1. An automatic driving control system, comprising:
- a road curvature calculating unit that receives shape information of a road ahead from a navigation to calculate curvatures of the road ahead;
an optimum speed calculating unit that calculates optimum speeds on the basis of the curvatures of the road calculated by the road curvature calculating unit and selects speed control points; and
a target acceleration calculating unit that receives information from the optimum speed calculating unit and calculates a target acceleration on the basis of the calculated optimum speeds, the control points, and a current speed of a vehicle.
