PROBLEM TO BE SOLVED: To provide a tire behavior estimation device capable of simply and highly accurately estimating a tire behavior.SOLUTION: A tire behavior estimation device 10 estimates a behavior of a tire of a vehicle, and obtains a vertical shift Susing a camber angle variation-rate dγof a lateral friction factor μof the tire, and obtains a horizontal shift Susing a camber stiffness CS, and includes an estimation part 13 for estimating a lateral force Fof the tire during natural slipping using the vertical shift Sand the horizontal shift S. According to the tire behavior estimation device 10, the vertical shift Sis obtained as a function of the camber angle variation-rate dγ, and the horizontal shift Sis obtained as the function of the camber stiffness CS, and thereby, an influence affecting the lateral force Fby a camber angle γ of the tire during the natural slipping can be simply and highly accurately estimated. |
