A method for controlling the state of a drivetrain comprising a set of couplers and reducers (4, 5) between a powertrain (2, 3) of a motor vehicle and one or a plurality of drive wheels (6, 7) of the vehicle, the drivetrain being capable of taking up a plurality of kinematic states each defined by a diagram of engagements (Rappth, RappE) of the couplers and reducers (4, 5) making it possible to link an engine (2, 3) of the powertrain to at least one drive wheel (6, 7), which involves calculating, before changing the kinematic state, depending on a current speed (V) of the vehicle, the current kinematic state of the vehicle and an intended kinematic state that is different from the current state, a change-of-state end speed, and comparing this change-of-state end speed with a threshold. |
