Abstract

An estimation method of estimating wheel loads applied to a plurality of wheels (14, 24) of a vehicle (1, 1A), which includes: a sprung body (10) including a vehicle body (11) and a first wheel (14) of the wheels (14, 24); an unsprung body (20) including an axle (25) and a second wheel (24) of the wheels (14, 24); a support unit (40) for supporting the vehicle body (11) and the axle (25); an actuator (30) configured to restrict rotations of the vehicle body (11) and the axle (25) in a roll direction; and a sensor (50), includes: calculating calculated values (IFvc) based on acquired motion information (IFm) relating to motion of the vehicle (1, 1A) acquired by the sensor (50); and estimating the wheel loads of the wheels (14, 24) based on the calculated values (IFvc) and a predetermined estimation formula. The calculated values (IFvc) include accelerations at respective center-of-gravity positions of the sprung body (10) and the unsprung body (20), and roll stiffness distributions of the sprung body (10) and the unsprung body (20).
