Polyn advances tire monitoring with vibration sensors

Hannover, Germany – UK semiconductor company Polyn Technology has introduced a new tire monitoring sensor which can process vibration data locally on the tires.

Introduced 20 March, VibroSense is a solution which uses ‘neuromorphic analog signal processing’ (NASP) technology to analyse tire vibration, said Polyn CEO Aleksandr Timofeev.

The process, according to Timofeev, involves “deep neural networks capable of confidently identifying vibration patterns.”

The solution, according to Polyn, can be applied to "many different types of tires in a variety of monitoring applications."

The in-tire vibration sensor data can help determine the road condition for better grip and control. 

The system can inform the car's advance driver assistance and other systems about surface conditions such as ice on the road or a pavement change.

It can also obtain tire wear data or indicate wheel imbalance issues, to avoid fuel inefficiency, explained Eugene Zetserov, VP marketing and business development.

The sensor, according to Polyn, has shown 95% accuracy in detecting road conditions.

As part of technology, Polyn said it had built “a facility” for tire data collection and is developing a "library of vibration data patterns".

Such data include information from various tire types, road surface conditions, pavements and levels of tire wear.

The company is also working with “several tire makers” on proofs of concept and with sensor node manufacturers, to incorporate VibroSense in "new-generation" tire monitoring systems, according to Zetserov.
