Summary:

The interdisciplinary and structured integration of subsystemsinto a functioning whole is at the root of Systems Engineering.Until recently in the automotive market, much of this has beenspecific to an automotive subdomain such as Telematics,Infotainment, Chassis Control, or Engine Management Systems. In therealm of Telematics and Connected Vehicles, the recent trend hasbeen outward from the vehicle, focusing on expanding connectivityand data sources. Systems Engineering for Telematics now includesmultiple transports spanning PAN, WLAN, and WAN communications, andbeyond that has grown to include entities on the far side of thenetwork link, including data servers, aggregation portals, andnetwork security.Although it was not trivial for Continental to develop theembedded Telematics connectivity subsystems for products such asGeneral Motors Corporation/OnStar®, Ford SYNC®, BMW Assist, andMercedes Tele Aid®, consumer and regulatory expectations arerendering inadequate the artificial boundary of an embeddedconnectivity domain for new automotive systems.For example, reducing vehicle weight is a common approach in theeffort to improve fuel efficiency, and weight targets have beencascaded down to each subsystem and module. However, for each 100pound weight reduction for passenger vehicles (and withoutcorresponding changes to other vehicles or additional safetytechnologies), NHTSA and other studies have indicated the effect ofhundreds of additional fatalities per year in the United States.With both safety goals and US CAFE fuel efficiency goals to meet,the design and interaction of many previously unrelated subsystemsin the vehicle become key factors, and in particular, the newinteraction between vehicle connectivity subsystems with vehiclesafety and performance subsystems.For this discussion, we take a systems view of the evolvingfield of vehicle connectivity, review the historical trends,introduce a framework to analyze several human constraints, and usethe framework to identify ideal characteristics in a modern vehiclesystem
