ABSTRACT:
A high-efficiency vehicular transmission is provided. The transmission includes a transmission housing, a set of torque delivery elements which include first and second elements supported for rotation within the housing and an electric motor for changing angular velocity of at least one of the elements in response to an electrical signal during a shift to obtain a desired transmission ratio. At least one non-friction controllable coupling assembly has a coupling state for coupling the first element to either the second element or the housing and an uncoupling state for uncoupling the first element from either the second element or the housing, respectively. The at least one coupling assembly is non-hydraulically controlled to change state to maintain the desired transmission ratio.
