SYSTEME ET PROCEDE DE PILOTAGE DE LA TEMPERATURE D'UN CATALYSEUR ET D'UN FILTRE A PARTICULES D'UNE LIGNE D'ECHAPPEMENT DE VEHICULE, ET VEHICULE AUTOMOBILE LES INCORPORANT

The invention relates to a system for controlling the temperature of a catalyst of an exhaust line of a hybrid vehicle, comprising a catalyst having a light-off temperature from which said catalyst is in an active mode in which said treatment is carried out. The temperature of the catalyst is controlled according to a request for instantaneous engine power by the driver and a demand on the other power source, such that it is always at least equal to the light-off temperature, and when a particle filling level threshold of the particle filter is determined as having been reached, the heat engine is controlled such that the particle filter reaches the regeneration temperature in order to be regenerated. The invention also relates to an identical method, and to a hybrid motor vehicle comprising said system.
