A clutch control method for a vehicle includes steps of: calculating, by a controller, an estimated clutch torque by substituting a plurality of parameters, and a sensed stroke of a clutch actuator into a predetermined characteristic function; updating, by the controller, the parameters as new values by a prediction error method using a torque error, which is a difference between a reference clutch torque and the estimated clutch torque; calculating a desired stroke by substituting a desired clutch torque and the updated parameters into a predetermined characteristic inverse function; and driving the clutch actuator based on the calculated desired stroke to control the clutch by the controller. The plurality parameters represent physical properties of a clutch, and the predetermined characteristic function represents characteristics of a clutch transmission torque to a clutch actuator stroke. In addition, the predetermined characteristic inverse function represents a clutch actuator stroke to a clutch transmission torque.
