Abstract
A method to automatically control a drivetrain provided with a servo-assisted transmission; the method presents the steps of: measuring a rotation speed of the internal combustion engine; carrying out a downshift to a lower gear in an autonomous manner, when the rotation speed of the internal combustion engine reaches a lower threshold; carrying out an upshift to a higher gear in an autonomous manner, when the rotation speed of the internal combustion engine reaches an upper threshold; detecting a release of an accelerator pedal in a first instant; waiting, starting from the first instant, a time interval until a second instant, which is subsequent to the first instant; and increasing a value of the lower threshold starting from the second instant until a following pressing of the accelerator pedal, if in the second instant the rotation speed of the internal combustion engine still exceeds the lower threshold.
