Embodiment
The embodiment of the disclosure is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explained the disclosure, is not limited to the disclosure.
Fig. 1 is the flow chart of the monitoring method of the abnormal tyre pressure provided according to a kind of embodiment of the disclosure.Such as Fig. 1 institutes
Show, this method may comprise steps of.
In a step 101, when vehicle is in and stablizes transport condition, respectively to by the first round on the first wheel
Pulse number caused by fast sensor and the pulse number as caused by the second wheel speed sensors on the second wheel
Added up, obtain the first accumulated value corresponding with the first wheel and the second accumulated value corresponding with the second wheel.Wherein, first
Wheel and the second wheel belong to same vehicle bridge.
When its straight line smooth-ride, and in the absence of phenomena such as example braking, turn, jolting, illustrate that vehicle is in stable
Transport condition.Wheel speed sensors are mounted on the wheel of vehicle at present, wheel speed sensors are fixed on knuckle bottom plate and kept
It is motionless.The gear ring of wheel is on wheel hub, and during the traveling of vehicle, gear ring rotates with wheel hub.Illustratively, the tooth of wheel
Circle may, for example, be gear ring of the gear ring of 80 teeth, the gear ring of 100 teeth, 120 teeth etc..During being rotated with wheel hub, gear ring
Gap between tooth top and the sensing head of wheel speed sensors changes, and wheel speed sensors produce induced voltage pulse letter therewith
Number.Illustratively, for each revolution, 100 pulse signals can be produced for the gear ring of 100 teeth, wheel.Believed according to caused pulse
Number can obtain the traveling number of turns such as wheel, wheel wheel speed.
When vehicle is in and stablizes transport condition, two wheels (the first wheel and the second car for belonging to same vehicle bridge
Wheel), due to the progressive rolling movement of wheel, can continue to produce pulse signal.Can be to by the first wheel speed on the first wheel
Pulse number caused by sensor and the pulse number as caused by the second wheel speed sensors on the second wheel enter
Row is cumulative, obtains the first accumulated value corresponding with the first wheel and the second accumulated value corresponding with the second wheel, by this first
Accumulated value and the second accumulated value could be aware that whether wheel tyre pressure exception occurs in vehicle travel process.
In a step 102, according to the first accumulated value and the second accumulated value, it is determined whether the wheel of abnormal tyre pressure be present.
In vehicle travel process, because the first wheel and the second wheel belong to same vehicle bridge, when wheel tyre pressure is normal,
The first accumulated value and the second accumulated value are sufficiently close in theory.If the tire pressure of a wheel in two wheels occurs different
Often, because the wheel of tire pressure deficiency slightly reduces compared to the normal wheel of tire pressure, its rolling radius, therefore reached in vehicle traveling
When to certain mileage and continuing traveling, the difference of first wheel and the rolling number of turns of the second wheel can be increasing.Accordingly,
Difference between the second accumulated value corresponding with the second wheel of first accumulated value corresponding to first wheel can be increasing.Pass through
The difference may determine whether the wheel of abnormal tyre pressure.
In one embodiment, preset when the difference between the first accumulated value and the second accumulated value is more than or equal to first
During threshold value, it is determined that the wheel of abnormal tyre pressure be present, and the wheel that abnormal tyre pressure be present includes the first accumulated value and the second accumulated value
In higher value corresponding to wheel.First predetermined threshold value can be the cumulative pulse number and the second wheel of the first wheel
The maximum impulse signal number of phase tolerace between cumulative pulse number.
Illustratively, when the first accumulated value is big more than the difference between the second accumulated value and the first accumulated value and the second accumulated value
When the first predetermined threshold value, illustrate that the turnning circle of the first wheel is more than the second wheel, the i.e. rolling of the first wheel half
Footpath is less than the rolling radius of the second wheel, illustrates that the tire pressure of the first wheel reduces, it may be determined that the car of abnormal tyre pressure be present
Wheel, and the wheel of abnormal tyre pressure includes the first wheel.
For another example when the second accumulated value is big more than the difference between the first accumulated value and the second accumulated value and the first accumulated value
When the first predetermined threshold value, illustrate that the turnning circle of the second wheel is more than the first wheel, the i.e. rolling of the second wheel half
Footpath is less than the rolling radius of the first wheel, illustrates that the tire pressure of the second wheel has reduced, it may be determined that abnormal tyre pressure be present
Wheel, and the wheel of abnormal tyre pressure includes the second wheel.
In another embodiment, when the difference percentage between the first accumulated value and the second accumulated value is more than or equal to
During the second predetermined threshold value, it is determined that the wheel of abnormal tyre pressure be present, and the wheel that abnormal tyre pressure be present includes the first accumulated value and the
The wheel corresponding to higher value in two accumulated values.Wherein, the difference percentage between first accumulated value and the second accumulated value
It is the percentage that difference between the first accumulated value and the second accumulated value accounts for higher value among the two.Illustratively, if the first wheel
Corresponding first accumulated value is 80000, and the second accumulated value corresponding to the second wheel is 70000, then the difference percentage can be with
Calculated by this equation：It can thus be concluded that the difference percentage is 12.5%.
Second predetermined threshold value can be that the cumulative pulse number of the first wheel allows phase with the pulse number that the second wheel adds up
The largest percentage of difference.
Illustratively, when the first accumulated value is more than the difference hundred between the second accumulated value and the first accumulated value and the second accumulated value
Divide than when being more than or equal to the second predetermined threshold value, it may be determined that the wheel of abnormal tyre pressure be present, and the wheel of abnormal tyre pressure be present
Including the first wheel.
For another example when the second accumulated value is more than the difference hundred between the first accumulated value and the second accumulated value and the first accumulated value
Divide than when being more than or equal to the second predetermined threshold value, it may be determined that the wheel of abnormal tyre pressure be present, and the wheel of abnormal tyre pressure be present
Including the second wheel.
Above two mode, using the similitude when vehicle travels of two wheels in same vehicle bridge, can directly it lead to
The difference crossed between the first accumulated value and the second accumulated value of two wheels determines whether there is the wheel of abnormal tyre pressure, simply
It is convenient.
In another embodiment, when any one of the first accumulated value and the second accumulated value are more than default standard
The value and difference between the standard value is when being more than or equal to three predetermined threshold values, it is determined that the wheel that abnormal tyre pressure be present includes
Wheel corresponding to this any one.Wherein, the 3rd predetermined threshold value can be accumulated value (in the first accumulated value and the second accumulated value
Any one) maximum difference of phase tolerace between default standard value.
Demarcation to sample car could be aware that the standard value when different pressures, different loads, and can be as
Criterion.Illustratively, the standard value can be the arteries and veins corresponding to the minimum tire pressure that wheel allows in the range of normal tire pressure
Rush signal number accumulated value.In vehicle travel process, when any one of the first accumulated value or the second accumulated value are more than the standard
Value and when the difference between the standard value reaches three predetermined threshold values, it may be determined that the wheel of abnormal tyre pressure be present, and this is deposited
Abnormal tyre pressure wheel for accumulated value (any one of the first accumulated value and the second accumulated value) between default standard value
Difference reach the wheel of the 3rd predetermined threshold value.Illustratively, if the first accumulated value is more than standard value and between the standard value
Difference reaches the 3rd predetermined threshold value, then can determine that the wheel that abnormal tyre pressure be present includes the first wheel.For another example if first is tired
It is value added to reach the 3rd predetermined threshold value more than default standard value and the difference between the standard value, and the second accumulated value is big
Reach the 3rd predetermined threshold value in the standard value and the difference between the standard value, then can determine the car that abnormal tyre pressure be present
Wheel includes the first wheel and the second wheel.
In another embodiment, when any one of the first accumulated value and the second accumulated value are more than default standard
The value and difference percentage between the standard value is when being more than or equal to four predetermined threshold values, it is determined that the car of abnormal tyre pressure be present
Wheel include this any one corresponding to wheel.Wherein, the difference percentage is greater than the accumulated value of default standard value (first is tired
Any one of value added and second accumulated value) difference between the standard value accounts for the accumulated value more than default standard value
Percentage.Illustratively, if default standard value is 80000, and the first accumulated value is more than the standard value, is 100000, then the
Difference percentage between one accumulated value and the standard value can be calculated by this equation： The difference percentage can be obtained as 20%.4th predetermined threshold value can be accumulated value with presetting
Standard value between phase tolerace largest percentage.
Illustratively, if the second accumulated value is more than default standard value and the difference percentage between the standard value reaches
4th predetermined threshold value, it may be determined that the wheel that abnormal tyre pressure be present includes the second wheel.
Above two mode, when vehicle is in and stablizes transport condition, by the first accumulated value and the second accumulated value and vehicle
The standard value contrast demarcated in advance, there is the situation of abnormal tyre pressure and the first accumulated value and the second accumulated value simultaneously in two wheels
Between difference it is unconspicuous in the case of, can also determine wheel tyre pressure exception, to the determination of the wheel of abnormal tyre pressure be present more
Add comprehensively.
In another embodiment, the mode that above-mentioned first accumulated value can be compared with the second accumulated value and above-mentioned
First accumulated value is combined with any one in the second accumulated value with the mode that default standard value compares, to reach more accurate
Really monitor the effect of abnormal tyre pressure.
, can be directly true by pulse number caused by wheel speed sensors in vehicle travel process by such scheme
Surely it whether there is the wheel of abnormal tyre pressure, realize the monitoring to wheel tyre pressure, save cost.
