Sectional Casings Patents (Class 152/343.1)
  • Patent number: 8849500
    Abstract: A system for predicting tire casing life remaining for a casing in a tire, the system including: a tire condition measurement unit that measures one characteristic value including tire internal pressure information indicating at least one of a tire condition and a vehicle running condition; a temperature history estimation unit that estimates a temperature history of at least one location in at least one casing structural member based on the characteristic value; a member physical property calculation unit that calculates at least one current physical property value of the at least one casing structural member that degrades due to tire internal air temperature based on at least the tire internal pressure information and the temperature history; and a remaining drivable distance prediction unit that predicts a drivable distance of the tire until the current physical property value reaches a physical property value limit set in advance.
