Embodiment Construction

[0024] The structure of the tire and the tire pressure monitoring method will be explained below with reference to the accompanying drawings and embodiments.

[0025] see figure 1 , the tire 100 provided by this application is applied to a vehicle. The inside of the tire 100 is provided with a plurality of piezoelectric film sensors 10 segmented along the circumferential direction of the tire 100 . Each piezoelectric film sensor 10 is used to detect tire pressure information on the segmented area of ​​the tire 100 corresponding to its location.

[0026] Since the piezoelectric film sensor 10 can be powered by the piezoelectric current generated by its own deformation, no external power supply is required. Inconvenient operations such as replacing the battery or charging the battery are omitted, because the tire 100 is inconvenient to open once it is manufactured, and the tire 100 itself will be damaged if opened.

[0027] Specifically, the tire 100 includes a crown 20 , and...

Abstract

A tire pressure monitoring method comprises the steps of collecting tire pressure information when a tire (100) is in contact with the ground during rotation; acquiring a deformation amount of the tire (100) according to the tire pressure information; and calculating Equivalent radius of the tire (100) according to the deformation amount ; and calculating the slip ratio of the tire (100) accordingto the equivalent radius. According to the slip rate, the safety factor of the tire can be understood. For example, when the slip ratio exceeds a preset range, the tire has a low safety factor and needs to be repaired or replaced to reduce the probability of a safety accident. The invention also relates to a tire slip ratio calculation device, a vehicle anti-lock braking system, a vehicle including the system, and a device having storage function.

Description

technical field [0001] The present invention relates to the technical field of tire information monitoring, in particular to a tire monitoring method, a slip ratio calculation device, a system, a vehicle, and a storage device. Background technique [0002] With the development of society, the problem of traffic safety has become a major worldwide problem, and the impact of car safety on human life and property is self-evident. The car is completely locked, or the tire slip rate is too small to cause the car to fail to brake, which can easily cause the car to lose control and cause traffic accidents. Therefore, car safety driving is getting more and more attention. Traditional passive safety is far from being able to avoid traffic accidents, so active safety has been paid more and more attention by everyone. Contents of the invention [0003] Based on the above technical problems, the present invention provides a tire monitoring method, slip rate calculation device, system...
