摘要： A hydraulic control apparatus for an automatic dual clutch transmission, comprising a first clutch with a first partial transmission and a second clutch with a second partial transmission, as well as a shifting system for engaging/disengaging gears of the two partial transmissions, a control unit having a first pressure regulator and a second pressure regulator actuating the first and second clutches and actuating the shifting system, and a switching apparatus. The shifting apparatus comprises a first changeover valve and a second changeover valve. Both changeover valves can be shifted from a first to a second position for allowing a safe emergency running mode of a motor vehicle in case of any failure of the first or second pressure regulator.

摘要： The invention relates to a switching-valve arrangement for a shifting system of an automatic transmission having a first actuator for engaging and releasing gears, at least a second actuator for engaging and releasing gears, a first activatable switching valve, a second activatable switching valve, a first signal element, and a second signal element. By means of the signal elements and switching valves the first and second actuators can be pressurized. In case of failure of one of the signal elements one of the actuators can always be pressurized and even in case of erroneous operation of the first and second signal elements only one of the actuators can be pressurized at the same time.

摘要： The invention relates to a hydraulic control device for an automatic dual-clutch transmission which has a first clutch and a second clutch, having a control valve unit which predefines at least one hydraulic parameter such as pressure and/or one volume flow. Regulating this parameter engages or disengage the clutches. An additional separating valve can is provided assuming a normal position when the second control signal is applied, so that at least one of the clutches can be operated by means of the control valve unit. The purpose is to provide enhanced operational safety against misoperation while at the same time secure availability of the clutches.
