Automobile high-speed tire explosion emergency braking stability control system

Abstract

The invention discloses an automobile high-speed tire explosion emergency braking stability control system, comprising a power source part of an automobile tire explosion emergency braking system, a control part of a tire explosion emergency braking stability system and a hydraulic anti-lock braking part. When a tire explosion signal is monitored by an automobile tire explosion monitoring system, an emergency braking mode is determined according to the tire explosion state (tire explosion target wheel orientation and number of tire explosion wheels) and the automobile motion state; an emergency braking system works to perform automobile automatic brake after tire explosion under the action of a working mode switching valve; and on the basis of a conventional hydraulic ABS hardware, the emergency braking control system unit is used for calculating the automobile motion state, sends an automobile stability control instruction to an ABS control unit to control and regulate the braking pressure in each wheel braking cylinder of an automobile, and ensures that the speed is lowered to a safe speed range until the automobile stops according to an anticipated automobile path as soon as possible. The system in the invention can remedy the delay problem of braking response time of a driver and assist the automobile with exploded tires to realize safe stopping.

Description

technical field [0001] The invention relates to an emergency braking stability control system for a high-speed tire blowout of an automobile. Background technique [0002] A tire blowout is an emergency failure in which the mechanical strength of a certain part of the tire is severely weakened, and the tire pressure loses balance and bursts suddenly. After the tire blows out, the car will have severe sideslip, flick, or even overturn accidents, which will not only endanger the safety of the car with the blown tire, but also cause many cars to collide due to the inability of the passing vehicles to dodge, causing major accidents. traffic accident. Therefore the high-speed tire blowout problem is a technical problem urgently needed to be solved for the high-speed driving safety performance of modern automobiles. [0003] According to relevant technical literature retrieval, the current safety measures for vehicle high-speed tire blowout mainly include the following types: ...

AI Technical Summary

Problems solved by technology

However, the locking of the direction leads to the lack of maneuverability of the vehicle, which cannot balance the huge movement imbalance caused by the tire blowout, and the driver cannot compensate this imbalance through operation, which is easier when the inertia force is large and the vehicle speed is high. Accidents such as rollovers

Therefore, it is rarely used alone as a system

[0007] 4) The emergency inflation device, after monitoring the rapid drop in tire pressure, makes gas by detonating the gunpowder to inflate the spare inner tube of the tire in an emergency, so as to alleviate the instability of the vehicle after the tire blows out (patent number: 200410041316.1), but the explosion-proof design of this technology The tires are different from ordinary tires, the ignition inflation control device is added, and additional weight is added in the tire, causing the tire to be unbalanced

In addition, the misfire of the ignition and inflation control will easily cause the tire to burst, which will bring unsafe factors.

[0008] 5) Through the use of special run-flat tire method to achieve safe driving and braking to stop after a tire blowout, these special run-flat tires have complex structures and high costs, and are rarely installed on general vehicles
