Abstract: A method of controlling a hydraulic system having a variable displacement pump operatively coupled to an engine. The method includes detecting a speed of the engine, and determining a desired power value of the pump. The method also includes identifying an allowable power value that may be expended by the pump at the detected speed. The method also includes selecting a pump power value. The selected pump power value is the lower of the allowable power value and the desired power value. The method further includes adjusting the pump to deliver the selected pump power value.

Abstract: An air compressor comprising: a tank (50), a compression mechanism (30), a motor (5) and a control circuit (7). The control circuit (7) includes a CPU (70) and a storing unit (74) which stores a control program, the compressor operation history and a plurality of operation modes. Each of the operation modes is defined by two setting values: a reference restart pressure value and a motor rotational speed value, at least one of these values being different from among the plurality of modes. The control circuit (7) executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the pressure in the tank with the reference restart pressure and rotates the motor at the rotational speed of the target mode. The control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the compressor operation history.

Abstract: An electric oil pump for supplying oil to at least a part (a clutch) of a transmission is provided in parallel with a mechanical oil pump which is driven by an engine and supplies oil to each part of the transmission. In advance of an operation request to the electric oil pump, the electric oil pump is rotated at a first operation-preparation rotational speed which is a very low speed so as to replace oils in oil pipes controlled by the electric oil pump. Thereafter, the electric oil pump is rotated at a second operation-preparation rotational speed which is a relatively-high speed, and when an actual rotational speed reaches the second operation-preparation rotational speed, it is determined that operation preparation is completed.

Abstract: Air-demand-controlled compressor arrangement, particularly for commercial vehicles, includes a motor unit for generating a rotating movement which, by way of an interposed rotational-speed-transmitting transmission unit, drives a compressor unit for generating compressed air from ambient air. A control unit triggers the generating of compressed air in the case of a compressed-air demand. The transmission unit is constructed in the manner of a transmission whose rotational speed can be varied, and the control unit interacts with the transmission unit in order to adapt the rotational speed of the transmission unit corresponding to the compressed-air demand.
