The invention relates to a front wheel turning abnormal deflection warning method, which comprises the following steps of: (1) finishing power-on self-test of a front wheel turning control box, and starting turning/anti-swing control; (2) a front wheel turning control box judges whether the system is in a turning state or not, if not, the system enters an anti-swing state, front wheel abnormal deviation judgment is not carried out, and an electromagnetic valve in a combined hydraulic valve is powered off in the anti-swing state; if yes, front wheel abnormal deflection and over-limit logic judgment and disposal are carried out; (3) the front wheel turning control box reads the instruction sensor signal ZL, the feedback sensor signal FK and the inertial navigation ground speed DS, and the front wheel turning control box calculates the deflection angle of the front wheel at the current speed, namely the feedback sensor theoretical position signal FKL; (4) the front wheel turning control box outputs control current according to a servo valve control current algorithm according to the difference value between the feedback sensor theoretical position signal FKL and the feedback sensor signal FK; (5) front wheel abnormal deflection judgment and treatment; and (6) front wheel overrun judgment and treatment.
本发明涉及一种前轮转弯异常偏转的告警方法,包括步骤:(1)前轮转弯控制盒上电自检完成,开始转弯/防摆控制;(2)前轮转弯控制盒判断系统是否处于转弯状态,若不是,系统进入防摆状态,不进行前轮异常偏判断,防摆状态下组合液压阀内部的电磁阀断电;若是,进行前轮异常偏转和超限逻辑判断和处置;(3)前轮转弯控制盒读取指令传感器信号ZL、反馈传感器信号FK及惯导地速DS,前轮转弯控制盒解算出当前速度下前轮应偏转的角度,即反馈传感器理论位置信号FKL;(4)前轮转弯控制盒根据反馈传感器理论位置信号FKL和反馈传感器信号FK的差值,按伺服阀控制电流算法输出控制电流;(5)前轮异常偏转判断和处置;(6)前轮超限判断和处置。
