User manual

This document will guide you through the installation process and provide you with important information on how safeTbox works and how it integrates with Enterprise Architect. It describes the modeling and analysis techniques as well as the usability features.


This simplified Electric driving system is composed of an electric machine, its controller and its power electronics. From the user perspective, the system is primarily responsible for the acceleration of the vehicle. From the architecture perspective, the system is responsible for controlling the torque that is applied by the power electronics.

This example includes the excerps of the architecture design, HARA, Fault Tree Analysis and a safety concept


This example shows an airbag system as it would be developed by a Tier 1 manufacturer. The Aribag control Unit (ACU) is responsible for detecting a crash that would result in the deployment of the airbag and seatbelt pretensioner.

The file includes the architecture design, fault tree analysis, and safety case excerpts.


The Automated Lane Centering (ALC) system provides continuous lateral control to keep the vehicle on a reference trajectory within the lane.

This project replicates the STPA-related artifacts depicted in the report and appendices of the Functional Safety Assessment for and Automated Lane Centering (ALC) system provided by NHTSA, August 2018.
