Embodiment Construction

[0021] figure 1 A drive train of a vehicle is shown schematically, wherein the drive train has a controller 4 according to an exemplary embodiment of the invention. The controller 4 acts on the clutch 1 , wherein the clutch 1 is arranged between the drive motor 2 and the transmission 3 in order to selectively enable or prevent a torque transmission between the drive motor 2 and the transmission 3 . The clutch 1 thus comprises a transmission-side part and a motor-side part which are fixedly connected to the transmission 3 or the drive motor 2 respectively and which Can be selectively attached or detached. The transmission 3 is connected to the wheels 5 of the vehicle so as to drive the vehicle through the wheels 5 .

[0022] The clutch 1 is in particular an electronically operated clutch which can be actuated by a driver of the vehicle via a clutch pedal. The clutch pedal is provided in particular to transmit control commands to the controller 4 for actuating the clutch 1 . ...

Abstract

The present invention relates to a method for driving a clutch (1), wherein the clutch (1) is arrangeable between a drive motor (2) and a transmission (3) to selectively enable or prevent transmission of rotational energy, comprising the steps By detecting (100) that the clutch (1) has been disengaged, predicting (400) a new gear in which the transmission (3) will be shifted, estimating (500) a speed of the transmission (3) with a predicted new gear engaged , Adjusting a rotational speed of the drive motor (2) in dependence on the estimated rotational speed of the transmission (3), and decelerating (700) engagement of the clutch (1) for adjusting the rotational speeds of the drive motor (2) and the transmission (3).

Description

technical field [0001] The invention relates to a method for actuating a clutch. Furthermore, the invention relates to a computer program product and a controller for implementing such a method. Background technique [0002] Clutches installed in vehicles are known from the prior art. Such a clutch is used to break or establish a connection between the engine and the transmission, via which torque can be transmitted. If the gear of the transmission is to be changed, the clutch is disengaged, the gear is changed and then the clutch is engaged. However, if the engagement process is carried out too quickly, a sudden compensation of the rotational speeds of the engine and the transmission occurs, which can be noticed in the interior of the vehicle as shift shocks. Such shocks are uncomfortable for the occupants of the vehicle and are therefore to be avoided. [0003] Furthermore, it is known from the prior art to install a shift assist assistant, by means of which the aforem...
