Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the endurance reliability of a damper disposed in an engine by protecting the damper from resonance.SOLUTION: An FF hybrid vehicle, including, in a drive system, a transverse engine, a flywheel-cum-damper, a first clutch and a motor-generator, and having an HEV mode (including an HEV WSC mode), is provided with a hybrid control module for protecting the flywheel-cum-damper from resonance in the HEV mode. The hybrid control module includes: a damper resonance determination part (S01, S02, S03) for determining resonance of the flywheel-cum-damper by detecting magnitude and frequency of vibration due to a variable component of an engine revolution speed; and a damper resonance protection part (S04, S05) performing protection operation control for the flywheel-cum-damper when resonance thereof is determined. 【課題】エンジンに設けられたダンパーを共振から保護することで、ダンパーの耐久信頼性を向上させること。【解決手段】駆動系に、横置きエンジン及びフライホイール兼ダンパーと、第１クラッチと、モータ/ジェネレータと、を備え、HEVモード（HEV WSCモードを含む）を有する。このＦＦハイブリッド車両において、HEVモードのとき、フライホイール兼ダンパーを共振から保護するハイブリッドコントロールモジュールを設ける。ハイブリッドコントロールモジュールは、エンジン回転数の変動成分による振動の大きさと周波数を検知してフライホイール兼ダンパーの共振を判定するダンパー共振判定部（Ｓ０１，Ｓ０２，Ｓ０３）と、フライホイール兼ダンパーの共振が判定されるとフライホイール兼ダンパーの保護動作制御を行うダンパー共振保護部（Ｓ０４，Ｓ０５）と、を有する。【選択図】図３
