PROBLEM TO BE SOLVED: To provide a hybrid-vehicular control apparatus capable of appropriately executing control of engine torque and motor-generator torque to secure responsiveness to an increase in required drive torque.SOLUTION: A control apparatus includes: a require drive torque prediction part 20a for predicting an increase in required drive torque of a driver; a pre-torque increase control part 20f for increasing, when an increase in required drive torque is predicted, engine drive torque and for charging a battery by outputting, from a motor-generator, power generation torque in a magnitude of canceling the increase in the engine drive torque; a required drive torque detection part 20g for detecting an increase in the required drive torque of the driver; and a torque increase-time control part 20h for reducing power generation torque from the motor-generator in accordance with an increase in required drive torque while maintaining output of increased engine drive torque, when the increase in the required drive torque is detected.SELECTED DRAWING: Figure 3 【課題】エンジントルク及びモータ/ジェネレータトルクの制御を適切に行い、要求駆動トルクの増加に対する応答性を確保することができるハイブリッド車両の制御装置を提供すること。【解決手段】ドライバーの要求駆動トルクの増加を予測する要求駆動トルク予測部２０ａと、要求駆動トルクの増加が予測されたとき、エンジン駆動トルクを増加すると共に、モータ/ジェネレータから増加分のエンジン駆動トルクを相殺する大きさの発電トルクを出力してバッテリを充電するトルク増加前制御部２０ｆと、ドライバーの要求駆動トルクの増加を検出する要求駆動トルク検出部２０ｇと、要求駆動トルクの増加が検出されたとき、エンジン駆動トルクを増加出力したまま、モータ/ジェネレータからの発電トルクを要求駆動トルクの増加に応じて低減するトルク増加時制御部２０ｈと、を有する構成とした。【選択図】図３
