Abstract

A method can include acquiring, by at least one controller, information on whether a state of an autonomous driving vehicle is switched from a manual driving state to an autonomous driving state; and controlling, by the at least one controller, directional vehicle wheels to change in direction regardless of a rotation of a steering wheel.

First claim

What is claimed is:

1. A control method of an electrical device for an autonomous driving vehicle configured to enable mutual switching between an autonomous driving state and a manual driving state, the method comprising:
acquiring, by at least one controller, information on whether a state of the autonomous driving vehicle is switched from the manual driving state to the autonomous driving state; and

controlling, by the at least one controller, directional vehicle wheels to change in direction regardless of a rotation of a steering wheel,
wherein the controlling the directional vehicle wheels to change in direction regardless of the rotation of the steering wheel comprises:
controlling a linkage between the steering wheel and the directional vehicle wheels to be disengaged.

2. The method of claim 1 , further comprising:
controlling, by the at least one controller, emission of light from a light emitting unit located on the steering wheel to correspond to change in the direction of the directional vehicle wheels.

3. The method of claim 1 , further comprising:
determining, by the at least one controller, whether the state of the autonomous driving vehicle is switched from the autonomous driving state to the manual driving state; and
controlling, by the at least one controller, the directional vehicle wheels to change in direction to correspond to the rotation of the steering wheel.

4. The method of claim 3 , wherein the controlling the directional vehicle wheels to change in direction to correspond to the rotation of the steering wheel comprises:
controlling the linkage between the steering wheel and the directional vehicle wheels to be engaged.

5. The method of claim 1 , further comprising:
performing, by the at least one controller, control to temporarily switch to the manual driving state when a user input for a lane change is received in the autonomous driving state.

6. A control method of an electrical device for an autonomous driving vehicle configured to enable mutual switching between an autonomous driving state and a manual driving state, the method comprising:
acquiring, by at least one controller, at least one signal corresponding to a user intent for switching from the autonomous driving state to the manual driving state while the autonomous driving vehicle is in the autonomous driving state; and
controlling, by the at least one controller, based on the at least one signal, a linkage between a steering wheel and a directional vehicle wheel to be linked to each other,
wherein the at least one signal is generated by at least one user input, corresponding to gripping the steering wheel, sensed by a sensor positioned at the steering wheel.

7. The method of claim 6 , wherein the controlling the linkage between a steering wheel and a directional vehicle wheel to be linked to each other comprises:
sensing, by the sensor, a grip pressure of the steering wheel, and
adjusting, by the at least one controller, a rotational speed of the steering wheel based on the sensed grip pressure.

8. The method of claim 6 , wherein the controlling the linkage between a steering wheel and a directional vehicle wheel to be linked to each other comprises:
rotating, by the at least one controller, the steering wheel by an angle corresponding to the direction of the directional vehicle wheels, when the autonomous driving vehicle drives along the curved road.

9. The method of claim 6 , further comprising:
acquiring, by the at least one controller, at least one signal corresponding to a user intent for switching from the manual driving state to the autonomous driving state while the autonomous driving vehicle is in the manual driving state; and
controlling, by the at least one controller, based on the at least one signal corresponding to the user intent for switching from the manual driving state to the autonomous driving state, the linkage between the steering wheel and the directional vehicle wheel to be disengaged.

10. An electrical device for an autonomous driving vehicle configured to enable mutual switching between an autonomous driving state and a manual driving state, the electrical device comprising:
at least one controller configured to:
acquire at least one signal corresponding to a user intent for switching from the autonomous driving state to the manual driving state while the autonomous driving vehicle is in the autonomous driving state; and
control, based on the at least one signal, a linkage between a steering wheel and a directional vehicle wheel to be linked to each other,
wherein the at least one signal is generated by at least one user input, corresponding to gripping the steering wheel, sensed by a sensor positioned at the steering wheel.
