An output control apparatus for a hybrid vehicle is provided, capable of preventing stopping of the engine at the time of recovering from a deceleration fuel cut and improving the acceleration capability. In a hybrid vehicle comprising an engine, a motor for assisting the driving power of the engine, and a battery for supplying electric power for the motor, the output control apparatus comprises an engine speed sensor, an idle stop execution judgement flag F_FCEX, and a motor ECU for judging whether the output assistance by the motor is to be executed, and the motor ECU comprises a deceleration fuel cut returning time permission judgement device (S026) for permitting the output assistance by the motor, when it is judged to return from the deceleration fuel cut by the flag value of the idle stop execution judgement flag F_FCEX, and when it is detected that the engine speed at the time of returning from the deceleration fuel cut is lower than a predetermined engine speed # NEMGMOT.

1. An output control apparatus of a hybrid vehicle comprising:an engine, a motor for assisting the output power of said engine, and a battery device for supplying electric power to said motor; an output assistance judgement device for judging whether said motor should assist an output of the engine depending upon the driving conditions of said vehicle; a controlling amount setting device for setting the assisting amount of said motor depending upon a driving state of said engine when the output of the engine is judged to be assisted by said output assisting judgement device, an output assistance control device for carrying out the output assistance to said engine by said motor based on the assisting amount set by said controlling amount setting device; and an engine speed detecting device for detecting the engine speed; a deceleration fuel cut judging device for judging whether the fuel supply should be cut at the time of decelerating the vehicle and started at the time when returning from the fuel supply cut; and a deceleration fuel cut returning time permission judgement device, provided with said output assistance judgement device, for permitting the engine output assistance by said motor, when said deceleration fuel cut judging device judges that the fuel supply is to be started returning from the fuel supply cut, and when it is detected by said engine speed detecting device that the engine speed at the time of starting the fuel supply returning from the fuel supply cut is lower than a predetermined engine speed.
