Analysis of the safety functions according to ISO26262 of the Epic0 vehicle and critical overhaul of the control board

Safety has always been an important part, independently on the field of work that it accounts for. Nowadays, road vehicles, including trucks, are characterized by an increased complexity due to a greater variety of software, and a greater number of sensors and actuators. As a consequence, there is an increased risk of failures, both HW and SW, that could lead to unacceptable hazards. The presence of these risks led to the definition of functional safety, a crucial property that must be ensured to avoid or mitigate these potential unacceptable hazards. Functional safety standard that is currently used in the automotive domain is the ISO 26262, an adaptation of the IEC 61508 safety standard. The version of ISO 26262 that is used in this thesis is the final draft released in December, 2016. Various parts of the ISO 26262 functional safety standard had been considered and applied, during stage and thesis work, in order to understand the differences and interdependencies between them, as follow: ¿??Part 1: Vocabulary, ¿??Part 3: Concept phase, ¿??Part 4: Product development at the system level, ¿??Part 5: Product development at the hardware level, ¿??Part 6: Product development at the software level, ¿??Part 9: Automotive Safety Integrity Level (ASIL)-oriented and safety-oriented analyses By now, L7e vehicles do not have to be compliant with the standard. However, it is likely that by 2022 they will have to. To be ready by 2022, Mecaprom Technologies Italia and Regis Motor are interested in investigating ISO26262 as well as safety case provision. Thus this thesis focuses on the adaptation of the torque management system to the ISO 26262 standard, focusing on the evolution of the LMU board from the old version (2017) to the latest version (2022).
