Abstract: An apparatus of controlling a twin clutch includes: a twin clutch that selectively blocks power supplied from a drive motor to a pair of drive wheels of a vehicle; and a clutch controller that is configured to control the twin clutch by determining target torques applied to respective clutches included in the twin clutch, based on the straight-line driving state detected by the driving information detection unit, determining a correction error based on a difference between actual torques applied to the respective clutches included in the twin clutch when a preliminary activation signal, which is determined based on the target torques, is turned on and a main activation signal, which is determined based on the actual torques applied to the respective clutches, is turned on, determining a balancing control compensation amount based on the correction error, and determining a final control amounts applied to the respective clutches based on the balancing control compensation amount.
