Abstract

An apparatus for managing control authority transition in a vehicle is provided. The apparatus includes a steering device, an acceleration device, a deceleration device, a sensor configured to sense information about a driver of the vehicle, and a control circuit electrically connected with the steering device, the acceleration device, the deceleration device, and the sensor. The control circuit is configured to obtain state information about the driver using the sensor when performing an autonomous control, to receive a control input by the driver to at least one of the steering device, the acceleration device, or the deceleration device, to determine whether to transfer a control authority based on the state information and a reliability of the control input, and to transfer the control authority to the driver when the control authority is determined to transfer.

Claims

1. An apparatus for managing control authority transition in a vehicle, the apparatus comprising:

a steering device;

an acceleration device;

a deceleration device;

a sensor configured to sense information about a driver of the vehicle; and

a control circuit configured to be electrically connected with the steering device, the acceleration device, the deceleration device, and the sensor,

wherein the control circuit is configured to;

obtain state information about the driver using the sensor when performing an autonomous control;

receive, from the driver, a control input to at least one of the steering device, the acceleration device, or the deceleration device;

determine whether to transfer a control authority based on the state information and a reliability of the control input; and

transfer, to the driver, the control authority, when it is determined to transfer the control authority.

2. The apparatus of claim 1, wherein the sensor comprises a camera, and

wherein the control circuit is configured to:

obtain the state information by analyzing an image of the driver that is obtained by the camera.

3. The apparatus of claim 1, wherein the state information comprises information regarding a sight of the driver and information regarding a seating of the driver.

4. The apparatus of claim 1, wherein the reliability of the control input comprises information regarding a probability of collision by the control input.

5. The apparatus of claim 1, wherein the control circuit is configured to:

calculate an expected path of the vehicle based on the control input; and

determine the probability of collision based on the expected path.

6. The apparatus of claim 1, wherein the control circuit is configured to:

not transfer the control authority when it is not possible to transfer the control authority.

7. The apparatus of claim 1, wherein the apparatus further comprises:

an input device configured to be electrically connected with the control circuit,

wherein the control circuit is configured to;

immediately transfer, to the driver, the control authority when an input to transfer the control authority is received via the input device.

8. The apparatus of claim 1, wherein the apparatus further comprises:

the input device configured to be electrically connected with the control circuit,

wherein the control circuit is configured to;

resume the autonomous control, after the control authority is transferred, when the control input of the driver is stopped or when an input for the autonomous control is received via the input device.

9. The apparatus of claim 1, wherein the control circuit is configured to:

transfer, to the driver, the control authority when pupils of the driver and the seating of the driver seating are detected and when there is no probability of collision by the control input.

10. The apparatus of claim 1, wherein the control circuit is configured to:

not transfer the control authority, when the pupils of the driver and the seating of the driver are detected and when there is the probability of collision by the control input.

11. The apparatus of claim 1, wherein the control circuit is configured to:

not transfer the control authority when the pupils of the driver are not detected.

12. The apparatus of claim 1, wherein the control circuit is configured to:

perform the autonomous control based on a predetermined minimum risk maneuver (MRM) when the seating of the driver seating not detected.

13. A method for managing control authority transition in a vehicle, the method comprising:

obtaining, with a control circuit, state information about a driver of the vehicle when performing an autonomous control;

receiving, with the control circuit, a control input by the driver to at least one of a steering device, an acceleration device, or a deceleration device, wherein the steering device, the acceleration device, and the deceleration device are included in the vehicle;

determining, with the control circuit, whether to transfer a control authority based on the state information and a reliability of the control input; and

when the control authority is determined to transfer, transferring, with the control circuit, the control authority to the driver.

14. The method of claim 13, wherein the state information comprises information regarding a sight of the driver and information regarding a seating of the driver.

15. The method of claim 13, wherein the reliability of the control input comprises information regarding a probability of collision by the control input.
