The invention discloses an information aided driving method based on a cooperative vehicle infrastructure technology, which is characterized in that a following driving aided module considers the problem that a traditional intelligent vehicle can only refer to driving information of a single vehicle in front during following driving, and acquires behavior information of multiple vehicles in front by subscribing detection information of a publisher; and according to the information, an auxiliary car following behavior is carried out. According to the lane changing decision information auxiliary system, the problem that traffic accidents are easily induced by detection blind areas of a traditional vehicle is considered, and through real-time detection of a roadbed traffic unit, lane changing behavior decision is made based on a fuzzy rule in combination with information such as vehicle collision time, time headway and road conditions. When the vehicle has a fault and a lane changing behavior, a roadbed traffic unit and other traffic participants can be informed through message queue telemetry transmission (MQTT). Through MQTT-based road condition information assistance, the safety of the following and lane changing behaviors of the intelligent vehicle is effectively improved, and the probability of road traffic accidents caused by detection blind areas of the intelligent vehicle is reduced.
本发明公开了一种基于车路协同技术的信息辅助驾驶方法,跟驰驾驶辅助模块考虑了传统智能车辆在跟驰行驶中只能参考前方单个车辆驾驶信息的问题,通过订阅发布者的检测信息,获取前方多车行为信息,并根据该信息来进行辅助跟驰行为。换道决策信息辅助系统则是考虑了传统车辆由于检测盲区易诱发交通事故的问题,通过路基交通单元的实时检测,结合车辆碰撞时间、车头时距、道路路况等信息基于模糊规则进行换道行为的决策。当车辆出现故障、换道行为时,也可以通过消息队列遥测传输(MQTT)来告知路基交通单元及其他交通参与者。通过基于MQTT的路况信息辅助,有效提高智能车辆跟驰、换道行为的安全性,降低智能车辆由于检测盲区所诱发道路交通事故的概率。
