ABSTRACT:
A continuously variable, regenerative transmission is disclosed in which a continuously variable transmission assembly is employed in conjunction with a regenerative gear assembly incorporating high and low clutches and situated intermediate a prime mover, such as a vehicle engine, and an output, such as the drive train to vehicle wheels. By monitoring certain system conditions (such as the rate and direction of rotation desired for the output, the rate of rotation of the engine and belt slip) while simultaneously controlling the engine speed, a control subsystem adjusts the effective diameters of input and output pulleys of the continuously variable transmission assembly to obtain a pulley torque versus belt tension that gives a belt slip value which results in rotation of the output in the desired direction at a rate according to a predetermined ratio schedule of the rate of rotation of the engine with respect to the rate of rotation of the output under the measured instantaneous conditions and in view of the output speed desired.
