MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202514121130 A) filed by The Goodyear Tire & Rubber Company on December 03, 2025, for Tire Wear Estimation System Employing Frictional Energy.
Inventors include Labella, Mario; and Singh, Kanwar Bharat.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: A wear estimation system for a tire includes a processor in electronic communication with a CAN bus system of a vehicle. A processor is configured to receive a total frictional energy of the tire and divide the total frictional energy into a longitudinal frictional energy estimation and a lateral frictional energy estimation with a separator. The longitudinal frictional energy estimation is received in a longitudinal acceleration classifier, which determines at least one of a low, medium, and high longitudinal frictional energy estimate. The lateral frictional energy estimation is received in a lateral acceleration classifier, which determines at least one of a low, medium, and high lateral frictional energy estimate. An output notification is generated including the longitudinal and lateral frictional energy estimates, and at least one of an estimated wear rate of the tire and an estimated wear state of the tire are determined from the output notification.
