Abstract
The present invention relates to a method for correcting a drag torque curve of at least one rotatable machine element of which the drag torque is dependent on the rotational speed of the machine element, wherein the drag torque curve has a plurality of rotational speed ranges which are different from one another, in which the drag torque curve in each rotational speed range is corrected between a measured rotational speed of the machine element and a calculated rotational speed of the machine element on the basis of a rotational speed deviation in the respective rotational speed range.
Claims10
A method for correcting a drag torque curve of at least one rotatable machine element, in particular of a torque transmission section of a vehicle drive train, which can preferably be coupled effectively in terms of drive to a drive by means of a first clutch and to an output of the vehicle by means of a second clutch, and the drag torque thereof, and therefore the drag torque curve, are dependent on the rotational speed of the machine element, wherein the drag torque curve has a plurality of rotational speed ranges which are different from one another, and wherein the drag torque curve in each rotational speed range is corrected between a measured rotational speed of the machine element and a calculated rotational speed of the machine element on the basis of a rotational speed deviation in the respective rotational speed range.
