Wheel-Speed Based Pressure Sensing
The direct pressure sensing approach described above requires new hardware - the pressure sensors, receiving antennas, and display. So why not instead use sensors already in the majority of new cars - the wheel-speed sensors used in traction control and ABS applications? By using the wheel speed sensors to detect tyre-to-tyre differences in straight-line wheel speeds, an under-inflated wheel can be identified. This is because the rolling radius of the wheel will decrease with a drop in pressure, and so relative to the other wheels, it will rotate more quickly.

However, while an elegantly simply approach, it does have some major downsides. The wheel-speed based pressure sensing approach is used in the 2001 BMW M3 convertible and 750iL models. In the M3 owner's manual the following warnings are made:
The system cannot alert you to severe and sudden tyre damage caused by external factors.
The system will not identify the natural, even loss of pressure in all four tyres.
Under certain circumstances, there may be false warnings or a delayed detection of losses in pressure when driving on snow-covered or slippery road surfaces.
A sporty driving style (slip at the wheels receiving the torque, high lateral acceleration) can lead to delayed system warnings.

Pas naujus XXXXXXXX automobilius stovi davikliai ratlankiuose (daviklis su ventiliu). Prie ratu, arkose stovi siustuvai/imtuvai, kurie siuncia signala davikliui ir is jo gauna atsakyma, kokis yra slegis. Dazniausiai saibom pareina davikliai, laidu jungtys. Patys siustuvai sugenda laaabai retai.

O sistema, skaiciuojanti rato pakitimus nuo ABS sistemos, kazkokia nesamone man gaunasi. Visu pirma turi buti ziauriai tikslus griacio skaiciavimas. Po kablelio min. 3-4 skaiciai. Turi buti vairo padeties davikliai, apkrovu davikliai r pan, kad sistema neapsigautu ilguose posukiuose, uzkrovus tik viena automobilio puse.

OT: jau matau perpektyva pacukams - sukinėti tokius ventylius lauk

Pacukai butu nesusiprate, o tu padejai suprasti :lol: Sakyciau reikia salinti sia minti, kol nepamate tas kam negalima :)

Tos ventilius su davikliais kad issukti,reikia padangas numontuoti.

Tikrai taip. Neismontavus padangos tu davikliu neimanoma isimti. O is isores jie labai nesiskiria nuo standartiniu, siek tiek patiuninguoti. O ir isidejus ta davikli i savo masina, naudos bus panasiai tiek, kiek is ozio pieno. Nes dar reikes siustuvo/imtuvo, proco informacijai apdirbt ir displejaus informacijai pateikt.
