Zusammenfassung:	The disclosure describes, in one aspect, a method for changing a direction of a machine that is moving in a first direction. The method includes the step of receiving a signal indicative of an intention to change the direction of the machine to a second direction. The method also includes the step of determining whether a signal indicative of a speed of the machine is greater than a threshold based at least in part on an electric motor parameter. Finally, the method includes the step of applying a braking torque to at least one travel mechanism of the machine in response to a signal indicative of an accelerator pedal position until the speed reaches the threshold. L'invention porte, dans un aspect, sur un procédé pour changer la direction de la marche d'une machine qui se déplace dans une première direction. Le procédé comprend l'étape de réception d'un signal indicatif d'une intention de changer la direction de la marche de la machine en une deuxième direction. Le procédé comprend aussi l'étape de détermination du point de savoir si un signal indicatif d'une vitesse de la machine est supérieur à un seuil sur la base au moins en partie d'un paramètre électrique du moteur. Finalement, le procédé comprend l'étape d'application d'un couple de freinage à au moins un mécanisme d'entraînement de la machine en réponse à un signal indicatif de la position de la pédale d'accélérateur jusqu'à ce que la vitesse atteigne le seuil.
