A method of adapting control of clutches of a double clutch transmission, including: during a shifting process, controlling torque transmittable by an opening clutch and torque transmittable by a closing clutch according to nominal curves; during a shifting process, determining a difference between a nominal value and an actual value; and adapting a nominal curve of at least one of the clutches for a following shifting process by reducing a difference between the nominal value and the actual value.

A pump drive system having a pump drive element that is driven by a first or a second drive mechanism. The pump drive element is connectable or connected by a coupling element in a rotationally fixed connection either through a first free-wheel device to the first drive mechanism or through a second free-wheel device to the second drive mechanism.

Pump drive system

A method is described for controlling a clutch which is located between a drive motor and an automated manual transmission of a drive train. In this method, vibrations during load alternations are reduced by controlling the clutch so that a free-wheeling function is implemented during an engine braking mode.

Method for controlling a clutch

A method is proposed for triggering the clutch moment of a clutch of an automated gear in the power train of a vehicle with the creep function activated, where the clutch moment is triggered as a function of the slippage on the clutch and/or as a function of the speed of the vehicle. Furthermore, a device is proposed for triggering the clutch moment of a clutch of an automated gear, in particular, to implement the abovementioned method where at least one control device is provided which triggers the clutch moment as a function of the slippage on the clutch and/or as a function of the speed of the vehicle.

A method for diagnosing damage in the shift control actuator of an automated manual transmission, involving at least one of the following steps: (a) determining a shift control actuator is damaged if an actual period needed for synchronizing a gear differs from a nominal time period for synchronizing the gear; (b) moving a shift-control actuator to a limit stop after selection of a gear, and determining a shift-control actuator is damaged if the limit stop that has been reached is an internal limit stop of the shift-control actuator and not a gear transmission limit stop; (c) determining the shift-control actuator is damaged if an actual speed during the overlap phase is not within a speed range within which the engine speed is expected to lie during the overlap phase.

Method for detecting damage in the shift-control actuator of an automated manual transmission

A method for the adjustment of a gearbox actuation system of an automated gearbox of a vehicle. The gearbox includes a shift finger; a plurality of gearshift rails, each rail in the plurality of gearshift rails in a respective position; a neutral gap with a first portion formed by respective jaws for said each rail and with a second portion formed separate from the respective jaws and open to the first portion; and, a gearshift motor. The method includes the step of performing at least one reference travel with a gear in the automated gearbox engaged.

The invention relates to a method for adjusting the gearbox actuation system of an automatic gearbox of a vehicle, whereby at least one reference travel is made with the gear engaged. The invention further relates to a gearbox actuation system for selecting and engaging gears in an automatic gearbox of a vehicle, especially for carrying out the inventive method, whereby at least one reference travel is made for the purpose of adjustment.

The invention relates to a method and device for securely and comfortably operating a drive train of a motor vehicle, especially for operating a drive train with several clutches.

Method and system for controlling at least one actuator in the drive train of a motor vehicle

A method of controlling a twin-clutch transmission with a first partial transmission with which are associated a first engine clutch and a first group of gears, and a second partial transmission with which are associated a second engine clutch and a second group of gears, said method containing the step of engaging a forward gear associated with one partial transmission and a reverse gear associated with the other partial transmission when the transmission, with the motor vehicle at a standstill, is in a non-driving position.

Method for controlling a twin-clutch transmission

Methods and devices for actuating a parking brake in a gearbox which is actuated in an automated manner, whereby gear changes are carried out using at least one electrically driven actuator, gear positions can be selected by using a selector device, and the parking brake can be activated by using the selector device when the vehicle is stationary or moving slowly. A vehicle provided with an additional gearbox. An ignition key can only be removed, when the gearbox is in a P state and the additional gearbox is not in the N state. A further method and device, whereby the additional gearbox can only be shifted in the N state when the gearbox is not in the P state. Further methods and a device in which automated manual gearboxes, especially parallel gearboxes, are controlled in such a way that the vehicle can be safely parked.

Method and device for operating especially an automatic or automated gearbox comprising a parking brake and a runaway locking mechanism

A method for controlling gear-shifting processes of a powershift gearbox which can be coupled to a drive motor and has gear steps including two friction clutches and a plurality of clutches, and at least one gearbox actuator for actuating the gear steps. The method includes the following steps: the torque of the drive motor is received by the new friction clutch associated with the new gear step to be engaged; before the disengagement of the old gear step and before or during the torque reception, a pre-determined pre-tensioning force is applied to the clutch of the old gear step by the gearbox actuator; and the old gear step is disengaged when the motor torque and the clutch torque are balanced.

Actuation devices are disclosed for a pressure-closed clutch where the position of an actuation member is acquired by an incremental sensor. In an embodiment of the actuation device, the signal of the incremental sensor is acquired in case of a sudden change in the power consumption of an actuator and is used as a new reference signal. In another embodiment, the actuation member, while the spindle is rotating, is moved by a recovery spring during the closing of the clutch against a stop and the signal of the incremental sensor upon the attainment of said stop is used as a reference signal.
