Abstract
Disclosed is a system and method for controlling a speed of a vehicle on a curved road according to the present invention. The system for controlling a speed of a vehicle on a curved road according to the present invention includes: a trace corrector configured to correct a trace of a curved road on which the vehicle is to be driven; a curvature calculator configured to calculate a curvature based on feature points of the corrected driving trace; a proper speed calculator configured to calculate a proper speed for each feature point of the driving trace based on the calculated curvature; and a curved road goal acceleration calculator configured to determine a speed control point for controlling a speed based on the calculated proper speed, and to calculate a curved road goal acceleration of the determined speed control point.
