The invention relates to a control device (DC) provided in a vehicle (V) having a hybrid transmission chain comprising a heat engine (MT) coupled with a gearbox (BV) via a coupling member (OC) and an electric driving machine (MM). Said device (DC) comprises control means (MC) capable of operating the electric driving machine (MM) at a selected speed in order to drive a mechanical hydraulic pump (PHM) capable of increasing the pressure inside an accumulator (AH2) of the gearbox (BV), in the event of detecting a situation that requires a rapid increase of the hydraulic pressure inside the accumulator (AH2) at least until a first threshold when only the electric driving machine (MM) needs to operate.
