Future transportation is expected to be connected, cooperative, and highly automated. Classic automated vehicular functions are developed based on safety principles primarily, but the reliability and cybersecurity of wireless communication processes pose new challenges for the automotive industry for connected vehicles, representing Connected, Cooperative and Automated Mobility (CCAM) systems as cyber-physical systems. Since CCAM system safety is significantly affected by network performance metrics, we need to consider communication factors such as end-to-end latency and packet delivery ratio during the safety evaluation of highly automated vehicle functions. This study presents a methodological framework which links the safety of the CCAM systems with the cyber security sensitive network performance metrics, as well as the vehicle dynamics factors in order to evaluate the effect of intentional or unintentional communication failures. Accordingly, we introduced a new approach to characterize the safety risk of specific Vehicle-to-Vehicle (V2V) applications. Beyond this, severity of collision and message reception probability functions were introduced to further investigate the safety of the analyzed application. Finally, the values of the safety risk index for different warning intervals are summed, which suggest that the safety effect of specific function-related parameters could be and shall be represented during the function development process.

V2V通信的安全风险重点分析,特别是考虑网络攻击敏感的网络性能和车辆动力学因素

未来的交通有望实现互联、协作和高度自动化。经典的自动驾驶汽车功能主要基于安全原则开发,但无线通信过程的可靠性和网络安全性为汽车行业的互联汽车带来了新的挑战,将互联、协作和自动移动 (CCAM) 系统表示为信息物理系统。由于 CCAM 系统安全性受网络性能指标的影响很大,因此在高度自动化车辆功能的安全性评估中,我们需要考虑端到端延迟和数据包传递率等通信因素。本研究提出了一个方法框架,将 CCAM 系统的安全性与网络安全敏感的网络性能指标联系起来,以及车辆动力学因素,以评估有意或无意通信故障的影响。因此,我们引入了一种新方法来表征特定车对车 (V2V) 应用的安全风险。除此之外,还引入了碰撞严重性和消息接收概率函数,以进一步研究分析应用程序的安全性。最后,将不同预警间隔的安全风险指数值相加,表明特定功能相关参数的安全效果可以并且应该在功能开发过程中得到体现。我们引入了一种新方法来描述特定车对车 (V2V) 应用的安全风险。除此之外,还引入了碰撞严重性和消息接收概率函数,以进一步研究分析应用程序的安全性。最后,将不同预警间隔的安全风险指数值相加,表明特定功能相关参数的安全效果可以并且应该在功能开发过程中得到体现。我们引入了一种新方法来描述特定车对车 (V2V) 应用的安全风险。除此之外,还引入了碰撞严重性和消息接收概率函数,以进一步研究分析应用程序的安全性。最后,将不同预警间隔的安全风险指数值相加,表明特定功能相关参数的安全效果可以并且应该在功能开发过程中得到体现。
