摘　　要：简述了轮式车辆遥控转向系统的基本结构和工作原理。给出以 TMS320LF2407A 为核心的遥控转向系统控制单元的设计方案,介绍了控制芯片、信号处理电路、驱动逻辑电路、H 桥驱动电路、电动机保护电路和故障报警电路等硬件电路的设计。设计了变结构控制算法的遥控转向控制策略,并采用奥地利 DEWTRON 公司的 DEWE2010便携式信号处理系统对控制效果进行验证,做出了120°阶跃角输入和随机信号输入的响应曲线,响应曲线表明所设计转向控制系统有较高的可靠性。The basic structure and working principle of a wheeled vehicle remote-control steering system are briefly introduced. The design scheme on control unit of the system with the core of TMS320LF2407A is put forward. The design of hardware circuits including controlling chip, signal processing, driving logic, H-bridge driving, motor protecting and fault alarming are described. The remote-control steering control strategy of variable-structure control algorithm is designed. The control effects are verified by the DEWE21010 system which is of a portable system made by an Austrian corporation DEWTRON for signal processing. The response curves of 120° angle step input and random signal input are obtained and show that the proposed system possesses high reliability,
