Abstract: The car can meet the high demand of the security and stability of the system by using FlexRay bus, while it also can implement optimization of the cost. The paper introduces a system of nodes’ communication based on FlexRay technology, and the system constructed two nodes which are composed of main processors, communication controllers and bus transceivers. The paper implements the transmission of data between main processors and communication controllers by EBI (external bus interface). It is succeed in implementing the communication process of receiving data and sending data among different nodes. The results show that the data completely correct while the data rate is 10Mbps. Therefore, it verifies the reliability and real-time communication of FlexRay. And it also means that the designed node will play a significant role in X-By-Wire.

Abstract: The paper presents the low cost redundancy interface applied in distributed servo system of unmanned aerial vehicle(UAV).Digital bus and analog dual-redundancy control interface is implemented, it can switchs to analog interface automatically when the digital bus works abnormally, the reliability and the antijamming capability of servo system are made to be promoted. CAN bus is chosen to be the UAV digital bus after analyzing the distributed servo system structure and servo equipments work condition. The operating principle of redundancy interface is expatiated, the hardware interfaces and the software process are provided,and the communication network performance is also analyzed. Both ground test and flight test indicate that the redundancy interface works steadily, CAN bus channel can switch to analog channel fast and smoothly, it can meet the needs of UAV flight control system.
