Abstr：During the past few decades, more and more hydraulic components in vehicles have been replaced by electronic control units （ECU）. The increasing number of ECUs leads to the larger demands for real-time and high-speed communication between ECUs. As a result, communication network has become an inevitable trend in vehicles. Compared with the traditional controller area network （CAN） bus, FlexRay bus has great advantages in transmission efficiency, reliability and flexibility. Since it can meet the future requirements of network communication between ECUs, it has been applied to the power system, chassis system and X-by-wire system in some vehicles. However, how to guarantee the safety and reliability of FlexRay network communication has become an important problem. AUTOSAR NM （automotive open system architecture network management） possesses the functions of the state real-time monitoring and the cooperative sleep of network nodes, which are suitable for the vehicular FlexRay network management. AUTOSAR FlexRay NM mainly consists of 3 basic modes： bus sleep mode, synchronization mode and network mode. Based on the AUTOSAR NM, a network communication management method with fault detection function is proposed and designed. First, a FlexRay network of an automotive chassis and AUTOSAR NM is described. Second, the network internal nodes’ state transition model of network communication management is established. For this model, besides normal operation state, repeating message state and state of preparing for sleep in AUTOSAR NM, a state of Error check is introduced to identify the communication faults of network nodes. Third, a distributed fault detection state mechanism is designed for the Error check state. Finally,
