Abstract: Systems and methods for electronic pressure control of pumps in a dual pump system. The system may include a controller, a primary pump operated by the controller to maintain a system pressure in a flow path at a first pressure setpoint; a pressure transducer reading the system pressure and providing the system pressure to the controller; and a secondary pump operated by the controller to maintain the system pressure at a second pressure setpoint, the second pressure setpoint being less that the first pressure setpoint.

Abstract: A method controls the start-up of an oil pump of a gearbox by a brushless electric motor that has no position sensor. The stator coils are powered from the off mode in a constant-current open-loop control sequence until the pump reaches a speed threshold at which speed regulation switches over to closed-loop control on a setpoint corresponding to the lubrication flow rate required to ensure the reliability of the gearbox, but without in so doing exceeding a current threshold indicative of pump seizure, at which point motor control switches back over to the constant-current open-loop control sequence. The open-loop current setpoint is higher than the threshold for switching over to closed-loop control so that in the open-loop control mode the motor torque available at the pump is higher than in the closed-loop control mode.

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.
