PORTOROZ, Slovenia—For all its capabilities, RFID might just be a bridge on the road to true smart-tire technologies, according to Andreas Puerschel, key development engineer of original equipment development at Hankook.
Speaking at a technology workshop during a recent Hankook press event in Slovenia, Puerschel noted that there is a lack of standardization in the area of tire sensors.
"We have QR codes, data-matrix codes, RFID, etc. (with) a mixture of functionalities," he commented. "For sure, not all will survive because they are not giving enough value for the costs involved."
Among current sensor technologies, the Hankook expert described RFID tags as the most advanced, particularly as the devices can store data and allow freedom to rewrite information.
"But RFID itself cannot work 'smart'," said Puerschel. "It can store data, it can save data, you can rewrite it, but it cannot work as a (smart) sensor."
RFID could be "a kind of bridge" until smart sensors arrive on the market, but Puerschel added, "why, then, also have an RFID (tag)? The customer will not pay extra money for it."
Puerschel believes smart tire sensors are "the only end-solution, and will become mandatory as we continue toward autonomous driving. From that perspective, RFID is a stop-gap solution."
