EINLEGEVERFAHREN UND -SYSTEM FÜR EIN NEUES GESCHWINDIGKEITSVERHÄLTNIS, AUFZEICHNUNGSMEDIUM FÜR DIESES VERFAHREN

摘要

This engagement method of a new speed ratio n_f includes: a) an action step (127) of an electric machine to make the angular speed ?₁ of an initial input transmission shaft converge to the angular speed ?₂ of a second shaft multiplied by the stepping-down of the gearbox dn_f of the new ratio n_f, and b) an action step (131) of a mechanical synchroniser in order to make the angular speed ?₁ converge to the angular speed ?₂ multiplied by the stepping-down of the gearbox dn_f of the new ratio n_f. Steps a) and b) are at least partially executed simultaneously. After step b) has been completed, the method involves an operation (134) involving regulation of the torque quantity transmitted by the mechanical synchroniser of the second shaft to the initial shaft or vice versa, via a maximum energy threshold that can be dissipated by the mechanical synchroniser.
