ABSTRACT:
A method controlling a hybrid electric vehicle. The hybrid electric vehicle includes a power transfer unit having a plurality of gear ratios and at least one power source adapted to drive the power transfer unit. The method includes calculating a speed ratio value, comparing the speed ratio value to a threshold value, and inferring a torque disturbance if the speed ratio value is greater than the threshold value.
