First Claim
Patent Images
1. A device for controlling a vehicle speed, comprising:
- a digital map that determines a current location of a vehicle and a curvature of a forward path;
a safe speed determining unit that determines a safe speed of the vehicle based on the curvature of the forward path;
a vehicle speed sensor that measures a travelling speed of the vehicle; and
a controller that controls the vehicle speed such that the vehicle is decelerated when the travelling speed of the vehicle is higher than the safe speed.

Abstract
The present invention relates to a device and a method for controlling a speed of a vehicle. A safe speed of the vehicle is determined based on a curvature of a forward path and weather conditions. When a travelling speed of the vehicle is higher than the safe speed, the speed of the vehicle is controlled such that the vehicle is decelerated.
