摘　　要：针对两轮转向弯道行驶时操纵稳定性差的问题,设计了四轮转向控制系统,该系统以AT89S52作为中央处理器,主要由传感器模块、信号采集调理电路、转向电机及传动机构等组成。与两轮转向相比,4WS(Fourwheel Steering)控制系统能有效地提高低速转向时的机动性和高速转向时的操纵稳定性,便于汽车高速行驶时转急弯和变线调整,减小调头时的转弯半径。For two-wheel steering cornering manoeuvre stability problems, a design of the four wheel steering control system based on AT89S52 is proposed to overcome the shortage. AT89S52 is taken as the central processor of the system, which is mainly composed of sensor module, signal acquisition and conditioning circuit, steering motor and a transmission mechanism. The results show that 4WS （four-wheel steering） system of control can effectively improve the low-speed steering maneuverability and high speed steering handling stability compared with two-wheel steering. And the system can facilitate high-speed ear for sharp turn and variable line adjustment, and decrease the turning radius in U-turn.
