The invention provides a steering control method and system, a steering system and electric engineering machinery, and is applied to the technical field of electric engineering machinery, the control method determines the demand flow of a steering oil pump based on the rotation speed of a steering wheel after the rotation speed of the steering wheel is obtained, and thus the rotation speed of a steering motor is adjusted based on the demand flow. According to the steering control method, the rotating speed of the steering motor is adjusted on the basis of the required flow of the steering oil pump determined through the rotating speed of the steering wheel, so that on-demand oil supply is achieved, invalid idling is avoided, in other words, neutral position loss is avoided, meanwhile, a coaxial amplification steering gear and a priority valve can be omitted for a steering system applying the method, and cost is reduced. And the reversing valve is adopted to control steering, so that the load sensing loss and throttling loss of the steering gear as well as the local loss and overflow loss of the priority valve are eliminated.

    本申请提供一种转向控制方法、控制系统、转向系统及电动工程机械,应用于电动工程机械技术领域,该控制方法在获取方向盘转速后,基于方向盘转速确定转向油泵的需求流量,从而基于需求流量调整转向电机的转速。本发明提供的转向控制方法,基于通过方向盘转速确定的转向油泵的需求流量,调整转向电机的转速,从而做到按需供油,避免无效空转,也即避免了中位损失,同时,使得应用本发明方法的转向系统可以取消同轴放大转向器以及优先阀,而采用换向阀来控制转向,进而消除转向器的负荷传感损失和节流损失,以及优先阀局部损失和溢流损失。
