The authors explored a complete life cycle model and examined the potential for developing information systems to support car operation processes’ organizational and functional aspects. They integrated information related to the stages of a car's life cycle and its technical control systems, which are essential for monitoring and diagnosing the condition of vehicles. Their study is based on a comprehensive approach considering the interaction between the “car - driver - operating conditions - infrastructure for car operation (including transport and highways).” They focused on implementing “systems with full responsibility,” such as FADEC (Full Authority Digital Electronic Control) systems, aiming to create integrated onboard systems for managing the operational processes of various vehicle components. The research also looked into control and diagnostic systems, as well as systems for organizational and functional support, such as IPV (Impact Protection Vehicle), CALS (Continuous Acquisition and Life Cycle Support), and PLM (Product Lifecycle Management). The authors proposed and developed various information software complexes (ISC) and algorithms for their operation. They presented the results of their studies on fuel consumption under controlled experimental conditions.
