Abstract

An apparatus for evaluating driving safety comprises: a task/action storing unit that stores a task list and an action list, wherein the task list comprises at least one task that a driver can perform while driving and the action list comprises at least one action for performing the at least one task, a task/action defining unit that extracts a performing task that the driver currently intends from the task list and defines detailed actions for performing the performing task from the action list, a driving conduct analyzing unit that analyzes driving conduct on the basis of the performing task and the detailed actions and a driving safety evaluating unit that evaluates the degree of safe driving of the driver by using a result analyzed by the driving conduct analyzing unit.

Claims

1. An apparatus for evaluating a driving safety, comprising:

a task/action storing unit that stores a task list and an action list, wherein the task list comprises at least one task that a driver can perform while driving and the action list comprises at least one action for performing the at least one task;

a task/action defining unit that extracts a performing task that the driver currently intends from the task list and defines detailed actions for performing the performing task from the action list;

a driving conduct analyzing unit that analyzes driving conduct on the basis of the performing task and the detailed actions; and

a driving safety evaluating unit that evaluates the degree of safe driving of the driver by using a result analyzed by the driving conduct analyzing unit.

2. The apparatus of claim 1, wherein the action list further comprises information on an average time taken to perform each action.

3. The apparatus of claim 2, wherein the driving conduct analyzing unit analyzes the driving conduct by measuring the time taken for the driver to perform the performing task.

4. The apparatus of claim 3, wherein the driving safety evaluating unit evaluates the degree of the safe driving by comparing the average time for the detailed actions with the time taken for the driver to perform the performing tasks.

5. The apparatus of claim 3, wherein the driving safety evaluating unit calculates an estimated time taken to perform the performing task by using information on the average time, and evaluates the degree of safe driving by comparing the estimated time with the time taken for the driver to perform the performing task.

6. The apparatus of claim 5, wherein

the action list further comprises information on a weight value for each action, and

the driving safety evaluating unit evaluates the degree of safe driving in consideration of the weight value for each action.

7. A method of evaluating a driving safety, comprising:

defining a performing task that a driver currently intends and detailed actions for the performing task;

analyzing driving conduct on the basis of the performing task and the detailed actions; and

determining the degree of safe driving by using the analyzed result.

8. The method of claim 7, wherein the analyzing of the driving conduct comprises measuring a time taken for the driver to perform the performing task.

9. The method of claim 8, wherein the determining of the degree of safe driving includes comparing an average time for the detailed actions with the time taken for the driver to perform the performing task.

10. The method of claim 8, wherein the determining of the degree of safe driving includes calculating an estimated time taken to perform the performing task by use of the average time for the detailed actions, and determining the degree of safe driving by comparing the estimated time with the time taken for the driver to perform the performing task.
