An illustrative example embodiment of a system for providing an indication to a driver includes a clutch that is at least partially automatically controllable and clutch control means configured to control the clutch in a manner that results in a haptic indication to a driver based on at least one predefined condition. In an example embodiment, the clutch control includes automatically adjusting an amount of clutch engagement to provide the haptic indication.

A transmission changes gears in a MT system, an AT system, and an AMT system wherein unintended transition between an AT mode and a MT mode or between an AMT mode and a MT mode is prevented. A selector in a controller performs a mode selection control such that, when performing transition between the AT mode and the MT mode or between the AMT mode and the MT mode, the driver at least has to operate a mode switching switch while operating a clutch lever in an operation amount not smaller than a predetermined threshold.

A method for controlling a manual transmission includes using a controller to determine a desired torque transmitted through an input clutch and a desired clutch slip for the desired gear after a shift lever is moved to a desired gear position and while a clutch pedal is being released for engaging the clutch; measuring torque in the vehicle drive assembly; using measured torque to determine actual clutch torque transmitted through the clutch; and reducing torque error using the controller to adjust a clutch actuator such that a difference between the desired torque and the actual torque is reduced. Slip error may also be reduced by adjusting the clutch actuator to reduce the difference between the desired slip and measured slip.

A shifting arrangement for a transmission includes a shifting sleeve, a friction clutch and an actuating element. The shifting sleeve is rotatable between a first position, wherein a first free gear is rotatable relative to a shaft, and a second position, wherein the first free gear is rotatably fixed to the shaft. The friction clutch assembly is movable between a first position, wherein two parts are rotatable relative to one another, and a second position, wherein the two parts are frictionally coupled. The actuating element is movable between a neutral, intermediate and positions. In the neutral position, the shifting sleeve and the friction clutch assembly are in their first positions. In the intermediate position, the shifting sleeve is in its second position and the friction clutch assembly in its first position. In the shifting position, the shifting sleeve and the friction clutch assembly are in their second positions.

A vehicle driving device includes: a clutch that is provided between a driving shaft of an engine and an input shaft of a manual transmission and that connects the driving shaft and the input shaft to each other or disconnects the driving shaft and the input shaft from each other; a detection unit that detects an obstacle that is an obstacle to traveling of a host vehicle; a collision possibility determination unit that determines a possibility of collision between the obstacle and the host vehicle based on obstacle detection information detected by the detection unit; and a collision avoidance unit that, when the collision possibility determination unit determines that there is a possibility of collision with the obstacle, performs a fuel cut of the engine even if a rotation speed of the engine is less than an idling rotation speed.

A method of controlling an automated friction clutch arranged as a starting and shifting clutch in a vehicle between an engine driveshaft and an input shaft of a transmission. The clutch can be engaged passively by a contact pressure spring and disengaged and engaged by a pneumatic control cylinder. The air inlet and outlet valves are opened in a sustained-pulse operating mode, over a duration ΔtV calculated as the quotient of air mass difference ΔmK between the nominal mass mK—soll present in the pressure chamber of the control cylinder when the control piston is in its nominal position xK—soll and the actual air mass mK—ist present when the control piston is in its actual position xK—ist (ΔmK=mK—soll−mK—ist) and air mass flow mv passing through the control valve concerned, which depends on the existing pressure situation and the flow characteristics of the open inlet or air outlet valve (ΔtV=ΔmK/mv).

A shift control device includes a clutch for performing a connection/disconnection of power transmitted to a drive wheel from an engine based on an operation input to a shift operator, an actuator for performing a drive control of the clutch, and a controller for controlling the driving of the actuator. The controller includes an operation quantity detector for detecting an operation quantity of a shift operator, a shift starter performing a control toward the disengagement of the clutch by driving the actuator at a stage in which an operation quantity detected by the operation quantity detector exceeds a first threshold value, and a shift starter for performing a disengagement control of the clutch by driving the actuator at a stage wherein an operation quantity detected by the operation quantity detector exceeds a second threshold value which is larger than the first threshold value.
摘要:
An actuating device for an operating element such as a clutch (4) in the power train between the engine (2) and the driven wheels (12) of a motor vehicle consists of a parallel arrangement of at least two actuators (25a, 25b) that are controlled by an electronic control device (31) so that they can work simultaneously or one after the other, or with a partial time overlap where one starts to work after an initial current surge to the other has subsided.

The invention concerns an automatic clutch in the drive train of a motor vehicle having a transmission with manual or voluntary selection of the different gears. After a gear-change, the engagement of the clutch is controlled as a function of the shift speed during the gear-change, such that, at high shift speeds, only a shortened clutch slip phase can occur.
