Abstract
The hybrid vehicle of the present invention has an internal combustion engine, a power storage unit for storing electric power, and a motor driven by the electric power stored in the power storage unit, the hybrid vehicle being driven by at least one of the outputs from the internal combustion engine and the motor. The drive power control apparatus comprises: a detector for detecting variations in torque produced by the internal combustion engine; a converter for converting the variation into an output from the motor, based on the detection result of the detector; a remaining charge detector for detecting remaining charge of the power storage unit or a value relating to the same; a comparison circuit for comparing the detection result from the remaining charge detector with a preset remaining charge reference value or a value relating to the same; and a controller for driving the motor, based on the output from the converter, when warming up the catalyst by retarding the ignition timing of the internal combustion engine, and when it is determined, based on the output from the comparison circuit, that the detection result from the remaining charge detector is equal to or above the r…
