    摘要: A process for actuating a hydraulic storage device (5) of a transmission unit comprising a storage space (9) whose volume can be varied between a minimum and a maximum. The volume of the storage space can be changed by acting upon the storage space with pressurized hydraulic fluid from a pressure supply (19) of the transmission unit. To overcome a restoring tendency of the hydraulic storage device, the pressure is set to a threshold value. A holding device (12) holds the hydraulic storage device at least in the operating condition that corresponds to the maximum volume of the storage space against the restoring tendency. The storage space is acted upon by the pressure supply with a pressure corresponding to a threshold value (P_threshold) until the hydraulic storage device reaches the operating condition in which it can be held by the holding device.

    摘要: A process for operating a power train of a vehicle, during an activated internal combustion engine (2) start/stop function. The power train includes the engine (2), which is started with torque from a starter (3), an output (5), and a non-positive shifting element (6A), having a continuously variable transmission, and a starting device (6) arranged between the engine (2) and the output (5). A portion of the torque from the engine (2) and/or the starter (3), depending on a set shifting element (6A) transmission capacity, is directed by starting device (6) toward the output (5). When there is a demand for starting the engine (2), the shifting element (6A) transmission capacity is adjusted to an amount at which at least a portion of the torque, generated by the starter (3), exceeding the needed torque to start the engine (2) during the startup procedure, is directed to the output (5).

    摘要: A vehicle transmission having shifting elements (A-E) and a parking brake for locking a drive train output and a method for controlling the transmission. Activation of the parking brake depends on a driver's control action. Deactivating the parking brake, when the vehicle is on a slope greater or lesser than a preset value and depending on the slope, a combination of shifting elements (A, D) or (B, D) frictionally slip, such that the output rotates against the strain on a parking brake locking element, caused by the slope, to partially eliminate this strain. Next, one of shifting elements (C, A or B) engages locking the output. The parking brake is then released and finally, the engaged shifting element (C or A or B) is disengaged in a regulated manner, such that the output can be driven according to the driver's control action.

    摘要: A vehicular parallel hybrid drivetrain contains a combustion engine, electric motor and drive output and a method of operating the drivetrain. A respective shift element device (6, 7) with continuously variable transmission capacity is provided, between the combustion engine and the electric motor and between the electric motor and the drive. The shift element device (6), between the combustion engine and electric motor, comprises a speed-dependent hydraulic coupling element and a frictional shift element in a parallel power branch. The shift element device (6) has continuously adjustable transmission capacity and is bridged, via the hydraulic coupling element. The hydraulic coupling element actively couples with the electric motor, via a free-wheel overrunning connection (8). This coupling disengages when the speed of the coupling element side of the coupling element is lower than the speed of the electric motor in the area of the free-wheel overrunning connection.

    摘要: A method of operating a drive train having a hybrid drive including a combustion engine and electric motor, a clutch located between the engine and the motor, a transmission, a starting element and a brake pedal. For electric crawling from a state in which the clutch is disengaged, the brake pedal is activated and the combustion engine is turned off, initially the starting element is brought to or maintained at a filling pressure. Next, the rotational speed of the electric motor is adjusted to be higher, by a defined slippage rotational speed, than a transmission side rotational speed. When this slippage is reached, the starting element is further engaged to create a crawl torque at the output. The electric motor continues at rotational speed control so that the slippage is maintained.

    摘要: A hydraulic system in motor vehicles with at least one hydraulically actuated clutch, which entails minimized control complexity for supplying the clutch with hydraulic oil and which takes up less structural space. These characteristics are achieved essentially in that the pressure control of the hydraulically actuated clutch is effected directly and exclusively by an electrically driven and electronically controlled oil pump.
