摘要
A method of starting an engine when a starter motor of a hybrid electric vehicle has a failure includes identifying a request for starting the engine in a state where the starter motor has the failure. When the request for starting the engine is made in the state where the starter motor has the failure, a torque or a load of an engine clutch and a pressure of the engine clutch are determined. A torque of a driving motor is set to a smaller torque between a driving motor demanded torque and a torque obtained by subtracting the torque of the engine clutch from a maximum torque of the driving motor. The engine starts with the set torque of the driving motor while controlling the engine clutch.
