摘要： Operating a drive train of a vehicle having a clutch assembly, wherein the clutch assembly is actuatable via an actuating device for the switchable transmission of a torque, wherein a first state of the actuating device, and thus a second state of the clutch assembly, is settable via a position of a drive unit of the actuating device, comprises: a) determining that a first torque request to the clutch assembly is constant; and b) determining that a first position of the drive unit is constant within the interval; and then c) controlling the drive unit with a dither function, wherein a position of the drive unit is continuously varied about the first position; and d) ending the dither function when the conditions stated in steps a) and b) are no longer met.

摘要： A parking lock arrangement for a drive train of a motor vehicle includes a controllable locking mechanism and an unlocking mechanism. The controllable locking mechanism includes a spindle drive with a spindle shaft rotationally drivable about a spindle axis, an actuator for rotating the spindle shaft and a positioning element movable by rotating the spindle shaft for actuating a blocking element. The blocking element acts at least indirectly on a drive element in a blocking or releasing manner. The unlocking mechanism includes an unlocking element and a manually operable control element. The unlocking element is movable via the control element from a normal position, in which the unlocking element is spaced apart from the spindle shaft, into an engagement position, in which the unlocking element is coupled in torque-transmitting manner to the spindle shaft for forced releasing of the locking mechanism.

摘要： A vehicle drive train, has a clutch unit actuatable by an actuating unit, and a sensor for determining the coupling status. The actuating unit includes an electromagnetic actuator having a piston movable from a starting to an end position. At least the piston and the clutch are acted on by a transmission fluid. Operating the drive train can include: a) actuating the actuator and moving the piston from the starting position; b) ascertaining a measured sensor value; c) ascertaining a temperature of the transmission fluid by measuring an electrical resistance of the actuator and/or measuring a first time interval between actuation of the actuator according to step a) and the detection by the sensor of an intermediate position that is reached by the piston; d) determining an actual position of the piston based on the measured sensor value and the temperature; and e) moving the piston, starting from the determined actual position, into the end position.

摘要： A hydraulic actuator can be provided for actuating a functional part by a movement of a force transmission element, with a working piston which can be acted upon by a hydraulic pressure of a pressure supply and is movable thereover between a first extreme position and a second extreme position in a piston/cylinder unit, wherein two chambers separated from one another by the working piston are present and a first chamber is formed as a first working chamber with a pressure inlet and a hydraulic pressure applied to the first pressure inlet urges the working piston in the direction of the first extreme position in order to enlarge the first working chamber.
At least one retaining means is provided which is capable of automatically locking the working piston in one of the extreme positions when this extreme position is reached, even without any hydraulic pressure being applied.
