To provide a working vehicle, and a control device and a control method of the working vehicle which enables an operator to easily acquire an arbitrary brake force.SOLUTION: A brake force function determination unit exhibits a relation between rotation number of an output shaft of variable transmission and request braking force, and determines at least one of offset and inclination with respect to the request braking force, of such a braking force function that the request braking force monotonously increases with respect to the rotation number so that the smaller the level number of speed level selection inputted to a tractive force indication device, the larger an absolute value of at least one of the offset and inclination becomes. A request braking force determination unit determines the request braking force based on the rotation number of the output shaft of the variable transmission and the braking force function.SELECTED DRAWING: Figure 8

    【課題】オペレータが任意の制動力を容易に得る。【解決手段】制動力関数決定部は、変速機の出力軸の回転数と要求制動力との関係を示し、回転数に対して要求制動力が単調増加する制動力関数の、要求制動力に対するオフセットおよび傾きの少なくとも一方を、牽引力指示装置に入力された速度段選択の段数が小さいほど、オフセットおよび傾きの少なくとも一方の絶対値が大きくなるように決定する。要求制動力決定部は、変速機の出力軸の回転数と制動力関数とに基づいて要求制動力を決定する。【選択図】図8
