1. A method for determining deterioration of a dry clutch mounted between an engine and a motor of a hybrid vehicle, the method comprising steps of:
determining whether an entry condition to determine the deterioration of the dry clutch is satisfied; determining roughness of the dry clutch when the entry condition is satisfied; calculating a deviation between the roughness of the dry clutch and a reference value; comparing the deviation with a threshold value; increasing a roughness counter of the dry clutch when the deviation is larger than the threshold value; comparing the roughness counter of the dry clutch with a boundary value; and determining that the dry clutch deteriorates when the roughness counter of the dry clutch is larger than the boundary value, wherein the roughness of the dry clutch is at least any one of a change in an engine angular velocity, a change in an engine angular acceleration, and a change in a period of the engine angular velocity. |
