Abstract: PURPOSE: An apparatus and a method for protecting the frictional elements of a hybrid vehicle are provided to improve power performance by implementing the mode conversion of a two-mode hybrid vehicle based on sufficient slipping. CONSTITUTION: An apparatus for protecting the frictional elements of a hybrid vehicle includes an engine, a first motor, a second motor, frictional elements, and a controller. The first motor operates based on idle stop and go. The second motor generates driving torque. The frictional elements transfer power or generate counter force. The controller detects the output torque and the speed of an engine, the torque of the first motor, and the torque of the second motor(S203). The controller calculates the corresponding torque and the relative speed of frictional elements(S204). The controller calculates the heating values of the frictional elements(S205). The slipping amounts of the frictional elements are limited based on the heating values of the frictional elements(S207).
