    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: The invention describes a method for operating a transmission's valve system of a vehicle's drive train through a valve unit and said valve unit's electro-magnetic activator configuration. In a transmission's hydraulic system and being part of the vehicle's drive train, its hydraulic pressure value (p_EDS) can be employed and adjusted through a valve unit's configuration by applying to the electro-magnetic activator system a pulse-width-modulated current signal (i_EDS). The pulse-width modulated current signal (i_EDS) and its signal's amplitude (A) and/or its pulse duration (pw1) will periodically change during the applied Dither-Modulation, by maintaining at the same time the required pressure value (p_EDS), whereby a horizontally moving anchor, which is attached the valve system's valve shaft, receives hereby an imposed vibrating oscillation. As shown in this invention, the Dither-Modulation will be activated or deactivated accordingly during pre-defined operating conditions of the vehicle's drive train.

    摘要: A process of monitoring a drive direction of 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 includes 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.

    摘要: A hydraulic system for actuating a transmission shifting element that comprises control and shifting valves. A first surface of a valve slide of the control valve is a differential surface between two functional surfaces of the slide that axially bound an area of the slide having a smaller diameter, by which the actuation pressure is adjusted. When the shifting valve is in a second switch position, a total force component acts upon the slide of the control valve which moves the slide such that the actuation pressure is equal to a system pressure. The total force component corresponds at least to the sum of a first force component equivalent to a pressure signal applied to a second surface of the slide of the control valve and a second force component equivalent to an actuation pressure applied to the first surface of the slide of the control valve.
