摘要： A control system for a work vehicle includes a temperature detecting unit and a controller. The temperature detecting unit detects the temperature of the electrical drive system. The controller controls the output of an electric motor when the temperature of the electrical drive system detected by the temperature detecting unit exceeds a predetermined first threshold and an operating member of the movable body is positioned in a neutral position. The controller does not limit the output of the electric motor when the operating member for the movable body is being operated even when the temperature of the electrical drive system exceeds the first threshold.

摘要： Two sets of assemblies are arranged such that a diesel particulate filter device of the assembly, a selective catalytic reduction device of the assembly, a selective catalytic reduction device of the assembly, and a diesel particulate filter device of the assembly are located next to each other in this order. Exhaust tubes are provided to extend upward from gas outlets of the selective catalytic reduction device of the assembly and the selective catalytic reduction device of the assembly. The two exhaust tubes are located on a virtual plane orthogonal to longitudinal directions of the selective catalytic reduction devices of the assemblies. Thereby, an air intake position for an engine can be easily set to a position from which exhaust gas from the engine is less likely to be taken in, in a configuration provided with two sets of assemblies.

摘要： A hydraulic working machine has an assist electric motor connected to an engine and a hydraulic pump. 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. A specific revolution speed suitable for reducing the emissions of air pollutants is stored, and an engine is controlled using the specific revolution speed as a target revolution speed. The absorption torque of a hydraulic pump is subjected to high-pass filtering whereby a high-frequency component devoid of a trend component is obtained. Target assist torque is computed from the high-frequency component, and the assist electric motor 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.
