Present embodiments provide a kind of automobile, comprise device for monitoring tyre pressure as above.
Embodiment four
In prior art, each of device for monitoring tyre pressure takes turns the fixing tire location of the pressure sensor correspondence of tyre cavity, before automobile dispatches from the factory, producer can define tire location corresponding to each sensor, the corresponding Automobile Right front-wheel of such as A sensor, the corresponding Automobile Right trailing wheel of B sensor, the corresponding automobile the near front wheel of C sensor, the corresponding automobile left rear wheel of D sensor.But the position of tire can change sometimes, such as drive wheel pricks tire, can this tire of making amends for one's faults be changed on non-driving wheel after tire patching, after also such as vehicle often travels several ten thousand kilometers, each tire is needed to exchange upper/lower positions, to ensure that each wear on tyres is comparatively average, in this case, will there is mistake in the monitoring data of device for monitoring tyre pressure.
In order to address this problem, the device for monitoring tyre pressure in the present embodiment, does not need the tire that pre-defined pressure sensor is corresponding, and when tire location changes, device for monitoring tyre pressure adjusts shown tire location automatically.
Device for monitoring tyre pressure in the present embodiment comprises the pressure sensor being installed on inside tires, and barometric information is also sent on receptor by pressure sensor measuring pulley air pressure; Be installed on the receptor in operator's compartment and telltale, receptor receives the barometric information of pressure sensor, and barometric information shows by telltale; To be installed on tire, with pressure sensor wheel speed sensors one to one, the wheel speed sensors monitoring tyre rotation number of turns, that is to say monitoring tire running distance; Be arranged on the rotary angle transmitter on vehicle steering, the rotational angle of rotary angle transmitter monitoring direction dish.
In tire pressure monitoring process, when steering wheel angle is greater than predetermined angle, write down rotating of steering wheel direction (left and right, also may be defined as+or-, 0 or 1 etc.), by wheel speed sensors record four tyre rotation number of turns, be multiplied by the girth i.e. operating range of four tires of tire.By the contrast to four tire running distances, the rotational angle of bonding position dish judges four tire present positions, sets up the barometric information of pressure sensor and the corresponding relation of tire location, and by corresponding relation display over the display.
In such scheme, emphasis is by the contrast to four tire running distances, and the rotational angle of bonding position dish judges four tire present positions.As shown in Figure 1, advance to position B from position A when automobile is turned right, Figure 2 shows that the operating range of four tires in right-hand rotation process, can find out that the operating range of four tires is not identical; The length of the line of four shown in Fig. 3 lower right corner is identical respectively with the operating range of four tires, article four, line is respectively the operating range of right rear fire, right front fire, left rear tire, left front tire from top to bottom, can find out, the operating range of the operating range < left front tire of the operating range < left rear tire of the operating range < right front fire of right rear fire.The driving trace schematic diagram of left front tire and right front fire when Fig. 4 is automobile right-hand rotation; The driving trace schematic diagram of left rear tire and right rear fire when Fig. 5 is automobile right-hand rotation; The driving trace schematic diagram of right rear fire when Fig. 6 is automobile right-hand rotation; The driving trace schematic diagram of right front fire when Fig. 7 is automobile right-hand rotation; The driving trace schematic diagram of left rear tire when Fig. 8 is automobile right-hand rotation; The driving trace schematic diagram of left front tire when Fig. 9 is automobile right-hand rotation.
Particularly, in certain turning process, 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 judge
| 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 judges four tire present positions.
It should be noted that and automatically not reset when pressure of tire mal.Reason is that (such as normal value is set as 2.2bar-3.0bar when certain (or multiple) pressure of tire mal, then outside this numerical value is mal air pressure), the radius of tire differs comparatively large with principal radii, the distance travelled during tire rolling does not conform to theoretical.
When automobile turns left and turns right in addition, tire motoring condition is contrary, the rotational angle of bearing circle when therefore record turns left and turns right respectively.Moreover when tyre slip, the device for monitoring tyre pressure of the present embodiment does not work.
The present embodiment is provided with pressure sensor in each inside tires of automobile, the barometric information of acquisition is also sent to central processing module by the air pressure of pressure sensor monitoring place tire, central processing module determines the position of tire residing for each pressure sensor, set up the corresponding relation between barometric information and tire location, telltale shows described corresponding relation.By technical scheme of the present invention, do not need to define tire location corresponding to each sensor, even if the tire location of automobile changes, can ensure the correctness of monitoring data yet.
Many functional components described in this specification sheets are all called as module, specifically to emphasize the independence of its implementation.
