摘要
针对城市道路环境中驾驶人的应激响应感知-制动反应时间特性,基于虚拟现实技术搭建了测试平台,对多名驾驶人在不同应激场景下的感知-制动反应时间进行了研究。结果表明,熟练驾驶人的感知-制动反应时间要略长于非熟练驾驶人,而青年驾驶人的感知-制动反应能力最为稳定。以驾驶经验、驾驶人年龄和车速为自变量的预测模型能够对驾驶人的应激感知-制动时间进行准确的预测。
Aiming at the driver＇ s perception-brake reaction time under urban road environment, test platform based on virtual reality technology was established, and driver＇ s stress perception time in different scene was ana- lyzed. The result shows that experienced driver＇ s perception-brake time was longer than the non-experienced drivers. The young driver＇ s perception-brake time was most stable. The forecast model which was established by using driver＇ s experience, driver＇ s age and vehicle speed can realize accurate prediction for driver＇ s perception-brake time.
