[eng] This paper describes SOAcom, a communication
model as well as a development process to characterize and
adapt automotive network protocols to Service-based Driver
Assistance Systems (DAS). Future DAS for articulated vehicles
like a car with a caravan are characterized by a dynamic
software and hardware architecture. In these systems Serviceorientation
is a promising approach. One major demand to be
able to deploy such systems in an automotive environment is the
ability to allow Service communication through the specialized
automotive networks. This paper describes a development process
to define a communication model that is built up by mechanisms
which are necessary to allow this Service communication. The
development process, consisting of four phases, is tested by
defining a communication model for a Service-based DAS on the
Controller Area Network (CAN). The result is then evaluated by
means of a set of experiments.
