Abstract

A driving diagnosis method and driving diagnosis apparatus enable drivers to recognize where their own driving diagnosis result is located in the driving behavior distribution of a safe driver group and the driving behavior distribution of a dangerous driver group. The degree of a driver's dangerous driving behavior is set as a horizontal axis, the number of drivers according to the dangerous driving behavior degree is set as a vertical axis, and screen information including distributions of a safe driver group and a dangerous driver group as determined by using travel history information about the drivers stored in a storage unit, and a diagnosis result of the dangerous driving behavior of a diagnosis target driver is generated and output.

First claim

1 . A driving diagnosis method for having a computer set a degree of a driver's dangerous driving behavior as a horizontal axis and the number of drivers according to the dangerous driving behavior degree as a vertical axis and generate and output screen information including distribution of a safe driver group and a dangerous driver group as determined by using travel history information with regard to the drivers stored in a storage unit, and a diagnosis result of the dangerous driving behavior of a diagnosis target driver.

2 . The driving diagnosis method according to claim 1 , wherein the computer is made to determine an evaluation criterion for diagnosing driving of the diagnosis target driver based on the distribution.

3 . The driving diagnosis method according to claim 2 , wherein the computer is made to diagnose the dangerous driving behaviors of the diagnosis target driver by using the evaluation criterion.

4 . The driving diagnosis method according to claim 3 , wherein the computer is made to display, in the distribution, a score as the diagnosis result of the dangerous driving behavior of the diagnosis target driver.

5 . The driving diagnosis method according to claim 3 , wherein the computer is made to display, in the distribution, a plurality of diagnosis results of the diagnosis target driver in a chronological order.

6 . The driving diagnosis method according to claim 4 , wherein the computer is made to:
divide a plurality of drivers stored in the storage unit into a plurality of groups based on driver information including accident record of the plurality of drivers; extract two groups from the divided plurality of groups; calculate distributions of the dangerous driving behavior from the travel history information of the driver groups which are the extracted two groups; and diagnose, in case there is a significant difference between the calculated distributions, driving with respect to the dangerous driving behavior of the diagnosis target driver by using statistic information thereof and the travel history information of the diagnosis target driver.

7 . A driving diagnosis apparatus comprising:
a storage unit for storing travel history information of drivers; and a processor unit, wherein the processor unit sets a degree of a driver's dangerous driving behavior as a horizontal axis and the number of drivers according to the dangerous driving behavior degree as a vertical axis and generates and outputs screen information including distribution of a safe driver group and a dangerous driver group as determined by using travel history information about the drivers, and a diagnosis result of the dangerous driving behavior of a diagnosis target driver.

8 . The driving diagnosis apparatus according to claim 7 , wherein the processor unit determines an evaluation criterion for diagnosing driving of the diagnosis target driver based on the distribution.

9 . The driving diagnosis apparatus according to claim 8 , wherein the processor unit diagnoses the dangerous driving behaviors of the diagnosis target driver by using the evaluation criterion.

10 . The driving diagnosis apparatus according to claim 9 , wherein the processor unit displays a score as the diagnosis result of the dangerous driving behavior of the diagnosis target driver in the distribution.

11 . The driving diagnosis apparatus according to claim 9 , wherein the processor unit displays a plurality of diagnosis results of the diagnosis target driver in a chronological order in the distribution.

12 . The driving diagnosis apparatus according to claim 10 , wherein the processor unit:
divides a plurality of drivers stored in the storage unit into a plurality of groups based on driver information including accident record of the plurality of drivers; extracts two groups from the divided plurality of groups; calculates distributions of the dangerous driving behavior from the travel history information of the driver groups which are the extracted two groups; and diagnoses, if there is a significant difference between the calculated distributions, driving with respect to the dangerous driving behavior of the diagnosis target driver by using statistic information thereof and the travel history information of the diagnosis target driver.
