Autonomous driving vehicle
An autonomous driving vehicle is configured to enable mutual switching between an autonomous driving state and a manual driving state. The autonomous driving vehicle includes a steering wheel, and a controller configured to control mechanical linkage or electrical linkage between the steering wheel and a directional vehicle wheel so as to be cut off based on whether the autonomous driving vehicle is in the autonomous driving state or the manual driving state.
1. An autonomous driving vehicle configured to enable mutual switching between an autonomous driving state and a manual driving state, the vehicle comprising:
a steering wheel; and
a controller configured to control a mechanical linkage or an electrical linkage between the steering wheel and a directional vehicle wheel so as to be disengaged or engaged based on whether the autonomous driving vehicle is in the autonomous driving state or the manual driving state, respectively,
wherein the controller is configured to control the mechanical linkage or the electrical linkage between the steering wheel and the directional vehicle wheel so as to be disengaged when the autonomous driving vehicle is in the autonomous driving state, and
wherein the controller is configured to perform control to temporarily switch to the manual driving state when user input for lane change is received in the autonomous driving state.
2. The vehicle according to claim 1 , wherein the controller is configured to perform control to begin a preparation operation to prepare for autonomous driving when a prescribed event occurs in the manual driving state.
3. The vehicle according to claim 2 , wherein the prescribed event is user input for switching from the manual driving state to the autonomous driving state.
4. The vehicle according to claim 2 , further comprising an output unit,
wherein the controller is configured to control the output unit so as to output information regarding switching to autonomous driving when the preparation operation begins.
5. The vehicle according to claim 2 , wherein, when the preparation operation begins in the state in which the steering wheel is rotated, the controller is configured to control the mechanical linkage or the electrical linkage so as to be disengaged while maintaining the steering wheel in the rotated state.
6. The vehicle according to claim 5 , wherein the controller is configured to control the steering wheel so as to return to an original state from the rotated state after the mechanical linkage or the electrical linkage is disengaged.
7. The vehicle according to claim 1 , wherein the controller is configured to perform control to switch to the manual driving state when it is sensed that the steering wheel is being gripped in the autonomous driving state in the state in which the steering wheel and the directional vehicle wheel are not in an engaged state, thereby controlling the steering wheel and the directional vehicle wheel so as to be mechanically or electrically linked to each other while maintaining the steering wheel and the directional vehicle wheel in the unengaged state.
8. The vehicle according to claim 7 , wherein the controller is configured to perform control to again switch to the autonomous driving state when the release of the grip of the steering wheel is sensed after switching to the manual driving state.
9. The vehicle according to claim 7 , wherein the controller is configured to perform control to begin an operation to prepare for autonomous driving when user input for switching to the autonomous driving state is received in the state in which the release of the grip of the steering wheel is sensed after switching to the manual driving state.
10. The vehicle according to claim 1 , wherein the controller is configured to control the steering wheel and the directional vehicle wheel so as to be mechanically or electrically linked to each other while the autonomous driving vehicle is in the manual driving state.
11. The vehicle according to claim 10 , wherein the controller is configured to perform control to begin a preparation operation to prepare for manual driving when a prescribed event occurs in the autonomous driving state.
12. The vehicle according to claim 11 , wherein the prescribed event is user input for switching from the autonomous driving state to the manual driving state, or an input corresponding to rotation of the steering wheel.
13. The vehicle according to claim 11 , further comprising an output unit,
wherein the controller is configured to control the output unit so as to output information regarding switching to manual driving when the preparation operation begins.
14. The vehicle according to claim 11 , wherein the controller is configured to control the steering wheel and the directional vehicle wheel so as to be mechanically or electrically linked to each other for engagement therebetween when the preparation operation begins.
15. The vehicle according to claim 14 , wherein the controller is configured to control the steering wheel and the directional vehicle wheel so as to be engaged with each other by rotating the steering wheel to correspond to a direction of the directional vehicle wheel.
16. The vehicle according to claim 15 , wherein the controller is configured to adjust a rotational speed of the steering wheel based on whether it is sensed that the steering wheel is being gripped.
17. The vehicle according to claim 15 , further comprising an output unit,
wherein the controller is configured to control the output unit so as to output information regarding an engagement state of the steering wheel and the directional vehicle wheel.
18. The vehicle according to claim 10 , wherein the controller is configured to control the mechanical linkage or the electrical linkage between the steering wheel and the directional vehicle wheel so as to be disengaged when an extent of direction change of the directional vehicle wheel per unit time is equal to a reference value or more in the manual driving state.
