The invention discloses a steering control system and method of a backhoe loader. The steering control system comprises a processing control unit. When a steering mode switching instruction is received, the front axle centering detection sensor and the rear axle centering detection sensor collect a front axle centering detection signal and a rear axle centering detection signal; the processing control unit is used for centering a front axle and a rear axle of the backhoe loader according to the front axle centering detection signal and the rear axle centering detection signal, and switching a front wheel steering mode valve, a rear wheel steering enabling valve, a diagonal steering mode valve and a four-wheel steering mode valve according to a steering mode switching instruction; a front wheel steering mode, a four-wheel steering mode and an oblique steering mode of the backhoe loader are automatically switched, so that the steering mode switching process is simplified; the front axle and the rear axle of the backhoe loader are automatically centered, so that the driving safety of the backhoe loader is improved.

    本发明公开了一种挖掘装载机的转向控制系统及方法,转向控制系统包括处理控制单元;当接收到转向模式切换指令,所述前桥对中检测传感器和后桥对中检测传感器采集前桥对中检测信号和后桥对中检测信号;所述处理控制单元根据前桥对中检测信号和后桥对中检测信号对挖掘装载机的前桥和后桥对中,根据转向模式切换指令切换前轮转向模式阀、后轮转向使能阀、斜行转向模式阀和四轮转向模式阀;对挖掘装载机的前轮转向模式、四轮转向模式和斜行转向模式进行自动切换,简化了转向模式的切换过程;通过将挖掘装载机的前桥和后桥自动对中,有利于提高挖掘装载机驾驶的安全性。
