An article over at just-auto.com gives a good overview of the project:
"Much as the software on a personal computer connects to the internet to download and install updates, the DySCAS architecture allows automotive software to automatically download patches and improvements whenever the vehicle is in range of an accessible wireless hotspot - in the owner's garage, for example, or even in a public parking lot. It could then download new maps for the navigation system, update the entertainment system to play new music formats, or even adjust engine timing based on more fuel efficient settings supplied by the manufacturer."The project is a cooperation between partners such as Volvo Technology, Daimler, Bosch and the Swedish Royal Institute of Technology
