ABSTRACT we designed a SIMULINK vehicle blockset that corresponds to the Society of Automotive Engineers (SAE) benchmark as a first level of CBSE architecture. We introduced a second level of abstraction where we connect each module to a Simulink DDS blockset to take advantage of the QoS parameters, events generated in response to faults or exceeding of fixed parameters and calls to callback functions, managed within the DDS middleware itself without involving the user tasks realized by the modules in the application level. The powertrain and chassis modules are connected to FlexRay bus. We chose to use the FlexRay network for its fault-tolerant dual channel bus (physically independent cables), where a node can be connected to one or both of the busses. A node connected to both busses can send the same or different messages on the two busses. Sending the same message on both busses increases the fault-tolerance. However FlexRay does not meet the bandwidth and scalability requirements of next-generation advanced driver Assistance systems, V2X and RadCom communications. Giga-Ethernet and Wireless High-speed communications are the emerging technologies in the automotive domain, specifically in the body and multimedia domains. In this paper we are interested to computations related to Ethernet and we demonstrated that the Body and Multimedia domains can be connected to it with a minimum latency budget. |
