Description

[0001] The present invention relates to a safe driving performance evaluation system for an aged driver,

The present invention relates to a system for assessing the safety driving performance of an elderly driver, and more particularly, to a system and a method for evaluating the accuracy and reliability of the elder driver's driving ability evaluation, And more particularly, to an aging driver's safe driving ability evaluation system for efficiently preventing traffic accidents caused by the above-mentioned problems.

As the transportation infrastructure has expanded and the automobile industry has developed, the number of vehicles has increased exponentially. As a result of this increase in the number of vehicles, driving licenses are recognized as qualifications acquired in the modern society.

Especially in recent years, as the aging society has increased due to an increase in the average life expectancy, the number of elderly drivers who are non-disease drivers who are general aged drivers belonging to high-risk traffic accidents and elderly drivers who have a history of cerebral diseases such as strokes, Respectively.

Generally, older drivers have lower body and cognitive functions compared to non-older drivers, which causes a significant increase in mortality rate in the event of a traffic accident compared to non-aged drivers.

In order to solve these problems, the road traffic corporation under the National Police Agency is using the CPAD (Cognitive Perceptual Assessment for Driving), which is a driving cognitive assessment tool, for the disabled driver or driver's license acquisition / Evaluation is carried out.

In general, CPAD is a driving perception evaluation tool that evaluates the driving ability of a person with brain damage impairment. It includes a depth perception, a sustained attention test, a divided attention, a stroop, There are 8 items in the test, such as digit span, field dependency, trail making test A, and trail making test B. However, This is because the system is composed of simple irritation and reaction that does not reflect the function, so it is not related to the actual driving ability and the efficiency of the driving ability evaluation is remarkably low. In addition, the evaluation is performed by a simple reaction using a separate keyboard Therefore, the accuracy and reliability of the evaluation are deteriorated.

[0004] In a driving performance evaluation system (hereinafter referred to as " prior art ") for evaluating the suitability of a driver who rides on a simulator to perform a simulated operation, the Korean Patent Registration No. 10-1432067 The conventional art requires a complicated and various simulator such as a steering wheel, a steering sensor, a shift lever, a speed change sensor, an accelerator pedal, an acceleration sensor, a brake pedal and a braking sensor, At the same time, the evaluator has a restriction that evaluation can be performed only when the evaluator moves to a place where the simulator is provided.
