Abstract
The invention discloses a method for determining the rapid air leakage of a tyre. The method comprises the following steps: 1, detecting the pressure of the tyre each 6s; 2, executing step 3 if one detected pressure value is above 0.30bar lower than a last detected pressure vale, and returning to step 1 if not; 3, detecting the pressure of the tyre at the seventh second, and determining whether the obtained seventh-second pressure value of the tyre is equal to or greater than 0.04bar lower than the sixth-second pressure value, executing step 4 if the seventh-second pressure value is equal to or greater than 0.04bar lower than the sixth-second pressure value, and returning to the step 1 if not; and 4, detecting the eight-second pressure of the tyre, determining whether the obtained eighth-second pressure value of the tyre is equal to or greater than 0.04bar lower than the seventh-second pressure value, timely alarming if the eighth-second pressure value of the tyre is equal to or greater than 0.04bar lower than the seventh-second pressure value, and returning to the step 1 if not, wherein a case that the eighth-second pressure value of the tyre is equal to or greater than 0.04bar lower than the seventh-second pressure value shows that the air leakage of the tyre is fast carried out. The method of the invention can improve the detection of the rapid air leakage of the tyre and the alarming speed of a tyre pressure monitoring system.
Description
Technical field
The present invention relates to the tire inflation pressure determining system of vehicle electric field, particularly relate to a kind of tire determination methods of gas leakage fast.
Background technology
Automobile is the modern vehicle, has become the essential vehicle of people's daily life.Along with the development of automobile industry, people are also increasingly high for the attention of safety, and TPMS (tire pressure monitoring system) is exactly the product of this safe revolution, and the means that a lot of countries have passed through law are with the standard fitting of TPMS as automobile.
Because tire is the important component part of automobile chassis, is not only carrying the all-mass of automobile, also will advance to automobile provides propulsive force, and plays the effect that relaxes ground shock.TPMS can monitor tire in real time, reminds chaufeur to note the potential safety hazard that possibly occur, and plays to shift to an earlier date trouble-saving effect.
At present, the GB draft points out, TPMS wants and can detect tire flat within 1 minute, carry out leakage alarm in gas leakage, and reminds chaufeur.If but gas leakage speed is very fast, it is breakneck in the so long time, just detecting gas leakage so.
Summary of the invention
The technical matters that the present invention will solve provides a kind of tire determination methods of gas leakage fast, can improve detection and alarm velocity that tire pressure monitoring system leaks gas for tire fast.
For solving the problems of the technologies described above, tire of the present invention is the determination methods of gas leakage fast, comprises the steps:
Step 1, every force value that detects a tire at a distance from 6 seconds;
If certain force value that once detects of step 2 surpasses 0.30bar than last the minimizing, then execution in step three, otherwise return step 1;
Step 4, detect once the force value of this tire again in the 8th second; Whether the force value of this tire that judgement is detected is compared the force value that detects for the 7th second and is reduced more than or equal to 0.04bar; If represent that then tire with very fast speed gas leakage, needs in time to report to the police; Otherwise return step
Adopt method of the present invention;, can detect timely rapidly faster under the situation at the tire flat speed ratio of vehicle, improve tire pressure monitoring system for the tire detection and the alarm velocity of gas leakage fast; Shorten time of fire alarming, make the problem that chaufeur can discovery tire more early exists.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is the scheme of installation of sensor;
Fig. 2 is the scheme drawing that receives telltale;
Fig. 3 is method testing process figure of the present invention.
The specific embodiment
Tire pressure monitoring system mainly is made up of two parts, and referring to Fig. 1, first is a sensor 1, and it is contained in the inside of tire 2, is fixed on the wheel hub through tire tube valve, can monitor the temperature of tire 2 in real time, pressure, acceleration/accel situation.Shown in Figure 2 in combination, second portion is installed in the position (what have is directly shown by instrument) of the easy observation of chaufeur in the driving compartment for receiving telltale 3, can show current tire pressure, and temperature and failure condition let chaufeur understand the situation of tire.Sensor 1 and to receive between the telltale 3 be that wireless signal through high frequency carries out the signal transmission.
The sensor 1 that is installed in tire 2 the insides can constantly be measured the pressure and temperature of tire, can judge through analyzing whether tire leaks gas; If find tire 2 gas leakage then the wireless signal of result through high frequency sent to receive telltale 3 fast, receive telltale 3 and remind chaufeur to note tire fault through the mode (leakage alarm sign 7 as shown in Figure 2) of sound and light alarm.
As shown in Figure 2, receive telltale 3 and be provided with acknowledgement key 4, temperature, pressure switch key 5 and tire switch key 6.
In conjunction with shown in Figure 3, in one embodiment of this invention, tire is the determination methods of gas leakage fast, comprises the steps:
Step 1, every force value that detected a tire at a distance from 6 seconds.
If certain detected value once of step 2 surpasses 0.30bar than last the minimizing, then execution in step 3, otherwise withdraw from judgement, detect at next 6 seconds (promptly restarting from step 1) again.
Step 4: the force value that detects once this tire in the 8th second again; Whether the force value of this tire that judgement is detected compares the 7th second detected value minimizing more than or equal to 0.04bar; If represent that then tire with very fast speed gas leakage, needs in time to report to the police.Otherwise withdraw from judgement, detected at next 6 seconds again (the 14th second).
More than through the specific embodiment the present invention has been carried out detailed explanation, but these are not to be construed as limiting the invention.Under the situation that does not break away from the principle of the invention, those skilled in the art also can make many distortion and improvement, and these also should be regarded as protection scope of the present invention.
