Abstract
A vehicle speed control system includes a speed limit obtaining unit that obtains a speed limit for a road in front of a vehicle, a curve information obtaining unit that detects a curve on the road, and calculates a distance from a current position of the vehicle to a start position of the curve and a radius of curvature of the curve, a calculating unit that calculates a first maximum speed at which the vehicle does not deviate from a traveling lane on the curve, based on the radius of curvature, and a control unit that controls the vehicle such that a speed of the vehicle at the start position becomes substantially equal to the first maximum speed, when the first maximum speed does not exceed the speed limit.
