To provide a hybrid type construction machine in which work can be kept on even if the amount of electricity stored in an electric storage device is out of an appropriate value. Both a hydraulic motor 27 and an electric motor 25 are provided for driving an upper swing structure 20. When the amount of electricity stored in a capacitor 24 is appropriate, the upper swing structure 20 is driven by both the hydraulic motor 27 and the electric motor 25. When the amount of electricity stored in the capacitor 24 exceeds an appropriate value, the mode is changed over to a mode in which the upper swing structure 20 is driven only by the hydraulic motor 27, and an assist electric generation motor 23 is assist-driven or engine-driven to thereby rapidly return the amount of electricity stored in the capacitor 24 to an appropriate range. The capacity of the capacitor 24 can be reduced, and the amount of electricity stored in the capacitor can be managed without losing the operability of swing motion.

In a hybrid vehicle including a master power supply always connected to MG (Motor-Generator) during driving and a first slave power supply and a second slave power supply capable of switching of a connection state with MG during driving, ECU connects one of the first slave power supply and the second slave power supply (S102, S106) and executes EV driving control with the master power supply and one of the slave power supplies, until both of SOCs1 of the first slave power supply and SOCs2 of the second slave power supply drop below a threshold value (YES in S100, YES in S104). On the other hand, when both of SOCs1 and SOCs2 drop below the threshold value (NO in S104), ECU disconnects both of the first slave power supply and the second slave power supply (S114) and executes HV driving control only with the master power supply (S116).

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.
