FlexRay is a new communication system that offers reliable and real-time capable high-speed data transmission between electrical and mechatronic components to map current and future innovative functions into distributed systems within automotive applications. In the same context, the real-time middleware Data Distribution Service (DDS) is an appropriate alternative for the standard vehicular middleware considering that it handles Quality of Service (QoS) parameters. An interesting innovation would be the use of the DDS middleware on top of FlexRay networks formed by FlexRay cards to guarantee the arrival of the right data on the right time. In this paper, we will use as application an extended SAE(Society of Automotive Engineers) benchmark for the FlexRay network to identify the DDS DataReaders and DataWriters, and calculate the response time, based on the full scheduling model, and introduce it into the DDS QoS to further prove that the QoS of SAE benchmark are insured.
