摘 要: 驾驶员在驾驶过程中不可避免会接受二次任务,紧急工况下注意力的分散将危及生命安全。研究通过驾驶员手持电话与微信语音两种通信方式下的避撞反应能力实验,对驾驶员生理特性变化进行详细分析。8名测试者参与模拟器实验,限定时速保持在50~70 km/h. 实验所采集的心率、皮肤电信号和呼吸灯生理指标均可表征不同紧张程度下驾驶员的精神负荷状态。结果表明,两种接听方式工况下精神负荷上升,微信语音任务高于手机接听任务,各参数变化特征可为前方防碰撞系统参数修改提供一定的理论依据。

Abstract: Drivers in the process of driving will inevitably accept secondary task, and attention points of dispersion can lead drivers to an emergency condition which will endanger the safety of life. In this article, we carried on reflect ability with the drivers holding a phone and Wechat voice communication of emergency braking time under the condition of experiment and the change of drivers’ physiological characteristics were analyzed in detail. Eight subjects participated in the simulator test, with the qualified tests speed at 50-70 km/h. Experiments prove that the heart rate, skin electrical signals and respiratory physiology indexes under different stress levels can be characterized for drivers’ mental load state. The results show that mental load rises under two kinds of working conditions of answering task; mental load in Wechat voice communication task is higher than that in mobile phone answering task. Characteristics of various parameters provide certain theoretical basis for the parameter modifications of front collision system.
