Flexray is designed to ensure high performance in difficult conditions. Non -shielded twisted steam is used to connect nodes in many different wiring models. Support for differentiation with a single or double communication channel is designed to reduce the effect of noise on the system without increasing cost by using expensive shielding. Flexray two -channel systems are usually used to increase tire failure and ECU. Flexray layouts include a multi -point connection diagram, a Zvezda network, as well as a hybrid network. The multi -point tire topology is the same as in Can and LIN systems, and it uses one tire to connect several processors together. This system helps in implementation with other systems due to such a CAN and LIN network layout. The topology of the Zvezda network consists of several blocks of the EU connected to the central active node. This layout is useful in the fact that if one processor is cut off or disconnected, the rest of the processors continue to function. The topology of the hybrid network is a combination between the Multi-Shina and Star-shaped network. Such a layout combines the reliability and profitable advantages of two other layouts, and this will most likely be the future of Flexray technology.
