A method is provided for monitoring a motor within a seat assembly in an automotive vehicle. The method comprises the steps of measuring raw current values drawn by the motor to reposition the seat assembly, temporally dividing the raw current values into sections based on size and variations in the raw current values, filtering the raw current values in each section to obtain filtered current values, detecting local peaks within the filtered current values, and determining a rotational position or a speed of the motor based on the detected local peaks.
