The goal of this workshop series is to continue to define and refine the technology needs and gaps for deeply-embedded software-intensive electronic control systems that interact deeply with the physical world in ways that have stringent reliability, availability, and safety requirements

The two foci of this submission are:
i. Component-based engineering versus architecture driven engineering
ii. Safety and Functional Safety is a Requirement

The current trend in the automotive industry is the expanded use of embedded electronics connected to physical sensors and actuators in an effort to increase the functionality, robustness, and safety of new vehicles. Automotive safety, in an effort to prevent crashes and to protect the occupants in emergency situations, provides an ideal application for emerging innovations in Cyber-Physical Systems (CPS).

Automobile is an important application of CPS (Cyber Physical System). However, current software development process in the automotive industry is not adequate to solve the unique problems of CPS. This paper pinpoints the limitations of the current automotive software development process in the perspective of CPS and proposes a new kernel-based approach called HW componentizing kernel as a solution.

Integration of various sub-systems has been one of the most time consuming and costly endeavor in the automotive domain. For example, in automotive industry the vehicle control system rely on system components manufactured by different vendors with their own software and hardware. What is needed is a new system science that enables the reliable and cost effective integration of independently developed system components.

Given the critical importance of due consideration of human factors in the design of new applications of Cyber-Transportation Systems (CTS), this position paper argues for the need for developing integrated human-in-the-loop Research, Development, Testing and Evaluation (RDT&E) facility. The paper then presents a proposed Integrated Traffic-Driving-Networking simulator which the authors are beginning to develop. This is followed by a brief description of a longer-term vision for an integrated testing facility for CTS under extreme events.

A recent trend in the automotive industry is the rapid inclusion of electronics, computers and controls that focus entirely on improved functionality and overall system robustness. This makes the automotive sector one of the richest targets for emerging innovations in Cyber-Physical Systems (CPS) [1]. While this trend has affected all of the vehicle areas, there is a particular interest in active safety that effectively complements passive safety. Passive safety is focused on the structural integrity of the vehicle.

This position paper discusses limitations of the current automotive transportation active safety systems. A system approach can address all levels (the driver, the vehicle,and the traffic) of interconnection between machine, computer and human by leading to incorporating interactions and heterogeneity of different physical layers in a unified framework. The resulting analytical and computational infrastructure, with applications in crash avoidance and traffic flow management, is then discussed.

This position paper describes the challenge of ensuring run-time safety in cyber-physical systems. The overarching problem is ensuring that computer-based systems will maintain safe operations even in the face of design-time and run-time faults. One way to address this problem is by creating an ability to perform run-time safety checks on CPS applications that can be used to record hazards, trigger emergency shutdowns (where doing so is safe), or perform other actions to minimize the consequences of an unsafe system behavior.
