Problems solved by technology

But the system still has its limitations, for example: the types of vehicles involved are very limited, the PSI system is currently only used in large vehicles such as semi-trailers and military vehicles, and it is still blank in the civilian field, especially cars; in terms of adjustment flexibility , there are also some defects, the system can not adjust the tire pressure of each vehicle; since the driver still needs to manually operate and start, the system has no advantage in the degree of intelligence
In addition, vehicles equipped with the PSI system are equipped with soft inflation ducts connected to the valve cores externally. This device may affect the dynamic balance of the wheels and affect the appearance of the vehicle. There are certain aging problems

Embodiment 1

[0022] Example 1, the working principle of the automatic inflation and deflation tire pressure adjustment device

[0023] When the tire pressure of each wheel hub detected by the pressure sensor 5 is lower than the set tire pressure inflation pressure threshold range, the on-board air pump will automatically start, and directly inflate the tires at a normal speed through the air storage tank and the automatic inflation mechanism; at this time, the air storage The pressure of the tank will not decrease. During the running of the vehicle, the air pump will stop working, and the gas storage tank and the independent control gas distribution system will continue to work, and the tires will be inflated quickly and slightly according to the driving state of the vehicle; the pressure sensor 5 and the micro motor of the electronically controlled valve core 8 14 connection; if the tire pressure of each wheel hub detected by each pressure sensor is higher than the set tire pressure defla...

Embodiment 2

[0025] The dynamic tire pressure adjustment mechanism is served by the central control mechanism of the original vehicle driving ECU; the central control mechanism is connected to the automatic inflation mechanism and the automatic deflation mechanism through the signal line at the same time; it is powered by the vehicle battery. The central control mechanism collects the dynamic status of the vehicle itself (vehicle tire temperature, driving form, mass distribution ratio, adhesion of each wheel, compression or stretching degree of each suspension), driving conditions (driving road conditions, ambient temperature) and various parameters of the vehicle. Tire pressure information, and calculate and analyze vehicle operation data, rely on vehicle sensors to analyze road surface information, and judge road surface conditions; according to the vehicle driving mode and the adhesion data of different wheels, adjust the tire pressure of each tire and automatically adjust the tire pressu...

Abstract

The invention discloses a the technical field of safety regulation and control of vehicle operation and relates to an automatic dynamic tire pressure adjustment system of a vehicle. The tire pressureadjustment system comprises a gas pump mounted at the front part or the rear part of the vehicle, a light gas storage tank connected with the gas pump, and one-way gas valves, hollow sealed half shafts and hollow hubs of a gas distribution system, as well as electric control valve cores and pressure sensors, wherein the one-way gas valves, the hollow sealed half shafts and the hollow hubs are controlled independently; and the electric control valve cores and the pressure sensors are mounted in the hollow hubs. The system adopts a hollow hub design; the use external soft inflation guide tubes connected with the valve core is avoided structurally; an aging risk is effectively reduced; the unsprung mass of the vehicle is effectively reduced; and dynamic balance and appearances of wheels are not influenced. The system adjusts tire pressure of each tire separately, automatically adjusts the tire pressure, enhances performance of the tires, allows the vehicle to be more stable during running, and guarantees safe operation of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of safety regulation and control of vehicle operation, and in particular relates to a vehicle automatic dynamic tire pressure regulation system. Background technique [0002] Some foreign semi-trailers have been installed with PSI tire automatic inflation system. After installing the system, the driver can perform pressure measurement, inflation and deflation of tires in the car, thereby improving the safety, passability and safety of the driver. comfort. But the system still has its limitations, for example: the types of vehicles involved are very limited, the PSI system is currently only used in large vehicles such as semi-trailers and military vehicles, and it is still blank in the civilian field, especially cars; in terms of adjustment flexibility , There are also certain defects, the system cannot differentiate and adjust the tire pressure of each car; since the driver still needs to manually operate a...
