Abstract
An electric power generation control method in a hybrid vehicle. A target generator output is calculated based on a state of charge, a catalyst temperature, etc., and the target number of engine revolutions is calculated based on the target generator output. A field current is corrected in response to the comparison result between a control target range determined in response to the target number of engine revolutions and the detected number of engine revolutions, thereby performing target control of the number of engine revolutions. Then, a correction amount of a throttle angle is set in response to the comparison result between a control target range determined in response to the target generator output and the detected generator output and the throttle angle is corrected, thereby performing target control of the generator output of a generator. Since target control of the number of revolutions is first performed and then target control of the generator output is performed, a control error caused due to engine load being high or low can be prevented. Preferred target control of the number of engine revolutions and the generator output of the generator can be performed regardless of whether engine load is high or low.
