The invention relates to a device which includes: a drive engine (18); a mechanical transmission (16) connected to the drive engine via a clutch (18A); and a hydraulic transmission (20) having a pump (24) and n hydraulic engines (26A, 26B), n being no lower than 1, the pump being drivable by the drive engine such as to supply fluid to the hydraulic engines. According to the method: a situation where the clutch is disengaged on the drive engine (18) is detected; an output speed of the drive engine with the clutch disengaged is calculated; and displacement of the pump (24) is determined so that the pump, when driven by the drive engine having the predetermined output speed, supplies a fluid flow to the n hydraulic engines (26A, 26B) such that at least one of the operational parameters of the hydraulic engines, among the output speed and output torque of said engines, is a target parameter.
