In accordance with an embodiment of the present invention, provided is an apparatus for controlling the speed of a vehicle. The apparatus for controlling the speed of the vehicle comprises: a pressure sensor which is attached to a suspension of the vehicle and which measures the pressure applied to a wheel of the vehicle; a GPS which receives information on a road on which the vehicle is driving; a driving resistance calculation unit which calculates a driving resistance affecting the driving of the vehicle based on the pressure measured by the pressure sensor and an inclination of the road which is received from the GPS; a driving force calculation unit which calculates a remaining driving force of the vehicle based on the driving resistance and the driving force of the vehicle; and a driving control unit which controls the engine torque of the vehicle and the highest speed of the vehicle based on the remaining driving force. The present invention aims to provide an apparatus for controlling the speed of a vehicle, which is able to control the engine torque of the vehicle.
