摘要:
线控车辆信息安全是指电信号传输的转向指令免受威胁、干扰和破坏,近年来关于车辆信息安全的智能网联汽车受到黑客严重威胁,信息安全对线控车辆系统的安全起着决定性作用.鉴于此,针对线控车辆的信息安全问题提出一种基于事件触发策略的四轮线控车辆系统的预测控制方案,该方案利用事件触发控制对控制通道进行选择,根据李雅普诺夫稳定理论给定幂指数稳定的充分条件,进而设计事件触发条件,并结合模型预测控制对未来动态信息进行预测,能在潜在对手攻击的情况下,保证车辆安全行驶.仿真结果表明,所提出方案具有良好的抗干扰能力和抗黑客攻击能力.

Abstract:
Information security of the steer-by-wire vehicle means protecting the steering instructions of electrical signal transmission from threats, interference and destruction. In recent years, intelligent connected vehicles related to information security have been seriously threatened by hackers. Thus, information security is one of vital issues for steer-by-wire vehicle systems. This paper presents a tube model predictive control scheme for a 4-wheel steer-by-wire vehicle, in which the event-triggered strategy is adopted in order to prevent potential opponents from attacking and ensure the information security. This scheme uses event trigger control to select control channels, and provides sufficient conditions for power exponential stability according to the Lyapunov stability theory, then designs event trigger conditions. In addition, the model predictive control is used to predict the future dynamic information in order to ensure the safe driving of the vehicle under the attack of potential opponents. Simulation results show that the proposed scheme is capable to deal with hacking attacks.
Key words:  information security  steer-by-wire  event-triggered  attacking by hacker  Lyapunov stability
