Self-learning torque over boost combustion control

A system, comprising:

• an internal combustion engine including a plurality of cylinders and at least one engine sensor;
• an exhaust system configured to receive exhaust from the plurality of cylinders;
• an intake system configured to direct a charge flow to the plurality of cylinders;
• a fuel system including at least one fuel source operable to provide a flow of fuel to the plurality of cylinders;
• and
• a controller connected to the internal combustion engine and the at least one engine sensor, wherein the controller is configured to:
• receive a pressure signal indicative of the charge flow pressure and determine a torque over boost (TOB) error associated with the charge flow pressure;
• learn a TOB offset and learn a charge pressure at the associated charge flow pressure;
• determine an updated TOB error in response to the learned TOB offset, a desired TOB, and a sensed TOB;
• and
• adjust an operating condition of the internal combustion engine in response to the updated TOB error.

An apparatus, comprising:

• an electronic controller operable to:
• determine a pressure in a charge flow to at least one of a plurality of cylinders of an internal combustion engine system;
• determine a torque over boost (TOB) error associated with the pressure in the charge flow;
• learn a TOB offset and a charge pressure at the associated pressure in the charge flow;
• determine an updated TOB error in response to the learned TOB offset, a desired TOB, and a sensed TOB;
• and
• adjust an operating condition of the at least one engine in response to the updated TOB error.
