The rapid growth of vehicle feature content continues to challenge automotive designers. The total vehicle feature content seriously impacts the manufacturing complexity of any single vehicle. Traditional strategies for introducing new features into high-content luxury vehicles before moving the feature into economy vehicles have been undermined by the fast moving consumer electronics field. The challenge for automotive OEM and Tier 1 suppliers is to optimize the vehicle architecture in order to provide more efficient means of introducing features expediently and efficiently. Therefore, any production vehicle's Electrical, Electronic, & Software (EES) architecture must successfully support modular sourcing, modular assembly, global manufacturing schemes, cost and weight issues.
