1. A control method for a magnetic powder clutch system including a magnetic powder clutch having an input shaft connected to an engine and an output shaft, comprising the steps of:

  • determining an energizing strength of the magnetic powder clutch based on a target transmitting torque;

    correcting the energizing strength with a correction factor determined based on a specific powder clutch;

    energizing the magnetic powder clutch with the corrected energizing strength;

    determining an actual transmitting torque of the magnetic powder clutch when a change in a detected transmitting torque is smaller than a preset value;

    calculating a difference between the target transmitting torque and the actual transmitting torque; and

    updating the correction factor according to the calculated difference.
