Abstract

Driving support systems, methods, and programs detect an operation of a vehicle that is determined as dangerous driving, determine whether the detected operation is an avoidance operation to avoid a factor to be avoided in the vicinity of the vehicle, and obtain information related to an operation accompanying the detected operation when the detected operation is determined to be the avoidance operation. The systems, methods, and programs determine whether the detected operation is an appropriate avoidance operation based on the obtained information, and determine that the detected operation is not dangerous driving when the detected operation is determined to be the appropriate avoidance operation.

Claims

1. A driving support system for a vehicle, comprising:

a controller that;

detects an operation of the vehicle that is determined as dangerous driving;

determines whether the detected operation is an avoidance operation to avoid a factor to be avoided in the vicinity of the vehicle;

obtains information related to an operation accompanying the detected operation when the detected operation is determined to be the avoidance operation;

determines whether the detected operation is an appropriate avoidance operation based on the obtained information; and

determines that the detected operation is not dangerous driving when the detected operation is determined to be the appropriate avoidance operation.

2. The driving support system according to claim 1, wherein:

the vehicle crossing a road marking line prohibiting deviation from a lane is determined to be a dangerous driving operation.

3. The driving support system according to claim 2, wherein:

the obtained information is information related to a traveling trace of the vehicle in a predetermined section before and after the detected operation is detected; and

the controller determines that the detected operation is the appropriate avoidance operation when the traveling trace matches a road shape of the predetermined section.

4. The driving support system according to claim 2, wherein:

the obtained information is information related to a direction indicator; and

the controller determines that the detected operation is the appropriate avoidance operation when the information related to the direction indicator indicates that the direction indicator is turned on.

5. The driving support system according to claim 2, wherein:

the obtained information is information related to a speed of the vehicle; and

the controller determines that the detected operation is the appropriate avoidance operation when a value indicated by the information related to the speed of the vehicle satisfies a predetermined reference.

6. The driving support system according to claim 5, wherein the controller:

calculates a speed reduction ratio based on the obtained information; and

determines that the detected operation is the appropriate avoidance operation when the speed reduction ratio is equal to a predetermined reference value or higher.

7. The driving support system according to claim 5, wherein the controller:

calculates a speed increase ratio based on the obtained information; and

determines that the detected operation is the appropriate avoidance operation when the speed increase ratio is equal to a predetermined reference value or higher.

8. A vehicle navigation device including the driving support system according to claim 1.

9. A driving support method for a vehicle, comprising:

detecting an operation of the vehicle that is determined as dangerous driving;

determining whether the detected operation is an avoidance operation to avoid a factor to be avoided in the vicinity of the vehicle;

obtaining information related to an operation accompanying the detected operation when the detected operation is determined to be the avoidance operation;

determining whether the detected operation is an appropriate avoidance operation based on the obtained information; and

determining that the detected operation is not dangerous driving when the detected operation is determined to be the appropriate avoidance operation.

10. The driving support method according to claim 9, wherein:

the vehicle crossing a road marking line prohibiting deviation from a lane is determined to be a dangerous driving operation.

11. The driving support method according to claim 10, wherein:

the obtained information is information related to a traveling trace of the vehicle in a predetermined section before and after the detected operation is detected; and

the method further comprises determining that the detected operation is the appropriate avoidance operation when the traveling trace matches a road shape of the predetermined section.

12. The driving support method according to claim 10, wherein:

the obtained information is information related to a direction indicator; and

the method further comprises determining that the detected operation is the appropriate avoidance operation when the information related to the direction indicator indicates that the direction indicator is turned on.

13. The driving support method according to claim 10, wherein:

the obtained information is information related to a speed of the vehicle; and

the method further comprises determining that the detected operation is the appropriate avoidance operation when a value indicated by the information related to the speed of the vehicle satisfies a predetermined reference.

14. The driving support method according to claim 13, further comprising:

calculating a speed reduction ratio based on the obtained information; and

determining that the detected operation is the appropriate avoidance operation when the speed reduction ratio is equal to a predetermined reference value or higher.

15. The driving support method according to claim 13, further comprising:

calculating a speed increase ratio based on the obtained information; and

determining that the detected operation is the appropriate avoidance operation when the speed increase ratio is equal to a predetermined reference value or higher.

16. The driving support method according to claim 9, wherein the steps of the method are implemented by a controller.

17. A computer-executable storage medium storing a computer-executable program usable for vehicle driving support, the program comprising:

instructions for detecting an operation of the vehicle that is determined as dangerous driving;

instructions for determining whether the detected operation is an avoidance operation to avoid a factor to be avoided in the vicinity of the vehicle;

instructions for obtaining information related to an operation accompanying the detected operation when the detected operation is determined to be the avoidance operation;

instructions for determining whether the detected operation is an appropriate avoidance operation based on the obtained information; and

instructions for determining that the detected operation is not dangerous driving when the detected operation is determined to be the appropriate avoidance operation.

18. The storage medium according to claim 17, wherein:

the vehicle crossing a road marking line prohibiting deviation from a lane is determined to be a dangerous driving operation.
