Method of directly controlling autonomous vehicle

1. A method of directly controlling an autonomous vehicle, the method comprising steps of:

determining, by an autonomous vehicle control unit, whether there is a request of a first occupant currently having no driving control authority for the autonomous vehicle, for a transfer of the driving control authority by selecting a holographic image for requesting the transfer of the driving control authority;

determining, by the autonomous vehicle control unit, whether there is acceptance of a second occupant currently having the driving control authority, for the request of the first occupant by selecting a holographic image for accepting the transfer of the driving control authority when the second occupant receives the request for the transfer of the driving control authority from the first occupant;

determining, by the autonomous vehicle control unit, a vehicle control mode including a manual driving mode or an autonomous driving mode, in accordance with the first occupant's selecting the holographic image displaying the manual driving mode or the autonomous driving mode according to the acceptance by the second occupant;

performing, by the autonomous vehicle control unit, in accordance with the vehicle control mode selected by the first occupant, driving control of the autonomous vehicle by displaying a holographic image required for the driving control of the autonomous vehicle, changing the holographic image in a predetermined pattern in accordance with a gesture of the first occupant, and

performing, by the autonomous vehicle control unit, the driving control in accordance with the gesture of the first occupant;

wherein the holographic images in the respective steps are implemented by a hologram device connected to the autonomous vehicle control unit required for the driving control, and the holographic images are displayed to the first and second occupants.

2. The method of claim 1 , further including:

verifying, by the autonomous vehicle control unit, whether the first occupant has a driving control ability, when the transfer of the driving control authority is requested by the first occupant.

3. The method of claim 1 , wherein the holographic image for requesting the transfer of the driving control authority and the holographic image for accepting the transfer of the driving control authorityare movable from an initial position spaced apart, with a predetermined distance, from an occupant authorized to select the holographic image to a final position which is a position at which the authorized occupant is able to select the holographic image.

4. The method of claim 1 , further including:

determining, by the autonomous vehicle control unit, whether the first occupant is able to perform manual driving of the autonomous vehicle when the first occupant selects the manual driving mode.

5. The method of claim 1 , further including:

maintaining, by the autonomous vehicle control unit, a previous vehicle control mode when the first occupant does not select the vehicle control mode.

6. The method of claim 1 , wherein the holographic image required for the driving control includes at least one of holographic images related to steering, acceleration, and braking of the autonomous vehicle.

7. The method of claim 1 , further including:

determining, by the autonomous vehicle control unit, whether in the autonomous driving mode, a follow-me mode in which the holographic image required for the driving control follows a position of the first occupant or a stationary mode in which the holographic image is fixed at a predetermined position in the autonomous vehicle, is selected.

8. The method of claim 7 , further including:

identifying, by the autonomous vehicle control unit, a position of the first occupant in the follow-me mode, and

moving, by the autonomous vehicle control unit, an image of a brake button in accordance with the gesture of the first occupant, wherein the holographic image required for the driving control includes the image of the brake button.

9. The method of claim 7 , further including:

identifying, by the autonomous vehicle control unit, a position of the first occupant in the stationary mode; and

fixing, by the autonomous vehicle control unit, an image of a brake button at a predetermined position,

wherein the holographic image required for the driving control includes the image of the brake button.

10. The method of claim 7 , further including:

determining, by the autonomous vehicle control unit, whether the first occupant has selected an image of a brake button; and

displaying, by the autonomous vehicle control unit, an amount to which the brake button is pushed in a holographic image indicating the amount to which the brake button is pushed, when the brake button is selected,

wherein the holographic image required for the driving control includes the image of the brake button.

11. The method of claim 1 , further including:

performing, by the autonomous vehicle control unit in the autonomous driving mode, braking control or adjustment of vehicle speed in accordance with a magnitude of a request for braking of the autonomous vehicle.

12. The method of claim 11 , further including:

tightening, by the autonomous vehicle control unit in the autonomous driving mode, a safety belt for the first occupant when all occupants are seated in the autonomous vehicle and the request for braking is greater than a first threshold.

13. The method of claim 12 ,

wherein when the request for braking is smaller than a second threshold, the autonomous driving control unit adjusts the vehicle speed in accordance with the request for braking, and wherein the second threshold is smaller than the first threshold.

14. The method of claim 11 , further including:

outputting, by the autonomous vehicle control unit in the autonomous driving mode, a warning signal when a predetermined number of all occupants are not seated in the autonomous vehicle and the request for braking is greater than a second threshold.

15. The method of claim 14 , wherein when the request for braking is smaller than the second threshold, the autonomous driving control unit adjusts the vehicle speed in accordance with the request for braking.

16. The method of claim 11 , further including:

outputting, by the autonomous vehicle control unit in the autonomous driving mode, a warning signal when a predetermined number of all occupants are not seated in the autonomous vehicle and the request for braking is greater than a second threshold.

17. The method of claim 1 , wherein the autonomous vehicle control unit includes:

a processor; and

a non-transitory storage medium on which a program for performing the method of claim 1 is recorded and executed by the processor.

18. A non-transitory computer readable storage medium storing a program for performing the method of claim 1 and executed by a processor.
