Title:
タイヤに作用する力の推定方法
Document Type and Number:
Japanese Patent JP5876667
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of estimating a force to be applied on a tire while improving accuracy of estimating a longitudinal force, lateral force and vertical force, and to provide a pneumatic tire to be used therefor.SOLUTION: The estimation method uses: six or more first strain sensor 10A mounted on one side-wall part 3A on the same circumferential line at equal intervals and having a maximum gain line inclined at an angle θ1 of 30-60 degree ; and n second strain sensors 10B mounted on the other side-wall part 3B in a symmetric position facing the first strain sensor 10A across a tire equatorial plane, and having a gain maximum line inclined at the same angle θ2 as the angle θ1 of the first strain sensor 10A and in the same direction as the maximum gain line of the first strain sensor 10A. The strain sensors are used for estimating three components Fx, Fy and Fz of the force.
