Claim 0:
1. A tire force estimator comprising:
a measuring unit configured to measure accelerations for a four-wheeled vehicle including four wheels, a vehicle body, and a suspension structure that connects at least one wheel of the four wheels to the vehicle body, the suspension structure including a shock absorber that mitigates shock applied to the at least one wheel, the accelerations including an acceleration of the vehicle body in a horizontal direction and an acceleration of the at least one wheel in a vertical direction, the measuring unit being further configured to measure a stroke amount of the shock absorber; and
a processing unit configured to estimate a tire force acting on the at least one wheel from a ground surface in the vertical direction based on the acceleration of the vehicle body in the horizontal direction, the acceleration of the at least one wheel in the vertical direction, and the stroke amount.
