Abstract: A scalable tractive power system for vehicles (car, truck, bus, semi-trailer), integrated with all-wheel steering system which leverage synergies between plurality of differently designed electric traction-motors and all-wheel electric steering-motors is configured with plurality of sensors to virtually eliminate wheel-dragging and EPS, as part of virtually 100% dynamic efficiency. A fully automated electronic clutch-system attached to selected electric traction motors is configured to carry out above 90% traction efficiency by coupling to wheels selected electric traction-motors in their high efficiency range of operation, and de-coupling and replacing electric traction-motors with another electric traction-motors while the vehicle is changing speed or when the vehicle requires higher or lower tractive-power, from forward-motion start to top-rated speed of the vehicle.

Abstract: A railway-vehicles scalable tractive power system, integrated into all-wheel steering and braking systems to leverage synergies between plurality of differently designed electric traction-motors, electric steering motors and electric brake calipers; configured with plurality of sensors to eliminate wheel-dragging at virtually 100% dynamic efficiency. A fully automated electronic clutch-system attached to selected electric traction motors configured to perform above 90% traction efficiency by coupling to wheels selected electric traction-motors in their high efficiency range of operation, or de-coupling and replacing electric traction-motors with another electric traction-motors while the vehicle is changing speed or when it requires higher or lower tractive-power, from forward-motion start to top-rated speed.

Abstract: A vehicle, integrated all-wheel propulsion and steering system with plurality of propulsion and steering power sources, designed with enumerate specifications are coupled to, and de-coupled from a final drive of the vehicle propulsion system. A controller receives input-signals from the driver steering-wheel sensor; computes a set of reactions to the plurality of steering-actuators, wherein feedback-mechanism with each wheel-position sensor, the controller secures each wheel in its computed angle. In different speed and load conditions, the controller is programmed to compute a desired power demand then couple to the final drive[s] the propulsion power source[s] that is designed to do-the-job with the least energy consumption. When the vehicle changes speed and load, the controller couples a different power source[s], and de-couples the previous power source[s] to meet the power demand.
