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 abrasion loss detection method, device and equipment and a nonvolatile storage medium. The method comprises the following steps of dividing a driving travel into a plurality of driving sections by taking a fixed duration as a unit, acquiring tire pressure data, temperature data and rotating speed data at a plurality of moments in the driving sections by each tire pressure sensor arranged on an automobile tire, and quantitatively acquiring a tire pressure mean value, a temperature mean value and a rotating speed mean value; matching with a pre-constructed frictioncoefficient factor model based on the rotating speed data and the rotating speed mean value to obtain a corresponding friction coefficient factor, importing the tire pressure mean value and the temperature mean value into a pre-constructed calculation model to calculate a first friction coefficient, wherein the first friction coefficient is multiplied by the friction coefficient factor to obtaina second friction coefficient; and based on the second friction coefficient, the predetermined specification data of the tire, the fixed duration and the tire pressure mean value, calculating the tireabrasion loss of the driving sections, and accumulating the abrasion loss of the plurality of driving sections to obtain the tire abrasion loss.
Description
technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a tire wear detection method, device, electronic equipment and non-volatile storage medium. Background technique [0002] Tires are one of the necessary parts of a car. During driving, the tires are in a state of being worn out. When worn to a certain extent, the tires are prone to air leakage, skidding or even explosion due to various internal or external reasons, resulting in driving accidents. Threat to the safety of the car and even the personal safety of the occupant, so the degree of wear of the tire is one of the problems that the driver 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. But 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, a...
