This paper has described a judder analysis conducted on an electronically controlled limited slip differential (A-LSD) system. Problems involving self-excited vibration of the drivetrain often must be solved by improving the my-v charakteristic (coefficent of friction - relative speed) of the friction materials that are the source of excitation, because the positive damping elements of the system are limited. The results of the judder analysis conducted in this work, however, identified several effective measures for dealing with this problem. These included the adoption of a torsional damper and determination of suitable specifications for it, as well as identification of an appropriate development target for the my-v characteristic of the multiplate clutch used in the A-LSD system. These measures contributed greatly to the successful development of the system. In future work, the authors plan to use these tools to solve other self-excited vibration problems.
