Fatigue driving prevention facility effectiveness test method and system

Abstract

The invention provides a fatigue driving prevention facility effectiveness test method and system and relates to the technical field of fatigue driving prevention. The method comprises the following steps: S1, obtaining vehicle data and driver electrocardiogram data based on a driving simulation experiment; S2, confirming that a driver enters a fatigue driving state before entering a fatigue driving prevention facility according to the electrocardiogram data; S3, intercepting vehicle data of the driver from the entry of the fatigue driving prevention facility to the test end, and respectivelycalculating data mean value of vehicle features; and S4, substituting the mean value of the vehicle feature data into an entropy weight-based advantage and disadvantage solution distance method to complete a utility test of a fatigue driving prevention facility. Compared with a real road test and a traditional driving fatigue simulation test, the fatigue driving prevention facility effectiveness test method and system provided by the invention not only can effectively reduce the safety risk and the test cost in the test process, but also can efficiently, comprehensively and environmentally test the effectiveness of different fatigue prevention facilities.

Description

technical field [0001] The invention relates to the technical field of fatigue driving prevention, in particular to a method and system for testing the effectiveness of fatigue driving prevention facilities. Background technique [0002] At present, the utility test of road facilities mainly adopts the method of actual road test. For example: in order to effectively reduce the traffic accident rate in the Zhongnanshan Highway Extra Long Tunnel (total length 18km) and alleviate driving fatigue in the tunnel, based on the analysis of the distribution characteristics and causes of traffic accidents in the tunnel, based on visual induction technology, road surface processing technology and excessive light Technology respectively designed the reference column, colored non-slip pavement and artificial landscape belt. The effectiveness of the three facilities is verified by setting three facilities in the tunnel and based on the change value of the actual traffic accident rate bef...

AI Technical Summary

Problems solved by technology

[0004] 1) The cost of field testing is high and it is difficult to change facilities later

Corresponding facilities need to be set up on the road section before the actual road test, and the cost of setting up the facilities and testing is high. If the anti-fatigue facilities do not achieve the expected effect after the test, the change of facilities will waste manpower and material resources

[0005] 2) The efficiency of real road testing is low

Only the facilities that have been set can be tested, but not all expected facilities can be tested, and the test cycle is long and the efficiency is low

[0006] 3) The road test has a high safety risk

In order to test the anti-fatigue effect of driving fatigue prevention facilities, the driver should enter the driving fatigue state before passing the corresponding facilities. If the driver enters the fatigue state during the actual road test, not only cannot guarantee the driving safety of himself, but also threaten the safety of other vehicles. Safe, easy to cause traffic accidents

[0007] 4) The real road test is greatly affected by external factors, and the accuracy of the experimental data cannot be guaranteed

During the actual road test, the consistency of the road conditions of the tested road sections cannot be guaranteed, and at the same time, it is greatly affected by the weather

[0008] 5) Relevant indicator data cannot be fully obtained during the road test

During the road test, it is relatively easy to obtain data such as vehicle speed and time. With the help of external instruments, data such as ECG, EEG, and eye movement can also be obtained. However, it is difficult to obtain the steering wheel angle and lane due to the impact of testing equipment and experimental costs. Offset and other indicators that can accurately reflect the driver's fatigue state

[0009] 6) The existing driving fatigue simulation test only focuses on the detection of driver fatigue state, and less attention is paid to the detection method of the effect of driving fatigue prevention facilities

[0010] To sum up, the actual road test has disadvantages such as high cost, low efficiency, high safety risk, great influence by external factors, and inability to fully obtain relevant index data. At the same time, the traditional driving simulation test does not involve the detection method of the effect of driving fatigue prevention facilities.

Although driving simulation technology has been widely used, the research on driving fatigue mainly focuses on the detection of driver fatigue state, and there is no attention to the impact of fatigue prevention facilities on drivers and the effectiveness of driving fatigue prevention facilities.
