Abstract
The methods and apparatuses of the present invention provides for powering and maneuvering (forward, reverse and steering) systems for amphibious vehicle, marine vessel or ground vehicle operation and control. An improved propulsion system may incorporate the use of electric motors combined with impellers which use positive and negative magnetic torque applications and allows for new control strategies when used in water or on the ground. More precise control of the motoring and steering forces is provided which is suitable for use in a variety of amphibious, marine vessels or ground vehicle applications. Various types of electric drive motor/generators may be incorporated for use therein. Intelligent motion control systems may provide for improved vehicle control that can provide motive force and braking force in a precisely controlled manner that significantly improves performance and has faster control dynamics incorporating a fully integrated electrical braking and maneuvering system.
