Tire state quantity estimating device, tire state quantity estimation method and tire state quantity estimation program

摘要

In the simple configuration, the cornering power is accurately estimated.Tire state estimation deviceTire powerThe friction coefficient between the tire and the road surface is obtained (11).Based on the generation of tire resistance and the tire bearing force derived from the acquired tire force and friction coefficientThe ground length of the tire in the non controlled driving condition, which is generated in the front and rear directions of the tire of the tire generating force, is estimated to be less than a predetermined threshold (10)Estimated tire ground length andBased on the generated tire powerThe cornering power of the tire is estimated (23).Diagram
