  • Patent number: 10859131
    Abstract: Controlling a multiplate clutch situated between an input shaft and an output shaft for the switchable transmission of torques, wherein in the event of a torque request and a subsequent engagement of the multiplate clutch, includes: a) determining a setpoint engagement force, acting in an axial direction, of the multiplate clutch for transmitting a setpoint torque to the output shaft; b) determining and setting a limiting engagement force that is less than the setpoint engagement force, and c) setting the setpoint engagement force in a time-delayed manner; wherein a transmission of an actual torque is achieved by limiting the setpoint engagement force to the limiting engagement force, so that a maximum actual torque that is transmitted upon engagement of the multiplate clutch exceeds a setpoint torque to be transmitted by at most 5%.

  • Patent number: 10233982
    Abstract: A clutch cylinder in a hydraulic pressure system can be charged with a controlled rotational speed of a pump to deliver hydraulic fluid into the clutch cylinder until a biting point of the clutch is reached and exceeded and a motor current of the pump has attained a predetermined minimum value. On the basis of a profile of the controlled rotational speed, a first volume of the hydraulic fluid delivered into the clutch cylinder by the pump up is determined until the minimum value is attained. The value of the first volume can be reduced by a predetermined amount to a second volume, which can be used for clutch processes during vehicle operation, wherein the second volume is delivered into the clutch cylinder, with a high rotational speed of the pump, such that the clutch is filled such that the biting point of the clutch is not quite reached.
