    • PROBLEM TO BE SOLVED: To solve the problem wherein the improvement of driver's comfort during acceleration when a vehicle travels along a curve and comes out of the curve has not been taken into consideration in the conventional technologies.
      SOLUTION: A vehicle speed control system includes: a road shape recognition unit which recognizes a road shape; a target-speed setting unit which sets a target speed, according to the road shape; a speed control unit which controls the self vehicle's speed according to the target speed; a parameter detecting unit which detects at least one of parameters indicating the driver's manipulated variable of steering, the yaw rate of the self vehicle, and lateral acceleration of the self vehicle; and a first acceleration determining unit, which after the speed control unit has performed deceleration, determines whether to accelerate the self vehicle, according to reference parameters corresponding to the road shape and the self vehicle's speed and parameters detected by the parameter detecting unit, wherein when the first acceleration determining unit has determined to accelerate, the target-speed setting unit sets the target speed of the self vehicle according to a predetermined acceleration.
