<P>PROBLEM TO BE SOLVED: To provide an engine operation control device of a hybrid electric vehicle which can eliminate and reduce a sense of incongruity about engine revolution feeling against accelerator operation and, prevent a drop in battery voltage caused by quick accelerator operation. <P>SOLUTION: When a quantity of accelerator operation is detected by a means 8 for detecting the quantity of accelerator operation, accelerator operation speed is calculated by a means 61 for calculating the accelerator operation speed based on this detected information. Then a rate of change of the targeted opening of the throttle of an engine at the time of power generation is set by a means 62 for setting the rate of change of the targeted opening of the throttle corresponding to the accelerator operation speed. Thus, engine revolution speed is quickly increased in relation to the quick accelerator operation, and the sense of incongruity against the accelerator operation can be eliminated. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
