Abstract
Systems and methods for using pedal position and/or pedal change rate in the fuel side and/or air side control of an engine. By knowing the pedal position and/or pedal rate, an engine controller may anticipate future fuel and/or air needs of the engine, and adjust the fuel profile and/or air profile to meet those anticipated needs. This may help improve the responsiveness, performance and emissions of the engine.
Claims64
A method for controlling an internal combustion engine, the engine having a fueling profile that defines the fuel that is provided to the engine, and an air charge profile that defines the air that is provided to the engine, the fueling profile being at least partially controlled by a pedal position, the method comprising the steps of:
- identifying a pedal change rate of the pedal position;
- and
- controlling the air profile based, at least in part, on the pedal change rate.
24-26. (canceled)
A method for controlling a diesel engine that includes a turbocharger, the diesel engine having a fueling profile defining the fuel that is provided to the diesel engine and a turbo boost profile at least in part defining the air that is provided to the diesel engine, the diesel engine having a pedal position, the method comprising the steps of:
- identifying a pedal change rate of the pedal position;
- and
- controlling the turbo boost profile based, at least in part, on the pedal change rate.
A method for controlling a diesel engine that includes a turbocharger, the diesel engine having a fueling profile defining the fuel that is provided to the diesel engine and a turbo boost profile defining the air that is provided to the diesel engine, the diesel engine having a pedal position, the method comprising the steps of:
- identifying a pedal change rate of the pedal position;
- and
- controlling the fueling profile based, at least in part, on the pedal change rate.
A method for controlling an internal combustion engine, the engine having an exhaust recirculation valve for providing a selected amount of exhaust gas to the intake air of the engine, the engine having a pedal position, the method comprising the steps of:
- identifying a pedal change rate of the pedal position;
- and
- controlling the amount of exhaust gas recirculation that is provided to the intake air of the engine based, at least in part, on the pedal change rate.
61-68. (canceled)
A method for controlling an internal combustion engine, the engine having one or more controllable engine parameters that affect the performance of the engine, the method comprising the steps of:
- identifying a pedal change rate of a pedal position;
- and
- controlling one or more of the engine parameters based, at least in part, on the pedal change rate.
