How Software-Based Tire Pressure Monitoring Exceeds Sensors
When people think of tire pressure monitoring, they often picture small sensors mounted in each tire. But today’s most innovative solutions don’t rely on hardware at all. Welcome to the world of software-based tire pressure monitoring—specifically, Tire Pressure Indicator by NIRA Dynamics, where advanced algorithms are redefining the limits of what indirect TPMS can achieve.
What Is Indirect TPMS—and Why Is It Better?
Unlike traditional TPMS systems that use physical sensors inside each wheel (known as direct TPMS), indirect TPMS uses software to analyze data from the vehicle’s existing systems—primarily wheel speed sensors. TPI by NIRA takes this concept to the next level with dual-detection algorithms that include spectrum analysis and machine learning techniques.
This allows the system to detect tire pressure loss with high accuracy, whether it’s a slow leak in a single tire or a rare event where all four tires deflate at the same rate. The result? Real-time pressure monitoring without any added hardware.
Proven Performance in Over 110 Million Vehicles
iTPMS is a proven technology. With over 110 million vehicles on the road already equipped with NIRAs iTPMS , it meets or exceeds global regulations like FMVSS 138 (USA), ECE R141 (Europe), and GB26149-2017 (China).
The software has been tested across all conditions—extreme temperatures, various road surfaces, and different vehicle load states—making it a reliable choice for automakers worldwide.
Software Solves What Hardware Can’t
Some may remember early concerns about indirect TPMS. But it’s important to know that these early issues were solved through software updates, no physical part replacements required. That’s a key advantage of software-based systems: they are easily updated, improved, and future-proofed.
Since its first release in 2007, T ire Pressure Indicator has evolved through multiple generations, each version fine-tuned for greater accuracy and resilience. And unlike sensor-based TPMS, there’s no risk of battery failure, sensor corrosion, or radio frequency interference.
Ready for the Software-Defined Vehicle Era
As the automotive industry transitions toward software-defined vehicles, having a TPMS solution that is sensor-free, cloud-ready, and fully AUTOSAR-compliant becomes a strategic advantage. In a world where sustainability, cost-efficiency, and digital integration matter more than ever, software-based TPMS isn’t just an alternative, it’s the future.
