Abstract
A vehicle control system includes a controller configured to determine whether a vehicle is operating in an autonomous driving mode or in a manual driving mode; and a steering device for adjusting a position of a wheel of the vehicle when the vehicle is operating in the manual driving mode. The steering device includes a knob configured to rotate about a rotation axis; a shaft connected to the knob, the shaft rotating about the rotation axis together with the knob by a rotational force transmitted from the knob; and an elastic part coupled to the shaft. In particular, when the shaft rotates from a reference position by the rotational force, the elastic part is compressed, and when the rotational force is removed, the elastic part is relaxed to return the shaft to the reference position.
Claims18
A vehicle control system having an autonomous driving system, comprising:
- a controller configured to determine whether a vehicle is operating in an autonomous driving mode or in a manual driving mode;
- and
- a steering device for adjusting a position of wheels of the vehicle when the vehicle is operating in the manual driving mode,
- wherein the steering device comprises:
- a knob configured to rotate about a rotation axis;
- a shaft connected to the knob, such that the shaft rotates about the rotation axis with the knob by a rotational force transmitted from the knob;
- and
- an elastic part coupled to the shaft,
- wherein in response to the shaft being rotated from a reference position by the rotational force, the elastic part is compressed, and in response to the rotational force being removed, the elastic part causes the shaft to rotate and return to the reference position, thereby causing the position of the wheels of the vehicle to be centered.

A vehicle control system comprising:
- a controller configured to determine whether a vehicle is operating in an autonomous driving mode or in a manual driving mode;
- and
- a steering device for adjusting a position of wheels of the vehicle when the vehicle is operating in the manual driving mode, wherein the steering device comprises:
- a knob configured to be rotated about a rotation axis;
- a shaft connected to the knob, such that the shaft is rotated about the rotation axis with the knob by a rotational force transmitted from the knob;
- an elastic part coupled to the shaft, wherein the elastic part comprises a torsional spring having a first end and a second end;
- a rotating body coupled to the shaft and configured to be rotated about the rotation axis with the shaft;
- a moving part formed on the rotating body to move the first end or the second end of the elastic part based on a rotation of the rotating body;
- and
- a first stopper disposed between the first end and the second end of the elastic part to support one of the first end or the second end when another of the first end or the second end is moved by the moving part,
- wherein, in response to the shaft being rotated in a counterclockwise direction away from a reference position by the rotational force, the second end of the elastic part is supported by the first stopper, and the first end of the elastic part is rotated in the counterclockwise direction by the moving part, thereby compressing the elastic part,
- wherein, in response to the rotational force being removed in a state in which the shaft is rotated in the counterclockwise direction, the first end of the elastic part rotates the moving part in a clockwise direction, thereby returning the shaft to the reference position,
- wherein, in response to the shaft being rotated in the clockwise direction away from the reference position by the rotational force, the first end of the elastic part is supported by the first stopper, and the second end of the elastic part is rotated in the clockwise direction by the moving part, thereby compressing the elastic part, and
- wherein, in response to the rotational force being removed in a state in which the shaft is rotated in the clockwise direction, the second end of the elastic part rotates the moving part in the counterclockwise direction, thereby returning the shaft to the reference position.

A vehicle control system comprising:
- a controller configured to determine whether a vehicle is operating in an autonomous driving mode or in a manual driving mode;
- and
- a steering device for adjusting a position of wheels of the vehicle when the vehicle is operating in the manual driving mode, wherein the steering device comprises:
- a knob configured to be rotated about a rotation axis;
- a shaft connected to the knob, such that the shaft is rotated about the rotation axis with the knob by a rotational force transmitted from the knob;
- an elastic part coupled to the shaft;
- a rotating body coupled to the shaft and configured to be rotated about the rotation axis with the shaft, wherein the rotating body includes gear teeth on at least a portion of an outer circumference thereof;
- and
- a damper disposed to be gear-meshed with the gear teeth of the rotating body, wherein the damper is rotated based on a rotation of the rotating body and generates a rotational resistance force during rotation,
- wherein in response to the shaft being rotated from a reference position by the rotational force, the elastic part is compressed, and in response to the rotational force being removed, the elastic part causes the shaft to rotate and return to the reference position while the damper exerts the rotational resistance force.
