    摘要： A work vehicle includes a controller. The controller is configured to determine whether low-load conditions indicating that the work vehicle is in a low-load state are satisfied. The controller is configured to control an engine so that an upper limit value of an output torque of the engine when the low-load conditions are satisfied is made less than when the low-load conditions are not satisfied. Also, the controller is configured to vary a reduction amount of the upper limit value of the output torque of the engine when the low-load conditions are satisfied, in accordance with variation in at least one of vehicle speed, vehicle acceleration, and engine-rotation-speed acceleration, and in accordance with variation in engine rotation speed.
