Automobile tire burst safety and stability control system

Abstract

The invention relates to an automobile tire burst safety and stability control system which is used for the manned and unmanned vehicles, is based on a vehicle braking, driving, steering and suspension system, and belongs to the field of automobile tire burst safety. According to the system, the tire burst judgment for detecting the tire pressure, the state tire pressure and the steering mechanical state mode is determined, and an automobile tire burst safety and stability control mode, model and algorithm and a control structure and process are adopted; based on the tire burst state points, the vehicle braking, driving, steering, steering wheel rotating force and suspension balance control is coordinately carried out through the tire burst control entering and exiting and the normal and tire burst control mode conversion, so that the tire burst control of the overlapped real or non-real tire burst processes is achieved. Under the condition that the tire burst process state, the tire burst wheel and the vehicle motion state are sharply changed, the important technical barriers that the wheels and vehicles are seriously unstable due to tire burst, the tire burst extreme state is difficult to control and the like are broken through, and the important problem puzzling the automobile tire burst safety for a long time at present is solved.

Description

technical field [0001] The invention belongs to the field of automobile tire blowout safety Background technique [0002] Car tire blowout, especially on the expressway, is a vicious accident with high risk and high probability of occurrence. Car tire blowout safety is a major topic that has not yet achieved effective breakthroughs at home and abroad. Relevant technical literature retrieval It shows that the current technical solutions for this subject mainly include the following. First, Tire Pressure Monitoring System (TPMS). As a relatively mature tire pressure detection technology, this system is widely used in various vehicles. Relevant tests and technologies have shown that with the help of tire pressure monitoring, the probability of tire blowout can be reduced, but There is no strict corresponding relationship between tire blowout, tire pressure, and temperature-related parameters in the space-time domain, so TPMS cannot truly, real-time, and effectively solve the s...

Problems solved by technology

Its four, automobile tire blowout safety control system and system (Chinese Patent No. 200810119655.5), this invention proposes a kind of technical scheme that "makes the vehicle maintain the original driving direction" by "steering auxiliary motor control", this scheme has no effect on the original tire blowout vehicle. The direction control has a certain effect. In the actual control process, only the original direction of the vehicle is controlled, and it is difficult to achieve the purpose of safe and stable control of the vehicle tire burst.

Fifth, tire blowout brake control system and system (Chinese Patent No. 201310403290), the system and system proposes a wheel brake control system through the difference signal of vehicle tire blowout and non-blowout wheel brake anti-lock control technical solution, but the braking force involved in this solution does not take into account related technical problems and solutions such as wheel vehicle stability control, so it is difficult to achieve the purpose of vehicle tire burst safety control
