Claim:
1. A vehicle state detection device for a vehicle comprising: a motor for the vehicle, wherein the vehicle has wheels; a rotational angle sensor associated with one of the wheels of the vehicle, the rotational angle sensor including: an electronic control unit, connected with the rotational angle sensor, and programmed to detect a variation in the magnetism detection signal output from the magnetism detection signal output part, which is generated by a change of a relative position between the rotor and the stator of the rotational angle sensor toward a direction other than a rotational direction of the rotor, and acquire a magnitude of the variation as an index of a magnitude of a force acting on the wheel associated with the rotational angle sensor from a road surface on which the vehicle is traveling.
