At the SAE Convergence, America's most distinguished automotive electronics event, the MOST Cooperation will demonstrate that the MOST technology is now ready to set off for new horizons. The group plans to enhance the market position of its bus system hitherto used solely for multimedia data transport. New domains targeted include connected services and driver assistance systems.
MOST150, the wideband-enhanced version of the MOST bus is ready to support all major fields of in-car use cases, the group said. In order to achieve that goal, the system now supports several new topologies including star, daisy-chain and tree. The group has also created a number of additional physical layers such as plastic optical fibres (POD), coax cable and unshielded twisted pair (UTP).
The group sketches a new world of automotive connectivity options, with MOST150 being the network technology of choice. In future vehicle generations, internet access devices, consumer gadgets, cameras, video processing units for back-seat entertainment and driver information systems will generate large amounts of data – and require massive internetworking. Currently, several car makers are already about to implement MOST150 in serial projects.
But the MOST Cooperation aims even higher than just infotainment. Future driver assistance systems will heavily be based on sensor fusion as the combination of data from different sources is called. Navigation systems, radioed traffic information and functional warnings as well as radar- and camera-based assistance systems will access a common pool of data in order to implement advanced functions that already covering safety-relevant aspects. This is where the MOST Cooperation aims. Recent studies prove that MOST150 is fit to support those functions, the group states.
Join our online Radio Show on Friday 11th July starting at 2:00pm Eastern, when EETimes editor of all things fun and interesting, Max Maxfield, and embedded systems expert, Jack Ganssle, will debate as to just what is, and is not, and embedded system.
