Abstract

A vehicle and method for controlling the same are provided to improve recognition performance of a camera by irradiating light from a headlamp to an object, which may be recognized by a detection sensor but not by the camera, thereby avoiding a collision by detecting the object using both the camera and detection sensor. The vehicle includes an optical sensor that detects illumination around the vehicle and a detection sensor that detects an object around the vehicle to obtain information regarding at least one of a position and speed of the object. A controller operates a headlamp to irradiate light toward the object based on the position information of the object when the detected illumination is less than a predetermined value.

First claim

What is claimed is:

1. A vehicle, comprising:
an optical sensor configured to detect illumination around the vehicle;
a detection sensor configured to detect an object around the vehicle to obtain at least one of position information of the object and speed information of the object; and
a controller configured to transmit a control signal to operate a headlamp to irradiate light toward the object based on the position information of the object when the illumination around the vehicle detected by the optical sensor is less than a predetermined illumination value of pre-stored illumination data, wherein
the headlamp is configured to irradiate light toward the object based on the control signal, and
the controller is further configured to:
calculate a time to collision (TCC) of the vehicle with the object based on at least one of the position information of the object and the speed information of the object, and
transmit the control signal to operate the headlamp to irradiate light toward the object when the TCC is less than a predetermined time.

2. The vehicle of claim 1 , wherein the controller is configured to:
adjust an amount of light to be irradiated from the headlamp toward the object, based on a distance from the vehicle to the object.

3. The vehicle of claim 1 , wherein the controller is configured to:
adjust an amount of light to be irradiated from the headlamp toward the object, based on the TCC of the vehicle with the object.

4. The vehicle of claim 1 , further comprising:
a capturer configured to capture an image of an object located in a direction in which the light from the headlamp is irradiated, to detect the object.

5. The vehicle of claim 4 , wherein the capturer is configured to:
determine a type of object based on the image captured of the object.

6. The vehicle of claim 4 , wherein the controller is configured to:
determine the object to be subject to collision avoidance control based on at least one of the position information of the object and the speed information of the object and based on the image of the object captured by the capturer.

7. The vehicle of claim 1 , wherein the controller is configured to:
adjust the speed of the vehicle based on the TCC of the vehicle with the object.

8. The vehicle of claim 7 , further comprising:
a speed controller configured to adjust the speed of the vehicle based on the control signal.

9. The vehicle of claim 1 , wherein the detection sensor includes any one of a radar and Light Detection And Radar (LiDAR).

10. A method for controlling a vehicle, comprising:
detecting, by an optical sensor, illumination around the vehicle;
detecting, by a detection sensor, an object around the vehicle to obtain at least one of position information of the object and speed information of the object;
calculating, by a controller, a time to collision (TCC) of the vehicle with the object based on at least one of the position information of the object and the speed information of the object;
transmitting, by the controller, a control signal to operate a headlamp to irradiate light toward the object based on the position information of the object when the illumination around the vehicle detected by the optical sensor is less than a predetermined illumination value of pre-stored illumination data; and
transmitting, by the controller, the control signal to operate the headlamp to irradiate light toward the object when the TCC is less than a predetermined time.

11. The method of claim 10 , wherein transmitting the control signal to operate a headlamp includes:
adjusting, by the controller, an amount of light to be irradiated from the headlamp toward the object, based on a distance from the vehicle to the object.

12. The method of claim 10 , wherein transmitting the control signal to operate a headlamp includes:
adjusting, by the controller, an amount of light to be irradiated from the headlamp toward the object, based on the TCC of the vehicle with the object.

13. The method of claim 10 , further comprising:
capturing, by an imaging device, an image of an object located in a direction in which the light from the headlamp is irradiated, to detect the object.

14. The method of claim 13 , further comprising:
determining, by the controller, a type of the object based on the image captured from the object.

15. The method of claim 13 , further comprising:
determining, by the controller, the object to be subject to collision avoidance control based on at least one of the position information of the object and the speed information of the object and based on the image of the object captured by the imaging device.

16. The method of claim 10 , further comprising:
adjusting, by the controller, the speed of the vehicle based on the TCC of the vehicle with the object.
