Automatic inflation and deflation system and method for vehicle tires

Abstract

The invention discloses an automatic inflation and deflation system for vehicle tires. The automatic inflation and deflation system comprises a tire pressure monitoring device, an air pressure supercharging device, a control valve, a distribution valve, a control device and a plurality of connection pipes, wherein the tire pressure monitoring device is used for monitoring tire information of a vehicle and sending the tire information to the control device; when pressure in a tire is insufficient, the control device controls the air pressure supercharging device to be turned on, controls a first work position of the control valve to be conducted, and also controls a valve of the distribution valve corresponding to the tire with insufficient air pressure to be opened for inflation; when the tire pressure is too high, the control device controls the air pressure supercharging device to be turned off, controls a second work position of the control valve to be conducted, and also controls the valve of the distribution valve corresponding to the tire with excessive air pressure to be opened for deflation. The automatic inflation and deflation system for vehicle tires can conveniently and rapidly complete automatic inflation and deflation of tires; the invention further relates to an automatic inflation and deflation method for vehicle tires.

Description

technical field [0001] The invention relates to the field of automobile driving safety, in particular to a vehicle tire automatic inflation and deflation system and method. Background technique [0002] As we all know, the change of automobile tire pressure directly affects the level of automobile fuel consumption, the degree of tire wear and even related to automobile driving safety. When the tire pressure is lower than the standard requirement, due to the low tire pressure, the sinkage of the wheel increases, the radial deformation of the tire increases, the friction between the tread and the ground increases, the rolling resistance increases, and the internal stress of the carcass decreases. As it rises, the temperature of the carcass rises sharply; the tread rubber is wavy and bends rapidly, and the rubber becomes soft over time, causing the tire to age rapidly, causing local delamination of the carcass and increased tread wear. In this case, if the car continues to run...

Problems solved by technology

[0004] Although the current tire pressure monitoring device can detect the tire pressure status in real time and remind the driver, when the tire pressure alarm signal is detected, it cannot timely replenish the pressure of the low pressure tire, and also cannot deflate the high pressure tire. to press

When replenishing pressure, it is necessary to carry the tire inflation device with you, and complete self-inflation through a series of actions such as an external battery, especially if the tire pressure is insufficient on the highway, the risk of self-inflation when parking on the highway is very high
