Driving assistance method based on vehicle-mounted ad hoc network

A driving assistance method based on a vehicle-mounted ad hoc network is characterized in that vehicles in a certain area detect road conditions, the road conditions are sent to surrounding vehicles through a VANET (vehicle-mounted ad hoc network), obtained road adhesion coefficients are updated to a cloud end, and the vehicles avoid or decelerate according to road information. Comprising the following steps: S1) acquiring a road adhesion coefficient; S2) transmitting road information; S3) calculating a safe distance; S4) warning by a vehicle-mounted terminal; 一种基于车载自组网的驾驶辅助方法，其中在一定区域内的车辆对道路情况进行检测，利用VANET(车载自组织网络)发送给周围车辆并将得到的路面附着系数更新至云端，车辆根据路面信息进行避让或减速。包括以下几个步骤：S1)获取路面附着系数S2)路面信息传输S3)计算安全距离S4)车载终端进行示警S5)若路面附着系数下降较大，则为根据云端路面数据为车辆重新规划路面较好的路径。
