驾驶模拟器运动系统对自由驾驶行为的影响分析

Effects of Motion System of Driving Simulator on Free Driving Behaviors

摘要:

通过构建晴、雾天气下自由驾驶两个实验场景，对比分析了8自由度和零自由度驾驶模拟器对自由驾驶加减速行为、期望速度等变量的影响.结果发现，当能见度相同时，驾驶模拟器运动系统自由度对加速行为和期望速度影响不显著，但对减速行为影响显著，特别是对浓雾天气下的减速行为影响显著；当驾驶模拟器运动系统自由度相同时，能见度对驾驶员的加减速行为和期望速度有显著影响.

Abstract:

The degree of freedom (DOF) of the motion system does influence driving behavior. This paper established two free driving scenarios under clear weather and foggy weather to investigate the impacts of 8 DOF and fixed based driving simulator on the driving behaviors of acceleration, deceleration and desired speed. The results show that the DOF of driving simulator has less impacts on the acceleration behavior and desired speed, yet it has significant impacts on the deceleration behavior, especially at foggy weather conditions. The visibility of weather conditions has significant impacts on the driving behaviors.
