A Systematic Method for the Development of a Functional Safety Concept

Abstract

The comfort we gain from our passenger cars is very much offset by the dangers to our climate caused by the energy consumption and exhaust of the cars. Complex electronic controls in the cars can reduce the energy consumption but raise the probability of dangerous unwanted behaviour. The requirements of ISO 26262 on the design of safety related functionality shall reduce these dangers. We present the architecture and design principles of our functional safety concept, that fulfils the requirements of ISO 26262 as well as the requirements of our platform concept for systems engineering work products. The key enabler for the design and maintenance of our functional safety concept are distinct views we employ to show important aspects of the set of safety requirements.
