The invention relates to a method to control a road vehicle (1) for the execution of a multiple downshift in a drivetrain provided with a servo-assisted transmission (7) the control method comprises the steps of: detecting a condition of slowing down of the road vehicle (1) and, simultaneously, detecting a driver's request for a multiple downshift; carrying out, in succession, a plurality of downshifts while the road vehicle (1) is slowing down and in an autonomous manner regardless of further interventions of the driver; determining a duration of a shift time interval ([delta]t); and carryingout each downshift following a first downshift when the shift time interval ([delta]t) has exactly elapsed since the previous downshift.
本发明涉及一种用于在具有伺服辅助变速箱(7)的动力传动系统中执行多级降档来控制道路车辆(1)的方法,所述控制方法包括以下步骤:检测道路车辆(1)减速的情况,同时检测驾驶员的多级降档请求;在道路车辆(1)正在减速的同时连续且以与驾驶员的进一步干预无关的自主方式进行多级降档;确定换档时间间隔(Δt)的持续时间;以及在第一级降档之后,当自前级降档以来已经精确经过了所述换档时间间隔(Δt)时进行每级降档。
