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.
