Abstract
The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first and second differential gear sets, a battery, three electric machines serving interchangeably as motors or generators and up to three brakes. The three motor/generators are operable in a coordinated fashion to yield an EVT with a continuously variable range of speeds (including reverse). One of the brakes enables series hybrid operation.
