<P>PROBLEM TO BE SOLVED: To provide a power output device which prevents overcharging of a battery. <P>SOLUTION: In a hybrid car in which a carrier, a sun gear and a ring gear of a planetary gearing mechanism are connected to an engine, a first motor and a driving shaft respectively and a second motor is connected to the driving shaft, when required torque to be outputted to the driving shaft is suddenly reduced (when a value of a throttle opening annealing prohibition flag Fth is 1), fuel injection control and ignition control are carried out (S210) while target throttle opening TH* is set on the basis of target torque of the engine set from the required torque (S202) and the throttle control is executed as it is without being subjected to annealing treatment for purification of exhaust or the like with respect to the target throttle opening TH* (S208). By so doing, engine output is swiftly reduced to suppress the generation power of the first motor for receiving reaction force of the engine torque. As a result, overcharging of a battery can be prevented while corresponding to the required torque of the driving shaft which is abruptly reduced by the second motor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
