ABSTRACT:
In order to accurately and stably estimate the conditions of a running tire, a vehicle is equipped with a sensor-incorporating tire having, at an equal distance from the center in the axial direction of the tire, pressure sensors (11A,11B) buried in a tread rubber positioned on the outer side in the radial direction of the tire belt layer of a tire tread portion and on the inner sides in the radial direction of tread blocks, the contact length LAof the car body side and the contact length LBof the opposite side of the center in the axial direction of the tire are detected by using the duration times of pressure values from the pressure sensors (11A,11B) and a wheel speed from a wheel speed sensor (14), and the ratio R=LA/LBof the contact length LAto the contact length LBis computed to estimate lateral force generated by the tire, or the average contact length LABwhich is the average value of the contact lengths LAand LBis computed to determine a load applied to the tire.
