초록 ▼

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.

An electric power generation control method executed by control means in a hybrid vehicle equipped with a motor as a driving source of the vehicle; a generator for supplying a power generation output thereof to the motor; an engine for driving the generator for rotation; means for detecting the number of revolutions of the engine and a generator output of the generator; and the control means for controlling a field current of the generator and a run condition of the engine, said method comprising the steps of: determining a control target range for the number of revolutions of said engine and a control target range for the generator output of said generator; correcting the field current of said generator to a smaller value if the detected number of revolutions of said engine is lower than the control target range for the number of revolutions or correcting the field current of the generator to a larger value if the detected number of revolutions of said engine is higher than the control target range for the number of revolutions; and correcting the run condition of said engine so that when the detected number of revolutions of said engine is within the control target range for the number of revolutions, a load of said engine is increased if the detected generator output of said generator is lower than the control target range for the generator output, or the load of said engine is decreased if the detected generator output of said generator is higher than the control target range for the generator output, whereby the number of revolutions of said engine and the generator output of said generator are both controlled within their respective control target ranges.
