Abstract

The present application relates to the technical field of engineering machinery, and specifically provides a torque control method and control system of a driving motor and an electric loader. The torque control method comprises the following steps: presetting a plurality of different working condition modes of the electric loader, establishing a working condition identification standard for determining the working condition mode in which the electric loader is currently located, and setting corresponding loading and unloading strategies for different working condition modes; obtaining current working condition information of the electric loader, determining the working condition mode of the electric loader based on the working condition identification standard; obtaining an actual torque currently fed back by the driving motor, and determining a target torque of the driving motor based on the opening degree of the accelerator pedal and the current vehicle speed; and controlling the output torque of the driving motor based on the loading and unloading strategy corresponding to the current working condition mode, so that the actual torque approaches the target torque. The present application can improve the torque control effect of the electric loader, and thus reduce the shaking and slipping phenomena of the electric loader caused by sudden changes in torque and speed.
