Abstract
A method controlling a state of a drivetrain including a set of couplers and reducers between a powertrain of a motor vehicle and one or a plurality of drive wheels of the vehicle, the drivetrain configured to take up a plurality of kinematic states each defined by a diagram of engagements of the couplers and reducers making it possible to link an engine of the powertrain to at least one drive wheel, the method including: calculating, before changing the kinematic state, depending on a current speed of the vehicle, a 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 the change-of-state end speed with a threshold.
