    Abstract: A hydraulic control system is disclosed. The hydraulic control system may have a hydraulic actuator, a valve arrangement, and an operator input device configured to generate a first signal indicative of a desired hydraulic actuator velocity. The hydraulic control system may also have a sensor configured to generate a second signal indicative of an actual flow rate of fluid entering the hydraulic actuator, and a controller. The controller may be configured to determine a desired flow rate of fluid into the hydraulic actuator based on the first signal; to estimate the actual flow rate based on the desired flow rate, a correction flow rate, and a system response model; and to determine the actual flow rate based on the second signal. The controller may also be configured to make a comparison of the estimated and determined actual flow rates of fluid, and to determine the correction flow rate based on the comparison.

    Abstract: A control device for a hybrid construction machine includes a discharge pressure introduction passage that leads a discharge pressure from a variable volume pump to a regulator, and a load pressure introduction passage that leads one of a maximum load pressure of respective actuators and a load pressure of a hydraulic motor to the regulator. A controller, having determined that the actuators are in an inoperative condition on the basis of a detection result from an operating condition detector, excites a solenoid of a solenoid pilot control valve such that a discharge oil from the variable volume pump is led to the hydraulic motor, and controls the regulator such that a differential pressure between the discharge pressure of the variable volume pump and the load pressure of the hydraulic motor is kept constant.

    Abstract: A hybrid hydraulic drivetrain is configured to propel a vehicle and regenerate propulsion energy. The drivetrain includes a prime mover, an accumulator, an axle, a first rotating group, a second rotating group, and a hydraulic transformer. The first rotating group is configured to receive shaft energy from the prime mover, receive shaft energy from the drive axle, send shaft energy to the drive axle, receive hydraulic energy from the hydraulic accumulator, and send hydraulic energy to the accumulator. The second rotating group is configured to receive shaft energy from the prime mover. The hydraulic transformer is configured to charge the accumulator with hydraulic energy received from the second rotating group. The hydraulic transformer may be remotely mounted from the second rotating group. The second rotating group may supply hydraulic energy to an auxiliary circuit of the vehicle. The auxiliary circuit may operate with the prime mover shut down.

    Abstract: A hydraulic arrangement (10) to increase a motor load is described. The hydraulic arrangement comprises a hydraulic consumer (28), a load pressure-controlled hydraulic pump (24), a hydraulic tank (26), and a hydraulic control circuit (30), connected with the hydraulic consumer (28), with which a volume flow conveyed by the hydraulic pump (24) can be changed, wherein the hydraulic control circuit (30) comprises an excess pressure valve (42) and an electronically controllable control valve (36). In order to ensure a prioritization of the hydraulic consumer with a simultaneous increase of the motor bad, a proposal is made that the hydraulic control circuit (30) comprise a load pressure-controlled pressure compensator (38) between the excess pressure valve (42) and the control valve (36).
