  "textContent": "An objective of the present invention is to inhibit an increase in vehicle speed immediately after a lockup clutch has been switched from a non-connected state to a connected state, and to improve fuel economy. In a work vehicle, a controller controls an engine on the basis of an engine torque curve for defining a relationship between the engine speed, the engine output torque, and the operation amount of the accelerator operation member. The controller controls the engine on the basis of a first engine torque curve during torque conversion travel. The controller controls the engine on the basis of a second engine torque curve during lockup travel. The engine output torque of the second engine torque curve is less than the engine output torque of the first engine torque curve in at least a portion of the range of the engine speed when at least the operation amount of the accelerator operation member is a predetermined operation amount that is less than maximum.",
