Abstract:
1. An apparatus for detecting an internal mechanical failure of a tire that is attached to a wheel of a vehicle while the vehicle is traveling, including: an information acquiring part for acquiring tire information on a predetermined portion of the tire at least in a tire radical direction and a tire width direction orthogonal to the tire radial direction during rotating while the vehicle is traveling, respectively; a deriving part for deriving a deformation amount of a contact-portion of the tire at least in the tire width direction based on the tire information, the contact-portion being in contact with the ground; a calculating part for calculating an evaluation value for determining a presence or absence of the internal mechanical failure based on the derived deformation amount of the tire at least in the tire width direction by the deriving part; and a determining part for comparing the calculated evaluation value by the calculating part with a predetermined reference value to determine whether or not the internal mechanical failure has occurred in the tire.
