Abstract
Provided is an engine power estimation apparatus for estimating an engine power at a gear shift completion time when making a speed change of a vehicle. The engine power estimation apparatus includes a gear shift detection unit configured to detect the speed change of the vehicle; an axle speed estimation unit configured to calculate a target axle speed at the gear shift completion time, using an axle speed and a gear shift time learning value, when the speed change of the vehicle is detected; and an engine power estimation unit configured to calculate a target engine power at the gear shift completion time, using the target axle speed and engine load information.
