摘要： When temperature is low, a low-temperature mode is selected, followed by the activation of the heating mode functionality 25a of a PCU 25. Specifically, the PCU 25 sets the ratio of energy recovered by a capacitor 23 to be equal to or greater than the largest value of the energy recovery ratios of the capacitor 23 in a normal mode (e.g., assist motor 22 : capacitor 23 = 2 : 8). Thus, more energy is stored on the capacitor 23 than in the normal mode, helping the capacitor 23 generates heat. As a result, the liquid temperature of the coolant is increased, and its viscosity is reduced accordingly. As above, the invention provides a simple cooling system to be mounted on a hybrid working machine, which is capable of preventing decreases in energy efficiency at low temperature.

摘要： An excavator (1) has a controller (26) capable of setting target torque of a rotation motor (18) in accordance with a speed deviation between target speed set in accordance with an operation amount of an operating lever (25) and actual rotation speed and is provided with an inverter (23) for detecting necessary torque for rotating an upper rotating body (3), the necessary torque being changed in accordance with a working state of the upper rotating body (3). The controller (26) calculates a correction amount which is increased as increasing the torque and subtracts the correction amount from the target speed so as to set new target speed. A controller (26) sets first target torque for driving the motor and second target torque for maintaining the upper rotating body (3) on the spot on the basis of the actual speed, and operates the motor in accordance with the torque which has a larger absolute value in the same direction as the first target torque among both the torque.

摘要： The present invention is to drive a hydraulic pump (12) and a generator motor (13) by an engine (10), to electrically charge a battery (20) by a generator action of the generator motor (13), and to drive the generator motor (13) by electric power of the battery (20) so as to assist the engine (10). A governor (26) position is changed by operations of a potentiometer for accelerator (21) and a mode selection (22) switch so as to control rotation speed of the engine (10). On the premise of the above configuration, generator (13) output is limited by a controller (16) at the time of accelerating the engine (10) until the rotation speed of the engine (10) reaches set speed determined on the basis of the operations of the potentiometer for accelerator (21) and the mode selection switch (22), and hence engine load is reduced so as to assist acceleration.

摘要： 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.

摘要： A first warming-up control unit calculates warming-up time charging power from a power storage SOC and power storage temperature and causes a generator motor (2) to perform power generation operation thereby charging a power storage unit (4) on the basis of the calculated warming-up time charging power. A second warming-up control unit applies, during the power generation operation, a hydraulic load to a hydraulic pump (5) by a hydraulic load unit (10, 11) and performs horsepower control of the hydraulic pump (5) using a value obtained by subtracting the warming-up time charging power from preset warming-up time pump horsepower.
