摘　　要：当发现车辆发生安全事故机率达到一定程度时,及时警示驾驶员采取恰当措施操纵车辆,可有效地减少交通事故的发生。通过对基于车路耦合的汽车山区行驶安全度模型的分析,确定了可用来预测车辆在山区道路行驶过程中安全程度的参数,同时提出山区道路车辆行驶安全预警系统设计方案。该系统可以根据测试车辆的某些运行状态参数,结合车辆前方道路参数计算车辆当前的安全度量化值及其变化趋势,预测车辆安全事故发生的可能性大小。When confronting with a certain level of risk of accident,an early-warning system can alert drivers for taking appropriate measures to reduce traffic accidents effectively.Through a safety model developed particularly for mountainous highways based on vehicle-road coordination,a set of safe parameters predicting vehicle safe degree are determined.Then,a design scheme of an early-warning system for vehicles traveling on the mountainous highways is proposed.The proposed system can predict the probability of traffic accident according to the vehicle＇s current safety degree and its changing trend calculated based on vehicle operational parameters and road parameters.
