Abstract

A vehicle includes a sensing unit configured to sense an object in a surrounding area of the vehicle, an output unit configured to output a notification about a pedestrian detected in the surrounding area, and a control unit configured to recognize whether the object is the pedestrian based on sensing signals delivered from the sensing unit and control the output unit to thereby output the notification when the pedestrian is recognized.

Claims

1. A vehicle, comprising:

a sensing unit configured to sense an object in a surrounding area of the vehicle;

an output unit configured to output a notification about a pedestrian detected in the surrounding area; and

a control unit configured to recognize whether the object is the pedestrian based on sensing signals delivered from the sensing unit and control the output unit to thereby output the notification when the pedestrian is recognized

wherein the output unit comprises;

a display unit configured to display at least one selected from the group consisting of a symbol, a message and a sign corresponding to the notification about the pedestrian in response to a control signal outputted from the control unit,

a speaker unit configured to output a notification sound corresponding to the notification about the pedestrian in response to the control signal outputted from the control unit,

a lighting unit configured to illuminate the pedestrian or a peripheral region of the pedestrian in response to the control signal outputted from the control unit, and

a projector configured to project a direction indicator indicating a traveling direction of the vehicle,

wherein the control unit is configured to control the projector to project, onto the ground around the pedestrian, the direction indicator indicating a traveling direction of the vehicle when the pedestrian is recognized.

2. The vehicle according to claim 1, wherein:

the display unit is arranged to display the notification about the pedestrian toward a front area of the vehicle;

the speaker unit is arranged to output the notification sound toward the front area of the vehicle; and

the lighting unit is arranged to emit a light toward the front area of the vehicle.

3. The vehicle according to claim 1, further comprising:

a camera unit configured to filming a front area of the vehicle in response to a control signal outputted from the control unit.

4. The vehicle according to claim 3, wherein the control unit is configured to recognize whether the object is movable based on the sensing signals, and determine whether a movable object is the pedestrian based on an image captured by the camera unit.

5. The vehicle according to claim 1, wherein the sensing unit comprises:

a front sensor configured to sense a front area of the vehicle;

a rear sensor configured to sense a rear area of the vehicle; and

a side sensor configured to sense side areas of the vehicle.

6. The vehicle according to claim 1, wherein, when the pedestrian is recognized, the control unit makes the display unit show that an icon of a specific shape tracks along with the pedestrian.

7. The vehicle according to claim 6, wherein icon'"'"'s specific shape is an eye or a pupil of the eye.

8. The vehicle according to claim 1, wherein, when the pedestrian is recognized, the control unit is configured to make an illumination unit emit a notification light so that the notification light is displayed on a front hood of the vehicle according to a movement direction of the pedestrian.

9. The vehicle according to claim 8, wherein the notification light comprises a particular shape or color which is distinguishable from a head lamp.

10. The vehicle according to claim 1, wherein the control unit is configured to make the output unit generate a light or a sound having a directivity toward the pedestrian when the pedestrian is recognized.

11. The vehicle according to claim 10, wherein the light or the sound having the directivity is moved along with a movement direction of the pedestrian.

12. The vehicle according to claim 1, wherein the control unit is configured to control the display unit to display, on a display screen, a direction indicator indicating the traveling direction of the vehicle when the pedestrian is recognized.

13. A method for providing a pedestrian with vehicle'"'"'s perception, comprising:

sensing an object in a surrounding area of the vehicle;

recognizing whether the object is the pedestrian; and

outputting a notification about the pedestrian detected in the surrounding area

wherein outputting comprises;

when the pedestrian is recognized, checking whether the notification is previously set,

when no notification is previously set, showing a list of notification items about the pedestrian,

recognizing a selected notification item, and

displaying the notification corresponding to the selected notification item,

wherein displaying comprises;

projecting, onto the ground around the pedestrian, a direction indicator indicating traveling direction of the vehicle when the pedestrian is recognized.

14. The method according to claim 13, wherein outputting the notification further comprises:

when the notification is preset, displaying the notification corresponding to the pedestrian.

15. The method according to claim 13, wherein the notification is moved along with pedestrian'"'"'s movement, and the notification comprises at least one of a symbol, a message, a sign, a sound, a lighting, or the combination thereof.

16. The method according to claim 13, wherein recognizing whether the object is the pedestrian comprises:

determining whether the object is movable based on sensing signals delivered from at least one sensor; and

determining whether a movable object is the pedestrian based on an image delivered from a camera.

17. The method according to claim 13, wherein displaying further comprises:

displaying, on a display screen, a direction indicator indicating a traveling direction of the vehicle when the pedestrian is recognized.

18. An apparatus for providing a pedestrian with vehicle'"'"'s perception, equipped with a vehicle, comprising a processing system that comprises at least one data processor and at least one computer-readable memory storing a computer program, wherein the processing system is configured to cause the apparatus to perform a process the comprises:

sensing an object in a surrounding area of the vehicle;

recognizing whether the object is the pedestrian; and

outputting a notification about a pedestrian detected in the surrounding area,

wherein outputting the notification comprises;

displaying at least one selected from the group consisting of a symbol, a message and a sign corresponding to the notification about the pedestrian in response to a control signal outputted from a control unit,

outputting a notification sound corresponding to the notification about the pedestrian in response to the control signal outputted from the control unit, and

illuminating the pedestrian or a peripheral region of the pedestrian in response to the control signal outputted from the control unit,

wherein displaying comprises;

projecting, onto the ground around the pedestrian, a direction indicator indicating a traveling direction of the vehicle when the pedestrian is recognized.

19. The apparatus according to claim 18, wherein displaying further comprises:

displaying, on a display screen, a direction indicator indicating a traveling direction of the vehicle when the pedestrian is recognized.
