ABSTRACT:
A hybrid vehicular power system and method in which an automotive vehicle having a conventional engine, an energy storing flywheel and an I.V. transmission, is propelled by coupling the flywheel for rotation with the input of the I.V. transmission in which, for a given input speed, the output of which may be varied from 0 or near 0 continuously to the input speed. The flywheel and the input of the I.V. transmission are coupled to the engine by an overrunning clutch so that the flywheel and the input will be driven at the same or higher speeds than the engine shaft. During initial operation of the vehicle, the engine is coupled to the input of the I.V. transmission and the output of the transmission coupled to the drive wheels of the vehicle. Engine speed and I.V. transmission speed ratio are varied to accelerate the vehicle from a stop. When the I.V. transmission ratio is adjusted to unity, a second mode of operation is initiated in which the engine drive shaft is connected directly with the drivewheel shaft and also with the output of the I.V. transmission. In this second mode of operation, excess power developed as a result of operating the engine at optimum efficiency is fed back through the I.V. transmission from the output to the input thereof. Continued storage of excess power may occur with flywheel speeds increased by the speed ratio of the I.V. transmission.
