Automobile tire blew-out safety and stability control system

Abstract

The invention discloses an automobile tire blew-out safety and stability control system for manned and unmanned vehicles, is based on vehicle braking, driving, steering and suspension systems, and belongs to the field of automobile tire blew-out safety. The system establishes the tire blew-out determination of tire pressure detection, a state tire pressure and a steering mechanics state mode, andadopts an automobile tire blew-out safety and stability control mode, a model, an algorithm, a control structure and a flow; based on tire blew-out state points, through conversion of tire blew-out control entering and exit and normal and tire blew-out control modes, vehicle braking, driving, steering, steering wheel rotation force and suspension balance control are coordinately conducted, the real or non-real tire blew-out process overlapped tire blew-out control is achieved; under the conditions of rapid changes of the tire blew-out process state and the movement state of blew-out tires andvehicles, technical barriers such as severe instability of the tires and the tire blew-out, the difficulty in controlling the extreme state of the tire blew-out and the like are broken through, and the system solves the major problem which long plagues the automobile tire blew out safety.

Description

Technical field [0001] The invention belongs to the field of car puncture safety Background technique [0002] Car punctures, especially car punctures on highways, are a very dangerous and highly probable malignant accident. Car puncture safety is a major issue 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, the tire pressure monitoring system (TPMS), as a relatively mature tire pressure detection technology, is widely used in various vehicles. Related tests and technologies show that with the help of tire pressure monitoring, the probability of tire bursts can be reduced, but There is no strict correspondence between tire blowout and tire pressure and temperature-related parameters in the tire in the space-time domain. Therefore, TPMS cannot truly, real-time and effectively solve the safety problems of car tire blowout...

AI Technical Summary

Problems solved by technology

Its four, automobile tire blowout safety control method 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 method (Chinese Patent No. 201310403290), the system and method propose a method of wheel brake control 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
