The embodiment of the invention provides an electric forklift steering control method and system, and belongs to the technical field of forklift control. The control method comprises the following steps: judging whether a brake pedal or an accelerator pedal is treaded or not and a driver does not operate a steering wheel to rotate or not; when it is detected that a driver operates the steering wheel to rotate, the steering angle sensor detects that the steering wheel starts to rotate from a static state and detects whether the rotating speed is larger than a first rotating disc preset threshold value or not; under the condition that the rotating speed of the steering wheel is larger than a first rotating disc preset threshold value, a pump electric controller controls the rotating speed of a pump motor to be directly increased to a first motor preset threshold value and lasts for a first preset time; after a first preset time, the pump electric controller controls the rotating speed of the pump motor to be reduced to a second motor preset threshold value; judging whether the rotating speed of the steering wheel continuously increases or not; according to the control method, steering of the forklift can be triggered by triggering the steering wheel.
本发明实施例提供一种电动叉车转向控制方法和系统,属于叉车控制技术领域。所述控制方法包括:判断是否存在踩动制动踏板或加速踏板,且驾驶员无方向盘转动的操作;检测到驾驶员有方向盘转动的操作的情况下,转角传感器检测方向盘从静止状态开始转动,并检测转动速度是否大于第一转盘预设阈值;在所述方向盘的转动速度大于所述第一转盘预设阈值的情况下,泵电控控制泵电机转速直接增加到第一电机预设阈值,并持续第一预设时间;经过第一预设时间后,泵电控控制所述泵电机转速降到第二电机预设阈值;判断方向盘的转动速度是否持续增大。该控制方法通过触发方向盘即可触发叉车的转向。
