In the pursuit of full electrification in the automotive sector, components of vehicular systems have seen a notable shift, with the replacement of conventional mechanical components for their electrical counterparts becoming commonplace. An example of this is the electric water pumps for cooling systems. In contrast, the adoption of electric oil pumps, while promising for enhanced efficiency, has been met with reservations due to the critical role of oil circulation in ensuring engine reliability. This study delves into this topic by conducting a comprehensive analysis of the hydraulic system within automotive contexts, applying a specific focus on electric oil pumps in electrical powertrains. This research has two main objectives: first, to analyze the hydraulic system's complexities in modern vehicles; and second, to establish a robust model for studying the behavior of electric oil pumps. Achieving these objectives entails formulating and evaluating an optimized system under the standards guidelines, which not only will ensure an efficient oil circulation but also addresses concerns related to functional safety. To achieve these goals, this study meticulously considers diverse norms associated with functional safety and employs Failure Modes and Effects Analysis (FMEA) as a critical analytical tool. By interlacing engineering principles with safety considerations, the research aims to provide insights into the reliability and viability of incorporating electric oil pumps. Through systematic analysis and software-based simulations, this study contributes to advancing electric oil pump technology in the automotive sector. The findings shed light on the feasibility of adopting electric oil pumps and underscore the importance of developing precise control strategies that align with stringent safety standards. As the automotive industry continues to embrace electrification, this research bridges the gap between innovation and dependability, facilitating the evolution of automotive systems toward a more sustainable and efficient future.
