There are many benefits in having autonomous and cooperative vehicles, for example, unmanned aerial vehicles or cooperative smart cars, which could operate efficiently in stringent conditions, such as the monitoring of ash clouds emitted by volcanos or in fast and dense traffic. However, existing approaches to system design did not provide sufficient guarantees that such vehicles could operate safely in public roads and air space.
KARYON addressed the problem of finding robust operating strategies for vehicles, which dynamically adjust performance to ensure safety based on actual operational conditions. Specifically, the vehicles estimate the confidence on the information they collect from a variety of sources, including other vehicles, and dependably adjust their behaviour based on that estimation.
KARYON aimed at defining a system architecture based on a small local safety kernel that would prevent dangerous behaviour. Being a very small subsystem (compared to the overall complex control system), its predictability can be justified, guaranteeing overall safety with respect to a set of safety rules.

The project provided the KARYON generic architecture, which allows system designers to build specific architectures that embody the KARYON approach and its benefits, namely achieving increased efficiency without jeopardizing safety, supported by the trusted local safety kernel.
KARYON also defined an abstract sensor model to deal with sensor faults, which provides the validity of the sensor data along with the data. This validity information is then considered by the safety kernel on each vehicle, which dependably transitions the vehicle between different levels of service in reaction to changing conditions and faults affecting the sensor data and the quality of environmental perception.
The project also developed innovative mechanisms to enhance the dependability and timeliness of wireless communication, and respective middleware and test tools. Proof-of-concept prototypes (e.g., a mixed-reality UAV simulator and real miniature cars) were developed and evaluated, validating the KARYON architecture and the general approach.
