The desire to introduce autonomous vehicles by 2020 on the roads represents a real technological challenge. It requires breaks with traditional design, security and validation processes to achieve a safe system. As part of the SVA 1 (Simulation of Autonomous Vehicle Safety) project, we present the process under development at the Institute for Technological Research SystemX 2 , in order to optimally address the limitations of existing methods. The objective is to provide designers methods and tools to support safety considerations during the design and the validation phases of autonomous vehicles functions. In this paper, we apply a Model Based Safety Analysis methodology (MBSA) to an Advanced Driver-Assistance System (ADAS), using a modular numerical simulation platform. We describe the different activities carried out during each stage and define the associated objectives. Experimental simulation results are presented, showing the advantages of such approach.

SummaryThis communication deals with the difficulties and safety needs currently observed on complex and innovating systems. The VEDECOM's autonomous vehicle is a very interesting case of these needs. The security constraints of this vehicle are particularly large because of the infinite environment, shared with unknown stakeholders. This presentation will first expose the safety methodology developed by APSYS and VEDECOM institute in order to increase the performance and error tolerance of the autonomous system. In a second step will be described the added value of the model based safety analysis and more specifically with SIMFIA software package.
