    摘要: A process is described for application of pressure on setting mechanisms of transmission elements, e.g., band brakes or disk clutches, of an automatic transmission, particularly of the transmission system of a vehicle. In the process the control pressure applied to the setting mechanism is varied in dependence on the operating conditions. In order to eliminate transition errors and improve adaptation of the meshing behavior of the switching element, the slide of the switching element is regulated at a value adapted to the operating condition involved of the transmission and/or the vehicle. Apparatus for the implementation of the process is also described, as well as a hydraulic control system for supplying the operational chamber of a setting mechanism at a transmission element, which operational chamber has a continual leakage. In this regard, a valve device, by which the operational chamber can be rapidly filed by activation of the setting mechanism, is installed parallel to a rapid-response control valve, with which the pressure force of the transmission element parts can be influenced in a targeted manner. In this manner, it is possible for driver to feel a spontaneous reaction of the vehicle when activating the clutch or an autotmatic lever for switching between forward and reverse operation, without thereby detrimentally affecting the sensitivity and reaction time of the control valve.

    摘要: A method of determining and reducing vibrations caused by a clutch (3) in a drivetrain (1) of a motor vehicle, in which the disturbing vibrations are detected by a control and regulating unit aided by suitable sensors and, if predetermined limit values are exceeded, at least one device is actuated by the control and regulating unit in such manner that the disturbing vibrations are completely eliminated or at least reduced in amplitude. At least one torque sensor (8, 9, 10) is used to detect the occurrence of vibrations in the drivetrain (1) and the torque sensor (8, 9, 10) is used to determine vibration amplitude.

    摘要: Impeller speed, which is difficult to measure when a torque converter includes an impeller clutch, is estimated based on a known relationship among impeller speed, turbine speed, and turbine torque. Turbine torque may be directly measured by a turbine torque sensor or estimated based on other measurements such as output shaft torque or vehicle acceleration. The relationship is stored in a controller in terms of the coefficients of a second order polynomial relating turbine torque to impeller speed and turbine speed. A slip speed is calculated based on a measured input shaft speed and the estimated impeller speed. Closed loop control is used to adjust the impeller clutch torque capacity to maintain a target slip.
