Abstract: A two motor electric drive hybrid transmission for a vehicle. The two motor electric drive hybrid transmission allows both electric motors to provide propulsive force during engine on and engine off operations when desired. The two motor electric drive hybrid transmission also provides improved and flexible operating configurations.

Abstract: A hybrid powertrain for a vehicle having a disconnect clutch located between an internal combustion engine, or other power source, and a hybrid transmission. When deactivated, the disconnect clutch decouples the engine from the hybrid transmission, which enables the hybrid transmission input shaft to rotate independently of the internal combustion engine. This enables enhanced electric drive performance for the hybrid transmission. The disconnect clutch provides for internal combustion engine starting, including internal combustion starting at high vehicle speeds.

Abstract: A method of operating a hybrid transmission includes controlling the transmission according to a drive mode, which includes a continuously variable speed relationship, and controlling the transmission according to a fixed speed relationship mode, which includes a plurality of fixed speed relationships including mechanical gear ratios and virtual gear ratios.

Abstract: A method of operating a hybrid transmission includes controlling the transmission according to a drive mode, which includes a continuously variable speed ratio, and according to automatic and manual fixed speed relationships modes, which include a plurality of fixed speed relationships including mechanics gear ratios and virtual gear relationships. The method also includes receiving a driver request for transmission operation in one of an Economy or a Sport mode, and operating the transmission in the requested Economy or Sport modes.

Abstract: An air-flow management system for controlling the supply air to a motor vehicle passenger compartment is disclosed. The air-flow management system includes a reversible heat pump system for transferring heat energy between an outside environment and a refrigerant. Air from the outside environment, fresh air, and from the passenger compartment, recirculated air, is forced through the air-flow structure by a blower resulting in the transfer of heat energy between the refrigerant and the passenger compartment. A recirculation door provides a means for controlling the mixture of fresh air to recirculated air that flows through the air-flow structure. The position of the recirculation door is selectable by a controller to prevent fogging during the transition from cooling mode to heating mode, minimize the energy expended conditioning the passenger compartment air, and prevent the backflow of unconditioned outside air from the fresh air duct into the recirculation duct.
