Abstract
Official abstract text for this publication.
A controller for controlling an internal combustion engine of a vehicle is disclosed. The controller includes at least one real-time dynamic computational model of at least a part of the internal combustion engine, at least one offline optimized set-point as a first input to the computational model, at least one physical engine sensor input as a second input to the computational model, and a real-time optimizer configured to adjust at least one engine control signal on the basis of at least one output of the computational model in such a way that a deviation from a set-point is at least decreased.
First claim
Opening claim text (preview).
What is claimed is: 1 . A controller for an internal combustion engine, comprising: a real-time dynamic computational model of a performance of a part of the internal combustion engine; a control target related to engine performance or emissions or fuel consumption; an offline optimized control set-point as a first input to the computational model; a physical engine sensor input as a second input to the computational model; and a real-time optimizer configured to adjust an engine control signal on a basis of an output of the computational model such that a deviation from the control target is at least decreased. 2 . The controller according to claim 1 , wherein the output is related to engine performance or emissions or fuel consumption. 3 . The controller according to claim 1 , wherein the second input is a recorded sensor or actuator signal value. 4 . The controller according to claim 1 , wherein the control target is related to combustion phasing or an engine emissions output. 5 . The controller according to claim 1 , wherein an injection timing, an injector actuator setting, an exhaust gas recirculation actuator setting, an injection pressure, and a turbocharger actuator setting are inputs to the computational model. 6 . The controller according to claim 1 , wherein the real-time optimizer regulates at least one of an injection timing, an injector actuator setting, an exhaust gas recirculation actuator setting, an injection pressure, and a turbocharger actuator setting. 7 . The controller according to claim 1 , wherein the real-time optimizer includes a function related to a deviation between the output and the control target. 8 . A method for controlling an internal combustion engine by a controller according to claim 1 .
