An illustrative example method of controlling an engine of a vehicle, includes determining a target pressure curve for a cylinder of the engine, determining a heat release model for the cylinder, determining a mass flow of fuel from the heat release model to achieve the target pressure curve, and automatically controlling opening of an injector of the cylinder of the engine to provide the determined mass flow of fuel to the cylinder.

Method and apparatus for controlling an engine based on a target pressure curve

An illustrative example method of controlling an engine of a vehicle, includes determining a target pressure curve for a cylinder of the engine for a first combustion cycle, determining a heat release model for the cylinder for the first combustion cycle, determining a mass flow of fuel from the heat release model to achieve the target pressure curve during the first combustion cycle, and automatically controlling opening of an injector of the cylinder of the engine during the first combustion cycle to provide the determined mass flow of fuel to the cylinder. The method includes determining a real pressure curve during the first combustion cycle and automatically adjusting at least one of the heat release model or the mass flow for a second, subsequent combustion cycle based on a difference between the target pressure curve and the real pressure curve.
