The invention discloses a control method of a double-drive electric forklift. The control method comprises the following steps that steering information of a master angle sensor and steering information of a slave angle sensor are correspondingly obtained, and the master angle sensor and the slave angle sensor are correspondingly arranged at a steering knuckle master pin of a steering axle; the steering information is transmitted to a steering signal processor and output information is determined; and the output information is output to a motor controller, and a traction motor of the double-drive electric forklift is controlled through the motor controller. The two angle sensors are adopted to implement control, the problem of unbalanced current of the traction motor caused by angle identification errors is effectively avoided, and large-current heating of the traction motor caused by abnormal load is avoided.
本发明公开了一种双驱电动叉车的控制方法,包括以下步骤:分别获取主角度传感器和从角度传感器的转向信息,其中,所述主角度传感器和从角度传感器分设在转向桥的转向节主销处;所述的转向信息传输至转向信号处理器并确定输出信息;将所述的输出信息输出至电机控制器,并通过该电机控制器控制双驱电动叉车的牵引电机。本发明采用两个角度传感器实施控制,有效的避免了由于角度识别误差导致的牵引电机电流不均衡的问题,避免了牵引电机因负载异常导致的大电流发热。
