<p>A sensor device comprises a resolver (2) constructed from a rotor (8) provided at a rotation-side raceway member (4) of a hub unit (1) and a stator (7) provided at a stationary-side raceway member (3) of the hub unit, and a processing circuit for processing a signal outputted in accordance with an air gap amount between the stator (7) and the rotor (8). The processing circuit has a portion for calculating a ground contact load on a wheel, and the portion calculates a ground contact load acting on the wheel from the air gap amount between the stator (7) and the rotor (8).</p> |
