Specifically, fig. 1 is a schematic flow chart of a method for managing wear of a vehicle tire according to an embodiment of the present application.

As shown in fig. 1, the method for managing the wear of the vehicle tire comprises the following steps:

in step S101, motion data of a vehicle is acquired.

It will be appreciated that the motion data in embodiments of the present application may be obtained by an acceleration sensor.

In the actual implementation process, the embodiment of the application can be used for installing the acceleration sensor at the mass center position of the vehicle, and acquiring the motion data of the vehicle through the acceleration sensor, so that the support is provided for standardizing the driving mode of a driver and the maintenance and use mode of a tire.

The embodiment of the application can acquire the motion data of the vehicle, starts working from the initial stage of using the tire, monitors the whole tire using process in real time, and ensures that the following problems of irregular driving and improper use of the tire can be timely reminded.

Optionally, in one embodiment of the application, the motion data includes lateral acceleration and longitudinal acceleration of the vehicle.

It will be appreciated that the lateral and longitudinal acceleration of the vehicle in embodiments of the application may be obtained by an acceleration sensor.

In the actual execution process, the embodiment of the application can acquire the motion data of the vehicle such as the lateral acceleration, the longitudinal acceleration and the like of the vehicle through the acceleration sensor, further monitor the whole tire use process in real time, and ensure that the follow-up problems of irregular driving and improper use of the tire can be timely reminded.

In step S102, the driving severity of the vehicle is calculated from the motion data, and the driving range of the tire is acquired.

It can be understood that the concept of driving severity in the embodiment of the present application is proposed according to the influence factors and characteristics of the tire wear, including an accelerometer for testing the acceleration of the vehicle, a wheel rotation counter, and a module for signal processing and display.

In the actual execution process, the embodiment of the application can calculate the driving severity degree of the vehicle according to the motion data, set the initial mileage used by the vehicle or the tire, and acquire the driving mileage of the tire through superposition of the wheel revolution.

According to the embodiment of the application, the driving mode of a driver and the tire maintenance and use mode are standardized by calculating the driving severity degree of the vehicle and acquiring the driving mileage of the tire, so that the intelligence and the practicability of the vehicle are improved.

Optionally, in one embodiment of the present application, calculating the driving severity of the vehicle from the motion data includes: calculating an average lateral acceleration and an average longitudinal acceleration of the number of wheel revolutions from the lateral acceleration and the longitudinal acceleration of the vehicle; and calculating the driving severity of the vehicle according to the wheel revolution, the average lateral acceleration and the average longitudinal acceleration of the wheel revolution and the preset wheel load coefficient.

It CAN be understood that the number of rotations of the wheel in the embodiment of the application may be the number of rotations of the wheel, where the number of rotations of the wheel may be read through the CAN network, the number of rotations N reflects the accuracy of monitoring, the smaller the number of rotations is, the higher the monitoring accuracy is, but the larger the calculated energy consumption is, the larger the number of rotations is, the lower the monitoring accuracy is, and the N value is properly adjusted according to the use condition (such as plain and mountain land) of the vehicle, so that the effective monitoring CAN be ensured while the calculated energy consumption is reduced.

As a possible implementation manner, the embodiment of the application can calculate the average lateral acceleration and the average longitudinal acceleration after the vehicle rotates for N turns by monitoring the lateral acceleration g _y and the longitudinal acceleration g _x of the vehicle, and then calculate the driving severity DSN of the vehicle according to the number of the wheel revolutions N, the average lateral acceleration and the average longitudinal acceleration after the vehicle rotates for N turns and the wheel load coefficient F _z/F_z,R.

In the embodiment of the application, the abrasion of the tire is influenced by the longitudinal force and the lateral force, wherein the influence of the lateral force on the abrasion of the tire is more prominent than that of the longitudinal force, and the lateral rigidity of the tire is lower than that of the longitudinal rigidity, so that the tire is easy to deform and slide friction under uneven pressure. Therefore, the embodiment of the application can calculate the weight of the lateral force friction work and the longitudinal force friction work according to the ratio of 5:1, and the calculation formula of the driving severity of the vehicle is as follows:

Wherein CSN is steering severity, BSN is driving braking severity, g is acceleration value, y is average lateral acceleration, x is average longitudinal acceleration, F _z and F _z,R are actual wheel load and rated wheel load in wheel load coefficients respectively, and N is total number of revolutions of the tire.

In the actual execution process, the embodiment of the application can identify the driving behavior and the tire using mode of the user according to the driving severity and the driving mileage, and generate a user behavior prompt and/or a use prompt when at least one of the driving behavior and the tire using mode reaches a certain tire rapid wear condition, for example, the embodiment of the application can identify the driving behavior of the user when the driving severity exceeds a preset threshold, and judge that the vehicle meets a certain tire rapid wear condition when the driving behavior of the user is not standard, such as frequent turning and braking of the vehicle, and generate a user behavior prompt at the moment, and standardize the driving behavior by the voice prompt driver; for another example, the embodiment of the application can identify the use mode of the tire when the driving mileage is 11000km, and judge that the vehicle meets a certain tire rapid wear condition when the tire is improperly used, such as the load and power arrangement of the front and rear axles of the vehicle are different, at this time, can generate a user use prompt, and send a text prompt to a mobile phone client of a driver or display the text prompt on an instrument panel through the vehicle so as to prompt the user to adjust the use mode of the tire.

In the actual execution process, the embodiment of the application can compare the driving severity degree DSN with the threshold value K, and when the driving severity degree is larger than a certain threshold value, the driving behavior of the driver is judged to be high-strength behavior.
