Abstract
A vehicle speed controller includes a processor configured to detect a current lane in which a vehicle is traveling, detect a start point at which a curved road section starts within a predetermined distance ahead of the vehicle, estimate the curvature of the current lane in the road section, determine whether the current lane is a fast lane or a slow lane, set a reference speed of the vehicle so that the reference speed decreases as the curvature of the current lane increases and that the reference speed is greater when the current lane is the fast lane than when the current lane is the slow lane, and control the speed of the vehicle so that the speed of the vehicle at the start point of the road section will not be greater than the reference speed.
