Abstract: An apparatus of estimating a vehicle weight may include: an acceleration detector detecting a longitudinal direction acceleration of the vehicle; a data detector detecting state data to estimate the vehicle weight; an engine clutch disposed between an engine and a drive motor and selectively connecting the engine to the drive motor; an integrated starter-generator for starting the engine and generating electric energy; and a vehicle controller calculating a basic vehicle weight based on an engine torque, a motor torque and the longitudinal direction acceleration detected by the acceleration detector. The vehicle controller estimates a final vehicle weight based on the basic vehicle weight and a predetermined weight when an estimating entrance condition is satisfied from the state data.

Abstract: 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.
