摘要： A system and method are provided for monitoring a vehicle hydraulic system having a plurality of hydraulic function elements (50, 52, 54, 60, 62, 70). The hydraulic system includes a hydraulic pump (12) for supplying pressurized hydraulic fluid to the plurality of hydraulic function elements (50, 52, 54, 60, 62, 70) via a corresponding plurality of hydraulic element control valves (16,20), an electronic control unit (40) for controlling the element control valves (16,20). The pump (12) also supplies lube fluid to a lubrication circuit if requirements of the hydraulic function elements (50, 52, 54, 60, 62, 70) are met. The method includes sensing a hydraulic pressure, and comparing the sensed pressure to a threshold pressure. If the sensed pressure is less than threshold pressure, then actively engaged hydraulic elements (50, 52, 54, 60, 62, 70) are tested by disengaging the elements (50, 52, 54, 60, 62, 70) in a predetermined manner, checking to see if the sensed low pressure condition is eliminated. If the sensed low pressure condition is eliminated after disengaging an element, then the leaking hydraulic function element is deactivated.

摘要： This control system (100), for controlling an oil level in a gearbox of a vehicle, comprises a supply line (102), which is configured to be connected to a pressurized upstream oil supply (54) of the gearbox, a return line (104), a first valve (106) and a second valve (108). The first and second valves are respectively controlled by a first fork (48A) and a second fork (48B) of the gearbox. The return line is connected to the supply line through the first valve and the second valve, which are arranged in serial, the first and second valves being both in the open position when the first and second forks are together in a direct drive configuration that engages a direct drive gear selection of the gearbox, so that the return line is pressurized when both valves are open and when the supply line is pressurized. The control system comprises a flow control unit (112), which is configured to lower the oil level in an oil sump of the gearbox when the return line is pressurized.

摘要： A hydraulic system (1) of a transmission device (2) is connected to a hydraulic pump (43) which can be driven via a transmission input shaft and to a further hydraulic pump (44) which can be driven via a transmission shaft, and conducts hydraulic fluid volumes, which are delivered by the hydraulic pumps (43, 44), to transmission components. Hydraulic fluid can be applied to transmission components via a primary pressure circuit (46) and via a secondary pressure circuit (54). A pressure side (45) of the hydraulic pump (43) is coupled directly to the primary pressure circuit (46) and can be connected to the secondary pressure circuit (54) via the system pressure valve (47). A pressure side (64) of the further hydraulic pump (44) is connected directly to the secondary pressure circuit (54). The pressure side (45) of the hydraulic pump (44) can be connected in the region of the secondary pressure circuit (54) via a valve device (48) to a transmission component configured as a wheelset and to a transmission component configured as a dual clutch system (56) and also to an intake region (69) of the hydraulic pumps (43, 44). The pressure side (64) of the further hydraulic pump (44) is connected to the wheelset and can be coupled to the dual clutch system (56) via the valve device (48).

摘要： The present disclosure provides a hydraulic system of a transmission having a controller and a variable displacement pump. The pump includes an inlet and outlet and is adapted to be driven by a torque-generating mechanism. The system also includes a lube circuit fluidly coupled to the pump. A lube regulator valve is disposed in the lube circuit, such that the lube regulator valve is configured to move between at least a regulated position and an unregulated position. The regulated position corresponds to a regulated pressure in the lube circuit. A pressure switch is fluidly coupled to the lube regulator valve and configured to move between a first position and a second position, where the switch is disposed in electrical communication with the controller. A solenoid is disposed in electrical communication with the controller and is controllably coupled to the pump to alter the displacement of the pump.
