Abstract
A control method for a clutch of a hybrid electric vehicle including a series and parallel type of hybrid transmission, may include determining whether the hybrid electric vehicle may be operating as the parallel type, determining a hydraulic pressure of the clutch according to a demand torque of a driver when the hybrid electric vehicle may be operating as the parallel type, determining a target value of torque blending which blends a front side torque of the clutch with a motor torque and performing the torque blending, increasing the target value of the torque blending until a clutch slip may be generated, stopping the torque blending when the clutch slip may be generated, and learning a hydraulic pressure of the clutch corresponding to the front side torque of the clutch at a time when the clutch slip may be generated.
