Method for the performance of the gear disengagement in a servo-controlled manual gear change

摘要

A method for the performance of the gear disengagement in a servo-controlled manual gear change (5), according to which an oscillation is generated with respect to the angular speed ( omega 1(t)) of a primary shaft (7) of the gear change (5) by abruptly opening the relative clutch (4) and the disengagement of the gear (A) is performed around the maximum amplitude of an oscillation half-wave, when this oscillation has caused the angular speed ( omega 1(t)) of the primary shaft (7) to be relatively close to the angular speed ( omega 1B) that the primary shaft (7) has to assume to carry out the engagement of the subsequent gear (B).
