Abstract
A wheel load estimation device that estimates wheel load acting on wheels of a vehicle includes an acquisition unit, a calculation unit, and an estimation unit. The acquisition unit acquires detection value output from a sensor as a parameter. The parameter is a parameter related to a motion of the vehicle. The calculation unit calculates an inertial force generated in the vehicle based on the parameter and a mass of the vehicle. The estimation unit estimates the wheel load based on the inertial force and a predetermined estimation equation.
