Abstract
A sensor device comprises a resolver 2 comprising a rotor provided on a rotation-side raceway member 4 of a hub unit 1 and a stator 7 provided on a stationary-side raceway member 3 of the unit 1, and a processing circuit for processing a signal to be output in accordance with an air gap between the stator 7 and the rotor 8. The processing circuit has a wheel ground contact load calculating unit for determining the ground contact load on a wheel from the air gap between the stator 7 and the rotor 8.
