摘　　要：LabVIEW FPGA模块具有灵活性、高性能,以及可定制化能力,CompactRIO硬件提供高性能的可重复配置I/O,保证实时性要求,因此利用LabVIEW FPGA模块和CompactRIO硬件作为线控转向硬件在环仿真试验系统的开发工具和基础。首先对试验系统的总体结构和工作原理进行了概述,对系统的实时硬件和软件系统进行了设计。针对线控转向系统的实现必须以路感模拟算法和转向控制算法为基础,对系统路感控制算法和转向控制算法进行了重点设计和仿真试验。结果表明所设计的线控转向硬件在环系统非常适合线控转向系统控制算法的测试,采用的控制算法具有良好的控制效果。Lab VIEW FPGA is flexible ,high performance ,and capacity can be customized. The real- time hardware（ CompactRIO ）has high speed I/O interface that can be repeat deployed. So LabVIEW FPGA and CompactRIO system are suitable for design of Steer-By-Wire Hardware-in-the-Loop simulation system. First introduced the system overall structure and working principle. Then details of the system＇s real- time hardware system and software system were introduced, In view of SBW system must take the road feeling algorithm and steering control algorithm as the foundation,the Road feeling algorithm and steering control algorithm are designed and tested with the simulation system. The test results verify this system is suitable for developing and evaluate the SBW system and control algorithms have the good control effect.
