不同警告方式下驾驶人应激反应能力模拟试验研究

Simulation test study on stress response ability of drivers under different warning modes

为研究在道路突发危险场景下先进驾驶辅助系统的不同警告方式对驾驶人应激反应能力的影响,利用自主开发的驾驶人应激反应能力测试软件,以计算机模拟与驾驶模拟器为试验平台,以实际驾驶视频为试验场景,选取操作准确率和反应时间为测试指标,分析不同警告方式下驾驶人的应激反应能力。研究结果表明:视觉警告可有效缩短应激反应时间;视听觉组合警告中,视觉警告占主导作用,听觉警告起辅助作用;在真实场景视频试验环境下,驾驶模拟器模拟试验的操作效果优于计算机模拟试验。

In order to study the influence of different warning modes by the advanced driver assistance system on the stress response ability of drivers under the road emergency scenes, by using the self-developed test software for the stress response ability of drivers, taking the computer simulation and driving simulator as the test platforms and the actual driving videos as the test scenes, the stress response ability of drivers under different warning modes were analyzed by selecting the operation accuracy and reaction time as the test indexes. The results showed that the visual warning could effectively shorten the stress response time. The visual warning played a dominant role in the visual-auditory combination warning, and the auditory warning played an auxiliary role. In the real video test environment, the operation effect of driving simulator test was better than that of computer simulation test.
