【摘要】：隨著科技的進(jìn)步,汽車的普及程度越來越高,隨之而來的駕駛安全問題也在逐漸增多,汽車駕駛安全這一主題愈發(fā)成為人們關(guān)注的重點(diǎn)。在駕駛過程中,由于人因失誤導(dǎo)致的道路交通事故占了較大比例,因此越來越多的專家學(xué)者們致力于開發(fā)駕駛輔助系統(tǒng)來減少這一危險(xiǎn)性,平視顯示技術(shù)也是在該領(lǐng)域中應(yīng)運(yùn)而生的一項(xiàng)技術(shù)。本研究首先提出一種通過將預(yù)警圖形呈現(xiàn)在平視顯示系統(tǒng)上,進(jìn)而為駕駛員提供前方道路狀況預(yù)警這一預(yù)警顯示技術(shù),探索不同的預(yù)警信息呈現(xiàn)方式對(duì)于駕駛安全的影響,同時(shí)嘗試建立一套行之有效的的新型汽車預(yù)警體系。本研究包括兩部分,研究一為圖形預(yù)警平視顯示系統(tǒng)對(duì)模擬駕駛績(jī)效影響研究,其中首先進(jìn)行圖形預(yù)警模型的設(shè)計(jì)與優(yōu)化,通過問卷調(diào)查的形式進(jìn)行。首先根據(jù)駕駛過程中經(jīng)常遇到的危險(xiǎn)狀況,選取了8個(gè)對(duì)駕駛員危害較大的場(chǎng)景,在危險(xiǎn)場(chǎng)景圖形的設(shè)計(jì)過程中,選取了103名有駕駛經(jīng)驗(yàn)的被試對(duì)所設(shè)計(jì)的預(yù)警圖形進(jìn)行優(yōu)化,最終確定所采用的配色方案。實(shí)驗(yàn)一為圖形預(yù)警平視顯示系統(tǒng)對(duì)模擬駕駛績(jī)效影響研究。在實(shí)驗(yàn)室條件下通過模擬駕駛實(shí)驗(yàn),驗(yàn)證圖形預(yù)警能夠提升駕駛安全性。研究二為平視顯示下圖形預(yù)警對(duì)模擬駕駛的影響因素研究,由兩個(gè)實(shí)驗(yàn)組成:實(shí)驗(yàn)二探索在圖形預(yù)警條件下,不同預(yù)警圖形呈現(xiàn)時(shí)間對(duì)于駕駛績(jī)效的影響,探索圖形預(yù)警出現(xiàn)的最佳時(shí)間;實(shí)驗(yàn)三為比較預(yù)警信息不同呈現(xiàn)方式對(duì)于駕駛績(jī)效的影響,探究圖形預(yù)警、聲音預(yù)警、圖形聲音雙預(yù)警這三種預(yù)警條件下駕駛績(jī)效的差異。由實(shí)驗(yàn)結(jié)果得出以下結(jié)論:1、采用圖形預(yù)警系統(tǒng)條件下駕駛員的駕駛績(jī)效在碰撞次數(shù)、縱向加速度、油門釋放反應(yīng)時(shí)、剎車反應(yīng)時(shí)、約化速度、折合能量、轉(zhuǎn)向反應(yīng)時(shí)、平均反應(yīng)時(shí)和最快反應(yīng)時(shí)上的表現(xiàn)都顯著高于未采用圖形預(yù)警系統(tǒng)下的表現(xiàn);2、不同預(yù)警時(shí)間在縱向加速度、油門釋放反應(yīng)時(shí)、剎車反應(yīng)時(shí)、剎車至最大值時(shí)間、轉(zhuǎn)向反應(yīng)時(shí)和平均反應(yīng)時(shí)上均有顯著差異,其中當(dāng)預(yù)警圖形呈現(xiàn)時(shí)間為2秒或3秒呈現(xiàn)時(shí),駕駛員的駕駛績(jī)效表現(xiàn)最好;3、圖形預(yù)警、聲音預(yù)警以及圖形聲音雙預(yù)警這三種預(yù)警方式在縱向加速度、油門釋放反應(yīng)時(shí)和約化速度三個(gè)指標(biāo)下均有顯著差異,其中在縱向加速度指標(biāo)上圖形預(yù)警條件下駕駛員表現(xiàn)最好,在油門釋放反應(yīng)時(shí)指標(biāo)上聲音預(yù)警條件下駕駛員表現(xiàn)最好,在約化速度指標(biāo)上雙預(yù)警條件下駕駛員表現(xiàn)最好。本研究探索并建立了一套在平視顯示系統(tǒng)下的圖形預(yù)警系統(tǒng),采用圖形的形式將駕駛員在駕駛過程中即將遇到的危險(xiǎn)情況進(jìn)行呈現(xiàn),從而為駕駛員避免危險(xiǎn)提供輔助作用,并且在預(yù)警圖形呈現(xiàn)時(shí)間以及預(yù)警信息呈現(xiàn)方式上都做了探索研究,細(xì)化該預(yù)警模型的呈現(xiàn)條件與呈現(xiàn)方式,具有較高的應(yīng)用價(jià)值,為未來汽車預(yù)警系統(tǒng)的研發(fā)與制作提供一定的借鑒意義。
[Abstract]:With the development of science and technology, the popularity of automobile is becoming more and more high, and the problem of driving safety is also increasing. The theme of automobile driving safety has become the focus of attention. In the process of driving, more and more experts and scholars are devoting themselves to developing driving aid system to reduce the risk because of the large proportion of road traffic accidents caused by human error. Parallel view display technology is also a technology that arises at the historic moment in this field. In this study, we first put forward an early warning display technology, which can provide the driver with the warning technology of road condition in front of the display system, and explore the influence of different early warning information presentation methods on driving safety. At the same time, try to establish a set of effective new car warning system. This research includes two parts. The first part is the research on the effect of the graphics warning and display system on the driving performance. Firstly, the design and optimization of the graphical warning model are carried out by questionnaire. First of all, according to the dangerous situation often encountered in the driving process, 8 scenarios which are harmful to the driver are selected. In the design process of the dangerous scene graph, 103 subjects with driving experience are selected to optimize the designed warning pattern. Finally, the color matching scheme is determined. Experiment one is a study on the effect of graphical warning and level view display system on simulated driving performance. Under the condition of laboratory, simulation driving experiment is carried out to verify that graphical warning can improve driving safety. The second is the study of the influencing factors of graphic warning on driving simulation under the condition of visual display, which is composed of two experiments: experiment two explores the effect of different early warning graphics presentation time on driving performance under the condition of graphic warning. The third experiment is to compare the influence of different presentation ways of early warning information on driving performance, and explore the differences of driving performance under three warning conditions: graphics early warning, sound early warning and graphics and sound double warning. The following conclusions are drawn from the experimental results: 1. Under the condition of graphical early warning system, the driver's driving performance is reduced speed, reduced energy, steering reaction when the collision number, longitudinal acceleration, throttle release reaction, braking reaction, etc. The average response time and the fastest reaction time were significantly higher than those without the graphical early warning system. The braking time to the maximum at different warning times was longitudinal acceleration and throttle release reaction. There were significant differences between the steering response time and the average reaction time. When the display time of the warning pattern was 2 seconds or 3 seconds, the driver's driving performance was the best. There are significant differences in the longitudinal acceleration, throttle release reaction time and reduced speed between the three early warning methods, among which the driver is the best under the longitudinal acceleration index. Under the condition of sound warning on the target of throttle release reaction, the driver's performance is the best under the condition of double warning on the reduced speed index. This study explores and establishes a graphical early warning system based on the level view display system, which presents the dangerous situation that the driver is about to encounter in the driving process, thus providing the auxiliary role for the driver to avoid the danger. And in the early warning graph presentation time and the early warning information presentation way has done the exploration research, refines this early warning model to present the condition and the presentation way, has the higher application value, It can provide some reference for the research and manufacture of automobile early warning system in the future.
