| 20090199560 | CONTROL SYSTEM FOR COLD START EMISSIONS REDUCTION IN HYBRID VEHICLES - A method comprises modifying combustion parameters of an engine of a hybrid vehicle to provide an engine power level insufficient to maintain crankshaft rotation at a desired speed including increasing a temperature of an exhaust gas and reducing an emissions content of the exhaust gas; and supplementing the engine power level with an electric machine of the hybrid vehicle to maintain crankshaft rotation at the desired speed. A control module comprises a cold start combustion control module that modifies combustion parameters of an engine of a hybrid vehicle to provide an engine power level insufficient to maintain crankshaft rotation at a desired speed, wherein the modifying includes increasing a temperature of an exhaust gas, and reducing an emissions content of the exhaust gas; and an electric machine control module that supplements the engine power level using an electric machine of the hybrid vehicle to maintain crankshaft rotation at the desired speed. | 08-13-2009 |
| 20130213043 | Hybrid Drive Device - A hybrid drive device having an engine coupling shaft member, a speed change mechanism, a rotating electrical machine, and an engine connecting clutch. A first lubricating oil passage scatters lubricating oil from radially inside to radially outside of first and second friction plates. A first one-way clutch is interposed between an engine coupling shaft member and a coupling member, and is configured to not be engaged when rotation of the engine coupling shaft member becomes lower than rotation of the coupling member. A second one-way clutch is configured not to be engaged when rotation of the rotating electrical machine becomes lower than rotation of the coupling member. An engine driven oil pump generates an oil pressure to be supplied by a driving force of the internal combustion engine or a driving force of the rotating electrical machine regardless of engagement or disengagement of the engine connecting clutch. | 08-22-2013 |
