Abstract:
A method for controlling a speed of a vehicle comprising:(a) receiving data about a curvature of a road curve and a distance to the road curve, and calculating an appropriate speed of the vehicle at the road curve; (b) determining whether a current speed of the vehicle is higher than the appropriate speed, and calculating an arrival time interval that it will take for the vehicle running at the current speed to arrive at the road curve if it is determined that the current speed of the vehicle is higher than the appropriate speed; (c) calculating a deceleration time interval that it will take for the current speed of the vehicle to be decelerated to the appropriate speed; and (d) determining whether the current speed of the vehicle is equal to or smaller than the appropriate speed, and forcibly decelerating the vehicle to the appropriate speed if it is not.
