ABSTRACT:
When a target generated output established for a generator by a target generated output setting unit depending on an operating condition of a hybrid vehicle varies, an intake air control valve control unit starts varying the opening of an intake air control valve of an engine in order to equalize the power output of the engine to a new varied target generated output. A delay time estimating unit estimates a delay time after the opening of the intake air control valve has started to vary until the engine eventually produces a power output corresponding to the new target generated output according to a preset correlation based on the present rotational speed of the engine. Upon elapse of the estimated delay time after the opening of the intake air control valve has started to vary, a generator controller increases or reduces the generated output of the generator into agreement with the target generated output. At the time the generated output of the generator is controlled, the power output of the engine matches the generated output of the generator.
