Abstract
An autonomous, plug-in and sacrificial wear sensing system including at least one wearable sensor, autonomous energy supply and means for remote radio-frequency communication. The system includes a tubular tread wear indicator body embedded within a tire tread element. The indicator body is centered within the tread element and is shaped in the form of a tube. The sensor element operably changes in at least one electromagnetically measurable physical parameter as the tread element wears radially inward. The system provides a full tread wear system including the algorithm for signal and data processing, buffering and decision making routines to remotely provide vehicle driver or owner with current tire wear status, tire type—vehicle—season match and with real-time estimation of remaining tire life.
