摘要： A method of operating a vehicle drive train having a drive machine, a transmission apparatus having a plurality of shift elements and an output drive. The plurality of shift elements are engaged or disengaged in a power flow for achieving different transmission ratios within the transmission apparatus. The output drive is coupled to a transmission output shaft and the drive machine is coupled to a transmission input shaft of the transmission apparatus. Upon a request to interrupt power flow within the transmission apparatus, between the transmission input shaft and the transmission output shaft, a maximum number of shift elements are transferred to and/or held in an engaged operating state, and the remaining portion of the shift elements are transferred to and/or held in a disengaged operating state with the transmission output shaft being rotatable.

摘要： A hydraulic system for actuating a transmission shifting element that comprises control and shifting valves. A first surface of a valve slide of the control valve is a differential surface between two functional surfaces of the slide that axially bound an area of the slide having a smaller diameter, by which the actuation pressure is adjusted. When the shifting valve is in a second switch position, a total force component acts upon the slide of the control valve which moves the slide such that the actuation pressure is equal to a system pressure. The total force component corresponds at least to the sum of a first force component equivalent to a pressure signal applied to a second surface of the slide of the control valve and a second force component equivalent to an actuation pressure applied to the first surface of the slide of the control valve.

摘要： A method of determining a fill current value of at least one frictionally engaging shift element of an automatic transmission. The automatic transmission includes a hydrodynamic converter at which a speed ratio arises and an output shaft. In a control sequence, with a stationary output shaft, the speed ratio is influenced by changing a control current, and the fill current value is determined from the progression of the speed ratio arising during the control sequence, in conjunction with the progression of the control current.

摘要： Description of a hydraulic control system (1A) for a hydrodynamic torque converter (1) with a controlled torque converter lockup clutch (2) of an automatic transmission for controlling a supply pressure (p_WD_zu) of the torque converter (2) and a supply pressure (p_WK_zu) of the torque converter lockup clutch (2). The torque converter lockup clutch (2) is engaged when the supply pressure (p_WD_zu) of the torque converter (1) is lower than a predefined pressure level of the supply pressure (p_WK_zu) of the torque converter lockup clutch. A converter pressure valve (WDV) is provided for controlling the supply pressure (p_WD_zu) of the torque converter (1), and a converter coupling valve (WKV) for controlling the supply pressure (p_WK_zu) of the torque converter lockup clutch, where their valve slides (WDV_S, WKV_S) can be acted upon by at least one pre-control pressure (p_VS) and one system pressure (p_sys). When the torque converter lockup clutch (2) is disengaged, the valve slide (WKV_S) of the converter coupling valve (WKV) is acted upon in such a way on an active surface (15) by the reverse pressure (p_WD_ab) of the torque converter (1), and when the torque converter lockup clutch (2) is engaged, is acted upon in such a way on the active surface (15) by the reverse pressure (p_WK_zu) of the torque converter lockup clutch (2), that at least either the supply pressure (p_WD_zu) of the torque converter (1) or the supply pressure (p_WK_zu) of the torque converter lockup clutch (2) is higher than a predefined pressure level (p—0) over the entire operational area of the torque converter (1).

摘要： A transmission device (1) with a hydraulic system (4) comprising a main transmission pump device for supplying various transmission components with hydraulic fluid. The main transmission pump device is driven by torque applied to the transmission input shaft (2). A force flow between the transmission input shaft (2) and transmission output shaft (3) is produced by various hydraulically actuated transmission components. When the hydraulic system (4) is not supplied by the main transmission pump, the force flow is interrupted. The hydraulic system (4) has an auxiliary pump device (5) by virtue of which the hydraulic system (4) too can be supplied with hydraulic fluid. The auxiliary pump device (5) is driven by torque applied to the transmission output shaft (3) at least when the force flow is interrupted.

摘要： An actuating mechanism (1) for operating a parking-lock mechanism of the drive chain of a vehicle with an automatic drive. The actuating mechanism has a piston unit (4), a detent element and an electromagnetic operating device (6) for operating a release element (7), which is intended for deactivating the detent element (5). The piston unit communicates with an emergency unlocking mechanism (14) and is positioned to open the locking mechanism by way of the piston unit. The detent element, the piston unit and the release element interact such that the locking mechanism remains in the currently engaged state when the locking mechanism is open and the operating device is not electrified, as well as when the locking mechanism is closed and a fluid pressure is applied to the piston unit.
