20080281496Cam phaser compensation in a hybrid vehicle system - A method of regulating a torque output of an internal combustion engine in a hybrid electric vehicle includes determining whether a cam phaser system of the engine is in one of an inactive state and an active state and monitoring at least one engine operating parameter. An engine torque array is selected from a plurality of engine torque arrays based on the one of the inactive state and the active state. An available engine torque is determined based on the engine torque array and the at least one engine operating parameter and the engine is regulated based on the available engine torque.11-13-2008
20090012665Use of Torque Model at Virtual Engine Conditions - A torque estimation system for a vehicle comprises an operating parameter module, a torque estimation module, and an estimation control module. The operating parameter module determines an estimated engine operating parameter based on engine speed. The torque estimation module estimates engine torque based on the engine speed and the estimated engine operating parameter. The estimation control module provides a plurality of engine speeds to the operating parameter module and the torque estimation module to determine estimated engine torque as a function of engine speed.01-08-2009
20100250089METHOD AND SYSTEM FOR GENERATING A DIAGNOSTIC SIGNAL OF AN ENGINE COMPONENT USING AN IN-CYLINDER PRESSURE SENSOR - A method and a control module for diagnosing an engine component function includes a comparison module comparing an in-cylinder pressure signal to a threshold and a fault indication module generating a diagnostic signal for an engine component in response to comparing.09-30-2010
20110054744SYSTEM AND METHOD FOR DETERMINING ENGINE FRICTION - An engine control system includes a combustion torque determination module, a friction torque determination module, and a control module. The combustion torque determination module determines a combustion torque of an engine based on pressure inside a cylinder of the engine during an engine cycle. The friction torque determination module determines friction torque of the engine based on the combustion torque, acceleration of an engine crankshaft, effective inertia of the engine crankshaft, and a pumping loss in the cylinder during the engine cycle. The control module adjusts an operating parameter of the engine based on the friction torque.03-03-2011
20110056278SYNCHRONIZATION DIAGNOSTIC SYSTEMS AND METHODS FOR ENGINE CONTROLLERS - An engine controller diagnostic system includes a cylinder identification (ID) comparison module and a synchronization diagnostic module. The cylinder ID comparison module compares a first cylinder ID associated with a first controller with a second cylinder ID associated with a second controller. The synchronization diagnostic module determines a synchronization status of the first controller based on a comparison between the first cylinder ID and the second cylinder ID.03-10-2011
20110087419CYLINDER PRESSURE MEASUREMENT SYSTEM AND METHOD - An engine control system includes a piston movement modeling module, a cylinder volume determination module, and a cylinder pressure estimation module. The piston movement modeling module models movement of a piston within a corresponding cylinder based on angular change of an engine crankshaft. The cylinder volume determination module determines a volume of the cylinder based on an angular position of the engine crankshaft and the modeled movement of the piston. The cylinder pressure estimation module estimates pressure in the cylinder based on the determined volume, an intake manifold absolute pressure (MAP), an intake valve timing, an exhaust valve timing, and an exhaust back pressure (EBP).04-14-2011
20110144838FUEL ECONOMY WITH A DUAL OVERHEAD CAM ENGINE AND A STRONG HYBRID - A method for controlling a powertrain includes operating an engine substantially at wide open throttle, monitoring an output torque request, controlling the engine input torque by controlling a valve overlap setting for a cylinder of the engine based upon the output torque request wherein controlling the valve overlap setting for the cylinder modulates a residual burnt gas fraction within the cylinder utilizing at least one of an extended low slope portion of an exhaust valve closing curve and an extended low slope portion of an intake valve opening curve, and controlling an electric machine input torque based upon the output torque request and a time-lag difference between the output torque request and the controlled engine input torque.06-16-2011
