A battery control system for controlling a state of charge of a hybrid vehicle battery includes a detecting arrangement for determining a vehicle operating state or an intended vehicle operating state and a controller for setting a target state of charge level of the battery based on the vehicle operating state or the intended vehicle operating state. The controller is operable to set a target state of charge level at a first level during a mobile vehicle operating state and at a second level during a stationary vehicle operating state or in anticipation of the vehicle operating in the stationary vehicle operating state. The invention further includes a method for controlling a state of charge of a hybrid vehicle battery.

A powertrain system is provided that includes a first prime mover, a second prime mover and a transformer module. In an embodiment, the transformer module includes a planetary gearset having a first rotary element connected to the first prime mover, a second rotary element connected to the second prime mover, and a third rotary element comprising an output member of the transformer module. The powertrain system also includes a power shunt between the first prime mover and the second prime mover.

Hybrid powertrain system and transformer module

A powertrain system is provided that includes a prime mover and a change-gear transmission having an input, at least two gear ratios, and an output. The powertrain system also includes a power shunt configured to route power applied to the transmission by one of the input and the output to the other one of the input and the output. A transmission system and a method for facilitating shifting of a transmission system are also provided.

Hybrid powertrain system including smooth shifting automated transmission

A hybrid vehicle powertrain system includes a first prime mover, a first prime mover driven power transmission mechanism having a power take-off adapted to drive a vehicle accessory, and a second prime mover. The second prime mover is operable to drive the power transmission mechanism alone or in combination with the first prime mover to provide power to the power take-off through the power transmission mechanism. The invention further includes methods for operating a hybrid vehicle powertrain system.

The present invention discloses a method for controlling up-shifting of multiple speed change gear transmission used with a turbocharged internal combustion engine. One or more engine operating parameters are selected for control by the control unit. The control unit establishes that an up-shift is about to occur. The engine is placed in a transient operating mode. The transient operating mode includes the steps of reducing a magnitude of at least one of the engine speed and the engine torque to enable shifting from a first gear, and modulating the selected engine operating parameter to maintain the boost pressure by one of increasing the exhaust energy and maintaining the rotational speed of the turbocharger while the magnitude of the at least one of the engine speed and the engine torque is reduced. The control unit establishes that the shift from the first gear has been completed. Upon establishing that the shift from first gear has been completed, the engine is returned to the full-load condition while the selected engine parameter is immediately modulated so as to maintain or increase the torque output of the engine after the shift from the first gear, and the modulation of the selected engine parameter is coordinated with the shifting of the transmission to decrease the turbocharger lag associated with shifting and to thereby increase a power output of the engine substantially immediately upon completion of the up-shift.
