Driveline angle analyzer
First Claim
1. A computer implemented method of determining a driveline inertia of a vehicle driveline resulting from an oscillatory speed effect in a vehicle driveline configuration, the driveline including a driveline component rotationally coupled to a propshaft at a non-zero working angle using a universal joint, the method comprising:
- entering measurements of the vehicle driveline configuration into a graphical user interface program, wherein the entered measurements of the driveline configuration includes measurements indicative of working angle between the propshaft and the driveline component;
determining an oscillatory speed effect of the vehicle driveline component based on the entered measurements;
determining a driveline inertia resulting from an oscillatory speed effect of the vehicle driveline by using, at least in part, the rotational speed of the driveline component, the working angle between the driveline component and the propshaft, the inertia of the driveline component, and the inertia of the propshaft; and
providing an output indicative of the driveline inertia in a tangible medium.

Abstract
A Driveline Angle Analyzer (DAA) for determining a torsional acceleration and inertias of a vehicle driveline by entering measurements of a vehicle driveline configuration into a graphical user interface program. The user selects the driveline configuration of interest from a plurality of driveline configurations. Then, the user enters information, such as driveline measurements relating to the selected driveline configuration. To aide in gathering the correct information, the user can print out a worksheet for the selected driveline configuration. After the user inputs the information for the selected driveline configuration, the user can select a corrective mode that allows the user to improve the selected driveline configuration. For example, the user can change the angle of a component with the surrounding components by changing their angles and/or length while enabling the components to stay connected to each other, thus maintaining the vehicle'"'"'s driveline geometry.
