Abstract
A method for controlling a propulsion system of a motor vehicle includes: optimizing both torque control and fuel economy during transient operating conditions; performing a steady state control enable function to identify when steady state operating conditions are present including: determining a commanded axle torque; obtaining a measured actual axle torque; and identifying when the commanded axle torque is substantially equal to the measured actual axle torque and outputting a signal; and further includes: directing the signal output from the control enable function to each of an integral action calculator and a Ym filter; performing an integral action calculation to identify an axle torque integral action; and setting a steady state flag when steady state operating conditions are present which fixes system variables directed to optimizing torque control, temporarily ceasing further optimization of torque control when the steady state flag is set.
