Abstract: A hydraulic working machine is provided which has an assist electric motor connected to an engine and a hydraulic pump, the hydraulic working machine being structured in such a manner that the emissions of air pollutants in the exhaust gas from the engine are minimized regardless of fluctuations in the load torque of the hydraulic pump, that the increasing cost of installing an exhaust gas after-treatment device is lowered, and that the reliability of the engine is enhanced. A specific revolution speed suitable for reducing the emissions of air pollutants is stored, and an engine (7) is controlled using the specific revolution speed as a target revolution speed for the engine. The absorption torque of a hydraulic pump (6) is subjected to a high-pass filtering process whereby a high-frequency component devoid of a trend component is obtained. Target assist torque is computed from the high-frequency component, and an assist electric motor (10) is subjected to power running/generation control accordingly. A specific output torque range suitable for reducing the emissions of air pollutants is stored, and the target assist torque is corrected so that the trend component does not exceed the specific output torque range.

Abstract: A hybrid working vehicle (1) comprises an engine (3), a drive wheel (7), a power take-off (PTO) shaft (11), and a power transmission system for transmitting power from the engine (3) to the drive wheel (7) and the PTO shaft (11). The power transmission system is bifurcated at a bifurcating point (24, 39) into a traveling drive train (52) for driving the drive wheel (7) and a PTO drive train (53) for driving the PTO shaft (11). A continuously variable transmission (14) is provided on the traveling drive train (52), and a motor generator (4) is provided on the power transmission system between the engine (3) and the bifurcating point (24, 39). The motor generator (4) functions as a generator by power of the engine (3) and functions as an electric motor for driving the power transmission system. The hybrid working vehicle (1) includes a controller (100) for controlling an output rotary speed of the motor generator (4) functioning as the electric motor.

Abstract: A method includes measuring a parameter indicative of a measured torque in a PTO clutch (60), determining an incremental torque based at least in part on proportional-integral-derivative (PID) control logic, determining a command torque, wherein the command torque is a sum of the measured torque and the incremental torque, generating a control signal, wherein a current of the control signal corresponds to the command torque and a pressure in a cylinder (106) of the PTO clutch (60), providing the control signal to the PTO clutch (60), reducing the incremental torque if an engagement power exceeds an engine power output, and ceasing engagement if an energy absorbed by the clutch exceeds an energy rating of the PTO clutch (60).
