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.

Abstract: A motor control system shorts motor windings of a motor by using enhancement metal-oxide-semiconductor field-effect transistors (MOSFETs) so that the motor generates braking torque when all or some electric control units of the motor are disabled or failed. The motor control system comprises: a motor comprising a plurality of motor phase terminals; a plurality of electric control units electrically connected to the motor and configured to control the motor, wherein the electric control units configured to output control signals, respectively; a plurality of power sources, each of the power sources electrically connected to a respective one of the electric control units; and a shorting circuit connected between the power sources and the motor, the shorting circuit configured to selectively short the motor phase terminals in response to one or more of the control signals of the electric control units.
