Comprehensive Assessment of Failures and Risks of the Information System “Driver-Vehicle-Environment”

This publication is a continuation of the authors’ research in the field of transportation system automation. The authors have identified the conditions of influence of the “driver-vehicle-environment” information system (DVE-IS) on the functional state of the vehicle based on preliminary results. The article presents the results of a comprehensive assessment of factors influencing the DVE-IS. Each component of this system functions as a specific separate system, forming in individual subsystems, with specific purposes and functions and its own manifestation of failures in functionality. However, a new type of component failure arise in the process of combining them into one system. Therefore, it is necessary to identify the reasons for failures in the newly formed system and assess their level of influence on the system. The assessment was conducted by comparing the results of a survey of respondents and conclusions of experts in the automotive industry. The publication discusses a comprehensive approach to analyzing the causes and consequences of failures (failure mode and effects analysis (FMEA)) of the DVE-IS using Ishikawa diagrams. Factors leading to failures affect the system during implementation of the information computing system (ICS) for processing vehicle control signals. The author provide a scheme for identifying the interrelationships of failure causes in the ICS at different levels of transmission of control signals of the DVE-IS is provided. A significant result of the research is the discovery of a new structure of ICS levels. Recommendations are provided for a comprehensive quantitative and qualitative assessment of the causes of failures and risks of the DVE-IS.
