A method for operating a hybrid drive in a vehicle with an internal combustion engine and at least one electric machine connected thereto which is in connection with at least one energy storage device including operating the internal combustion engine is operated in overload mode in at least one preferably exceptional operating situation of the hybrid drive in order to avoid power losses at low loading state of the energy storage device.

Method for operating an internal combustion engine

In a motor vehicle with a clutch that is operable in an automated mode, parts () of the clutch-actuator and/or the control device of the actuator system are integrated in a carrier element () that is installed in an intermediate area between the clutch bell housing () and the transmission housing ().

Motor vehicle

The magnitude of torque which can be transmitted by a bypass clutch between the housing and the turbine of a torque converter between a prime mover, such as an engine, and an automatic transmission in the power train of a motor vehicle is selectively regulatable by a computerized regulating unit. The regulation involves the transmission of torque by the clutch in dependency upon the magnitude of the torque being transmitted by the output element of the engine and ascertaining as well as adaptively applying to the clutch a variable force so that the clutch can transmit a predetermined torque. This entails automatic selection of a minimum slip between a torque receiving and a torque transmitting part of the power train. Compensation, particularly long-range compensation, is carried out for the existence of possible differences between the predetermined and actual torques being transmitted by the clutch.

Method of and apparatus for transmitting torque in vehicular power trains

The invention relates to a method for controlling and/or regulating a drive train in a vehicle with an engine and a gearbox, especially an automatic gearbox, whereby depending on a warning signal and a stopping request of the driver an engine stalling aid is launched. The invention also relates to a drive train for a vehicle with an engine and a gearbox, especially an automatic gearbox, especially for carrying out said method.

Drive train and method for controlling and/or regulating a drive train

A power transmission for a motor vehicle. The transmission includes a plurality of transmission ratio steps defined by pairs of gear carried on parallel shafts, and final output mechanisms for engaging desired transmission ratio steps. The final output mechanisms are operable for controlling the engagement of respective transmission ratio steps to minimize tractive force interruption by allowing rapid gear changes to be effected to reduce the times between shifts of gears. By sensing accelerator pedal position and vehicle speed a new transmission ratio step to be subsequently engaged can be pre-selected while an engaged gear remains engaged.

Transmission

A method for controlling an automated clutch of a motor vehicle, wherein the frictional engagement of the clutch is characterized by a physical friction value that changes dependent on an operating state of the clutch, has the steps of:

An automated clutch of a motor vehicle is controlled according to a method with the steps:

Method and apparatus for controlling a vehicle with a gear-shift transmission

A compliant link has a first member adapted to be connected to a linear actuator and a second member adapted to be connected to a component to be moved by the linear actuator, said members being interconnected by a connecting rod which is moveable relative to both the first and second members, springs acting between the first and second members and the connecting rod to oppose relative movement between the connecting rod and the first and second members when an axial load below a first predetermined value is applied to one of the members.

Compliant link

An adjustable pulley for use in a continuously variable transmission has two coaxial flanges at least one of which is a composite flange having an annular main section with a conical surface adjacent a reinforcing liner of wear resistant material. The liner is secured to the main section of the composite flange by a one-piece or composite disc-shaped insert one side of which has several portions affixed (such as bonded and/or riveted) to the adjacent side of the liner, and the other side of which has several portions affixed to the conical surface and/or another part of the main section. Those portions of the one side of the insert which are affixed to the liner are out of register with those portions of the other side of the insert which are affixed to the main section to thus enable the liner to move relative to the conical surface in one or more directions other than circumferentially of the main section.

Continuously variable transmission

A double clutch transmission in connection with an electric unit, as well as a method for operating the transmission.

Double-clutch transmission

A vehicle securing system to prevent a motor vehicle having an automated transmission with a clutch between the transmission and the engine from rolling away after turning off the ignition. The automated transmission includes a plurality of gears and a control device that receives signals representative of the vehicle's operating parameters and that processes them as well as engages the driver-selected transmission gear. The control device is operative after ignition shutoff for a predetermined time period, or is operative after ignition shutoff by operation of a brake pedal, and effects the engagement of a selected gear when the vehicle is moving at a speed that is lower than a predetermined threshold speed value.

Vehicle securing system

An actuating device for an operating element such as a clutch ( ) in the power train between the engine ( ) and the driven wheels ( ) of a motor vehicle consists of a parallel arrangement of at least two actuators ( ) that are controlled by an electronic control device ( ) 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.

Actuating device with two parallel mounted actuators

A pressure-medium actuated clutch that includes a plurality of clutch disks and a piston slidably positioned for movement toward and away from the disk to selectively engage and to disengage the clutch. A pressure chamber is provided adjacent to the piston and communicates with a source of pressurized fluid. A pilot-pressure-operated control valve is provided to control the pressure of the pressurized fluid, and a flow constriction is provided in a conduit extending from the control valve to the pressure chamber. A method for actuating the clutch is also disclosed.

Pressure-medium-actuated clutch

The present invention proposes a power train and the operation thereof, suitable for automated actuation of a transmission shiftable between a plurality of gears with a torque transmitting system being actuated automatically at least during a gear change, at least one actuating element operable by at least one drive unit and at least one actuatable shift element being disposed at the transmission side. The invention provides a power train in which a driving connection is disposed between at least one actuatable shift element associated with the transmission and an actuator having at least one drive unit, and at least one presettable elastic means is provided in the power transmitting path of the driving connection between the drive unit and the at least one shift element. Further, at least one additional presettable elastic element can be disposed in the power transmitting path between the at least one actuating element and the at least one shift element on the transmission side.
