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 operating speed range for the flywheel. Desirably, this speed range is as low as possible so as to minimize spin losses. 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 through the continuously variable ratio transmission (CVT) to the vehicle driving wheels.
