Tire burst safety suspension system, control method and vehicle

Abstract

The invention provides a tire burst safety suspension system, a control method and a vehicle. The tire burst safety suspension system comprises an air spring, a high pressure gas generating device, atire pressure detecting device and a control unit, wherein the high pressure gas generating device is connected with an air chamber of the air spring; the tire pressure detecting device is connected with a tire and the high pressure gas generating device separately; and the control unit is connected with the tire pressure detecting device. According to the tire burst safety suspension system, thecontrol method and the vehicle, the air spring is internally provided with the high pressure gas generating device, the tire pressure measuring device is internally provided with a cylinder piston, whether tire burst occurs or not at the time is detected through displacement of the cylinder piston, the piston moves to the left to close a switch contact when the tire of a vehicle is burst so that aspark plug in the gas generating device in the air spring is powered to work, the high pressure gas generating device reacts quickly to produce high pressure gas, the tire burst side of the air spring is filled with the high pressure gas in the tire burst moment, thus the heights of a vehicle body on the two sides can be balanced as quickly as possible in a short time, and meanwhile, the stiffness of the air spring can be increased to reduce the risk of roll.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension, and in particular relates to a tire blowout safety suspension system, a control method and a vehicle. Background technique [0002] When a vehicle has a puncture, the height of the body on the side with the puncture is significantly lower than the height of the vehicle on the side where the puncture did not occur, and the roll stiffness of the vehicle on the side with the puncture is significantly reduced. At this time, the vehicle rolls or even rolls over. danger. Therefore, the safety of the vehicle can be improved by controlling the suspension system when the tire blows out. [0003] In the prior art, there is an automobile tire blowout safety control device. When a tire blowout of a vehicle is detected, the steering device is locked and the braking device is controlled to decelerate slowly, so as to ensure that the vehicle can stop smoothly. In the prior art, there is a car ti...
