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.

    一种用于控制机动车辆的推进系统的方法包括:在瞬态操作条件期间优化扭矩控制和燃料经济性;执行稳态控制启用函数以识别何时存在稳态操作条件,包括:确定命令的轴扭矩;获取测得的实际轴扭矩;以及识别所述命令的轴扭矩何时基本上等于所述测得的实际轴扭矩并且输出信号;并且还包括:将从所述控制启用函数输出的信号引导至积分动作计算器和Ym滤波器中的每一个;执行积分动作计算来识别轴扭矩积分动作;以及,当存在稳态操作条件时设置稳态标志,所述稳态标志使针对优化扭矩控制的系统变量固定,从而当设置所述稳态标志时暂时中止对扭矩控制进一步优化。
