摘要： A hybrid powertrain includes a torque provider, an automatic transmission without a torque converter, and a transfer case configured for providing four wheel drive low range. A controller receives a signal indicative of the transfer case being in low range and determines if brake pedal torque is indicative of a brake pedal being released and, if so, commands engagement of a launch clutch of the transmission up to maximum creep torque capacity at a predetermined maximum gradient. The controller determines when torque provider speed is synchronized with vehicle creep speed, and upon such determination, controls the launch clutch to fully engage to a lock up state to mimic behavior of engagement of a manual transmission gear when the hybrid powertrain is in low range to thereby substantially eliminate a time lag associated with automatic transmissions having a torque converter or a constantly slipping launch clutch.

摘要： A transmission includes input and output shafts, a hybrid module coupled to the input shaft and a gearbox coupled to the module and output shaft. The hybrid module includes a first electric motor under driven by a gearset; a second electric motor coupled to a module output, a disconnect clutch coupled to the gearset and selectively to the input shaft; and a launch clutch coupled to the disconnect clutch and selectively to the module output. The gearbox includes three gearsets and five torque transmitting devices operable to generate six forward speeds. One torque transmitting device is a clutch brake applied with a piston that reaches over a park gear, and one is a selectable one way clutch. Two of the torque transmitting devices are radially stacked rotating clutches. The transmission includes and/or facilitates an engine only mode, an electric only mode, a hybrid mode and a battery charging mode.
