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.
Claims11
A method for correcting a drag torque curve of at least one rotatable machine element of a torque transmission section of a vehicle drive train, the vehicle drive train coupled to a drive with a first clutch and coupled to an output of the vehicle with a second clutch, and a drag torque thereof, and therefore the drag torque curve, are dependent on a 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 of the rotational speed ranges 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 ranges.
A method for correcting a drag torque curve, comprising:
- providing at least one rotatable machine element of a torque transmission section of a vehicle drive train, the vehicle drive train coupled to a drive with a first clutch and the vehicle drive train coupled to an output of the vehicle with a second clutch;
- establishing a predefined drag torque curve for the at least one rotatable machine element;
- dividing the drag torque curve into a plurality of rotational speed ranges;
- and
- establishing a corrected drag torque curve based on a determined rotational speed deviation in each of the rotational speed ranges which is a difference between a measured rotational speed and a calculated rotational speed at each of the rotational speed ranges.
