A device (DC) controls the coupling/uncoupling of a first prime mover (MM1), via first coupling means (MC1) to a first wheelset (T1) of a vehicle (V) also comprising a second wheelset (T2), and a second prime mover (MM2) able to be coupled to said second wheelset (T2) via transmission ratio-change means (BV) and which intervenes during changes in the transmission ratio of these means (BV). This device (DC) comprises control means (MCT) designed, in the event of a decision to change the transmission ratio, to at least temporarily prevent a change in the state of coupling of the first coupling means (MC1) during this change in transmission ratio when at least one predefined condition relating to a type selected from a type of change of coupling state and a type of change of chosen transmission ratio, is met.
