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