The invention provides a safe driving behavior evaluation method and system, and the method comprises a driver information obtaining step: enabling a face recognition function after a driver gets on avehicle, and judging the ID of the driver to obtain the driver information; a score calculation step: enabling the OBU to acquire driving behavior information of the driver within a preset time duration before from the cloud, acquire vehicle state information of the vehicle from the cloud, and calculate a current safe driving behavior score; a driving score broadcasting step: enabling the OBU ofthe vehicle to send a broadcast to the RSU through the v2x module, and broadcast the safe driving score of the vehicle; and an information broadcasting step: enabling the road side unit RSU to send abroadcast to a nearby OBU, and inform other vehicles except the vehicle of the safe driving score of the vehicle. When the automobile runs on the road, the method can predict the front or rear comingautomobile information, plan reasonable driving behaviors in advance, and avoid traffic accidents.
本发明提供了一种安全驾驶行为评估方法及系统,包括:驾驶员信息获取步骤:当有驾驶员上车后,开启面部识别功能,判断驾驶员ID获取驾驶员信息;评分计算步骤:车载单元OBU从云端获取驾驶员之前预设时间长度内的驾驶行为信息,从云端获取本车辆的车辆状态信息,计算出当前安全驾驶行为评分;驾驶评分播报步骤:本车辆的车载单元OBU通过v2x模块向路侧单元RSU发送广播,播报本车辆的安全驾驶评分;信息广播步骤:路侧单元RSU向附近存在的车载单元OBU发送广播,将本车辆的安全驾驶评分告知本车辆以外的其他车辆。汽车在路上行驶时,本发明可以预知前方或后方来车信息,提前规划合理驾驶行为,规避车祸的发生。
