Title
(EN) METHOD FOR LIMITING THE QUANTITY OF POLLUTANTS EXPELLED BY A HYBRID VEHICLE COMBUSTION ENGINE
(FR) PROCEDE POUR LIMITER LA QUANTITE DE POLLUANTS REJETES PAR UN MOTEUR THERMIQUE DE VEHICULE HYBRIDE
Abstract
(EN)
The invention relates to a method for limiting the production of pollutants, in particular fine particles, by a hybrid vehicle combustion engine, said hybrid vehicle having a drive structure comprising said combustion engine, an electric motor, a primary shaft, and a clutch arranged between said combustion engine and said electric motor, said drive structure having an inertia, and said combustion engine having a maximum operating torque, said method comprising a phase A, a phase B and a phase C and at least the following steps: a step of measuring the speed of the primary shaft (REGAP), a step of calculating an acceleration of actual speed (REGR) of said combustion engine, said acceleration being equal to (1/INE) x min (CI, CM), and a step of regulating the actual speed (REGR) of the combustion engine according to the speed setpoint (RCONS) until said target speed (REGCI) has been reached.
