摘要: In a working vehicle, a control unit is configured to control an engine based on an engine power curve indicating a relationship between an engine speed and an engine output torque. The control unit is further configured to calculate an absorption horsepower that is an absorption horsepower of a hydraulic pump and to change the engine power curve used to control the engine based on the absorption horsepower.
