DESH-G model and Preliminary Architecture for Multiple ADAS system

Abstract

Various Advanced Driver Assistance Systems (ADAS) become prevailing recently. In this paper, we argue the safety analysis of combined ADAS systems. The definition of ADAS is vague, so we obey the definition of Code of Practice for the Design and Evaluation of ADAS (CoP) (1). In this definition, the ADAS have to be active, that is, it “provide(s) active support for lateral and/or longitudinal control”. There is a technical report that provides the consolidation way of various warnings emitted by the several ADAS systems (ISO/TR 12204 (2)). However, the problem is not limited to the warning signals. We have to consider the controller of ADAS because it is actively controlled from its definition. We need the more integrated way, and we provide a way to handle this situation by using the idea: DESH-G model.
