Vehicle driving control system and method

A vehicle driving control system comprising:

• a road information device calculating road information of a curved road on which a vehicle drives;
• a road surface information device calculating a road surface condition of a road;
• a neighboring vehicle information device calculating location information or movement information of a neighboring vehicle located close to the vehicle;
• a computing device computing a target speed based on the road information calculated by the road information device, the road surface condition calculated by the road surface information device, and the location information or the movement information of the neighboring vehicle calculated by the neighboring vehicle information device;
• and
• a processor controlling driving of the vehicle based on the computed target speed,
• wherein the road information device is connected to a navigator mounted in the vehicle to calculate a radius of curvature of the curved road based on information obtained from the navigator, and
• wherein the computing device computes a reference speed of the vehicle based on the radius of curvature of the curved road calculated by the road information device, calculates a weight based on the road surface condition calculated by the road surface information device, computes a subtraction speed based on the weight, and computes the target speed by subtracting the subtraction speed from the reference speed.
