为探究自适应巡航控制(ACC)系统对驾驶安全性的影响,首先通过实际道路驾驶试验获取我国典型道路交通场景,用驾驶模拟器进行场景仿真,并在有/无ACC状态下开展模拟驾驶试验;然后分析ACC系统在中国典型道路中的表现,通过对比分析ACC模式下不同特征驾驶人的碰撞时间(TTC),探讨不同类型驾驶人的应急反应。结果表明,ACC能较好地处理大多数路况;但面对危险路况时,不管是哪种类型的驾驶人,ACC的应急反应都没有手动驾驶迅速;且女性、年老和对ACC认知度低的驾驶人更容易受ACC的不良影响;驾驶人对ACC的认知度决定其ACC驾驶的安全性。
In order to explore the impact of adaptive cruise control (ACC) on driving safety, a typical road traffic scenario in China was obtained through actual road driving test, a scene simulation was conducted with a driving simulator, and a simulated driving test was conducted with / without ACC Then, the performance of ACC system in typical roads in China was analyzed. By comparing and analyzing the TTC of different characteristic drivers in ACC mode, the emergency response of different types of drivers was discussed. The results showed that ACC was able to handle most of the traffic well; however, the ACC’s emergency response was not driven by hand quickly in the face of dangerous road conditions, regardless of the type of driver; and women, old age, and awareness of ACC Low drivers are more likely to be adversely affected by ACC; driver awareness of ACC determines the safety of their ACC driving.
