ABSTRACT:
In an automated multi-group transmission consisting of one front-mounted group, one main group and one range group and in which the front-mounted group transmission and the range group transmission comprise a first shifting position for a low-speed total transmission ratio, a second shifting position for a high-speed total transmission ratio and a third shifting position as neutral position for interrupting the torque transmission, in a gear-shifting method for gear change, the range group transmission and the front-mounted group transmission are simultaneously brought to their respective neutral shifting position, which makes it possible to shift a deceleration of the main transmission. With the start of the gear-shifting process in the neutral positions, there also begins the control of the engine rotational speed to the total ratio of the target gear.
