The invention discloses an intelligent electric vehicle formation control method for defending denial of service network attack, and belongs to the field of automobile intelligent safety and automatic driving. For a vehicle formation control problem of DoS attack and external interference, a vehicle-mounted sensor and a V2X wireless communication system are utilized to realize information interaction between the vehicle and other vehicles, inverse model compensation and feedback linearization technologies are adopted, and a vehicle queue closed-loop control model with external interference is established. And designing a switching type queue robust control method for defending the DoS attack based on the observer model. A switching controller which only depends on relative output information for updating is designed for an electric vehicle longitudinal queue system, so that information transmission hidden dangers brought to the queue system by Dos attacks are effectively defended, external interference is suppressed, and performance indexes of formation control are realized. The stability of the queue system is achieved, and the expected vehicle-to-vehicle distance and the expected running speed of each vehicle in the queue are ensured.
一种防御拒绝服务网络攻击的智能电动车编队控制方法,属于汽车智能安全与自动驾驶领域。对于DoS攻击和外部干扰的车辆编队控制问题,利用车载传感器以及V2X无线通信系统来实现自身和其他车辆的信息交互,采取逆模型补偿和反馈线性化的技术,建立具有外部干扰的车辆队列闭环控制模型,设计一种基于观测器模型的防御DoS攻击的切换式队列鲁棒控制方法。针对电动车辆纵向队列系统设计出一种仅依赖相对输出信息进行更新的切换式控制器,进而有效防御Dos攻击给队列系统带来的信息传输隐患,同时抑制外部干扰,实现编队控制的性能指标。实现队列系统的稳定性,确保队列中每辆汽车的期望车车间距以及期望行驶速度。
