Model Based Systems Engineering (MBSE) [1, 2] has emerged as a solution to the extreme design challenges caused by automotive Electrical/Electronic (EE) complexity [3]. This paper explores how coherency in early design can be applied across the entire EE design cycle. Starting from a functional abstraction, we introduce a new lightweight solution to evaluate and guide optimized implementations integrating software, networks, devices, and connectivity. The pattern used for this and the data created can be directly driven into downstream, domain-specific design flows delivering vehicle lower costs, better design quality, and faster innovation.

Correct-by-construction design processes can be dramatically enhanced using simulation techniques, especially early in the design process. But simulation is too often the preserve of specialist staff, who may work disconnected from day-to-day design updates. This paper highlights simulation and analysis tools that can be used by every electrical engineer, addressing topics ranging from functional verification to component sizing to failure modes and effects analysis. Furthermore, valuable results can be obtained with the simplest of models; and the models themselves can mature as the organization's use of simulation matures.

Manufacturing companies are benefiting from technology in most key areas of the flow from design through manufacture. This applies to the wire harness industry which is a key element of the modern automotive industry. Wire harness manufacturing engineering, however, is a critical path function that is under severe pressure and yet has been under-served by technology. In some respects it has become the weak link in the chain. Recent innovations in commercial off-the-shelf (COTS) technology are set to change this situation. Software applications are now available to deliver transformational manufacturing engineering automation as well as being able to integrate with technology in other areas of the process. This will enable a digitally continuous data flow that can remove excessive cost, time, and pressure - while helping manufacturers meet the increasing demands of the industry.

The architecture of vehicle electrical systems is changing rapidly. Electric and hybrid vehicles are driving mixed voltage systems, and cost pressures are making conductor materials like aluminum an increasingly viable competitor to copper. The challenge of assessing the impact of these technologies on vehicle safety and of understanding cost/weight trade-offs is a critical design activity. This session will discuss and demonstrate tradeoff studies at the vehicle level, show how to automatically generate an electrical Failure Mode Effects and Analysis (FMEA) report, and optimize wire sizes for both copper and aluminum at the platform level.

Demand for increased functionality in automotive electrical/electronic (E/E) systems is being propelled by both customers and various governmental regulations and requirements. This demand for more capabilities also introduces new challenges for OEMs who are responsible for implementing these functions. Of course, the cost of system development and manufacturing are considerable, but there are challenges beyond cost that the OEM must deal with, such as increased weight, reliability and quality concerns, exponentially-increasing complexity, and the government requirements. From the point of view of the electrical system platform as a whole, it provides the unique role of integrating all the individual E/E systems. When integrated, unanticipated problems can emerge that require design modifications. Often, these are discovered way down the design path, which results in delays in the program that can lead to missed deadlines and costly rework.
