Wheel loaders are used to scoop up earth and sand generated at construction sites and load it onto dump trucks. If the amount of earth and sand scooped up is larger than the weight limit of the dump truck, the amount of earth and sand must be fine-tuned before being loaded into the dump truck inefficiently. Therefore, our laboratory has been studying methods to control the amount of earth and sand while scooping it up. However, the method proposed in previous studies required a traction force so large that it was impossible to realize. To solve this problem, we newly proposed with traction force control method. The new traction force control method was based on the actual movement of a wheel loader. Then, we proposed an earthwork volume control method. The new control method is expected to be able to control the amount of earthwork volume with an accuracy of less than 1% error. To prevent changes in earth and sand properties due to weather conditions, numerical simulations were used in this study.
