1. Introduction
The study of automotive transmissions has been faced up deeply during last years, with the aim of obtaining better vehi-
cle performances, in particular during the gear shift phase and, eventually, to reduce the fuel consumption [3,6,2]. Among
this general background, depending on the transmission type, different problems still require to be solved: torque gap for
manual transmission (MT) [4,7]; engine rotating inertia acceleration for continuously variable transmission (CVT) [9];
efficiency for automatic transmission (AT) [5].
To reduce such drawbacks, many car makers recently started to develop new systems. Torque gap fillers (TGF) devices can
be used on automated manual transmissions (AMT) aiming at eliminat
