摘　　要：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。To explore ACC＇s impact on driving safety, actual road driving tests were carried out, Chinese typical road scenes were acquired, then these scenes were rebuilt in a driving simulator. Driving tests were made on a driving simulator under with/without ACC conditions, so as to contrastively analyze ACC＇s performance, and detect drivers ＇ emergency reaction, by analyzing TTC of drivers belonging different characteristic groups. The results show that ACC can handle most types of road situations, that when faced with dangerous situations that ACC can＇t handle, all kinds of drivers＇ emergency reaction with ACC driving is slower than that in manual driving, that female, old drivers or drivers with little ACC knowledge are more vulnerable to ACC＇s adverse impact, and that safety of ACC driving is dependent on driver＇s ACC knowledge.

关 键 词：自适应巡航控制(ACC)系统 驾驶安全性 模拟驾驶 碰撞时间(TTC) 驾驶人特征
