  • Auxiliary pump diagnostic systems and methods
    Patent number: 8116932
    Abstract: A system includes an auxiliary pump that provides pressurized fluid to a transmission during an engine auto stop/start event. A mechanical pump provides pressurized fluid to a transmission during engine operation after the engine auto stop/start event. An auxiliary pump diagnostic system includes a slip determination module that determines slip of a torque converter based on an engine speed and a transmission input speed. A fault determination module diagnoses a fault in the auxiliary pump in response to an engine auto start and based on the slip of the torque converter.

  • Combination of cylinder deactivation with flywheel starter generator
    Patent number: 7070537
    Abstract: An engine control system and method incorporates an FSG to reduce engine speed variation for a displacement on demand engine. The control system transitions between a normal operating mode wherein all cylinders of the engine are operating and a cylinder deactivation mode wherein cylinders of the engine are deactivated. The FSG adjusts torque output to said crankshaft to reduce engine speed variation in response to an unrequested change in engine speed. This allows expanded use of cylinder deactivation. Cylinder deactivation allows reduced fuel consumption when the engine and the FSG are used in generator mode.
