Abstract
A traction force control section of a wheel loader, when the determination conditions are satisfied during traction force control, increases the maximum traction force. The determination conditions include that the wheel loader is performing an excavation operation, that the vehicle speed is less than or equal to a prescribed speed threshold value, that the amount of operation of the accelerator operating member is equal to or more than a prescribed accelerator threshold value, and that the amount of operation of the inching operating member is less than or equal to a prescribed inching operation threshold value.
