The purpose of present invention is to provide a fail-safe control device for hybrid vehicles which allows the travel distance of a vehicle to be extended in the event of an ON-failure of a second clutch. An integrated controller (10) switches between an HEV mode and an EV mode by controlling a first clutch (CL1) between an engine (Eng) and a motor (MG), and a second clutch (CL2) between the motor (MG) and a continuously variable transmission (CVT). The integrated controller (10) prohibits the transition from the HEV mode to the EV mode when a clutch failure determination unit (30) detects an ON-failure of the second clutch (CL2) while the vehicle is traveling in the HEV mode.
