摘要
基于60 689 km车辆运行数据提取了1 613个跟车行为片段,并分析了前向避撞预警(FCW)系统对跟车行为2个重要参数——车头时距和反应时间的影响.结果表明,FCW系统对跟车车头时距影响不显著,但显著降低了跟车中的反应时间.白天状态下,反应时间减少了0.13 s;后车逼近前车时,反应时间减少了0.09 s.
From 60 689 km of naturalistic driving data, 1 613 car-following events were identified. Two major parameters of car-following behavior were analyzed--time headway and reaction time. The results show that forward collision warning（FCW） did not have a significant effect on time headway; while FCW resulted in a 0.13 s decrease of reaction time in daytime driving, and a 0. 09 s decrease when a following vehicle had higher speed than the lead vehicle.
