1. A hybrid vehicle, comprising:

  • a motor connected to a drive shaft, which drives wheels, for rotating said drive shaft;

    an engine for generating energy required for driving said hybrid vehicle;

    a catalyst disposed in an exhaust conduit of said engine for converting gaseous exhausts;

    a generator driven by the engine; and

    a catalyst temperature control apparatus comprising;

    engine power regulation means for regulating an engine power of said engine;

    exhaust temperature detection means for measuring a temperature of either one of said gaseous exhausts and said catalyst; and

    engine power control means for, when the temperature measured by said exhaust temperature detection means is not higher than a predetermined value, carrying out a transient control that temporarily increases the engine power to raise the temperature of said gaseous exhausts via said engine power regulation means so that the temperature of the catalyst is increased to the predetermined value, wherein the transient control carried out by said engine power control means regulates an amount of electricity generated by said generator.
