Abstract

Provided are an apparatus and a method of generating a travel route, which generate a travel route by using fixed objects positioned at a front side. The apparatus for generating a travel route includes: a space information obtaining unit configured to obtain information on a space, in which a driver'"'"'s vehicle is allowed to travel, by using fixed objects positioned at both sides of the driver'"'"'s vehicle; a travelling direction estimating unit configured to estimate a travelling direction of the driver'"'"'s vehicle based on travelling information about the driver'"'"'s vehicle and information on distances to the fixed objects; and a travel route generating unit configured to generate a travel route of the driver'"'"'s vehicle based on the space information and the travelling direction of the driver'"'"'s vehicle.

Claims

1. An apparatus for generating a travel route, comprising:

a space information obtaining unit configured to obtain information on a space, in which a driver'"'"'s vehicle is allowed to travel, by using fixed objects positioned at both sides of the driver'"'"'s vehicle;

a travelling direction estimating unit configured to estimate a travelling direction of the driver'"'"'s vehicle based on travelling information about the driver'"'"'s vehicle and information on distances to the fixed objects; and

a travel route generating unit configured to generate a travel route of the driver'"'"'s vehicle based on the space information and the travelling direction of the driver'"'"'s vehicle.

2. The apparatus of claim 1, wherein the space information obtaining unit extracts the fixed objects from an image obtained by photographing a front side of the driver'"'"'s vehicle, or an image obtained by collecting laser signals emitted to the front side of the driver'"'"'s vehicle and then reflected and returned.

3. The apparatus of claim 1, wherein the travelling direction estimating unit uses a speed of the driver'"'"'s vehicle and information on a rotation of the driver'"'"'s vehicle as the travelling information.

4. The apparatus of claim 3, wherein the travelling direction estimating unit uses an angular speed or a steering angle as the information on the rotation.

5. The apparatus of claim 1, wherein the travel route generating unit generates the travel route by including a coordinate value of a position in which the driver'"'"'s vehicle is to travel, and a travelling available speed of the driver'"'"'s vehicle.

6. The apparatus of claim 1, further comprising:

a travel route selecting unit configured to select one travel route based on whether a moving object is positioned in travel routes, and a radius of the rotation of the driver'"'"'s vehicle when two or more travel routes are generated.

7. The apparatus of claim 1, further comprising:

a speed control unit configured to decrease a speed of the driver'"'"'s vehicle when the travel route is not generated for a predetermined time, and sequentially drive the space information obtaining unit, the travelling direction estimating unit, and the travel route generating unit again.

8. The apparatus of claim 1, wherein the apparatus for generating the travel route is driven when the travel route is not generated by using a GPS.

9. The apparatus of claim 1, wherein when only fixed objects positioned at one side of the driver'"'"'s vehicle are extracted, the space information obtaining unit obtains the space information based on the fixed objects extracted at one side of the driver'"'"'s vehicle, and a width obtained by adding a predetermined value to a width of the driver'"'"'s vehicle, and

when the fixed objects are not extracted at both sides of the driver'"'"'s vehicle, the space information obtaining unit recognizes both lines and obtains the space information.

10. A method of generating a travel route, comprising:

obtaining information on a space, in which a driver'"'"'s vehicle is allowed to travel, by using fixed objects positioned at both sides of the driver'"'"'s vehicle;

estimating a travelling direction of the driver'"'"'s vehicle based on travelling information about the driver'"'"'s vehicle and information on distances to the fixed objects; and

generating a travel route of the driver'"'"'s vehicle based on the space information and the travelling direction of the driver'"'"'s vehicle.
