The modern fighters needs higher improvements in aerodynamic performance and system integration, which leads to the application of Integrated Vehicle Management System (IVMS) in advanced fighters for improving the performance, reliability and maintainability, and reducing the weight, life cycle costs and complexity of wiring. The system structure, computers used, data buses and interface units of the IVMS in F-22, EF-2000 and F-35 were discussed. Then, the computer performance, fault tolerance configuration, system data bus, function integration, technical line of these systems are analyzed and compared with each other. The result showed that the new generation of IVMS will have the characteristics of highly integrated function, networked system, distributed open system architecture, high-speed data bus, highly safe partition operation system and wide application of COST.%现代战斗机设计对飞机的气动性能和功能综合提出更高的要求,这促使先进战斗机采用综合飞行器管理系统实现飞机的性能、可靠性、维修性的提高和系统重量、体积、布线的复杂性、全寿命周期费用的降低等.探讨了F-22、EF - 2000和F-35战斗机的综合飞行器管理系统的体系架构、计算机组成、系统总线和接口单元构成与主要功能；对这些系统的计算机性能、容错配置、系统总线、功能综合、技术路线等特性进行比较分析.结果表明:高度的功能综合、网络化、分布式开放系统结构,高速数据总线,高安全实时分区操作系统、COTS的广泛使用将是新一代综合飞行器管理系统发展的显著特征.
