Abstract

A vehicle includes a communication device configured to request a neighboring vehicle for first data related to autonomous driving of the neighboring vehicle and to receive the first data from the neighboring vehicle while the vehicle is driving; a sensor device configured to sense second data regarding a state of a user of the vehicle and to detect third data regarding driving information of the neighboring vehicle; and a controller configured to classify risks of the vehicle into classes according to a preset criterion based on the first data, the second data, and the third data, and to score the risks based on the classified classes.

First claim

What is claimed is:

1. A vehicle comprising;
a display;
a communication device configured to request a neighboring vehicle for first data related to an existence of autonomous driving of the neighboring vehicle and a plurality of advanced driver assistance systems (ADAS) of the neighboring vehicle and to receive the first data from the neighboring vehicle while the vehicle is driving;
a sensor device configured to sense second data regarding a state of a user of the vehicle and to detect third data regarding at least one of a relative velocity, a relative distance, and an expected driving path of the neighboring vehicle; and
a controller configured to obtain a first score for the first data, a second score for the second data, and a third score for the third data, respectively, sum the obtained first, second, and third scores, and control the display to display a danger zone based on the summed score,
wherein the first score is a score obtained by summing a score corresponding to a class of the autonomous driving of the neighboring vehicle, a score corresponding to whether or not the neighboring vehicle has a highway driving assistance function and the class of the autonomous driving of the neighboring vehicle, a score corresponding to a detection area of a lane keeping assistance function and the class of the autonomous driving of the neighboring vehicle, a score corresponding to the class of the autonomous driving of the neighboring vehicle and a degree of risk corresponding to the relative distance from the neighboring vehicle while performing the smart cruise function, and a score corresponding to the third data while performing an automatic emergency braking function, and
wherein the third score is a score obtained by summing a score corresponding to a degree of risk for the relative velocity, a score corresponding to the degree of risk for the relative distance, and a score corresponding to a degree of risk for the expected driving path of the neighboring vehicle.

2. The vehicle according to claim 1 , wherein the controller is further configured to give a warning to the user based on the second data.

3. The vehicle according to claim 1 , wherein the controller is further configured to compare the summed score with a preset value, and to determine a surrounding zone of the vehicle as one of a safety zone, a warning zone, or the danger zone based on a comparison between the summed score and the preset value.

4. The vehicle according to claim 3 , further comprising at least one of a steering device or an acceleration/deceleration device,
wherein the controller is configured to control at least one of the steering device or the acceleration/deceleration device such that the vehicle escapes from the danger zone based on a determination result whether the vehicle is in at least one of the safety zone, the warning zone, or the danger zone and based on the state of the user.

5. The vehicle according to claim 3 , further comprising:
a warning device configured to warn the user of the vehicle,
wherein the controller is configured to control the warning device to give a warning based on the summed score.

6. The vehicle according to claim 5 ,
wherein the controller is configured to control the display to display a guidance for the user to drive the vehicle to the safety zone based on the summed score.

7. A control method of a vehicle, comprising:
requesting a neighboring vehicle for first data related to an existence of autonomous driving of the neighboring vehicle and a plurality of advanced driver assistance systems (ADAS) of the neighboring vehicle, and receiving the first data from the neighboring vehicle;
detecting second data related to a state of a user of the vehicle and detecting third data about at least one of a relative velocity, a relative distance, and an expected driving path of the neighboring vehicle;
obtaining a first score for the first data, a second score for the second data, and a third score for the third data, respectively;
summing the obtained first, second, and third scores; and
controlling a display to display a danger zone based on the summed score,
wherein the obtaining the first score includes: obtaining by summing a score corresponding to a class of the autonomous driving of the neighboring vehicle, a score corresponding to whether or not the neighboring vehicle has a highway driving assistance function and the class of the autonomous driving of the neighboring vehicle, a score corresponding to a detection area of a lane keeping assistance function and the class of the autonomous driving of the neighboring vehicle, a score corresponding to the class of the autonomous driving of the neighboring vehicle and a degree of risk corresponding to the relative distance from the neighboring vehicle while performing the smart cruise function, and score corresponding to the third data while performing an automatic emergency braking function, and
wherein the obtaining the third score includes: obtaining by summing a score corresponding to a degree of risk for the relative velocity, a score corresponding to the degree of risk for the relative distance, and a score corresponding to a degree of risk for the expected driving path of the neighboring vehicle.

8. The method according to claim 7 , further comprising
warning the user based on the second data.

9. The method according to claim 7 , further comprising
comparing the summed score with a preset value, and determining a surrounding zone of the vehicle as a safety zone, a warning zone, or the danger zone based on a comparison between the summed score and the preset value.

10. The method according to claim 9 , further comprising
controlling the vehicle to escape from the danger zone based on a determination result from the determining whether the vehicle is in the safety zone, the warning zone, or the danger zone and based on the state of the user.

11. The method according to claim 9 , further comprising:
warning the user of the vehicle based on the risk; and
warning the user of the danger zone based on the summed score.

12. The method according to claim 11 , further comprising
displaying a guidance for the user of the vehicle to drive the vehicle to the safety zone based on the summed score.
