MOST technology aims at safety-critical applications
As the network of choice to connect drives assistance systems with dashboard displays or ECUs controlling the vehicle's driving behavior, MOST150 would compete with existing networking technologies such as CAN or FlexRay. However, the MOST group targets in the first place future imaging systems. For these applications there is not really a standard in place yet.
In addition, with its latest enhancements, MOST is also targeting applications associated to mobile connectivity (integration of consumer electronics devices) and connected services (visual information services transmitted via mobile internet).
“MOST is now exceeding the limits of infotainment,” said Harald Schoepp, member of the MOST Cooperation steering committee. “Driver assistance functions are about to complement the functionality of the traditional infotainment systems. Along with information devices such as navigation systems, traffic information and vehicle condition information systems the number of vehicles equipped with driver assistance features such as cameras, distance control systems or lane departure warnings will increase rapidly.”
While the electronic infrastructure for driver assistance systems including sensors and networks is fairly complex, the technical specs of such infrastructure for different applications overlap to a large extend, the MOST cooperation states. None of today's existing in-car network technologies meets the bandwidth and reliability requirements associated to the next generation of driver assistance systems. The MOST Cooperation however believes that its technology comes close to these requirements. Recent studies prove that MOST is prepared for safety critical applications, the group states, without however furnishing these studies. Missing features are subject to current developments; the works focus on flexible topology options, a new physical layer and protocol enhancements. As a first step beyond purely infotainment applications, the group plans to implement network sensors based on MOST technology.
