Abstract

The invention relates to a tire pressure detection method and device. The method includes the steps that the wheel speed of each tire in the running process of a vehicle is obtained; the wheel speed accumulated value of each tire within a preset time period is calculated according to the obtained wheel speed; the calibrated wheel speed value of each tire is determined according to the wheel speed accumulated value of the corresponding tire and the corresponding wheel speed calibration factor of the corresponding tire, wherein the wheel speed calibration factors are calibration factors which are stored in advance and used for calibrating the wheel speeds of all the tires meeting the calibration condition to be the unified wheel speed; the difference value of the maximum calibration wheel speed value and the minimum calibration wheel speed value is compared with a preset alarm threshold value; and the tire pressure state of the vehicle is judged according to the comparison result. By the adoption of the method and device, cost can be saved, and meanwhile the tire pressure detection accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of detection, in particular to a tire pressure detection method and device. Background technique [0002] Tire pressure is the air pressure inside the tire, which can be simply called tire pressure. Too high or too low air pressure will shorten the service life of the tire. When the tire air pressure is higher than a certain threshold, the tire is in an over-inflated state, and when the tire air pressure is lower than a certain threshold, the tire is in an under-inflated state. If the tire pressure is too low, the deformation of the carcass will increase, and the sidewall will be prone to cracks. At the same time, flexion will occur, resulting in excessive heating, aging of the rubber, fatigue of the ply, and breakage of the cord. It will also increase the ground contact area of ​​the tire and accelerate Wear and tear on the tire shoulders may also cause safety accidents. If the tire pressure is ...
