Abstract
A control device for a hybrid vehicle powered from an engine and an assist motor for supplying electric power in an amount predetermined according to running conditions of the vehicle further includes means for detecting a catalyzer temperature and correcting the predetermined assist power value according to the detected catalyzer temperature when accelerating and means for preventing the idling engine from being cut off when detected catalyzer temperature is lower than a preset temperature. This control device thus realizes rapid heating of the catalyzer device to a temperature necessary for activating the catalyzer therein by adequately correcting the assist power value of the motor according to the current catalyzer temperature when accelerating and by preventing the idling engine from being cut off while the catalyzer device has a low temperature.
