Apparatus for Controlling Speed of Vehicle and Method for the Same

A method for controlling a speed of a vehicle, the method comprising:

• receiving, by a communication device, at least one of a starting point of a speed trap, an end point of the speed trap, a speed limit in the speed trap, an average speed of the vehicle, a traveling distance from the starting point of the speed trap of the vehicle, or a present speed of the vehicle;
• setting, by a target speed setting device, a target point based on the end point of the speed trap;
• setting, by the target speed setting device, a starting point for a target speed based on the set target point;
• determining, by the target speed setting device, whether the vehicle passes through the starting point for the target speed;
• calculating, by the target speed setting device, the target speed based on at least one of the starting point of the speed trap, the speed limit, the average speed, the traveling distance from the starting point of the speed trap, or the set target point when the vehicle has not passed through the starting point for the target speed;
• calculating, by a required acceleration calculating device, the required acceleration based on the calculated target speed, the speed limit, a lower limit of the target speed, an upper limit of the target speed, or the present speed of the vehicle;
• and
• controlling, by a controller, the vehicle based on at least one of the calculated target speed or the calculated required acceleration.
