摘　　要：为了求解冰雪路面安全车速,首先对冰雪路面进行分类,并构建各类冰雪路面数据集。在已有数据集的基础上进行深度学习,通过图像识别技术判断冰雪路面的类别。同时根据冰雪路面的分类与相应附着系数的映射关系,得到该冰雪路面的附着系数。接下来构建冰雪路面安全车速求解模型,模型综合考虑了车辆直行、转弯两种不同的运行状态。最后,将路面附着系数输入冰雪路面安全车速求解模型,得到该路段的安全车速。In order to solve the safe vehicle speed on icy and snowy road,the icy and snowy road is firstly categorized and various types of icy and snowy road datasets are constructed.Deep learning is carried out on the basis of the existing dataset,and the categories of icy and snowy road are judged by image recognition.At the same time,according to the mapping relationship between the categorization of the icy and snowy road surface and the corresponding adhesion coefficient,the adhesion coefficient is obtained.Next,the safe speed solving model is constructed for the icy and snowy road,and the model comprehensively considers two different states of the vehicle:going straight and turning.Finally,the adhesion coefficient is inputted into the safe vehicle speed solution model to obtain the safe vehicle speed of the road section.
