| 20080229727 | NORMALIZING OXYGEN STORAGE CAPACITY(OSC) FOR CATALYST MONITORING - An oxygen storage capacity (OSC) monitoring system for a vehicle having a catalytic converter includes a control module that determines a measured OSC based on an inlet sensor signal (ISS) that is responsive to an oxygen content of exhaust flowing into the catalytic converter. The control module determines a normalization ratio based the measured OSC and determines a PASS/FAIL status of the catalytic converter based on the normalization ratio. | 09-25-2008 |
| 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 |
| 20090217916 | ENHANCED CATALYST PERFORMACE BY ENGINE LOAD ADJUSTMENT - A method comprises operating an engine of a vehicle to provide output torque to an input of a torque converter, determining whether the engine is in a cold start condition, fixing an input shaft of a transmission when the engine is in the cold start condition, and coupling the input shaft of the transmission to an output of the torque converter. A control module comprises a combustion control module that operates an engine of a vehicle to provide output torque to an input of a torque converter, a NPD module that determines whether the engine is in a cold start condition, and a transmission control module that fixes an input shaft of a transmission when the engine is in the cold start condition, wherein the input shaft of the transmission is in communication with an output of the torque converter. | 09-03-2009 |
| 20100107630 | Exhaust temperature and pressure modeling systems and methods - An exhaust control system for a vehicle comprises an exhaust system modeling module and an actuator control module. The exhaust system modeling module estimates an input gas temperature, an output gas temperature, a mass temperature, and a pressure for an exhaust system component of an exhaust system implemented in the vehicle. Exhaust gas flows through the exhaust system component. The actuator control module selectively adjusts an engine operating parameter based on at least one of the input gas temperature, the output gas temperature, the mass temperature, and the pressure. | 05-06-2010 |
