A control method is implemented in a vehicle comprising an internal-combustion engine providing a first torque and coupled to a gearbox by a coupling device comprising a hydraulic circuit and delivering a second torque from the first torque in a coupling position, and an electric motor installed between the coupling device and gearbox and producing, from the second torque, a third torque having a negative value opposite to that of the first torque to charge a battery. This method comprises a step (10-20) in which, in the event of a transition between neutral and parking positions during a charging phase, a nullification of the third torque produced is triggered to nullify the first torque before a sudden placement of the coupling device in a decoupling position.
A control method for a vehicle comprising a drive train including i) an internal-combustion engine providing a first torque and coupled to a gearbox, offering neutral and parking positions, by a coupling device including a hydraulic circuit and delivering, in a coupling position, a second torque from said first torque, and ii) an electric motor installed between said coupling device and gearbox and producing in a charging phase from said second torque a third torque having a negative value opposite to that of said first torque to charge an associated battery, wherein it comprises a step wherein, in the event of a transition between said neutral and parking positions during a charging phase, nullification of said third torque produced is triggered to nullify said first torque prior to placement of said coupling device in a decoupling position resulting from a sudden drop in pressure in said hydraulic circuit.
Control A control device for a vehicle comprising a powertrain 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 arranged 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.
