English to French Tech/Engineering Mechanics / Mech Engineering vehicle

Specifically, start-off pre-shifting is performed by releasing the engagement of the selective gear enmeshment mechanism for the currently selected gear train (placing the gear train into an unselected state) while the vehicle is decelerating, and engaging the selective gear enmeshment mechanism for the starting gear train (placing the starting gear train into a selected state), thereby effecting start-off pre-shifting.

Specifically, while the vehicle is decelerating, the automatic clutch CA or CB for the currently selected gear train is disengaged (thereby putting both automatic clutches CA and CB into disengaged states), the gear enmeshment of the selective gear enmeshment mechanism for the currently selected gear train is disengaged (putting the gear train into an unselected state), and the selective gear enmeshment mechanism 1 1 of the starting gear train (the first gear gear train if the vehicle is traveling forward) is enmeshed by the shifting of the coupling sleeve 12 is the corresponding direction (left in Figure 2) to put the starting gear train (first gear gear train) into a selected state.
