A COMPREHENSIVE SYSTEM APPROACH TO ANSWER THE CHALLENGES OF FUNCTIONAL SAFETY
The integration of various technologies into trucks, including information technology and electronics managed by computers, means that the systems are increasingly complex. They include a larger number of interacting elements. These systems have intricate behaviours that make them harder to predict.
While systems become more and more complex, the competitiveness of the global market places ever stricter constraints on electronics technicians regarding cost and time. This dual constraint is all the more real because it concerns the quality of systems, especially when it involves a risk to human lives or a significant financial risk. The functional safety approach allows products to be placed on the market with controlled risks.
Functional safety, which is becoming increasingly important in system design, must be included in system engineering processes. The properties of functional safety are the result of interdependencies that exist in the system and in the system’s interaction with its environment. For this reason, ACTIA handles functional safety analysis using a global approach.
As with cybersecurity, ACTIA proposes a comprehensive functional safety approach throughout all phases of the product’s life, from design to the end of the product’s life-cycle. As part of its functional safety approach, ACTIA :
MORE THAN A DEEP KNOW-HOW, A STATE-OF-MIND
ACTIA uses all its know-how and expert resources to manage the functional safety of the products developed. In addition, ACTIA provides support for safety management activities, such as hazard and risk analysis or DFMEA (Design Failure Mode and Effects Analysis): this mode focuses on the design to reduce the risk of product failure.
A team dedicated to Functional Safety
At ACTIA, Functional Safety is a collaborative task that is carried out in a multidisciplinary manner but is supervised by the Project Safety Manager.
The Project Safety Manager is required to direct, supervise, monitor and commission RAMS (Reliability – Availability – Maintainability – Safety) studies for products, together with the development team. He identifies and documents the parts relating to dependability and does so in accordance with the automotive functional safety standard: ISO 26262.
The Project Safety Manager guarantees that the architecture and product development comply with the standard. He is involved right from the stage at which the product architecture is defined and sets the guidelines that must be followed and the constraints that must be respected.
The team works in accordance with these guidelines in order to achieve a high level of functional safety.

A powerful management tool
This tool allows ACTIA to concatenate three analyses in a single tool:
When the level is not considered sufficient, the tool makes it possible to:
