摘要： A control valve arrangement having a clutch regulation valve (3), which pressurizes a device to actuate the clutch, and a valve that produces a controlled pilot pressure (P_VST3). An electronic control unit (ECU) controls a valve to supply a control valve with the pressure (P_VST3). The arrangement further having a hydraulic system which, if the ECU fails and the pressure (P_VST3) ceases, the last shift condition of the clutch actuation device, prior to the ECU failure, can be maintained in an emergency. The arrangement includes a valve, which delivers an activation pressure (P_A), depending on an engine-speed-dependent control pressure (P_D), to an actuation valve (2), which then delivers the pressure (P_A) to the valve (3) to prevent the emergency function initiation despite a lack of pressure (P_VST3) and existance of the pressure (P_D) sufficiently high to initiate the emergency function.

摘要： A valve assembly for controlling actuation of at least one starting clutch of an automatic transmission includes at least one clutch control valve through which a supply pressure is directed to a clutch actuation device, a pressure control valve controlled by a control device to supply at least one control valve of the valve assembly with a pilot pressure, a self-maintained hydraulic unit to maintain operation of an engaged starting clutch upon failure of the control device and loss of the pilot pressure. The valve assembly has a self-maintained valve and an activation valve. The self-maintained valve directs an activation pressure or control pressure, depending on the engine or transmission speed, to the activation valve. The actuation valve directs the activation to at least one clutch-regulating valve. The valve assembly also controls actuation or de-activation of the emergency operation function with a clutch actuation pressure.

摘要： A method for emergency actuation of an automated dual-clutch transmission of a vehicle with electrohydraulic control via a transmission control device. The method includes disengaging one clutch of the dual-clutch transmission, in order to realize emergency operation of the transmission and applying pressure on the other clutch after an error signal is transmitted indicating a malfunction of the transmission and/or the transmission control device. In order to keep the complexity of the hardware of the hydraulic system low, both clutches are disengaged, when an error signal occurs, and adjusted to a safe initial state, and an actuating pressure is only re-applied to one of the two clutches after the initial state is reached. In addition to the already existing elements of the hydraulic system, only one device or software is required which detects and selects the clutch that is more advantageous for continued driving operation.

摘要： The invention involves a control valve arrangement to activate at least one start-up clutch of a motor vehicle automatic transmission with at least one clutch control valve (3, 3′, 3″) across which a supply pressure (P_V1) can be led into a pressure chamber of an associated clutch activation device (4, 4′), with a pressure regulating valve (166), which is controlled by an electronic control device, and at least one control valve of the control valve arrangement is supplied with a pilot pressure (P_VST3), and with a self-maintaining hydraulic unit with whose help a hydraulic emergency operation can be maintained with a closed start-up clutch upon the failure of an electronic control device and thus the absence of a pilot pressure (P_VST3) in at least many operational situations. This control valve arrangement is characterized in that the self-maintaining hydraulic unit to achieve the emergency operation function has a self-maintaining valve (1) and an activation valve (2), in that the self-maintaining valve (1) is constructed such that it is suitable for forwarding an activation pressure (P_A) depending on a motor rotational speed or the transmission output rotational speed control pressure (P_D) to the activation valve (2), in that the activation valve (2) is able to forward the activation pressure (P_A) to at least one clutch-regulating valve (3, 3″), and in that the control valve arrangement is equipped with the means with which the activation or deactivation of the emergency operation function can be controlled by the clutch activation pressure (P_K, P_K′).
