Abstract
A vehicle wheel assembly comprises: a wheel for mounting a tire thereon; and an in-wheel motor mounted in the inner space of the wheel and comprising: a rotor connected to the wheel, wherein a magnet is mounted to a center portion of the rotor rotatably coupled with a bearing assembly and arranged at a rotation axis of the wheel, a stator configured to drive the rotor, a rotary sensor disposed in sensing relationship with the magnet mounted to the center portion of the rotor, the rotary sensor configured to be responsive to rotation of the magnet for generating a signal, and an electronic device comprising a circuit board and electronics; and a brake actuator configured to apply brake to the wheel or the rotor. The electronics mounted on the circuit board comprise a single electronic control unit configured to control both the in-wheel motor and the brake actuator.
