  • Patent number: 11920646
    Abstract: A method for operating a friction-locking shift element of a transmission of a motor vehicle includes actuating the friction-locking shift element for engagement according to a pressure versus torque characteristic curve. The pressure versus torque characteristic curve has a first characteristic point (a touch point) and a second characteristic point (a contact point), defines a first characteristic curve range between the touch point and the contact point having a first functional dependence, and defines a second characteristic curve range at or after the contact point having a second functional dependence. Once the touch point is reached, the friction-locking shift element begins to transmit torque mainly due to drag torques. Whereas, once the contact point is reached, the friction-locking shift element begins to transmit torque mainly due to friction between shift-element halves of the friction-locking shift element.

  • Publication number: 20240068563
    Abstract: A method for operating a drive train (1) of a vehicle includes, in order to check the plausibility of an adapted charge pressure value, changing an actuating pressure of a starting component (7) corresponding to an adapted charge pressure value by an offset and ascertaining a resultant change in a torque of an electric machine (3). When the change in the torque of the electric machine (3) and the offset of the actuating pressure correspond to each other within defined limits, a plausible adapted charge pressure value is inferred. When the change in the torque of the electric machine (3) and the offset of the actuating pressure do not correspond to each other within the defined limits, an implausible adapted charge pressure value is inferred.

  • Patent number: 9327471
    Abstract: A flat composite component, in particular a vehicle body part, comprising a material composite having an outer layer, a barrier layer adjoining the outer layer and a carrier structure on which the barrier layer is arranged and which comprises a core which has a first cover layer on the side facing the barrier layer and a second cover layer on the side facing away from the barrier layer. According to the invention, the barrier layer and the carrier structure have thermal expansion coefficients which are selected such that a deformation of the material composite in the case of a temperature change at least largely stops in a range between ?50° C. and +80° C.

  • Publication number: 20080211266
    Abstract: Uncontrolled take-up of a shade and often unexpected noise development are perceived as disturbing by the operator. Therefore, it is provided that a shade arrangement with a length of shade material (10) and a take-up roll (12) to which the length of shade material is attached and which is pretensioned by spring force in the take-up direction of the length of shade, has a pressure volume (46) coupled to the free end (16) of the length of shade material (10) such that, when the length of shade material is unrolled from the take-up shaft (12), a pressure is built up in the pressure volume which, when the length of shade material is released from a position in which it is at least partially unrolled from the take-up roll, the take-up motion of the length of shade is braked.
