Abstract
An inductively powered toy vehicle and an associated track with inductive charging segment. The vehicle may include a secondary coil, a drive motor, an electrical power storage device connected between said secondary coil and said drive motor, and a wireless communications unit. The charging segment may include a primary coil, a sense circuit operable to detect the presence of the vehicle based on a change in the detected impedance of the primary coil, and a power control unit operable to provide a time-varying current to the primary coil when the vehicle traverses the charging segment. The primary coil is positioned within the race track adjacent the track upper surface. The vehicle drive motor may be operable at first and second speed settings, and a remote control device can provide operating instructions to the vehicle wireless communications unit.
