The world-leading tire
pressure monitoring system.
75% of failing tires are caused by underinflation or slow leakage, and tire problems are the third most common reason for passenger vehicle breakdowns. With every 0.2 bar the tire is underinflated, fuel consumption increases 1.5% and the life span of a tire decreases 15%. Approximately 20% of all passenger cars have tires which are underinflated by up to 40%.
The solution to these problems? The world’s most advanced indirect tire pressure monitoring system: Tire Pressure Indicator, TPI by NIRA. With it, the driver is alerted if any of the tires is underinflated – long before the tire breaks down. This improves safety, of course, but that’s really only the beginning. As tire wear and fuel consumption are reduced when tires are correctly inflated, it also improves economy. And decreases the environmental impact.
TPI by NIRA is a software solution which determines the tire inflation pressure from the wheel speed signals. That means it does not require any in-wheel pressure sensors and RF components. Which, of course, makes it very cost-effective. Thanks to its AUTOSAR compliant interface, TPI can also be quickly and easily integrated with various systems running on different hardware. Moreover, it fulfills all current TPMS legislations worldwide, including ECE-R64 and FMVSS138.
TPI is capable of detecting pressure drops in one, two, three, or even up to all four tires,and it can also isolate which tires, exactly, are underinflated.The system is robust against surface changes, load variations and driving styles, and it automatically adjusts to different types of tires.
