Abstract: A work implement requirement determination unit of a work vehicle determines a work implement required power based on the operation amount of a work implement operating member and the work implement pump pressure. A transmission requirement determination unit determines a transmission required power based on the vehicle speed and the operation amount of the accelerator operating member. When the sum of the work implement required power and the transmission required power is greater than a first distributable power that a predetermined preferential distribution power subtracted from a load upper limit power of the engine leaves, a distribution ratio determination unit allocates the smaller of a transmission compensation power and the transmission required power to a power transmission device and distributes the remainder of the first distributable power to the work implement pump and to a power transmission device.

Abstract: A target-input-torque determination unit determines the target input torque on the basis of the transmission required horsepower. The target input torque is a target value for the torque to be inputted to a power-transmission device. A target-output-torque determination unit determines the target output torque, which is a target value for the torque to be outputted by the power-transmission device. A command-torque determination unit uses torque-balance information to determine command torque for the motor from the target input torque and the target output torque. The target-input-torque determination unit determines the upper limit of the target input torque on the basis of an upper-limit-target-input-torque line and the engine rotation speed. The upper-limit-target-input-torque line sets a value smaller than the target output torque of the engine determined using the engine required horsepower and the engine rotation speed for the upper-limit value of the target input torque.

Abstract: A construction machine hydraulic drive system that performs load sensing control is capable of efficiently burning and removing deposits on a filter in an exhaust gas purifying device through pump output increasing control and to be free from faults in the pump output increasing control even when an actuator is operated during the pump output increasing control. A solenoid switching valve is switched so that output pressure of an engine speed detecting valve is guided to a pressure receiving portion of an LS control valve and a pressure receiving portion of an unloading valve when a start of regeneration is not directed, and delivery pressure of a pilot pump is guided to the pressure receiving portion and the pressure receiving portion when the start of the regeneration is directed, to thereby disable load sensing control to increase capacity of a main pump and increase set pressure of the unloading valve.

Abstract: A control device is configured to sufficiently reduce the drive loss of a hydraulic pump. The control device is provided with a controller configured to control a regeneration valve to switch to a regeneration state, and to control the flow rate of a second hydraulic pump to reduce the ejection flow rate of the second hydraulic pump in accordance with regeneration of hydraulic oil through the regeneration valve when a combined operation of lowering a boom and pressing an arm is performed. The controller outputs a command for setting the number of rotations of an engine to be smaller than the rotation number designated by a rotation number designating unit when the ejection flow rate of the second hydraulic pump is not larger than a predetermined flow rate during the combined operation.

Abstract: An engine control system for a working machine measures the sulfur content of an exhaust gas since sulfur is detrimental to normal functioning of an exhaust gas aftertreatment device. Each time a key switch is turned ON to start an engine, the engine control system compares a remaining fuel amount memorized at the last stop of the engine and a remaining fuel amount detected at the current start of the engine. The engine control system performs a sulfur concentration measurement process only when the remaining fuel amount is increased. A target revolution speed Na appropriate for measuring the concentration of sulfur is set and when the temperature of the exhaust gas is within a predetermined temperature range and a target time has elapsed, the engine control system determines whether the sulfur concentration exceeds a threshold value. If the sulfur concentration exceeds the threshold value, an alarm display device is activated.
