Work Vehicle

A work vehicle comprising:

• an engine;
• a generator motor for generating electric power by operating on drive power of the engine;
• an electric motor operating on electric power supplied from the generator motor;
• drive wheels rotating with drive power of the electric motor transmitted thereto;
• a hydraulic pump for force feeding hydraulic oil by operating on the drive power transmitted from the engine or the generator motor operating as a motor;
• a hydraulic actuator operating on the hydraulic oil supplied from the hydraulic pump;
• a throttle device for actuating an exhaust brake as disposed at a tube exhaust duct of the engine;
• and a controller for controlling operations of the generator motor and the throttle device,
• wherein the controller
• calculates a regenerative power outputted from the electric motor and a target hydraulic driving power for driving the hydraulic pump,
• supplies the regenerative power to the generator motor operating as the motor and makes the generator motor consume the regenerative power in a case where the regenerative power is equal to or smaller than the target hydraulic driving power, and
• supplies the regenerative power to the generator motor operating as the motor and makes the exhaust brake consume a power equivalent to a difference between the regenerative power and the target hydraulic driving power in a case where the regenerative power is larger than the target hydraulic driving power.
