Title:
TYPE RECOGNITION DEVICE FOR AUTOMOBILE TIRES
Document Type and Number:
WIPO Patent Application WO/2015/076199
Kind Code:
A1
Abstract:
Provided is a type recognition device for automobile tires, capable of detecting information about tire type, during travel, and not requiring a special sensor. The tire type recognition device comprises: a rotation sensor (2) that detects rotation signals from a wheel (1) so as to measure the speed of the automobile; a signal processing unit (3) that extracts fluctuation in rotation speed synchronized to rotation, from the rotation signals detected by this rotation sensor (2), and obtains a rotation speed fluctuation pattern synchronized to the rotation, from the extracted rotation speed fluctuation; a reference pattern storage unit (13) having stored therein either pattern data for rotation speed fluctuation patterns, for each of the plurality of tire (1a) types, or feature parameters related to the tire types; and a tire type determination unit (4) that compares the obtained rotation speed fluctuation pattern to a rotation speed fluctuation pattern recorded in the reference pattern storage unit (13) and estimates the tire (1a) type.
