Abstract

A vehicle that includes a side-view mirror, at least one sensor disposed in the side-view mirror, and configured to transmit a signal to an object, and to receive a signal reflected from the object is provided. The vehicle further includes a controller that generates driving information based on the signal received by the sensor. The controller corrects distortion of the signal generated by the side-view mirror to generate the driving information. Accordingly, space recognition and obstacle detection for the surrounding environment of the vehicle is capable of being performed using the three dimension sensor.

Claims

1. A vehicle, comprising:

a side-view mirror,

at least one sensor disposed in the side-view mirror, and configured to transmit a signal to an object and receive a signal reflected from the object; and

a controller configured to generate driving information based on the signal received by the sensor,

wherein the controller is configured to correct distortion of the transmitted signal and the received signal of the sensor to generate the driving information, and

wherein the distortion corrected by the controller is generated by at least one of a cover of the side-view mirror and a mirror of the side-view mirror.

2. The vehicle according to claim 1, wherein the controller is configured to correct refraction of the signal generated when the signal is transmitted through the cover or the mirror of the side-view mirror.

3. The vehicle according to claim 2, wherein the controller is configured to correct the distortion of the signal based on a thickness of the mirror of the side-view mirror and an incident angle of the signal transmitted from the sensor.

4. The vehicle according to claim 2, wherein the controller is configured to correct the distortion of the signal based on a thickness of the cover of the side-view mirror and an incident angle of the signal transmitted from the sensor.

5. The vehicle according to claim 1, wherein the cover and the mirror further include a material disposed thereon to enable the signal to be transmitted through the cover and the mirror.

6. The vehicle according to claim 5, wherein the mirror transmits light of infrared wavelengths and reflects light of visible wavelengths.

7. The vehicle according to claim 5, wherein a filter configured to transmit light of infrared wavelengths is coated on the outer surface of the cover.

8. The vehicle according to claim 1, further comprising another sensor disposed in a front portion and a rear portion of the vehicle.

9. The vehicle according to claim 8, wherein the controller is configured to generate the driving information based on information received by the sensor disposed in the side-view mirror and the other sensor disposed in the front portion and the rear portion of the vehicle.

10. A method of controlling a vehicle including at least one sensor disposed in a side-view mirror, comprising:

transmitting, by a controller, a signal to an object and receiving a signal reflected from the object; and

generating by the controller, driving information based on the signal received by the sensor,

wherein the generating of the driving information includes correcting distortion of the transmitted signal and the received signal to generate the driving information, and

wherein the distortion corrected by the controller is generated by at least one of a cover of the side-view mirror and a mirror of the side-view mirror.

11. The method according to claim 10, wherein the correcting of the distortion of the signal includes correcting by the controller, refraction of the signal generated when the signal is transmitted through the cover or the mirror of the side-view mirror.

12. The method according to claim 10, wherein the mirror transmits light of infrared wavelengths and reflects light of visible wavelengths.

13. The method according to claim 10, wherein a filter configured to transmit light of infrared wavelengths is coated on the outer surface of the cover.

14. The method according to claim 13, wherein the generating of the driving information includes receiving, by the controller, raw data from the sensor disposed in the side-view mirror and merging the raw data to generate the driving information.

15. The method according to claim 14, wherein the generating of the driving information includes performing, by the controller, coordinate transformation on the raw data with respect to the reference point of the vehicle and merging the resultant data to generate the driving information.

16. The method according to claim 15, wherein the coordinate transformation includes performing by the controller, rotational transformation on the raw data.

17. The method according to claim 16, wherein the coordinate transformation includes performing by the controller, translational transformation on the raw data.

18. The method according to claim 13, wherein the generating of the driving information includes generating, by the controller, driving information with respect to the sensor and merging the created driving information with respect to the reference point of the vehicle.
