Automotive product engineering is highly complex. Understanding the implications and opportunities of introducing new technology needs to be identified as early as possible in the vehicle design process. These earlier design considerations have the potential to deliver right-first-time designs and maximize integration opportunities, resulting in efficient, effective, competitive and holistic design solutions. Integrating new technology into existing vehicle architectures can preclude and restrain the opportunity for engineers to invent, discover and deliver new design solutions. To avoid this potential loss of opportunity, it is necessary to trace back to vehicle-level assumptions and attributes to confirm the technology delivers the desired output. The vehicle and system analysis enables engineers to consider all vehicle attributes and how their sub-system can enhance other vehicle systems.

Failure Mode Avoidance Approach for Hybrid Electric Vehicle Systems

Adoption of new technology with ever increasing complexity challenges organizational structures and processes as subsystem ownership crosses several powertrain subsystem boundaries (and thereby involves multiple departments). Integrating such technology without introducing inadvertent failure modes can be a difficult task. This paper illustrates an upfront approach to understanding the potential system impact of using an example new technology. In product development activities involving primarily reuse of known technologies, organizational and subsystem boundaries are generally clear. Interfaces are well established and responsibilities for managing failure mode avoidance are generally known. Implementation of new technology which does not naturally fit the well-established organizational definitions and boundaries presents distinctive challenges to system design, system integration, and verification using failure mode avoidance (FMA).

Automotive Product Development organisations are challenged with ever increasing levels of systems complexity driven by the introduction of new technologies to address environmental concerns and enhance customer satisfaction within a highly competitive and cost conscious market. The technical difficulty associated with the engineering of complex automotive systems is compounded by the increase in sophistication of the control systems needed to manage the integration of technology packages. Most automotive systems have an electro-mechanical structure with control and software features embedded within the system. The conventional methods for design analysis and synthesis are engineering discipline focused (mechanical, electrical, electronic, control, software).
