Abstract

The invention comprises an electro-mechanical continuously variable transmission (EMCVT) that uses a planetary gear system to provide a combination of electric and mechanical power for a vehicle or for stationary equipment. The EMCVT includes a clutch and brake system that allows power from a energy storage unit to be combined with the main power input (typically an engine) to provide a torque output greater than that available from the main power input alone.
