  • Method and device for controlling a powertrain test stand
    Patent number: 9651452
    Abstract: Disclosed are a method and a control device for controlling a powertrain test stand comprising a driving machine and a driven machine. According to the invention, a torque supplied by the driving machine is controlled, a reference variable (Mx) for controlling the torque of the driving machine in order to dampen vibrations between the driving machine and the driven machine being modified depending on a current speed (nist) of the driving machine in relation to a predefined value (Mist), the reference variable (Mx) being determined from a model of a virtual tire.
    Type: Grant

  • Method for damping vibrations while testing a drivetrain having at least one shaft
    Patent number: 9632007
    Abstract: The invention relates to a method for damping vibrations while checking a drivetrain which has at least one shaft and to a device for carrying out the method. The shaft is connected to at least one drive or load machine for adjustment of a drive or load torque, a target value of the drive or load torque being specified for the machine. A shaft torque which is dependent on the relative rotation between two points on the shaft is measured, and the measured shaft torque as such is applied to the target value of the drive or load torque.
