Embodiment Construction

[0017] Refer below figure 1 and 2 A preferred electrically actuatable clutch system 1 of a vehicle is described in detail.

[0018] as available from figure 1 As seen in the figure, the clutch system 1 includes a clutch 2 and a clutch pedal 3 . A first position sensor 4 is provided for determining the position of clutch pedal 3 . The clutch pedal 3 is supported by a spring 5 for applying resistance to the driver when actuating the clutch pedal so as to give a real clutch pedal feel.

[0019] The first position sensor 4 is connected to a control unit 6 which is itself connected to an electric motor 7 .

[0020] The electric motor 7 is a part of the electro-hydraulic mechanism 10, and the electro-hydraulic mechanism includes a control cylinder 11, an output cylinder or an energy storage cylinder 12, and a hydraulic circuit 15 extending between the control cylinder 11 and the output cylinder 13 . Furthermore, a second position sensor 8 is arranged on the electric motor 7 . ...

Abstract

The invention relates to a method for executing a reference run of an electrically-operating-capable clutch assembly (1) comprising a clutch pedal (3) and a first position sensor (4) for detecting a position of the clutch pedal (3), comprising the steps of determining a position of the clutch pedal (3) and performing a homing to determine a reference point in dependence of the position of the clutch pedal (3). The invention further relates to a corresponding electrically-operating-capable clutch assembly.

Description

technical field [0001] The invention relates to a method for carrying out a reference operation of an electrically actuated clutch system of a vehicle and a corresponding electrically actuated clutch system (clutch-by-wire-anordnung). Background technique [0002] Recently, so-called electrically actuatable clutch systems (clutch-by-wire) are increasingly being used in vehicles, for example in combination with dual-clutch transmissions. In order to reduce emissions, several strategies have also been developed in the field of vehicles, such as automatically switching off the vehicle engine when the vehicle is only rolling or is idling. So-called start-stop systems are also known. However, these technologies require the engine to be separated from the wheels, which is achieved by disengaging the clutch. In an electrically actuatable clutch system, an electric drive is used for disengaging the clutch. In order to be able to reliably disengage the clutch, the absolute positio...
