Abstract: A system and method are provided for hybrid electric internal combustion engine applications. A motor-generator, a narrow switchable coupling and a torque transfer unit are arranged in the constrained environment at the front of an engine. The motor-generator is preferably laterally offset from the switchable coupling, which is co-axially-arranged with the engine crankshaft. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated when the coupling is engaged.

Abstract: A hybrid electric vehicle control system and process initiates active charging and power rationing control strategies in accordance with determining that a predicted state of charge of an electrical energy storage unit during an anticipated period of non-driving will be below an anticipated energy consumption during the anticipated period of non-driving. The determination is made, and the active charging and rationing are initiated, in advance of the period of non-driving in order to ensure that a state of charge of the electrical energy storage unit is sufficient to supply the anticipated energy consumption during the period of non-driving.
