The invention relates to a method to control a road vehicle (1) provided with a servo-assisted transmission (7) during a slowing down phase. The control method comprises, when the servo-assisted transmission (7) is in an automatic operating mode, the steps of: calculating, assuming that a pressing of the brake pedal (23) remains constant, an opening time interval needed to allow the road vehicle (1) to reach an opening speed at which a clutch (16) of the servo-assisted transmission (7) is definitively opened; calculating a number of downshifts that can be carried out in the opening time interval based on a time needed to carry out a downshift; scheduling the downshifts to be carried out in order to get from the current gear engaged in the servo-assisted transmission (7) to an opening gearwith which the clutch (16) of the servo-assisted transmission (7) is definitively opened, so as to carry out no more than the number of downshifts that can be carried out in the opening time interval;and carrying out the scheduled downshifts.

    本发明涉及一种用于在减速阶段期间控制具有伺服辅助变速箱(7)的道路车辆(1)的方法,当所述伺服辅助变速箱(7)处于自动运行模式时,所述控制方法包括以下步骤:假设制动器踏板(23)的压下保持恒定,计算使道路车辆(1)达到最终松开伺服辅助变速箱(7)的离合器(16)的松开速度所需的松开时间间隔;基于进行降档所需的时间计算在松开时间间隔内能够进行的降档次数;计划为了从在伺服辅助变速箱(7)中挂的当前档到通过其最终松开伺服辅助变速箱(7)的离合器(16)的松开档要进行的降档,从而进行不超过在松开时间间隔内能够进行的降档次数;以及进行计划的降档。
