Abstract
An improved control system and method for controlling the operation of a flywheel type power delivery system, such as used in an automotive vehicle. A predetermined maximum vehicle speed limit dictates the working displacement of a variable displacement engine to match efficient engine output to the power requirements of the system. Above a threshold vehicle speed of approximately 45 miles per hour, the flywheel is completely uncoupled from the system and vehicle propulsion is provided by direct coupling of the engine (at maximum displacement) through the continuously variable ratio transmission (CVT) to the vehicle driving wheels.
