Automobile tire burst prevention controller on basis of electrical power steering

Abstract

The invention discloses an automobile tire burst prevention controller on the basis of the electrical power steering and relates to an automobile safety control device. The automobile tire burst prevention controller on the basis of the electrical power steering comprises an ECU (Electrical Conversion Unit) processor, a data acquisition part, a data processing part, a tire burst display part, a tire burst alarm part, a motor steering control part, a power supply circuit, an upper communication circuit and a fault diagnosis circuit. In the case of tire burst, the tire burst alarm part is started and tire burst information is displayed by the tire burst display part; a steering wheel is detected whether to steer and a steering direction and a steering angle of the steering wheel are detected by the data acquisition part; if the steering wheel does not steer, a steering system of a vehicle is directly controlled to carry out tire burst prevention control by the motor steering control part; if the steering wheel steers, the steering direction, the steering angle and turning velocity information of the steering wheel need to be detected so as to provide parameters for correcting a steering declination angle, then the steering system of the vehicle is controlled by the motor steering control part, and by controlling the steering system of the vehicle, the vehicle is kept moving in the original driving direction after the tire is burst so that the vehicle is avoided being out of control and being deflected when the tire is burst.

Description

technical field [0001] The invention relates to an automobile safety control device, in particular to an automobile run-flat tire controller. Background technique [0002] When a car tire suddenly blows out, it is easy to run out of control and deviate, causing casualties and property damage accidents. For this reason, the industry has conducted in-depth research on the control technology of car run-flat tires. At present, there are mainly the following kinds of car run-proof tire control technologies: (1) Ultra-flat Tire technology, the core of this technology is to reduce the height of the car tire as much as possible and enhance the support stiffness of the sidewall of the car tire, so that the height of the wheel does not drop significantly after the tire blows out, so as to provide the tire with a relatively low-speed basic driving Performance, the original intention of this technology is to remove the spare tire of the car, not to prevent the car from blowing out, and ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome and solve the shortcoming and problem that existing automobiles are easy to get out of control and run off when the automobile tire suddenly bursts due to the lack of a perfect tire blowout anti-deviation device, causing casualties and property damage accidents. The electric steering car run-flat tire controller can reliably and effectively prevent the car from running off when the car is driving at a medium or high speed and suddenly blows out, and automatically maintain the car in the original driving direction to ensure the safety of the car and prevent Casualties and property damage accidents
