Abstract
Cyber-physical systems (CPS) allow the rapid and reliable development and integration of computer- and information-centric physical and engineered systems. They represent a new generation of engineered systems that are highly dependable, efficiently produced, and capable of advanced real-time performance in information, computation, communication, and control. The automotive sector is a rich target for emerging innovations in CPS. Thanks to tens of electronic control units (ECUs), sensors and actuators now deployed in modern automobiles, features such as adaptive cruise control, lane departure warning, automated parallel parking, and traction control have become feasible. Nevertheless, the design and development of these features tend to be traditional in nature, and extensive testing must be conducted to deliver assurance at a significant cost. Even with extensive advances in mechanical safety and growth in passive safety devices, such as airbags, the industry continues to pursue methods to reduce the occurrence of injury. About 42,000 fatalities and 1.5 million injuries occur every year on US roads from automobile accidents representing opportunities for societal improvement. Delays due to traffic congestion waste enormous amounts of user productivity and finite energy resources. Alternative designs and energy sources driven by user demand and new CAFE requirements also necessitate complex real-time control. This need to improve how automobiles are designed also applies to how they are manufactured. Automotive manufacturing is a substantial part of the North American economy accounting for close to 5 percent of the U.S. private sector gross domestic product.
