%X 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.</br>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. Key words： forward collision warning(FCW); naturalistic driving study; car following behavior; headway time; reaction tim
