    摘要： Disclosed is a clutch control reference value setting method including generating a current-hydraulic pressure model, setting a temporary VKP to a current causing a maximum difference between a model hydraulic pressure and a measured hydraulic pressure, determining that the temporary VKP is valid when a deflection amount calculated from a difference integral value acquired by integrating differences between the model hydraulic pressure and the measured hydraulic pressure while increasing the current is greater than a first reference value under a condition that the first target pressure is applied to the clutch, determining that the temporary VKP is appropriate when a deflection amount calculated from a difference integral value acquired by integrating differences between the model hydraulic pressure and the measured hydraulic pressure while increasing the current is proper under a condition that a second target pressure is applied to the clutch.

    摘要： A clutch control method may include generating a current-hydraulic pressure model by obtaining an increasing slope of a measured hydraulic pressure which is applied to a clutch in accordance with an increase of a primary ramp current while applying the primary ramp current to a solenoid valve that controls hydraulic pressure to be supplied to the clutch; obtaining a difference between a virtual hydraulic pressure according to the current-hydraulic pressure model and a measured hydraulic pressure applied to the clutch for a secondary ramp current while applying the secondary ramp current to the solenoid valve after removing the primary ramp current; performing updating by learning a secondary ramp current, at which the difference between the virtual hydraulic pressure and the measured hydraulic pressure is maximum, as a Volumetric Kiss Point (VKP); and controlling the clutch on the basis of the learned VKP.
