摘要
随着我国汽车保有总量的不断增长,交通驾驶环境的安全问题日益凸显。交通驾驶环境是一个由驾驶员、车辆和道路共同参与组成的封闭系统,通过分析近年来我国交通事故发生的主要原因,驾驶员的驾驶行为已经成为危害交通环境安全的最主要因素。驾驶员的驾驶负荷(通常驾驶负荷包括体力负荷和精神负荷,本文所讨论的驾驶负荷均指精神负荷,不考虑体力负荷)能直接影响其驾驶行为表现进而影响到交通环境的安全,因此人们对驾驶员驾驶负荷问题的研究日益密切。目前针对驾驶员驾驶负荷的评价方法主要有三种:主观打分评价方法、操纵绩效评价方法和心理生理评价方法。本文采用操纵绩效和生理心理两种评价方法,设计了包含次级任务在内的模拟器驾驶实验对驾驶员的驾驶负荷进行量化分析。主要探究了驾驶员在被施加次级任务的情况下,操纵绩效以及生理心理等各项特征指标值的变化情况。并结合驾驶员次级任务的执行情况,找到与驾驶员驾驶负荷最密切相关的特征指标。该特征指标能够在一定程度上实现对驾驶负荷的量化评价,特征指标的大小能够反映驾驶员驾驶负荷的高低。
研究结果表明:紧急制动率(EBR)能有效地表征驾驶员的驾驶精神负荷。 [资料来源:http://www.doc163.com]

Abstract
With the continuous growth of the total car ownership in our country, the safety of driving environment has become increasingly prominent. The traffic environment is a driver, vehicle and road in closed system, analyses the main causes of traffic accident happened in our country in recent years, the driving behavior has become the main risk factors of traffic safety environment. The driver's driving load (usually driving load including physical load and mental load, driving load are discussed in this paper refers to the mental load, without considering the physical load) can affect the traffic environment directly affects the safety of the driver's driving behavior, so the research on the driver's driving load of people increasingly close. At present, there are three main evaluation methods for driver driving load: subjective scoring, evaluation method, manipulation performance evaluation method and psychological physiological evaluation method. In this paper, we use the two evaluation methods of manipulation performance and physiology and psychology, design the simulator driving experiment including secondary task, and quantify the driver's driving load. The paper mainly explores the changes of drivers' performance and physiological and psychological indexes in the case of secondary tasks.Combined with the implementation of the driver's secondary task, we find the characteristic indicators which are most closely related to the driver's driving load. The characteristic index can realize quantitative evaluation of driving load to a certain extent, and the size of characteristic index can reflect the driving load of driver. [版权所有:http://DOC163.com]
The results show that the emergency braking rate (EBR) can effectively characterize the driver's mental workload.
