POLYN Technology has successfully completed an official test of its VibroSense Tire Grip Monitoring Solution, which enables real-time awareness of road surface conditions.
POLYN tested the VibroSense neural network model on standard tires from one of the world’s leading manufacturers in a recent series of trials at the renowned Applus IDIADA multi-surface proving ground in Spain. The tests were conducted on various surfaces, including dry and wet asphalt, dry and wet concrete pavement, wet basalt to simulate snow, and wet ceramic to simulate ice.
The solution is powered by a NASP (neuromorphic analog signal processing) ultra-low-power chip with an integrated MEMS accelerometer. With that, it can estimate the PFC, the peak friction coefficient, to provide real-time information about tire grip, enhancing control and safety in vehicles of all types.
The IDIADA facility testing was the first in a series to be conducted with different tire manufacturers. POLYN is poised to demonstrate the value of its solution across the entire tire industry.
David Shaw, analyst with Tire Industry Research in the United Kingdom, observed the tire tests at IDIADA. He noted that while “in principle, measuring tire-road friction is not too difficult, the challenge is to do it on a practical system that costs just a dollar or two, consumes tiny amounts of energy, and needs only limited data bandwidth. None of the top tire makers could achieve that, but POLYN has.”
“VibroSense is the missing link between the tire and the road,” said Aleksandr Timofeev, CEO of POLYN. “It delivers a true sense of surface conditions through real-time tire-road physical interaction. It provides unprecedented insights into tire grip and behaviour, and vehicle dynamics, all without altering existing vehicle hardware.”
