Step 103：According to the difference between the air pressure inside of tire and the external pressure of tire, the current tire of tire is determined
Pressure.
The present inventor has found in the utility model research process is carried out, during the use of tire, inside tires
Commonly greater than the reading of tire pressure monitoring system, the tire pressure reading shown on the tire pressure monitoring system of the prior art thus is wheel for air pressure
Air pressure inside tire subtracts a fixed atmospheric pressure value (generally in the standard atmospheric pressure that height above sea level is 0),
In fact, automobile from level land open to high mountain when, outside tires air pressure can decline, using the prior art fail synthesis examine
Consider outside tires air pressure change, it is likely that appear in tire pressure monitoring system and send out and tire occurs before police instruction split, it will exist compared with
Big security risk, comparing and following analysis of the detailed analysis referring to table 1：
By taking the tire of some admittedly special model as an example, if the maximum tire pressure of tire mark is 44psi：
When at level land, if the external pressure of tire is 14.69psi, the air pressure of inside tires is 50.69psi, at this point,
Use difference of the tire pressure that the present embodiment tire pressure monitoring method measures for the inner and outer air pressure of tire, i.e. 36psi.
When automobile open to height above sea level be 1000m when, the external pressure of tire is reduced to 12.94psi, inside tires
Air pressure is still 50.69psi, at this point, difference of the tire pressure that the present embodiment tire pressure monitoring method measures for the inner and outer air pressure of tire is used,
That is 37.75psi；
When automobile is opened in height above sea level as 5000m, the external pressure of tire is 7.55psi, and the air pressure inside of tire is still
For 50.69psi, at this point, using difference of the tire pressure that the present embodiment tire pressure monitoring method measures for the inner and outer air pressure of tire, i.e.,
43.14psi；However, at this time if using prior art tire pressure monitoring system, the reading of tire pressure monitoring system is in tire at this time
Tire pressure reading remains as 36psi at this time for portion's air pressure and the difference of scheduled standard atmospheric pressure, i.e. prior art tire pressure monitoring system, can
Seeing tire pressure that the tire pressure monitoring system of the prior art read, there are relatively large deviations with practical tire pressure, it is likely that appears in tire pressure prison
Generation tire is split before examining system sends out police instruction, it will there are larger security risks.And use the present embodiment technical solution
Tire pressure monitoring technology can more characterize the current practical tire pressure of tire, and detection is more preferably safe and reliable.
Table 1
To sum up, the tire pressure monitoring method of the utility model consider the air pressure of inside tires and due to height above sea level not
With or temperature difference caused by outside tires air pressure change, according to the external pressure of the air pressure inside of tire and tire it
Between the tire pressure that determines of difference, can more preferably characterize the current practical tire pressure of tire, therefore apply the present embodiment technical solution more
Add safe and reliable.
Embodiments described above does not form the limit to the technical solution protection domain.It is any in above-mentioned embodiment party
Modifications, equivalent substitutions and improvements made within the spirit and principle of formula etc., should be included in the protection domain of the technical solution
