Abstract (en)
[origin: WO2016097526A1] The invention relates to a method for heating a catalytic converter (6) mounted on the exhaust of a heat engine (2) capable of driving at least one drive wheel of a motor vehicle, said engine being associated with a reversible electric machine (15) which can operate in a generating mode or in an engine mode in which said electric machine (15) supplies part of the drive torque (C) of the vehicle, comprising: a step of starting (100) the vehicle in which a drive torque (C) of the vehicle is required; and a step of heating (600) the catalytic converter (6) until a starting temperature (θamo) of minimum effectiveness of the catalytic converter; CHARACTERISED IN THAT it also includes a step (400) of preheating the catalytic converter (6), in which the drive torque (C) of the vehicle is produced by the electric machine (15) operating in engine mode, the heat engine (2) being rotated, in the non-started state and with no fuel injection, by the electric machine (15).
