Provided is a hybrid-type work vehicle having excellent fuel economy performance. The work vehicle includes a power transmission device, a forward/backward travel switch operation device, a vehicle speed detection unit, and a control unit. The power transmission device includes a generator, a motor, and an energy storage unit. The energy storage unit stores electricity generated by the generator. The forward/backward travel switch operation device receives an instruction for forward or backward travel from an operator. The vehicle speed detection unit detects the speed of the vehicle. The control unit, which controls the power transmission device, includes an energy management requirement determination unit. The energy management requirement determination unit determines, on the basis of the difference between a target electricity storage amount and a current electricity storage amount in the energy storage unit, the energy management required power required by the power transmission device for charging the energy storage unit. The energy management requirement determination unit increases the target electricity storage amount when a first travel direction according to the instruction from the operator and a second travel direction determined from the vehicle speed are different. |
