摘要： A vehicle transmission includes a hydraulic circuit and a control unit. The control unit is configured to: obtain (20) a target pressure specification; convert (26) the target pressure specification into a target volume flow rate; determine (42) a valve volume flow rate as a function of the target volume flow rate and as a function of parameters that represent system properties of the hydraulic circuit; determine (46) a pressure drop at a valve due to flow forces as a function of the valve volume flow rate; determine (48) a compensated valve output pressure as a function of the valve volume flow rate and the pressure drop; determine (58) the electric control current as a function of the compensated valve output pressure; and activate a valve with the electric control current.

摘要： A coupling device for a motor vehicle includes a first coupling element associated with a first rotatable part of the motor vehicle, and a second coupling element associated with a second rotatable part of the motor vehicle. The coupling device moves one or both of the first coupling element and the second coupling element into an intermediate position before a target rotational speed differential between the first and the second coupling elements is reached. Specifically, the target rotational speed differential is reached before the coupling device moves the first coupling element and the second coupling element into form-lockingly coupling to couple the first and second rotatable parts.

摘要： A method for terminating a gearshift for an automatic transmission for a motor vehicle is provided, wherein a positive-locking shifting element is involved. After the initiation of the gearshift, there is an evaluation of the continuous signals of at least one control unit of the vehicle, which affect the engine torque and thus the turbine speed gradient. Based on the evaluation of the signals, an upcoming change to the turbine speed gradient that exceeds a first predetermined threshold value or falls short of a second predetermined threshold value is detected, and, upon such detection, the gearshift is terminated.

摘要： A method for operating an automatic transmission includes shifting the automatic transmission to a substitute gear if, after adjusting a first one of at least one positive-locking shift element towards a closed configuration, the first one of the at least one positive-locking shift element occupies an intermediate position. The first one of the at least one positive-locking shift element does not participate in the transmission of power in the substitute gear. A related transmission control device for an automatic transmission is also provided.

摘要： A method of engaging a form-interlocking shifting element to obtain a gear in an automatic transmission in which at least one further, frictional shifting element is involved in obtaining the gear to be engaged and a shifting element, not involved in obtaining the gear to be engaged but which serves as a synchronizing shifting element, is actuated in order to synchronize the interlocking shifting element to be engaged. The further, frictional shifting element, involved in engaging the gear, is engaged and then disengaged, to a defined extent, to bring the frictional shifting element to a slipping condition, in order to ensure the engagement of the interlocking shifting element.

摘要： The present subject matter provides a method for operating an automatic transmission in a limp mode. The method includes actuating a first non-positive shifting element to an engaged configuration and actuating a second non-positive shifting element to the engaged configuration. A positive shifting element is substantially synchronized after actuating the second non-positive shifting element. The method also includes commanding the positive shifting element to actuate from a disengaged configuration to the engaged configuration.

摘要： A method for operating a transmission (3) is provided, which includes a hydraulic pump drivable on a transmission-input end and at least one form-locking shift element (A, F). One of the shift-element halves is displaceable between a first end position and a second end position with a hydraulic pressure of the hydraulic pump. The current position of the shift-element half is detected with a sensor and is stored as a specified end-position value if the shift-element half is located in one of the end positions, the hydraulic pump is driven, and the shift-element half is actuated, with the hydraulic pressure, towards the current end position. When the hydraulic pressure is less than a threshold value, a deviation is determined between the current position of the shift-element half and the specified end-position value. The hydraulic pressure is increased when the deviation is greater than a threshold value.
