ABSTRACT:
Prediction of the torque and speed of an internal combustion engine at a subsequent engine angular position at which engine control commands are to be issued include information on a steady state torque estimation in accord with a set of engine parameters, an estimated torque production delay value, and prior predictions of engine speed and torque. Correction values reflect differences between previous predicted values and corresponding measurements, when such measurements become available, such correction values being applied to refine the predictions.
