The invention discloses a steering control method of engineering machinery and the engineering machinery. The engineering machinery comprises a steering oil cylinder, a motor and a steering wheel. The steering oil cylinder is used for driving engineering machinery to steer. The motor is in driving connection with the steering oil cylinder. The motor is in signal connection with the steering wheel so as to drive the steering oil cylinder to act when the steering wheel rotates, the steering control method comprises the following steps that the load state of the engineering machine is obtained, the corresponding set rotating speed and the corresponding initial rotating speed are obtained according to the load state, and the initial rotating speed is smaller than the set rotating speed; acquiring actions of a steering wheel; and when the steering wheel rotates, controlling the motor to work at the initial rotating speed and controlling the motor to work at the set rotating speed after a set time period. When an operator starts to rotate the steering wheel, the motor is controlled to work at a low initial rotating speed, so that impact generated when the steering oil cylinder is just started is reduced, and steering stability is improved. And after the set time, the motor works at the set rotating speed, and the smoothness of the steering process is guaranteed.

    本申请公开了一种工程机械的转向控制方法和工程机械。工程机械包括转向油缸、电动机以及方向盘。转向油缸用于驱动工程机械转向。电动机与转向油缸驱动连接。电动机与方向盘信号连接以在方向盘转动时工作来驱动转向油缸动作,转向控制方法包括如下步骤:获取工程机械的负载状态并根据负载状态获取对应的设定转速和初始转速,初始转速小于设定转速;获取方向盘的动作;以及在方向盘转动时,控制电动机以初始转速工作并在设定时间段后控制电动机以设定转速工作。当操作人员开始转动方向盘时,控制电动机先以较低的初始转速工作,以减小转向油缸刚启动时的冲击,提高转向稳定性。在设定时间后使电动机以设定转速工作,保障转向过程的流畅性。
