A method and an apparatus for controlling a hybrid electric vehicle are provided. The apparatus includes a navigation device that provides information regarding a gradient, a speed limit, and a traffic speed of a road. An accelerator pedal position detector detects a position of an accelerator pedal and a brake pedal position detector detects a position of a brake pedal. A vehicle speed detector detects a vehicle speed, a state of charge (SOC) detector detects an SOC of a battery, and a gear stage detector detects a gear stage that is currently engaged. A controller operates the hybrid vehicle based on signals of the navigation device, the accelerator pedal position detector, the brake pedal position detector, the vehicle speed detector, the SOC detector, and the gear stage detector.

A control system for hybrid vehicle for extending a possible travelling distance of the vehicle in the event of clutch failure is provided. The control system is configured to select a first drive mode in which the vehicle is powered by an engine in case an estimated torque transmitting capacity of the clutch in trouble is larger than a first threshold value, and to select a second drive mode in which the vehicle is powered by a motor in case the estimated torque transmitting capacity of the clutch in trouble is smaller than the first threshold value. The control system is further configured to reduce an engine torque to be smaller than the estimated torque transmitting capacity of the clutch in case the first drive mode is selected.
