Abstract
A drive system having eCVT functionality with AMT cost advantages includes a transmission having a plurality of different operating modes. The system includes a transmission output shaft, a stationary member and a gear set including first, second, and third elements. The first element connects with the transmission output shaft. An output shaft of a non-electric power plant connects with the first element through the second element for driving the first element. A drive shaft of an electric power plant connects with the first element through the third element for driving the first element. The system includes a plurality of non-friction, controllable, coupling assemblies. A first coupling assembly has a first coupling state for grounding the second element to the stationary member, a second coupling state for grounding the third element to the stationary member and an uncoupling state to allow the second and third elements to drive the first element.
