Abstract

A clutch control method for a vehicle includes: increasing, by a controller, a clutch torque to a refill execution torque at a predetermined first inclination when a predetermined first reference time period has elapsed in a micro-slip state of a clutch; increasing, by the controller, the clutch torque to a refill torque at a predetermined second inclination to initiate refilling of a pressure chamber of a hydraulic-driving actuator with oil in a reservoir tank when the clutch torque reaches the refill execution torque; and maintaining the clutch torque at the refill torque during a predetermined second reference time period.
