Abstract
A method for emergency driving is carried out in a hybrid vehicle which includes an engine, a first motor connected to the engine through an engine clutch, and a second motor directly connected to the engine so that power transmission is possible, where a DC-link is charged with a counter electromotive force of the first and second motors, generated by driving energy of the vehicle or power of the engine when a main relay is off during driving of the vehicle. The DC-link of which voltage control is performed is used as a power source for the emergency driving of the vehicle. In the emergency driving of the vehicle using the DC-link as the power source, the engine clutch between the engine and the first motor is separated, and the vehicle is then driven by a driving force of the first motor.
