| 20080262695 | Engine mode transition utilizing dynamic torque control - A method of operating an engine having a plurality of cylinders, the method comprising of transitioning the engine from a first mode to a second mode, and temporarily adjusting an amount of torque produced by a cylinder of the engine for at least one cycle responsive to a difference in an amount of torque produced by a previous firing cylinder and a subsequent firing cylinder. | 10-23-2008 |
| 20080308069 | ENGINE FUELING CONTROL DURING CYLINDER VALVE MODE TRANSITIONS - A method of control fueling of a cylinder in an internal combustion engine, the cylinder having at least two intake valves, the method comprising of operating in a first mode with one active intake valve and one inactive intake valve during a cycle of the cylinder operating in a second mode with two active intake valves during a cycle of the cylinder and adjusting a fuel injection from an injector configured to deliver fuel through at least the two intake valves, where the fuel injection adjustment is responsive to a transition in modes and based on whether the transition is from the first mode to the second mode, or from the second mode to the first mode. | 12-18-2008 |
| 20090090318 | METHOD FOR CONTROLLING AIR-FUEL RATIO FOR AN ALTERNATING VALVE ENGINE - A method for controlling the air-fuel ratio of an internal combustion engine operating with alternating intake valves is presented. According to the method, engine air-fuel ratio can be adjusted by changing valve timings or fuel during a cylinder cycle. | 04-09-2009 |
| 20100012053 | MULTI-STROKE VARIABLE DISPLACEMENT ENGINE - A vehicle propulsion system and method of operation are presented. As one example, the method includes operating an engine to produce an engine output; transferring the engine output to one or more drive wheels of the vehicle via a transmission; responsive to a first condition, varying torque supplied to the drive wheels by adjusting a relative number of combusting cylinders and deactivated cylinders of the engine; and responsive to a second condition, varying the torque supplied to the drive wheels by adjusting a number of strokes performed by the combusting cylinders per combustion cycle while shifting the transmission between different gear ratios. | 01-21-2010 |
| 20100012088 | ENGINE CONTROL INCLUDING KNOCK COMPENSATION - Systems and methods are described, including one example method of controlling an engine having a cylinder with at least one valve operated by a variable valve mechanism (VVM) having a sensor coupled to the valve, the method comprising: adjusting at least one operating parameter in response to an indication of detonation of a combustible mixture in the cylinder, the indication based on the sensor coupled to the valve. | 01-21-2010 |
| 20100180840 | METHOD FOR CONTROLLING AIR-FUEL RATIO FOR AN ALTERNATING VALVE ENGINE - A method for controlling the air-fuel ratio of an internal combustion engine operating with alternating intake valves is presented. According to the method, engine air-fuel ratio can be adjusted by changing valve timings or fuel during a cylinder cycle. | 07-22-2010 |
| 20110239963 | MULTI-STROKE VARIABLE DISPLACEMENT ENGINE - A vehicle propulsion system and method of operation are presented. As one example, cylinder deactivation and transitioning from four to two strokes is coordinated with transmission shifting to improve vehicle response. Additionally, it is possible to reduce transitions in operating modes to improve drive feel. | 10-06-2011 |
| 20120010767 | HYBRID ELECTRIC VEHICLE AND METHOD OF CONTROL USING PATH FORECASTING - A path-dependent control of a hybrid electric vehicle (HEV) includes segmenting a route into segments, generating a sequence of battery state-of-charge (SoC) set-points for the segments, and controlling the vehicle in accordance with the battery SoC set-points as the vehicle travels along the route. | 01-12-2012 |
| 20120010768 | HYBRID ELECTRIC VEHICLE AND METHOD OF PATH DEPENDENT RECEDING HORIZON CONTROL - A path-dependent control of a hybrid electric vehicle (HEV) includes segmenting an original route into segments. A virtual route based on the remaining portion of the original route is generated once the HEV reaches a current segment of the original route. The virtual route includes a first segment corresponding to the current segment of the original route and a last segment representing at least two other segments of the remaining portion of the original route. Battery SoC set-points for the segments of the virtual route are generated. The vehicle is controlled according to the battery SoC set-point for the first segment of the virtual route as the vehicle travels along the current segment of the original route. | 01-12-2012 |
