ABSTRACT:
An electrically variable transmission family providing low-content, low-cost electrically variable transmission mechanisms including first and second differential gear sets, a battery and three electric machines serving interchangeably as motors or generators. The three motor/generators are operable in a coordinated fashion to yield an EVT with a continuously variable range of speeds (including reverse).
