摘要
论文运用驾驶模拟舱研究饮酒对驾驶操作行为的影响.在由急弯、紧急停车港、障碍区和直线路段组成的虚拟场景中,利用驾驶模拟系统实时采集驾驶操作行为数据,建立各种操作行为的评价指标,运用成对t检验方法对各指标的实验数据进行分析.结果表明,饮酒对驾驶员的制动、转向、离合、油门等操作行为有显著影响,随着酒精的消散,松离合器踏板的速度、踩制动踏板和油门踏板的速度与深度等指标的差异逐渐减小.实验结果说明饮酒后驾驶员的操作行为发生了显著变化,且这种变化随酒精浓度的降低逐渐减小.该结论为进一步研究饮酒对驾驶操作影响的定量分析与判断奠定了基础.
This paper investigates how drinking affects driving operations with a simulation system.Under virtual scenes made of sharp curves,emergency stop belts,obstacle zones and straight line segments,the simulation system monitors and saves real-time data of driving operations.And the variables of all kinds of driving operations are set and analyzed.The simulation results show that the driving operations have significant changes after drinking by the paired sample t-test.The results indicate that drinking affects significantly the driving operations,such as braking,steering,releasing clutch and accelerating,and that the differences of driving operations between before drinking and after drinking reduces gradually including the speed of releasing clutch and the speed and depth of stepping brake-pedal and accelerator-pedal with the alcohol dissipating.The results show that driving operations have significant changes after drinking and these differences reduce gradually with the blood alcohol concentration dropping.The study provides a reference for further quantitative analysis of the effects of drinking on driving operations.
