Automobile side-turning proof safety system

Abstract

The invention relates to a rollover prevention safety system of motor vehicle, which discloses an assistant safety system of motor vehicle for preventing rollover in high-speed turning, belonging to the motor vehicle safety control system technology field. The rollover prevention safety system can make vehicle adjust vehicle gravity center automatically in high-speed turning and decrease the centrifugal force needed in vehicle turning so that the turning radius can be decreased and it is safer and more reliable in high-speed turning of vehicle. The invention can be realized by the following project. Hydraulic adjusting system of rollover prevention and hydraulic power turning machine are connected on hydraulic pump in parallel; when the speed achieves more than the certain value, open-close of corresponding electromagnetic valve is adjusted; when vehicle is turning, open-close of corresponding electromagnetic valve is adjusted to achieve the purpose of adjusting vehicle gravity center in high-speed turning. The rollover prevention safety system of motor vehicle in invention can be applied in various motor vehicles and it has a very good market applicable prospect.

Description

technical field [0001] The invention relates to an anti-rollover safety system for a motor vehicle, in particular to an auxiliary safety system for preventing rollover of a motor vehicle during high-speed turning, and belongs to the technical field of motor vehicle safety control systems. Background technique [0002] At present, when a motor vehicle is turning, the steering wheel drives the steering link through the hydraulic power steering gear, and the steering link drives the differential to pull the inner and outer wheels to form a certain angle and reach the turn through the speed difference of the wheels. When the vehicle speed is low , during the steering process, the speed difference between the inner and outer wheels is also smaller, the centrifugal force is smaller, and the motor vehicle is easier to turn according to the predetermined trajectory; The inner wheels are relatively stationary relative to the outer wheels. At this time, the entire vehicle body is movi...

Problems solved by technology

[0002] At present, when a motor vehicle is turning, the steering wheel drives the steering link through the hydraulic power steering gear, and the steering link drives the differential to pull the inner and outer wheels to form a certain angle and reach the turn through the speed difference of the wheels. When the vehicle speed is low , during the steering process, the speed difference between the inner and outer wheels is also smaller, the centrifugal force is smaller, and the motor vehicle is easier to turn according to the predetermined trajectory; The inner wheels are relatively stationary relative to the outer wheels. At this time, the entire vehicle body is moving in a circle relative to the inner wheels, and the centrifugal force will be greater. The turning radius of the motor vehicle is larger, and it is difficult to turn according to the predetermined trajectory. It is easy to cause rollover or crash accidents. Such traffic accidents are often encountered in real life. The root cause is that when turning at high speed, the centrifugal force is large, and the required turning radius is large. When turning sharply, the turning radius is forced to be reduced. prone to such traffic accidents
