Abstract
A method of controlling clutch transfer torque in a hybrid vehicle comprises estimating clutch characteristics from a relation between a control current for a clutch hydraulic valve and a clutch transfer torque corresponding to the control current for the clutch hydraulic valve. With the method, a clutch friction coefficient can be precisely estimated, thereby reducing/eliminating a shock that can occur in the event of the clutch going on or off.
