Tire gauge and tire pressure detection control method

Abstract

The invention discloses a tire gauge and a tire pressure detection control method. The method comprises the following steps that a control unit of the tire gauge detects the current driving speed in real time or regularly through an acceleration sensor; the control unit selects a preset low-speed mode or a high-speed mode according to the driving speed so as to correspondingly set the tire pressure detection interval time as a longer time slot or a shorter time slot; and the control unit is used for acquiring tire pressure data used for outputting display according to a time slot limited by the tire pressure detection interval time. The real-time driving speed is obtained through the acceleration sensor, the control unit correspondingly selects the corresponding tire pressure detection frequency and the frequency of sending the tire pressure data to an automobile host through the driving speed and the obtained tire pressure data to adjust the work of the tire gauge, and then the tire gauge can work dynamically. Therefore, the electric quantity of the tire gauge is saved, the detection frequency of the tire pressure is higher under the condition of high speed, and tire faults can bequickly reflected.

Description

technical field [0001] The invention belongs to the technical field of vehicle detection, and in particular relates to a tire pressure detection control method. Background technique [0002] Tire pressure detection refers to the real-time detection of tire pressure during driving, and feedback of tire leakage, under-pressure, over-pressure, etc. to the driver to ensure driving safety, which plays a very important role in actual vehicle applications . [0003] At present, the tire pressure is mainly detected by a tire pressure sensor, which is usually installed in the tire to accurately detect the tire pressure. However, the tire pressure sensor is powered by a battery. When the tire pressure sensor is installed in the tire, it is difficult to remove the tire pressure sensor from the tire to replace the battery. At the same time, it takes a lot of time for the tire pressure sensor to detect the tire pressure and send the tire pressure information to the car host. As a resul...

Problems solved by technology

However, the frequency of tire pressure detection and the frequency of sending tire pressure information to the car are mostly fixed, and cannot be adjusted according to the driving speed, tire pressure data and other information, which will still lead to waste of power in the tire pressure sensor, and cannot further save power. Extend the working hours of the tire pressure sensor in the tire
