Control of charging phases of a battery of a vehicle with a hybrid powertrain

A control device for a vehicle comprising a power train including i) an internal-combustion engine able to provide a first torque and to be coupled to a gearbox, offering neutral and parking positions, by a coupling device including a hydraulic circuit and able, in a coupling position to deliver a second torque from said first torque, and ii) an electric motor installed between said coupling device and gearbox and able, in a charging phase, to produce from said second torque a third torque having a negative value opposite to that of said first torque in order to charge an associated battery, wherein it comprises;

• at least one processor and at least one memory arrange to perform operations consisting, in the event of a transition between said neutral and parking positions during a charging phase, in triggering a nullification of said third torque produced in order to nullify said first torque prior to a placement of said coupling device in a decoupling position resulting from a sudden drop in pressure in said hydraulic circuit.
