摘要： Method for determining an adjustment parameter in a hydraulic actuator arrangement for a motor vehicle drivetrain. The actuator arrangement has a pump and a hydraulic cylinder. A pressure port of the pump is connected to a port of the hydraulic cylinder. The adjustment parameter is a function of the volume of the fluid that must be delivered by the pump in order to realize a predetermined operating point of the actuator arrangement. The operating point is defined by a value pair of an operating point rotational speed value of the pump and an operating point control value of the pump. The method has the steps: regulating the pump to the operating point rotational speed value such that the pump delivers a fluid volume flow rate corresponding to the operating point rotational speed value; and integrating the fluid volume flow rate over the time until a termination operating state of the actuator arrangement, in which the control value of the pump is less than or equal to the operating point control value.

摘要： A method of controlling a transmission is provided. A command is received to engage a clutch having a chamber. A control valve is opened to allow pressurized fluid to flow from a fluid supply line into the clutch chamber. The pressure of the fluid within the fluid supply line is monitored as fluid flows through the control valve to enter the clutch chamber. A rate of change in the volume of fluid entering the chamber is determined based on the sensed pressure of the fluid within the fluid supply line. A fill point of the clutch chamber is detected when the rate of change in the volume of fluid entering the chamber is less than a volume differential threshold.

摘要： A clutch cylinder in a hydraulic pressure system can be charged with a controlled rotational speed of a pump to deliver hydraulic fluid into the clutch cylinder until a biting point of the clutch is reached and exceeded and a motor current of the pump has attained a predetermined minimum value. On the basis of a profile of the controlled rotational speed, a first volume of the hydraulic fluid delivered into the clutch cylinder by the pump up is determined until the minimum value is attained. The value of the first volume can be reduced by a predetermined amount to a second volume, which can be used for clutch processes during vehicle operation, wherein the second volume is delivered into the clutch cylinder, with a high rotational speed of the pump, such that the clutch is filled such that the biting point of the clutch is not quite reached.

摘要： A clutch control device for vehicle equipped with a clutch actuator driven by a working fluid, wherein the rate of connection of the clutch is correctly controlled by using a simple means while compensating for secular changes in a flow rate control valve that controls the working fluid. To control the stroke of the clutch actuator 110, the clutch control device is provided with a single flow rate control valve 1 that controls the feed and discharge of the working fluid by using an electromagnetic solenoid. A flow rate control valve control device 9 is equipped with a learning device 91 that learns the neutral position of the flow rate control valve 1 to shut off the flow of the working fluid. At the time of learning, the learning device 91 renders the transmission to be neutral, executes the operation for increasing the stroke after the stroke is decreased, detects the rate of change in the stroke, and learns the central point at the neutral position. In controlling the stroke of the clutch, the amount of electric current to the coil 8 is adjusted based on the learned value to compensate for a change in the flow rate characteristics caused by secular change and the like.

摘要： The present invention provides an apparatus for controlling a hydraulic pressure usable for a clutch wherein the apparatus is employed for a transmission mounted on a construction machine or the like in such a manner that it is provided separately for a plurality of clutches and it is controlled individually. The apparatus includes a first valve for allowing a large amount of hydraulic oil to flow in the clutch and a second valve for electronically controlling a clutch pressure so that the termination of filling and the clutch pressure are detected by a simple structural arrangement on the basis of a displacement of a spool for the first valve and a separately disposed piston. In addition, appearing of an overshoot pressure on the termination of filling is prevented by providing a difference in pressure receiving areas on the spool for the first valve.

摘要： A hydraulic control system for controlling a variable fluid volume flow to a consumer (6, 60, 94, 126, 146, 162), for example a flow of cooling oil to a wet-operating clutch, with a hydraulically pilot-controlled control valve connected to a fluid supply. The first control valve (2, 56, 90, 122, 142) is designed such that, in the absence of any pilot control pressure (pVST), the valve delivers a specified initial volume flow (Q1) and, as the variable pilot control pressure (pVST) increases, the valve delivers a continuously increasing volume flow (QK). At least one second, independent, also hydraulically pilot-controlled valve (170) is designed such that this valve is activated in a specified range (55, 88, 120, 132, 140, 152) of the variable pilot control pressure (pVST).

To control the stroke of a clutch actuator 110, the clutch control device is provided with a single flow rate control valve 1 that controls the feed and discharge of the working fluid by using an electromagnetic solenoid. A flow rate control valve control device 9 is provided with a learning device 91 that learns the neutral position of the flow rate control valve 1 which shuts off the flow of the working fluid, separately detects the amounts of electric current to a coil 8 of when the rate of change in the stroke becomes zero depending upon the directions in which the valve body of the flow control valve 1 moves, and learns the central point at the neutral position by averaging the detected values. In controlling the stroke of the clutch, the amount of electric current to the coil 8 is corrected based on the learned value to compensate for a change in the flow rate characteristics by secular changes.
