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： A power transmission includes first and second clutches for switching a transmission path for a driving force therein. A clutch controlling unit provided for a work vehicle is configured to switch the transmission path from one to the other of first and second modes when a speed ratio parameter reaches a mode switching threshold. The clutch controlling unit is configured to keep setting the transmission path in the other mode even when the speed ratio parameter again reaches the mode switching threshold until a switching prohibition period having a predetermined initial value expires as long as a period of time elapsed after mode switching is included in the switching prohibition period. A trigger detecting unit provided for the work vehicle is configured to make the switching prohibition period expire when detecting a predetermined operation in the switching prohibition period.

摘要： A speed change control apparatus (30) for a work vehicle (1) includes a hydraulic continuously variable speed transmission (8) that performs speed change on power input from an engine (7) by changing a trunnion shaft angle based on a depressing amount of a speed change pedal (22) and outputs the power, a pedal position detector (321) that detects a pedal position responsive to the depressing amount of the speed change pedal (22), and a control unit (32) that controls a number of revolutions of the engine (7) and the trunnion shaft angle of the hydraulic continuously variable speed transmission (8) based on a detection value of the pedal position detector (321). The control unit (32) performs control so that the trunnion shaft angle is maximized at a second pedal position (P2) set to a position shallower than a first pedal position (P1) at which the number of revolutions of the engine (7) is maximized by a depressing operation of the speed change pedal (22).
