A cyber-physical system (CPS) is made up of tightly-integrated computation, communication and physical elements. Therapeutic devices, buildings, mobile devices, robots, transportation and energy systems can gain from CPS co-design and optimization techniques. Cyberphysical vehicle systems (CPVSs) are swiftly advancing due to improvement in real-time computing, control and artificial intelligence. Comprehensive or multi-objective design optimization maximizes CPS efficiency, capacity and safety,

This paper surveys the run-time cooperative optimization or co-optimization of cyber and physical systems, which have historically been considered individually. A run-time CPVS is also cooperatively regulated or co-regulated when cyber and physical resources are used in a manner that is responsive to both cyber and physical system requirements. This paper studies research that considers both cyber and physical resources in co-optimization and co-regulation schemes with applications related to vehicle systems andmobile robotics. Time-varying sampling patterns, sensor scheduling, anytime control, feedback scheduling, task and motion planning and useful resource sharing are examined. I. INTRODUCTION A cyber-physical system (CPS) is "the next generation of system that requires restricted integration of computing, communication, and control technologies to achieve stability, performance, stability, robustness, and efficiency in working with physical systems of numerous application domains". A cyber-physical vehicle system (CPVS), which are ranging from automobile to aircraft and marine craft, is composed of tightly-coupled locomotion, computational and communication components. Historically, CPVS development has been powered by advances in closely-related (but not identical) autonomous vehicle research and cooperative vehicle control to increase system capacity and improve safety and efficiency . CPS research generally aims to synergistically integrate control, computing, communications and physical systems in novel ways that leverage interdependent behavior. CPSs have broad applicability and have been the topic of numerous committee workshops and reports focused on identifying and addressing next-generation opportunities and challenges. Consumer devices, such as smartphones, multimedia players and gaming systems, respond to voice commands, and wearable electronics are ubiquitous. Smart buildings are equipped with advanced sensors, pervasive networking and efficient energy management systems . Advances in medical devices can lower costs and improve patient care . New software-enabled functionality, increased connectivity and physiologically closed-loop systems have the potential to reduce human error that can cost lives A new energy service system dubbed the "smart grid" promises to utilize CPS technologies to increase configurability, adaptability, reactiveness and self-manageability , but will simultaneously require CPS breakthroughs in security to monitor, manage and thwart threats both to the physical entities comprising the grid, as well as the cyber attacks on its networked components . Most relevant to the work in this paper is the application of CPS research to vehicle systems. In this
