Patent application number | Description | Published |
20120283936 | Method and System for Engine Speed Control - Methods and systems are provided for accurately determining cylinder fueling errors during an automatic engine restart. Fueling errors may be learned during a preceding engine restart on a cylinder-specific and combustion event-specific basis. The learned fueling errors may then be applied during a subsequent engine restart on the same cylinder-specific and combustion event-specific basis to better anticipate and compensate for engine cranking air-to-fuel ratio deviations. | 11-08-2012 |
20130110367 | VEHICLE SPEED LIMITING AND/OR CONTROLLONG SYSTEM THAT IS RESPONSIVE TO GPS SIGNALS | 05-02-2013 |
20130226439 | METHOD FOR CONTROLLING AN ENGINE - Methods and systems for controlling an engine that may be automatically stopped and started are presented. In one example, a method adjusts an amount of current to an electric device applying torque to an engine to adjust an amount of air that is pumped through the engine to a catalyst. The methods and systems may reduce engine emissions. | 08-29-2013 |
20140067238 | METHOD AND SYSTEM FOR IMPROVING STOPPING AND STARTING OF A TURBOCHARGED ENGINE - A system and method for improving engine starting and stopping is described. In one example, turbine vanes are adjusted to increase engine exhaust backpressure to reduce engine stopping time and to limit engine speed overshoot during engine starting. The system and method may reduce engine emissions and improve a vehicle driving experience. | 03-06-2014 |
20140074376 | METHOD AND SYSTEM FOR ENGINE SPEED CONTROL - Methods and systems are provided for accurately determining cylinder fueling errors during an automatic engine restart. Fueling errors may be learned during a preceding engine restart on a cylinder-specific and combustion event-specific basis. The learned fueling errors may then be applied during a subsequent engine restart on the same cylinder-specific and combustion event-specific basis to better anticipate and compensate for engine cranking air-to-fuel ratio deviations. | 03-13-2014 |
20140251267 | METHOD AND SYSTEM FOR IMPROVING ENGINE STARTING - A system and method for operating an engine is described. In one example, engine boost pressure is adjusted to improve engine starting. | 09-11-2014 |
20140297161 | METHODS AND SYSTEM FOR IMPROVING VEHICLE OPERATION - A method and system improving vehicle operation is presented. In one example, the vehicle data is transmitted between a vehicle and a cloud computer. The cloud computer adjusts engine control parameters and the vehicle is operated based on the adjusted engine control parameters. | 10-02-2014 |
20150226112 | METHOD AND SYSTEM FOR IMPROVING STOPPING AND STARTING OF A TURBOCHARGED ENGINE - A system and method for improving engine starting and stopping is described. In one example, turbine vanes are adjusted to increase engine exhaust backpressure to reduce engine stopping time and to limit engine speed overshoot during engine starting. The system and method may reduce engine emissions and improve a vehicle driving experience. | 08-13-2015 |
