    摘要: A mechanism for actuating a transmission having shifting elements. A self-holding valve device is movable into a first position, by a pilot pressure, against a force directed to a second position and held by a pressure holding signal in the first position. Transmission of a pressure signal, to a switching valve, is blocked by the self-holding valve device in the first position but, in the second position, is applied to the switching valve. When the driver sets the switching valve to a first shift position, the pressure signal can be applied to valve devices of at least two of the shifting elements that produce an actuating pressure and, in a second shift position of the switching valve, the onward transmission of the pressure signal, to the valve devices of the shifting elements that produce an actuating pressure, is blocked in the area of the switching valve.

    摘要: A method for operating a multi-step automatic transmission arranged in a drive train of a vehicle with a combustion engine. When downshifting from the third gear ratio to a second gear ratio, higher inertia must be shifted than when shifting from the third gear ratio to the first gear ratio. Upon a demand for a coasting downshift from the third gear ratio to the second gear ratio or to the first gear ratio with no performance demand on the combustion engine, the coasting downshift to the second gear ratio is not executed and the first gear ratio is engaged when the requirements for downshifting to the first gear ratio are met.

    摘要: A process for monitoring a direction of drive from an automatic or automated vehicle transmission at near-zero vehicle speed via an engaged gear. A desired direction of drive of the transmission is determined from an engaged gear at the time the vehicle begins motion. An actual direction of drive is determined from the transmission and if different from the desired direction of drive, an error signal is produced. The process including determining the actual drive either from a sensed rotational direction of a transmission input shaft and a sensed rotational direction of a transmission output shaft or a sensed valve setting, a sensed pressure in an transmission electro-hydraulic control system or on a transmission shifting element or from a sensed direction of rotation of a transmission gearset element or from axial movement or force of a transmission constructional element.
