摘要:
The invention relates to a clutch (3) which is actuated and deactuated by an actuator, the position of which is controlled by a regulating loop. Said clutch is brought into a position by a regulator (32) at the beginning of a shift procedure, wherein the revolution speed of the gearbox input shaft (31) when a gear is disengaged corresponds to a predefined proportion of the target revolution speed of the gear box input shaft whensaid gear is engaged. The determined position is used as a contact point for the actual shift procedure.

A clutch control apparatus comprises a flywheel (10a) integrally rotated with an output shaft of a driving power source (10), an automatic clutch (20) having a clutch disc (21a) arranged facing the flywheel (10a). The clutch control apparatus does not perform a learning control to determine a stand-by position of the clutch disc at the start point of the driving power source (10) when a driving power source start condition is satisfied in a state where the clutch disc (21 a) has been engaged with a flywheel (10a) so as to perform a torque transmission between the flywheel (10a) and the clutch disc (21a).

A pressure control device is used to affect the closing behaviour of power shift clutches in a power shift gear with a control valve co-operating with a damping device as the pressure control valve (2) by means of which the pressure cycle can be set on engaging the clutch concerned. The pressure in a chamber (C3) between a displacement piston (4) and a pressure control piston (3) can be controlled via a first switching valve (11) switched by a magnetic valve (10). A chamber (C2) behind the displacement piston (4) can be exhausted via a second switching valve (14) switched by the same magnetic valve (10), whereby the pressure control piston (3) is held in its initial position to release the full valve aperture cross-section from the pressure line (1) to the clutch line (7).

An automatic clutch control system (200) is provided featuring programs for establishing optimum clutch engagement starting position (CPO) under varying operating conditions. The programs include the steps of both slow and rapid clutch engagement and preferably the storage of the (CPO) determined as a fault signal whenever its fractional relationship to the previously stored optimum clutch engagement starting position (CPN) exceeds a predetermined fraction (C6) that is less than one.

The invention relates to a method for operating a transmission device (1) for a motor vehicle, wherein the transmission device (1) has an automatic clutch (2) and a manual transmission (3). Provision is made here, in at least one type of operation of the transmission device (1), for the clutch (2) to be closed before a driving gear is engaged at the manual transmission (3) if, when the clutch (2) is at least partially open, actuation of the manual transmission (3) is identified. The invention relates to a transmission device (1) for a motor vehicle.
摘要:
A method of adapting the characteristic curve of clutches in a partial dual-clutch transmission of a vehicle, for example a utility vehicle, having a first partial transmission in the form of a dual-clutch transmission (DKG) having a dual clutch (DK) that includes a first clutch (K1) and a second clutch (K2), which can be functionally connected to a drive engine (M), and a second partial transmission in the form of a main transmission (HG) which shifts with traction force interruption and which is arranged downstream from the dual-clutch transmission (DKG) in a drive-train. To achieve reliable and precise clutch control and a consistently high level of shifting comfort, the characteristic curve adaptation of the first and the second clutches (K1, K2) is carried out with the assistance of a pre-loading of the first and the second clutches (K1, K2), while the main transmission (HG) is in a neutral position.

The invention is related to a clutch control system which makes it possible to reduce the weight of the system as a whole while preventing a large driving force from acting on a transmission, by performing a predetermined vehicle start inhibition control.
摘要:
To provide a clutch control system with which the load exerted on transmission gears at the time of shifting from a neutral state to an in-gear condition can be reduced by disengaging a clutch in response to detection of the neutral state. The clutch control system includes a motor (21) in a liquid pressure modulator (20) for engagement/disengagement of a clutch (6), a clutch control unit (130) for controlling the operation of the motor (21), vehicle condition detection means (170) which detects at least that an engine is in working and which detects the running speed of the vehicle, and neutral detection means (190) for detecting the neutral state of a transmission (1). When the engine being in working and the vehicle speed being in excess of a predetermined value is detected, the neutral state is detected, and the clutch is in a partially or engaged state, transition to the clutch disengaged state is effected. The clutch is also disengaged when a jump-out situation is generated in the transmission (1).
