It is very frustrating when a malfunction indicator light is illuminated on the dashboard. Reds are a big trouble, they are unlucky or may not be able to drive any more, but the orange lights should not be ignored either. Here is something that can light up on the dashboard after a simple tire change or just a simple pressure check. But what about the fuck?

For new cars put on the market since November 2014, the Union has made it mandatory to have a tire pressure monitoring system (TPMS). The idea is basically a good one, as despite the fact that traffic signs require you to check the condition of your tires before you leave, almost no one does it; they would probably be bled immediately after a wheel or light bulb change, and even a few people would normally sweat just after refueling. Among other things, the tire pressure monitoring system was invented and made mandatory.

When operating properly, the TPMS should indicate extreme loss of air - a pressure drop of 20 percent or more in 10 minutes - and inform the driver of the steady decrease in tire pressure for 60 minutes. From 40 km / h to the top speed of the car, the system must be functional.

There are two ways to find out if your tires are inflating properly. The first is the indirect method, it's simpler, cheaper, more trouble-free, for anyone who has one and is afraid of things going wrong anyway. It does not require any extra tools, just software to find out from the ABS sensor data if there is a tire on the car that has the wrong tire pressure.

The simplicity of the method is brilliant: the flatter wheel has a circumference other than that of the right pressure, so the speed of rotation of the defective, impeller will be different from the rest, which is quickly detected by the ABS. The disadvantage is that this method does not tell you which wheel is wrong and only works on the fly.

What was it used for first?

TPMS was first used by Porsche in 1986, and first appeared on a mass-production vehicle in 1999 on board a Peugeot 607. Technology is important not only for safety, but also for cost savings: when the pressure is low, the tire wears more, overheats, and the car consumes more due to higher rolling resistance. 10% lower pressure can reduce your mileage by about 10%, but when the pressure is too high, tire life is reduced, as well as vehicle stability and traction, and the chassis is used more quickly.
