The invention provides a hybrid traffic system attack detection and optimization control method based on vehicle-road cooperation. The method comprises the following steps: a road side unit obtains motion information of a vehicle running on a target road through a network connection technology; according to the historical trusted motion information of the running vehicle and the trusted motion information of vehicles around the running vehicle, motion prediction information of the running vehicle is generated through a self-updating distributed estimator of a road side unit; constructing a composite attack detector of a road side unit according to the motion prediction information of the driving vehicle and a preset vehicle motion model, and dividing the motion information of the driving vehicle into abnormal data and non-abnormal data through the composite attack detector; according to the abnormal data and the non-abnormal data, generating an attack detection decision through a road side unit, and broadcasting trustable vehicle information and attack mark information of the driving vehicle; and according to the trusted vehicle information and the attack mark information of the driving vehicle, the intelligent network connection vehicle dynamically optimizes the vehicle control strategy of the intelligent network connection vehicle.

    本发明提供了一种基于车路协同的混合交通系统攻击检测与优化控制方法。该方法包括:路侧单元通过网联技术获取目标道路上行驶车辆的运动信息;根据行驶车辆的历史可信任运动信息和行驶车辆的周围车辆的可信任运动信息,通过路侧单元的自更新分布式估计器生成行驶车辆的运动预测信息;根据行驶车辆的运动预测信息和预设的车辆运动模型构建路侧单元的复合攻击检测器,并通过复合攻击检测器将行驶车辆的运动信息划分为异常数据和非异常数据;根据异常数据和非异常数据,通过路侧单元生成攻击检测决策,并广播可信任的车辆信息和行驶车辆的攻击标志信息;根据可信任的车辆信息和行驶车辆的攻击标志信息,智能网联汽车动态优化自身的车辆控制策略。
