Nowadays, road vehicles, including trucks, are characterized by an increasedcomplexity due to a greater variety of software, and a greater number of sensorsand actuators. As a consequence, there is an increased risk in termsof software or hardware failures that could lead to unacceptable hazards.Thus safety, more precisely functional safety, is a crucial property that mustbe ensured to avoid or mitigate these potential unacceptable hazards. Inthe automotive domain, recently (November 2011), the ISO-26262 safetystandard has been introduced to provide appropriate requirements and processes.More specically, the standard denes the system development processthat must be carried out to achieve a system that can be consideredacceptably safe. To be released on the market, systems must be certied,proofs that the systems are acceptably safe must be provided in terms of astructured argument, known as safety case, which inter-relates evidence andclaims. Certication authorities are in charge of evaluating the validity ofsuch safety cases. In the automotive domain, certication and compliancewith the standard ISO-26262 is becoming mandatory. By now, trucks donot have to be compliant with the standard. However, it is likely that by2016 they will have to. Scania is one of the leading companies in trucksdevelopment. To be ready by 2016, Scania is interested in investigatingISO-26262 as well as safety case provision. Thus this thesis focuses on theprovision of a safety case in the context of ISO-26262 for Fuel Level Estimationand Display System (FLEDS), which is one of the safety-criticalsystems in Scania.1
