Mean rate decision method for clutch motor

A mean rate decision method for a clutch motor driving a clutch, in a system configured so that the clutch is driven by a transmission control unit (TCU) by electrically receiving a signal from a clutch pedal, the method comprising:

• determining whether the clutch motor and a gear sensor are in an electrical failure state (S110);
• when it is determined the clutch motor and the gear sensor are not in the electrical failure state, determining whether there is a driver's starting intention on the basis of state information on the clutch pedal (S120);
• setting a target position of the clutch motor according to a pedal setting value set by the clutch pedal (S140);
• and
• when it is determined that there is no driver's starting intention and that an actual position of the clutch motor exceeds the target position of the clutch motor, determining a failure of the clutch motor on the basis of an excess movement amount and an excess duration in an excess state (S150).
