  • Patent number: 10738911
    Abstract: A method for actuating a valve device as a function of a characteristic curve including actuating the valve device with a dither superimposed on a target value (i_EDS) with such a frequency that the operating condition of the valve device follows the actuation corresponding to the characteristic curve (v_kk). The method further includes determining, with the characteristic curve (v_kk), the output values (“1”, x) which correlate with the target values (i_EDS) at inflection points of a harmonic oscillation impressed upon the valve device with the dither, and determining further output values as a function of the output values (“1”, x). The amplitude of the dither is predefined such that, during an actuation of the valve device, one of the inflection points lies in a first or second characteristic curve range (v_kk1 or v_kk3, v_kk3 or v_kk5), and another inflection point lies in a third characteristic curve range (v_kk2 or v_kk4).

  • Patent number: 10738839
    Abstract: A clutch arrangement is formed with drive-side and, output-side clutch elements and a clutch piston for operative connection and disengagement between the drive-side and output-side clutch elements. Associated with at least two clutch elements is an elastically deformable clutch element working mechanism through which the corresponding clutch elements can be acted upon in direction away from one another by an axial force to assist disengagement of the drive-side and output-side clutch elements. The clutch element working mechanism provides a considerable change in the gradient of the axial force exerted on the clutch elements as a result of even a small change of shape of the clutch element working mechanism so that a sharply rising axial force of the clutch element working mechanism works against the clutch piston.

  • Patent number: 10724634
    Abstract: A parking lock device for a motor vehicle including a parking interlock gear and a parking pawl. The parking interlock gear has teeth and tooth gaps, wherein each of the teeth has a first and a second deflecting contour that are counter-revolving and radially increasing from a radial indentation toward a respective tooth flank. The parking pawl includes a ratchet tooth. The parking interlock gear is rotatable about an axis of rotation and the parking pawl is rotatable about or translational along a swivel axis parallel to the axis of rotation. The contours slidingly guide the ratchet tooth to catapult over the tooth gaps in a targeted rotational speed range of the parking interlock gear, the targeted rotational speed range being between a minimum limit speed and a maximum limit speed, such that contact is avoided between tooth flanks of the parking pawl and of the parking interlock gear.

  • Patent number: 10717426
    Abstract: A method for operating a drive train of a motor vehicle includes selecting between first and second operating strategies for controlling a starting component (3A, 3B) during a stopping process of the motor vehicle, and carrying out a downshift of the transmission (G) during the stopping process after implementing the first operating strategy or the second operating strategy. In the first operating strategy, the starting component (3A, 3B) is engaged or locked up and/or remains engaged or locked up at least until the motor vehicle comes to a standstill. In the second operating strategy, the starting component (3A, 3B) is disengaged or the lock-up of the starting component (3A, 36) is released before the motor vehicle come to the standstill. The downshift of the transmission (G) is triggered at a different rotational speed limit value upon implementation of the first operating strategy than upon implementation of the second operating strategy.
