Abstract
Disclosed herein is an apparatus and method for controlling the travel speed of a vehicle using information about a road or at least one portion thereof ahead of the vehicle. The apparatus includes a forward image sensor for photographing a forward road or portion(s) thereof, acquiring image data, and extracting information about the forward road or portion(s) from the image data using a Kalman filter. A control unit calculates a target speed required for the vehicle to travel using the forward road information. With the apparatuses and methods, vehicle safety and driving comfort can be improved.
Claims6
An apparatus for controlling a travel speed of a vehicle, comprising:
- a forward image sensor for photographing a road or at least a portion thereof ahead of the vehicle, acquiring image data, and extracting information about the forward road from the image data using a Kalman filter;
- a control unit for calculating a speed required for the vehicle to travel using the forward road portion information;
- and
- a driving unit for controlling a travel operation of the vehicle depending on the calculated vehicle speed.
A method of controlling a travel speed of a vehicle, comprising:
- acquiring image data of a road or at least a portion thereof ahead of the vehicle;
- extracting lane-dividing lines from the image data;
- extracting point coordinates of the lane-dividing lines from the extracted lane-dividing lines;
- calculating information about the forward road or portion thereof using the point coordinates of the lane-dividing lines;
- determining a target speed of the vehicle using the calculated forward road portion information;
- and
- controlling a travel operation of the vehicle depending on the determined target speed.
