The invention provides a forklift steering method and device and a forklift. The forklift steering method comprises the following steps: obtaining the deflection angle of a steering wheel; based on the deflection angle, determining the differential ratio of the left driving wheel to the right driving wheel; determining a target rotating speed based on the trigger signal of the accelerator pedal; and outputting the rotating speed of the left driving wheel and the rotating speed of the right driving wheel based on the target rotating speed and the differential ratio. According to the forklift steering method and device and the forklift, the differential ratio of the left driving wheel and the right driving wheel is determined according to the deflection angle of the steering wheel, the rotating speed of the left driving wheel and the rotating speed of the right driving wheel are output according to the target rotating speed and the differential ratio, in this way, the driving wheels and the steering wheel can rotate cooperatively, flexible rotation in a small-range space is achieved, in-situ rotation can be achieved, steering control is simpler and more convenient through an electric control mode, and steering precision and accuracy are improved.

    本发明提供一种叉车转向方法、装置及叉车,该叉车转向方法包括:获取转向轮的偏转角度;基于所述偏转角度,确定左驱动轮与右驱动轮的差速比;基于加速踏板的触发信号,确定目标转速;基于所述目标转速以及所述差速比,输出左驱动轮转速和右驱动轮转速。本发明提供的叉车转向方法、装置及叉车,根据转向轮的偏转角度,确定左驱动轮和右驱动轮的差速比,根据目标转速和差速比,来输出左驱动轮转速和右驱动轮转速,这样就能够使得驱动轮和转向轮协同转动,实现小范围空间内灵活转动,能够实现原地转动,通过电控的方式,使得转向控制更加简便,提高转向精度和准确率。
