STPA application when analyzing vehicle systems functional safety
EDN: IWQARR
Abstract
Introduction (problem statement and relevance). Steady growth of the number of electronic units within modern vehicles generates a complex of new hazards and risks, which were not previously considered at the vehicle life cycle stages. This circumstance obliges the developers and manufacturers to develop and search for new methods or their combination able to ensure the design parameters of vehicle systems safety levels to the fullest extent. Purpose of the study. The study suggests using the System Theoretical Process Analysis (STPA) method at the early stages of procedures for ensuring functional safety of electronic and electric systems of highly automated vehicles.
Methodology and research methods. The paper analyzes joint application of the safety analysis methods specified in GOST R ISO 26262-3 and the STPA method.
The scientific novelty consists in synthesis of these approaches within the highly automated vehicle systems study.
Practical significance. The results of application of the combined safety analysis form the basis of existing and promising developments of new electronic systems of highly automated vehicles and can also be used when modernizing and upgrading existing electronic systems being operated.
