Abstract
The invention relates to an automobile anti-lock braking system with an innovative parameter fed back and controlled in real time, and belongs to the technical field of automobile anti-lock braking systems. The automobile anti-lock braking system with the innovative parameter fed back and controlled in real time solves the technical problems that a current automobile anti-lock braking system is the braking system using control over the automobile slip rate as the principle, so that braking energy and braking opportunities are wasted, and the ideal feedback according to the actual situation of a road surface friction coefficient can not be achieved as well. By means of the automobile anti-lock braking system with the innovative parameter fed back and controlled in real time, the waste problems are solved, and by the way of real-time feedback and control of the key parameter, namely tire pressure for automobile stabilization in times of emergency braking, compared with an existing automobile anti-lock braking system, more friction opportunities and braking energy can be provided for automobile wheels on the premise that the automobile wheels do not jump off the ground.
Description
Technical field: anti-blocking brake system of automobile.
, there is the waste on braking energy and the opportunity of braking in technical background: current anti-blocking brake system of automobile is to control the brake system that drift out rate is principle, can not produce for the actual state of surface friction coefficient desirable feedback.
Summary of the invention
As shown in the figure, schematic diagram 1 is braking front vehicle wheel state, and V is automobile direct of travel, and ground is in the face of the friction force of tire during for braking for f1, and f2 is that the tire front side that causes of f1 is stressed.H1 is the distance of braking front vehicle wheel axle center to ground, the antiblock device braking rear wheel state that schematic diagram 2 is, and h2 is the distance of braking rear wheel axle center to ground.The wheel automotive wheels liftoff vehicle body reason place out of control that causes suddenly of stopping when dead as can be seen here.
Existing ABS anti-blocking brake system of automobile, by controlling drift out rate, does not stop extremely wheel, and tire pressure cyclic fluctuation all the time between Fig. 2 and Fig. 1, and does not reach the peak state of Fig. 2, thereby makes wheel not jump out of ground.The existing ABS anti-blocking brake system of automobile brake system more locked than pure machinery played better braking effect, but has braking energy and the waste on the opportunity of braking, can not produce for the actual state of surface friction coefficient desirable feedback.
The anti-blocking brake system of automobile of this patent innovation parameter Real-time Feedback and control, solved above-mentioned waste problem, the key parameter of vehicle steadily when to emergency braking---tire pressure Real-time Feedback and control, automotive wheels is not being jumped out of under the prerequisite on ground, than existing ABS anti-blocking brake system of automobile, can give wheel with more frictions opportunitys, more braking energys.That is, during emergency braking, first wheel moment is stopped extremely, or moment produce higher slip rate, now f1 increases f2 and increases thereupon, tire pressure increases thereupon, tire produces the trend changing from Fig. 1 to Fig. 2.This patent system is monitored inside tires pressure by tyre pressure sensor, arrives critical pressure moment or slightly shifts to an earlier date certain hour release portion braking force, makes f1 reduce f2 and reduces thereupon, inside tires pressure decreased, the energy of absorption tire take-off.Start again subsequently braking, move in circles, give wheel with more frictions opportunitys, more braking energys, reach than the better braking effect of existing ABS anti-blocking brake system of automobile.Meanwhile, to there being the car of active suspension system, can by active suspension system, repeatedly absorb the energy of tire pressure rising take-off, under the prerequisite that makes not takeoff at wheel, allow moment to produce higher slip rate or wheel dead time of stopping is extended more.In addition, because the substantive meaning of parameter, this patent brake mode all can produce real-time optimum braking effect on upper different coefficients of friction road surface.Accompanying drawing explanation: Fig. 1 is braking front vehicle wheel constitution diagram;
Fig. 2 is without antiblock device braking rear wheel constitution diagram.
Claims (2)
1. take the anti-blocking brake system of automobile of tire pressure as principal parameter Real-time Feedback and control.
2. the antiblock device of active suspension system under coordinating.
