Present embodiments provide a kind of automobile, including device for monitoring tyre pressure as above.
Embodiment four
In prior art, each of device for monitoring tyre pressure takes turns the tire that the pressure transducer correspondence of tyre cavity is fixed
Position, before automobile dispatches from the factory, producer can define the tire location that each sensor is corresponding, such as A sensor
Corresponding Automobile Right front-wheel, B sensor correspondence Automobile Right trailing wheel, C sensor correspondence automobile the near front wheel, D passes
Sensor correspondence automobile left rear wheel.But the position of tire can change sometimes, such as driving wheel pricks tire,
The tire this can made amends for one's faults after tire patching is changed on non-driving wheel, after the most such as vehicle often travels several ten thousand kilometers,
Need each tire exchanges lower position, to ensure that each tire wear is relatively average, in this case, tire pressure
The Monitoring Data of monitoring device will appear from mistake.
In order to solve this problem, the device for monitoring tyre pressure in the present embodiment, it is not necessary to pre-defined pressure passes
The tire that sensor is corresponding, when tire location changes, device for monitoring tyre pressure adjusts shown wheel automatically
Fetal position.
Device for monitoring tyre pressure in the present embodiment includes the pressure transducer being installed on inside tires, pressure sensing
Device is measured tire pressure and is sent on receptor by barometric information；The receptor that is installed in driver's cabin and aobvious
Showing device, receptor receives the barometric information of pressure transducer, and barometric information is shown by display；Install
On tire and pressure transducer wheel speed sensors one to one, wheel speed sensors monitoring tyre revolution moving-coil
Number, that is to say monitoring tire running distance；The rotary angle transmitter being arranged on vehicle steering, rotation angular sensing
The rotational angle of device monitoring direction dish.
During tire pressure monitoring, when steering wheel angle is more than predetermined angle, write down steering wheel rotation direction
(left and right, it is possible to be defined as+or-, 0 or 1 etc.), by four tyre rotation of wheel speed sensors record
The number of turns, is multiplied by the operating range of girth that is four tire of tire.Right by four tire running distances
Ratio, the rotational angle of bonding position dish judges four tire present positions, it is established that the gas of pressure transducer
Pressure data and the corresponding relation of tire location, and corresponding relation is shown over the display.
In such scheme, it is important that by the contrast to four tire running distances, the rotation of bonding position dish
Angle judges four tire present positions.Put in place as it is shown in figure 1, advance from position A when automobile is turned right
Put B, Fig. 2 and show four tires operating range during turning right, it can be seen that the row of four tires
Sail distance to be different from；The operating range of the length of four shown in Fig. 3 lower right corner bar line and four tires is respectively
Identical, four lines are from top to bottom respectively right rear fire, right front fire, left rear tire, the row of left front tire
Sail distance, it can be seen that < operating range of right front fire be < left rear tire for the operating range of right rear fire
Operating range < the operating range of left front tire.Left front tire and the row of right front fire when Fig. 4 is automobile right-hand rotation
Sail track schematic diagram；Left rear tire and the driving trace schematic diagram of right rear fire when Fig. 5 is automobile right-hand rotation；Figure
The driving trace schematic diagram of 6 right rear fires when turning right for automobile；The row of right front fire when Fig. 7 is automobile right-hand rotation
Sail track schematic diagram；The driving trace schematic diagram of left rear tire when Fig. 8 is automobile right-hand rotation；Fig. 9 is Automobile Right
The driving trace schematic diagram of left front tire when turning.
Specifically, during certain is turned, wheel speed sensors detects:
| Wheel speed sensors 1 | Wheel speed sensors 2 | Wheel speed sensors 3 | Wheel speed sensors 4 | |
| Operating range | 471.59 rice | 544.34 rice | 628.67 rice | 685.09 rice |
Then can be determined that
| Wheel speed sensors 1 | Wheel speed sensors 2 | Wheel speed sensors 3 | Wheel speed sensors 4 | |
| Operating range | 471.59 rice | 544.34 rice | 628.67 rice | 685.09 rice |
| Judge | Right rear fire | Right front fire | Left rear tire | Left front tire |
Thus realize by the contrast to four tire running distances, the rotational angle of bonding position dish is judged
Four tire present positions.
It should be noted that and the most automatically reset when pressure of tire is abnormal.Reason be when certain (or
Multiple) pressure of tire abnormal time (such as normal value is set as 2.2bar-3.0bar, then outside this numerical value
For abnormal air pressure), the radius of tire differs relatively big with principal radii, the distance travelled during tire rolling with
Theoretical does not corresponds.
When additionally automobile turns left and turns right, tire transport condition is contrary, and record turns left and the time side that turns right the most respectively
To the rotational angle of dish.Furthermore, when tyre slip, the device for monitoring tyre pressure of the present embodiment does not works.
The present embodiment is provided with pressure transducer in each inside tires of automobile, and pressure sensor monitoring place is taken turns
The barometric information of acquisition is also sent to central processing module by the air pressure of tire, and central processing module determines each pressure
The position of tire residing for force transducer, sets up the corresponding relation between barometric information and tire location, display
Show described corresponding relation.Pass through the technical solution of the utility model, it is not necessary to define each sensor corresponding
Tire location, even if automobile tire location change, also can guarantee that the correctness of Monitoring Data.
These many functional parts described in this description are all referred to as module, in order to specifically emphasize it
The independence of implementation.
The above is preferred implementation of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of without departing from principle described in the utility model, it is also possible to make some changing
Entering and retouch, these improvements and modifications also should be regarded as protection domain of the present utility model.
