Abstract
A method to determine and control engine torque in an internal combustion engine. The method may significantly reduce torque strategy calculations and the calibration complexity.
Claims10
A method for determining engine torque loss in an internal combustion engine for an engine controlled by a torque control strategy, the method comprising:
- determining inactive cylinder torque losses of said engine;
- determining active cylinder torque losses of said engine;
- and
- determining an engine torque loss by summing said inactive cylinder torque loss and said active cylinder torque loss.
7-15. (canceled)
A system for operating an internal combustion engine with electromechanical valves, the system comprising:
- a cylinder with at least an electromechanical intake valve and at least an mechanically actuated exhaust valve that can be controlled to adjust valve opening and closing events relative to a crankshaft location;
- and
- a controller to adjust said electromechanical valve timing and said mechanically actuated valve timing.
A computer readable storage medium having stored data representing instructions executable by a computer to control an internal combustion engine of a vehicle, said storage medium comprising:
- instructions for determining inactive cylinder torque losses of said engine;
- determining active cylinder torque losses of said engine;
- and
- determining an engine torque loss by summing said inactive cylinder torque loss and said active cylinder torque loss.
