The Safety-Related Aspect of CARTRONIC 1999-01-0488

A networking of control systems poses high challenges - in particular for guaranteeing its safety, reliability, and acceptance of the whole integrated system by the car user. CARTRONIC is an open architecture for networking the control systems of a vehicle. The organization of a network has to be set up systematically and with foresight to achieve the advantages of going beyond the sum of the components and to avoid mutual disturbance. Thus the cooperation does not only require well-defined interfaces, but also coordination of the control strategies in the individual components. Additionally, there is an increasing need for ensuring that safety risks are effectively minimized, and for ensuring that no degradation in performance from either a safety or environmental point of view might take place. The paper is focused on the safety-related aspect of CARTRONIC, the safety analysis. The output of the safety analysis is a Safety Architecture. The Safety Architecture itself is based on the Function Architecture and adds from a safety point of view what is required to guarantee the safety of networking systems. The whole approach of the safety analysis is described in the form of a flow diagram.
