Problems solved by technology
However, in the process of driving, the ground environment is always in the process of changing, resulting in the friction between the tire and the ground is always in a changing state, and the rotation speed of the tire will also affect the friction between the tire and the ground, resulting in the friction between the tire and the ground. The friction of the tire is not easy to measure, which makes the wear of the tire impossible to estimate
[0004] At present, in order to solve the problem of tire wear monitoring, most of the drivers visually observe the change of tire thickness, or use a variety of monitoring instruments to monitor the change of tire thickness and use complex calculation of tire wear, but the effect is mostly not good

The invention discloses a tire wear amount detection method, device, equipment and non-volatile storage medium. The method includes: taking a fixed duration as the unit, dividing the driving journey into a plurality of driving sections, and installing them in each tire pressure gauge of the automobile tires. The sensor obtains the tire pressure data, temperature data and rotational speed data at multiple moments in the driving section, and quantifies and obtains the average tire pressure, temperature and rotational speed; based on the rotational speed data and the rotational speed average and the pre-built friction coefficient factor model Match to obtain the corresponding friction coefficient factor, import the average tire pressure and the average temperature into the pre-built calculation model to calculate the first friction coefficient, and multiply the first friction coefficient and the friction coefficient factor to obtain the second friction coefficient Coefficient; calculate the tire wear amount of the driving segment based on the second friction coefficient, the predetermined specification data of the tire, the fixed duration and the average tire pressure, and accumulate the wear amount of multiple driving segments to obtain the tire L.
Description
technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a tire wear amount detection method, device, electronic equipment and non-volatile storage medium. Background technique [0002] Tire is one of the necessary parts of the car. During the driving process, the tire is in a state of wear. When it is worn to a certain extent, the tire is prone to air leakage, slippage and even explosion due to various internal or external reasons, resulting in a driving accident. It threatens the safety of cars and even the personal safety of passengers, so the degree of tire wear is one of the issues that car drivers must pay attention to. [0003] As the tires are in contact with the ground, the friction between the tires and the ground wears down the tires. However, during the driving process, the ground environment is always in the process of changing, which causes the friction between the tire and the ground to be always in a state...
