Safety Analysis Method for Cooperative Driving Systems

This paper researches safety analysis for a cooperative driving system. The main objective is to assess how cooperative elements in an ISO 26262 item definition affect safety goals. The architectural model of a cooperative adaptive cruise control system is developed and its functional safety is analyzed using a combination of fault tree analysis and fault classification methods. The results show that inclusion of cooperative architecture perspective affects the safety goals of cooperative adaptive cruise control because ASIL determination is influenced by vehicle-to-vehicle communication faults.
