Abstract:
An apparatus for identifying tires comprising:a rotational speed detecting means for periodically detecting rotational speeds of tires of four wheels of a vehicle; a first calculating means for calculating a vehicle speed based on a measured value obtained by the rotational speed detecting means; a second calculating means for calculating acceleration/deceleration of the vehicle; a third calculating means for calculating a slip ratio from the rotational speeds of the four wheels; a fourth calculating means for respectively obtaining moving averages of the acceleration/deceleration and the slip ratios of the vehicle; a fifth calculating means for obtaining linear regression coefficients and correlation coefficients of the moving-averaged acceleration/deceleration of the vehicle and the slip ratio; a sixth calculating means for calculating a tire identifying coefficient based on the linear regression coefficients of which correlation coefficients of are not less than a specified value; and a tire identifying means for identifying tires which is presently mounted based on the tire identifying coefficient.
