The invention concerns a method and a device for controlling/commanding a hydraulic module installed in a hybrid vehicle, the module comprising at least one hydraulic engine driving a differential incorporated in the module, the engine having a fixed piston and a floating cylinder and being connected to a hydraulic circuit selectively at low pressure or at high pressure, the engine converting the energy coming from the pressurized fluid into mechanical energy in the form of a drive torque of the differential transmitting it to the drive wheels of the vehicle, said method carrying out, on request of a torque value (21) from the module transmitted by the control/command of the power train (52), a regulation of the engine torque, characterized in that the torque regulation is carried out according to the high and low pressure values of the hydraulic circuit and according to the angular position of the module, said regulation being carried out by controlling the pressure in the circuit.
