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.
