Abstract

A vehicle may include a communicator configured to receive driver state information from a surrounding vehicle, a detector configured to obtain driving information related to surrounding vehicle, a driving assistance module configured to control at least one of a driving speed or a driving direction and a controller configured to determine whether a driver of the surrounding vehicle is in drowsiness state based on whether the received driver state information satisfies a predetermined condition and if the driver of the surrounding vehicle is determined as drowsiness state, control the driving assistance module to avoid the surrounding vehicle.

First claim

What is claimed is:

1. A vehicle comprising:
a communicator configured to receive driver state information from a surrounding vehicle;
a detector configured to obtain driving information related to the surrounding vehicle;
a driving assistance module configured to control at least one of a driving speed or a driving direction of the vehicle; and
a controller connected to the communicator, the detector and the driving assistance module and configured to determine whether a driver of the surrounding vehicle is in drowsiness state based on when the received driver state information satisfies a predetermined condition and control the driving assistance module to avoid the surrounding vehicle when the driver of the surrounding vehicle is determined to be in the drowsiness state,
wherein the controller is configured to inform a user of a deflection direction of the surrounding vehicle, and
wherein the controller is configured to control the driving assistance module such that the driving direction is opposite to the deflection direction of the surrounding vehicle when a control command related to driving of the vehicle is not received from the user for a predetermined first reference time from a time when the user is informed of the deflection direction of the surrounding vehicle.

2. The vehicle according to claim 1 ,
wherein the controller is configured to determine that the driver of the surrounding vehicle is in the drowsiness state upon determining that the driver state information is continuously received for more than a predetermined time or received for more than a predetermined number of times for a predetermined unit time.

3. The vehicle according to claim 1 ,
wherein the controller is configured to determine whether the surrounding vehicle is deflected based on the driving information related to the surrounding vehicle when the driver of the surrounding vehicle is determined to be in the drowsiness state, and is configured to control the driving assistance module to avoid the surrounding vehicle based on a deflection of the surrounding vehicle.

4. The vehicle according to claim 3 ,
wherein the controller is configured to determine the deflection of the surrounding vehicle based on at least one of speed information related to the vehicle, speed information, distance information, and lane information related to the surrounding vehicle included in the driving information related to the surrounding vehicle.

5. The vehicle according to claim 3 ,
wherein the controller is configured to control the driving assistance module such that the driving direction is opposite to the deflection direction of the surrounding vehicle when the surrounding vehicle is determined to be deflected.

6. The vehicle according to claim 5 , further including:
a display; and
a speaker; and
wherein the controller connected to at least one of the display and the speaker is configured to control the display or the speaker to inform the user of the deflection direction of the surrounding vehicle.

7. The vehicle according to claim 6 ,
wherein the controller is configured to control the driving assistance module such that a distance from the surrounding vehicle to the vehicle becomes a predetermined maximum value when a driving lane of the vehicle is not changed for a predetermined second reference time from a time when the user is informed of the deflection direction of the surrounding vehicle.

8. The vehicle according to claim 3 ,
wherein the controller is configured to control the driving assistance module such that a distance from the surrounding vehicle to the vehicle becomes a predetermined maximum value based on a position of the surrounding vehicle when the surrounding vehicle is determined as being not deflected.

9. The vehicle according to claim 8 ,
wherein the controller is configured to control the driving assistance module to change a driving lane of the vehicle or requests the user to change the driving lane upon determining that the surrounding vehicle is a following vehicle and driving information related to the following vehicle satisfies a predetermined condition.

10. The vehicle according to claim 9 ,
wherein the controller is configured to control the driving assistance module such that the distance from the surrounding vehicle to the vehicle becomes the predetermined maximum value upon determining that the driving lane is not changed for a predetermined third reference time from a time that is requested to change the driving lane.

11. The vehicle according to claim 1 , further including:
a display; and
a speaker; and
wherein the controller connected to at least one of the display and the speaker is configured to control the display or the speaker to output alarm when the driver of the surrounding vehicle is determined to be in the drowsiness state.

12. The vehicle according to claim 1 ,
wherein the controller is configured to control the driving assistance module to avoid a following vehicle when a driver of a preceding vehicle and a driver of the following vehicle are determined to be in the drowsiness state.

13. A method of controlling a vehicle, the method comprising:
receiving, by a controller, driver state information from a surrounding vehicle;
obtaining, by the controller, driving information related to the surrounding vehicle;
determining, by the controller, whether a driver of the surrounding vehicle is in a drowsiness state based on whether the received driver state information satisfies a predetermined condition; and
controlling, by the controller, at least one of driving speed and driving direction of the vehicle to avoid the surrounding vehicle when the driver of the surrounding vehicle is determined to be in the drowsiness state,
wherein the controlling at least one of driving speed and driving direction of the vehicle to avoid the surrounding vehicle further includes:
informing a deflection direction of the surrounding vehicle; and
controlling the driving direction such that the driving direction is opposite to the deflection direction of the surrounding vehicle when a control command related to driving of the vehicle is not received from a user for a predetermined first reference time from a time when the user is informed of the deflection direction of the surrounding vehicle.

14. The method according to claim 13 , wherein the controlling at least one of driving speed and driving direction of the vehicle to avoid the surrounding vehicle includes:
determining whether the surrounding vehicle is deflected based on the driving information related to the surrounding vehicle when the driver of the surrounding vehicle is determined to be in the drowsiness state, and controlling at least one of the driving speed and the driving direction of the vehicle to avoid the surrounding vehicle based on a deflection of the surrounding vehicle.

15. The method according to claim 14 , wherein the controlling at least one of driving speed and driving direction of the vehicle to avoid the surrounding vehicle further includes:
controlling the driving direction such that the driving direction is opposite to the deflection direction of the surrounding vehicle when the surrounding vehicle is determined to be deflected.

16. The method according to claim 15 , wherein the controlling at least one of driving speed and driving direction of the vehicle to avoid the surrounding vehicle further includes:
controlling the driving assistance module such that a distance from the surrounding vehicle to the vehicle becomes a predetermined maximum value when a driving lane of the vehicle is
