the wear degree of the first tire may be controlled, and / or the display of the life information of the first tire may be controlled.

[0256] It can be understood that in one possible case, after the remote server determines the wear degree of the first tire and / or the life information of the first tire, it controls the wear degree of the first tire and / or the life information of the first tire to be displayed on a device with a display function such as the vehicle-side computer / mobile phone APP / smart wearable device, etc. In this case, the remote server is independently deployed outside the vehicle, and there is a wireless communication connection between the remote server and the vehicle-side computer / mobile phone APP / smart wearable device, etc. with a display function.

[0257] In another possible case, the remote server is integrated with the vehicle, and after the vehicle determines the wear degree of the first tire and / or the life information of the first tire, the wear degree of the first tire and / or the life information of the first tire are displayed. Through the embodiment of the present application, the display of the wear degree of the first tire and / or the life information of the first tire is controlled, which can effectively provide the user with the current tire health status and health status development trend, so that the user can monitor the health status of the vehicle tire at any time, so as to replace or repair the tire in time and ensure the driving safety of the vehicle.

[0258] Optionally, the wear degree of the first tire and / or the life information of the first tire may be displayed on the vehicle computer interface, or the wear degree of the first tire and / or the life information of the first tire may be sent to a mobile phone or a smart wearable device or other device connected to the vehicle computer, for example, by prompting the user through a screen, sound, light, electricity, vibration, etc.

[0259] In a possible embodiment, the vehicle tire monitoring method may also include but is not limited to the following steps:

[0260] Evaluation information corresponding to the first tire is output according to the wear degree of the first tire and / or the life information of the first tire.

[0261] The evaluation information includes at least one of the following: health status of the first tire, wear condition of the first tire, quality evaluation of the first tire, and use cost evaluation of the first tire.

[0262] Through the embodiments of the present application, the output tire evaluation information can provide users with tire quality and cost evaluation analysis to reduce the maintenance cost of vehicle tires and ensure vehicle driving safety.

[0263] See also Figure 3 , Figure 3 A schematic diagram of a process for calculating tire wear provided in an embodiment of the present application. It can be understood that the steps in the embodiment of the present application can be regarded as the above Figure 2 or, it can be understood that the method for calculating tire wear in the embodiment of the present application can also be regarded as an embodiment that can be executed independently, and the present application does not limit this.

[0264] The method for calculating tire wear provided in the embodiment of the present application is applied to the field of connected vehicle technology, such as calculating tire wear of smart electric vehicles or smart electric bicycles. Specifically, the method for calculating tire wear includes but is not limited to the following steps:

[0265] First, a driving data segment of the vehicle is obtained, which includes but is not limited to the vehicle speed and the wheel speeds of all the vehicle tires. For example, taking a vehicle with four tires (left front wheel, right front wheel, left rear wheel, right rear wheel) as an example, the driving data segment includes but is not limited to the vehicle speed, left front wheel speed, right front wheel speed, left rear wheel speed, and right rear wheel speed.

[0266] Driving data segments (including the above vehicle speed and wheel speed data) with a vehicle speed greater than a certain threshold (configurable, such as 40 km / h) and tire pressure within a normal range (configurable, such as 2.0-3.5 bar) are extracted as valid data segments for calculating tire wear.

[0267] Optionally, when extracting valid data segments, a screening condition can be added: each wheel speed in the valid data segment should be within a preset interval, and the endpoint value of the interval can be configured according to the wheel speeds of all tires of the vehicle, which is not limited in the embodiment of the present application. For example, each wheel speed in the valid data segment should be within [P-3*Q, P+3*Q], where P is the average wheel speed corresponding to all tires of the vehicle, Q is the standard deviation of the wheel speed corresponding to all tires of the vehicle, and 3 is the coefficient of the tire configuration. Optionally, the coefficient is associated with factors such as the hardware performance of the tire, the user's driving habits, and driving road conditions.

[0268] Convert the extracted speed data (kilometers per hour: km / h) into rotation speed data (rotations per minute: rpm). The conversion method can refer to the above Figure 2 The relevant descriptions of formula (1) and formula (2) in the vehicle tire monitoring method shown are not repeated here.

[0269] The tire wear is calculated based on the speed data converted from the vehicle speed and wheel speed. The wear in the embodiment of the present application is defined as the average relative error of the tire effective speed relative to the standard tire speed. The calculation method can refer to the above Figure 2 The relevant descriptions of formula (3), formula (4) and formula (5) in the vehicle tire monitoring method shown are not repeated here.

[0270] Optionally, the degree of wear can be further converted into a health score (such as 0-100), or a health grade (such as excellent, good, poor), as well as the remaining mileage of the tire and other values ​​indicating the health status.

[0271] Finally, the degree of wear or alarm is displayed. For different wear patterns of each tire, different alarm types and corresponding recommended processing methods are output accordingly.

[0272] For details, please refer to Figure 4A and Figure 4B , Figure 4A and Figure 4B A schematic diagram of tire wear provided in an embodiment of the present application.

[0273] like Figure 4A As shown, the wear change curves of the left front wheel (FL), the right front wheel (FR), the left rear wheel (RL), and the right rear wheel (RR) over time are respectively given. The horizontal axis of the curve graph represents time, the left vertical axis represents wear, and the right vertical axis represents tire pressure. The solid line represents the wear change of the tire over time, and the dotted line represents the tire pressure change over time.

[0274] It can be seen that the tire pressure of each tire maintains roughly the same change, but the wear of the left front wheel (FL) deteriorates too quickly compared to other tires. It can be considered that the single wheel is excessively worn, and an alarm may be generated: The left front wheel is worn too quickly, please check it in time.

[0275] like Figure 4B As shown, the wear change curves of the left front wheel (FL), the right front wheel (FR), the left rear wheel (RL), and the right rear wheel (RR) over time are respectively given. The horizontal axis of the curve graph represents time, the left vertical axis represents wear, and the right vertical axis represents tire pressure. The solid line represents the wear change of the tire over time, and the dotted line represents the tire pressure change over time.

[0276] It can be seen that the wear degree of the left front wheel (FL) and the right front wheel (FR) are both less than -0.5, which means that the two wheels are excessively worn, and an alarm can be issued: the left front wheel and the right front wheel are excessively worn, please replace them in time. Or, if the front and rear wheels are evenly worn, a reminder can be issued to remind the user to replace the front and rear wheels.

[0277] Optionally, the tire failure mode may include excessive wear of a single tire, excessive wear of multiple tires, abnormal four-wheel alignment parameters, etc. Accordingly, the recommended processing methods include recommending replacement of tires at a specified position, recommending tire swapping at a specified position, recommending four-wheel alignment testing, etc.

[0278] Optionally, the wear of each tire can be further integrated to output the evaluation and analysis conclusion of the tires of the entire vehicle, for example, the vehicle tires are healthy, please continue to use them.

[0279] Through the embodiment of the present application, the wear degree of the vehicle tire can be determined only by using the vehicle speed and wheel speed data. Compared with the method of using a measuring tool to directly measure the tire pattern to determine the wear degree of the vehicle tire, the embodiment of the present application can use the vehicle speed and wheel speed data to determine the wear degree of the vehicle tire at any time, and monitor the health status of the vehicle tire at any time; compared with the method of indirectly calculating the degree of tire wear by measuring the corresponding torque, slip rate and other parameters through special sensors, the embodiment of the present application can determine the degree of wear of the vehicle tire only based on the sensors for measuring the vehicle speed and wheel speed that are conventionally configured on the vehicle without installing special sensors, thereby reducing vehicle costs.

[0280] See also Figure 5 , Figure 5 A schematic diagram of a process for predicting tire life provided in an embodiment of the present application. It can be understood that the steps in the embodiment of the present application can be regarded as the above Figure 2 or, it can be understood that the method for predicting tire life in the embodiment of the present application can also be regarded as an embodiment that can be executed independently, and the present application does not limit this.

[0281] The method for predicting tire life provided in the embodiment of the present application is applied to the field of connected vehicle technology, such as the life prediction of vehicle tires of smart electric vehicles or smart electric bicycles. The core idea is to use a regression method to construct a tire life prediction model based on the daily calculated wear and related feature data to estimate the remaining service life and replacement time of the tire. Specifically, the method for predicting tire life includes but is not limited to the following steps:

[0282] First, daily characteristic data is extracted, including but not limited to daily wear, current tire accumulated mileage, current tire accumulated calendar time, braking data segment extracted based on vehicle status and brake pedal travel status during the day's driving segment, braking intensity, braking distance, weather information of the day based on timestamp, and vehicle purpose (urban operation, mine, port, etc.).

[0283] Using the characteristic data of the recent historical period (configurable, such as 1 month or 2 weeks, etc.) of vehicles of the same model and purpose, a regression method is used to build a prediction model for tire wear. The extracted characteristic data of the past month (configurable) is input into the prediction model, and the time prompt when the wear reaches the replacement threshold is output.

[0284] Users can query the prediction results on devices with display functions such as the vehicle computer / mobile phone APP / smart wearable devices, and view the current health of the tire and predicted information, including but not limited to: the remaining mileage, remaining service life, and the time to reach replacement conditions.

[0285] It is understandable that the remaining service life of the first tire refers to the remaining time until the first tire is scrapped as predicted by theoretical calculation, and the time when the first tire reaches the replacement condition refers to the remaining available time when the first tire may affect the driving safety of the vehicle and needs to be replaced as predicted in combination with actual driving scenarios. The actual driving scenarios may include but are not limited to the purpose of the vehicle (commercial vehicle, family car), the load of the vehicle (truck, bus), the size of the vehicle (large vehicle, medium-sized vehicle, small vehicle), the hardware performance of the vehicle tire, the user's driving habits, driving road conditions, etc.

[0286] Optionally, the prediction information may also include but is not limited to: current health, health change trend, estimated tire replacement time, current tire accumulated mileage, current tire calendar time, remaining tire service life days / kilometers, etc.

[0287] For example, in Figure 5 A display example is given in , which shows the following forecast information: the current cumulative mileage is 30,000 kilometers, the current calendar time is 200 days, the current health is 95, the remaining days of use are 1,000 days, and the health change trend is attached.
