Abstract

An automatic speed control device includes: an upper limit lateral acceleration degree setting part for setting an upper limit lateral acceleration degree; a road curvature acquiring part for acquiring a value of a curvature parameter relating to curvature of a road; an upper limit speed setting part for calculating a speed of the vehicle at which if the vehicle runs on that road, the lateral acceleration degree of the vehicle becomes the upper limit lateral acceleration degree and setting the calculated speed as the upper limit speed; and a speed control part for controlling the speed of the vehicle to be less than or equal to the upper limit speed. The upper limit lateral acceleration degree when running on a connecting road is set lower than the upper limit lateral acceleration degree when running on a main road of a motorway.
