摘要： A method for adapting a biting point pressure of a hydraulically actuated hybrid disengaging clutch arranged in a hybrid drive train of a motor vehicle between an internal combustion engine and an electric machine includes step by step implementation during driving of the motor vehicle via a plurality of selected engagement operations of the hybrid disengaging clutch with a manipulation of a rapid filling routine. Proceeding from an initially stored biting point pressure, a setting pressure, which is reduced relative to a subsequent rapid filling routine, is incrementally increased step by step. An actual value, which is set in each case for a test parameter, is detected until the actual value corresponds to a setpoint value. A change in the transmission of torque of the hybrid disengaging clutch is derivable via the actual value.

摘要： The present invention teaches an apparatus for consistent and accurate on-site readings of fluorescence signals of coronavirus test result, with which a user directly reads a fluorescent light qualitatively instead of using electronic sensors. The fluorescent light is excited from a fluorescent source in a site of interest in a target assay. The device comprises a light source for generating an excitation light for exciting the fluorescent source of the target assay to generate a fluorescent light, a component for accurately transmitting the excitation light and the fluorescent light with less noise or reflection, a component for consistent detecting of the fluorescent source by bare eyes with minimal health risks, and a user control system that requires minimal training.

摘要： This clutch control device includes an engine (13), a transmission (21), a clutch device (26) configured to connect and disconnect motive power transmission between the engine (13) and the transmission (21), a clutch actuator (50) configured to drive the clutch device (26) and change a clutch capacity, and a control unit (60) configured to calculate a target value (Pt) of a control parameter (Ps) for the clutch capacity. When the target value (Pt) of the control parameter (Ps) immediately after system startup is defined as a first control target value (P1) and the target value (Pt) of the control parameter (Ps) during a clutch stroke at the time of the system startup is defined as a second control target value (P2), the control unit (60) is configured to set the first control target value (P1) to a value greater than the second control target value (P2).

摘要： A method for controlling an automated starter clutch (4) in a drive train of a motor vehicle (1), which drive train has a transmission (3). In at least one first mode, the starter clutch (4) is operated automatically and is transitioned in an event-controlled manner into a second mode, in which the starter clutch (4) can be operated in such a way that upon actuation of the starter clutch (4), at least one jolt-like movement of the motor vehicle (1) is caused. In the second mode, the actuation of the starter clutch (4) is initiated and controlled depending upon operation of an accelerator pedal (13).

摘要： A drive train arrangement for a motor vehicle includes at least one drive device, a start-up element arrangement, a gear drive arrangement, at least one driveshaft configured to drive drive wheels, an electronic operator control member configured to be operated, a torque control member, and a controller. The controller is configured to store torque regions for a change in load and to transmit a torque default value to the torque control member depending on an actuation of the electronic operator control member. The stored torque regions are zero transition regions with a zero transition starting point and a zero transition end point for covering all zero-load clearance regions. The controller is configured to adapt at least one respective zero transition region of at least one respective stored torque region.

摘要： Methods and systems for operating a clutch of an axle are provided. In one example, the clutch may be characterized in static or dynamic conditions. The clutch characterization may be a basis for subsequently operating the clutch during gearbox shifting. In particular, an amount of torque that is transferred via the clutch may be controlled or adjusted according to the clutch characterization.

摘要： The disclosure relates to a method for controlling an actuator or an actuator device, at least comprising a clutch and an actuator, which actuator has: an electric drive motor and a control device; a ramp mechanism, which comprises a rotatable first disk, which has first ramps, a second disk, which can be moved only in an axial direction and which has second ramps, and balls, which are arranged between the disks in the first ramps and second ramps; and at least one spring for moving the second disk in the axial direction. The dynamics of the electric drive motor are reduced by the control device at least in dependence on at least the determined preloading force or the first play in such a way that, during braking, the pin contacts only one side surface or that, in the event of a reversal of the rotational motion, the pin bridges the first play at a reduced first rotational speed of the drive motor and comes into contact with the other side surface and only then does an increase to a second rotational speed occur.

摘要： A driver assistance device for a motor vehicle with a drive assembly, which can be connected to a drivetrain via a clutch that can be activated by an actuator. The clutch being a component of an electronically controlled clutch system, in which a clutch pedal sensor detects an actuation of a clutch pedal on the driver's side and in which an analysis unit determines, in a first control mode on the basis of the detected clutch pedal actuation, a clutch torque and actuates the clutch with a corresponding clutch signal. For an adjustment of the clutch response on the driver's side, the analysis unit is associated with an input unit, for the actuation of which, on the driver's side, it is possible to shift between the first control mode and at least one second control mode.
