  • Patent number: 8315761
    Abstract: A method for the control of an assembly by a control unit, in particular in a motor vehicle, wherein the assembly includes at least one component, at least one actuator associated with the component, and an additional control unit having a first non-volatile memory section that is connected to the control unit. The control unit includes a second non-volatile memory section. Classification information associated with the assembly and stored in the first non-volatile memory section is read out and transmitted to the control unit. The transmitted classification information is stored in the second non-volatile memory section. Subsequently, the classification information stored in the second, non-volatile memory section is read out and transmitted to the additional control unit. The disclosure furthermore relates to an assembly group that comprises the assembly and the control unit, with the control unit and the additional control unit of the assembly being connected to one another by a data transmission path.

  • Patent number: 8229638
    Abstract: A method is described for classifying a clutch unit for a drivetrain of a motor vehicle, wherein the clutch unit has at least one friction clutch for the controllable transmission of a torque from an input element to an output element and has an actuator for actuating the friction clutch. Here, the clutch unit is controlled on the basis of a predefined characteristic curve which describes a predefined dependency of the clutch torque to be transmitted on an actuator control variable.

  • Publication number: 20110166760
    Abstract: A clutch unit comprises a wet friction clutch for controllable transmission of a torque from an input element to an output element, oil for cooling the friction clutch, and an actuator for actuating the friction clutch. In order to control the clutch unit, a temperature is ascertained in the friction clutch. A characteristic curve of the friction clutch that describes the dependence of a clutch torque on an actuator control variable is adapted as a function of the ascertained temperature. The clutch unit is controlled in accordance with the characteristic curve by means of the actuator.

  • Patent number: 7973437
    Abstract: The invention relates to a transmission for a motor vehicle with a transmission housing, with an electrical actuator for the actuation of the transmission and with an electrical control device for the control of the actuator. The transmission has a heat sink device 24 thermoconductively connected to the device and a heat insulating layer between a housing of the actuator and the heat sink device for the thermal insulation of the actuator housing and of the heat sink device, with the actuator housing being thermoconductively connected to the transmission housing or being part of the transmission housing. The invention furthermore relates to a corresponding actuator unit for a transmission.

  • Patent number: 7974758
    Abstract: A method and apparatus for setting the torque transmitted by a friction clutch via an actuator chain having an electric motor, a reduction gear and a mechanism for converting the rotary movement of the electric motor. In the method, a desired angle of rotation of the electric motor or a link of the actuator chain is determined from the torque to be transmitted by the friction clutch and is set in a setting procedure based on a given torque/angle dependence. To compensate for wear inside the friction clutch, a calibration process takes place in which a first correction angle is determined for the torque/angle dependence. Variations in a torque/power consumption dependence caused by wear within the actuator chain are also taken into account. Specifically, the number of setting procedures of the electric motor within a predetermined time interval is determined and is used to correct the torque/power consumption dependence.

  • Publication number: 20080277224
    Abstract: A method and apparatus for the setting of the torque transmitted by a friction clutch by means of an actuator chain having an electric motor which effects a displacement of a pressure plate of the friction clutch via a reduction gear and a mechanism for the conversion of the rotary movement of the electric motor. In the method, on the basis of a given torque/angle dependence, a desired angle of rotation of the electric motor or of a link of the actuator chain is determined from the torque to be transmitted by the friction clutch and is set in a setting process by means of a regulator acting on the electric 2.
