Abstract
Disclosed herein is an apparatus and method for controlling the travel speed of a vehicle using information about a road or at least one portion thereof ahead of the vehicle. The apparatus includes a forward image sensor for photographing a forward road or portion(s) thereof, acquiring image data, and extracting information about the forward road or portion(s) from the image data using a Kalman filter. A control unit calculates a target speed required for the vehicle to travel using the forward road information. With the apparatuses and methods, vehicle safety and driving comfort can be improved.
