Unit for controlling the power management of a heating system of a catalytic converter for a motor vehicle

A control unit for a hybrid motor vehicle with a combustion engine, said motor vehicle comprising:

• a) an electric network;
• b) a catalytic converter able to depollute the exhaust gases emitted by the combustion engine and comprising an electric heating system connected to the electric network;
• c) a battery electrically connected to the electric network, able to operate in a discharge mode, in which the battery supplies electric energy to the electric network, and in a charge mode, in which the battery is charged from the electric energy supplied by the electric network;
• d) an electric machine electrically connected to the electric network, able to operate in a generator mode, in which the electric machine supplies electric energy to the electric network, and in a motor mode, in which the electric machine generates mechanical energy from the electric energy supplied by the electric network;
• said control unit being electrically connected to the electric heating system, to the battery and to the electric machine, and being configured for:
• activating the generator mode of the electric machine;
• electrically connecting the heating system to the electric power supply network at a first time, defined after a first predetermined delay with respect to the activation time of the generator mode;
• activating the motor mode of the electric machine, at a second time, defined after the first time;
• and
• disconnecting the heating system from the electric network at a “disconnection” time, defined after the second time.
