Abstract
The invention discloses a kind of braking tire pressure control system, belong to field of automobile control.The method includes：Tire pressure monitoring circuit, vent valve, charge valve, tire pressure governor motion, brake monitoring circuit, control circuit.During application, brake monitoring circuit real-time monitoring vehicle brake condition, when monitoring vehicle braking, control circuit controls vent valve to open, bleed a tire and lead to pressure drop, tire is increased with the contact area on ground, increases the frictional force between tire and ground, and then reaches the purpose shortening braking distance.After brake monitoring circuit monitoring is cancelled to vehicle braking, control circuit controls the work of tire pressure governor motion, charge valve is opened simultaneously, it is inflated to tire, after tire pressure monitoring circuit measuring tire pressure returned within normal range, control circuit controls tire pressure governor motion to quit work, and charge valve is closed, and so that tyre inner pressure is maintained in normal range.
Description
Technical field
The present invention relates to a kind of vehicle control electronics product, specifically, it is related to a kind of control vehicle in braking procedure
The device of tire pressure size.
Background technology
At present, tire pressure monitoring system has been widely used, and its purpose is primarily to the pressure of real-time monitoring vehicle tyre
Force value is it is ensured that the safety in vehicle travel process and power conservation requirement.For different vehicle tyres, vehicular manufacturer all can advise
Pressure limit during its normal use fixed.If it is known that tire pressure is excessive, can there is the danger blown out in the process of moving
Danger；And tire pressure is too small, it will increase the contact area between tire and ground, increasing friction force, lead to fuel consumption significantly
Increase.At present, the normally-pressured neighbor that vehicular manufacturer specifies, has taken into account safety and the fuel economy of tire, but car
In the process of moving, when such as running into brake condition, shorten braking distance as far as possible and be to ensure that passengers inside the car and vehicle safety itself
Important method.Current practical situation is that tire pressure when tire pressure during braking and normally travel can't occur
Change, thus actively do not increase the contact area between tire and ground in braking procedure, frictional force does not occur bright yet
Aobvious increase, braking distance can't be significantly increased.
Content of the invention
The problem to be solved in the present invention is to provide the dress in a kind of braking procedure in vehicle, tire pressure is controlled
Put, when vehicle is braked, reduce tire pressure, the contact area on tire and ground when increasing braking, thus shorten braking distance.
When tire pressure is too low, tyre explosion equivalent risk can be increased, so it is ensured that tire pressure while reducing tire pressure
Within being in default minimum pressure scope, shorten and while braking distance, ensure tire and vehicle safety.After braking is cancelled,
Can be by tire pressure governor motion to tyre inflating, within making tire pressure return to normal range.
Brief description
Fig. 1 is the workflow diagram that the present invention is explained.
Specific embodiment
For achieving the above object, the technical solution adopted in the present invention is：A kind of braking tire pressure control system, including tire pressure
Observation circuit (1), vent valve (2), charge valve (3), tire pressure governor motion (4), brake monitoring circuit (5), control circuit (6).
During application, in normal vehicle operation, brake monitoring circuit (5) real-time monitoring vehicle brake condition, when detecting
During vehicle braking, control circuit (6) controls vent valve (2) to open, and bleeds a tire and leads to pressure drop, the contact with ground for the tire
Area increases, and increases the frictional force between tire and ground, and then reaches the purpose shortening braking distance.
Meanwhile, tire pressure monitoring circuit (1) real-time monitoring tire pressure, when vent valve (2) is opened, tire pressure monitoring circuit
(1) whether detection tire pressure is reduced to default minimum pressure scope, when tire pressure is reduced to default minimum pressure scope, controls
Circuit (6) controls vent valve (2) to close, and stops venting, so that tire pressure is maintained in the range of default minimum pressure.
After brake monitoring circuit (5) detects vehicle braking and cancels, control circuit (6) controls tire pressure governor motion (4)
Work, charge valve (3) is opened simultaneously, is inflated to tire.
After tire pressure monitoring circuit (1) measurement tire pressure returned within normal range, control circuit (6) controls tire pressure to adjust
Section mechanism (4) quits work, and charge valve (3) is closed, and so that tyre inner pressure is maintained in normal range.
