Vehicle and safe driving assistance method therefor
A vehicle includes a processing device that detects an authentication device approaching the vehicle, determines a user's impaired state based on user condition information acquired using at least one device mounted on the vehicle, and performs a safe driving assistance service. The safe driving assistance service can prevent an impaired user from operating the vehicle.
1. A vehicle, comprising:
a processing device configured to:
detect an authentication device approaching the vehicle,
determine whether a user is in a driving dangerous condition based on user condition information acquired using at least one device mounted on the vehicle,
calculate a guide pattern following matching degree of the user by emitting a guide pattern around the vehicle when it is determined that the user is in the driving dangerous condition,
determine a user's impaired state based on the guide pattern following matching degree, and
perform a safe driving assistance service.
2. The vehicle of claim 1 , wherein the user condition information includes at least one of walking information, speech information, driver monitoring information, or biometric information of a user.
3. The vehicle of claim 1 , wherein the processing device is configured to perform a main check for a user condition when it is determined that the user is impaired to safe driving.
4. The vehicle of claim 1 , wherein the processing device is configured to calculate a driving risk degree of the user based on weighting and scoring criteria for each information stored in storage when the guide pattern following matching degree is less than a reference value.
5. The vehicle of claim 4 , wherein the processing device is configured to update vehicle history and user history information based on the calculated driving risk degree when the driving risk degree is less than a first reference value.
6. The vehicle of claim 5 , wherein the processing device is configured to output a first-phase warning when the driving risk degree exceeds the first reference value and is less than a second reference value.
7. The vehicle of claim 6 , wherein the processing device is configured to additionally perform a user test when the driving risk degree exceeds the second reference value.
8. The vehicle of claim 7 , wherein the processing device is configured to output a second-phase warning when the user has not passed at least one item of test items included in the user test.
9. The vehicle of claim 8 , wherein the processing device is configured to identify a user's intention to start the vehicle and take a subsequent action when the user attempts to start the vehicle after output of the second-phase warning.
10. A safe driving assistance method for a vehicle, comprising:
detecting, by a processing device in the vehicle, an authentication device approaching the vehicle;
determining, by the processing device whether the user is in a driving dangerous condition base on user condition information acquired using at least one device mounted on the vehicle when the authentication device is detected;
calculating a guide pattern following matching degree of the user by emitting a guide pattern around the vehicle when it is determined that the user is in the driving dangerous condition;
determining, by the processing device, a user's impaired state based on the guide pattern following matching degree; and
performing, by the processing device, a safe driving assistance service.
11. The safe driving assistance method of claim 10 , wherein the user condition information includes at least one of walking information, speech information, driver monitoring information, or biometric information of the user.
12. The safe driving assistance method of claim 10 , further comprising: performing a main check for a user condition when it is determined that the user is impaired to safe driving.
13. The safe driving assistance method of claim 10 , wherein performing the safe driving assistance service includes calculating a driving risk degree of the user using the user condition information based on weighting and scoring criteria for each information stored in storage when the guide pattern following matching degree is less than a reference value.
14. The safe driving assistance method of claim 13 , wherein performing the safe driving assistance service includes:
determining whether the driving risk degree is less than or equal to the first reference value, and
updating vehicle history and user history information based on the calculated driving risk degree when the driving risk degree is less than the first reference value.
15. The safe driving assistance method of claim 14 , wherein performing the safe driving assistance service includes determining whether the driving risk degree exceeds the first reference value and is less than a second reference value when the driving risk degree is not less than the first reference value.
16. The safe driving assistance method of claim 15 , wherein performing the safe driving assistance service further includes outputting a first-phase warning when the driving risk degree exceeds the first reference value and is less than the second reference value.
17. The safe driving assistance method of claim 16 , wherein performing the safe driving assistance service further includes:
additionally performing a user test when the driving risk degree exceeds the second reference value, and
outputting a second-phase warning when the user has not passed at least one item of test items included in the user test.
18. The safe driving assistance method of claim 17 , further comprising:
identifying a user's intention to start the vehicle and take a subsequent action when the user attempts to start the vehicle after output of the second-phase warning.
