Abstract

An apparatus and method for a driving guide of a vehicle are provided and include a sensor unit that has at least one sensor mounted within the vehicle. In addition, a controller is configured to sense obstacles positioned at a front and side of the vehicle using sensing information received from the sensor unit and arrange data for the obstacles based on an angle to determine whether a passage is present in front of the vehicle. In addition, the controller is configured to provide the driving guide of the checked passage.

Claims

1. An apparatus for a driving guide of a vehicle, the apparatus comprising:

a sensor unit that includes at least one sensor mounted within the vehicle; and

a controller configured to;

sense obstacles positioned at a front and a side of the vehicle using sensing information received from the sensor unit;

arrange data for the obstacles based on an angle;

calculate a reference axis along a center angel between a first and second obstacle the sensed obstacles;

calculate a first distance between the reference axis and the first obstacle and second distance between the reference axis and the second obstacle;

determine whether a passage between the first and second obstacle through which the vehicle can pass is present based on a sum of the first and second distance; and

provide the driving guide for the checked passage.

2. The apparatus for the driving guide of the vehicle according to claim 1, wherein the data for the obstacles is configured of a plurality of points of the obstacles and at least one line that connects the plurality of points.

3. The apparatus for the driving guide of the vehicle according to claim 2, wherein the controller is further configured to arrange the plurality of points of the obstacles based on an angle of a polar coordinate system and arrange data between a plurality of obstacles based on the angle of the polar coordinate system.

4. The apparatus for the driving guide of the vehicle according to claim 3, wherein the controller is further configured to calculate a width of the passage using at least two points of the passage based on the arranged data.

5. The apparatus for the driving guide of the vehicle according to claim 1, wherein the controller is further configured to determine that the passage is not present in front of the vehicle when the obstacles are present in front of the vehicle.

6. A method for a driving guide of a vehicle, the method comprising:

analyzing, by a controller, sensing information received from a sensor unit that includes at least one sensor mounted within the vehicle;

sensing, by the controller, obstacles positioned at a front and a side of the vehicle based on the analyzed result;

arranging, by the controller, data for the sensed obstacles based on an angle;

calculating, by the controller, a reference axis along a center angle between a first and second obstacle of the sensed obstacles;

calculating, by the controller, a first distance between the reference axis and the first obstacle and a second distance between the reference axis and the second obstacle;

determining, by the controller, whether a passage between the first and second obstacle through which the vehicle can pass is present based on the sum of the first and second distance; and

providing, by the controller, the driving guide for the checked passage.

7. The method for the driving guide of the vehicle according to claim 6, wherein the arranging of the data for the obstacles according to the angle includes:

extracting, by the controller, data for the obstacles for a plurality of points of the obstacles and at least one line that connects the plurality of points to each other; and

arranging, by the controller, the plurality of points of the obstacles based on an angle of a polar coordinate system and arranging data between a plurality of obstacles based on the angle of the polar coordinate system.

8. The method for the driving guide of the vehicle according to claim 7, further comprising:

after determining whether the passage is present, calculating, by the controller, a width of the passage using at least two points of the passage based on the arranged data.

9. The method for the driving guide of the vehicle according to claim 7, wherein the determining of whether the passage is present further includes:

determining, by the controller, whether the obstacles are present in a direction in which the vehicle is moving; and

determining, by the controller, that the passage is not present in the direction in which the vehicle is moving when the obstacles are present.

10. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that analyze sensing information received from a sensor unit that includes at least one sensor mounted within the vehicle;

program instructions that sense obstacles positioned at a front and a side of the vehicle based on the analyzed result;

program instructions that arrange data for the sensed obstacles based on an angle;

program instructions that calculate a reference axis along a center angle between a first and second obstacle of the sensed obstacles;

program instructions that calculate a first distance between the reference axis and the first obstacle and a second distance between the reference axis and the second obstacle;

program instructions that provide the driving guide for the checked passage.

11. The non-transitory computer readable medium of claim 10, wherein the data for the obstacles is configured of a plurality of points of the obstacles and at least one line that connects the plurality of points.

12. The non-transitory computer readable medium of claim 11, further comprising:

program instructions that arrange the plurality of points of the obstacles based on an angle of a polar coordinate system and arrange data between a plurality of obstacles based on the angle of the polar coordinate system.

13. The non-transitory computer readable medium of claim 12, further comprising:

program instructions that calculate a width of the passage using at least two points of the passage based on the arranged data.

14. The non-transitory computer readable medium of claim 10, further comprising:

program instructions that determine that the passage is not present in front of the vehicle when the obstacles are present in front of the vehicle.
